1987 FISH IMPINGEMENT STUDY REPORT I. Introduction An impingement study was conducted from January 7,1987 to January 6,1988 to determine both the total number and variety of fish impinged by our service water system. This information was used_ to 1) verify impingement predictions made in the PNPP rinal Environmental Statement (FES), and 2) determine the impact of the service water system on the fish populations,in Lake Erie. II. Methods Impinged fish were collected weekly. All impinged materials were washed from the traveling screens on a daily basis into a ('57 trash basket designed to allow water to escape while retaining fish and debris. Fish were _ lorted by species, counted, measured, and examined for physical conditions such as fungus, parasites, tumors,. and spawning condition. III.Results A total of 83,431 fish representing twenty-three species were collected (see Attachment 1). The greatest number of fish were collected in April (24,540); the fewest fish vere collected-in August (19). In general, impingement was highest between January; and April, then decreasing through f all (see Atta-ment

2). -The greatest variety' of species, sixteen, was collected on March 5. The majority of fish' collected were gizzard shad, which represented 39.5% of the total. Five individuals of one endangered species, the burbot, were-also collected.

IV. conclusions The -number of fish impinged at PNPP agrees with predictions-made_in the rES. Impingement at Perry reflects the current species composition.in the lake and has a low impact on fish populations. Important species were not impinged in quantities that were unusual or cause for concern. (See Discussion for details)- l k$dllj@jpg 880413 1437 C pyg

Ck o_' r i l V. Discussion The FES predictions were as follows: j 1)The species composition of impinged fish at Perry would be similar to that observed at the Ashtabula C plant. 2)The number of impinged fish at Perry probably will be lower (than that at Ashtabula C plant) as a result of lower water withdrawl volume and velocity.-capped intakes. The following table compares Ashtabula C results to those observed at Perry. species Composition (*) Powe?; Plant No. Fish Ashtabula C 222,000 95% Rough and Forage 51 Commercial and Sport Perry 83,431 60% Rough and Forage 40% Commercial and Sport (*I species classification is shown on Attachment 1 The species composition at Perry is different than that at Ashtabula because of changes in lake conditions that occurred during the time between the two studies. The Ashtabula study was conducted in 1977-78, ten years prior to the study at Perry. Lake-wide changes in species composition that occurred during those ten years are reflected in impingement. Changes include en increan< in the populations of commercial and sport species (such as whits perch, walleye, and yellow perch), and a decrease in populations of rough and forage species (such as rainbow smelt). The following are accounts of the predominant and importcht species impinged. A) Gizzard shad Gizzard shad was the most abundant species impinged (32,975). This species exhibits a high winte< mortality rate, is very abundant, and has a low market value. For these reasons, the impingement of gizzard shad at Perry is neither unusual nor cause for environmental (e concern. mm.

(L hb B) White perch The majority of white perch collected were probably naturally stressed by a psthogenic bacteria ) (Aeromonas) before being impingeo. Over 90% of the total 29,709 white perch were collected in May and April, when this bacteria becomes active as lake temperatures increase. The perch collected during those two months increasingly exhibited the symptoms of infection, which include subcutaneous bleeding at scale and fin bases. In addition, relatively few white perch wyyy collected compared to the sport harvest of 231,000 . For these reasons, their impingement at Perry is not a cause for concern. C) Rainbow smelt Natural stress associated with spawning causes high mortality in this species. However, this usually occurs in May after spawning rather than in December and January, as was observed in this study. Impingement of this species was probably caused by a combination of several factors, such as impaired swimming ability due to prespawing conditions, over-wintering stress, and cold lake temperatures. Other specits of interest include those that are important sport and/or cons ircial species. These are yellow perch, white (' bass, walleye, ch innel catfish, and northern smallmouth blackbass.Thetotalcatchofthesespecies,g},938, represents only.02% of the sport harvest of these fish and therefore is not cause for concern. The burbot was the only endangered species impinged during the study. The five fish collected reflect the repopulation of Lake Erie by this species, which increased in numbers suf ficiently to be removed f rom the endangered species list in 1988.

This informatici has been used to determine the impact of systes operation on the fish populations in the nearby vaters of Lake Erie ected weekly. All impinged materials vere vashed daily from Fish vere er the traveling screens into a trash basket designed to allov vater to escape while retaining fish and debris. Fish vere sorted by species, coutited, meartured and examined for physical conditions ruch as fungus, parasites, tumors and spavning condition. A total of 18,902 fish representing 21 species vere collected (Attachment the 1). The greatest number of fish vere collected in January (4648): C'; fevest fish vere collected August (8). In general, impingement was highest between Jar.uary and April, then decreasing through f all (Attachment 2). The majority of fish collected '.ere rainbov smelt which represented 49.8% of the total. No endangered species were collected. The number of fish collected in 1968 vas significantly lover than in 1987 (Attachment 3). ',everal reasons for this are possible 1.The vashing mechanism for the service water traveling screens was operated continuously from January through mid-March in ordar to prevent ice buildup. This resulted int o a significant amount of noise and turbulence. This magave been s sufficient to cause an avoidance reaction in some fish, o constant vater flov into the trash basket. This kept fish soving inside the basket, which resulted in 1) fish being ground against the botton and sides of the basket until reaching a size capable of flushing through the strainer holes, and 2) small fish being kept in contact with the strainer holes in the trash basket, providing more opportunities for them to be flushed through. o occasional overflow of the basket. This resulted in losing fish along with the water (17ving out over the top of the basket. 2.This year may have been a poor spawning year for giarard shad. Since k. this was the predominant species in 1987, their absence from the 1988 collections reduced total impingement by over 30,000 fish.

The two predominant species impinged vere rainbow smelt and white perch. Natural stress associated with spawning causes high mortality in rainbov smelt. However, this usually occurs in Hey rather than in December and January, as observed this year. Impingement was probably caused by over-vintering stress. The majority of white perch co11ceted appeared to be stressed by a pathogenic bacteria (Aeromonas). Over 80% of the total 5082 vhite perch vero collected during the tine period when this bacteria becomes active (as lake temperatures vara in spring). The perch collected during this time increasingly exhibited the symptoms of this infection, which includes subcutaneous bleeding at scale and fin bases. The number of ..*chcollectedthisyearwasongonefifththenumbercollected white in le er 2.21 of the sport harvest. Other specie? of interest include those that are important sport and/or cowercial species. These are white bass, f reshwater drum, yellow perch, valleye, northern rockbass, channel catfish. northern smallmoath blackbass and carp. The total number of these species, 2,249, represents less than.02% of the 1987 sport harvest. Tour burbot were collected this year. Although this species was reported as endangered in 1987, its population status was upgraded in 1988 when it was removed from the endangered species list. (. Overall, impingement at PNPP was very low. It was not suf ficient to-significantly impact fish populations in the nearby waters of Lake grie. s, Important species were not impinged in quantities that were unusual or cause tor concern. In addition, impingement at Perry is well within values predicted in the Final Environmental Statement. For these reasons, fish '.epinsement monitoring is being discontinued. Future fish kills or other unusual impingement events vill be addressed on a case by case basis. 3 (1) Anderson, J.
