SUMMARY

l report presems the 1989 results of Commonwealth Edison Company's (CECO) Fish and

. Am'monas hydrophila Monitoring Program conducted in the Rock River near the Byron

m. .rting Stat . The objective of this program is to determine whether station operations

.aving a measurable effect on the fishery of the Rock River. Studies conducted in 1989

! .; valuation of epizootic occurrences of Acromonas hydrophila in channel catfish an in the monitoring of the fish community of the Rock River. The fisheries 4 .

un collected preoperational data from 1975 through 1979 (Espey, Huston

~

3 ic.1976-1980). Sampling was then discontinued until 1983. The fisheries

. . },rogram was reactivated in 19S3 and has been conducted yearly since that date

. 21; EA 19S5,1986,1987; LMS 19S8,1989). The occurrence of Acromonas 1 A. .y infection in channel catfish has been monitored yearly since 19S3.

g

, r...cipal objectives of the fisheries monitoring program were to (1) document the l

oc arrence ofA cromonas hydrophila in channel catfish, and (2) determine species composition

, and relative abundance of fish found within each of the various sampling locations in the

. Rock River near the Byron Station. The sampling methods employed in 1989 included electrofishing and slat. trapping.

Carpsucker spp. (15.69). bullhead minnow (13.0%). spottail shiner (12.4%). shorther.a ,

redhorse (10.0G). golden redhorse (9.iG). spotfin shiner (6.7G). and smallmouth bass (5.4G) were the most common species collected in the 19S9 electrofishing collections. The 1989 electrofishing catch-per-effort (CPE) of 351.0 fish /hr is substantially greater than any CPE reported prior to 19SS (i = 124.7 fish!hr). The high CPEs reported in 1989 were primarily the result of species belonging to the cyprinid (42.2%), catostomid (40.3%), and centrarchid (12.7G) families, which constituted 95.2Q of the total catch.

Slat-trap studies resulted in the collection of more fish in 19S9 than during any previous year

. (272 fish). Channel catfish (94.9%) was the dominant species collected. Flathead cattish (5.1G) was the only other species captured by stat-trap in 19S9.

1 l Lnuier, Mntusk3 & skelly Engineers i

i Disease symptoms, dek rmitics, and abnormalities were observed on 4S fish (0.7% of the total catch), representing ihree species. Parasites, fungus, and open sores were the most prevalent disorders. Blackspot, which infected a large number of fish in 1985 and 1986, was

. conspicuously absent in 19S7,19SS, and 1985' I

Of the 339 channel catfish collected during the 1989 study, eight individuals exhibited external symptoms suggestive of acromonalinfection (2A%). However, none of these fish exhibited internal symptoms of Acromonos. In addition, plated k; 7 smears from these fish did not result in any defi. nite growth patterns indicative of a motile aerornonad septicemia.

CHAPTER 1 INTRODUCTION The Illinois Department of Conservation (IDOC) reported mortalities in the early 1970s cmong channel catfish (Ictaluraspunctatus), and, to a lesser extent, black bullhead (I. melas),

stonecat (Noturus flavus), and gizzard shad (Dorosoma cepedianum) in the Rock River.

IDOC biologists attributed these mortalities to epizootic oct.urrence ofAcromonas hydrophila.

In 1976, IDOC biologists expressed concern that an increased incidence of Aeromonas may be associated with the elevation of river temperature resulting from discharge of cooling.

tower blowdown into the river from the Commonwealth Edison Byron Power Plant.

Commonwealth Edison Company (CECO) has recently completed a five-year monitoring program (19S3-19SS) to evaluate the fish community near the Byron Station blowdown in the Rock River. This report represents a continuation of the CECO program and presents results of the 19S9 monitoring program conducted by Lawler, Matusky & Skelly Engineers (uMS).

The program is intended to meet the following objectives:

Document the occurrence of Acromonas hydrophila in channel catfish in the vicinity of the Byron Station Continue to document the fish community in the Rock River near the Byron Station Also included in this report are comparisons of the 1989 electrofishing and slat-trap catch per-effort (CPE) with those obtained in previous years of study.

CHAPTER 2 MLTilODS i

2.1 FIELD PROCEDUhES 2.1.1 Sampling Locations Fish samples were collected at three river transect locations in the Rock River (R2, R3, and R4) and four stream locations (S3, S4, SS, and S6) (Figure 21 and Table 2-1). The river f transects represent sampling locations upstream from the cooling-tower blowdown discharge (R2), within the area of the discharge plume (R3), and 1.25 miles downstream from the discharge point (R4). Each river transect loca~:an was further divided into an cast (L) and west (R) bank. Each of the 10 locations was sampled weekly utilizing slat traps and electrofishing gear during the first four weeks in August.

The four stream samples were collected from the mouths of Woodland Creek (S3) and the

. Leaf River (S4), both upstream from the blowdown area; and Spring Creek (SS) and Silver Creek (S6), both downstream from the blowdown area. The river and stream locations are identical to those established during the seven years of preoperational aquatic monitoring from 1973-1979. Each location was identified either by a fix 1 easily recognizable landmatic (e.g., transmission lines, discharge canal, etc.), or marked with a fluorescent orange Dag.

2.1.2 Techniques and l'requency Electrofishing and stat-trap samples were collected at the designated locations once per week.

Electrofishing was conducted with a boat-mounted boomshocker utilizing a 3000-watt,230-volt,8.8-amp,3-phase Model 3MMV55 Kohler generator as the power source. Sampling was conducted along the shoreline on each side of the river at Locations R2, R3, and R4 and at

. the stream mouths of Locations S3. S4. 55, and S6. The order in which locations were to be  !

sampled was determined prior to each of the weekly efforts. Each location was sampled in J'l 2

an upstream direction for 30 min. If the end of a iocation was reached before 30 min had elapsed, the boat returned to the beginning of the sampling area and a second pass was ,

initiated slightly farther off shore, continuing until the 30-min period had expired.

Electrofishing was initiated no earlier than one half hour after sunrise and finished no later than one half hour before stinset. The outpu* of the generator was checked before cach sampling effort in order to determine amperage and volts. Electrofishing samples were scheduled over a two-day period.

Two cylindrical wooden stat-traps (15 in. in diameter and 58 in. long) baited with pressed soybean meal were set at each of the 10 sample locations. The two traps were set in water depths of approximately 4 to 6 ft and were tied together by 1/4-in. nylon rope. The mouth of each trap faced downstream and was set for approximately 48 hrs at each location each week. Fish were removed from each trap after 24 hrs and the traps were reset for a second 24-hr collection. At the end of the second 24-hr period, fish were again removed completing the 4S-hr semple period.

Four physiochemical parameters (temperature, dissolved oxygen, conductivity, and pH) were .

measured in conjunction with the fish sampling program. These data were collected at each slat trap location on the first and last day of each sampling period. Temperature (*C) and conductivity (smhos) were measured using a YSI Model 33 SCT meter. The YSI thermistor was calibrated for temperature using an ASTM certified thermometer. The conductivity mete; was checked using reference solutions of 74,147,1413. and 2767 pmhos at ambient temperatures prior to each sampling period. Dissolved oxygen (DO) (ppm) measurements were taken with a YSI Model 57 oxygen meter. The meter was air calibrated prior to each sampling date. A Cole-Parmer pH tester was used to determine Ph. The pH tester was calibrated against three separate pH reference solutions of 4.0,6.86, and 10.4 before each sampling period. DO and temperature were measured at the surface and near the bottom, whereas conductivity and pH were measured only at the surface.

I 2.2 SAMPLE PitOCESSING Fish were analyzed according to LMS' Fisheries Quality Control and Procedures Manual. All fish were identified to the lowest positive taxonomic level and enumerated. For each gear i

type, up to 25 individuals of a species were measured for total length (mm) and weight (g) at each location. Any remaining individuals of that species were counted and weighed en masse. Minnows (excluding carp) were counted and batch weighed only, Specimens that could not be identified in the field were preserved in 10% formalin and returned to the laboratory for positive identification. As a quality control procedure,10c7c of all electrofishirg samples were reexamined by a second analyzer. A voucher collection of all fish species identified during this monitonng program was compiled and is maintained at the Quad Cities Station.

I All fish were examined for external lesions or necrosis, evidence of parasitic infection, and emaciation. In addition, channel catfish from each location were examined for evidence of bacterial infection in the body cavity. As an aid in the identification of bacterial infection, a checklist of external and internal symptoms associated with bacterial diseases, particularly

. hemorrhagic septicemia, was used in the field diagnosis. The checklist was developed from Snieszko and Bullock (196S), Rogers (1971), Snieszko and Axelrod (1971), Warren (1974),

Meyer (1975), Canadian Department of Fisheries and En ironment (1976), and Piper et al.

(1982).

When external evidence of a bacterial infection was suspected, the channel catfish exhibiting such symptoms was placed into a labeled plastic bag and stored in a cooler containirig ice until it could be processed. Fi:,h were processed by first rinsing the infected fish's entire body with 95c~c denatured ethanol. A transverse incision was then made posterior to the dorsal fin of the fish with a sterile scalpel, and the backbone was then broken to expose the kidneys. An inoculatmg loop was used to prepare kidney smears on trypticase agar plates. The culture plates were labeled, packaged, and sent, with a blank, to Mr. Larry Durham, microbiologist, IDOC, for diagnostic testing.

2.3 EXPANDED SAMPLING -

In the event that more than 10To of the channel catfish catch in any given week exhibited external evidence of Aero,nonas (aeromonal) infection, sampling was to be expanded to the -

areas below the Rockford and Oregon Dams for the specific purpose of collecting additional channel catfish for evidence of aeromonal epizootic occurrences. Expanded sampling efTorts were not required in 1989.

I l GIAPTER 3 RESULTS AND DISCUSSION Electrofishing and stat trapping efforts near the Byron Station in 1989 resulted in the co!!cetion of 7291 fish from the Rock River, representing 41 species (Table 31). All 41 species were present in the electrofishing collections. Slat-trapping efforts resulted in the collection of only two species. No threatent.J or endangered species were collected (IDOC 19S2: Federal Register 1982). Twelve species collected prior to 19S9 were not collected in the present study; however, all of these species were uncommon in ll:e previous studies. A single American eel (Anguilla rostmin) was captured by electrofishing efforts for the first time -

in 19S9. Electrofishing catches are summarized in Appendix A by location (Tables A-1 through A 17) and by weight and length (Tables A-18 through A-21). Individual weight and length data from 1989 are presented in Appendix B.

3.1 ELECTROFISIIING

' I

. The 19S9 electrofishing catch at all locations near the Byron Station was dominated by cyprinids (42.29h) and catestomids (40.392). Young-of-year carpsucker spp. (15. Orc), bullhead minnow (13.07c). spottail shiner (12.4Fc), shorthead redhorse (10.07c), golden redhorse (9.19c), spotfin shiner (6.7?h'), and smallmouth bass (5.47c) were the only species that individually composed greater than 59h of the catch (Table 3 2). Bullhead minnow was the most abundant species collected at Locations R2 R3, and S6; spottail shiner was the dominant species captured at Locations R4 and S5; and golden redhorse was the most l abundant species collected at Locations S3 and S4 (Appendix Tables A-11 through A 17).

As a point of interest. it should be noted that large number., of young-of-year smallmouth bass were collected from the study area m 19SS. Large numbers of young-of-year and yearling smallmouth bass were once again captured in 19S9. It is believed that the low river flows that occurred in 19S8 and 19S9 were partially responsible for the strong recruitment of smallmouth bass during this period (Appendix Table A-22). Smallmouth bass over 10 im in

l I length were rarely noted during sample collections in 1988 or 1989. Similar results were reported by the IDOC (Sallec, pers, commun.), it remains to be seen to what degree,if any, the recent strong recruitment of smr'.lmouth bass may have upon the sport fishery of the Rock River.

The mean electrofishing CPE for alllocations combined in 1989 was 351.0 fish /hr (Table 3 3).

Electrofishing catches in 1988 (406.5 fish.hr) and 1989 were substantially higher than all ,

previous years. CPEs prior to 1988 had ranged from 18.S Sh/hr in 1976 to 145.3 fish /hr in 1977 (R = 73.9 fish /hr). Catch rates in 19SS and 1989 were much higher at each of the 10 sampling locations than had been recorded during any previous year. CPEs in 1989 ranged from 228.0 fish /hr at Location S3 to 464.5 fish!ht at Location S4.

The elevated electrofishing catch rates in 19SS and 1989 may partially reflect the effects of l

low river flows that concentrate fish and make them more susceptible to the sampling gear (Appendix Table A-22). In addition, low stable flows generally are considered conducive to strong recruitment of young-of year fish. Large numbers of small (Age 0+) redhorse, carpsucker, and other species were noted in the catch during 19SS and 1989 (Tabic 3-4). Low

- flows may have forced fish out of feeder creeks and into the Rock River doe to loss of haUtat. Discharge from Woodland and Spring Creek was reduced to a trickle during the majority of the 19S9 August sampling period.

I Mean catch rates and species diversity were similar between river (356.2 fish /ht) and stream mouth locations (343.1 fishhr) (Table 3 5). Slightly higher catch rates were obtained at I

upstream locations (364.9 fish /hr) than downstream locations (311.4 fishAir). Catch rates were also slightly higher along s e rirht (west) bank (3S2.2 fish /hr) than they were along the left (east cr plant side) bank (319 7 fish /hr). The variability in CPEs between the east (L) ar..I west (R) river banks can be mtributed to tte tour stream mouth locations (S3 S4 SS, and S6). Mean CPE for Stations S4 and S6 (right bank) was 439 fish /hr compared to 247 fish /hr for Stations S3 and S5 (!cft tank). Similar results were noted in 19SS (LMS 19S9).

The relatively high number of total species, the occurrence of species shifts, and the co!!cction g,

of new species noted from 1984 to 1988 when compared to earlier studies continued in 1989.

l The relative abundance of pollution tolerant species (carp and carpsucker spp., Bertrand et al.1984) was noticeably lower in 1989 (217c of the total catch) than it was when these studies began in 1979 (497c of the total catch). The recent increase in the appearance of species indicative of relatively good water quality (e.g., smallmouth bass, silver redhorse, white sucher, and other species), the increased number of species collected during recent years, and the decline in relative abundance of pollution tolerant species suggest that the water quality of the Rock River has improved since the 1975 through 1979 studies.

3.2 SIAT TRAPPING Slat trapping efferts resulted in the collection of 272 fish of two species during August 1989 (Table 3 6). Similar numbers of fish were captured during each of the four sampling periods with 61,6S,81, and 62 fish being captured during Weeks 1 through 4, respectively. The dominant fish collected in 1989 was channel catfish, which comprised 94.97c of the catch.

The remaining 5.1'~c of the catch was composed of flathead catfish. The total stat-trap catch

. ranged from five fish collected at Imcation R4R to 56 lish at Location R4L (Table 3 7).

Since 1985,771 fish, representing seven species and four families, have been collected by slat-traps (Table 3-S). Channel and Cathead catfish are the only species that have been captured by this method during all years of sampling. The 272 fish collected in 1989 represents the greatest number of fish, but the lowest number of species collected by stat traps smcc the inecption of the program. Channel catfish have dominated the catch during each of the five years of sampling, comprising 89.0% of all fish collected. Flathead catfish (6.77c) is the only

[

, other species that has contributed more than 57c to the total catch.

l 3.3 PllYSIOCilEMICAL DATA The physiochem' cal data collected during Ai!;ust 1989 and earlier years are summarized in Table 3 9 and Appendix Table A 23. Complete water quality data by date and location appear in Appendix Table A 24. During the sampling period, water temperatures rang:d from 19.9'C to 33.0T, DO from 3.0 to 15.1 mg1, conductivity from $$0 to 1200 pmhos/cm, and pil from S.0 to 9.2.

The minimum mean temperature was recorded at Ircation S5 (Spring Creek) and the maximum mean temperature was recorded at 1.ncation R2R (Table 3 9). Temperature was generally homogeneous from top to bottom indicating a well mixed water column. Warmest l

river temperatures were noted on 4 and 23 August when temperatures generally exceeded 30*C (Appendh Table A 24). Mean river temperat res for the August sampling period were l

slightly lower along the east or plant side bank I the river than they were along the west bank.

l DO concentrations were quite variable between each of the 10 sampling locatisms in 1989 (Table 3 9 and Appendix Table A 24). These concentrations were oftentimes gr:ater at the surface and along the west river bank than they were near the bottom or the cas' cank (plant g

side). Changes in DO concentrations were influenced by weather pattern *, that affected photosynthetic activity. IIcavy algal blooms were observed near the surfs.c during periods in which high DO readings were recorded. Depressed DO readings that were noted during i early morning hours near the bottom of the water column were assumed to be the result of respiration. The Byron Station Discharge Canal appeared to have little affect upon DO in s the Rock River during August 19S9.

liigher conductivity levels were noted along the east bank and below the Byron Station Discharge than at the remaining locations (Table 3-9). In addition, pli values along the cast (plant side) bank of the river were slightly less than values obtained from the opposite shore.

The higher pli values noted along the west bank of the Rock River may be related to the J

3.4 FISil DISOltDEllS l

Disease symptoms, deformities. and abnormalities were observed on 48 fish (0.7% of the total catch), representing three species (channel catfish, carp, and smallmouth buffalo). Five of these fish exhibited two or more abnormalities (Table 310). Paradies (fish lice, anchor worm, and leeches), fungus, exophthalmus (popeye), and open sores or abrasions were the most prevalent disorders. Parasites were present on 36 channel catfish 00.6% of the total channel catfish catch) in 1989. Leeches were the dominant parasite associated with channel catfish. Blackspot, which infected a large number of fish in 1985 ann 19S6 (EA 1986,1987),

has been absent in 19S7,1988, and 1989.

I Of the 339 channel catfish collected during the monitoring program, cipht individuals exhibited external symptoms that could be indicative of an aeromonalinfection (Table 311).

g I The weekly percentages of channel catfish exhibiting external symptoms ranged from 1.1 to 3.8G. The total percentage of channel catfish that exhibited possible evidence of aeromonal infection was 2,4%.

Kidney smears from the cipht channel catfi:,h that exhibited external symptoms of possible aeromonal infection were streaked on commercially prepared petti plates for bacterial analysis and shipped along with control blanks to Mr. Larry Durham, microbiologist, IDOC. None of the eight plates exhibited definite growth patterns indicative of a motile aeromonad J

septicemia (Table 312). llowever, one fish with exophthalmus (popeye) was infected with a related bacterium belonging to the genus litaio. This bacterium was not identified to species. librio is in the same family (Vibrionaceae) as Acromonas hydrophila, and both are regarded as secondary infectious agents that overcame the iinmune systems in fish that have been stressed. Although the two genera are sirnilar, this was not a true Acromonas infection.

This infected fish was collected from 1.ccation R2L, which is located upstream from the l Byron Station discharge. A. hydrophila was not detected on any of the plates streaked and examined during the 19S9 Rock River study.

1. Electrofishing resulted in the capture of 7019 fish representing 41 species. YOY carpsucker spp. (15. Orc), bullhead minnow (13. Orc), spottail shiner (12.4%).

shorthead redhorse (10.091), golden redhorse (9.1%). snotfin shiner (6.79c'), and I smallmouth bass (5.4rc) were the only species that individually composed more than 59c' of the total catch.

2. Cyrinids (42.29c). catostomids (40.39c'), and centrarchids (12.7%) dominated the electrofishing catch in 1989.

3. A single American cel (Ancuilla rostrata) represented the only new species collected l by electrofishing or slat trap efforts in 1909.

4. Electrofishmg CPEs in 19SS (406.5 fish /hr) and 1989 (351.0 fish /hr) were l substantially higher than any previous year. CPEs prior to 19SS had ranged from 18.8 fish!hr to 145.3 fish /hr (R = 73.9 fish /hr).

5. A total of 272 fish was collected in slat-traps during 1989. Channel catfish dominated the catch by comprising 94.97c of all fish sampled. Flathead catfish composed the remaining 5.19.

6. Eight of 339 (2.4rc) channel catfish examined exhibited external symptoms ruggestive of Acromonas infection. Ilowever, bacteriological examan'ien of these individuals I revealed that none of the eight individuals was infected by Acromanas.

7. The pe;centage of channel catfish infected with Acmmonas (09) in 1989 was I comparable to the percentages observed in 1989 (0%),1987 (2%).1986 (TG). and 19S5 (Src). Because of the low percentage of infected channel catfish, this reach of Ue Rock River appears to have low mortalities resuhing from aeromonad septicemia.
