p SUFDIARY

1. Ichthyological Associates, Inc. conducted an ecological survey of the Delaware River in the vicinity of Point Pleasant, Pennsylvania from July 1972 through December 1973. This report describes the findings of the survey.

2. The study was initiated because a water intake associated with the proposed Limerick Generating Station will be located at Point Pleasant and will divert water from the Delaware River to the East Branch Perkiomen Creek. A portion of the supplemented Perkiomen Creek flow will be utilized by the nuclear station during periods of low (less than 560 cfs) Schuylkill River flow. This ecological survey was directed at two groups of organisms that will be affect-ed by the Point Pleasant intake: fishes and macroinvertebrates.

3. The study area includes approximately 2.8 mi of the Delaware River near Point Pleasant. Here the river averages about 550 ft in width and raages to approximately 12 ft in depth.

4. Hurricane Agnes caused a flood in late June 1972, and a second flood occurred in late June 1973. Results obtain~ed in this survey may be indicative of post-flood recovery periods rather than normal condi-tione.

5. A sampling program for fishes was established in August 1972. Seines,

},

frame trap nets, and fyke nets were used on a regular basis. ,

6. Invertebrates were sampled qualitatively in June and September 1972.

l Invertebrate drift studies were carried out in August 1972 and in July through October 1973.

7. In 1972, a total of 6,215 fishes of 37 species was taken by all gear used regularly and electrofishing. All of the 37 species were col-1ected by the combined use of seines and fyke and trar nets; electro-fishing yielded no additional species. In 1973, a total of 6,931 specimens of 41 species was collected by all sampling gear.

8. Seining yielded 5,605 specimens of 28 species in 1972, and satinfin shiner (approximately 70% of the catch), swallowtail shiner (10.07.),

and spottail shiner (5.3%) were the most abundant species. Seine collections in 1973 yielded 6,475 specimens of 32 species. Satinfin shiner (55.07. of the catch), swallowtail shiner (17.3%), and spottail shiner (5.3%) remained the most abundant species.

9. A total of 529 specimens of 24 species was taken by fyke net and trap net in 1972. The four most numerous species were pumpkinseed (21.07. of the catch), brown bullhead (20.6%), bluegill (14.7%), and redbreast sunfish (11.3%). In 1973, 456 specimens of 22 species ,

were taken in 101 collections; redbreast sunfish (24.6% of the catch),

brown bullhead (18.9%), pumpkinseed (14.3%), and white catfish (8.8%)

were the most abundant species.

10. The results of the invertebrate sampling indicate the presence of a a

relatively healthy benthic fauna. All major orders of insects were represented in the benthic samples obtained in 1972. Of the insect

h 3

orders, Diptera was represented by the greatest number of families (6) and genera (14). Chironomidae was numerically the most abun-dant family and comprised 67.37. of the total number of invertebrates taken in September 1972. Collections of 1973 have not yet been ane-lyzed.

11. The invertebrate drif t of August 1972 was dominated by surface drifters, most of which were adult chironomids. Chironomidae larvae and pupae were the largest components of the subsurface drift.

Baetidae was the second most abundant family in the subsurface drift.

O INTRODUCTION Ichthyological Associates, Inc. conducted an ecological survey of the Delaware River in the vicinity of Point Pleasant, Pennsylvania from July 1972 through December 1973. This study was one facet of the ecolo-gical investigations underway in the vicinity of the proposed Limerick Generating Station near Pottstown, Pennsylvania. Philadelphia Electric Company is constructing the nuclear station and is financing the envi-ronmental studies.

The two unit nuclear' station will utilize wet cooling towers that will evaporate an average 54 cfs of water. Current allocations to down-stream users of nearly 500 cfs of Schuylkill River water necessitate an alternative water source during periods of low (less than 560 cfs) flow.

Present plans are to withdraw consumptive water from Perkiomen Creek at Graterford, Pennsylvania (Figure 1) during periods of low Schuylkill flow. Perkiomen Creek will be supplemented as necessary by water divert-ed fro.a the Delaware River at Point Pleasant. The Delaware River Basin Commission (1973) has issued a final environmental statement on the Point Pleasant Diversion Project in which the primary impacts on Delaware River aquatic life were identified as effects due to entrainment and impinge-n nu. 1hese impacts are expected to be minimal because of the small vol-S ume of water to be withdrawn. In addition; few screenable fishes should be impinged on the intake screens for two reasons: (1) water velocities 1

3*

at the screens should not exceed 0.75 ft/sec; (2) the upriver-downriver escape of fishes will be provided for.. The entrainment of surface-drift-ing macroinvertebrates could be minimized by the installation of a float-ing log boom.

l This ecological survey was directed at two groups of organisms that l

will be affected by the Point Pleasant intake: fishes and macroinverte-brates. The purpose of this report is to describe the findings of the ecological survey for the period July 1972 through December 1973. Normal conditions may not be indicated due to extensive scouring by the flood waters of June 1972 (Hurricane Agnes) and June 1973.

DESCRIPTION OF. STUDY AREA The Delaware River st'udy area extends upstream approximately 1.25 mi from Tohickon Creek to Prahl's Island and downstream approximately 1.5 mi below Tohickon Creek to Bull's Island (Figure 2). The river averages ap" ,

proximately 550 ft in width and has a gradient of approximately 4.5 ft per mile. Water depth ranged to about 12 ft. As measured at Rigleysville, New Jersey (approximately 20 mi upstream), river flow for the interval 1906 to 1962 averaged 11,190 cfs with a maximum of 340,000 cfs on 19 Aug-ust 1955 and a minimum of 870 cfs on 20 September 1908 (Busch & Shaw 1966).

Diurnal fluctuations in flow at low and medium flow conditions were also reported by Busch & Shaw (1966) and were attributed to patterns of water use by power plants on tributary streams. These fluctuations are modified by controlled release of water from several storcge lakes and reservoirs.

There is a variety of river habitats, i.e., riffles, rapids, runs, pools, and backeddies in the study area. Substrate in the riffle and run areas is composed largely of bedrocks, boulders, and coarse gravel. Silt a

was found on the bottom in pools and backeddies. A mixture of rubble, gravel, and sand occurred along the Pennsylvania shore which tended to be 1

shallower than the New Jersey shore. Tohickon Creek is the only sizable tributary that enters the study area.

Periphytic diatoms and filamentous green algae, mostly Cladophora, appeared to be the dominant primary producers. Growths of these organ-isms, which were judged light to moderate in comparison to algal growth in the nearby East Branch Perkiomen Creek and Schuylkill River, covered the rocks in shallow riffle and run areas. Myriophyllum was the most frequently observed rooted aquatic plants in the study area, being par-ticularly common in the backeddies. The light growths of these plants may have been due to the scouring effects of the June 1972 and June 1973 floods.

Broadfoot, Powell, and Mertz (1969) and Betz Laboratories, Inc.

(1970) have studied the physicochemical characteristics of the Delaware River in the vicinity of Tohickon Creek (Table 1). We measured selected water quality parameters, i.e., dissolved oxygen, pH, and temperature during this survey. These three studies indicated that dissolved oxygen was generally close to saturation, pH ranged from 6.5 to 9.5, and temp-erature ranged from 30 to 84 F. Plant nutrient levels were higher than those found in unpolluted streams but not so high as those found in heavily polluted streams.

MATERIALS AND METHODS Physicochemical Analyses 4

Selected physicochemical parameters were measured at the tima of fish and macroinvertebrate sampling. Temperature, pH, and dissolved j

oxygen determinations were made with standard field thermometers, Hach pH indicator (Model 17-F and 17-N), and by the azide modification of the iodometric method (Winkler method), respectively. These data are not presented separately but are summarized in Table 1 and tabulated with the fish collection results by date in Tables 8 through 33.

Fishes Field surveys made in July and on 1 August were conducted to locate suitable collection statio~ns and to assess the relative effectiveness of seine, electrofishing gear, trawls, and two types of trap nets. Seines (8 to 10 ft long), fyke nets, and frame trap nets were used with repeated success. A 25-f t bag seine proved too unwieldly in the river current and on the varying substrates; therefore, its use was discontinued. Electro-fishing was used on one occasion and discarded in favor of ' seining. Sam-pling in midriver was attempted with a 9-ft semi-balloon trawl. This technique was abandoned because boulders repeatedly hung and ripped the trawl.

Seine stations and net sites were established af ter 16 August and were sampled approximately twice monthly for fishes (Figure 2). The sam-ole stations are described in Table 2. One seine collection was made at 1 each seine station, and fyke and trap nets were fished for approximately 24 hr during each 2-day sampling period. High water sample stations were

\

established when high flows made sampling at original stations impossible.

The high flow stations were seine site T40 which replaced seine sites T20 and T30, and seine site T75 which replaced site T60. Net sites T40 and

_ _ _ _ _ _ _ _ _ _ _ _ _ _ i

8 T70 were fished at high flows exclusively. Sampling at net site T45 was suspended during high river flows.

l Seines were used to collect small fishes in the shallow (to 3 ft deep) habitats. The seines were 8 to 10 and 25 ft long by 4 ft deep and constructed of 1/8- and 1/4-inch square mesh, respectively. Efforts were made by the seine crew to sample all availabic habitats at each sampling i station. The amount of fishing effort or sampling time spent at each site on each date was comparable. Seine hauls were subsampled when large numbers of specimens were captured.

Frame trap nets consisted of two rectangular, 3 by 6-f t metal frames, followed by a series of four, 2.5-f t diameter metal hoops, all enclosed by 0.5-inch mesh netting. A 3 by 50-f t leader extended from the body of the net to the shore. Fyke nets were constructed by the attachment of two, 3 by 25-ft wings and a 3-ft square metal frame mouth to a standard hoop net. The mesh size was 1-inch square and allowed most fishes less than 80 mm to escape. The wings were usually set at a 60 to 90 degree angle de-pending on the area in which the nets were set. Physicochemical data were obtained at each site when the nets were set as well as approximately 24 hr later when the nets were pulled and the catch removed.

Collected fishes were processed and released whenever possible.

3 Specimens to be retained for laboratory analysis were preserved in 107.

formalin immediately upon capture. At the laboratory all specimens were

' rinsed in water to remove the formalin and stored in 40% isopropanol or

1. discarded. Fishes were identified to species, and fork lengths were meas-4 ured to within 5 mm intervals from 0 to 100 mm and to within 10 mm inter-vals for lengths greater than 100 mm.

9 Macroinvertebrates A qualitative sampling program was initiated in July 1972 to deter-mine the species composition and relative abundance of benthic inverte-brates in the study area. Samples were taken in July and September from shallow riffle areas and along the edges of deep runs and pools. Most of the invertebrates were taken by kicking up the substratum and collect-ing the dislodged organisms in a dip net. Some of the species not sus-ceptable to dip netting were picked by hand from submerged rocks, logs, and rooted aquatic plants.' The' specimens were preserved in 957. isopro-panol immediately upon capture.

In the laboratory, the animals were removed from the sediment and identified, when possible, to genus or species. The following references were used for identification:

An additional study was carried out to estimate several drift para-meters, including composition, diurnal periodicity, and numbers and bio-mass per unit volume. On 16 August 1972, two macroinvertebrate drift nets (0.5 mm mesh) were set side by side (2-ft separation) in the riffle located approximately 220-yd upstream of Tohickon Creek. Each net was

35. inches in length and was held open by a 1-ft square aluminum frame.

Each frame was fitted with a Plexiglas apron which tapered to a 3 by 12-inch opening. The aluminum frame was attached to two pieces of 1.6-inch aluminum conduit. This arrangement allowed easy placement and removal of the net over steel rods which were hammered into the substrate. The two nets were placed in the river for a 1-hr interval every 2 hr for 24 hr.

Each net projected 0.5-inch r.bove the water surface and extended 11.5 inches down the water column. The collection of samples every 2 hr en-abled the monitoring of any temporal changes in drift parameters which occurred during the 24-hr period.

?

The material collected in the nets was washed into jars and preserved

~

I g in 95% isopropanol. The aquatic component of the drif t was identified to 1

} family. All organisms were counted, dried in an oven at 60 C for 72 hr, and weighed to the nearest 0.1 mg. $

i 11 Estimates of the mean numbers and weights of drif ting invertebrates per unit volume of water sampled were er Iculated for the 24-hr drift study. Flow (f t /sec) through the samplers was calculated as the prod-uct of the cross-sectional area sampled (f t ) and the velocity of water entering the samplers (f t/sec). Water velocity was measured at the en-trance of each sampler with a Gurley Model 625 current meter.

The average number and weight of invertebrates per cubic foot of water sampled was calculated from the generalized formula D,

D= y s

where D = average number or average weight per cubic foot of water, D, =

number or weight of invertebrates that would have been collected if the net sampled continuously for 24 hr, and V, = volume of water that would have passed through each sampler in 24 hr. Since the drift' samplers sam-pled I hr every 2 hr for 24 hr, it was necessary to estimate D, by summing the area under the curve relating either numbers or weights per sample to I

the time the sample was taken.

During July . ugh October 1973, monthly macroinvertebrate drift sampling was carrieu out. Two nets were placed in the river for 1 hr ev-l ery 2 hr between 1800 and 0200 hr, the period in which peak drift rates j were expected. These samples have not yet been analyzed.

RESULTS Fishes f

A total of 6,215 specimens of 37 species was taken by the various gear in 1972; the 1973 catch was 6,931 specimens of 41 species (Table 3-7). Most species were captured by seine, particularly minnows (Cyprin-idae) and young of the year fishes. Larger fishes, primarily game and pan species of the family Centrarchidae, were captured with fyke and frame trap nets. All of the 37 species taken in 1972 were collected by the combined use of seines and fyke and frame trap nets; electrofishing yielded no additional species. The presence of two anadromous species, alewife (Alosa pseudoharengus) and American shad (Alosa sapidissima) is well documented (Miller et al.1972 and Mihursky 1962), but we took none with our gear until 26 June 1973 when we collected four alewife at site T40. We collected no additional alewife and no American shad.

Seine collections yielded 5,605 specimens of 28 species in 1972 (Ta-ble 4) and 6,475 specimens of 32 species in 1973 (Table 5). Satinfin shiner represented nearly 70% of the seine catch in 1972 and 55.0% in 1973; it was consistently the most abundant species taken by seine after 1 August in both years. Swallowtail shiner (10.0% of the 1972 catch and 17.3% of the 1973 catch) and spottail shiner (5.3% in 1972 and 1973) were the only other species that comprised greater than 5.0% of the catch.

Other species that commonly entered the seine catch were common shiner, 1

spotfin shiner, redbreast sunfish, blacknose dace, pumpkinseed, bluegill, tessellated darter, banded killifish, and golden shiner. In general, the number of species taken by seine decreased from August to December. This j

13 4

l trend was probably due to the migration of young of the year fishes out of the shallow water along shore as well as the inability of the collec-tors to sample as cfficiently during the higher December flows.

Intersite differences in seine catches occurred and appeared to be due to habitat differences. Seine site T60 was the most productive seine station in terms of the number of species and specimens collected (Tables 8-33). In general, the other seine sites yielded similar, but lower catches. The higher productivity of site T60 seemed to be due to the greater variety of habitats that were present. Also, sizable sheltered areas were available; the site was not as open and exposed to the river current as the other sites.

Forty-eight trap net and fyke net collections in 1972 yielded 529 specimens of 24 species (Table 6). The four most numerous species were pumpkinseed (21.0% of the total catch), brown bullhead (20.6%), bluegill (14.7%), and redbreast sunfish (11.3%). No other. species comprised great-er than 5.0% of the total 1972 catch. Other pan and sport fishes commonly taken (i.e., comprising over 2.0% of the catch) were white catfish, white perch, rock bass, black crappie, and American eel. Chain pickerel, wall-cye, and muskellunge were each represented by only a single specimen.

In 1973, a total of 456 specimens of 22 species was taken in 101 col-s lections (Table 7). Redbreast sunfish (24.6% of the catch), brown bull-head (18.9%), pumpkinseed (14.3%), and white catfish (8.8%) were the most fabundantspecies. White perch, bluegill, black crappie, American eel, rock bass, and green sunfish were also common. One specimen each of the t.alleye and muskellunge were again taken.

D 14 l

During the survey period, no appreciable dif ference was observed in l

l the fyke net catch versus the trap net catch (Tables 8-33). Fishes were more frequently captured at net sites T25, T35, and T60 than at any of other net sites. These sites were situated in similar habitats, i.e.,

backeddy or cove areas of moderate (3 to 8 ft) depth.

Benthos Representative species of all major orders of aquatic insects were found in the benthic samples; oligochaets, molluscs, and crustaceans were also well represented (Table 34). Of the insect orders, Diptera (true flies) was. represented by the greatest number of families (6) and genera (14). The most diverse family of Diptera was Chironomidae (midges) which was represented by eight genera. Trichoptera (caddis flies) was the second most diverse order with representatives of six families and 10 gen-era. Of the Trichipteran genera, Hydropsyche (uet ceddis flies) was the most diverse with nine species. Ephemeroptera (may flies) and Coleoptera (beetles) were the third and fourth most diverse orders with four families and 11 genera and four families and eight genera, respectively. Only one species of Plecoptera (stone flies) was taken.

Chironomidae was numerically the most abundant family and comprised 1

67.3% of the total number of invertebrates taken in September 1972 (Table 35). The most numerous genera and their percentage of the total September y collection are given in Table 36. Note that Rhagovelia, a small water strider, was included among the 15 most abundant genera. This is probably an incorrect placement since all Rhagovelia were taken on the surface in an isolated backwater area with a single sweep of the dip net.

Our sampics were taken less than 3 mo af ter the major flood of 22-23 June 1972 and, therefore, may be characteristic of a post-flood recovery phase rather than the normal July through September fauna. This present list of taxa probably includes most of the relatively abundant species.

However, further samples will have to be taken before a definitive species list can be compiled and seasonal changes in relative abundance can be described.

(

The results of our sampling to date indicate that the presence of a relatively healthy benthic fauna; one which would be typical of a clean or mildly polluted warm-water stream in this part of the United States.

Invertebrate Drift The two drift nets collected 28,145 invertebrates during the 24-hr study interval in August 1972. Since the nets sampled for 'only 12 of the 24 hr, the above value represents spproximately,507. of the total number that would have been captured had sampling been continuous. The bulk of the drif t was composed of surface drifters (21,212 individuals), most of which were adult chironomids. The subsurface drif t consisted of individ-uals froca 21 families (Table 37). Chironomidae larvae and pupae were the largest components of the drif t and composed 23.1 and 70.07, of the total l number, respectively. Baetidae was the second most abundant family (5.2%)

in the subsurface' drif t; no other family comprised more than 1.07 of the total.

Peak drif t rates occurred early in the evening for both' surface and subsurface drifters (Figure 3). These peaks appear to have been caused by

an emergence of Chironomidae rather than a behavioral diurnal periodicity in drift. Note that Chironomidae pupac were responsible for mos t of the dici fluctuation in subsurface drif t (Figure 4) and that their drift rate began to increase early in the afternoon. Surface drift followed a simi-lar pattern (Figure 3) with the peak rate occurring 2 hr later in the evening. This pattern would be expected if the pupae were emerging and the new adults were directly influencing the level of surface drif t. This hypothesis was supported by our analysis of the surface drift which re-vealed that over 90% of the surface drif ters were adult chironomids.
