.~ 1 FOREWORD -

i This report supersedes a report titled "Entrainment Analysis of Shad Eggs in the Connecticut River", August 1977. The in-formation in the earlier report has been incorporated into this report,and modified as necessary to include recent revisions-in ,

shad age distribution data, minor mathematical corrections, errata, and suggestions from reviewers. Current data from 1976 and 1977 shad runs have been compared to the previous analyses ,

which were based largely on 1974 and 1975 data. In addition, this report discusses shad larval distribution studies conducted in 1976.

SUMMARY

OF ENTRAINMENT ANALYSES u- - .~. =.

Assessment of the entrainment effect on the had population was r j based on historical shad data aild site ' specific l field study data ,

j in conjunction with engineering design information. These >

information sources were then used to estimate the number and

~

t percentage of shad eggs spawned in the'Holyoke Pool that might be entrained.

Calculations of egg entrainment indica e'thAti.in ~~1974 and 1975 a total of 791,297 and 't,787,133 shad eggs, respectively, would  :

, have been entrained if the power station were operating. These represent, for these years, 2.0 and.1.8 percent of the eggs that drifted past the intake structure location and only 0.033 and 0.040 percent of the total number of. eggs estimated to have been ,

spawned in the Holyoke Pool.

A static population model was developed to' determine the effect f of entrainment mortality on the shad population. The model used -

the 1974 and 1975 shad-egg entrainment estimates to project the ,

number of breeding adult shad that would be ' removed from the i population as a result of egg entrainment. Projections of egg survival were made assuming that the population was oscillating f near equilibrium and a sensitivity analysis was performed to evaluate the effect of deviations from the assumption of an  ;

~

equilibrium population.

Using mean fecundity estimates and assuming the shad population was at equilibrium, survival of shad eggs to spawning adults was [

calculated to be 0.001 percent. Assuming the number of shad eggs i entrained each year is comparable to that esHmated from 1974 and i 1975 field data, it is estimated that fewer than 18 adult shad would be lost from the spawning run each year as a result of entrainment.  ;

From the analysis of density-dependent survival rates conducted f in the sensitivity analysis, it was concluded that density- j dependent survival does exist in the shad population. The -

analysis of density-dependent survival indicates that carrying l capacity of the Holyoke Pool shad population.at a sex ratio of f three males to one female is 48,600 . shad (95 percent  !

C.L. = 37,600-72,100) and that at the population hu ds observed {

in 1974 and 1975 (53,492 and 115,877," respectively) urvival of l

. eggs would be about 0.002 and 0.0007 percent, respectively.  ;

Using the 1974 and 1975 entrainment estimates, this would result j in the loss of approximately 16 and 12 adult fish from the j respective year classes.

l Analysis of impact indicates that the effect of entrainment due j t

to station operation will be to slightly increase the mortality e of shad in early life stages. This effect is not expected to change the size or characteristics of the existing shad S-1 t

• * ..fi ,

4 l l

i r

-l population to the extent that the decrease would be detected by ji scientific field observation or in the sport or commercial l

] k/ fishery. Assuming the 1974 and 1975 entrainment estimates are l

, j representative of the stations effects, the loss of adult- shad i i due to station operation would be considerably less than the year

{ to year variability in the breeding population as observed i betwe^n 1965 and 1975. Results of the evaluation of the 1976 and

1977 shad run data confirm the above conclusions.

Shad larvae were not considered in the calculation of entrainment effects. The larvae are in low abundance in the river water-that would be withdrawn by the intake. This appears to be a result of i their aggregation in eddy and backwater habitats and the fact ';

that shad eggs spawned above the intake drift downstream and hatch below the intake. Studies of shad larvae distribution indicate larvae are in relatively low abundance at locations  !

above the intake compared to abundances observed at most  !

locations sampled below the intake. Thus, few shad larvae are expected to be entrained. ,

' ^ 3 L' Entrainment of American shad ichthyoplankton in the intake of the

. .m .i proposed Montague Nuclear Power Station has been identified ,

. EM . during licensing procedures for the station, as an area of

'*R concern. At the request of Northeast Utilities Service Company MI (NUSCo) , Stone & Webster Engineering Corporation (S&W) has 4

4 performed an analysis of all of the available data. Operational

characteristics of the proposed intake and related station systems, life history data of the American shad in the Holyoke Y

s "

Pool, and data from NUSCo's 1974 through 1977 shad studies were reviewed and analyzed.

The purpose of this report is to present an analysis of the potential entrainment of shad eggs and larvae by the Montague

,; Nuclear Power Station makeup water intake and of the impact of entrainment of eggs on the adult shad population of the

Connecticut River.

The Montague Nuclear Power Station is a proposed 2,300 MWe generating facility located in Montague, Massachusetts. The station will have a closed-cycle cooling system utilizing cooling towers to dissipate excess heat to the atmosphere. Makeup water i for the cooling towers and other station systems will be withdrawn from the Connecticut River through a makeup water intake structure. This structure will be located on the east i

bank of the Connecticut River in the upper portion of the Holyoke Pool (the stretch of the Connecticut River between the Holyoke and Turners Falls Dams) .

Although the intake is designed to minimize the entrapment and impingement of fishes, entrainment of fish eggs and larvae will occur with the makeup withdrawal. Past studies of the Connecticut River indicate that American- shad spawn from the river mouth (km 8) to just downstream of the Turners Falls Dam (km 197) . However, studies of the Holyoke Pool indicate that the area upstream of the intake location is used, to a varying extent i each year, for shad spawning. Therefore, the eggs and larvae j produced upstream of the station intake would be susceptible to l

.l entrainment if they drift downstream past the in?ake. I

?

-- ; To evaluate the impact of potential entrainment on the [

-l Connecticut River shad population, station design parameters,

'l river flow conditions, and historical data on shad biology were  ;

] compiled and compared. Studies have been conducted on the i 1

.t Connecticut River shad population for several years.

i Considerable information has been recorded on their life history,

including data on their distribution and abundance, age and growth, migration patterns, food habits, and their reproductive behavior. These studies have been conducted primarily by the University of Massachusetts Cooperative Fishery Research Unit

/ ,. (MCFRU) , Essex Marine Laboratory, and the U.S. Fish and Wildlife V

Service. Evaluation of these data in late 1973 and early 1974 f determined that the impact on the shad population would be minor.

E %. '

i To more accurately identify the effects of station operation on j shad population, NUSCo funded additional shad spawning studies, l conducted by the MCFRU from 1974 through 1977. These studies were designed to provide additional data on shad spawning in the vicinity of the intake and to confirm the results of previous studies of shad behavior. The life history characteristics of

. American shad migrating above the Holyoke Dam during the 1974 through 1977 spawning runs were studied by Foote (1976) and Russo d

(1976, 1977). The numbers and timing of the shad run, and the fecundity, egg retention, sex ratio, and age class composition of shad passed into the Holyoke Pool were determined. In addition, Foote (1976) measured blood lactic acid levels and immediate fishlift mortality in order to evaluate the efficiency and stress reduction of the 1975 Holyoke fishlift improvements . Gilmore (1975) and Kuzmeskus (1977) studied egg production and spawning site distribution in the Holyoke Pool and the egg density in the vicinity of the intake in 1974 and 1975, and also in 1975, Stira (1976) determined the distance downstream that the shad eggs may drift following spawning. In 1976, the distribution and abundance of shad eggs and larvae in the Holyoke Pool above Sunderland Bridge were assessed (Cave, 1977). These studieu were specifically designed to assist the prediction of impact and are not included in the review of life history (Section 2) . The effects of entrainment on the shad population in the Holyoke Pool was determined based on these MCRFU studies, historical shad ,

data, and engineering design information.

GENERAL ENGINEERING AND HYDROLOGIC DATA

!O The two units of the Montague Nuclear Power Station will have 1

i closed-cycle cooling systems utilizing cooling towers to i dissipate excess heat to the atmosphere. In

closed-cycle-

' systems, a large volume of water is continuously circulated from the cooling tower basins to the condensers .and other. heat-

' exchangers of the station and back through the cooling towers to i

the basins. The water is alternately' heated in the condensers l and cooled in the cooling towers, resulting in transfer of excess heat from the station's steam cycle to the atmosphere.

This process results in water losses from the circulating water system by evaporation, drift, and blowdown. To replace the water.

lost, makeup water will be drawn from the Connecticut River. The major heat-exchange process in the cooling towers is the evaporation of a small percentage of the circulating water flow.

Evaporation accounts for about 80 percent of the makeup requirement. Small droplets of water become entrained in the air flow through the cooling towers and are carried away as drift.

' Drift losses are negligible in comparison to evaporation. To maintain a chemical balance in the circulating water system, a small quantity of water is continuously blown down (discharged) from the system. Blowdown accounts for about 20 percent of makeup requirement. the 1

The magnitude of each of these losses will vary with station load and meteorological conditions. A small additional quantity of water will be required for use in other

station systems. The total withdrawal will vary from as little as 11 cfs during one-unit winter operation to about 82 cfs during extremely hot summer days and two-unit, full-load operation.

Annual average makeup will be about 65 cfs.  ;

1.2 INTAKE LOCATION ,

The makeup water intake will be located on the east bank of the  !

' Connecticut River at about kilometer 189. This area is shown on i j Figure 1-3. The shoreline in this area is a steep rock ledge and- .[

! the river bottom is composed of course gravel and sand. 1 The location is about 8 km downstream of the Turners Falls Dam, I which is part of the Turners Falls Project, a hydroelectric [

generating facility. Downstream of the dam and about 3 km north  !

of the intake, the Deerfield River joins the Connecticut River.  !

The U.S. Geological Survey (USGS) Montague City gaging station is

located just downstream of the confluence of these two rivers.  ;

, s

. The Holyoke Dam is located at kilometer 140, 49 kilometers e

downstream of the intaxe. The stretch of the Connecticut River [

from the Holyoke Dam to the Turners Falls Dam is generally referred to as the Holyoke Pool. j 4 -

1.3 FLOWS l 1

Connecticut River flow at Montague City has historically varied j j from the lowest observed flow of 215 cfs in 1958 to the record l l flood of 236,000 cfs in 1936 (NUSCo, 1974, Section 2.5) . l Annual average flow is about 13,500 cfs. Monthly average flows for May, June, and July, the months in which shad spawning t J

occurs, are about 25,000 cfs, 11,000 cfs, and 6,000 cfs, i j respectively (NUSCo, 1974, Section 2.5) .

As a result of a federal flood-control program authorized in the [

} '

1930's, the Corps of Engineers now maintains nine major flood-

, control projects above the Montague City gage, all of which were l built after the 1936 flood.  !

Low flows are predominantly regulated by operations of upstream <

hydroelectric facilitiea and may fluctuate hourly. When the  ;

Montague Nuclear Power Station becomes operational, a minimum  ;

continuous flow of 1,433 cf s will be passed through the Turners l Falls Project facilities (NUSCo, 1974, section 2.5) . Minimum  ;

instantaneous flow past the intake will then be 1,433 cfs plus  !

3 the contribution of the Deerfield River. j

, 1.4 DEPTHS AND CURRENTS I

I In the vicinity of the intake location, the Connecticut River is  !

confined between steep banks. The depth and current speeds vary [

! across and along the river so that there are both deep, fast j flowing channels and quieter, shallow areas. The deeper portion '

i  ! of the river cross-section is found near the west bank upstream I

; of the intake and moves across to the east bank at, and  !

'g s downstream of, the intake. As the deep channel cuts across the l; y river section it becomes wider and shallower; the river I l

! 1-2  ;

L I

r i

i l

i ,

f cross-section is nearly symmetrical a few hundred meters upstream 1 (O '

of the intake. Near the intake, however, the channel cuts close

, to the east bank, becoming narrow and relatively deep.

l Downstream, the river cross-section is broken into thirds by two ,

piers of the Boston and Maine Railroad bridge, but the deep '

channel reestablishes itself near the east bank further downstream.  ;

Generally, currents are stronger in the deep part of the river  ;

cross-section. At very low flows (about 1,000 cfs) , depths and velocities across the river in the intake vicinity vary from about 4 feet and 0.1 fps along the west side to about 15 feet and [

0.7 fps in the deepest and fastest portions of the channel.  !

Depth increases quickly with increasing flow due to the steep  !

. banks. Velocities become more uniform as flow and depth j l increase, with depths increasing by 5 feet and velocities ranging l

.from 2 to 3 fps at about 13,000 cfs. Annual peak flood flows of i 100,000 cfs are not unenmman and result in velocities of much greater than 3 fps and depths of 40 feet or more.  ;

1.5 WATER QUALITY The area of the Connecticut River in the vicinity of the intake ,

is classified by the Commonwealth of Massachusetts, Division of Water Pollution Control, as a Class B stream (suitable for  !

bathing, excellent fish and wildlife habitat, and acceptable for  !

public water supply after appropriate treatment) . Recent water ,

quality studies (Texas Instruments, 1975a, 1975b) conducted in  ;

1973 and 1974 indicate that Class B stream standards are being ,

met, with the exception of coliform bacteria. Sewage treatment plants are presently being planned or built along the Connecticut  !

River with the goal of achieving Class B standards by the '

early 1980's (Connecticut River Basin Cooperative Fishery f Restoration Committee, 1967).  !

1.6 WATER TEMPERATURE  !

Water temperatures recorded at the Holyoke Dam vary from 32*F l during winter to a maximum temperature of 870F. Temperature  :

generally increases steadily starting in late winter. Monthly [

average temperatures are in the low 40's in April, 50's in May, t mid-60*s to low 70 's in June, and mid-70's in July and August, i then decrease steadily, reaching the low 30's in December. Other '

studies in the intake area have shown no significant thermal i stratification, reflecting a high degree of mixing (NUSCo , 1974,  ;

Section 2.5) .  !

p 2 REVIEW OF LIFE HISTORY DATA ON THE AMERICAN SHAD ,

j  ; \ _.'

2.1 ADULT i

, 2.1.1 Distribution  !

! [

i The American shad, Alosa sapidissima (Family Clupeidae) , is an f i  !

anadromous fish found alona the Atlantic coast of North America L

! from the St. Johns River in Florida to the southeastern coast of l

Newfoundland (Bigelow and Schroeder, 1953) . Shad have been i successfully introduced on the west coast of the United Staties [

i j and presently range from the Mexican border to Alaska (Walburg  !

j j and Nichols, 1967) .  ;

l i In an historical review of the shad and salmon fisheries of the i

! Connecticut River, Schmitt (1971) indicated that the American i shad was formerly able to ascend the river to Bellows Falls, f Vermont, km 282. Construction of dams as early as 1798 began to i limit its range. By.1880, the construction of the Enfield Dam in [

Connecticut had limited the shad to the first 109 kilometers of l the Connecticut River, except during periods of .high water, when [

the shad were apparently able to pass over the Enfield Dam and l j ascend to the base of the Holyoke Dam. Fish passage facilities j constructed at the Enfield Dam in 1933 and a fish lift at the i Holyoke Dam in 1955 extended the shad's range to Turners Falls  !

(km 197) . .

The American shad enters the Connecticut River in the spring to I spawn. Studies indicate that the adult shad utilize the entire  !

stretch of the Connecticut River from approximately km 8 (Essex)' [

to km 197 (Turners Falls Dam) to spawn (Watson, 1970; Marcy,  ;

. .' 1969) . Below the Holyoke Dam, shad primarily use the stretch of  !

river above Rocky Hill. (km 51.5) for spawning (Marcy, 1976) . l Studies of the upstream migration of shad indicate that migration  !

is generally oriented to the main channel (Leggett and Jones, j 1973) and that shad tend to congregate prior to spawning in *

, certain sections of the river characterized by sandy bottoms  !

- (Katz , 1972) . The upstream and downstream boundaries of these i sandy areas were composed of either gravel or rock, indicative of j

. a faster rate of flow, or of mud, suggesting a slower rate of r flow. Soon after spawning is completed in late June, adult shad  !

leave the Connecticut River and migrate northward to spend the  !

summer and fall in the Gulf of Maine (Walburg and Nichols, 1967). [

During the winter months, the shad are found scattered along the [

middle Atlantic coast, where they remain until the spring  !

spawning migration.

Spawning areas have been observed in the Holyoke Pool from the t Holyoke Dam to just below the Turners Falls Dam (Watson , 1968; l Layzer, 1974; Gilmore, 1975). Two environmental factors,  !

temperature and substrate, appear to be important factors (

T- affecting the distribution of spawning areas. The rate at which i f (V j water temperature increases during the spring influences the j i

areas within the Holyoke Pool. For i O

(j distribution of spawning example, with gradually increasing temperature, spawning -is generally concentrated in the upper half of the pool,.whereas  !

with rapidly increasing temperature,- spawning appears to 'be,  :

restricted to the lower portion of the pool (Watson, 1968,-1970) .

i '

Data indicate that when water temperatures reach 20*C, the ovaries complete development and the upriver migration ceases.-  :

3 Shad prefer to spawn in shoal water with substrates varying from  :

4 I sand to rubble and do not spawn over silt, mud, muck, or bedrock.- - l' i (Scherer, 1974) i.

/

1 Refer to Section 2.1.5.7 for a more detailed discussion of the

! spatial distribution of spawning areas.

1 2.1.2 Abundance g The abundance of shad on the Atlantic coast of the U.S. appears ,

to have declined over the past 80 years. Apparently as a result  ;

I of this, the commercial shad fishery has declined from more than l 50 million pounds in 1896 to approximately 9 million pounds

between 1930 and 1960 (Walburg and Nichols,1967) .  !

The former abundance of American shad in the Connecticut River is f difficult to assess from historical records. An early estimate  !

indicates that as many as 6 million shad may have populated the  !

Connecticut River (Schmitt, 1971) . Other early accounts of the  ;

shad fisheries indicate 2,000 shad were collected in a single  ;

seine haul at Turners Falls. Another account in 1801 indicates  ;

l ,

that 3,300 to 3,500 shad were also collected in a single sweep of  !

a seine at South Hadley Falls. Table 2-1 includes the population i

estimates for the years 1935 to 1975. This table illustrates i

! that the shad population varied between a high of 1.47 million r

(1965) and a low of 247,000 (1955) during that 40-year period.  ?

i Two unsuccessful fish passageway systems were constructed at ,

Holyoke in 1873 and 1940 in an attempt to restore the shad to the j upper reaches of the river (Schmitt, 1971). The present fish l lift system was developed in 1955 and was improved in 1968 and j

,, 1969.

In 1975, the lift was modified again so that the shad could be i l  ; lifted over the dam and released into an upstream flume without [

, any physical handling. In addition, a " stub" fish lift at the l ' base of the dam, which will be completed in 1976, will pass early l j migrants over the dam. The number of fish lifted over the dam ,

has generally increased since 1955 (see Table 2-2) .

The Cooperative Fishery Restoration Program for the Connecticut .!

I River Basin has estimated that a run of 2 million fish could be i

! established in the Connecticut River in the future, based on the i

! extent of the spawning grounds between the river mouth and .

l f' Bellows Falls. An annual run of 2 million shad calls for l l 1 million fish to be passed over the Holyoke Dam, 850,000 through  !

Attainment of these goals is dependent on development of fish -

passage facilities at the dams upstream of Holyoke.

2.1.3 Age and Growth The American shad is the largest of the clupeid fishes, growing  !

to a length of approximately 760 mm (Bigelow and l Schroeder, 1953). Walburg and Nichols (1967) indicated that shad ,

1 weighing from less than 0.9 kg to more than 4 kg have been  ;

i observed in commercial catches along the Atlantic coast. Males  !

averaged between 0.9 and 1.36 kg and females between 1.36 and  !

1.8 kg. Shad have formerly been reported weighing as much as '

6.36 kg (Bigelow and Schroeder,1953) .

l ~!

Shad ranging in age from 3 to 9 years have been collected from l the Connecticut River (Walburg, 1961; Leggett, 1969). The vast  ;

majority of the run consists of shad 4 to 6 years old. Those  !

collected by Leggett, between 1965 and 1968, ranged in length l from approximately 370 to 640 mm. Between 1969 and 1973, the  ;

mean length of shad lifted over the Holyoke Dam ranged from 410 t j to 605 mm (Watson , 1970; Katz, 1972 ; Scherer, ~ 1974) . Watson  ;

(1970) observed that the shad lifted over the Holyoke Dam were 4 '

l to 6 years old.

i Most shad mature between the ages of 3 and 5 years. Bowever,  ;

differences in the growth of shad have been observed. between males and females, as well as between different' geographical {

]

l

, areas and between shad in various stages of the spawning run.  ;

Geographical differences in age at maturity are illustrated in Table 2-3. Leggett (1969) indicated that southern shad populations matured earlier than those shad spawning in more ,

, northern rivers. This trend was observed in both males and i j females, but was most pronounced in females. He noted that ihe  !

mean age at maturity of females in the St. Johns River (Florida) was 4.3 years; York River (Virginia) , 4.3 years; Connecticut .

River (Connecticut) , 4.8 years; and the St. John River (New j Brunswick) , 4.6 years.

L

! Length and weight data from several studies indicate that females i grow f aster than males and that this difference becomes greater  !

i with age (Walburg, 1960; Walburg and Nichols, 1967; PASNY, 1974a, J 1974b) (see Table 2-4) . The increase in length with age was .

j found to be greater in the more northern rivers than in southern  !

rivers (Walburg and Nichols,1967) .  !

j Length and weight data also indicate that shad in the early part [

of the spawning run are generally larger than those making up the '

remainder of the run- (Walburg , 1960; Scherer 1974) . Age and i

l length data collected from several rivers along the Atlantic 3 coast revealed that Connecticut River shad appeared to grow at a l i (Q l

faster rate than the shad from the other rivers (Leggett, 1969).

i 7_

2-3 j f

f i

! [

i l

l l

.; t i O 'Ihe Connecticut River shad were found to be significantly larger j 'J . in every age class. Leggett indicated that this rapid rate of i growth was also observed in shad inhabiting the tributaries of r the St. Lawrence River.

}

2.1.4 Food Habits -

Adult shad feed primarily on plankton while at sea, as well as on  :

fish eggs and, occasionally, small fish (Bigelow and Sccroeder, '

1953). In fresh water, adult shad feed very little, if at all.

It is believed that although food is available, it is too small i to be captured (Kalburg and Nichols, 1967). While at sea, shad i feed on plankton approximately 8 to 25 mm long, but in fresh water the most abundant plankton are copepods, which rarely  ;

exceed 3 mm. During their spawning migration in rivers, shad are  !

taken on artificial lures. A recent study in the Hudson River -in i 1974 also indicated that shad feed very little during the spawning migration (PASNY , 1974a, 1974b) , and food items ingested included chironomid larvae, amphipods, and copepods. ,'

2.1.5 Spawning Migration 2.1.5.1 Initiation of Spawning Migration ,

The spawning migration of American shad to the Connecticut River [

from offshore waters begins in the early spring. Katz (1972) l proposed a hypothesis based on shad behavior and the effects of '

environmental factors on the initiation of migration of shad located in offshore waters. He indicated that fluctuat. tons in  !

the river or ocean temperatures are too great to be a precise i signal for migration. Since shad spend the winter in the waters l of the middle Atlantic (Sykes and Talbot, 1958) , the flow from  !

the Connecticut River cannot effect inshore movement. Katz (

(1972) , therefore, suggests that photoperiod, one f actor that is  ;

relatively consistent from year to year, may iLitiate inshore >

movement. This hypothesis has not been proven, but it may  ;

account for the initiation of the spawning migration of shad in  ;

a offshore areas.  ;

I i

The investigations of Katz (1972) , Leggett and Jones (1973), and ,

j Leggett (1976) have demonstrated the importance of terperature as i a timing mechanism for American shad migrations in the

• Connecticut River. This timing appears to be regulated by water  !

temperature (Leggett and Whitney, 1972). Leggett (1969) and Katz  ;

. (1972) have found that shad begin their upstream migration when  ;

I l river water temperatures range from 48 to 6*C. Leggett (1976)  !

noted that the time of peak movement of shad in the Connecticut I i

River is associated with the 13* to 18*C surface isotherms of the l l river. The ' shad begin to migrate upriver as the river l temperature rises and spawn when ova development is complete. I

i 2 The timing of the entry of the adults into the river ensures that l V spawning will occur at optimum temperatures for egg and larvae

f

^ development. Leggett's (1976) review of the literature showed

=

l\ / that the optimum temperatures for egg and larval deve3opment range from 15.5* to 26.5*C.

The time when American shad enter the mouth of the Connecticut ,

, River to begin their spawning migration has been reported to vary '

between the end of March and the end of April (Anonymous, 1900; ,

Nichols and Tagutz, 1960; Walburg and Nichols, 1967) . Females  !

i

! tend to enter the river later in-the season than males (Leggett, i 1976) .  !

i

. The spawning run at the river mouth lasts about 6 weeks. Leggett  !

l (1969) found that constercial catches at the river mouth increased

! with temperature until mid-May, when temperatures averaged 14' to 16*C, then declined as the water temperature continued to rise.

Delays due to the acclimation period in the transition from salt t to fresh water, physical barriers, and high flow rates, however, may slow the shad's upriver progress. As long as the water 7 temperature remains below 20*C, the shad appear to continue '

upriver migration until proper spawning conditions occur (Katz, [

1972). 1 2.1.5.2 Behavioral Responce of Shad to the Salt Wedge

~

The " salt wedge" (Meade, 1966) appears to have considerable j influence on the migration of shad at the mouth of the r Connecticut River. The salt wedge extends several kilometers >

upstream of the river mouth. The river discharge in April and May varies from 636,000 to 141,000 cfs. At high slack tide, when  ;

j the discharge is 636,000 cfs, the salt wedge extends less than ,

1.8 km upriver, and at 141,000 cfs, the salt wedge extends 11 km  !

upriver. There is also a temperature increase of up to 10*C l through the salt wedge as the cool ocean water mixes with the l warm river water.

r The behavior of fish at the saltwater / freshwater interface has  !

been examined (Dodson et al,1972; Leggett, 1976) . Fish with  !

ultrasonic tags, tracked through the upriver portion of the salt i i wedge, were observed by Leggett (1976) to meander, drift j passively, and swim slowly in the vicinity of the salt wedge.  ;

Swimming speeds of shad were lower in the area of the salt wedge,  ;

a factor attributed to physiological stress during the  !

4 acclimation to fresh water. Since sudden changes from salt to l

, , fresh water may result in mortality (Tagatz , 1961) , Leggett '

i 2 (1976) suggests that shad must adapt slowly to fresh water during i i j an acclimation period in the vicinity of the salt wedge. l l Migrating shad that were tagged have been observed to delay [

i upriver migration at the upriver extent of the salt wedge for as j long as 5 days. The length of the delay at the salt wedge  !

depended on the stage of freshwater acclimation when the fish '

3 were tagged. Following the delay at the salt wedge, fish moved (V directly upriver (Leggett, 1976).

j 2.1.5.3 Path of Migration

} (O 1

1 The path of migrating shad has been shown to be remarkably l consistent, following the natural and dredged river channel with 1

occasional movements into shallow water (Leggett, 1976) (see Figure 2-1) . Although it is not known how the shad orient to the

• i river channel, Leggett (1976) suggests that depth or river j currents may be important factors. The shad is able to adjust its swimming speed to . changes in current velocity at sea (Dodson  !

and Leggett, 1973, 1974) and in fresh water (Leggett, 1976) . The shad may, therefore, detect subtle changes in the river current.

, The higher current velocities in the river channel require the migrating shad to expend more energy when they move upriver.

However, Leggett and Jones (1973) suggest that as much energy might be wasted if shad wandered through shallow water, where there are not such strong directional cues. Migration via the river channel may, therefore, expedite upstream movement.

2.1.5.4 Rate of Upstream Movement in the Iower Connecticut River

.Between 1965 and 1973, 34,000 adult shad were tagged and released at the mouth of the Connecticut River (Leggett, 1976). The mean upriver migration rates have been calculated from the return of conventional and ultrasonic tags.

The calculated migration rate may be modified by the shad's behavioral patterns and the physical characteristics of the river at the time of tagging. The migration rate may be altered by disoriented behavior immediately after tagging, delayed migration '

at the salt wedge, water salinity, and the part of the spawning season when tagging occurred. Therefore, analysis of the data was undertaken for both conventionally and ultrasonic 1y tagged fish in an attempt to develop more than one independent estimate of migration' rates. The average migration rate was calculated for all fish tagged and recovered each year. Average migration rates (kilometers per day) were calculated for all fish tagged to determine if migration rates varied with time. "

Estimates of migration rates were also made by calculating the i average number of days since tagging for the fish recaptured at each location. The slope of the regression line for the average number of days before recapture, against the distance traveled

, from tagging to recapture site, provides another estimate of the  !

i migration rate.  ;

2.1.5.4.1 Conventionally Tagged Shad l The mean annual migration rate in the Connecticut River was based l' upon the analysis of the migration pattern of ,

6,120 conventionally tagged fish. Results of the analysis are

,, presented in Table 2-5. These mean migration rates may be low

due to delayed migration in some fish. Meandering in the lower

J most fish recover from the effects of tagging and exhibit apparently normal upstream movement within a short time. ,

, Regression analysis of the data from conventionally tagged fish

'l was corrected for the bias caused by apparent meandering I

immediately after tagging. This corrected migration rate becomes more reliable as an estimate of the migration rate.

t 2.1.5.4.2 Ultrasonic Tagging l The migration rates of shad marked with ultrasonic tags and l

} tracked periodically over several days provide accurate estimates  ;

of the migration rate. The migration rate from long-term  ;

i ultrasonic tracks is shown on Table 2-5.

~

2 .1. 5 . 4 . 3 Migration Time from River Mouth to Holyoke Dam Estimates of upriver migration rates were also made by observing the time required for fish to pass from the river mouth to  ;

Holyoke Dam during the peak abundance of shad. The migration  ;

rate calculated from the elapsed time is presented in Table 2-5. l 2.1.5.4.4 Swimming Speeds  !

l In general, the migration rates were greater in fresh water than in salt water (see Table 2-5) . These differences are supported by the differences in swimming speeds. The mean swimming speed  ;

was 2.27 km/hr in fresh water and 1.40 km/hr in salt water (see i Table 2-6) . The fish migrating in the freshwater sections of the i

, river swam faster against high currents, so that they made fairly i uniform upriver progress (see Figure 2-2) . In brackish water, however, the fish could not swim fast enough to counteract high l flows, and the rate of upriver movement (speed over bottom)  !

declined markedly (see Figure 2-2) . t l

Leggett (1976) did not find a correlation between swimming speed I and river kilometer or water temperature for shad during the upstream or downstream migration. However, he observed an apparent diel cycle in freshwater swimming speeds, with higher f speeds at 0400 and 1800 hours0.0208 days <br />0.5 hours <br />0.00298 weeks <br />6.849e-4 months <br /> (just prior to sunrise and sunset) l than at other times of the day.

2.1.5.4.5 Relationship Between Migration Rate and Swimming Speed '

-l In general, fish entering the river later in the season migrated  !

j faster. Since Leggett (1976) did not find that swimming speed  !

i increased with temperature, he concluded that shad swim more  !

i directly upstream when entering the river later in the run. l 3

Leggett also concluded that this may explain the faster migration i

! rate of females, who usually enter the river later than males. l l ($)

2.1.5.5 Passage Over the Holyoke Dam l

ihe first migrating shad of the season reach the Holyoke Dam in l early to mid-May, about 4.1 weeks after they enter the river. ,

The run continues for about 6 weeks, and the last fish are lifted ove. the dam during the last week in June. The mean time rec,uired for fish tagged at the river mouth to reach the Holyoke

. Dam was 29 days (Scherer, 1974). Peak passage over the dam l cecurs at temperatures ranging from 16.58 to 22*C (Scherer, 1974; Leggett, 1976).

i  ;

When the shad reach the Holyoke Dam, the only way they can pass over the dam is via the fishlift operated by the Holyoke Water Power Company (see Figure 2-3) . The migrating shad swim up the powerhouse tailrace or to the base of the dam and are drawn  ;

towards the fishlift area by an attraction flow. The fish are  :

forced towards the submerged hopper by a chainlink fence crowder.  !

Once the shad are in the water column above the hopper, they are j trapped by two picketed grates and the hopper is lifted up the -

fishlift tower.

i Since it was first operated in 1955, modifications have been made [

to the lift' to increase its capacity and to decrease the i mortality during the release of shad above the dam. From 1955 to 1974, the fishlift hopper was lifted to the walkway leading to the upper fishway channel and emptied into carts. These carts were wheeled across the walkway and emptied into the upper fishway channel (see Figure 2-4) .

During early 1975, an additional modification to the fish release system permitted fish to be lifted, released into an upstream -

flume, and counted as they passed a viewing window without any physical handling.

Several factors influence the number of shad lifted above Holyoke

~

Dam. Two of these, flow and temperature, have been shown to have the greatest influence on movement into the fishway.

Watson (1970) and Scherer (1974) found that the number of shad lifted over the dam depended on the flow distribution between the 3 base of the dam and the tailrace. During the early part of the i migration season, the flow over the Holyoke Dam is much larger than the tailrace flow. When the flow over the dam is high, fish  ;

I are more likely to be attracted to the base of the dam than to '

l -

the tailrace (Scherer, 1974) . Once the spring freshet subsides, I most shad move up the tailrace, since flows immediately below the dam are negligible.

i There may be some delay in migration as shad approach Holyoke, '

especially during high flow periods. Fish attracted to the base j j ,, of the dam when there are high flows generally remain there until d'

!i lower flows increase the attraction to the spillway. Oatis and j  ; Carufel (1971) tagged 1,104 fish at the dam apron and recaptured r I

, 2-8 l c -

t I I ,- _ _ -

l i

gg 19 in the fish lift. The mean time until recapture was 10.6 days lg' -

(range 2 to 24 days) . Scherer (1974) suggested that most fish at i

the base of the dam remain there until late in the lift season.

By the time the shad move out from below the dam, spawning may be unsuccessf ul because of their weakened condition from a long stay

, in fresh water and because of high water temperatures (Scherer,

, 1974). The effect of this kind of delay on American shad has not

, been studied, but other researchers have shown that a 6-day delay i in migration can prevent Pacific salmon from spawning or even reaching the spawning grounds (Scherer, 1974).

To alleviate this delay of upstream migrating shad, improvements are being made to the fish lift in 1976. The alterations include

. installation of a " stub" fish lift that will attract fish from

. , the base of the dam and increase the passage of fish early in the shad run (see Figure 2-3) .

Mean daily water temperature has a direct effect upon the variation in numbers of shad lifted. Shad have been lifted over the Holyoke Dam at mean daily temperatures ranging between 11.5*

and 25.0*C. The mean water temperature at the 3-day period of peak migration ranged from 16.5* to 22.0*C (Scherer, 1974) (see Figures 2-5 and -6). Scherer (1974) also noted the low number of shad lifted over the dam the morning after a cold night, with increasing activity as the temperature increased during the day.

Migrating shad nay drop downstream or become less active for some time after a drop in water temperature.

Although Scherer (1974) found that differences in total daily solar radiation had little influence on the numbers lifted, shad show a strong diurnal periodicity at the fish lift. Fish do not enter the fish lift area at night, even during the peak of the migration. Large numbers have been passed during twilight, but as soon as darkness occurs the shad no longer enter the lift.

Scherer (1974) suggests that fish will not pass through turbulent areas in the tailrace at night and enter the fish lift. There are often fish remaining in the tailrace area following the daily lift period. These fish are generally milling in the area of the-Hadley Station discharge. During the day, the shad eventually pass through the turbulent area and into the fish lif t.

Katz (1972) tagged 51 shad, 29 in 1970 and 22 in 1971, with ultrasonic devices and tracked them in the Connecticut River

,j above the Holyoke Dam. After the shad passed over the dam, they

{ did not immediately pass through a gate at the end of the upper fishway release channel. Instead, they would swim up and down

the release channel for periods of up to several hours. The mean time in the release channel was 38 minutes in 1970 and 25 minutes l in 1971. Katz (1972) attributed this behavior to the stress of

, passing over the dam and through the gate.

j Holyoke fish lift. Injury from overcrowdhg in the carts, '

i hitting the bottom of the upper fishway cuinnel at low water levels when being emptied into Holyoke Pool, and high temperatures may contribute to the mortality of fish lifted over the dam. These types of stress may also account for the delay in leaving the fishway channel while fish recover from handling stress and begin to orient to river flows.

Observations have been made for several years on the sex and spawning condition of fish passed over Holyoke Dam. The shad are counted, and some are sexed and measured as they pass over the dam. The ratio of males to females is affected by earlier - t

' maturation of male shad (refer to Section 2.1.3) , as well as by [

the commercial shad fishery at the river mouth. The gill nets ,

used by commercial fisherman are selective for the larger, more  :

fecund females (Walburg, 1960) . Sex ratio at the lif t generally I

ranges about three males to one female. The male: female ratio was 2.2:1 in 1956 (Tagatz, 1956) , and varied from 1.8:1 to 4.1:1 .

between 1969 and 1973 (Watson, 1970; Katz, 1972; Scherer, 1974).

Scherer (1974) reviewed the literature and found that annual i fluctuations in the sex ratio may reflect the differences in year-class strength. Both sexes are present during the entire i migration run, but as more females enter the river later in the  !

season, their frequency in the population increases. Mansueti l and Kolb (1953) reported the same relationship in the Potomac  ;

River shad run.

The spawning condition of fish lifted over the dam did not change f until late in the season. While milt could be taken from the males throughout the season, eggs could never be taken from the females (Scherer, 1974) during sampling at the lift facility; it 1 is assumed that full maturation of eggs occurs just prior to spawning. Later in the season, a number of fish that appear to have already spawned are lifted over the dam (refer to ,

Section 2.1.6) . l 2.1.5.6 Rate of Migration in the Holyoke Pool  !

In addition to delays at the b1se of the dam and in the upper  !

fishway channel, some fish would also remain in the area between i the Holyoke Dam and a bridge 0.6 km upriver. Milling, or  !

swimming without upstream or downstream progress, was observed in 7 this area for periods as long as 5 days. Exceptionally long  !

delays may be the result of an injury or stress. Katz (1972) l l suggests that milling allows the shad to rest or orient upriver

! in the low water flow. Also, the shadow of the bridge may act as 2

a behavioral barrier and delay upstream movement. Katz (1972) ,

j observed that once a fish swam under the bridge, it continued l

! steadily upstream.

l l[ The migration rate (upstream progress) of individually tracked shad varies considerabl.y. Table 2-7 lists the migration rates

j i

2-10

i (3 reported by Katz (1972) . Fish were recorded swimming upstream at

( , rates of 0.8 to 3.4 km/hr for periods longer than an hour. As the season progresses, the average migration rate decreases.

Fish appear to stop or slow down, possibly to investigate spawning sites. The shad commonly swim 16 to 24 km/ day.

Although the tagged shad swam at night, Katz (1972) attributed this to the need for gill ventilation. Nighttime tracking showed circling, milling, and downstream movement. Milling behavior was unusual in the daytime; it was most often seen before rapid upriver movement began. He also noted that about 75. percent of the upriver movement in the Holyoke Pool occurs in the first 2 days af ter the shad are lif ted over the dam.

Katz (1972) observed considerable variation in the swimming speed of individually tracked shad. The maximum upstream swimming speed recorded was 4.0 km/hr. This is an apparent speed, without correction for the river velocity that the shad was swimming against . The true swimming speed would be the sum of the apparent speed and the current velocity. Current velocities vary with the width and depth of the river in a particular location.

Correcting for river flow, (ranging from 1.6 to 3.2 km/hr when the fastest fish was tracked) , the calculated maximum swimming speed is 5.6 to 7.2 km/hr.

2.1.5.7 Spawning Areas in Holyoke Pool The selection of specific spawning areas within the Holyoke Pool appears to be dependent upon many factors, the most important being temperature, substrate type, and water velocity. Of these, water temperature is perhaps most important in determining the timing of spawning and, thus, the upstream limit of migration prior to maturation of the gonads. Watson (1970) observed that, with a sudden increase in temperature, the shad spawned mostly in the lower two-thirds of the Holyoke Pool. When temperatures increased slowly, spawning occurred in the upper reaches of the pool above Elwell Island (mn 158). Katz (1972) noted that migrating shad lifted over the Holyoke Dam early in the season, when water temperatures were slightly cooler, moved the farthest upriver. In 1970, he observed that all of the early migrants spawned in the upper fourth of the Pool, but only 17 percent of the late migrants reached that area of the river. In 1971, 57 percent of the early migrants, and none of the late migrants, i reached the upper fourth of the pool.

i The importance of substrate type and water velocity in the j selection of spawning sites has been discussed by several researchers. Layzer (1974) and Gilmore (1975) reviewed the l literature and found that shad may spawn anywhere in the river, j

over sand flats adjacent to the main channel, below creek mouths, and at the downstream end of pools. Massman (1952) and Gilmore I/ _ (1975) , however, concluded that shad prefer to spawn in the lU channel in river sections dominated by shoals. In the Holyoke i.

2-11

l Pool at Smead Island (km 192) and Canary Island (km 140) , Gilmore m

(1975) observed spawning areas over shoals, just upstream from

,: deep, fast-flowing sections of the river. From Figures 2-7 and l 2-8, it can be seen that two-thirds of the spawning grounds j identified to date in the Holyoke Pool were located at the mouths

of creeks.

Layzer (1974) and Gilmore (1975) found that shad spawn over a variety of bottom types and concluded that shad did not select one particular bottom type. Layzer's (1974) studies show that the subctrate type chosen as a spawning area could vary from sand to rubble. However, he noted that the shad did not spawn over silt, mud, muck, or bedrock.

Layzer (1974) concluded that either water velocity or flow regime is a determining factor in selecting a spawning site. He found that the river's depth at the spatining sites ranged from 0.8 to 7.5 m at most of the sites; the water velocity ranged from 53 to 67 cm/sec. Marcy (1972) collected eggs at depths of 0.6 to 7.3 m in the lower Connecticut River.

There is considerable conflict concerning the spawning sites preferred by shad. However, the literature indicates that the concentration of spawning adults is greater at upriver sections of the Holyoke Pool when the river water remains cool in the spring and is greater at downriver sections of the Holyoke Pool when the water warms early in the spring. They choose riffle areas and shoals near the river channel or downstream from creek mouths, and do not spawn over silt, mud, muck, or bedrock.

2.1.5.8 Spawning Behavior During the day, most shad remain in slow, deep pools and move into shallower water in the evening to spawn (Layzer, 1974). The time of spaening has generally been reported to occur between noon and midnight (Leim, 1924; Leach, 1925; Massman, 1952; Marcy, 1972) .

Spawning in the Holyoke Pool generally occurs in the early evening. Eggs that were collected by Layzer (1974) indicate that-most spawning occurs between 2000 and 0000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />.

Layzer (1974) also observed the swimming behavior of shad on the surface of the Connecticut River. He noted that splashing occurred from 2030 to 2145 hours0.0248 days <br />0.596 hours <br />0.00355 weeks <br />8.161725e-4 months <br />, with the peak activity from j 2130 to 2145 hours0.0248 days <br />0.596 hours <br />0.00355 weeks <br />8.161725e-4 months <br />. He also demonstrated that splashing on the j surface and spawning are related. Marcy (1972) found that shad may spawn in pairs or in groups of several males and a single

their backs out of the water. Data from 1975 studies of the l kN ,

i timing of shad spawning are presented in Section 4.

i j 2.1.5.9 Repeat Spawning .

A portion of the shad population spawn more than once during their lifetime. The proportion of repeat spawners is dependent upon the survival of individuals after spawning. The proportion of repeat spawners was determined in the Connecticut River from i

1956 to 1958 and from 1965 to 1968 by utilizing data from the

sport and commercial fisheries (Leggett, 1969) . Although there 4

were large annual variations, 38 percent.of the shad were found I to be repeat spawners. Forty-four percent of the males and 32 percent of the females were repeat spawners. Talbot (1954) reported that up to 50 percent of the Connecticut River commercial catch may be repeat spawners. The estimates of repeat spawners, like the male to female ratio, are altered by the commercial shad fishery at the river mouth. The gill nets used by commercial fishermen are selective for the larger, more fecund females, which include the larger and o.lder repeat spawners.

The higher metabolism of fish migrating in warmer waters affects i

the numbers of repeat spawners in different rivers (Leggett, 1969) . In general, the proportion of repeat spawners increases l with latitude and ranges from 3 percent in the Neuse River, North  :

Carolina, to 50 percent in the St. John River, New Brunswick.  !

The lower number of repeat spawners in southern rivers appears related to increased mortality during the spawning migration. i Leggett (1977) showed that shad return to the same river to spawn  ;

and that there is a relatively low proportion of repeat spawners i moving over Holyoke as compared to the proportion of repeat ,

spawners below Holyoke. Leggett (1977) states this would be '

expected due to heavy mortality from downstream passage past  !

Holyoke and due to the high energy expenditure required for fish {

to spawn in the Holyoke Pool. l 2.1.5.10 Weight Loss During Migration i i

Since migrating shad do not feed in fresh water, their weight loss during the spawning migration is severe. Leggett (1972) ,

reported an average somatic weight loss of 44 to 51 percent. i Female shad lost. an average of 45 percent of their somatic weight. Females lost weight more rapidly than males, and large  ;

male shad had higher overall and daily somatic weight losses than

smaller males.  !

t Leggett (1969) reported higher mortalities among fish enterix.g ,

the river late in the spawning season, when temperatures ver a above 14*C. He attributed the increased mortality to the greater j

, , use of body tissue reserves at higher temperatures. Males tend to enter fresh water early in the season, when the water i i(! N-)' temperatures are lower. Since females generally enter the river f i 2-13 i

r* weam.

h t

I i 4

lg later than males, Leggett concluded that this could explain the j - (' 'l lower weight loss and reduced mortality in males compared to (

females.

1 j 2.1.6 Fecundity i

, The number of eggs per female depends on the spawner's length, i weight, and age, and on the river in which spawning occurs s (Walburg and Nichols, 1967; Leggett, 1969). Lehman (1953) noted ,

! that fecundity is directly proportional to length, weight, and ,

age.

! The fecundity of American shad from four rivers located along the

', Atlantic coast was estimated by Leggett (1969). The mean fecundity of shad in the four rivers were: St. Johns (Florida) ,

412,000 eggs; York (Virginia) , 262,000 eggs; Connecticut (Connecticut) , 269,000 eggs; and the St. John' (New Brunswick), 155,000 eggs. Leggett noted that fecundity was highest in the southern rivers and that it generally decreased with increasing latitude. This pattern was partially masked by the large size (length and weight) of the female ahad of the -

Connecticut River.

The fecundity of female shad lif ted over the Holyoke Dam has been l estimated by Watson (1970). Using the linear relationship presented by Leggett (1969) , Watson calculated the fecundity of the adults from their length (fork length) and compared it with the observed fecundity. He found that the mean observed  ;

fecundity (148,710) in the study area was almost 40 percent lower i than the computed fecundities. Watson concluded that, since the l observed fecundities were lower than the calculated fecundities, l the fish entering the study area were partially spent. He also

. observed that some migrating shad in the fish lift were partially spent.  ;

The blueback herring (Alosa aestivalis) and the American shad are closely related species. A study in the Connecticut River above the Holyoke Dam suggests that some blueback herring had partially spawned prior to being lifted over the dam, evidenced by the .

comparatively light weight of the ovaries of certain fish and the  !

small number of eggs in the posterior section of the ovaries l (Scherer, 1972). l i

The difference between observed fecundity and calculated l fecundity detected by Watson may also be the result of the j i selective gill net fishery at the river acuth. This fishery  !

tends to select the fatter, more fecund fish in each length l

{ interval.  !

' \

Studies indicate that shad emigrating from the Holyoke Pool still l l retain a number of eggs. Watson (1970) estimated the mean egg  ;

j -

retention of 31 adult shad emigrbeing from the study area during i

fq ).

1969 to be 22,049. In July, 1970, he examined 854 female shad i i

leaving the study area and found that approximately to percent had not spawned, 33 percent were partially spent, and 57 percent ware completely spent. He concluded that egg retention must be a '

normal occurrence and not unique for any given year. A previous study of fecundity of Hudson River shad revealed that 4 shad  ;

collected on May 29, 1951 retained a mean of 22 eggs j (Lehman, 1953). Further studies of egg retention were conducted .

^

t in 1975 and are reported in Section 3.

l l t 2.2 EARLY LIFE STAGES i i 2.2.1 Distribution Spawning generally occurs in the Holyoke Pool from late May to early July. Texas Instruments (1975a, 1975b) indicated that shad  ;

eggs were also collected in the Montague area during June 1973 and during June and July 1974. The 'cajority of these eggs were  ;

collected in the near-shore areas and at night. In earlier studies, Marcy (1976) found that the eggs were almost equally i distributed between the surface and bottom.

The spatial distribution of eggs depends upon the distribution of f spawning areas (refer to Section 2.1.4) within the Holyoke Pool ,

and the downstream drift of eggs in the current. The eggs of the American shad are semibuoyant and are carried downstream as they  ;

slowly sink after spawning and as they roll along the bottom t

(Bigelow and Schroeder,1953; Schmitt, 1971; Katz , 1972) . . The f rolling movement of newly spawned eggs along the bottom may be i necessary for proper development. Katr. (1972) indicated that i artificially reared eggs must be kept moving to ensure successful -

t hatching.

The spatial distribution of larval and juvenile shad has been reported in several studies. Young shad have been reported to be most commonly found over sand or gravel bottoms (Walburg and i Nichols, 1967). Within the Holyoke Pool, however, larval shad  !

have been found to occupy specific shoreline habitats l (MCFRU , 1976). Scherer (1974) indicated that most larval shad [

were collected in certain "back-water" areas. Studies by Cave t (1977) confirm that larvae are more abundant in cove and eddy  ;

I habitats than in faster moving portions of the river and that they tend to be more abundant in the river between the intake

, location and the Sawmill River than above the intake location.

Details of Cave's study are discussed in Section 6 of this i 4

Aquatic surveys conducted by Texas Instruments (1975a, i

1975b) in the Montague area indicated that the majority of l l  ! juvenile shad collected were collected near the shore. Studies .

j l concerning the distribution of juvenile shad between the Holyoke  !

concentrated in the lower half of the Holyoke Pool j ( .,

t l 2.2.2 Abundance

' The abundance of young shad appears to fluctuate annually. Young i shad were collected in the Holyoke Pool between 1970 and 1973 by [

Scherer (1974). The greatest number was collected in 1970; the ,

~

lowest number was collected in 1973. Although the majority of these shad were juveniles, a f ew larvae were also collected. L i

When combining his data with similar data for 1968 and 1969 l

, (Watson, 1970) , Scherer noted that the abundance of young shad.  ;

• was very low in 1968 and 1973 and that the abundance appeared to be related to the number of adult shad lifted over the dam and to river conditions. For example, in 1968 and 1973, fewer adult ,

t shad were lifted over the dam; in July 1968 and 1973, high water flows also occurred. Scherer concluded that egos and larvae may have been flushed from the pool during high river flows. Marcy (1969) also noted that in 1968 juvenile shad were relatively less ,

abundant in the lower portion of the Connecticut River than in  !

previous years. He attributed this to an increase in the mortality of eggs spawned during the critical time of spawning. ,

The mortality appeared to be a result of lower water temperature  !

and increased water flow during this period. Although few ,

estimates are available for the survival of each early life I stage, estimates of the survival of shad eggs to spawning adults was investigated by Leggett (1969). Results of studies on the i St. Johns, York, and Connecticut Rivers indicated that in all l three rivers the survival of eggs is approximately 0.001 percent or one mature adult produced per 100,000 eggs spawned.

Ichthyoplankton surveys were conducted in 1973 and 1974 in the )

vicinity of the intake by Texas Instruments (1975a; 1975b). The only American shad larvae were collected on June 26, 1974 These i larvae accounted for 1.7 percent of the total catch of  ;

ichthyoplankton on that date.

t Data concerning the size of the juvenile shad population in the Holyoke Pool are limited. Watson (1970) estimated by a mark and L recapture technique that the juvenile shad population just prior to emigration was approximately 4.7 million in 1969. The upper and lower 95 percent confidence limits were determined to be j 8.9 million and 2.2 million, respectively.

j! 2.2.3 Age and Growth

$ Under experimental conditions, Leim (1924) noted that at 12*C,

!' shad eggs hatched in 12 to 15 days, and at 17*C, they hatched in [

6 to 8 days. He noted that temperatures below 8'C and above 26*C l were too extreme for successful development. Marcy (1972)

("

stripped eggs from fish collected in the lower Connecticut River and reared them in the laboratory at 13.8* to 23.0*C, i j

i i 2-16  ;

+ l

f I

/7 temperatures similar to those in the river. These eggs hatched 3

!\. to 3.5 days after fertilization. Watson (1968). observed that i shad eggs reared in hatching boxes and placed in the Connecticut River in the Holyoke Pool developed in 3.5 days at temperatures of approximately 210 and 22*C. A regression (Snedecor and

+ Cochran, 1967) of the number of hours required for shad eggs. to hatch at different temperatures was calculated by Watson using the data of several investigators.

i The relationship is represented by:

i Y = 729.06 - 8.75X 1

' where: Y = Number of hours required for hatching to occur X = Mean temperature of development.

The correlation coefficient was determined to be 0.93. The regression indicates that the time required for hatching is inversely proportional to the temperature. Utilizing this formula, Watson found that the eggs should have hatched in

} 4.5 days. He concluded that the eggs may have hatched prematurely when exposed to sunlight.

The growth of young shad is very rapid (Leim, 1924; Walburg and Nichols, 1367). Newly hatched shad larvae are between 9 and 10 mm in length (Leim, 1924). The time required for the absorption of the yolk-sac varies with temperature. Leim (1924) noted that at 12*C, absorption required approximately 7 days,-

l I

whereas at 17'c the yolk-sac was absorbed in 4 or 5 days. By the j time the yolk-sac has been absorbed, the larvae are approximately 10.5 to 13 mm in length.

Transformation of the larvae to the adult form occurs in 4 to 6 weeks, when the fish is from 25 to 28 mm in length. Growth is

! still rapid and, at the end of 2 months, some of the fish have reached lengths of 50 mm. By the end of the year, the juvenile shad are between 100 to 140 mm in length (Leim, 1924) . The mean total length of juvenile shad emigrating from the Holyoke Pool between 1966 and 1975 ranged from 97.8 to 150.4 nun (refer to Table 2-8).

The growth rate of juvenile shad in the Connecticut River has been determined in several studies between 1967 and 1973. During 1967, Watson (1968) found that juvenile shad in the Holyoke Pool i grew approximately 7.2 mm per week until the time of emigration.

Scherer (1974) also calculated the growth rate of juvenile shad and found it to be 3, 4, 10, and 7 mm per week in 1970, 1971, 4

j 1972, and 1973, respectively. He noted that the slow growth rate in 1970 and 1971 coincided with large numbers of adults litted j

into the Holyoke Pool. During 1968, Marcy (1969) indicated that 9 mm per week and j juvenile shad in the Enfield Pool grew increased in weight at the rate of 2.2 grams per week. He also l/nV) noted that the variability in length and weight during the summer 2-17 i

- - - - - - -_ _ - - + - ---- - -, . , ,,.. ,- , . , , - - -r

(

I

,.q was due, in part, to the length of the spawning season. Marcy e ' also indicated that the percentage increase in length was more rapid than the percentage increase in weight.

The mean length of juvenile shad varies throughout the Holyoke Pool. A 1967 study (Watson , 1968) of the Connecticut River above and below the Holyoke Dam revealed that juvenile shad above the dam were longer than those below the dam (130.9 and 101.2 mm, l

respectively). This pattern was found to be consistent with l previous studies in the vicinity of the Holyoke Dam. Between i l  !

, 1970 and 1973, Scherer (1974) observed that juvenile shad were l

consistently smaller near the middle portion of the Holyoke Pool

within any given week than in areas upstream or closer toshad the Holyoke Dam. He also found that the mean total length of decreased toward the end of the season and indicated that the larger individuals were probably emigrating first. Comparing data from the Holyoke Pool with data from other river studies, Scherer noted that juveniles in the Holyoke Pool reached greater mean lengths at the time of emigration.

2.2.4 Emigration until the fall before I Juvenile shad remain in fresh water migrating to sea. Emigration from the Holyoke Pool generally

< begins in September and extends into early November (Watson, 1968, 1970; Scherer,1974) . Peak migrations, however, occur at water temperatures of approximately 16*C (Scher er , 1974). By the time water temperatures have dropped below 10*C, most of the juvenile shad have left the pool.

The size of the young shad also determines when they will begin to migrate. Watson (1968) and Scherer (1974) reported that the larger juveniles begin emigrating first. Watson (1968) also indicated that ju-eniles longer than 105 mm begin to leave the Holyoke Pool when water temperatures drop below

~

18.3*C for extended periods.

Very little data are available concerning the rate of downstream migration of juvenile shad. Some swimming speed data on juvenile shad from the Susquehanna River, Maryland, are shown on Table 2-9.

I 2.2.5 Food Habits i

Stomach content analysis of larval shad collected from the j Holyoke Pool revealed that they f eed primarily on crustaceans and

' some tendipedid (Chironomidae) larvae and pupae (Levesque, 1970).

These observations are generally consistent with those of l Leim (1924) and Domermuth (1976). Some of the larger shad larvae have been found to feed on smaller shad larvae [Levesque and i Reed, 1972; Leim, 1924; Marcy, 1969) .

-l The smallest larvae containing Levesque (1970) was 16.1 rs: in food that was length. Leim collected by (1924) indicated l

-j that feeding commences soon after yolk-sac absorption. He found 1 that in the Shubenacadie River, Nova Scotia, the smallest larvae l containing food was approximately 11 mm long. Leach (1925)  ;

observed that larval shad that had been artificially propagated fed on " minute organisms" 10 to 12 days after hatching when

! approximately 16 mm long. A recent study in the Holyoke Pool  !

. j during 1972 by Domermuth (1976) also indicated that feeding did  !

, not begin until the yolk-sac was fully absorbed. The smallest larvae containing food were 10 mm long. l j

5 Levesque (1970) stated that with a 23.5 percentaccompanying increase in length (from 20.8 to 25.7 mm), there was an l 135 percent increase in the number of organisms consumed. Food consumption by larvae rapidly increases from the initial time of  ;

feeding (af ter yolk-sac absorption) to about the time they reach j 25 mm, when it begins to lessen. Levesque also noted that the l consumption of food by shad over 25 mm in length was more i proportional to an increase in body length and weight. i i

Walburg (1957) investigated the food habits of juvenile shad in six rivers along the Atlantic coast. He found their diets  !'

consisted mainly of insects and crustaceans and that their diets were similar in all the rivers. Watsons (1968) study of the i Holyoke Pool and Marcy's (1969) study of the lower Connecticut

, River revealed similar preferences. Levesque (1970) indicated that juvenile shad in the Holyoke Pool fed predominately on  ;

crustaceans, accounting for 46.1 and 33.5 percent, by volume, of ,

the stomach contents, respectively. Tendipedid larvae.and pupae,  ;

hydropsychid larvae, and adult insects were also important items  !

in their diets. Although Levesque (1970) found some traces of phytoplankton in the diets of juvenile shad, Walburg (1957) observed none. Levesque (1970) observed a shift in the diet of shad at the time of emigration to predominately crustaceans.

Both Marcy (1969) and Levesque (1970) indicated that shad are opportunistic in their feeding habits and that they normally feed <

on the most abundant organisms present. Although tubificids ,

occurred in 70 percent of the benthic samples in the Holyoke Pool l in 1960 and 1969, they were not ingested by the juvenile shad ,

(Levesque and Reed, 1972). The avoidance of tubificids as a food item was observed in another study in 1972 in the Holyoke Pool ,

(Domermuth, 1976) .  !

l The diurnal feeding pattern of young shad co13 acted from the  ;

i Holyoke Pool in July and August 1969 indicated tha'. the greatest  ;

feeding activity occurred at 2000 hours0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> (Levesque , 1970). This l observation was generally found to be consistent with other

studies (Domermuth , 1976). Marcy (1969) observed young shad

feeding at the surface in a shaded area of the Connecticut River i j( just before dark during a 2-week period in 1967. Subsequent '

) fed on winged ants i v stomach analyses revealed that they had .!

l

! 2-19 l

' (Formicidae) . Walburg and Nichols (196J) noted that shad feed I] actively at sunset and sunrise.

f7 3 BIOLOGY OF AMERICAN SHAD ENTERING HOLYOKE POOL  !

( /

~

h Adult shad studies were conducted in 1975 at the Holyoke Dam by I

, the MCFRU with funding by NUSCo. The objectives of these studies f

] were to determine the sex ratio, age class distribution of migrating female shad, and fecundity and egg retention of shad f

i' l spawning in the Holyoke Pool. Many of the parameters had been  !

l studied by previous researchers and are discussed in Section 2. j j The studies in 1975 were conducted in conjunction with a- l

! concurrent study of lactic acid levels in shad lifted over. l l Holyoke Dam (Foote, 1976). -l

-j  !

3.1 STUDY METHODOLOGY l l

1 .

3.1.1 Field Sampling i Fish were counted and sampled at the Holyoke fish lift from  ;

May 10 through June 29, 1975, the period during which the fish  !

lift operated. Adult shad were sampled from approximately every i tenth lift cycle throughout the spawning run by manipulation of l two sets of hydraulically operated gates that diverted fish into [

a holding pool. Approximately 35 shad, isolated in the holding l pool, were sampled for sex, length and weight, and scale samples. i Sex was determined by gently pressing the abdomen towards the  !

vent for evidence of the sex product (milt or eggs) . If the sex product did not appear, close examination of the vent allowed l sexual identification. Fish were measured on a standard  ;

measuring board to the nearest millimeter (total and fork j length) , and weighed to the nearest 10 grams on a Chatillion i

~

Model K0723G hanging scale. Fish scale samples were removed from l the left side, midway between the dorsal fin and lateral line.  :

l Approximately 30 to 40 scales were taken from each fish, placed in envelopes, and allowed to dry. Scales were then cleaned,  !

placed between 1-inch x 3-inch glass slides, and examined at 43X  :

on an Eberbach microprojector. Age was determined using criteria i i established by Cating (1953) and validated by Judy (1961) .  !

+

[

3.1.2 Fecundity EsHmatit a j i

i Fecundity estimates were determined from ovaries retroved from  !

l female shad collected at the Holyoke fish lift trom May 17 j j through June 27. In all, 101 shad ovaries were collected, placed '

l- t in plastic bags with a coded tag corresponding to a scale j i' envelope, and then frozen. In the laboratory, ovaries were -'

thawed and fixed for approximately 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> in 10 percent  !

formalin. After removal from the formalin, each ovary was rinsed i in water and blotted dry to remove excess moisture. Excess body mesentery was removed from the ovaries before weighing. To separate right and left lobes of the ovary, the dorsal mesentery between the ovary's right and left lobe was cut, as were the right and left ducts leading to the common oviduct. No external A ovarian tissue was removed. Each ovary half was then weighed to d the nearest milligram on a Mettler Type SH balance.

3-1

l I /D A modification of Lehman's (1953) sampling technique was used to -

( / subsample ova contained in each ovary half. Three core sections i

(rather than cross-sections) were removed from the anterior,

) central, and posterior regions of each ovary half, yi.1 ding six j subsamples. The use of a 5/16-inch piece of copper tubing  ;

facilitated this subsampling, producing core sections nearly l consistent in size and weight (approximately 1 gram) . Each core sample was then weighed to the nearest milligram and all ova

• counted. To aid in counting, the subsamples of ova were placed in 70 percent alcohol after being weighed. However, because of the difficulty and time spent in separating aggregates of ova, Davison's fluid (Henderson, 1963) was substituted for alcohol *

! midway through the study. This improved ova separation by limiting damage to individual ova. -

1 Ova were placed in a petri dish and counted with the aid of a dissecting microscope fitted with an ocular micrometer. Only mature ova (over 0.4 mm) were included in the counts i (Lehman , 1953).

To aid in computing fecundity, an ovary subsampling technique was developed. Sixteen ovaries from fish representating all age  :

classes in the spawning run were used to develop the mathematical '

relationships for the subsampling technique. A linear regression equation was developed to express the relationship between the ,

known number of ova in the central subsample of the right ovary and the mean of the three core subsamples from the left ovary.

! The resultant equation based on 16 data points was: l Y = 43.7 + 0.9247X (r = 0.997) where: -

Y = number of ova per gram in the left ovary .

P X = number of ova per gram in the central section of the  ;

right ovary -

1 r = correlation coefficient

The high r value allowed egg counts to be made by a core sample i of the central region of the right ovary (number per gram) in  !

j order to compute the mean number of ova per gram in the left j ovary.

The numbers of ova per gram for the left and right ovaries were - l l then averaged and the result multiplied by the total ovary weight  :

I to determine fecundity. '

i j 7} 3.1.3 Egg Retention Estimation In addition to the shad sampled as they were lifted over the Holyoke Dam, 79 female "downrunners" (emigrating adult shad) were collected from the Holyoke Power Company Canal system during the annual canal drawdown in early July. These fish were assumed to be representative of fish leaving the Holyoke Pool during migration back to the ocean. The number of eggs that were retained by females after the spawning season were estimated by the method used in the fecundity study described earlier.

, Because of the greatly reduced size and flaccid condition of the

spent or partially spent ovaries, subsamples of approximately 0.3 gram, rather than 1-gram samples, were used for egg retention estimates.

Eighteen ovaries from the "downrunners" were used for regression analysis to verify the subsampling technique. These ovaries were selected from all age classes collected. A linear regression equation expressed the relationship between the known number of ova in the anterior section of the right ovary and the mean of the three core subsamples from the left ovary. Results indicated that sampling of only the right anterior section per ovary pair was required for reliable estimates of egg retention.

Average number of ova per gram in the left ovary was calculated in the regression equation:

Y = 51.0 + 0.9181X (r = 0.9857) where Y is the number of ova per gram in the lef t ovary and X is the number of ova per gram in the anterior section of the right

, ovary.

The numbers of ova per gram for the left and right ovaries were then averaged and the result multiplied by the total ovary weight to compute the number of eggs retained.

3.2 RESULTS AND DISCUSSION 3.2.1 Numbers of Shad Lifted at Holyoke Dam A summary of the daily lift records of the 1975 shad run is presented in Table 3-1. The relationship of temperature and cumulative shad lift is presented in Figure 3-1. The number of shad lifted in 1975 was 115,877. Several factors may affect the number of shad actually passed alive into the Holyoke Pool.

Mortality in the fish lift and fish trap resulted in the loss of

1,631 fish from the run. A small number of fish (170) were removed from the run for lactic acid testing. In addition, 948 shad were removed and transported to Northfield and 642 were

~'

transported to Rhode Island for stocking. Consequently, 112,352

! adult shad were released alive into the Holyoke Pool. The fate

.s_) of all fish lif ted over Holyoke Dam is presented in Table 1-2.

3-3 i

i

i .

,q The shad run over Holyoke Dam represents 19.4 percent of the

i/ total estimated 1975 Connecticut River shad run of 598,000 shad l i

' (refer to Section 2.1.2) . The number of shad lifted over Holyoke >

Dam in 1975 exceeds by 76.8 percent the prior lift record of 65,527 shad observed in 1970 (refer to Table 2-2) . This appears (

i to be related to the abundance of 1970 and 1971 year class  ;

individuals of Connecticut River shad as well as to improvements l in the Holyoke Dam fish lift capacity and design.  !

j Assuming that adult shad which were released alive into the (

Holyoke Pool did not drop back over the Holyoke Dam or enter the (

.j Holyoke Canal system, the 112,352 shad represent the spawning l

' population in the Holyoke Pool in 1975. Sonic tagging data  !

! (Katz , 1972; Hughes, 1976) indicate some dropback behavior of '

tagged shad; therefore, it is possible that a small number of '

shad released above the Holyoke Dam may have moved back downstream after being counted.

i If dropback did occur, the population estimate of spawning shad

~a bove the Holyoke Dam may be somewhat inflated.- However, it is  ;

not expected to be of major significance, since extreme care was taken to reduce excessive handling of fish lifted over the dam. >

It is believed that these efforts help decrease dropback behavior ,

and that most fish continue their upstream migration following '

release above the dam.

j 3.2.2 Reproductive Parameters  ;

q 3.2.2.1 Sex Ratio The sex ratio of the 1975 Holyoke Pool shad run was 3.89 males l

per female. This indicates a slightly higher ratio of male to l

female shad than observed in previous years, when the sex ratio  ;

was approximately 3 males per female (refer to Section 2.1.5.5) .  ;

Using the 1975 ratio, it is estimated that the 1975 shad run ,

4 entering Holyoke Pool consisted of 89,376 male and 22,976 female j shad. The sex ratio of the 1976 Holyoke Pool shad run was one  :

, male to one female. This was unusual and the long run ratio is  !

expected to be three males to one female.  !

3.2.2.2 Age Class Distribution of Female Shad  !

In 1975, the age of 103 female shad lifted over the Holyoke Dam i l

was determined. Fish selected for aging were sampled throe.3hout  !

the spawning period and were assumed to be representative of the  !

age distribution of the female shad entering the Holyoke Pool.  ;

Initial results compiled by Foote (1976) indicated that age  !

classes IV and V accounted for approximately 38 and 50 percent, l

} respectively, of the female shad lifted. Studies of 109 female shad migrating over the Holyoke Dam in 1977 were conducted by the

MCFRU. In this study, age classes V and VI accounted for l 4 , approximately 49 and 44 percent, respectively, of the female shad i V examined at the fish lift. Because of this apparent dif ference 3-4 i

'! l i

. I between years and the age distribution of female shad migrating j (O over the Holyoke Dam, the MCFRU reviewed the scale reading

procedures that were utilized in both years. Review of the 1975 l data indicated'that 75 to 80 percent of the fish examined in 1975

were 1 year older than originally indicated by Foote (1976).

! Late in 1977, the MCFRU updated a report written for NUSCo in i 1975 to reflect the change in age of the lifted shad from that

. year (Reed, 1978). This update indicates age classes V and VI made up approximately 49 and 38 percent of the female shad run in

, 1975.

! These recent data are counter to historical data on the age distribution of the Connecticut River shad run. The updated data

, for 1975 indicate that the shad caught at the lif t were about 1 year older than those caught in the sport fishery (Nichols and Tagatz, 1960) , and in the combined sport /commercf.al catch reported by Leggett (1969). In addition, Foote (1976) criticized in his thesis the sampling procedures utilized by Leggett (1969) , saying they may have been biased. toward larger, older females. Considering all the available data on shad age class distribution in the Connecticut River, it appears reasonable to assume that, historically, the majority of female shad spawning in the Holyoke Pool of the Connccticut River were of age classes IV and V. The recent data would appear to indicate that the age class structure of fish migrating into the Holyoke Pool is shifting towards an older mean age of spawning females.

3.2.2.3 Fecundity Of the female shad collected for the aging study, 55 were used for fecundity estimates. These shad were selected from samples collected from May 17 to June 27. Results indicate that fecundity generally increases with age, length, and weight of 4 fish. Some female shad appeared to have unusually low numbers of eggs remaining in their ovaries. Apparently this is a result of 1

spawning prior to ascending the fish lift. These females were included in the calculation of fecundity, because they represent the eggs transported above Holyoke Dam by a portion of the females of each age class and because they contribute to the reproductive potential of shad entering aolyoke Pool. Results of fecundity estimates are presented in Table 3-3.

i l 3.2.2.4 Egg Retention 1

' , Downrunning shad sampled during July, following peak spawning,

. retained an average of 17,435, 23,362, and 19,287 eggs for age

! classes IV, V, and VI, respectively (refer to Table 3-4) . Egg

; retention for each age class represented from 7 to 12 percent of

; the fecundity determined for that age class in the study (refer i to Table 3-5) . The results correspond closely with those of i

Watson (1970), where mean egg retention of all f amale shad sampled was 22,049 eggs per female (refer to Section 2.1.5) .

l 4 DISTRIBUTION AND ABUNDANCE OF SHAD EGGS IN THE VICINITY OF THE MAKEUP WATER INTAKE STRUCTURE Shad are known to spawn throughout the Holyoke Pool, and recent studies (Watson, 1970, Layzer, 1974, and Gilmore, 1975) have indicated that some spawning takes place in the vicinity of the proposed intake. Because of the semibuoyant characteristic of

shad eggs and their tendency to drift a considerable distance I downstream from the spawning area before hatching (refer to Section 5) , it appears that eggs hatched upstream from the

proposed intake location and below the Turners Falls Dam may be subject to entrainment in the intake.

In 1974 and 1975, studies were conducted by the MCFRU for NUSCo of the distribution and abundance of shad eggs in the vicinity of the proposed intake structure. The objectives of the studies were to describe the distribution pattern of shad eggs passing the intake area and to quantify the shad eggs passing the intake location that could be susceptible to entrainment. In addition, other shad spawning areas throughout the Holyoke Pool were verified.

4.1 STUDY METHODOLOGY 4.1.1 Sampling Area Description and Nomenclature The studies used plankton net sampling in the intake area to determine densities of eggs in the river water. Selected sites in other areas of the Holyoke Pool were also sampled to determine their use as spawning sites.

At the proposed intake location, a permanent sampling grid (Montague grid) was established. This grid consisted of three egg-sampling transects spaced approximately 100 m apart, as shown on Figure 4-1. Three stations were established along each '

transect, spaced approximately equally across the river width.

• These correspond to west, mid-river, and east portions of the river cross-section. At each station, a set of three nets was '

set so that the nets were located at approximately 0.2, 0.6, and 0.8 depth levels measured from the water surface (see Figure

• 4-2) . These nets were assumed to represent the surface, mid-depth, and bottom strata of the river cross-section.

i For identification, transects were numbered 1 to 3 from north to south. Statioas were similarly numbered 1 to 3 from west to

} east, and the nets were numbered 1 to 3 from top to bottom. Each

transect can be identified by its single-digit locator. For l example, Transect 3 refers to the southern transect. Each

'j station can be identified by a two-digit locator. For example, Station 23 is on the middle transect, east side. Each net can be identified by a three-digit locator. For example, Net 123 is on

_ the north transect, mid-river station, and near the river bottom.

l This identification system is shown schematically on Figure'4-34 4-1 1

To assign a defined portion of the river's cross-section to'each I') sampling net, the following nomenclature was used. Refer to

- Figure 4-3.

Zone - Imaginary vertical lines were positioned along each transect at points one-third and two-thirds of the river i width, where the width is defined by the water surface at i elevation 110 feet mala These two lines and the east and l west shorelines then define the horizontal boundaries of  :

, three zones. The vertical boundaries are the river bottom l I

and surface. The three zones of a transect are of equal width only at a stage of 110 feet ms1, since the shoreward boundaries vary with river stage. The west and east zones

! are wider at higher stages and narrower at lower stages, i while the middle zone is of fixed width. Zones are' identified by the same numbering system as the stations, with l each zone on a transect containing a single station.

Sector - This is the portion of the cross-section of the river associated with a sampling net. Each zone is divided into three sectors, top, middle, and bottom, by the loci of points at depths of one-third and two-thirds of the height of the water column. Thus the area of each sector is one-third of the area of the zone and increases and decreases with river stage. The numbering system identifying sectors is the same as that identifying the nets within them.

Sampling at other established or suspected spawning areas is described in Section 4.1.2.

4.1.2 Sampling Gear Description Each set of buoyed gang nets (Graham and Venno, 1968) consisted of three conical plankton nets with a mouth diameter of 0.5 m and a mesh size of 0.5 mm. The nets were attached to an anchored line and sampled the surface, mid-depth, and bottom strata of the river (see Figure 4-2). During each sampling period, 27 nets were set on the grid.

The samples collected were used to characterize the egg density ,

in the water passing the sampling location during each sampling period. Each net was assumed to sample the water passing through ,

j its associated sector of the river cross-section.

t

! Water velocities at each sampling net were determined during each j sampling period by a Model 622 Gurly flowmeter. During the 1974 >

studies, velocities were measured only at the 0.2 and 0.8 depth

levels, and the time of measurement was not recorded. During l 1975, when General Oceanic flow meters were used to measure ,

l velocity, time of velocity measurements at each net were ,

i recorded. i 4 ,

, across the river at each site. The gang nets were anchored by 6.82-kg Danforth anchors; otherwise, the sampling scheme was the ,

same as that described for the permanent sampling grid. .

4.1.3 Sampling Schedule 0 ,

'. In 1974, sampling at all locations on the Montague grid began .

May 31 and ended June 24. Additional sampling was conducted at Station 3 on all transects from June 25 to July. 3. Sampling was  ;

conducted at night from 2100-2300 hours (all times are Eastern 9 Daylight Time (EDT) using a 24-hour clock) , the period of peak shad spawning (refer to Section 2.1.5.8) . Sampling was generally conducted daily throughout the period of intense shad spawning, generally the second and third week of June. A- total of 21 sampling trips were completed between May 31 and June 24, and 8 sampling trips were completed from June 25 to July 3.

In 1975, grid sampling at Montague began May 15 .and ended June 30. Sampling was begun earlier than in 1974 because of 'the passage of a substantial number of shad at the Holyoke Dam during mid-May; The 1975 run was approximately 2 weeks earlier than in 1974. The earlier run appeared to result from lower water flows t and warmer water temperatures in early May, which allowed earlier operation of the lift facilities and resulted in active upstream i migration of shad.

Sampling was conducted, as in 1974, from 2100 to 2300 hours0.0266 days <br />0.639 hours <br />0.0038 weeks <br />8.7515e-4 months <br />.

Sampling during 1975 was conducted every other night, as opposed to the every-night sampling scheme used in 1974. Analysis of 1974 data indicated sufficiently reliable data could be obtained

by alternate night sampling (refer to Appendix A) .

To determine the peak spawning period and the period when shad i eggs drift past the intake area, additional sampling was conducted from 1800-2000 hours and 0000-0200-hours on ten j sampling days.

I Limited diurnal sampling was also conducted at 2-hour intervals I

at Transect 2 to determine the diurnal distribution of the density of eggs passing the intake location. '

4.1.4 Net Efficiency i

j In 1974, high river turbidity precluded net filtration efficiency l ,. tests. Filtration efficiency was assumed to be 80 percent

,! In 1975, gear efficiency studies were conducted by Kuzmeskus

'O s. , /

(1977) concurrently with grid sampling. A gear efficiency sampling transect was established approximately 76 meters below

. Transect 3 (see Figure 4-1) . Three stations were established on this transect correrponding to the west, middle, and east sections of the river. A device was set at each station of this transect during grid sampling to evaluate net. filtration efficiency during the 2-hour sampling periods. The device consisted of two 045 m plankton net frames welded side by side approximately 0.25 m apart. One frame was rigged with a 0.5 mm

,' mesh plankton net and a General Oceanic flowmeter mounted in the center of the mouth of the net. The other net frame had only a

flowmeter mounted in the center of the net frame openinga One

.! set of sampling framec was mounted at each station at the same j { depth. The depth of sampling was rotated (surf ace, mid-depth, i

and bottom) each sampling period. The General Oceanic flowmeters were calibrated using a Velmeter flowmeter with an accuracy of

, 10.05 ft/sec at velocities less than 10 ft/sec.

Net efficiency QUE, as percent filtration) was determined using the following equation:

NE =

100 (Vw/Vwo) (4-1) where Vw = volume of water passing through the frame with a net Vwo = volume of water passing through the frame without a net.

T It was determined that an apparent decrease in net efficiency occurred after June 5, corresponding to a high concentration of cottonwood seed in the river water. Cottonwood seed caused considerably increased clogging of the net meshes thereby decreasing the filtration efficiency of the nets during the latter portion of the study. Mean net efficiencies were determined for the sampling period before June 6 and for the period from June 6 on using the first appearance of the cottonwood seed as the separation of the two time periods. This resulted in net filtration efficiencies of 76.0 percent for the period of May 15 to June 6, and 46.7 percent for samples collected from June 6 to June 304 4.1.5 Hydrologic Data Analyses i Listings of all important hydrologic parameters for each sampling j period and each sector are contained in Appendix B.

j  ! In 1975, a continuous recording depth gage was installed on the l j

d east bank of the river at Transect 2 (hereafter referred to as i the T2 gage) . Between May 19 and 29, the T2 gage was operated i  ! only during egg sampling periods. The gage was operated 1  ! continuously from May 15 to 19 and from May 29 to July 6. - Some

] difficulty with the recorder made readings from May 30 through

June 4 unusable.

i A fixed staff gage was installed on the west pier of the railroad bridge. Beginning May 29, readings were taken at the start and i end of each 2100-2300 hour sampling period and at the start and l end of most 1800-2000 and 0000-0200 hour sampling periods. The j staff gage was subject to some alteration of the flow regime l around the bridge piers, but was intended only as a check against

! drift of the T2 gage.

i i Staff gage readings were generally within 11/4 feet of T2 gage i recordings with no apparent pattern to discrepancies. Although a j few staff gage readings fell outside this range, these were i readings taken during periods of rapidly changing flow. An error j of a few minutes in recording the time of the readings would a result in considerable discrepancy in such cases. Two staff gage j readings were discarded because they did not correlate with i either T2 gage or MC gage data. These were apparently the result of reading errors.

1 Since the staff gage generally correlated well with the T2 gage,

concluded that no appreciable drift in the T2 gage occurred.

( reading of the sequence. Texas Instruments CTI, 1975b) noted, in  !

occur, a dampening of the rate-of-change of flow exists between l 4 Montague City'and the intake vicinity. Use of the third reading  ;

To determine the flow in the river, the three hourly MC gage i readings were averaged and the corresponding flow determined from the known stage-discharge relationship for that g ag e. This J

! procedure was repeated numerous times, selecting periods ,

corresponding to flows ranging from 410 cfs to 26,100 cfs. A l

regression analysis of flow and T2 stage resulted. in the .

second-order stage-discharge relationship shown on Figure 4-5. l The stage elevations determined from- this study are not in  ;

agreement with data collected during an earlier hydrographic '

study of the same area conducted by The Research Corporation of l 1 New England CTRC, 1974). This earlier study indicated water  ;

surface elevations of about 103 and 102 feet msl for flows of i about 7,000 and 5,500 cfs, respectively. Water surface  !

elevations for corresponding flows 'using the stage-discharge  !

higher (106.9 and 106.2 feet mal, respectively) . Minimum river i bottom elevations in the intake vicinity are also about the same j amount higher here than in the TRC study. It is assumed that  !

surveying or recording errors in leveling from an existing bench  !

mark in one or both studies are most likely responsible.  ;

i However, the water depths at flows of 7,000 and 5,500 cfs l determined from the two studies are in good agreement. j Based on the TRC study, a stage-discharge relationship was [

4.1.5.3 Stage-Area Relationship She cross-sectional area of each zone (Az) as a function of river j stage was determined graphically from the cross-sections of  ;

Transects 1, 2, and 3 shown on Figure 4-4. These relationships are presented in tabular form in Table 4-1.

The cross-sectional area of each sector (A) is one-third of the j area of the zone containing the sector, or A = Az/3.

4.1.5.4 Sector-Velocity and Weighting Factor Relationships In 1975, velocity was measured at each net once during each sampling period, as described in Section 4.1.2. However, as discussed in Section 1.3, river flo's w 'can vary rapidly. l Therefore, a single reading may not be representative of the .

entire 2-hour sampling period. Also, for approximately the same river flow and net location, there was a large range in the observed velocity data. Therefore, relationships were derived for the velocity at each of the 27 net locations (V1) in the sampling grid as functions of river stagea.T2 gage readings were determined for the times at which the observed velocity measurements were taken. Regression analyses resulted in the second-order relationships of velocity as a function of stage presented in Table 4-24 When the calculated value for V1 using these equations is less than 0.1 fps, V1 is assumed to be 0.1 fps, the approximate threshold of the velocity meter.

Due to location of a net within a sector, V1 may not be representative of average velocity in the sector. Therefore, a set of stage-weighting factor relationships were derived to adjust V1 values to values approximating the average velocities in each sector.

For a given transect and a selected stage, sector boundaries and net locations were drawn on the transect cross-section. Values for V1 for each net for the selected stage were plotted at the net locationsa Velocity profiles were drawn and, using the locations of these profiles and sector boundaries, average velocity (Vav) in each sector was estimated. A weighting factor, ,

W = Vav/V1, was then calculated. This process was repeated for 6

' stages from 103.9 feet msl to 112.7 feet msl and for each transect, resulting in 6 stage-weighting factor pairs for each of the 27 sectors. Linear regression analyses resulted in the first-order equations for W as a function of stage for each sector presented in Table 4-3.

4.1.5.5 Sector Flow Analyses l'~

(-)* Flow rate through each sector can initially be defined by:

Qw = A x V1 x w (4-2) where each of the terms on the right side of the equation is a function of stage.

l By continuity, the sum of the simultaneous flow rates through all nine sectors at any transect (Qtw) should equal the river flow from Figure 4-5 (Qriv). Because of the accuracy limitations in i data gathering and analyses, a small difference generally  ;

j existed. Therefore, a correction factor CWu = Qriv/Qtw) , to account for the difference, was determined and applied equally to ,

all nine sectors. The corrected sector flow is then:

Qs = Qw x Wu = A x V1 x W x Wu (4-3)

A computer program was written to perform the sector flow  ;

calculations. Input data are: j Date-time group identifying the sampling period Sector identifier (see Section 4.1.1)

Average river stage at Transect 2 during the 2-hour sampling period (Sav) .

Stage is assumed to be the same at Transects 1, 2, and 3, due to .

the short distances between them. "Sav" was determined from the T2 gage data, where available.

For periods when T2 gage data was not available a method of  !

determining "Sava from MC gage data was derived. Forty-nine 2-hour periods were selected when both MC and T2 gage data were available. These periods were selected to include several

- periods of rapidly changing river flows to include consideration of the lag time between upstream flow regulation and downstream effects. For each 2-hour period, average stage was determined for each gage, and corresponding flows were determined from the gages 5 stage-discharge relationshipsa Analysis of variance indicated no significant difference (P 5 .05) in the flows.  ;

Therefore, whenever T2 gage data were not available, "Sav" for i the sampling period was derived from MC gage data and the stage-discharge relationships for both gages.

l l 4.1.5.6 1974 Data Analyses 1

During shad egg studies in 1974, only MC gage data were obtained for stage and flow determinations. Velocity measurements were taken at the surface and bottom set nets during each sampling .

period, but time of measurement was not recorded; therefore, no

stage-area, stage-velocity, and stage-weighting factor relationships determined from the 1975 data are applicable to the 1974 data, average stage each sampling period being determined by averaging MC gage readings, as discussed in Section 4.1.5.5.-

This assumption is reasonable because there are no hydrologic characteristics that would significantly alter the geometry of

this stretch of the river.

The number of eggs drifting past tre Montague grid is dependent  ;

flow from the Smead Island spawning area to Montague has been "

4.2.3 Spatial Distribution of Shad Eggs at the Montague Grid i

I ^S ,

j ,

-j{m.' The distribution pattern of shad eggs on the Montague grid during l

l 1974 and 1975 was analyzed using analysis of variance (ANOVA) and analysis' of covariance (ANCOVA) techniques. Data used in the j ,,

l analyses were from samples collected during the 2100-2300 hour l4 , j .. ~ period on days when samples from all nets were obtained.

i i

The ANOVA used a mixed model (time as random variable) and tested L for significant differences in mean egg density due to spatial and temporal factors for 1974, 1975, and combined data for both years.. The dependent variable was egg density and the indesendent variables were time (day) , transect (1, 2, and 3),

] station (west, middle, and east) , depth (surface, mid-depth, and I

~

bottom) , and their interaction. Results of the ANOVA are given in Tables 4-5 through'4-7 for 1974, 1975, and combined data,.

respectively. The results' indicate that, with all three sets of data, . differences in egg densities,due to time,- transect, station, and depth are significant. There are no consistent

patterns of significance of interactions from the analysis of a single year of data and in the combined data. The effect of station represents most of the, variability of any independent variable in the pattern of egg densities, as indicated in the main effect and first order interactions with station effect.

Mean daily egg densities for che 2100-2300 hour periods in 1974 and 1975 are presented in Tables 4-8 and 4-9, respectively4 The mean egg densities' -in- 1974 and 1975 for the 2100-2300 hour period for transeits, stations, and depths are shown in Table 4-10. The daily egg densities generally averaged below 1.0 eggs /m3 in both ye'ars. During the period of grid sampling ~in 1974 and 1975, mean daily egg densities during a sampling period reached maxima of 21310 eggs /m3 and 1.798 eggs /m3, respectively4 High egg densi~ ties were observed at the Station 3 samples on June 26, 1974, when only those stations were sampled- at each

-transect. Although not conclusive, this may indicate that the mean density of eggs in the river on that day may have exceeded j =, the observed maximum for 1974; The distribution of eggs across the river exhibits some consibtency from year to year. In 1974, the east station had the i

' highest density of. eggs, with progressively decreasing densities

' at the west and mid-river stations. Differences between the east i

station ' and the mid-river and west stations were significant (PS'. 0 5), . In 1975, the east station again had a significantly

higher- mean density of eggs than the other stations (Ps.0 L . In l this year,"the mid-river station had the second highest density,

! with the' west statioh having the lowest density. It appears that l

1 although< the distribution pattern between stations varies from j year to . year, the ~ density of eggs at the east station is

] significantly greater than at the mid-river or west stations.

j dansity is higher on the east bank, most (73 percent in both 1974 l [,s' and 1975) of the eggs drifting downstream appear to pass the j ' -

Montague grid nearer to the east side of the river.

The depth distribution of; the eggs on the Montague Grid was generally consistent from yesr to ~ year. In both years, the density of eggs incroaaed. with depth, with a mean of

, 13.1 percent, 33.9 percent, and 53.0 percent of the egg density i

distributed at the surf ace, mid-depth, 'and bottom locations, respectively. Analysis of combined 1974 and 19",3 data indicates significant differences in ' egg density ~between all depths (Ps.05). This pattern appears related either to .the depth at

which apawning occurs or to the semibuoyant nature of the eggs.

The restits differ from data reported by Marcy (1976) for shad eggs in the vicinity of Haddam Neck in the lower estuarine portion of the Connecticut River. In studies conducted between 1967 and 1969, Marcy reported finding no difference = in the egg density distribution between surface and bottom samples.

The relationship of temperature and egg density for each _ycar is presented in Tables 4-8 and 4-9 for 1974 and 1975, respectively.

The polynoinial regression was performed with 1974 and 1975

, combined data using egg density as the dependent variable (Y) and temperature as the independent variable (x). The second degree

. polynomial, Y = -5.002 + 0.5546x -0.0137x2.- was found to fit the data satisfactorily. The density of eggs increases as river temperature approaches 200C and then the density of eggs decreases (see Figure 4-8) . These results concur closely with the optimum spawning temperatures suggested in the literature for shad in the Connecticut River (discussed in Section 2.1.2) .

To delineate the more important factors influencing the distribution of shad eggs on the Montague grid, an analysis of covariance was performed on the combined 1974 and 1975 data. In this analysis, the dependent variable was egg density and' the independent variables were year, transect, station, depth, sector flow, and temperatureA The first four variables were defined as discreet variables and the last two variables were defined as covariants. The analysis was performed using as many sources of variation and interaction as possible with the data set. Results of this analysis, after some nonsignificant variables were deleted, are presented in Table 4-11.

There is a significant difference in adjusted egg density means among the different stations, depths, and transects, and between the sample years. The difference is for the most part attributable to station.

i Temperature is highly significant, indicating a quadratic l relationship between egg density and temperature. Temperature by I

year and temperature by station interactions are also significant indicating the quadratic relationship of temperature and egg

! ' x_/', density is different in the 2 years and at the three. stations.

i The analysis indicates that station and temperature effects l account for the greatest portion of variability in shad egg

density and that year, transect, depth, and section flow effects accounted for a significant but lesser portion of the

. variability.

4.2.4 Number of Shad Eggs Drifting Past the Montague Grid To estimate the number of eggs that pass the Montague grid daily, l it was assumed that the diurnal pattern of egg drif t described in Section 4.2.2 is consistent on a daily and yearly basis. It was also assumed that the number of eggs passing the grid during the

, day is related to the number of eggs passing during the 2100-2300 hour sampling period. This relationship allows calculation of the number of eggs passing the grid by the following equation:

n E g =R X (t) dt (4-5) where: Eg = total eggs passing the intake in a given year n = number of days in the sampling period X (t) = number of eggs passing Montague during 2100-2300 hours on day t R = B/A, where B and A are the numbers of eggs passing the Montague grid from 1500-0500 hours and 2100-2300 hours, respectively, during the 10 smmpling days in 1975.

The values for X (t) were calculated from sector egg densities and hydrologic conditions using data from all transects by the i equation:

! The ratio R = B/A is calculated using data from 1975 from the.10 [

sampling days when the periods of 1800-2000 hours, I 2100-2300 hours, and 0000-0200 hours were sampled.

l 3

f to A= X(t) (4-8) i=1 where: A = total number of eggs estimated passing Montague from 2100-2300 hours during the 10 days of T sampling. l B is calculated by summing the total number of eggs passing the i grid in the period of 1500-0500 hours for each of the 10 sampling days by using Equation 4-8. However, X (t) is calculated by s

X(t) =[ Z(s) ds (4-9) l 1

where: Z (s) = number of eggs passing the grid during each of the five sampling periods from 1500-0500 hours (using data from 1800-2000 hours, 2100-2300 hours and 0000-0200 hours, and assuming no eggs pass Montague during the periods of 1500-1700 j hours and 0300-0500 hours) . j ds = time interval'between the midpoint of each  :

sampling period / time interval of the sampling period.  ;

R was calculated to be 1.657. This factor, multiplied by the.

number of eggs passing Montague from 2100-2300 hours, provides an ,

'--! estimate of the eggs drifting past the intake location either  !

! daily or yearly.

Using the above calculation, the total number of eggs drif ting  ;

past the Montague grid are:  !

Comparison between years of the number of eggs passing the grid l [-.]

'L' is complicated, because sampling in 1974 was terminated at the west and midriver grid stations prior to the end of the shad j spawning season. For this reason, the figure provided above for 3

1974 underestimates the number of eggs passing the grid. Based j on the east stations which' were sampled an additional eight

times, it is estimated the figure provided for 1974 is

! underestimated by 2.15 percent due to the early-termination of

complete sampling.* The fact that more than double the number of

shad were lifted over Holyoke Dam in 1975 than 1974 probably

, accounts for a large portion of the difference between the number of eggs passing the grid in the 2 years.

4.2.5 Distribution of Shad Spawning in Holyoke Pool Results of 1975 sampling in other portions of the Holyoke Pool increased the number of known spawning areas in the Pool to 19.

The spawning areas are distributed over the entire Holyoke Pool from Smead Island to just above the Holyoke Dam (refer to Figures 2-7 and 2-8). Most (14) of the spawning areas are located at or just downstream from small tributaries to the ,

Connecticut River. In the studies conducted in 1975, two l spawning areas were located between Elwell Island ()cn 160) and I the Holyoke Dam ()cn 140) , while previous studies had found few recently spawned eggs in samples in this portion of the river. l Discussion of the f actors af f ecting selection of spawning areas ,

l is discussed in Section 2.

5 SHAD EGG SINKING RATE AND DRIFT DISTANCE

\ '

-- The sinking rate and downstream drift of eggs is important in the i assessment of potential impact of entrainment on the shad population. If the shad eggs settle quickly to the substrate and lodge there until hatching, drifting only a short distance downstream, only eggs spawned immediately upstream of the intake j location would be susceptible to entrainment. If the eggs slowly j settle to the bottom, they may travel a considerable distance

{ downstream; then eggs spawned well above the intake would be entrainable. However, if eggs drift a considerable distance j downstream from their spawning sites, then most eggs would hatch

. below the proposed intake location. Therefore, there would be j

1 few shad larvae remaining above the intake location that would be  ;

. susceptible to entrainment as they drift downstream past the

. intake.  :

In 1974 and 1975, MCFRU investigated the size and sinking rate of fertilized American shad eggs. In 1975, the downstream distances that eggs may drift following spawning in the Montague area was also studied. Results of these studies are available from MCFRU progress reports and Stira (1976). Results relating to the analysis of impact of the Montague station are presented in this section. .

t 5.1 METHODS {

Shad eggs were collected below the Holyoke Dam by both the Massachusetts Division of Fisheries and Wildlife and the Division of Marine Fisheries. These eggs were reared in a University of Massachusetts laboratory during the 1974 studies and, during the 1975 studies, in hatching boxes placed in the Connecticut River about 1,100 m downstream of the Montague grid.

The sinking rates of non-water-hardened and water-hardened natural eggs were determined by timing their descent over a distance of 29.5 cm in a water-filled graduated cylinder. The eggs were allowed to descend approximately 13 cm, enabling them to reach terminal velocity, before timing was initiated. The

' sinking rate was corrected for temperature and normalized to 20*C, the temperature at which peak spawning generally occurs in the Connecticut River.

. 1 I Natural eggs were stained with one of three vital dyes, Trypan j blue, Neutral red, or Bismark brown Y, by immersion in a solution

! of 1 part dye to 250,000 parts water for approximately 3 to 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> immediately before release.

Geleggs (artificial gelatin eggs) were manufactured as described by Stira et al (1976). These artificial eggs were designed to match the sinking rate and diameter of natural shad eggs. The

- sinking rate of geleggs was determined in the same manner as for Ih

I i l 1

- the natural eggs. The geleggs were stained with 12 diff erent acrylic dyes.

s _s)

The mean diameters of the natural eggs and geleggs were also i determined. l 1

1

-l In the 1975 drif t distance studies, dyed natural eggs and geleggs t l

were released at several points upstream of the Montagne grid ,

. during the period of 2100-2300 hours when egg sampling was being i conducted at the grid.

I The mean sinking rate of a group of eggs released was determined  !

by measuring the sinking rate of at least 10 eggs from the group. 1 t

Mean sinking rates of geleggs were determined in the same way as

! natural eggs. The range of sinking rates of natural eggs in (

different stages of development (from non-water-hardened to ,

water-hardened) was simulated by releasing geleggs with a similar  !

range of sinking rates and sizes. All the eggs in any one group t released had similar sinking rates. I A permanent release transect, Transect O (see Figure 5-1) , was f established approximately 30 m upstream of Transect 1 of the  !

sampling grid. Releases of eggs were made at three points across j Transect 0 from May 15 to May 27, 1975, and at five points across the transect from May 31 to Jane 30, 1975. The additional release points were added to the transect to ensure more uniform l distribution of released eggs in the river water. Four other  ;

release points were established from Smead Island to Fourth t Island, about 3 km and 1.7 km upstream of the Montague grid,  ;

respectively (see Figure 5-1) . The schedule of releases from t i these points, along with the number of eggs and mean sinking rate ,

of each group, is presented on Table 5-1. Simultaneous release  !

of natural eggs and geleggs from the gaging station and upper Fourth Island were made on four dates from June 10 to June 20, 1975. These data are presented in Table 5-2.

Recaptured dyed eggs and geleggs were separated from naturally  !

occurring eggs collected in regular grid sampling (refer to l Section 4). ,

5.2 RESULTS AND DISCUSSION The mean sinking rate of non-water-hardened natural eggs is  !

1.85 cm/sec. Water-hardened eggs varied in sinking rate from i 1.12 to 1.27 cm/sec in the 197a and 1975 studies, normalized to i

. 20*C. The mean sinking rates of gelegg groups released in the i river varied from 1.00 to 1.64 cm/sec.

j Prior to water-hardening, egg shape is irregular and the diameter  ;

could not be measured. Non-water-hardened eggs are roughly half  ;

the size of fully distended water-hardened eggs. The mean ;

diameter of fully water-hardened eggs ranged from 2.83 to p 3.35 mm. Gelegg diameters ranged from 2.42 to 3.84 mm. Gnly two  ;

l h releases of geleggs were made with eggs of a greater mean l

'J.

Results of the MCFRU analysis of eggs recaptured from releases at Transect 0 indicate flow velocit.y is the major factor affecting downstream drift of released eggs.

! Simultaneous releases of dyed natural eggs and geleggs from two l upstream release points were made several times from June 10 to i

! June 20, 1975 (refer to Table 5-2) . An analysis of variance was performed to compare the downstream drift of the eggs and j geleggs. Comparisons of r..wultaneous releases indicate no i j significant difference (P 5 .05) between the number of natural

dyed eggs and geleggs recaptured at the Montague grid. This i indicates similarity in drift characteristics of the natural eggs and geleggs.

Table 5-1 contains the results of natural eggs and geleggs recaptured from releases from Smead Island and Fourth Island.

Results indicate eggs were capable of drifting downstream the 3 km from Smead Island to the Montague grid. Downstream movement below the Montague grid was not studied, but would appear likely based upon the number of eggs that were recaptured at the grid.

7 In several instances, marked eggs were recaptured at the Montague grid during grid sampling periods other than the one during which the eggs were released. Some eggs have apparent drift rates slower than others from the same release. These eggs may settle. .

a into the substrate and be subsequently washed back up into the water column by changing or turbulent flow in the river. This i

flushing action may result in considerable downstream movement of eggs spawned at or below Smead Island.

6 LARVAL SHAD DISTRIBUTION l

]

y . The distribution pattern of shad larvae in the upper portion of the Holyoke Pool is important'to the assessment of the potential impact of entrainment on the shad population. It has been shown (Section 5) that shad eggs are capable of drifting at least the 3 km downstream from Smead Island to the Montague grid. If most of the shad eggs spawned in the upper part of the pool drift past f the intake before hatching, most of the larvae should be found

below the intake. Therefore, relatively few larvae would be

subject to entrainmenta

, Two studies conducted in 1974 and 1975 partially support this j hypothesis. In the first study, Texas Instruments conducted

! ichthyoplankton sampling in the upper portion of the Holyoke Pool from May to December, 1974. Shad larvae were caught only on June 26 in low abundance (2 and 8 per 100 m3) and in only 2 of 26 samples (Texas Instruments, Inc., 1975b). In 1975, the MCFRU began a study to locate larval shad habitats in the Holyoke Pool.

Results of this study indicated larval shad utilized shoreline habitats (Reed, 1975) .

In 1976, a study undertaken by Jon R. Cave of the MCFRU was designed to assess the horizontal distribution of shad larvae.

The study also addressed the seasonal abundance and substrate and s current flow preferences of shad larvae. Larvae were defined as hatched embryos not yet exhibiting adult characteristics (about 8-18 nn total length). The remainder of this chapter is a

, detailed summary of Cave's 1976 larvae study.

6.1 METHODS i Sampling was conducted in the Holyoke Pool, Massachusetts, above the Sunderland Bridge (kms 177-192) . For comparison the sampling area was divided in two sections at the Saw Mill River (bn 184) '

(Figure 6-1) . Collections were made with a 35-foot beach seine with 1/8-inch mesh and a 4-foot bag (1 mm mesh) to determine variation in abundance of shad larvae due to horizontal distribution, different substrates, and flow regimes. Twelve seine stations were chosen, six above the Saw Mill River and six below. Three of the six sampling stations in each set were eddies and three were noneddies. Four substrates were examined:

cobble, rubble, sand, and mud. Two eddy stations were used as j substrate stations due to the limited number of sampling sites l available. This sampling design confounds analysis of the effect

. of substrate and flow on larval distribution. All twelve stations were sampled on alternate days from June 2 to July 13, 1976.

Plankton nets were towed at three stations above the Saw Mill River and three below (Figure 6-2) . Whenever possible, the east, middle, and west portions of the river were sampled. The gear "N

consisted of either 505p or 1,300u mesh nets on 1/2 and 1 m j

} 6-1 i

.. t 6

i  !

diameter hoops ,and a bongo net consisting of a pair of 1/2 m (7

hoops with nets of either mesh size. During tows, the net was situated approximately 20 feet behind the boat. General Oceanics .

j or Kahlsico flowmeters.placed in the net 'provided water volume- i filtered for.each tow. Flow speeds through the nets varied from  !

1 to 4 m/sec. Each station was sampled twice weekly throughout j l June. Variations in mesh size and tow speed are potential  ;

sources of sample variability, but the data were not segregated  ;

j by these parameters. [

t

! Six epibenthic sled stations (Figure 6-3) .were sampled five times  !

! , j throughout June. A 505 p plankton net was tied around the frame -j of the sled. All samples were taken with the sled stationary on - >

} 4 the river bottom.

I i All collections were preserved in 10 percent formalin in the field and returned to the lab. Debris was discarded and eggs and

, fish preserved in 5 percent formalin. Fish were classified as ,

either " shad" or "other" eggs, larvae, or juveniles.

i Frequency distribution of the observations indicated .that l statistical analysis could not be carried out without a  ;

transformation to stabilize the variance. A log transformation )

was used, such that-

, y = logia (x + 1) where x is the raw number and y is the transformed number. .

Analysis of variance by Multiple Comparisons (Dunn, 1961) was  !

used to indicate gross trends. Duncan's Multiple Range' Test and l Cubic Regression Analysis'and Plots were performed on Northeast  !

Utilities' Statistical Analysis System. j

} '  :

i 6.2 RESULTS AND DISCUSSION  !

Five hundred and twenty-five samples yielded 158,689 shad larvae,  ;

18,947 eggs, and 7,232 juveniles. Also, 267,254 larvae, 104 l eggs, and 42,759 juveniles of other species were collected. '

Becaus? beach seining accounted for nearly all the shad larvae, ,

tow and sled samples are not emphasized in the analysis (

(Tables 6-1 and 6-2) . Other . fish species collected consisted j

primarily of white sucker (Catostomus commersoni) , smallmouth ,

bass (Microoterus dolomieui) , tessellated. darter (Etheostoma olmstedi) , and spottail shiner (Notropis hudsonius) . The number

of shad larvae in each sample varied from 0 to many thousand,  ;

4

'; necessitating the 1cgio (x + 1) transformation. There was .

i confounding in the analysis between current and substrate because l two eddies vare also used as substrate stations. The analysis l considers each factor separately and is unable to detect any l interaction between current and substrate.

{ multiple comparison, contrast A-1 compared stations 1-6 with 7-12

(above versus below the Saw Mill River). Contrast A-2 compared stations 1-3 with 4-6 (above versus below the proposed intake, I above the Saw Mill River) . Contrast A-1 showed most of the shad I larvae to be below the Saw Mill River at a probability level that i approached significance (p <0.0 6) . Contrast A-2 showed that shad I larvae above the Saw Mill River were more abundant at stations 4-j 6 than stations 1-3 (p <0.01) .

. Trends shown in the Analysis of variance were further examined with Duncan's Multiple Range test (Table 6-4). To analyze the differences in horizontal distribution without superimposing the possible effects of differing substrates or current flows, only stations with similar 'substrates or flows were compared. Eddy stations were compared with other eddy stations for differences in horizontal distribution. Noneddy stations of the same substrate were also compared. Among eddies, stations 9, 10, and 6 had more shad larvae than station 4, while they did not differ significantly from each other. Shad larvae were less abundant at eddy stations 3 and 11 than at the other four eddies. Among noneddies, the only significant difference between stations of the same substrate was that station 5 (mud above the Saw Mill River) had more shad larvae than station 12 (mud. below the Saw Mill River).

i Analysis of tow samples was conductr i ng a one-way Analysis of variance with Station as the main m fication (Table 6-5) .

Significant differences in the distr tion of shad eggs and larvae (p <0.0001, p <0.04) were revealed, with the major concentration of both being below the Saw Mill River (Table 6-2) .

Similar analysis of sled stations (Table 6-5) showed that significant differences existed among the stations for shad larvae (p <0.04) . Again, the major concentration was below the Saw Mill River (Table 6-2 and Figure 6-4) . That most of the shad

, larvae were concentrated between stations 4 and 10, indicates that little hatching occurs above station 4. Stira (1976) documented egg drift in the upper section of the Pool. It is possible that shad eggs spawned at the upper reaches of the pool i are washed downstream as far as station 4 before they hatch. It

. is important to note that shad larval distribution in the Holyoke Pool is not limited to this study area, as recent studies have shown that shad larvae are present as far south as Holyoke, Massachusetts (Rosen, pers. comm.) .

Another factor influencing the horizontal distribution of shad 4

larvae is temperature. Watson (1970) showed that the time it takes during the spawning season for the river to warm to a certain temperature has an effect on the horizontal . distribution

! of spawning adult shad. If the river warms quickly, fewer shad 9 reach the upper areas of the Holyoke Pool before spawning.

i (x Although this effect does not bias the data within the 1976 i i sampling season, it does affect the horizontal distribution and

accurate predictions concerning horizontal distribution or

seasonal abundance in future years can be made from this data.

q 6.2.2 Seasonal Abundance t

Data were analyzed by date to describe the seasonal abundance of i the three life stages of shad. Regression analysis with linear, j quadratic, and cubic terms was performed on all seine samplesshad for shad (Table 6-6). The results were plotted as numbers of j;. . I collected [y = logga (number + 1) ] versus date to show the time pattern of abundance (Figure 6-5) . Also, untransformed abundances were plotted by date and station to detect seasonal migration of shad larvae (Figure 6-6) . Similar regression analyses were performed on tow samples (Table 6-7 and Figure 6-7). Shad larvae were shown to be most abundant during l seines and tows showed a peak in

middle and late June. Both abundance between June 15 and June 18. No seasonal migration was evidenced (Figure 6-6) , as larvae were caught in similar l

proportions at each station throughout the sampling season.

. 6.2.3 Current Type Analysis of differences in abundance at eddies versus at i noneddies was performed using Multiple Comparisons and Duncan's i Multiple Range test as before (Tables 6-3 and 6-4). The

comparisons made were

above site, above Saw Mill River, below and overall. In all cases except above site, Saw Mill River,

! shad larvae were more abundant- at eddies than at noneddiesa Abundance at eddy stations 9,10, and 6 was significantly greater i

than at all noneddy stations except station 8 (.s and). Mean

abundance at noneddy stations 8 and S (mud) was greater than mean abundance at eddy stations 3 and 11.

, There are a number of possible reasons why shad larvae were far more abundant in eddies. If the larvae are relatively weak i swimmers, they could be simply trapped in the eddy currents and unable to escape into the river flow again. However, if the 4

larvae are comparatively strong swimmers, they may select for the l

area of slower current, because it is a gathering area for food, i or because it is a less damaging habitat. Although there is no l way to definitively answer this question from this study, it is i probable that the abundance of shad larvae in eddies is a result of some combination of these or other factors.

6.2.4 Substrate

(

s) Seine stations were analyzed by substrate using Multiple Comparisons and Duncan's Multiple Range test (Tables 6-3 and 3

j 6-4). Four substrates were analyzed: cobble, rubble, sand, and j mud. In each contrast, one substrate was compared with the other

three. For each substrate, three such contrasts were made. In

-i the first, only stations oabove the Saw Mill River were j considereda In the second, only those below were considered, and

.t in the third, all stations were analyzed. Thus, contrast C-1 l compared station 1 with stations 2, 3, and 5 (Table 6-3) . Shad larvae were most abundant at stations with sand substrates

. (Contrasts- E- 2 and E-3) , and at the station with mud substrate

'] , above the Saw Mill (Contrast F-1) .

The Duncan's Multiple Range Test showed that shad larvae were more abundant at stations 8 (sand) and 5 (mud) than at the other noneddy stations. However, this may not indicate a substrate preference on the part of shad larvae for two reasons. There is a strong possibility that larvae are able to " hide" in certain substrates (cobble or rubble) and not in others. It would, in fact, seem to their advantage to do so to escape predation and damage from the current. Secondly, substrate particle size is closely related to flow speed, and differences in catches could be a result of flow, not substrate type.

6.2.5 Other Factors There are other factors not included in the study design which may have had an effect on sample variability. Stations were not standardized with respect to light exposure and vegetation cover.

! Light intensity has been related to the activity level of Atlantic herring (Cluoea harenqus) larvae (Woodhead and Woodhead, 1955). Larvae were active in complete darkness and exhibited primarily vertical movements in light levels below 100 lux.

Above 100 lux, horizontal movements increased. Because light can be a factor in affecting the activity level of clupeid larvae, the accessibility of shad larvae to sampling gear may be different under differing light levels. However, to bias the sampling, the larvae would actually have to " hide" in the substrate in certain light conditions. Although " hiding" may occur (see substrate discussion) , as a light-dependent ef fect it probably had neglig.ible effects on sampling bias.

F This study has shown that larval abundance is correlated with the

presence or absence of eddies. However, there are differences in 4 water velocity within a category of stations which could be more

, correlated to larval abundance. A station's topography and flow l characteristics might have a great deal to do with the ability of larval shad to choose their habitat. It would obviously be-difficult for larvae to remain in habitats near the main channel I

with high flow, though they might settle out in areas of lesser

! flow further from the channel. The flow regime of the Holyoke i

'l Pool also creates a " flushing" action, with daily fluctuations of i :.

)

OJ nearly a meter. Finally, the substrate analysis could be closely related to the flow characteristics of an area. Thus, the i

, different topographies of each station might be a significant factor in influencing the distribution of larval shad.

'l3 A final aspect to be discussed concerns the efficiencies, of the various gear used. Seines were responsible for most of the shad l . larvae captured. This could be a result of greater gear I

, avoidance of towed nets, or of actual distributional differences.

Examination of the cubic regression plots (Figure 6-5 and 6-7) indicates the varying ratio of eggs and larvae collected by the two gear types. Although the tows made in this study were all made at between 1 and 4 m/sec, gear avoidance could have been a i major factor. Nets were towed on the surface directly behind the boat, providing more warning than if the nets were towed at a greater distance behind the boat.

6.3 CONCLUSION

Several aspects of the distribution and abundance of American shad larvae were examined in this study. Shad larvae were found to be concentrated below the proposed Montague station intake site, although this pattern of distribution may vary in future years depending on the seasonal temperature profile. Shad larvae

• were much more abundant in eddies than in noneddies. Although substrates were identified as a factor in the distribution of shad larvae, these differences may be due to sampling biases and flow conditions rather than substrate selection by shad larvae.

This study reveals that while a few larvae will be present in the water entrained, the greatest concentrations of larvae in the upper portion of the pool are found below the intake location and are not entrainable. The average number of larvae per seine haul at Station 4 (just above the intake) was about 100 larvae in comparison to the average per station found below the intake location which packed at about 3,700 larvae for Station 9.

7 ASSESSMENT OF THE IMPACT OF ENTRAINMENT I

! .- The analysis of the impact of entrainment of shad eggs and larvae

{ on the adult population is based on:

j 1. An estimate of the number of eggs and larvae that would have been entrained had the intake been operating in

{9 4

1974 and 1975.

l } 2. A shad population model which investigates the effects l of the power plant on the adult shad population.

4 p On the basis of a review of the literature and field data

- ;i collected on shad larvae in the Holyoke Pool by the MCFRU and

! Texas Instruments, Incorporated (TI) , it is believed that few larval shad will be entrained in the intake.

i This conclusion is a supported by the following points:

{

{ 1. Few shad larvae have been captured in the free-flowing i

portions of the river during shad larval sampling by l <

several researchers (Watson, 1970; TI, 1975a, 1975b; j Scherer, 1972, 1974) .

i

2. Shad larvae inhabit backwater and eddy habitats

(Scherer, 1974; Reed, 1976) .

l 3. The shoreline near the proposed intake structure is a i

nearly vertical rock shelf that is swept by high water velocities due to the proximity of the river channel i

(refer to Section 1.4) . Because shad larvae inhabit backwater or eddy areas, there is little likelihood that

} they would aggregate in high densities near the intake

! , area.

i j 4. Results of the 1974 and 1975 shad-egg drift studies j

j (described in Section 5) indicate that some shad eggs spawned above the intake may drift downstream past the 5

intake the night they are spawned, thus decreasing the

' number of eggs that hatch above the intake. This would j

result in fewer larvae above the intake which might be susceptible to entrainment.

j 5. The 1976 shad larvae distribution study concluded that t

- shad larvae were much more abundant in eddies than in non-eddies and that the greatest concentration of shad larvae are at locations downstream of the intake (Cave, j 1977).

i Background information on these points is discussed further in Sections 2, 5, and 6. The effect on the. impact assessment of a

, violation of the assumption that no larvae will be entrained in j

j . _. the intake is discussed in Section 7.3.

~

1 7-1 I

~

l The methodology presented in the Environmental Report (NUSCo, (9)

/ 1974, Section 5.1) for determining the entrainment in the intake was based on historical data.

potential for shad egg A number i- of assumptions were made in that report.

Using these assumptions, entrainment was estimated to result in the loss of approximately 11,300,000 eggs, with a resulting decrease in the shad run of approximately 113 adult spawning shad. This would represent a 0.02 percent decrease in a shad run

averaging 500,000 fish.

t 4

' l Several of the factors used in developing many of the assumptions used in the Environmental Report can exhibit considerable annual fluctuation. As a result, the studies in 1974 and 1975

?

(discussed in Sections 3, 4, and 5) were designed to verify these j assumptions to provide a basis for the calculation of the number of shad eggs entrained during each year.

7.1 ENTRAINMENT ANALYSIS i

Because the location of the intake would be between Transects 1 ,

and 2, egg-density data from these two trans.ects were used to determine the number of eggs entrained. River water entrained by the intake will be withdrawn from the east side of the river, primarily from the mid-depth and bottom strata. The estimates of the density of shad eggs in the entrained water were determined from the mean egg density at Transects 1 and 2,, east station, mid-depth, and bottom strata sampling locations. Meteorological and typical cooling system performance data for 1974 and 1975 were used to determine makeup flow rate. Egg-density data are discussed in Section 4 and provided in Appendix B. Makeup flow -

rates are discussed in this section.

7.1.1 Number of Eggs Entrained The number of eggs that would have been entrained in the intake was determined for the 1974 and 1975 spawning seasons, based upon the projected makeup rates and the egg-density data for each year.

Makeup flows were calculated assuming both units of the Montague l Nuclear Power Station were operating at full load. Makeup flow '

is a function of ambient meteorological conditions and station

load, as discussed in Section 1. For each sampling period, the

Connecticut River. The percentage of shad egg.s passing the j station which are entrained is not necessarily equal to this percentage due to the nonuniform distribution of eggs in the river. Determination of the percentage of shad eggs passing the j station which are entrained for each year (P. is calculated i using Transects 1 and 2 egg density and hydrogha)phic data in the

P = 100 Fg /Ei (7-4) where:

year, which is calculated from Equation 4-5.

However, X (t) is calculated using only Transect 1 and 2 data (i = 1,2) .

The number of eggs passing the intake was estimated to be 3.9 x 107 in 1974 and 9.7 x 107 in 1975.

Using these figures, the percentage of all eggs passing the intake during the shad spawning season that would have been' entrained was:

, The number of eggs that would have been entrained in 1974 and 1975 can also be expressed as percentage of eggs spawned in the i Holyoke Pool.

The number of eggs spawned in 1974 is calculated based on a run of 49,595 shad entering the pool alive (excluding fish that died or were transported elsewhere) with a sex ratio of three males per one female, and on data from 1975 on age class composition,

fecundity, and egg retention. Calculation of the number of eggs

7.2 EFFECTS OF ENTRAINMENT ON THE ADULT SHAD POPULATION i

, j To determine the effect of entraining a portion of the shad eggs l .j spawned in the Holyoke Pool on the number of shad in the spawning

, i run, historical data and data from the 1974 and 1975 field studies were used to develop a static population model. The

! , static model is used to translate the number of organisms lost by j entrainment into the number of adults that would have resulted, j assuming no density-dependent mechanisms in the population (Horst, 1975)..

The model assumed the population was at equilibrium; i.e., that

( the eggs of a spawning pair result in replacement by two spawning j adults in one generation. A sensitivity analysis was also 1 conducted to investigate entrainment impact on the shad d

population if the survival of eggs to adults varies from that j estimated for the population at equilibrium.

f 7.2.1 Static Population Analysis j When a population is at equilibrium, the eggs spawned by a breeding pair will be reduced to two breeding adults in one j generation. That is, the sum of gametes spent in a lifetime by a spawning pair will result in the recruitment of another. breeding j pair. This situation is represented by the equation:

1 2=SxE g or S = 2/E s (7-5) l -

where:

i S = the survival from egg to adult 4

E = the eggs spawned by a breeding pair during their life, s and is assumed to be the mean number of eggs spawned per

}

j female in the Holyoke Pool, 193,000 eggs (ref er to Section 3.2.3) . l I l i In this case, survival (S) equals 2/193,000 or 0.001 percent. i 4

This survival estimate of shad eggs to adult is consistent with 1 that of Leggett (1969) (ref er to Section 2.2.2) . The number of i

I spawning adults (Na) that would have resulted from entrained )

Na = S x E e r Na = 2Ee /3 s

E r- the number of eggs 2 trained over the entire

• spawning period each year, calculated from Equation 7-3 1

Therefore:

1974 Na = 2 x 791,297 = 8.2 N 8 adults l 193,000 1975 Na = 2 x 1,787,133 = 18.5  % 18 adults l

' 193,000 This would represent 0.02 and 0.04 percent of the mean Holyoke Pool shad run over the past 10 years, and 0.002 and 0.005 percent of the mean Connecticut River shad run over the same period.

The above estimate of survivorship assumes an equal ratio of males to females. If the sex ratio is altered so that there are more males than females, the survivorship will increase.. That is, the "2" in equation 7-5 would become a "3" if the ratio were two males to one female, or a "4" if the ratio were three males to one female.. This is because, when the population is in equilibrium, the sum of the gametes spent by a breeding group (i.e., three males and one female) will result in the recruitment of another breeding group (three males and one f emale) .

Therefore, the increase in number of adults lost will be proportional .to the number of additional males (over the 1-to-1 ratio) in the breeding group, unless there are some density dependent factors involved. .

7.2.2 Sensitivity Analysis It is possible that the Holyoke Pool shad population will not be in equilibrium each year and that the survival of shad eggs may vary from 0.001 percent (assuming a 1:1 sex ratio). To account for this, an analysis was t:rade to determine survival rates from the egg stage to spawning adult at varying population levels.

The analysis used historical data to investigate the relationship between egg survival and the number of fish lifted over Holyoke i Dam. The observed survival rates for the Holyoke Pool shad run i were used to evaluate the effect of entrainment on the shad population if the survival rate was different than the i equilibrium survival rate.

Recruitment froml -9 each year class was calculated by summing the adjustedinumber'of . - E shad lifted at Holyoke Dam 4 and 5 years subsequent and , dividing by two (ref er to Table 7-2) . 1 The relationship of survival rate and the number of fish lifted. '

at-Holyoke Dam indicates an indirect relationship between the,two.

variables. The relationship is expressed as Y = 1352 x -1.2 m 7 (7-7}l-;;.,

af where y is survival rate and x is number of fish lifted: y ,t, .

with a correlation coefficient of -0.9135 (see Figure 7-1) . As.

expected, the survival increases rapidly as the population levels -

become very low and decreases to about 0.001 as the population increases to 85,000 shad.

This relationship between number lifted and survivorship ~(as measured by the size of the shad run 4 and 5 years later) is open to some criticism of cause and effect. Careful inspection of Table 7-2 reveals an increasing number of fish lifted and a decreasing rate of egg to adult survival through time. :It s indicates some nonbiological factors, such as experience.. gained, ,;

rate and number of shad lifted and it is assumed that these d factors do present the best available relationship between ,

survival of shad eggs and varying population sizes.  ;

4 The relationship indicates that at population levels observed in

! 1974 (51,315 shad) , survival rates of eggs to adults would have

been approximately 0.002 percent. This would result in twice as i j many fish removed from the population in the next generation as ,

was calculated using the survival rate of 0.001 percent from the I static population analysis. Extrapolation of the relationship.to  !

the population level of 115,000 fish observed in 1975 indicates  ;

that survival of the eggs would be 0.0007 percent, or a- lower l

! survival than at equilibrium levels. The interpretation of the ,

l relationship beyond the data limits must be approached carefully  ;

(refer to Section 7.3) ; however, theory and the empirical j evidence indicates the egg survival rate at the population level  ;

of 115,000 would be less than that observed for the 1974 year t class. The analysis indicates the survival of shad eggs at population levels as high as that observed in 1975 will be close l to 0.0007 percent. j i

l The relationship indicates that, for the Holyoke Pool shad runs i

between 1955 and 1970, the highest estimated survival rate was  !

0.0357 percent, based on Equation 7-7. This high surivival rate i was for the 1955 year cla as when 4,899 shad spawned in the -

Holyoke Pool. It appears density-dependent survivial factors had ,

considerable influcnce on the year class and the combined effect t of density-independent and density-dependent factors resulted in  !

very high survival.  !

If it were assumed that the survival of eggs in 1974 and 1975 was at the historical maximum (0.0357 percent) , the effect of ,

entrainment would be the loss of 283 adult shad from the 1974 '

year class and 638 shad from tte 1975 year class. These lossas i are higher than those estimated from the static model and those  !

estimated using the correction for density-dependent survival.

The occurrence of such a high survival rate at the high  !

population levels observed in 1974 and 1975 is not probable and i the entrainment losses calculated using the high survival rate  ;

remain below the existing year-to-year fluctuation in the shad l

- projection of survival of

populations ranging between 5,000 and 65,000 fish. Projection of j survival rates beyond this range, using the same relationship,

, must be . considered carefully. The relationship expressed in Equation 7-7 indicates that the population size at equilibrium (carrying cr eacity) is approximately 49,000 fish. Thus, the

- carrying capacity calculated here is lower than the carrying

, capacity estimated by Leggett (1976) (150,000 to 200,000 shad)

. , based.on analyses of available nursery habitat. Also, these ,

_results;do not concur with the evaluation of spawning and nursery {

area _ conducted by the Technical Comittee for Fisheries l Management in the Connecticut River Basin (U.S. Fish and Wildlife

' Sersice, 1967). The Technical Committee has propoced that the l Connecticut River can produce a run of up to 2 million adult fish

. if shad are allowed access to the river up to Bellows Falls.

"This. figure is based on the prediction of 2.8 adult shad produced per 100 sq yd unit of suitable spawning habitat. On the basis of this analysis, the Technical committee has proposed that the fish passage facilities at the Holyoke and Turner Falls Dams accommodate 1 million and 850,000 fish, respectively. This indicates that -approximately 150,000 adult shad could most

. efficiently use the spawning habitat available in the Holyoke  ;

j Pool. Results of a study by Northrop (1975) indicate a projected maximum sustainable Holyoke pool shad population of 250,000 adults, based on estimated area of available spawning habitat.

The above estimates of the carrying capacity of the Holyoke Pool L are higher than those estimated by the survival / population size '

relationship. Assuming the other estimates of carrying capacity more closely approximate the actual carrying capacity, the  !

survival of eggs produced by spawning runs greater than 49,000 fish may be slightly higher than that expressed by the  ;

r surviv6 / population size relationship. On the basis of estimates of car ging capacity from other sources, it would appear that as 7 the_ population grows toward a carrying capacity of 150,000 to 250,000 fish, the egg survival will approach 0.001 percent. l Future studies of the Holyoke Pool shad population may provide l better definition of the relationship of survival rate and size i of the shad runs beyond the limits of presently available data. I y'

In ' the analysis of impact of entrainment, only the egg stage was l considered entrainable in the intake. This assumption is '

,strongly supported by evidence that shad larvao do not occur in abundance in the free-flowing portion of the river water, that .

,they . inhabit, backwater and eddy habitats, and that, due to egg  !

.: drift, many eggs spawned above the intake location drift downstream and hatch below the location and are not susceptible l

~to entrainment as larvae. It is concluded that the analysis of impact based upon only the number of eggs entrained by the station is realistic. However, to respond to questions raised by  ;

licensing proceedings, the imposition of additional mortality of shad larvae due to entrainment was investigated.

(

_}

A quantitative evaluation of the entrainment of a proportion of the larval shad produced in the Holyoke Pool is limited by the lack of definitive data on the survival of shad early life stages j

', and their abundance in the entrained water. Assuming that the '

l survival rate for spawned eggs to the larval stage is 0.9, which

! was also assumed by Watson (1970) for Holyoke Pool shad, the q i effect of entraining a portion of the larvae c?n be estimated.

i 1 Although few larvae are anticipated to be entrained,. it was l

conservatively assumed, for purposes of demonstrating the effect i . of larvae entrainment, that the number of larvae entrained was l  ! equal to the number of eggs entrained. Using egg entrainment '

estimates for 1974 and 1975 as a basis for the number of shad

!l larvae entrained, the resultant loss of additional adult shad from the spawning runs due to larvae entrainment would be about 9 4

j and 20 fish, respectively.

Entrainment of large numbers of shad larvae is not expected, j

] , based on historical evidence on the abundance and distribution of

shad larvae in the Holyoke Pool. However, the above analysis

. indicates that entrainment of a high number of shad larvae may be 1 incurred with little resultant effect on the population.

1 l Shad egg entrainment losses were also evaluated for the shad runs i in 1976 and 1977. Data generated from the 1976-1977 spawning runs were reviewed, and it was determined that no changes would

! occur in the impact conclusions developed from the 1974-1975 egg j data and historical shad data on the Holyoke Pool. Some

differences did, however, occur between the 1976-1977 data and l . previous information on shad runs in the Holyoke Pool.

1

! The major difference that occurred was that the shad runs into l the Holyoke Pool were greater in 1976 and 1977 than in any other year. This resulted in total egg production for the pool being j greater than in previous years. Because of this, it is expected that had the intake been operating, more shad eggs would have

been entrained in 1976 and 1977 than in 1974 and 1975. To i evaluate the significance of this increased entrainment, the 1976 ,

and 1977 data were evaluated using the analytical techniques used 1

, in the 1974 and 1975 analysis.

t

! The entrainment estimates for 1976 and 1977 are not available j from actual field sampling at the intake location; however, i

estimates of the total number of shad eggs spawned in Holyoke l Pool are available CRusso 1976 and 1977).

Assuming the same

proportion of Holyoke Pool shad eggs are entrained in 1976 and 1977 as were estimated to be entrained previously (0.036 percent) , it is estimated that 1.4 x 107 and that 9.4 x 106 shad

, eggs would have been entrained in the years 1976 and 1977,

7 ... respectively. Assuming the survival estimate of 0.001 percent

data, this would equate to the loss of less than 150 adults-for 1976 and about 97 adults in 1977, using the ' equivalent:' ' adult .- ' ':

['l s.

model. Even if the percentage of the shad eggs-spawned above the intake location increased several fold, the losses estimated from

, 1976 and 1977 data would still represent only a small. fraction-of-- ;

! the sport and commercial fishery catch or of the' . total:. spawning l run in the Connecticut River. f ,,

In summary, the effect of entrainment of shad by the operation of the Montague Nuclear Power Station will be to . increase the mortality of the early life stages. Assuming the egg entrainment estimates for 1974 and 1975 are representative,'an ' average of only 0.036 percent of the eggs spawned in the Holyoke Pool will be entrained. Using the number of eggs entrained in those years and the estimated survival of shad eggs to adult shad,11ess than 20 adult spawning shad would be removed from the- population.

Even considering the instance when survival may.be'several fold higher than expected or when the shad run is larger than in 1974 or 1975, the estimates of entrainment effects are considered negligible when compared to the total population,of shad .~ in the Connecticut River or in the Holyoke Pool, and the number of individuals removed from the spawning run would be considerably less than the observed year-to-year variation in the shad ,

population in the river. Therefore, it is expected that the  !

operation of the Montague Nuclear Power Station will not have a I large adverse effect on the shad population.

1975 SAMPLING INTERVAL ANALYSIS l l

l The 1974 shad egg study was designed to obtain data on the i distribution and abundance of shad eggs in the vicinity of the proposed intake and discharge structures. These data also provided a quantitative basis for impact assessment of the

Montague Nuclear Power Station on the American shad. The 1975 studies are designed to gather similar data as were collected in 1974 and to study additional aspects of shad spawning behavior.

Because the 1975 studies required additional field and laboratory effort, an analysis of possible sampling frequency reduction was made.

Examination of the 1975 study design indicated that sampling every other night would provide an efficient utilization of manpower and still allow all facets of the study to be included..

To assure that such a reduction in sampling frequency would. not affect the reliability of results of the 1975 study, an analysis was made of the 1974 shad egg density data. (A brief description of the 1974 study is presented in Section 6.1.1.2.3 of the Environmental Report). This analysis compared shad-egg distribution and abundance data collected on even sampling days, odd sampling days, and all sampling days from June 5 through June 24, 1974.

Analyses of variance were performed to tesu for significant differences in mean egg density due to spatial and temporal factors. The factors were time (day) , location (east, middle, west) , position (1,2,3) , and depth (surface, niid-depth, off-bottom).. Results, using no transformation, square root transformation, and logarithmic transformation of data, are given in Tables A-1, A-2, and A-3 for even sampling days, odd sampling days, and all sampling days combined, respectively. The results indicate that, with all sampling schemes (daily and alternate day), differences in egg densities due to time, location, position, and depth are significant. The similarity of the test results indicate sampling on either a daily or an alternate-day schedule is sufficient to determine the effects of these spatial and temporal factors on egg density.

An analysis was made of the precision of daily versus alternate-day sampling using a two-stage sampling design described in 3 Cochran's Sampling Techniques (1963) , pp. 270-326. The precision I of the overall sample average number of organisms per cubic meter t in estimating the true average was calculated for daily and l alternate-day sampling programs.

0.05 0.15 0.31 0.10 0.13 0.26 To interpret the results, using alternate-day sampling, the sample mean will be within 31 percent of the true mean in 95 percent of the samples collected. It is believed that the i precision of alternate-day sampling will be adequate to describe shad-egg abundance and to assess impact of the Montague Station.

An unpaired t-test was also used to analyze mean egg density for even, odd, and all sampling days. The entire data set (all transects) and the Position 2 data set (Transect 2 only) were compared for even, odd, and all sampling days (Table A-4) .

Results indicate no significant differences at the one-percent ,

level for all comparisions. This indicates that the annual mean density of shad eggs can be calculated based upon a daily or an alternate-day sampling frequency.

These analyses indicate that similar results and conclusions regarding shad-egg distribution and abundance are obtained from the 1974 shad study using either the daily sampling schedule or the alternate-day sampling schedule and that alternate-day sampling in 1975 will provide an adequate estimate of shad-egg density.
