It is located on a 435-ha site in Salem Township, Luzerne County, 8 km northeast of Berwick, Pennsylvania. Commercial operation of Unit 1 is scheduled to begin in Feburary 1981 and Unit 2 in May 1982. Under terms of an agreement finalized in January 1978, 90% of the Susquehanna SES is owned by the Pennsylvania Power - * ght Company (PP&L) and 10% by the Allegheny Electric Cooperative, Inc. Ecological studies have been conducted near the Susquehanna SES by Ichthyological Associates, Inc. (IA) since 1971. The Susquehanna River, from which the Susquehanna SES will withdraw cooling water, has been investigated since the beginning of the studies, whereas terrestrial investigations of the site were initiated in 1972, discontinued in 1975, and reinstated in the spring of 1977. The overall objecti re of these studies has been to establish an ecological baseline of e cisting conditions in the river and on the site prior to operaticn of the f,usquehanna SES. Data from studies prior to 1978 have been presented in annual progress reports from 1971 through 1977 (see page 293). Throughout 1978, vari,us physicochemical characteristics of the river were analyzed, and its algal, macroinvertebrate, and fish populations were nonitored. Terrestrial investigations of the site dealt with studies of flora, vegetation, and birds. Descriptions of sampling procedures, detailed data tabulations, and interpretation of the results are present ed in this annual progress report for 1978. 1y70005 2 Most of the aquatic studies were conducted within 2 km of the intake structure and discharge diffus-r of the Susquehanna SES. The slope of the river bed in this stretch is 0.3 m/km and the average width ir about 300 m.Depth is relatively shallow in most areas (less than 2 m), but some pools may exceed 5 m even during low river flow. During periods of low flow, which normally occur in late summer and early autumn, abandoned eel walls help maintain pools, some of which are several kilometers long. In times of high flow the river level commonly increases 3 m or more, and its flow characteristics resembles an open channel. Upriver from the site, the " Wyoming Region" of the northern anthracitc coal field lies beneath or adjacent to the river. Acid mine drainages from this area, which enter from abandened strip and shaf t mines, degrade the water quality at the site (Gale et al. 1976). Terrestrial studies were done on either the site or on adjacent PP&L properties. Elevations of the site range from 150 r above mean sea level on the river flood plain to a maximum of 325 m near the northwest property line. About 40% of this land is flat and the remainder is hilly rather than mountainous. This area is located within the Ridge and Valley Section of the Appalachian Valley Province (Fenneman 1938) .

Range in river temperature was 3 from -0.1 to 30.0 C; flow from 28 to 2,172 m /s; and level from 148.21 to 152.97 m above mean sea level..sspite construction activities, data were similar upriver from the intake and downriver from the discharge. Although acid mine drainages from sources upriver continae to pollute the river at the site, analyses of physicochemical data from 1973 through 1978 revealed significantly improved water quality. The magnitude of diel fluctuations in temperature, dissolved oxygen, and pH varied seasonally. INTRODUCTION This report presents physicochemical data collected from the Susquehanna River near the Susquehanna SES in 1978. The objective since 1971 has been to establish a baseline of water quality parameters for evaluation of possible effects on the rive': as a result of the operation of the Susquehanna SES. Records of similar physicochemical data are in annual reports from 1971 through 1977 (Ichthyological Associates 1972, 1973, 1974; Smith and Soya 1976, Jacobsen and Soya 1976, 1977; and Soya and Jacobsen 1978). S70010 7 PROCEDURES Physicochemical data were collected at the Susquehanna SES Biological Laboratory and the SSES and Bell Bend sampling sites (Fig. A-1). The laboratory is on the river's west bank, 465 m upriver from the cent er of the Susquehanna SES intake structure. The SSES site is about 190 m upriver from the intake structure. The Bell Bend site is about 740 m downriver from the Susquehanna SES discharge diffuser. Both sites are about 40 m from the west bank. River temperature, level, and flow were monitored at the 1; oor ' tory (Table A-1). Temperature and depth of the river were recorded contitmcusly on seven-day graphs. Sensors for both recorders were located on the river bottom within 30 m of the bank. Temperature (C) was read directly from the graph, whereas depth (f t) was converted to river level (m) above mean sea level (ms1). River level data were used to calculate flow (m /s) past the laboratory. Daily means of the temperature and level recordings were determined by averaging hourly values from 0100 through 2400 h. Daily minimum and maximum values and their respective hours of occurrence were tabulated. When either a minimum or maximum value remained constant for several hours in a day , only the first hour of occurrence was noted. Physicochemical data were collected at the SSES and Bell Bend sites twice per week from April through September, and once per week from January through March and from October through December. All samples were collected between 1200 and 1400 h. A grab sample and dissolved oxygen sample of surface water were taken while drifting over each site E/OOM. 8 in a boat. Air and surface water temperatures, Secchi disc depth, and prevailing weather conditions were also determined at each site (Table A-1)."iver level and flow at colle efon time were also tabulated with the SSES data. Samples we're immediately transported to the laboratory and analyzed (Table A-1) for dissolved oxygen, pH, alkalinity, turbidity, sulfate, specific conductance, and residues (total, fixed total, nonfiltrable, and filtrable). Each laboratory analysis was performed at least twice and the mean was recorded. All calculations were maintained in bound notebooks. Aliquots of the grab sample were fixed for total and dissolved ir 1 analyses (Table A-1) which were determined by personnel at the Pennsylvania Power and Light (PP&L) Water Laboratory, Hazleton, Pennsylvania. All analyses were conducted within the holding time interval recommended by the U. S. Environmental Protection Agency (EPA 1974) . Diel physicochemical data were collected at SSES once per month from April through September during periods of stable river levels. Air and water temperature, dissolved oxygen, and pH were monitored at 3-hour intervals. Methods for collection and analysis were the same as previously described with the exception that replicate analyses were not performed for pH and dissolved oxygen. The 1978 physic chemical data collected at SSES were compared to those obtained in previous years. Nonparametric statistics were used to determine if:

1) year to year changes had occurred in each parameter, and 2) a trend among years was present.

Friedman's two-way analysis of <;-4,, n < ry m) e UYM

• 9 variance test (S) was used in the first determination and Page's distribution-free test (L) for ordered alternatives in the second (Hollander and Wolfe 1973). The tests were based on monthly cean values; only complete sampling years (1973-78) were used.

Personnel from the PP&L Water Laboratory collected physicochemical data from the river once each month at the Susquehanna SES Biological Labor.. tory (Fig. A-1). Water temperature and dissolved oxygen were measured in the field; all other determinations were made at the PP&L Laboratory according to S tandard Meth ~fs (APHA 1975) _r Methods for Chemical Analysis of Water and Wastes (EPA 1974) . RESULTS AND DISCUSSION Throughout 1978, the river cemperature ranged frcm -0.1 C, recorded on 8 days from 3 January through 15 March, to 30.0 C on 23 July (Table A-2).The minimum daily mean temperature G.0 C was recorded on 12 iays from 4 January through 5 February and the maximum daily mean temperature, 28.2 C, occurred on 23 July. The daily mean temperature varied least in February (Standard Error = 0.03), and most in May (SE = 0.67). The minimum monthly mean temperature, 0.2 C, occurred in January and February and the maximum, 24.8 C, in August. Daily water temperature ranges of 0.5 C or greater occurred in all months and in 98% of the days from April through September (Table A-2). Fluctuations of 3.0 C or greater occurred in July, August, and September. 370013. 10 The maximum daily fluctuation, 4.1 C, occurred on 23 August. The river level ranged from 148.21 m above .aean sea level (msl) on 16 and ' September to 152.97 m above msl on 28 January and 23 March (Table A-3) . The minim m daily mean riv .: level (148.23 m above msl) occurred ou 16 and 17 Nytember and the maximum (152.87 m above msl) on 23 March. The daily mean river level varied least in July (SE = 0.016) and most in March (SE = 0.276) . The lowest monthly mean level (148.39 m above msl) occurred in July and the highest (150.58 m above ms1) in April. River flow ranged from 28 m /s on 16 and 17 September to 3,172 m /s on 28 January and 23 March (calculated from minimum and maximum river levels). Daily mean flow was least (31 m /s) on 16 and 17 September and greatest (3,057 m /s) on 23 March (Table A-4). The daily mean flow varied least in July (SE = 3.1) and most in March (SE = 187.7). The monthly 3 mean flow was lowest in July (60 m /s) and highest in March (1,036 m /s). Physicochemical data from the SSES and Bell Bend sites (Tables A-5 through A-16) are summarized in Table A-17. Data collected upriver from the intake structure (SSES) and downriver from the discharge diffuser (Bell Bend) were similar throughout 1978. This is of particular interest because most of the river-related work sssociated with the construction of the Susquehanna SES intake structure and discharge diffuser was accomplished in 1978. Statistical analyses of physicochemical data collected at SSES from 1973 through 1978 showed improved water quality of the river similar to 370014 11 that observed from 1973 through 1976 (Jacobsen and Soya 1977) and from 1973 through 1977 (Soya and Jacobsen 1978). Using Friedman's test, significant differences were found among years for pH (S = 30.155, DF = 5, P<0.001), total alkalinity (S = 15.133, DF = 4, P<0.01), dissolved oxygen (S = 16.512, DF = 5, P<0.01), total iron (S = 19.381, DF = 5, P<0.01), dissolved iron (S = 22.976, DF = 5, P<0.001), and turbidity (S = 17.595, DF = 5, P <0.01) . Page's test showed a significant increasing trend among years for pH (L = 1,027, P<0.001), total alkalinity (L = 599, P<0.001), and dissolves oxygen (L = 962, P<0.01), and a significant decreasing trend for total iron (L = 991, P<0.001) and turbidity (L = 993, P<0.001) . A significant decrease was also found for sulfate (L = 936, P<0.05) even though no significance was found among years with Friedman's test. No decresse could be detected in the concentrations of dissolved iron. Several of these trends can be seen in plots of monthly mean values for selected parameters from 1972 through 1978 (Figs. A-2 and A-3) . River rater quality began to improve in 1972 with the termination of pumping mine water into the river at several locations upstream from the Susquehanna SES site (Jacobsen and Soya 1976). Mine pollution, however, has not ceased completely because some ef fluents continue to enter by gravity flow. In each of the three intervals that physicochemical data were tested for trends (1973-76, 1973-77, and 1973-78), four parameters have consistently shown significantly improved water quality. Dissolved oxygen and pH have increased whereas total iron and turbidity b' .e decreased. In addition, 370015 12 an increase in total alkalinity (sampling began in 1974) occurred in the 1974-77 and 1974-78 intervals. The trend was signiiicant in the first 'interval (P<0.05) and highly significant in the second (P<0.001) . Trends in other parameters, such as sulfate, specific conductance, and dissolved iron, have not always been so conclusively supportive of improved water quality. However, when changes in these trends are considered with regard to seasonal fluctuations in river flow and temperature, the overall results also reflect better water quality. Sulfate e:.nibited a significant decrease in the 1973-76 interval, no trend in 1973-77, and a second significant decrease in the 1973-78 interval.Variability in river flow during the las t year of each interval probably af fected the results, since sulfate concentrations are inversely related to flow (Figs. A-2 and A-3). From 1973 through 1978, the highest annual river flow occurred in 1976, followed by a lower than average flow in 1977 and the lowest flow in 1978 (Fig. A-2). In 1977 and 1978, sulfate ions should have been successively more concentrated. Therefore, even if the number of sulfate ions had decreased, it would not be evident because of an increase in sulfate concentrations due to decreased flow. This is probably what occurred in 1977 wh2n the trend was terminnted. in 1978, however, the trend reoccurred despite the low flow conditions. Significant decreases found in specific conductance during the 1973-76 and 1973-77 intervals were not detected in the 1973-78 interval. S7001G 13 Because specific conductance is also inversely related to river flow, discontinuance of the trend was probably caused by unseasonally low flows from September through December in 1978 (Fig. A-2). Specific conductance was unusually high during this period (Fig. A-2) as dissolved minerals remained concentrated in the river water. Consequently, the average specific conductance for 1978 (based on Friedman's ranked sums) was higher than in the previous three years, and the downward trend ended. A significant decrease in dissolved iron occurred during the 1973-77 interval. It was initiated by a relatively low concentration of dissc eed iron in 1977, a year when mean rive: cemperature was the highest recorded since constant monitoring began in 1974. Gale et al. (1976) demonstrated that dissolved iron concentrations n river water decrease as temperature increases. In 1978, the river temperature moderated, dissolved iron increased, and no trend was found for the 1973-78 interval.It is likely that the decrease in dissolved iron will reoccur in future years, particularly if amounts of total iron continue to decrease. Diel studies at SSES in April and May 1978, were characterized by relatively little change in temperature, dissolved oxygen, and pH (Table A-18).Air temperature fluctuated more on the sampling date in April than in May, but, diel changes in water tempera ture were only 0.5 C on both dates. Overall, dissolved oxygen en-centrations increased from 2400 h through 1200 h then necreased. The range, hcwever, was less than 0.5 mg/l in each study. The pH values were nearly constant on both sampling dates. S70017 14 Diel fltctuations in temperature, dissolved oxygen, and pH were most pronounced during studies in June. July, and August (Table A-18). Minimum values for these parameters occurred between 2400 h and 0900 h and maximum values were recorded from 1500 h through 2100 h. The largest change in pH occurred in the June study when it increased from 7.4 at 0900 h to 8.1 at 1500 h. Maximum fluctuations in water temperature and dissolved oxygen were found in August. Water temperature rose from 23.0 C at 0600 h to 26.0 C at 1800 h and dissolved oxygen increased from 7.40 mg/l at 0600 h to 10.60 mg/l at 1500 h. In the September diel study, fluctuations in most parameters moderated in comparison to data collected during the three previous studies (Table A-18).Water temperature fluctuated only 1.5 C despite a 12.0 C increase in air t;mperature. Dissolved oxygen changed less than 2 mg/l as it increased from 8.30 at 0600 h to 10.10 mg/l at 1800 h. The pH ranged from 7.5 to 7.7. A total of 50 water quality parameters was analyzed each month from samples collected at the Susquehanna SES Biological Laboratory by personnel from the PP&L Water Laboratory (Table A-19). The relatively high concen-trations of iron, sulfate, aluminum, manganese, and magnesium in the samples indicates that coal mine pollution persisted at the site. Total iron concentrations in 7 of the 12 samples exceeded the 1.5 mg/l limit established for the river by the Pennsylvania Department of Environmental Resources (DER 1971) . Total maganese concentrations, however, did not surpass the DER limit of 1.0 mg/l in any month. S70018 15 Major cation and anion composition was similar to that found in 1977 (Soya and Jacobsen 1978). Calcium (i = 1.53 me/l) was the dominant cation in all sr,mples. The dominant anion in each sample was either bicarbonate (i = 1.J7 me/1) or sulfate (i = 1.11 me/1).

Diatoms composed 84.5% of the periphyton collected on cumulative and bimonthly plates in 1978. Green algae were second in abundance (14.2%) . Standing crops of periphyton were usually higher at Bell Bend than at SSES. Standing crops of periphyton peaked in October at Bell Bend (5,400 units /mm on the bimonthly plate) and in December at SSES (4,500 units /mm on the cumulative plate). Colonization rates of periphyton on bimonthly plates averaged only 62 and 96 units /mm per sampling period in February and December, respectively. Standing crops of phytoplankton peaked at both stations in June when there was an average of 27,400 units /ml. Diatoms composed 66.3% of the phytoplankton collected. Green algaa was second in abundance (32.8%). INTRODUCTION Algal density in periphyton samples from Susquehanna River stones varied widely in 1973 (Ichthyological Associates 1974) and subsequently, artificial substrates were used to reduce sample variability. Artificial substrates provided a more homogeneous surface for algae to colonize than did river stones. Of five substrates tested in 1974, frosted (sandblasted) acrylic was the most desirable (Gale and Gurzynski 1976) . 3"/0050 47 The primary objective in the 1977-78 study was to describe seasonal changes in the periphyton community colonizing frosted acrylic plates at two stations near the Susquehanna SES (Fig. A-1). One station (SSES) was 463 m upriver from the Susquehanna SES intake structure, 135 m from the west bank; the other (Bell Bend) was 397 m downriver from the discharge diffuser, 30 m from the west bank. PROCEDURES Brass pins fastened acrylic plates (22 x 30 cm) to an acrylic holder (Fig. B-1) on the river bottom. Projections that would catch drif ting detritus were eliminated from the holder. Plates iaced upstream at 5 from horizontal and offered little resistance to the current. The holders were placed near the channel where minimum and maximum water depths ranged from about 2.5 to 6.0 m, respectively. The concrete-filled holder was too bulky for a scuba diver to manipulate in strong currents ad was lowered to the river bottom on a submersible raft (Cale and Th< ion 1974). Steel stakes driven into the substrate held the holder in place. The upriver edge of the holder and the stakes were covered with small stones to prevent fouling by detritus. Eight plates were placed in the holders at each station on 16 December 1976. Three plates were randomly selected for sampling at two-month intervals at each station from February 1977 through December 1978 (Gurzynski and Gale 1978). One of the three plates was a spare that could be sampled if a plate was lost. Three replicate samples were taken from each plate. Slots where 970051 48 plates were removed were filled with clean plates that would be sampled the following period. The remaining five plates provided cumulative samples of 2 to 12 months duration in 1977. In 1978, the cumulative plates were submerged for 10-month intervals. Plates removed for cumulative sar ples were replaced by clean ones to maintain a constant current pattern. A scuba diver collected samples from the plates with a bar-clamp sampler (Cale 1975) . The sampler included a collecting cup which delimited a circular sampling area (415 mm ) and prevented loss of cells while the plate was retrieved from the river and while it was processed in the laboratory. Samples were cleaned by vibration (Cale 1975) with an ultrasonic dental cleaning probe that loosened almost all cells within a few minutes vibration. Dislodged cells were flushed into a collecting jar with water sprayed inside the collecting cup through the cleaning probe. Vibration lasted 10 minutes to reduce the chances of missing any cells. After vibration, the surface of the plate ' lad a " fresh" appearance where the sample was taken. Vibration may have damaged some cells, but tests in which samples were cleaned by:

1) saaping and brushing, and 2) scraping and vibration, more cells per unit area were obtained by the second method.(Gale 1975). Samples were then preserved with formalin and, af ter settling 10 days, were concentrated to 50 ml by siphoning. One half of the concentrate was sent to Dr. Rex L. Lowe, Department of Biology, Bowling Green State University, Bowling Green, Ohio, for identification and enumeration. The remainder was placed in our reference collection for a 12-month period.

37005?, 49 A 1-liter phytoplankton sample was collected near the river surface at each periphyton sampling station on the same day periphyton samples were collected. The samples were concentrated in the same manner in which the periphyton samples were, except that they were siphoned three times becerse of their greater initial volume. Algal cells in periphyton and phytoplankton samples that contained chloroplasts were enumerated in terms of units (Gale and Lowe 1971). In most inst:inces, at least 1,500 units were enumerated and identified in each sample (about 500/each of 3 subsamples) . Extremely low algal densities in some subsamples made it impractical to count 500 units. Counts were made using a Palmer co;ating cell at 430 X magnificction. Higher magnification, ine,luding electron microscopy, was used for some identifications. Periphyton was identified to genus and the more abundant forms to species using keys by Hustedt (1930) and Prescott (1962). RESULTS AND DISCUSSION Periphyton In 1978, a total of 51 genera of algae was collected in~36 samples from acrylic plates above the intake; 59 genera were collected in samples taken below the discharge. A summary of these data appear in Tables B-1 through B-4; raw data are in Tables B-5 through B-28. Thirty species of algae were identified that composed 5% or more of the total units counted in samples from the two sampling stations (Table B-29).Diatoms occurred in about the same proportions at Bell Bend (84.6% S700a3 50 of the total) and at SSES (84.3% of the total) . Overall, diatoms composed 84.5% of the total periphyton at both stations combined. Five species of diatoms that composed over 5% of the total units counted at SSES composed less than 5% of the total at Bell Bend (Table B-29); the reverse was true for three species at Bell Bend. Blue green algae were relatively scarce at both stations, but in December composed over 5% of the total units counted at Bell Bend. One species of blue green, Schicothrix calcicola, was ide::tified at Bell Bend. Most of the algae found were " clean water" forms and only 3 of the abundant species in our samples were among the top 10 species of those tolerating much organic pollution listed by Palmer (1969). These were Nitzschia palea, Scenedesmus quadricauda, and Ankistrodesmus falcatus. Only 3 of 24 species of abundant diatoms (Table B-29) were rated as"acidophilous" by Lowe (1974) . Some of the others were rated " indifferent" but most were "alkaliphilous." It is obvious from Fig. B-2 that algal colonization of clean substrates (bimonthly plates) at both stations was extremely slow in winter 1978, as it was in 1977, and averaged only 62 and 96 units /mm per sampling period in February and December, respectively. Diatoms rapidly colonized substrates between April and June as the river warmed. The colonization rate remained high from June through October, 1978. In 1977, colonization had slowed by the October sampling date. The high colonization rate in October 1978 may have re ulted from the low river levels (Fig. B-3) . Currents associated with high river levels scour much of the periphyton from the substrate (Gale et al. 1976). S70054 51 In 1978, as in 1977, algal density at Bell Bend was usually higher 2 than at SSES. In 1978, there was an average of 350 algal units /mm on bimonthly acrylic plates and 1,240 units /tn on cumulative acrylic plates at SSES. Densities at Bell Bend were somewhat higher with an average of 1,450 alga 1 units /mm on bimonthly plates and 1,230 units /mm on cumulative plates.In 1978, the overall standing crop of algae at both stations were higher than those encountered at the same sites in 1977. There was a major difference in when peak densities occurred (Fig. B-2). In 1977, very high algal densities occurred in June and August samples, whereas in 1978, the standing crop did not peak until October at Bell Bend (5,400 units /mm on the bimonthly plate) and December at SSES (4,500 units /mm on the cumulative plate). The high standing crop on cumulative plates in December was unusual and probebly occurred because of the unusually low river flow in autumn (Fig. B-3) . High river flows usually occur sometime in October or November (Fig. A-2) and scour most of the algae from the substrate before the December sampling date. Phytoplankton Phytoplankton in samples collected at SSES was nearly identical to that in samples taken at Bell Bend (Fig. B-4) . There was a total of 49 genera of algae in 6 samples at SSES and 48 genera in 6 samples from Bell Bend (Tables B-30 and B-31) . 370055 52 Nineteen species of algae were identified that composed 5% or more of the total units counted in samples from the two sampling stations (Table B-32) . Overall, diatoms were the most abundant type c' algae at bori stations and composed 66.3% of the total algal units counted. Two species of diatoms (Chelotella scclligera and Cymbella minuta) that composed over 5% of the total units at SSES composed less than 5% of the total at Bell Bend (Table B-32); the reverse was true for two species (!!alcaire distans and Navicula cryptocephala var. veneta) at Bell Bend. In June and August, green algae was abundant at both sites (Fig. B-4) and composed 43.2% of the total standing crop. Similar trends were obse rved ir summer, 19 72-73 (Ichthyologit.a1 Associates 19 74) . Overall, green algae composed 32.8% of the total cigal units counted in 1978. Most of the algae found were " clean water" forms and only 2 of the abundant species were listed by Palmer (1969) in tae top 10 species of those tolerating much organic pollution. These were Hitaschia palca and Scencdescus quadricaula. Only one of the species of abundant diatoms were rated as "acidophilous" by Lowe (1974). Some were rated "indif ferent" but most were "alkaliphilous." Standing crops of phytoplankton were low in February and April but increased by about 26-fold to the season's high in June when there was an average of 27,400 phytoplankton units /ml at the two sites. The standing crop at SSES in June was 28,400 units /ml; at Bell Bend it was 26,500 units /ml. Such small differences probably reflect normal sampling variability. The standing crop at both stations remained fairly high throughout the summer and did not decline sharply until December. WOO 5G 53 REFERENCES CITED Gale, W.

Two sites were upriver from the intake structure (SSES I and II) and two were below the discharge diffuser (Bell Bend I and III). Overall mean density of macroinvertebrates at SSES was 19,200 organisms /m and at Bell Bend it was 8,600 org/m . Oligochaetes (Naididae and Tubificidae), mayflies (Caenidae and Heptageniidae), caddisflies (Hydropsychidae), and dipterans sChironomidae) 'composed more than 90% of the total macroinvertebrates at each site. In 1978, total mean density and biomass were 3-fold and nearly 2-fold greater than in 1977, respectively; increases were primarily due to the much greater standing crop present at both stations in October 1978. INTRODUCTION Because benthic macroinvertebrates are relatively sessile and occur in laige numbers, they are useful organisms to monitor water quality. Some species are highly selective in their choice of habitat and are, therefore, important indicators of both environmental quality and change (Paine and Gaufin 1956). General environmental evaluations can be made when macroinvertebrates are identified to order or family (Mackenthum and Ingram 1967), but species within these groups have wide ranges of physicochemical tolerances (Resh and Unzicker 1975). For the latter reason, it is desirable to identify organisms to species for ir.terpretation of macroinvertebrate data. The$5005)$ 89 problem of insufficient taxonomic keys (especially for immature insect stages) has been ameliorated by recent literature (Lewis 1974; McCafferty 1974; Beck 1976; Edmunds et al.1976; Resh 1976; Saether 1976, 1977a, b; Surdick anc Kim 1976; Wiggins 1977; and Merritt and Cummins 1978). The objective of this study .was to monitor seasonal changes in the benthic community of the Susquehanna River near the Susquehanna SES throughout 1978. PROCEDURES Benthic macroinvertebrates were collected at four sites (two stations) near the Susquehanna SES (Fig. A-1) . Two sites (SSES I and II) were upriver from the intake structure, and the other two (Bell Bend I and III) were downriver from the discharge diffuser; the Bell Bend III site was added in 1978. Locations of the other sites were unchanged from 1977 (Table C-1). Three replicate dome suction samples (Gale and Thompson 19 75) were collected at each site on 17,18 April; 13-16 June; and 10, 12 October 1978. Af ter the dome sampler was lowered from a boat to the river bottom, a scuba diver moved it upriver or laterally to the first undisturbed area encountered where an adequate seal between the sampler band and the substrate could be established. The area (0.163 m ) enclosed by the sampler was vacuumed for five minutes with a hose leading to a bilge pump mounted on the sampler. Sand, gravel, and organisms were pumped into a nylon net (216-p mesh); larger stones were carefully vacuumed and discarded. g/0093 90 When all three replicates were collected, they were returned to the boat by the diver. One of three replicate samples was used for biomass estimates. It was important to keep organisms alive since Howmiller (1972) found that a considerable weight loss occurred due to the effects of preservatives. Therefore, organisms were sorted and identified as quickly as possible af ter collection (decomposition occurred quickly af ter death), and they were usually identified to family. Mollusc shells were dissolved in 1% HCL (decalcification) . ' Organisms were then counted, placed in aluminum foil containers, and dried in a Precision Scientific Thelco Model 17 oven at 100 C for at least 12 hours. Af ter drying, they were cooled to room temperature in a glass dessicator and weighed using a Mettler H10W balance.The other two replicates were washed, sieved (U.S. Standard No. 60 sieve), and preserved in 10% buffered formalin. After a sample was macroscopically sorted, 1/4 of the residue was randomly selected in an acrylic subsampler (Ichthyological Associates 1973) . Subsamples were examined with a dissecting microscope (30 X) and macroinvertebrates removed. The number of organisms in each su'osample was multiplied by 4 and added to the number found in the initial sorting. Total number of organisms per sample was multiplied by 6.135 to convert the data to numbe rs /m . Invertebrates were identified (usually to genus or species) with the keys of Pennak (1953), Allen and Edmunds (1962, 1963a, b, 1965), Parrish (1968), and others noted above. wig 034 91 Data were analyzed using a series of BASIC computer programs written for a Hewlett-Packard 9830-A c sputer. These programs first calculated a between-sample similarity matrix using the Bray-Curtis (1957) index: nlX1-X2lE 3 3 , 1 - p=1 n (X1 +X2 )E 3 3 , J=1 where X1j and 22j represent the abundance of taxon j for samples 1 and 2, respectively, and n represents the number of taxa captured. The similarity matrix was then clustered by the group-average sorting technique (Clifford and Stephenson 1975) . In this way samples could be classified according to similarity in taxonomic composition and abundance. RESULTS AND DISCUSSION Standing Crop Overall mean density of macroinvertebrates in 1978 was much higher at SSES (19,200 organisms /m ) than at Bell Bend (8,600 org/m ) (Table C-2). 011gochaetes (Naididae and Tubificidae), mayflies (Caenidae and Heptageniidae), caddisflies (Hydropsychidae) and dipterans (Chironomidae) composed more than 90% of the total number of macroinvertebrates at each site. Three genera of chironomids (Rheotanytarsus sp. , Polypediltcn spp. , and Conchapelopia spp.) were especially numerous and composed 28.1% of the standing crop. On the average, there were 3-fold more macroinvertebrates collected in 1978 than in 1977. F/OO3G 92 The lowest standing crop of macroinvertebrates was found in April (Fig. C-1) at all sites (Tables C-3 through C-6) . Overall mean density was 1,000 org/m . Nematodes (28.1% of the standing crop) were abundant in April; at Bell Bend III there were 900 individuals /m . 011gochaetes (21.0%), chironomids (15.5%), and hydropsychids (13.6%) also predominated at both stations. By June, the standing crop of macroinvertebrates had increased markedly at all sites with the largest gains being made at SSES I and II (Tables C-7 through C-10). Much of the increase at all sites was due to the oligochaete population which composed 45.9% of the total standing crop. At SSES II there were 8,800 naidids/m . Also, the density of mayflies (Caenidae and Heptageniidae), caddisflies (Hydropsychidae), and dipterans (Chironomidae) increased ; each of these groups composed about 17% of the standing crop. Ntm' ers of macroinvertebrates peaked at all sites in October (Tables C-Il through C-14; Fig. C-1) . Density at SSES I (i = 53,000 org/m ) was much higher than had been found at any time in the previous three sampling years at either station. The greater densities were probably due to low river flow in September and the first half of October 1978 (Fig. A-2) . High river flows in late September 1975 (Hurricane Eloise) and in October 1977, seemed to have reduced macroinvertebrate standing crops (Deutsch 1976, 1978). In October, chironomids (i = 12,100 org/m ) and caddisflies (i = 9,600 org/m ) composed 77.5% of the standing crop. Three genera of <g100'dG. 93 chironomids (Rheotanytarsus sp., Conchapelopia spp. , and Polypadilum spp.) and two genera of hydropsychid caddisflies (Chewnatopsyche spp. and Hydropsyche spp.) were especially numerous. At 3 ell Bend I, leptocerid and psychomyiid caddisflies composed over 10% of the standing crop.Cluster analysis showed marked seasonal differences in taxonomic compos!. tion and abundance at all sites (Fig. C-2) . Analysis of four years of data (1975-78) revealed that all months but one (April 1977) formed distinct clusters. As a whole, the analysis gave strong evidence that seasonal changes were more important in characterizing the macro-benthic community than station or site dif ferences. Individual sites, often difficult to categorize without multivariate techniques, generally represented distinct entities. The e-ly misclassi-fications (fusion of two samples from different sites) oc urred in early spring (1975-78) when high water may have disrupted the distribution of macroinvertebrates. Between-site similarity patterns were inconsistent. For example, the SSES sites exhibited no more affinity to each other than to either of the Bell Bend sites (Fig. C-2) . Based on these analyses, SSES is similar enough to Bell Bend to serve as a control. A list of species found in dome samples from 1975 through 1978 is presented in Table C-15. Members of the Interpunctatum group in the genus Stenonema (Ephemeroptera: Heptageniidae) were placed in the genus Stenacron as recommended by Lewis (1974) . In 1978, there were six additions S70037 94 to the more comprehensive species list of 1977 (Deutsch 1978) . These identifications are in the process of being verified. Included were the mayf1ies, Ephems vila sordida, Heterocloeon sp., and Stenacron gildersleevei; the caddisflies, Ceraclea neffi and Ptilostomis sp.; and an aquatic noctuid (Lepidoptera) larva. Biomass Biomass (dry weight) in 1978 (11.0 kg/ha) was 79.0% greater than it was in 1977 (6.2 kg/ha) . Total mean biomass was greater at SSES (16.7 kg/ha) than at Bell Bend (5.4 kg/ha) in 1978 (Tables C-16 and C-17) . Hydropsychid caddisflies composed most of the biomass at SSES (63.7%) and Bell Bend (29.3%). Other major groups at Bell Bend were heptageniids (16.5%), oligochaetes (9.8%), and potamanthids (9.2%) . Biomass was lowest in April and highest in October. In April, 58.0% of the biomass at the four sites was composed of hydropsychids (i = 1.1 kg/ha) . In June, oligochaetes (i = 0.9 kg/ha) and mayflies (i = '.?kg/ha) composed 60.8% of the biomass. In October, hydropsychids (i = 16.9 kg/ha) composed 69.2% of the biomass. REFERENCES CITED Allen, R.

A total of 1,636 larvae (about 90% prolarvae) of at least 14 species was collected from 4 May through 17 August. Over 90% of the total number captured at both sites was composed of quillback, minnow spp., tesse11ated darter, and carp. Maximum densities at SSES and Bell Bend occurred on 31 May when 26.2 and 29.5 fish /10 m were collected, respectively. No significant dif ferences were observed between the combined catches at both sites. Significantly more larvae (P<0.001) were taken at night than during the day, and more were captured near the surface than near the bottom. INTRODUCTION Seasonal fluctuations in the relative abundance and density of drifting larval fish near the Susquehanna SES intake structure has been monitored since 1974 (Buynak and Mohr 1976, 1977, 1978a; Gale and Mohr 1978).In 1978, monitoring was conducted upriver from the intake and downriver from the station's discharge diffuser. Simultaneous monitoring was conducted at these sites to establish a baseline of preoperational conditions. PROCEDURES Larval fish were sampled at SSES and Bell Bend pumping sites (Fig. D-1).The site at SSES was located 190 m upriver from the Susquehanna SES intake s tructure. The Bell Bend site was 920 m downriver from the 370.l_[t# 124 discharge dif fuser. Both sites were within 50 m of the west bank. Depth was 3.3 m at SSES and 2.3 m at Bell Bend when the surface elevation of the river at the Susquehanna SES Biological Laboratory was 148.6 m above mean sea level. Samples were collected simultaneously at both sites with similarly equipped pontoon boats on 4, 9, 23, and 31 May; 7, 14, 21, and 28 June; 5 and 20 July; and 2 and 17 August. At each site, river water was pumped through a 216-p mesh net with a high-capacity, gasoline-powered trash pump (Gale and Mohr 1978) . Three replicate surface and bottom samples (5 min each) were taken at 0900 and 2100 h. Surface replicates were taken before bottom replicates. The volume sampled in each replicate was determined by multiplying pumping duration (5 min) by pumping rate. The pumping rate was checked on each sampling date with a hand-held tachometer (Stewart-Warner, Model 757-W).The pumping rate of each pump was tested monthly by timing the filling of a 1,2Fs-liter trough. Tachometer readings taken during these tests were compm ed with those taken on each sampling date to assure that each pump was functioning at near maximum capacity. The volume of each replicate ranged from 11.3 to 12.8 m in Fby. Af ter adjusting the pump engines, constant volumes of 12.0 m per replicate were obtained from June through August. Each sample was preserved in the field with 10% formalin containing rose bengal stai.., and transported to the laboratory where larvae were sorted. Af ter sorting, identifications and life stages (prolarva or postlarva) of all larvae were determined using a dissecting microscope O!.,\ eS 125 (10-70 X). Prolarvae were defined as fish with yolk and postlarvae were those without yolk (Hubbs 1943). Once scalation began, fish were considered juveniles and not reported. Where necessary, identifications were made by comparing larvae to our reference series of 31 spc;ies of laboratory-reared specimens and with developmental information given in Buynak and Mohr (1978b-d; 1979a-d). We also used keys and descriptions in Fish (1932), Norden (1961), Mansueti (1964), Mansueti and Hardy (1967), May and Gasaway (1967), Siefert (1969), Taber (1969), Meyer (1970), Gerlach (1973), Lippson and Moran (1974), Hogue et al. (1976), Snyder et al. (197 /) , and Taubert (1977). In a few instances, positive identification to species could not be made, either because of damaged specimens or a lack of adequate keys. These fish were identified to the lowes t taxon possible. Severely damaged fish which could not be identified were tabu!ated as fragments. Names and order of listing (Table D- 1) conform to Bailey et al. (1970). All specimens were stored in 10% buf fered formalin. Data were processed with a Hewlett-Fnekard 9830-A computer and stored on permanent magnetic disc files. An impact printer was used to print out raw data and density tables. Densities were analyzed using a 4-vay analysis of variance (Hewle t t-Packard 1974). Data from the fi rs t two sampling dates were excluded because only one larva was captured. The factors tested were stations, dates, day-night, surface-bottom, and their first order interactions. Results of the second and third order interactions were ambiguous and 3701%9. 126 are not presented. Because replicate means were positively correlated with their variances, data were given a log (x+1) transformation prior to analyses. Upon completion of the analysis of variance, Bartlett's test for homogeneity of variance was applied. The nonsignificant res its in Bartlett's test indicated that variances were suitably homogeneous for significance testing. The 5% probability level was used to determine significance in each test. RESULTS AND DISCUSSION A total of 1,636 larvae of at least 14 species was collected from 4 May through 17 August at the SSES and Bell Bend sampling sites (Tables D-1 through D-13) . At SSES, 851 larvae were captured, and at Bell Bend 785 were taken. About 90% of the larvae collected at both sites were p rola rvae . Fishes in three of five families composed about 98% of the total number of larvae captured at both sites (Tables D-14 and D-15). Suckers were the most abundant (SSES, 58.0% and Bell Bend, 56.5%) followed by minnows and carp (SSES, 27.2% and Bell Bend, 22.5%) and perches (SSES, 12.3% and Bell Bend, 18.7%). Fishes in these three f amilies have composed similar percentages of the total catch at SSES each year since 1974 (Buynak and Mohr 1976, 1977, 1978a; Cale and Mohr 1978) . Over 90% of t'ie total number at each site was composed of quillback, minnow spp., tesr.ellated darter, and cr.rp (Tables D-14 and D-15). Quillback was the most s'sundant; it composed about 54% of the total catch at each site. 370.L30 127 At SSES, minnow spp. were second in abundance (17.2%) followed by tessellated darter (11.5%) and carp (9.1%). At Bell Bend, tessellated darter was second in abundance (17.0%) followed by minnow spp. (13.3%) , and carp (8.7%) . On 23 May, prolarval quillback, white sucker, tessellated darter, walleye, and perch spp. were captured at SSES, and the same fishes were taken at Bell Bend, except for tessellated darter (Tables D-14 and D-15). By 31 May, carp, minnow spp. , shorthead redhorse, crappie spp., and tessellated darter were taken at both sites. One or more of the three sucker species (quillback, white sucker, and shorthead redhorse) were found at both sites from 23 May to 28 June. Although walleye was not taken af ter 31 May, other perches, mostly tessellated darter, were captured at each site through 20 July. At both sites, carp was taken through 28 June and minnow spp. were found through 17 August. Sunfishes (rock bass, bluegill, sunfish spp. , and crappie spp.) and catfishes (white catfish, channel catfish, and margined madtom) composed only about 2% of the total number of larvae at both sites (Tables D-14 and D- 15) . Some of these fishes, which exhibit parental care (Scott and Crossman 1973), may not have been drif ting when they were drawn into the intake.Sunfishes were found at either SSES or Bell Bend from 31 May to 20 July, excluding 5 July. Catfishes were taken at either SSES or Bell Bend on 28 June, 5 and 20 July, and 2 August. Fishes in these families have always composed a small percentage of the total catch at SSES since 1974 (Buynak and Mohr 1976, 1977, 1978a; Gale and Mohr 1978) . bh. ?.U. 128 Fluctuations in larval fish densities were similar at SSES and Bell Bend throughout the 1978 sampling season (Tables D-14 and D-15; Fig. D-2) . At both sites, the greatest increase in density occurred from 23 to 31 May. At SSES, the density increased from 4.7 to a maximum of 26.2 fish /10 m , and at Bell Bend, it increased from 1.9 to a maximum of 29.5 fish /10 m . One week later, densities at both sites decreased to less than 10.0 fish /10 m . By 28 June, an overall mean of 2.7 fish /10 m was found at the two sites, and on most sampling dates from 5 July to 17 August, less than 1.0 fish /10 m was taken. Highly significant differences (P<0.001) were found inthe densities of drifting larvae relative to sampling dates at SSES and Bell Bend (Table D-16).Such differences were expected because of fluctuations in the density of larval fish throughout the sampling season (Fig. D-2) . There were no significant differences between the combined catches of larval fish at SSES and Bell Bend (Table D-16) . Except for quillback, the catches of each species were not significantly dif ferent. Quillback densities were significantly greater (P<0.001) at SSES. Closer examination of data revealed that this difference was confined to higher densities at SSES on the bottom (Tab 'es D-16 through D-24) . Although statistically significant, the biological importance of this occurrence is not known. Significantly more larvae (P<0.001) were taken at night than during the day at SSES and Bell Bend (Table D-16). This was also true in 1977 when similar results were obtained at SSES (Buynak and Mohr 1978a) . In 1978 at SSES, mean density at night (7.0 fish /10 m ) was over 2-fold greater than i 370132 129 during the day (2.9 fish /10 m ) (Tables D-17 through D-20). At Bell Bend, mean density at night (6.9 fish /10 m ) was nearly 3-fold greate.r tnan during the day (2.4 fish /10 m ) (Tables D-21 through D-24) . At both sites, significantly more (P<0.001) quillbach , white sucker, shorthead redhorse, and tessellated datter were captured at night. Significant day-night differences were not obtained for minnow spp. and carp. At SSES and Bell ",end, significantly more larvae (P<0.01) were taken near the surface of the river than near the bottcm (Table D-16) . This also occurred at SSES in 19T/ (Buynak and Mohr 1978a) . In 1978, the meau density at SSES was about 2-fold greater near the surface (6.2 fish /10 m ) compared with the bottom (3.7 fish /10 m ) (Tables D-17 through D-20) . At Bell Bend, it was nearly 3-fold greater near the surface (6.8 fish /10 m ) as compared to the bottom (2.4 fish /10 m ) (Tables D-21 through D-24). Significantly more (P<0.001) carp, minnow spp., and quillback were captured near the surface at both sites. No surface-bottom differences were found for tessellated darter, white sucker, and shorthead redhorse. The collection of so few white sucker (26) and shorthead redhorse (27), made dif ferences, if present, difficult to detect. In 1975 at SSES, when more larvae of both species were captured, distinct changes in their diel surface-bottom distributions were clearly demonstrated (Gale and Mohr 1978) . As stated previously, the densities of minnow spp. did not exhibit significant day-night differences at SSES and Bell Bend, but they did show significant surface-bottom differences. Although densities of minnow spp. were greater on the bottom in both day and night samples, the day-night vs. surface-bottom interaction effect showed that a significantly WlO.$ $e3 130 higher proportion of the larvae were captured near the surface at night. These day-night differences were expected because they did occur when diel studies were conducted at SSES in 1974-76 (Buynak and Mchr 1978a, Gale and Mohr 1978) . However, since samples were collected less frequently while monitoring in 1978, day-night dif ferences were not detectable. Furthermore, dif ferences in the drif ting behavior of individual minnow species could have confounded the analysis. Surface-bottom differences could not be detected in densities of tessellated darter, but a significant interaction between day-night and surface-bottom suggested a diel drif t pattern. Larvae were never captured near the surface in day samples and their mean densities were relatively low near the bottom. However, in night samples, mean bottom densities increased nearly 5-fold to about 1.0 fish /10 m , while near the surface they increased from 0.0 to 1.3 fish /10 m (Tables D-17 through D-24). Diel studies at SSES in 1974-76 (Buynak and Mohr 1978a, Gale and Mohr 1978) showed a distinct pattern of diel drif t for tessellated darter. Significant day-night dif ferences could not be found for carp, even though their densitics were greater at the surface. In addition, the non-significance of the day-night vs. surface-bottom interaction indicated that a diel drif t pattern had not occurred. These results were in agreement with some of the previous diel studies. Buynak and Mohr (1978a) showed that the vertical distribution of carp at SSES was similar at the surface and botton in 1976 when abundance was low. However, they conducted another diel study in the same year when carp were more abundant and documented significantly higher densities at night near the surface. ty/G.L34 131 REFERENCES CITED Bailey, R.

A total of 4,639 specimens of at least 24 fishes was observed while electroffshing and 1,977 specimens of 21 fishes was captured by seine. Walleye, white sucker, smallmouth bass, shorthead redhorse, quillback, and northern hog sucker composed 75% of the total observed while electrofishing. Nearly 90% of the seine catch at both stations was composed of spotfin shiner, spottail shiner, bluntnose minnow, comely shiner, and white sucker. 0;currence of the more abundant fishes was similar at both stations. No significant differences were found in either the total number of fishes or their species composition at the electrofisher and seine sites. No significant differences were found in the total number of specimens at either station or at the east and west bank sites within each station. Significantly more fish were observed while electrofishing at night than during the day at both stations.A relatively large year class of walleye was produced in 1978. INTRODUCTION Seasonal fluctuations in species composition and relative abundance of fishes near the Susquehanna SES has been monitored since 1971 (Ichthyological Associates 1972, 1973, 1974; Buynak and Gurzynski 1976a, b, 1977a-d,1978; and Buynak et al.1978a, b). Beginning in 1976, emphasis was placed on a comparison of fisheries data collected at two sampling stations, one was located upriver from the intake of the Susquehanna SES 8701bb 162 and the other downriver from the discharge diffuser. Throughout 1978, comparative sampling at both stations was conducted to establish a baseline of preoperational conditions. PROCEDURES Fish populations were sampled by electrofisher and seine, upriver from the Susquehanna SES intake (SSES) and downriver from the discharge diffuser (Bell Bend). Stations were electrofished with a pulsed direct-current electrofisher similar to that described by Novotny and Priegel (1974).It consisted of a 4-kw generator and a variable voltage pulsator mounted in a 6-m flat-bottomed boat powered by an outboard motor. Seine samples were collected with a 7.6-m bag seine with 0.64-cm mesh. Electrofishing was conducted at two 1,000-m sites, one near each river bank, at SSES and Bell Bend (Table E-1; Fig. D-1). The sites were shocked monthly from March through December during ice-free periods when river level at the Susquehanna SES Biological Laboratory was between 148.5 and 150.3 m above mean sea level (msl). All sites were sampled once during the day and once at night by slowly driving the electrofisher downriver parallel to the current f rom 1 to 50 m from the river bank. Each 1,000-m run was considered one unit of effort. Day sampling began about 3 hours after sunrise and night sampling bagan about I hour after sunset. All species of stunned fish larger than about 10 cm (excluding cyprinids, except carp, river chub, and fallfish) were identified and counted by two observers on the bow of the boat. Fish that surfaced behind the observers SVOi66-163: s' , I were identified and enumerated by the boat operator. Data were recorded 'on a cassette tape recorder (Craig No. 8108). Fish which could not be _positively identified in the water were captured, identified, and released; those that escaped were recorded as unidentified. , Seine samples were collected at two sites, one on each bank, c:. SSIS and Bell Bend (Table E-1; Fig. D-1). Sites were selected in areas free of underwater obstructions to increase sampling ef ficiency. Samples were , collected monthly from April through Oc > ober during ice-free perf ocis when river level at the laboratory was less than 149.4 m above nsl. Seining was conducted at night beginning about I hour after surset. Two replicate . i hauls were made at each site. During the first haul, one ceine 1. rail was held on the river bank and the other was taken into the river to a depth of about 1.3 m or a distance of about 6 m. The brail on the river bank was held stationary while the other was pulled slowly upriver and then L to shore.Fish were removed from the not and preserved with 10% formalin. 'The seine was then returned to the initial starting point' and a ;ecend haul taken. The two hauls were combined and considered one unit of effort. , In the la oratory, all specimens were identified, separated by species, and stored in 407 isopro,yl alcohol. Identifications were based on characteristics given in keys by Pflieger (1968), Eddy (1969), and Scott and Crossman (1973). , Air and surface water temperatures and a surface grab sample of , water were obtained at the downriver end of each electrofishing run and '.at each seining site during the collection of fish samples. Each sample _S /O.ti;7--O 164.was ' nalyzed in the laboratory for dissolved oxygen, pH, turbidity, and i specific conductance (ulect?" fishing only) according to methods in Table A-1.Both the fisheries and physicochemical data were processed with a _llewlett Fackard 9830-A computer and stored on permanent magnetic disc files. A thermal nrintout of these data was checked for accuracy before final data tablet, were printed with an impact printer. Names of fishes and the order of listing conform to Bailey et al. (1970) . The data were analyzed with three statistical tests. A nonparametric sign test (Siegel 1956) was used to determine if there were any dif ferences a in the number 6f fish captured between stations and at sites within statiors. Day-night differences were alro tested for electrofishing data. Two significance tests (liendrickson 1978) were used to determine if patterns -of species occurrence were present in tl:e data. The first, the mathematical , eqaivalent of' Cochran's Q-s tat!,stic, tested whether sites dif fered in the ,...numoer of species present. Because si tes .might have similar numbers of species, but dif ferent specien composition, a second test called an M-tne number of species in common at each statiatic, was used to compute- ~-1. ~ . -, BoththeQandMstatisticshaveanapproximately{hi-squared 'site.distribution. The 5% probability level v.hs used to determine significance i for all tests. \',\.\r 370.168,*o f./.s%f' ' %3 165 RESULTS AND DISCUSSION Electrofishing A total of 4,639 specimens of at least 24 fishes was observed using the electroffsher at SSES and Bell Bend (Tables E-2 through E- 12) .Of the 23 fishes recorded at SSES (Table E-13), six composed 75.9% of the total. Walleye was the most abundant (18.7%) fellowed by white sucker (17.9%), smallmouth bass (12.0%), shorthead redhorse (11.9%) . quillback (7.8%), and northern hog sucker (7.5%) . At Bell Bend, 21 ' shes were observed (Table E-14), six of these composed 74.8% of the total. Walleye was the most abundant (23.2%) followed by white sucker (16.4%), smallmouth bass (14.0%), shorthead redhorse (11.6%), rock bass (5.2%), and northern hog sucker (4.4%). At both stations combined, walleye, white sucker, smallmouth bass, shorthead redborse, quillback, and northern hog sucker were the most abundant fishes observed and composed 74.9% of the total . These fishes were also the most abundant in 1977 (Buynak et al.1978a) and 1976 (Buynak and Gurzynski 1977a) when they composed 70% and 77% of the total, respectively. Occurrence of the more abundant fishes at each station was similar throughout the 10 months sampled. At SSES (sites EL-1 and EL-2), carp and white sucker were the only fishes observed in all months (Table E-13) . Quillback and shorthead redhorse were observeG Gech month except December, and walleye in all months except April. 0C,.t fl3hes were observed in 4 vs.v.er (19). At Bell Bend (sites April and December (4 each) and most EL-3 and EL-4), quillback and white sucker were th9 enly fishes observed We'E$b.00. 166 in all months (Table E-14). Walleye, northern hog sucker, and fallfish were observed each month except April; carp, shorthead redhorse, and rock bass in all months except December. The number of fishes at Bell Bend ranged from 5 in April to 18 in September. Monthly differences at both stations were influenced by seasonal changes in river level and turbidity. At the four sites, no significant differences were found either in the total number of fishes observed (Q = 2.71; DF = 3) or in species composition (M = 3.67; DF = 3) (Tables E-3 through E-12). The number of fishes ranged from 19 to 22 at the four sites. White sucker, shorthead redhorse, smallmouth bass, and walleye composed 57.9, 63.6, 65.1, and 65.3% of the total observed at EL-1, EL-2, EL-3, and EL-4, respectively. Between SSES and Bell Bend, no significant difference was found in the total number of specimens observed per unit ef fort. At SSES, 2,402 specimens were observed and at Bell Bend, 2,237 specimens were recorded (Tables E-3 through E-12) . In 1977, Buynak et al. (1978a) also found no significant difference in the number of specimens observed per unit effort between SSES and Bell Bend. In 1976, however, significantly more specimens were observed per unit effort at Bell Bend than at SSES (Buynak and Gurzynski 1977a). No significant differences were found in the number of specimens observed per unit effort between the east and west bank sites (Tables E-3 through E-12) at either SSES or Bell Bend. Totals of 1,244 and 1,158 specimens were observed at the SSES east bank site (EL-1) and the west S70170 167 bank site (EL-2), respectively. At the Bell Bend cast bank site (EL-3), 1,209 specimens were observed compared to 1,028 at the west bank site (EL-4).In 1977, however, significantly more specimens were observed at the east bank sites at both stations (Buynak et al. 1978a). In 1976, no difference was found at SSES, but significantly more specimens were observed at the Bell Bend east bank site (Buynak and Gurzynski 1977a). At both SSES and Bell Bend, significantly more (P<0.01; n = 40) fish per unit effort were observed at night than during the day. Totals of 1,835 (day) and 2,804 (night) specimens were observed (Tables E-3 through E-12). In 1977, the number observed per unit ef fort was also significantly greater at night (Buynak et al. 1978a). In 1976, however, significantly more fish were observed at night at Bell Bend, but no differences were found at SSES (Buynak and Gurzynski 1977a). Walleye, an important game fish, showed a marked increase at both stations in relative abundance and number observed per unit effort in 1978 compared to 1976 and 1977 (Buynak and Curzynski 1977a, Buynak et al. 1978a). Its relative abundance increased from an average of 6.0% at SSES and Bell Bend in 1976-77 to 20.9% in 1978. The number observed per unit effort increased from an average of 2.5 walleye in 1976-77 to 12.1 in 1978. More than 50% of the walleye observed in 1978 were young, and most were seen from September through November (Tables E-13 and E-14) . A sample of 13 young, collected on 17 October, ranged in length from 144 to 196 mm and weighed from 24 to 60 gms. These data indicate that a relatively large year class of walleye was produced in 1976. Based on$i0$~0. 168 previous age and growth studies (Ichthyological Associates 1974), most of the surviving individuals of the 1978 year class should enter the sport fishery by 1981. Seining A total of 1,977 specimens of 21 fishes was captured by seine at SSES and Bell Bend (Tables E-2 and E-15 through E-21) . Of the 20 fishes captured at SSES (Table E-22), five composed 90.2% of the total catch. Spotfin shiner was the most abundant (5 7. 3%) followed by spottail shiner (12.0%), bluntnose minnow (7.9%), comely shiner (7.0%), and white sucker (6.0%). At Bell Bend, 16 fishes were captured (Table E-23). The same five fishes, in the identical order of relative abundance as at SSES, composed 86.9% of the total catch. Spotfin shiner was the most abundant (35.4%) followed by spottail shiner (19.3%), bluntnose minnow (12.7%), comely shiner (11.1%), and white sucker (8.4%). Occurrence of the more abundant fishes at both stations was similar throughout the seven months sampled. At SSES (sites SN-1 and SN-2), spottail shiner, spotfin shi.ner, and bluntnose minnow were captured each month (Table E-22) . Fewest fishes were taken in October (6) ; most were captured in June (15) . At Bell Bend (sites SN-3 and SN-4), spotfin shiner was the only species taken each month . Spottail shiner and bluntnose minnow were captured in all months except July (Table E-23) . 87fLI.I 7.0.a 169 The number of fishes captured at Bell Bend ranged from 4 in July to 11 in August. As with data collected by electrofishing, monthly differences at both stations were influenced by seasonal changes in river level and turbidity. At the four sites, no significant differences were found either in the total number of fishes captured (Q = 1.67; DF = 3) or in their species composition (M = 0.82; DF = 3) (Tables E-15 through E-21). The number of fishes ranged from 13 to 16 at the four sites. Comely shiner, spottail shiner, spotfin shiner, bluntnose minnow, and white sucker composed 88.2, 94.5, 87.8, and 86.0% of the total catch at SN-1, SN-2, SN-3, and SN-4, respectively. Between SSES and Bell Bend, no significant dif ference was found in the total number of specimens captured per unit effort. At SSES, 1,465 specimens were captured and at Bell Bend, 512 specimens were taken (Tables E-15 through E-21). Significant dif ferences were not detected in the number of specimens captured per unit effort between SSES and Bell Bend in 1976-77 (Buynak and Gurzynski 1977b, Buynak et al. 1978b). No significant differences were found in the number of specimens captured per unit effort between the east and west bank sites (Tables E-15 through E-21) at either SSES or Bell Bend. At the SSES east bank site (SN-1), 1,008 specimens were capt'tred compared to 457 at the west bank site (SN-2). At Bell Bend, 254 specimens were taken at the east bank site (SN-3) and 258 were captured at the west bank site (SN-4). @/03_70 170 In 1976-77 (Buynak and Gurzynski 1977b, Buynak et al. 1978b), significant differences were not found between the east and west bank sites at both stations.In 1978, the SN-1 site was moved because seining could not be conducted at the original location due to erosion of the river bank. Water at the original location was relatively clear because it was diluted with water from Little Wapwallopen Creek. The river water at the new location, 15 m upriver from the creek mouth, is undiluted and more turbid. Nearly 7-fold more fish were taken at the new location in 1978 compared with the mean catch at the original location in 1976-77 (Buynak and Gurzynski 1977b, Buynak et al. 1978b). The larger catch in 1978 probably occurred as a result of decreased net avoidance because of increased turbidity. A total of four young walleye was captured at SSES and Bell Bend in 1978.Only three young walleye were taken from 1971 through 1977, a period when overall seining ef fort was several fold greater than in 1978. These data support the conclusion in the electrofishing section, that a relatively large year class of walleye was produced in 1978. REFERENCES CITED Bailey, R. M. , J. E. Fitch, E. S . Herald, E. A.

None of the plants are proposed as threatened or endangered. Eleven salt drift transects were utilized in 1978 for observations of phenology and parasitic plant diseases. The greatest number of species flowered in August on forest and field transects, and in July on marsh transects. Twenty-four parasitic plant diseases were observed. Three upland forest plots, two abandoned fields, and one marsh were sampled quantitatively. Data from two forest plots were compared with that collected on the same plots in 1977. Few significant changes were found. The most important species in the abandoned fields were perennial herbs, especially Solidago spp. and grasses. The North Field had a larger number of species present than Switchyard Field due to greater soil moisture. The marsh was dominated by more or less typical marsh species, especially Leevoia oryzoides, Sagittaria latifolia, and Sparganitri ciwycarpum. INTRODUCTION Terrestrial ecological studies were conducted on the Susquehanna SES site f rom 1972 through 1974 (Ichthyological Associates 1973, 1974; Burton 1976) and in 1977 (Montgomery 1978) . The studies begun in January 1977 and continued through 1978, were initiated to gather baseline information on flora and vegetation to compare with information to be collected during the operation of the Susquehanna SES. $/Or303 200 The purpose of the flora and vegetation studies in 1978 was to establish continuing programs that can be used to monitor changes, if any, during the operation of the Susquehanna SES. Systematic information was collected on the phenology of flowering plants and ferns and parasitic plant diseases (ficra), and quantitative information was obtained for sel ced plant communities (vegetation). PROCEDURES Flora Floristic studies were conducted from March through October 1978. As in 1977 (Montgomery 1978) , observations were made on both sides of the Susquehanna River throughout the Susquehanna SES site (Fig. F-1). In addition to general observations, transects for systematic observations were established. These transects were selected for observing possible ef fects of moisture and salt drif t from the Susquehanna SES cooling towers during operation, and are referred to as salt drif t transects. Salt drift transects were located in several plant communities at varying distances and directions from the Susquehanna SES (Table F-1). On each salt drift transect the following data were recorded: all plant taxa in flower (shedding spores for ferns), all parasitic plant diseases observed according to host species, and relative effect of the parasitic disease (i.e. defoliation, major leaf necrosis, minor necrosis, etc.) . 370204 201 Each transect was surveyed once a month, usually in the latter half of the month, March through October. Identifications of vascular plants were made sing Fernald (1950), Gleason and Cronquist (1963), Peterson and McKenny (1968); Wherry (1961) for f erns; and Hitchcock (1950) for grasses. Nomenclature follows Gleason and Cronquist (1963) , except for ferns and fern allies, for which Wherry (1961) is used. Parasitic plant diseases were identified using U.S. Department of Agriculture (1960), Hepting (1971), Westcott (1971), and Pennsylvania Department of Environmental Resources (1975). Because of the confusion of some common names of plants, scientific names are used in the text and in all tables. Common names are given in Tables F-2 and F-3. Species not previously observed on the site were collected and added to the reference herbarium. Uctilago maydis (corn smut) was observed in the cornfield north of the biological laboratory in August. A survey of the incidence of the disease was made by counting the number of plants on which the disease occurred in two randomly selected rows in the cornfield. The survey was made on 29 August. Vegetation Quant'tive vegetation studies were conducted in three upland forests: Council Cup Forest (CC), Township Road 419 Forest (TR419), and quarry Hillside Forest (QH); two abandoned fields: North Field (NF) and Switchyard Field (SwF); and an open marsh: US 11 Marsh (USllM) (Fig. F-1). 370205 202 The three forest plots were sampled in July. The CC Forest was located east of the Council Cup Overlook, in Conyngham and Hollenback Townships, Luzerne County, 3 km southeast of the Susquehanna SES. The study plot was nearly level to a gently east-facing slope, at an elevation of approximately 335 m.The TR419 Forest was located on a steep south-facing hillside above a dirt road (Townsh.p Road 419), just north of the Susquehanna SES fence, in Salem Township, Luzerne County. Elevation ranged from 200 to 250 m. The QH Forest was located on a steep south-f acing hillside east of an abandoned quarry above Route PA 239, in Conyngham Township, Luzerne County. Elevation ranged from 225 to 250 m. The CC Forest and TR419 Forest were sampled in 1977, the QH Forest was sampled for the first time in 1978. The forest areas were surveyed into transects parallel with the long direction of the plot. Points were located along these transects at distances depending on the size of the plot to be covered: 50-m intervals in CC, 75-m intervals in TR419, and 30-m intervals in QH. At each point a 10 x 10-m quadrat was permanently marked for sampling trees and saplings (Cain and Castro 1959), There were 20 quadrats in CC, 24 quadrats in TR419, and 15 quadrats in QH. Trees were defined as 10-cm diameter breast height (dbh) or greater, saplings as 1.0-9.5-cm dbh, and seedlings less than 1.0-cm dbh.All trees and saplings in the 10 x 10-m quadrat were identified, counted, and the dbh measured to the nearest cm with a diameter tape. Two 1 x 1-m quadrats were established in diagonally opposite corners of the 10 x 10-m quadrat for sampling tree seedlings, shrubs , herbs, and 37020G 203 ground cover (litter, moss, rock, and bare soil were defined as ground cover). Plants were identified and an estimate was made of the percent cover in the quadrat for each species, but stems were counted only for tree seedlings. Stems of shrubs and herbs were not counted because many species are colonial, and stem number was judged not to be useful. The following were calculated for trees, saplings, and tree seedlings: er qua as nw ch a species occurs Frequency = n total number of plots frequency f a species X 100 Relative Frequency = total frequency of all species nu ber of stems of a species Density =hectare d nsity of a species X 100 Relative Density = total density of all species asa ar a a species Dominance (trees and saplings) =, where hectare basal area = Tr ( dbh 2 2 Dominance (tree seedlings) = c ver value f a species area sampled in m2 dominance for a species X 100 Relative Dominance = total dominance for all species Importance Value = relative f requency + relative density + relative dominance (maximum value = 300; 970207 204 The following were calculated from the quadrat data for shrubs, herbs, and ground cover (calculated separately for each): Frequency and Relative Frequency = same as above a ver va ue r a species Dominance = area sampled in m' d minance f r species Relat.ve Dominance = X 100 total dominance for all species importance Value = relative frequency + relative dominance Comparisons of 1978 data with that collected in 1977 were made using an analysis of variance with repeated measures design (Sokal and Rohlf 1969). Quadrat by quadrat tests were made using number of stems per quadrat for each tree and sapling species, and percent cover per quadrat for shurbs, herbs, and ground cover. Tree seedlings were not counted in 1977 and 1 x 1-m quadrats were not sampled in TR419 in 1977; therefore, comparisons were not made for these data. Log (X+1) trans-formations for stem numbers and arcsine transformations for percent cover values were made as recommended by Sokal and Rohlf (1969) and Goodall (1970). Two abandoned fields, NF and SwF, were sampled in September and October 1978 (Fig. F-1). NF was located at the north end of a cornfield on the west side of the Susquehanna River, 2 km northeast of the Susquehanna SES, in Salem Township, Luzerne County. Elevation is 153 m. The western edge of the field was wet in spring, but dried by midsummer. This wet part of S70208 205 the field was not included in the sampling area; the remainder of the field was dry except during periods of extremt river flooding. SwF was located adjacent to the Luzerne Eiectric Division, UCI s ub s ta tion, above PA Route 239, 2.8 km east o he Susquehanna SES in Conyngham Township, Luzerne County. Elevation was approximately 210 m. The field sloped gently northward and was entirely dry. The line intercept method was used for sampling (Cain and Castro 1959, Smith 1966). A baseline was established near the parallel to one edge of the field and marked into 10-m intervals. Lines were run perpen-dicular to the baseline at these in t e rvals . Beginning at the baseline, these lines were divided into 10-m transects with permanent numbered stakes.The number of transects per line depended on the width of the field; 3 in NF, 5 in SwF. Fifty-one transects were established in NF. Fifty-five transects were established in SwF, but five were disturbed during construction and not sampled. The first 5 m of each transect was sampled by stretching a metric cape between the stakes marking the ends of the transect. The length of cover to the nearest cm for each taxon along the tape was r~ co rded. Tree seedlings, shrubs, and herbs were e sampled together, but the data were treated separately for each. Species area curves were drawn af ter sampling as a check on the adequacy of the area sampled (Mueller-Dombois and Ellenberg 1974) . The following were calculated for all taxa: number of transects on which a species occurs requency = total number of transects W50ERIQ 206 requ ncy a species Relative Frequency = total f requency of all species X 100 Percent Coverage = c v rage f a species on all transects total length of transects Percent coverage of a species Relative Coverage = X 100 total percent coverage of all species Importance Value = relative frequency + relative coverage The US 11 Marsh was sampled in August. It is located east of US 11 and the railroad, and immediately north of Lake Took-a-while (Fig. F-1), 1.2 km east of the Susquehanna SES, in Salem Township, Luzerne County. Part of the marsh contains standing water at all times; in spring or af ter prolonged rains much of the area is wet. The aspect is of herbaceous plants with a few clumps of shrubs in the marsh and shrubs bordering the open marsh. Two parallel transect lineswre run the length of the marsh. Points were located at 50-m intervals along these transects, and a m quadrat was located at each point. There was a total of 31 quadrats. In each quadrat all taxa were identified, percent cover for each was estimated, and the average height for each was measured to the nearest cm. Ground cover was estimated as in forest plots. Calculation of f requency, relative f requency, dominance, relative dominance, and importance value was done as described for forest quadrat data.9 SVGTd10 207 RESULTS AND DISCUSSION Flora A total of 622 species of vascular plants was observed on the Susquehanna SES site from 1972 through 1974 and 1977 through 1978. This total includes 122 woody plants (Table F-2) and 500 herbaceous plants (Table F-3) . The herbaceous plants include 37 ferns and fern-allies and 463 flowering plants. Fif ty-three species were observed for the first time on the site in 1978. None of the plants observed on the site has been proposed as threatened or endangered by the U. S. Department of the Interior (1975, 1976). No plants are presently listed for Pennsylvania (U.S. Department of the Interior 1979). There was a total of 418 plants observed on the salt drif t transects; 345 on forest transects (Table F-4), 175 in field transects and 112 in marsh transects (Table F-5) . Of the forest transects, QSH (abbreviations are given in Table F-1) had the greatest number of species (196), followed by TR438 (158), TR419 (132), CC (108), RF (91), and GIF (88) . The greatest number of species flowered in August (132), followed by July (115), and May (103) . Most transects had more species in flower in July and August except CC, where more species flowered in May and June. Of the abandoned field transects, TCF had the greatest number of species (99), followed by NF (93), and SwF (81) . The greatest number of species flowered in August ( 73) , followed by July (57), and September (52) . On most field transects the number of species in flower increased through the spring to late summer; there was no spring flowering peak in May comparable to that on forest transects. On the marsh transects, 81 species were observed on k2OM.1 208 US11M and 73 on SM. The greatest number of species flowered in July (30), August (29), and September (25) on US11M; and in August (28), September (20), and June (19) on SM. No species flowered on any transect except QSH in March, and none flowered in either marsh in April. With these exceptions, species were observed on all transects in each month, April through October. A total of 24 parasitic plant diseases was observed on 46 host species (Table F-6) . The powdery mildew, Erysiphe cichoracearum, infected 18 species and the rust, Coleosporium solidaginis, infected 7 species. Twenty-one diseases were observed on QSH, 15 on TR438, and 15 on CC; diseases were observed on all transects. The occurrence of diseases was related to the presence of host species rather than to any observed environmental factors. In the spring, leaf spots were the most prominent, especially on Acer rubrun. In the late summer and fall, rusts, especially of Solidago spp. , and powdery mildews were most abundant. The incidence of corn smut in the cornfield north of the biological laboratory was found to be 2.1%. Of the 2,912 plants examined in two rows, 60 were infected. Plants with corn smut tended to be clumped together in the rows.Vegetation Betula lenta was the most important (highest importance value) tree in the CC Forest (Table F-7) . Quercus velutina, Pinus strobus, O'tercus prinus, Q. alba, and Pinus virginiana were associates. Total density was 620 trees /ha. Betula lenha and Acer rubrum were the most important saplings, w y $6a.t_A < ru o rs 4 209 with Quercus velutina, Q. borealis, and Q. prinus as important associates (Table F-8). Total density was 2,345 saplings /ha. The most important seedlings were Acer rubrum and Prunus serotina, with three species of Quercus of secondary importance (Table F-9) . Total density was 25,750 saplings /ha. Vaccinium pacillans was the most important and only frequent shrub, with smaller amounts of seven other species (Table F-10). Lycopodiwn f7abellifbrme was the most important herb , with 15 other species encountered (Table F-10) . Litter was the predominant ground cover. The same trees were the most important in 1978 as in 1977 (Montgomery 1978). Associates were the same with the addition of Betula populifblia. The only significant change in the tree layer was an increase in Quercus velutina from 1977 to 1978 (Table F-11). The same sapling species were important in 1977 and in 1978. Significant changes in the saplings were decreases in Acer rubiser, Betula populifblia, and Carya glabra; and an increase in Carya tomentosa (Table F-12) . CaFda glabra and C. tomentosa were not distinguished in the 1977 survey and both were reported as C. tomentosa. The decrease in Betula populifblia as a sapling was caused by death of some saplings, and by increase in diameter to tree size of one sapling.Vaccinium pacillans and Rhus radicans increased significantly in cover from 1977 to 1978 (Table F-13) . Lycopodium f7abellifbrme also increased significantly in cover. There were no other significant changes in shrubs or herbs, and no changes in ground cover (Table F-13) . In the TR419 Forest, Quercus velutina was the most important tree, with Pinus virginiana second in importance (Table F-14). Eighteen species were encountered. Total density was 617 trees /ha. Cornus f70rida was the d Of s1 210 most important sapling, uith Quercus vclutina, Acer rubrum, and Carya 6mnentosa as associates (Table F-15). Sixteen species were encountered. Total density was 1,208 saplings /ha. Cornus florida was the most important seedling, with Frarinus ancricana nearly as important (Table F- 16) . Prunus serotina and Accr rubrum were important associates. Fourteen species were encountered. Total density was 88,541 seedlings /ha. Vines, including Parthenocissus quinquefolia, Vitis aestivalus, and Rhus nadicans were important in the shrub layer (Table F-17) . Rubus allegheniensis, Vaccinium vacillans, and V. stanincum were also important. Eleven species were encountered. Dennstaedtia punctilobula was the most important herb (Table F-17) . This species had high density in only three quadrats. Caver suannis and Solidago caesia were the mos t frequent herbs. More than half of the 48 herbs encountered occurred in only one or two quadrats, indicating the small numbers of herbs present in the forest. Litter was the predominant ground cover. The same tree species were most important in 1977 as in 1978, and there were no significant changes in trees (Table F-18). Tree density increased from 576 trees /ha (Montgomery 1978) to 617 trees /ha in 1978. The same sapling species were most important in 1977 as in 1978, and there were no significant changes in saplings (Table F-19). Sapling density also increased,from 1,183 to 1,208 saplings /ha. Tree seedlings, shrubs, herbs, and ground cover were not sampled in 1977. The QH Forest was sampled for the first time in 1978. Qucrcus velutina was the most important trec , with Frarinus americana, Qucreus prinus, Acer rubrum, and Quercus borealis as important associates (Table F-20). Seventeen S/0214 211 species were encountered. Total density was 653 trees /ha. Cornus florida was the most important sapling, with Acer rubrum, Fradnus ancricana, and Quercus borealis as associates (Table F-21) . Seventeen species were encountered. Total density was 1,667 saplings /ha. Fraxinus americana was the most important seedling, with Cornus florida and Acer rubrum as associates (Table F-22) . Seventeen species were encountered. Quercus velutina and Q. prinus were less important as saplings and seedlings than as trees. Fradnus a~ericana, Acer rubrum, and Quercus borealis were about equally important in all three size classes, and should become more important as trees as the forest matures. Cornus florida, important as a sapling and seedling, is an understory tree that seldom reaches canopy size (Braun 1950). Parthenocissus quinquefolia was the most important shrub; other species were much less important (Table F-23) . Aster divaricatus was the most important herb. Deschampsia flexuosa and Dryopteris marginalis were also important. Thirty-six taxa were encountered. Litter was the most important ground cover. The QH Forest was similar to CC and TR419 in the importance of oaks, especially Quercus velutina. Pinus virginiana was less important in the QH Forest, and Pinus strobus occurred only as a seedling. Fraxinus americana was more important in the QH Forest. Ten species of trees were common to QH and CC, and ten species were corcmon to QH and TR419 (not the same ten, however) . Vines were important in QH and in TR419. Herbs were infrequent in QH, as in CC and TR419. Of the five most important herb species in QH, two were found in CC, but were not among the most important l0Sjj] 212 species. A total of four species (11.1%) found in Qll were found in CC. Of the five most important herb species in QH, three were found in TR419, and two (Carex cuannii and Solidago caesia) were among the five most important species. Nineteen species (52.8%) found in Qll were found in TR419. Thus, Qll more closely resembles TR419 floristically; they are also on similar slope and exposure. In NF, 97 taxa were encountered, of which 83 were herbs, 6 were tree seedlings, and 8 were shrubs or woody vines (Table F-24). /Mzlenbergia frondosa, Solidago canadensis, S. graminifolia, Agrostis sp. , and Aster ericoides were the mos t important herbaceous species. Seven additional species, including two species of Solidago, occurred with frequency greater than 50%. Although most species were typical of abandoned fields in the area, the diversity (number of species per unit area) is high. Zhis is accounted for by the addition of elements from the river forest (e.g. Lysimachia ciliata, Boehmeria cylinidrica, Leersia virginica, Impatiens biflora, etc.) and from wet open habitat (e.g. Epilobium coloratum, Verbena hastata, Lycopus americanus, Eupatorium perfc:iatum, etc.). seedlings of six tree species were encountered (Table F-24); all were found as mature trees in the nearby river forest. Eight shrubs were found with Rubus allegheniensis the most important. The high dominance of Rubus allagheniensis (sevt.ath among all species in the field) was due to the occurrence of large clumps of this plant in certain areas of the field. 37021G 213 In SwF, 74 taxa were encountered, of which 57 were herbs, 8 were tree seedlings, and 9 were shrubs (Table F-25) . The most important herb taxa were Solidago rugosa, S. canadensis, grasses, Potentilla simplex, and Rumex acetosella. Nearby all of the herbaceous taxa were typical old field perennials or bienutals. Seedlings of eight tree species were found. Most of these were typical of upland forests; all except Acer saccharinum and Ulmus ancricana were found in TR419. Eight shrub species were encountered, with Cbrnus racemosa the most important. The shrub species were also typical of old fields in the Susquehanna SES area. Of the 97 taxa from NF, 41 were found in SwF (42.0%), including 34 herbaceous taxa (41.0% of the herbs) . Of the 74 taxa from SwF, 55% were found in NF. The larger number of species in NF is due to greater soil moisture which allows marsh and river forest species to grow in this field. Both fields were dominated by typical old field species, especially Solidago spp.; Sdlidago spp, accounted for a total cover of 42.7% in NF and 72.2% in SwF. Tree seedlings were frequent and had greater cover in SwF t.han NF. Shrubs were more f requent in SwF, but had greater total percent cover in NF. Total percent cover by trees and shrubs is low (less than 15.0%) in both fields. In the US 11 Marsh, Leersia oryzoides, Sagittaria latifolia, Sparganium eurycarpum, and Solidago gigantea vere the most important species (Table F-26) . Fifty-seven taxa were encountered, including one tree seedling and three shrubs. Analysis of height measurements (Table 3/OM.7 214 F-26) indicated that there were at least three indistinct layers of vegetation in the marsh. The four species given above, plus Juncus effusus, Carex scoparia, Scirpus cyperinus, and Phalaris arundinacea were important herbs more than 50 cm tall. Most of the plants in this layer were grass-like, with elongate narrow leaves (Sagittaria latifolia was an exception) . Below this layer were shorter herbs, many of which have broader leaves; the most important species in this layer were Eleocharis tenuis, Galiwn trifidum, Onoclea sensibilis, Polygonwn sagittatum, and Boehmcria cylindrica. Close to the ground (or water) was another layer of herbs, including Lemna minor, Pilea pumila, Eleocharis acicularis, and Selaginella apoda. Seedlings of other taxa, especially Leersia cryzoides, occurred in this layer also. None of the layers was distinct, but all quadrats except those in open water contained 'several layers of vegetation. Shrubs and tree seedlings were encountered infrequently (Table F-26). Ground cover was mostly litter (actually peat), with water second in importance. Observations indicated that the relative amount of water and exposed peat varied with the seasons. The time of sampling, in August, was a period of low water. 370218 215 REFERENCES CITED Braun, E. L. 1950. Deciduous forests of eastern North America.

A species of one new family, Alaudidae, was observed bringing the total number of families observed to 44. Seasonal censuses were conducted on two wooded plots, one abandoned field plot, and one march plot. A total of 30 species was observed in winter, 96 in spring, 68 in summer, and 90 in fall. Density of individuals increased from winter through fall on all study plots except the marsh. The total number of species was higher during spring and fall, and lower in winter and summer on all plots e:. cept the abandoned field. Nineteen species of waterfowl were observed during the spring migration. The " endangered" peregrine falcon was observed migrating over the Council Cup Forest on 3 November 1978. Breeding bird censuses revealed that 32 species maintained territories un the four plots. A total of 82 birds impacted on the Unit 1 Cocling Tower and Meterological Tower in September and October 1978. 37073E3b 253 INTRODUCTION Preliminary studies of the bird life on the Susquehanna SES site were begun in 1971 and terminated in 1974. During this period the literature was surveyed, a species list was compiled, and the relative abundance of resident and transient species was monitored (Ichthyological Associates 1973, 1974; Burton 1976). The current preoperational studies were begun in January 1977 to gather information on bird numbers, behevior, occurrences, and habitats during final construction of the Susquehanna SES (Ruhe l??8) . These baseline data wil.1 be compared with similar information collected after the station begins operation in 1981. In addition, bird impaction on the Susquehanna SES cooling and meterological towers was investigated to provide bird mortality data during the 1978 fall migration. PROCEDURES Four study plots (Council Cup Forest, CC; TR419 Forest, TR419; US 11 Marsh, US11M; and Switchyard Field, SwF) were censused during 1978; SwF was first censused in 1978 (Fig. F-1). Both CC and IR419 were wooded, US11M was a freshwater marsh, and SwF was an abandoned field. Criteria considered in selection of the plots were:

1) the vegetation be representative of the Susquehanna SES; 2) the areas remain relatively undisturbed throughout construction; and 3) the plots be a minimum of 6 ha of uniform habitat (Hall 1964).

970U7 254 All plots were surveyed and measured using a Brunton pocket transit on a tripod and a 30-m engineer's tape. The boundaries of each plot were marked with flagging. Transect lines were surveyed within each plot at distances dependent upon vegetation density. Transects provided coverage of all parts of the plots when sampling by the strip census method (Kendeigh 1961) . A polar planimeter was used to calculate plot areas. All bird observations were checked against the federal endangered and threatened species list (U.S. Department of the Interior 1979) and the American Birds blue list (Arbib 1977) . The species named to the blue list are those which "have recently or are currently giving evidence of population declines, either regionally or continent-wide" (Arbib 1977) . Nomenclature follows American Ornithologist's Union (1957) . Seasonal Census The seasonal censuses were designated and conducted according to the following timetable: winter,16 December-28 February; spring, 1 March-15 May; summer, 16 May-31 July; fall, 15 August-30 November. Time and weather conditions were recorded at the beginning of each census and the time noted at the conclusion. Winter, spring, and fall censuses were begun prior to 0800 h and summer censuses started one-half hour before sunrise. The observer slowly walked along transects in such a manner as to cover all sections of the plot with a minimum of overlap. All species were identified by either sight or vocalization. In the laboratory, the data were transferred to bird census code sheets for computer input. S70258 255 A minimum of five censuses were conducted in each plot during each season, Censuses were not conducted during periods of inclement weather, such as heavy rains or high winds. Breeding Bird Census The four study plots were censused eight times between 1 May and 15 July. Each census began within 30 minutes before sunrise, a period that coincides with the beginning of intense singing by most passerines (Hall 1964) . Starting locations were altered on t cb plot from census to census to minimize bias that might result from changes in singing intensity. During each census, the locations of singing males were marked on a daily census map. All birds were identified and recorded with a symbol that designated species and behavioral activitv (i.e. singing, aggression, nest building, etc.) . Censuses were not conducted during periods of high winds or heavy rains. These data were analyzed by " territory mapping" described by Hall (1964) and Oekle (1967) . After a census, data on the daily census map were transferred to a similar map for each species. The number of territories for a species was then estimated by counting the clusters of daily census points on the species map; each cluster represented a territory. For each species, mean density (number of territories /km ) and relative density (number of territories of one species / total number of territories of all species) were calculated. 370259 256 River Etrd Survey Migratory waterfowl and other water associated birds were censused weekly in the spring from a boat on a 16-km section of the Susquehanna River. The survey route extended from the Shickshinny-Mocanaqua Bridge to the Berwick-Nescopeck Bridge. The identity and number of birds observed on each survey were recorded. Each survey was begun between 0800 and 1000 h and lasted about 2 hours. Results were formulated as indices of river usage, i.e. birds /km and waterfowl-days (average number of Anatidae observed for two consecutive surveys X the number of days between surveys) . Conditions limiting surceys were low river levels (surface elevation <l49.5 m above mean sea level) and hazardous river conditior.s such as ice floes and flooding. No fall 1978 surveys were conducted due to the low river levels which made navigation impossible along most of the route. Bird Impaction In 1978, bird impaction studies were conducted on and around the nearly completed Unit 1 Cooling Tower and the Meterological Tower (met tower) from 1 September through 31 October. The height of the cooling tower was 152 m and that of the met tower was 91 m. Searches for impacted birds were conducted daily, Monday through Friday, excluding holidays. The circumference of the cooling tower, both inside and outside, was searched in the morning beginning approximately 1 hour prior to the start of construction. The ground around the met tower was checked from the base out to a distance of 50 m, including the area under the guy wires. 370260 257 All birds at each location were collected and identified. The location of each specimen was recorded with reference to the compass direction from the center of the respective tower and the position from the tower (inside or outside of the base of the cooling tower, or distance from the base of the met tower) . Weather conditions were recorded during each search and augmented with data collected at the met tower or by the National Oceanic and Atmospheric Administration (NOAA 1978) for the 12 hours previous to the search. RESULTS AND DISCUSSION A total of 210 species of birds was observed near the Susquehanna SES from 1972 throust 1974 and 1977 through 1978 (Table G-1) . During 1978, 185 species were observed on 6e site. Fifteen of these species had not been reported during previous years. One new family, Alaudidae, was observed bringing the total number of families observed to 44. The following families composed 48.6% of the species observed in 1978: Parulidae (28 species) 15.1%, Fringillidae (25) 13.5%, Anatidae (21) , 11.4%, Scolopacidae (8) 4.3%, and Tyrannidae (8) 4.3%. One endangered species, peregrine falcon, was observed flying over CC on 3 November 1978. Twenty-one blue-listed birds were observed during the year. Ten were seasonally migratory, seven were summer residents, and four were year-round residents (Table G-1) . O Ok*-e V 258 Seasonal Census Winter A total of 30 species was observed during winter on the four study plots (Table G-2) . The US11M supported 22 species; CC, 13 species; TR419, 7 species; and none were observed on SwF. The US11M also supported the highest density of individuals in any of the plots. The majority of the winter communities was composed of species in the family Fr!ngillidae (Table G-2) . Tree and song sparrows were the most abundtnt species in US11M, the dark-eyed junco in C;, and the golden-crowned kinglet in TR419. The downy woodpecker, black-capped chickadee, and blue jay were the only species to be observed on the three plots where birds were observed. Densities of most species remained stable throughout the winter, except during a cold spell from 27-31 January when the temperature never exceeded-3.3 C, vinds averaged 32 kph (NOAA 1978), and 2.5 cm of snow fell. Throughout this period, there was a 34% decrease in densities in the Us11M and a 38% decrease in densities in CC. No data were collected in TR419 during this period. Spring A total of 94 species was observed on the study plots during spring (Table G-3) . In TR419, 47 species were observed; CC, 46 species; US11M, 40 species; and 16 species in SwF. The black-capped chickadee was the most abundant species in TR419. The pine grosbeak was the most abundant 370262 259 in Jr. the red-winged blackbird in US11M, and the field sparrow in SwF. The US11M supported the highest density of individuals than the other plots.The arrival of most species was from one to two weeks later than last year (Ruhe 1978) . The colder than normal temperatures in March through May (NOAA 1978) probably delayed the migration. Warbler migration began on 3 May and lasted into the early summer. From 16-25 May, the largest concentrations of warblers passed through the study plots; a total of 19 species was observed. Warblers composed 36.9% of the 12 May census in TR419 and 60.0% of the 16 May census in CC. On 13 May, warblers were found in the greatest concentrations in SwF and US11M. They composed 46.6% of the census in SwF and 21.4% of the census in US11M. The wood thrust migration peaked on 10-12 May. Black-capped chickadees were abundant all spring in TR419 but decreased in CC af ter 18 April. Robins first appeared on 12 April as did field sparrows. Tree sparrows were last observed on 10 March. Most stadpipers and yellowlegs were observed on 8 and 13 May. Summer A total of 68 species was observed during the summer (Table G-4) . In TR419, 45 species were observed, 37 in CC, 26 in US11M, and 17 in SwF. As during the previous seasons, the US11M supported greater densities than the other study plots. Spring migration continued into the summer census period. Migrant species were observed as late as 25 May. The wood thrush was most abundant in TR419, the scarlet tanager in CC, the red-winged blackbird in US11M, and the field sparrow in SwF. WO263 260 There were changes in populations of several species over the 1977 densities. A noticeable increase of brown-headed cowbirds was observed on the wooded plots from the mean densities of 1977 (Ruhe 1978). This parasitic species may cause decreases in songbird populations (Bent 1963, 1965). Other species that increased in density were great-crested flycatcher, eastern wood pewee, veery, and cedar waxwing. There was a decrease in black-capped chickadees on the wooded plots. In the marsh, only the indigo bunting decreased in number, 5 species remained at approximately 1977 levels, and 13 species increased in numbers. Fall A total of 90 species was observed on the four study plots during the fall migration season (Table n-5). The TR419 supported the greatest number of species, 53; followed by US11M, 40; CC, 39; and SwF, 19. The white-throated sparrow was the most abundant species in TR419, song sparrow in US11M, black-capped chickadee in CC, and European starling in SwF.The peak period of fall migration occurred between 20 September and 18 October. Peak days were 27 September in SwF and US11M, and 10 October in CC, and TR419. Marsh and field speci s migrated through earlier than species associated with woodlands with the exception of the Parulidae. Twenty-two species of warblers were observed during the fall migration. The majority migrated through the wooded plots between 12-20 September, and composed 40.0% of the individuals ,, resent. Warblers were seen in their 07020$ 261 largest concentrations in SwF and USllM between 13-27 September, at which time they composed 22.0% and 5.8% of the total individuals present, respectively. The populations of warblers, for the most part, were greater than they were in 1977 (Ruhe 1978). Only the ovenbird and yellow-rumped warbler populations decre, sed from 1977. Seasonal Population Comparisons Certain general trends and relationships in numbers of species and densities were found among the study plots. From winter through fall, the density of individuals increased in each season on all plots except the USllM (Fig. G-1) . During the same period, the total number of species for the season was higher during spring and fall and was lower in winter and summer except in owF. During the winter, the total community density was low because there were fewer species present than in other seasons. Food quantity is a limiting factor in the winter, therefore, competition becomes acute at a lower population density (Kendeigh 1961). As spring migration proceeded, both density and number of species increased. During the summer, the number of species present was less than the total number of species observed during spring migration, but, because reproduction occurred, the total summer densities surpassed those of the spring migration. Fall migration resulted in an increase in number of species and density brought about by the influx of both adult and young-of-the-year individuals. $50$$b 262 Breeding Bird Census A total of 32 species, representing 12 families, was observed on all four census plots (Table G-6). The highest number of species (19) found in TR419, while US11M supported the most nesting territories was (45.5). The ovenbird, wood thrush, field sparrow, and red-winged blackbird maintained the most territories in CC, TR419, SwF, and US11M, respectively. The families Tyrannidae, Parulidae, and Paridae composed 42.8% of the total species in CC. The families Parulidae and Fringillidae composed 31.6% of the total species in TR419 and 88.9% of the species in SwF. The Fringillidae composed 40.0% of the total species in US11M. Two broods of mallards and one brood of wood ducks were raised in US11M and the surrounding wetlands. The nesting sites, however, were not discovered. Comparisons between the two wooded plots indicated some changes in their breeding populations from 1977 to 1978 (Ruhe 1978) . Of the total species observed in CC, 93.0% were also seen in TR419, but only 68.0% of the species observed in TR419 were observed in CC in 1978. This was a slight increase from the approximately 65.0% shared in common in 1977. The wood thrush was the most abundant breeding species in TR419 as in 1977. The bluejay and black-capped chickadee were next in abundance in 1977, but there was an 82.0% and 56.0% decrease in their populations, respectively. In 1978, the scarlet tanager was second in abundance in TR419. In CC, the wood thrush decreased 43.0% from 7 to 4 nesting territories and dropped

WODR, 263 from the most abundant in 1977 to the second in abundance in 1978. The ovenbird increased in abundance from 5 to 6 nesting territories and was the most abundant nesting species in CC in 1978. These changes may not be significant. Balda (1975) noted that bird densities between years may vary as much as 80% for some species in study plots not physically altered between breeding seasons.

For the four plots combined, there was an increase of six breeding species from 1977. Red-breasted nuthatches were observed nesting for the first time in both CC and TR419. The Susquehanna SES site is a southern extension of this species normal breeding area (personal communication, Chandler S. Robbins, U.S. Fish and Wildlife Service, Laurel, Maryland) . River Bird Survey of the 34 species observed during the spring migration (Table G-7), 74.3% of the total number of individuals passed through the area between 22 March and 12 April. The greatest number of individuals (418) was observed on 29 Mr_cn and the highest number of species (19) was seen on 5 April. The Csnada goose was the most abundant waterfowl observed, followed by the mallard, and the wood duck. Of the nonwaterfowl, the ring-billed gull and Bonaparte's gull were the most abundant. Common mergansers composed from 30 to 90% of the early waterfowl populations in February and early March. By 15 March, black ducks, wood ducks, ring-necked ducks, and hooded mergansers began to arrive. On 22 and 29 March, u.~;r,ru n I o# # L IA"d i 264 large numbers of Canada geese and wood ducks composed over 50% of the birds observed. Flights of Canada geese were heard migrating during the evenings of 20 and 21 March. While standing on the river bank,1,300 were observed from 0700 to 1100 h on 23 March. Large numbers of geese continued to migrate through until 12 April. Ring-billed gulls were present during the latter half of March and April and Bonaparte's gulls were observed in late March and early April. On 27 April and 22 May, osprey and spotted sand-pipers were the most abundant nonwaterfowl on the river, respectively. There was an increase in mean numbers of spring migrants from 60.0 in 1977 (Ruhe 1978) to 183.1 in 1978. The index of birds /km (11.4) and the number of waterfowl-days (10,819) both increased about 2-fold during the same time period in 1978 compared with 1977. Bird Impaction Census During the observation period,1 September through 31 October, 80 individuals impacted on the cooling tower, and 2 individuals were found at the met tower (Table G-8). A total of 17 species of 4 families was found.The two most frequently collected species at the cooling tower were the red-eyed vireo (16) and the bay-breasted warbler (10) . The highest incidents of impaction were found at the cooling tower on 13 and 14 Septcmber when 27 and 13 birds were collected, respectively. Most of these impactions (81.2%) occurred in September, with 51.2% of the total occurring from 11 to 14 September. The two individuals that collided with the met tower were a rose-breasted grosbeak on 14 September and a prarie warbler on 25 September. No endangered or threatened species were found.MO2bb 265 Local weather conditions have been reported to int rease bird mortality on meteorological towers (Kemper 1964, Avery et al. 19 ", 7) . Useally such conditions consist of overcast skys, of ten with precipitation; winds favorable for migration; and f n the fall, the passage of cold fronts (Brewer and Ellis 1958) . Avery et al, (1977) observed that in the fall in North Dakota, Fringillidae and Parulidae were killed in significantly greater numbers on overcast nights with northeasterly winds. At the Susquehanna SES, 66.6% of all birds found impacted on overcast nights with northeasterly winds. Fringillidae and Parulidae composed 81.5% of the birds found under these conditions. Of all the losses, 51.6% were found the morning af ter the passage of cold fronts, which is in agreement with Tardof f and Mengel (1956) and Laskey (1960) . The impact mortality on the cooling tower and met tower at the Susquehanna SES was very low compared to data collected at other towers in the United States. One day kills have ranged from 23-69 birds (Avery et al. 1977) , 133-636 (Crawford 1978), to as high as 15,000 (Kemper 1964) . Bellrose (1971) observed that small passerines migrate on a broad front with the majority flying at altitudes of 152-457 m above ground level (agl) . Currently, the Unit 1 Cooling Tower is 152 m ag1; when completed, it will be 158 m ag1. The cooling tower for the Susquehanna SES, when completed, will exceed the highest local terrain elevation by about 40 m. The top of the tower is well below the observed altitude utilized the most of ten by migrant birds. If birds migrate along the river valley, the tower will extend 6 m above the 152 m agl minimum altitude listed by Bellrose (1971): therefore, most migrant birds should pass over the tower. 1/02b3 266 Additional Animal Observations Although systematic surveys of terrestrial biota other than birds and plants were not made, observations of unusual occurrences of species not previously reported from the Susquehanna SES site, especially those listed as threatened or endangered, were recoroad in field notes. Four such observations were made in 1977 through 1978. An eastern hognose snake (Heterodon platyrhinos) was observed on the QSH salt drift transect (Table F-1) on 30 March 1977. This species is listed as " status indeterminate (apparently threatened or uncommon to rare, but insufficient data currently avtilable on which to base a reliable assessment of status)" by the Pennsylvania Fish Commission (1978) . The snake was observed in an area not presently disturbed by construction. Three species of mammals were observed and added to the species list for the Susquehanna SES site. None of the species are listed as endangered or threatened by the Pennsylvania Fish Commission (1978) or the U.S. Department of Interior (1979) . Black bear (Ursus anericanus) tracks were observed on 27 April 1977 in a tilled field adjacent to North Field (Fig. F-1). The animal was not seen. One southern flyicg squirrel (Claycomys volans) was observed on a bird feeder at the Susquehanna SES Biological Laboratory on 7 December 1978. A mink (Nhstela vison) was observed on 11 December 1978 in the canal near Lake Took-a-while. This was the first sighting of a mink, but tracks have been observed since 1977. !J70T/0 267 REFERENCES CITED American Ornithologist's Union. 1957.

Lymphocystis disease in walleye (Stinostedian vitraum) captured in the Susquehanna River. Proc. Pa. Acad. Sci. 52(1): 49-50. Seasonal variation in the incidence of lymphocystis tumors in 272 walleye, Stinostedfor' vitreum, f rom the Susquehanna River was investigated in 1975 and 1976. The incidence of infection was significantly higher (P<0.01) during the winter and the highest incidence (31%) occurred in February. Most tumors (53%) were on the body below the spinous dorsal fin. Lymphocystis did not occur in fish younger than three years old. Buynak, C. L. and A. J. Gurzynski. 1978. Age and growth of smallmouth bass (Micropterus dolomieui) in a large river polluted by acid mine drainages. Proc. Pa. Acad. Sci. 52(2): 176-178. Growth rates of smallmouth bass (Micropterus dolomieui) collected in the Susquehanna River at SSES (heavily polluted by acid mine drainage) and Falls, Pennsylvania (slightly polluted) were studied in 1976. Ninety percent of the specimens collected were between 2 and 5 years old; the oldest was 8 years. No significant difference in growth rates was found between males and femalee. At both stations, growth rates were similar and most rapid during the first 2 years, but in 3- and 4-year-old fish, growth at SSES was significantly slower (P<0.05) than at Falls. The difference was probably due to a scarcity of food that resulted from mine drainage pollution. Buynak, G. L. and H. W. Mohr, Jr. 1978. Micro-projector for drawing larval fishes. Prog. Fish-Cult. 40(1): 37-38. This paper describes a technique which can be used to obtain good quality illustrations of larval fish with relative ease. With this method, dorsal, ventral, and lateral views of various sized fish ranging from newly hatched through early juveniles can be drawn. The major advantages of using the micro-projector technique are:

1) a person with limited artistic talents can quickly. make well-proportioned drawings; 2) the illustrations can be drawn at different sizes, depending on the magnification of the objective; and 3) the equipment is portable and can be used in a limited space.(This abstract was not I resented in the paper) .

WOM1 -288 Buynak, G. L. and H. W. Mohr, Jr. 1978. Larval development of the northern hog sucker (Hypentelium nigricans) from the Susquehanna River. Trans. Am. Fish Soc. 107(4) : 595-599. Northern hog sucker (Hypentelium nigricans) eggs hatched in 10 days at a mean temperature of 17.4 C. Newly hatched larvae measured from 9.0 to 10.6 mm total length (TL) with a mean of 10.0 mm (standard or notochord length ranged from 8.7 to 10.1 mm with a mean of 9.6 mm). The newly hatched larvae were melanophore-free and had heads that were decurved over a bulbous yolk sac.They had slightly upturned urostyles, pectoral fin buds, and incomplete mouths. Throughout the protolarval phase, they remained relatively melanophore-free. In mesolarvae 15.8 mm TL, an almost triangular patch of melanophores was apparent on the occipital region and was separated f rom more anterior pigmentation by a melanophore-free area between the eyes. Similar pigmentation was found in metalarvae. Fin rays were visible in caudal, pectoral, dorsal, anal, and pelvic fins by 12.0, 12.6, 15.8, 17.8, and 17.8 mm TL, respectively. Trans-formation to mesolarval phase occurred by 12.0 mm TL, to metalarval phase by 19.8 mm TL, and to the juvenile period by 27.8 mm TL. Useful characteristics for distinguishing sucker larvae in the Susquehanna River are flexed urostyles in p rotolarvae , size, and pigmentation patterns. Buynak, G. L. and H. W. Mohr, Jr. 1978. Larval development of the redbreast sunfish (Lepomis auritus) from the Susquehanna River. Trans. Am. Fish. Soc. 107(4): 600-604. A redbreast sunfish (Lepomis auritus) nest with eggs was found in the Susquehanna River near Berwick, Pennerlvania. At hatching, the total length (TL) of the larvae ranged from 4.6 to 5.1 mm with a mean of 4.9 mm (standard or notochord length ranged from 4.5 to 5.0 mm with a mean of 4.8 mm) . Newly hatched larvae had incomplete mouths, large ovoid yolk sacs, pectoral fin buds, and straight urostyles. Pigmentation appeared on the dorsal surface of the head in 7.8-mm TL larvae. The caudal fin rays began to develop by 7.8 mm TL; dorsal, anal, and pectoral fin rays began to develop by 8.1 mm TL; and the pelvic fin rays by 15.0 mm TL. Transformation to mesolarval phase occurred by 7.8 mm TL, to metalarval phase by 11.8 mm TL, and to the juvenile period by 19.0 mm TL. Useful characteristics for distinguishing redbreast sunfish larvae in the Susquehanna River are their larger size at hatching and swim-up, massively coiled gute. and the elongated patch of 20-30 melanophores on the venter between the opercle and vent. fg& 289 Buynak, G. L. and H. W. Mohr, Jr. 1978. Larval development of the white sucker (Catostomus commeroni) from the Susquehanna River. Proc. Pa. Acad. Sci. 52(2): 143-145. White sucker (Catostemus commersoni) eggs hatched eight days after fertilization at a mean temperature of 14.3 C. Total length (TL) of newly hatched larvae ranged frca 8.7 to 9.2 mm (i = 8.9 mm); standard or noto-chord length ranged from 8.5 to 9.2 mm (R = 8.7 mm). The newly hatched larvae were unpigmented, had pectoral fin buds, straight urostyles, and incomplete mouths. Transformation to the postlarval phase occurred by 14.4 mm TL and to the late postlarval phase by 17.9 mm TL. Useful characteristics for distinguishing white sucker larvae in the Susquehanna River are the straight urostyles, size, pigmentation patterns, and preanal myomere count. Deuts h, W. G. 1978. Lornaca cyr.rfnacca on two catostomid fishes. Proc. Pa. Acad. Sci. 52(1): 57-59. The parasitic copepod, Lcrnaca cyprinacca, occurred on 66% of white sucker (Catostomus commersoni) and 32% of quillback (Carpiodes cyp 2inus) collected in the Susquehanna River from June through November 1973. Number of copepodids was high on both fishes from August through October (in September, 90% of white sucker were infected), but declined sharply with river temperature in November. Infection rates of adult copepods were highest in November (64% of white sucker, 27% of quillback), when parasite reproduction was interrupted. Intensities of copepodids ranged from 1 to 104/ host (i = 10/ host) on white sucker and from 1 to 5/ host (i = 2/ host) on quillback; those of adult copepods varied from 1 to 28/ host (R = 4/ host) on white sucker and from 1 to 2/ host (R = 1/ host) on quillback. 'I..e gills of white sucker were infect d more frequently than the body surface or any fin; only the gills of quillback were infected. 5/02T4 290 Gale, W. F. and G. L. Buynak. 1978.Spawning frequency and fecundity of satinfin shiner (Notropis anclostanus) -- a fractional, crevice spawner. Trans. Am. Fish. Soc. 107(3): 460-463. Satinfin shiners (Notropis analostanus) proved to be fractional spawners and pairs of them in outdoor wading pools spawned up to 11 times between June 3 and August 11,1977 (totals 381 to 3,268 eggs per pair) . They released from 6 to 634 eggs per fish per session at intervals of 3 to 31 days (mean 7.6 days; modes 5 and 8 days). Spawning behavior was similar to tlat of spotfin shiner (Notropis spilopterts). Overall, eggs averaged 1.5 mm in diameter. Significant differences (P<0.001) were found in the size of eggs spawned by different females. Eggs in the first spawn were significantly (P<0.001) larger than those in the last spawn. Spawning occurred during the day and activity was most intense between 0600 and 1000 h. Only 12.2% of the 7,290 eggs were spawned af ter 1200 h. Gale, W. F. and H. W. Mohr, Jr. 1978 Larval fish drift in a large river with a comparison of sampling nethods. Trans. Am. Fish. Soc. 107(1): 46-54 Larval fish drif t in the rocky-bottomed Susquehanna River (northeastern Pennsylvania) was investigated during 1974-1975. Near SSES (Susquehanna Steam Electric Station) at least 18 species of drifting larvae were collected by nets mounted on a stationary boat or by pumping. Maximum densities of 15.4 and 27.1 larvae /10 m3 were found in June 1974 and 1975, respectively. Quillback, Carpfodes cyprinus (56%), minnows (25%), and carp, Cyprinus carpio (14% of the total) were the most abundant larvae caught in 19 74 by pumping. The few larvae that drif ted during the day were mostly near the bottom. Large numbers of quillback, white sucker (Catostomus commersoni), shorthead redhorse (Noxostoma macrolepidotum), and tessellated darter (Etheostoma alms tedi) larvae drif ted near the river curface at night. Drift was maximum at about 2400 h. Overall, the day / night drif t ratio was 1/3.8. In 1974 at Falls, the control station upstream of TES and several intervening coal mine effluents, maximum density of dritting larvae was 1.4 3 fish /10 m , less than 10% of that at SSES. Density of spawning-sized fish was about threefold higher at Falls than at SSES. Boat-mounted nets and the pump sampler had equal sampling e fficiencies . Condition of larvae in pump samples was related to net material, mesh size, net shape, and pumping duration. Larvae in best condition were in 5-min samples pumped into slender nets (mouth / length ratio 1/10) .aade of fine-meshed monofilament nylon.(j!/02.N 291 SCIENTIFIC PUBLICATIONS BY THE STAFF OF THE SUSQUEHANNA SES BIOLOGICAL LABORATORY, 1974-78 .Gale, W.
