SUMMARY

This report presents the results of impingement abundance studies conducted q during 1987, as required by the State Pollutant Discharge Elimination System (SPDES) Permit No. NY 302 0109, Section 11 (dated 1 November 1985) for the James A. FitzPatrick Nuclear Power Station.

Impingement abundance was monitored between 3 and 20 days per month, for a total of 76 samples in 1987.

Impingement sampling at JAF during 1987 resulted in the collection of 53,302 organisms. The collection was categorized into 35 fish taxa; of the 35 taxa, 1 was identified to tamily, 1 vas identified to genus, and the remaining 33 vere identified to species. Two invertebrate taxa (crayfish and clam) vere also represented in the 1987 samples. An amphibian, Necturus sp., was col-lected in April. Alevife was the most numerous species (33,569), comprising 63 percent of the total catch. Alevife, rainbow smelt, spottail shiner, and trout-perch accounted for 78 percent (51,993) of all fish collected (53,200).

1. INTRODUCTION The James A. FitzPatrick Nuclear Power Station (JAF) is located on the shore of Lake Ontario approximately 11 kilometers (7 mi) northeast of the City of Oswego, New York. JAF is an 821-HVe boiling vater reactor.

The water intake structure is located near shore in approximately 7.3 meters (24 ft) of water and the discharge, with a 236-meter (774-ft) diffuser, located offshore in approximately 9.1 meters (30 ft) of vater.

Vater entering the intake flows through trash racks, which are spaced approxi-mately 7.5 cm apart and used for removing large items, such as logs, and then through 9.5-mm mesh traveling screens, which are used for screening out smaller

~

materials. Periodically, the traveling screens are rotated and vashed to remove any accumulation of impinged organisms or other material which empties into a sluicevay and then into an impingement collection basket. Impingement of aquatic organisms at JAF has been monitored yearly since 1975 in order to estimate species abundance and composition. The composition of the impingement collections has ranged from 26 to 54 fish species per year. Alevife and.

rainbov smelt generally have been the most abundant fishes in the impingement collections. Other fishes which have been found in relatively large numbers in the impingement collections include: white perch, gizzard shad, trout-perch, spottail shiner, and tessellated darter.

This report presents the results of impingement abundance studies conducted during 1987 as required by the SPDES Permit No. NY 002 0109,-Section 11 (dated 1 November 1985) for JAF.

Impingement abundance was monitored between 3 and 20 days per month, for a total of 76 samples in 1987.

As required.by correspondence from the New York Pover Authority (NYPA) to the Nuclear Regulatory Commission (NYPA 1981, personal communication), all impinge-ment samples are checked for the presence of the Asiatic clam (Corbicula sp.).

No Corbicula sp. molluscs vere found in the 1987 impi.gement collections.

2. METHODS AND MATERIALS l

l 2.1 SCHEDULE (PERMIT SECTION 11.B.1) l L In accordance with permit Section 11.B.1, impingement collections vere scheduled for 78 days between 1 January and 31 December 1987 (Table 2-1).

Stratified random samples vere collected over a 24-hour period. Sample dates vere scheduled such that no more than 10 days occurred between samples. Table 2-2 lists the scheduled sampling dates.

Because JAF vas shut down for scheduled refueling and maintenance from 15 January to 30 April 1987, only 76 of 78 impingement samples were success-fully collected. During that time, 6 sampling dates had to be rescheduled.

On two of these sampling dates, impingement collections could not be obtained or rescheduled due to maintenance work (Appendix A). On three other dates, sampling was rescheduled due to maintenance or veather problems, and success-fully completed (Appendix A).

2.2 SAMPLING PROCEDURE (PERMIT SECTION 11.B.2,3,4,5)

All sampling procedures vere accomplished according to Standard Operating Procedures (SOPS) (NYPA 1985). Samples vere initiated around 1300 hours0.015 days <br />0.361 hours <br />0.00215 weeks <br />4.9465e-4 months <br /> of the sampling day. Before sample collection, the traveling screens were rotated and vashed for 15 minutes, after which the collection basket, with a 9.5-mm (3/8-in.) stretch mesh liner, was positioned at the end of the sluicevay. The collection basket remained in place for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, unless high impingement or debris loads required that it be emptied, in which case it was removed, emptied, and repositioned.

Cooling water flow rates, intake and discharge temperatures, and power production vere obtained for each sample date (Appendix B).

A subsampling routine vas utilized for occasions when high impingement rates or high debris loads vere encountered. The subsampling technique was based on volume, and the total 24-hour catch vas estimated using the formula:

Estimated No. of Fish = Volume of Total Sample x No. of Fish in Aliquot in Total Sample Volume of Subsample The volume of the total sample vas determined by repeatedly filling a volume-trically graduated container, recording the values, and adding them. The total volume was thoroughly mixed by hand or with a shovel and spread out evenly over a flat surface. An aliquot (s) of the total sample vas randomly selected and

! this portion of the sample was removed and measured to determine its volume, f During 1987, subsamples constituted at least 25 percent by volume of the total sample. The fish in the subsample vere then processed according to regular laboratory procedures (Section 2.3). ,

2.3 LABORATORY PROCESSING (PERMIT SECTION 11.B.4)

The impingement sample was returned to the laboratory where all organisms were sorted, identified, and enumerated. Identification was made to the lovest possible taxonomic level, which was usually species. A list of common names and their associated scientific names is included in Appendix C.

t A maximum of 25 individuals of the following fishes were.veighed and measured: l vhite perch, alevife, rainbow smelt, smallmouth bass, yellow perch .and each '

species of salmonid. Other fishes vere enumerated and weighed to obtain a total' count and total veight for each species or taxonomic level.

Total lengths were measured to the nearest millimeter (mm). In this report, 100 mm was used as a cutoff between young of the year and older fish based on length at-age information in Scott and Crossman (1973).

Veights were measured to the nearest: 0.1 gm for specimens less than.10 gm, 1.0 gm for specimens between 10 and 2,000 gm, and to the nearest 25 gm for specimens.over-2,000 gm. Specimens with any unusual conditions, abnormalities, or presence of fish tags vere noted on the data sheets.

2.4 VATER QUALITY DETERMINATIONS (NYPA 1985)

. Intake and discharge temperatures vere measured at the beginning and end of

- each impingement sample. Intake temperature was measured in front of the trash bars. Discharge temperature was measured in the discharge canal. Intake and

,' discharge temperatures (+0.5 C) vere determined from a bucket of water retrieved at each location using a thermometer. Thermometers vere calibrated bimonthly according to the SOP. Intake and discharge temperatures vere also recorded from the plant operational log on sample days.

2.5 DATA' PRESENTATION (PERMIT SECTION 11.C.3.a)

Data are presented according to the requirements set forth in the SPDES permits

a. Monthly and annual total of impingement by species and grand total over all species.

b. Monthly "mean" is equal to the total number of fish impinged by species on all sampling days in a given month divided by the total number of sampling days.

c. Total estimated impingement for each month was calculated using the formula:

D= c (x) v where D = total estimated impingement c . the number of fish collected during the sampling period v the volume of cooling vater used during the sampling period x - the total monthly volume of cooling vater used.

The annual impingement estimate vas then calculated by adding the 12 monthly impingement estimates.

5 2-4 c

e

d. Additional tables vere calculated for mean daily impingement rate (total number of fish impinged by species on all sampling days in a month divic'ed by the total number of sampling days) and a monthly estimated impingement based on rate (mean daily impingement rate multiplied by the total number of days in a particular month) and are

! available for comparison of data presentation methods.

e. Monthly and annual totals of biomass (grams) by species and grand totals over all species, t

f. Total estimated biomass (adjusted for flov) vas calculated in the same manner as estimated impingement.

2.6 COLLECTION EFFICIENCY (PERMIT SECTION 11.C.3.b)

To assess the efficiency of the traveling screens in removing impinged l- organisms from the circulating vater intake system, a collection efficiency study approved by the New York State Department of Environmental Conservation (NYSDEC) (21 August 1986 letter from D. Dunning to E. Horn) vill be conducted at JAF.

3. RESULTS AND DISCUSSION ,

3.1 IMPINGEMENT .^.BUNDANCE AND COMPOSITION (PERMIT SECTION 11.C.3)

Impingement sampling at JAF during 1987 resulted in the collection of 53,302 organisms composed of 2 genera of fish, 32 species of fish, 2 invertebrate taxa (crayfish and clam), and 1 amphibian taxon (mudpuppy) (Table 3-1).

Highest species diversity occurred in November (21 species) and December (19 species). The lovest diversity occurred in February (5 species) and March (2 species) when JAF vas shut down for refueling and maintenance.

Alevife was the most numerous species, comprising 63 percent of tha total catch, followed by rainbow smelt (33 percent). White perch, smallmouth bass, yellow perch, and four species of salmonids (chinook salmon, lake trout, rainbow trout, and Atlantic salmon) vere collected in lov abundance impingement samples at JAF.

Rainbov smelt vere collected in every month during 1987. While alevives vere collected in 10 months, white perch and smallmouth bass vere collected in 8 months, and yellev perch vere found in samples collected in 5 months of 1987.

The four salmonid species were distributed in the 1987 impingement collections as follovs: chinook salmoa, 4 months; lake

• out, 3 months; and rainbov trout and Atlantic salmon, 1 month each.

Rainbov smelt dominated impingement samples in January (96 percent), February (91 percent), April (58 percent), August (68 percent), September (64 percent),

October (86 percent), and December (72 percent). Alevife dominated the impingement in May (84 percent) and July (81 percent). In June and November, the distribution of rainbov smelt and alevife vere more equivalent with neither species dominating the impingement samples.

As in previous years, high impingement at JAF during 1987 occurred when strong vinds from the vest or northwest resulted in heavy vave action. In January, 5,364 young-of- the-year (YOY) rainbov smelt vere collected. Of those, 72 oercent vere collected during the sample collection period on 13-14 January 1987 when vinds vere from the northwest to vest at from 15 to 25 knots and vaves vere from 0.6 to 1.2 m (2-4 ft). For the 24-hours preceding the impingement sample (12 and 13 January), vinds vere from the vest and northwest at from 15 to 30 knots and vaves were 1.8 to 2.4 m (6-8 f t). YOY rainbov smelt

, were also collected in higher numbers in December 1987. The December abundance

- peaked during samples collected on 16-17 and 21-22 December 1987. During 16-17 December, vinds were from the vest to northwest from 25 to 40 knots and vaves vere from 1.2 to 2.1 m (4-7 ft). Twenty-four hours previously (15 December),

the vinds had shifted to the northwest from the southeast at 45-50 knots and waves vere from 2.4 to 3.7 m (8-12 ft). During 21-22 December, when similar conditions occurred, vinds vere 25-35 knots from the southwest and vaves vere from 1.2 to 3.0 m (4-10 ft). The impingement abundance total for both samples vas 81 percent of the monthly impingement for rainbov smelt and 71 percent of the December impingement total for all species.

4 LiftonandStorr(1977)'foundstatisticallysignificantcorrelat(onsbetween vave height, vater temperature, and vind action, and impingement at power plants on Lake Erie and Lake' Ontario. Vave height was the most significant ,

factor contributing to the correlation. They hypothesized that vave induced J

turbulence and possibly turbidity interfere with a fish's normal ability to detect and avoid an intake structure, resulting in a higher impingement.

Impingement abundance increased in April and May, corresponding to the migrations of alevife and rainbow smelt inshore to spawn. However, the numbers I of fish impinged at JAF vere lov from 16 January through 30 April 1987. due to  !

a refueling and maintenance outage during which the main circulating vater pumps were shut down for extended periods (Appendix B). The reduction in vater through the intake reduced impingement. When an outage occurs'during the spring. months as many species of fish like alevife and rainbov smelt are moving inshore to spawn, the impingement abundance of these species is reduced as compared to non-outage years (Section 3.5). Impingement increased during Spring 1987 due to the movement of large numbers of fish past the intake during the offshore-onshore spawning migrations. Alevife and rainbow smelt exhibited high post-spawning mortalities (Scott and Crossman 1973; Lifton and Storr 1977). The same stresses that induce high mortality also make the fish more vulnerable to impingement (Lifton and Storr 1977).

Impingement abundance decreased through the summer (June and July) as adult fish finished spawning and moved offshore. The impingement rate increased in August and late fall as YOY alevife and rainbov smelt attain a size large enough to become susceptible to impingement. The predominance of YOY at this l- time is associated with the movement of large schools of YOY from their inshore nursery areas to overvintering grounds in the deeper waters of Lake Ontario, a process that brings these schools into the vicinity of the intake. YOY are L also influenced by environmental factors which periodically increase their 1

abundance in the impingement samples.

For comparison, impingement rates and abundance estimates were calculated using two different methods. The mean daily impingement rate (Table 3-2) is defined u as the average number of fish collected per sample day per month. The impinge-ment rate is defined as the total number of fish impinged by species on sampling days in the month divided by the total volume pumped on sampling days (Table 3-3).

l The mean daily impingement rate (Table 3-2) peaked in January, May, and l: December. Peaks in the daily impingement rate reflected seasonal peaks in l' impingement abundance shown in Table 3-1. The mean daily impingement rate of i alevife was highest in May (1,499) and corresponded with the period of peak impingement for the species. The mean daily impingement rate for rainbov smelt peaked in January (1,341) and December (452), also corresponding to periods of peak abundance for rainbov smelt. During January and December, the rainbov smelt vere predominantly YOY (Section 3.2). The average daily impingement rate of rainbov smelt in May was 261, which reflects the period of peak adult

'~

abundance.

The same pattern in seasonal impingement abundance vas observed when impinge-ment was expressed as the number of fish per million cubic meters (MCM) (Table l- 3-3). The rates of impingement by flow are generally lover than the daily t

o impingement rates in Table 3-2. Exceptions occur in February, March, and April when the number of fish per MCM is higher due to the refueling outage and the resulting small amounts of vater passing through the intake. Vhen outage conditions (e.g., reduced water flovs) and inshore spavning migrations coin-cided, the density of fish per unit volume can be higher as occurred in 1987.

The impingement rate Lased on flov was highest in January (865 fish /MCM), May (854 fish /MCH), and December (310 fish /MCM). These peaks corresponded to seasonal abundance trends and periodic meteorological influences on alevife and rainbov smelt as previously discussed.

I l

The estimated number of aquatic organisms impinged in JAF during 1987 was calculated based on the mean daily impingement rate (Table 3-4) and on the impingement rate by flow (Table 3-5). Estimates are similar for both methods of data expression. Impingement estimates by flov for February and March are higher than the estimates by daily average rate for the same months.

Differences may be attribu:ed to the refueling and maintenance outage which occurred during these months. The reduced water flov vould increase the i density of fish per unit volume. Any fish collected, when expressed by unit volume, vould have a higher estimated impingement than under normal operating conditions.

The total estimated number of aquatic organisms impinged at JAF nuclear power i station during 1987 based on flov vas 164,382 organisms. The estimated annual impingement of alevife was 65,959. Alevife estimated impingement was 40 percent of the total annual estimated impingement for both methods. The estimated annual impingement of rainbov smelt vas 87,462, and was 53 percent of the total annual estimated impingement. The annual estimated impingement based on flow during 1987 for additional species of note vas as follows: yellow perch, 41; white perch, 578; smallmouth bass, 284; chinook salmon, 41; lake trout, 25; rainbov trout, 8; and brown trout, 2.

3.2 LENGTH DISTRIBUTION (PERMIT 11.B.4)

Length frequency distributions are given for the following species: alevife, rainbov smelt, white perch, yellow perch, smallmouth bass, and the salmonid species (chinook salmon, lake trout, rainbow trout, and Atlantic salmon) in Tables 3-6a through 3-6f. Alevife collections vere predominated by adult /

subadults from April through July. YOY predominated the alevife collections from August through November. Adults /subadults dominated the impingement again in Decembar. Overall, the alevife measured from the 1987 impingement collections vere dominated by adults /subadults (60 percent of those measured).

The minimum length measured for alevife collected in 1987 vas 3.0 cm; the

! maximum length was 21.5 cm.

Impingement collections of rainbov smelt vere dominated by YOY fn all months of 1987 except January and May when adults dominated the impingement collection.

Of the total number measured, 71 percent vere YOY. This corresponds with U.S.

Fish and Vildlife Service (USFVS) findings (O'Gorman et al. 1988, unpublished) of a large 1986 year class recruited into the population in 1987. During

/ several months, YOY rainbov , smelt vere damaged to an extent that made it

! imposrible to accurately obtain length measurements on individual fish (e.g.,

l July, August, and September). The minimum length measured for rainbov smelt l collected in 1987 vas 3.1 cm, the maximum length measured was 21.2 cm.

l A total of 93 percent of the white perch measured vere YOY, 49 percent of which vere collected in January. The minimum length measured for white perch in 1987 was 4.0 cm; the maximum length measured was 29.5 cm.

Yellow perch vere collected primarily as subadults and adults in 1987. A total of two YOY yellow perch vere collected in impingement samples from January and May 1987. The minimum length measured for yellos perch in 1987 was 7.4 cm; the maximum length measured was 25.7 cm.

Smallmouth bass vero collected as YOY (68 percent) and adults (32 percent).

They were generally collected as individuals or in small numbers. The minimum length measured for smallmouth bass in 1987 vas 3.4 cm; the maximum length measured was 44.5 cm.

The salmonid family was represented by chinook salmon, lake trout, Atlantic salmon, and rainbow trout at JAF in 1987. All lake trout were collected as adults and ranged from 63.2 to 7L 0 cm. The chinook salmon vere collected as parr-marked young (May) and a fingecling (July). One adult chinook salmon vit collected in January. The minimum length measured for chinook salmon was 7.2 cm, the maximum length measured was 48.0 cm. Atlantic salmon and rainbov trout vere collected as adults and vere 72.1 and 43.3 cm in length, respectively.

3.3 BIOMASS (PERMIT SECTION 11.B.4)

Total biomass collected in the 1987 impingement samples at JAF vas 342.364 grams (342 kilograms) (Table 3-7). Alevife (221,459 grams 221 kilograms) comprised 65 percent of the total biomass for 1987. Rainbov smelt (44,800 grams, 13 percent), gizzt.ed shad (16,127 grams, 5 percent), and lake trout (14,473 grams, 4 percent) were second through fourth in rank, respect-ively, by veight. Combined with alevife, rainbov smelt, gizzard shad, and lake trout comprised 87 percent of the biomass of impinged fish for 1987 at JAF.

Biomass is generally more videly distributed among the species collected since a few heavy-bodied fish (basses, perches, salmonids) may veigh more than large numbers of the more fragile-bodied alevife and rainbov smelt.

The estimated biomass (calculated based on flov) vas 1,131,222 grams (1,131 kilograms) of which 50 percen: (565,767 grams, 566 kilograms) vas the estimated biomass of impinged alevife, and 165,509 grams (165 kilograms; 11 percent) was the estimated biomass of rainbov smelt (Table 3-8). Gizzard shad (123,473 grams, 123 kilograms) and lake trout (63,267 grams, 63 kilograms) comprised an additional 17 percent of the total estimated biomass. The total estimated biomass for white perch was 6,489 grams; for yellow perch 2,858 grams ana for smallmouth bass 23,746 grams. The total estimated biomass for the salmonid species was as follovst chinook salmon, 8,380 grams; rainbow trout, 9,393 grams; and Atlantic salmon 6,385 grams, which together comprised 2 percent of the total estimated biomass for 1987 at JAF.

3.4 VATER QUALITY (PERMIT SECTION 11.A) (NYPA 1985)

Intake temperatures recorded from grab samples taken during impingement sampling at JAF ranged from a minimum of 0.5 C on 30 January 1987 to a maximum 3-15

3.5 HISTORICAL IMPINGEMENT COMPARISONS (PERMIT SECTION 11.C.3d)

Impinged fish have been collected annually at JAF since 1975. Estimates (adjusted by flov) of impingement abundance for the years 1976-1987 are shown in Table 3-9. Abundance peaks generally occur in the spring and early summer as fish move inshore to spavn. This seasonal movement is primarily determined 7

by water temperature which may cause the dates of spring abundance peaks to vary from year to year. In 1987, the total number of fish impinged at JAF vas lov from 16 January - 30 April due to an extended outage during which the main circulating vater pumps vere shut down for lengthy intervals. When an outage occurs during the spring, a period when many species of fish (particularly alevife and rainbov smelt) are migrating inshore to spavn, impingement abun-dance is lover than non-outage years. This is particularly evident for 1979, 1985, and 1987 impingement estimates in Table 3-9. Impingement abundance usually decreases after adult fish finish spawning and move offshore. The summer decrease in impingement is evident in most years during June and July (Table'3-9). . Impingement abundance increases again in late summer and early fall when YOY alevife and rainbov smelt reach impingeable size.

The species composition of impingement collections at JAF has ranged from 26 to 54 fish species per year. Alevife has been the most abundant species in the impingement collections, with the exception of 1978 when threespine stickleback

]' vere most abundant, and in 1979 when rainbov smelt vere most abundant (Table 3-10). In 1987, rainbov smelt appeared first in estimated impingement (adjusted for flov), however, the actual impingement collection of rainbov smelt (Table 3-1) ranks them second in abundance. The variation in the rank is likely due to a combination of outage conditions (and the reduction in flov through the intake) and the periodic influence of meteorological factors on the methods of data expression between the two tables. Other species which have been found in relatively large numbers in the impingement collections include white perch, gizza d shad, trout-perch, spottail shiner, and darters.

f Biological factors such as population size, migration patterns, schooling, and spawning behaviors, in conjunction with environmental factors such as vater temperatures, currents, and localized meteorological conditions, can influence the number and species compo:sition of fish in the vicinity of the JAF intake.

Historically, at JAF, specific meteorological conditions such as storm activity and/or strong vinds from the vest or northwest and the resulting increase in vave action, have generally resulted in higher impingement abundance. Lifton and Storr (1977) found statistically significant correlations between environmental factors (vave height, vater temperature, and vind action) and impingement at power plants on Lake Erie and Lake Ontario. Vave height was correlated at a higher level than either of the other factors. They hypo-thesized that wave-induced turbulence and possibly turbidity interfere with a l

fish's normal ability to detect and avoid an intake structure. YOY, particu-

) larly, seem to be affected by adverse meteorological conditions and are often responsible for the abundance peaks from late fall through vinter in most years (Table 3-10).

'a Alevife and rainbov smelt exhibit definite periodic fluctuations in population size (Scott and Crossman 1973; Christie 1974; Elrod et al. 1979, 1980; 0'Gorman and Schneider 1986). Large die-offs of alevife have been reported since their appearance in the Great Lakes. According to the USFVS and the NYSDEC (Elrod

{ et al. 1979, 1980 0'Gorman and Schneider 1986; 0'Gorman et al. 1988, unpublished), the alevife population in Lake Ontario declined due to a die-off during the vinter of 1976-1977; a vinter of severe cold. Losses vere estimated as high as 60-75 percent-of the adult population, resulting in the complete elimination of the 1975 year class. Decreased impingement collections of alevife were observed at JAF for several years, through 1979. Since 1976-1977 Lake Ontario vinters have been milder than normal and there have been no catastrophic vinter die-offs recorded, although smaller die-offs have been noted, e.g., 1983 (O'Gorman et al. 1988, unpublished). The most recent die-off occurred in 1986 and appeared due to Lake Ontario's inability to sustain the unprecedented numbers of fish present in the Spring of 1986 (O'Gorman et al.

- 1988, unpublished).

Rainbov smelt have also displayed annual fluctuations in population abundance in the Great Lakes from year to year. USFVS biologists have noted yearly fluctuations in rainbov smelt abundance with high recruitment occurring in the odd years (O'Gorman and Bergstedt, personal communication 1982, 1983; 0'Gorman et al. 1988). In 1987, the rainbov smelt population experienced an exceptionally strong recruitment of fish from the large 1986 year class:

80 percent of the population vas made up of this cohort (O'Gorman et al. unpub-lished). Unusually large catches of yearling rainbov smelt were made not only in Lake Ontario but also in Lakes Superior, Huron, and Erie. According to the USFVS biologists, veather may have favored smelt reproduction since it vas a factor common to all the lakes. In 1987, the total impingement of rainbov smelt consisted of 71 percent YOY (Section 3.2), many of which vere collected in January and, therefore, vere of the 1986 year class. This data appears to correspond with the USFVS data. Overall, lakevide natural fluctuations may not be as easily discernable from impingement collection data as one might expect, since a large collection of YOY could be impinged at a time prior to their re* witment into the lake population, particularly, collections of YOY taken in tb late summer through fall of the year spawned. Annual impingement abc. dances (all months together) may appear high at a time when predictably the natural population vould be showing a decrease in overall population size.

Annual impingement abundance estimates for white perch, yellow perch, small-mouth bass, and the salmonids for the years 1976-1987 are shown in Table 3-11.

Changes in abundances are most likely attributable to natural fluctuations of

~

individual populations, intraspecific biological behaviors, plant operating conditions, and meteorological occurrences on the impingement process.

Historically, the estimated impingement abundance of selected species appears to be most influenced by extended outages as demonstrated by the numbers collected during years in which extended refueling outages occurred (1981, 1983, 1985, and 1987).

Fluctuations in population abundance appear to be attributable primarily to environmental conditions, i.e., mor-tality, spawning success, biological behavior, and' meteorology. Thus, it appears that impingement has had little effect on species composition or the.

size of fish populations in the vicinity of JAF.
