J 3.1.2.a.3 Fisheries Population Studies Proceduras Fish populations at Locust Point were sampled by 3 methods, gill ne'ts, shore seines, and trawls, from May through November 1978 (Table 1).
Samples could not be collected during April due to an unusually long winter and the presence of ice.
All fish captured were weighed, measured, and identified to species (Trautman,1957; Bailey et al.,1970). All results were keypunched and stored on magnetic tape at The Ohio State University Computer Center. Results were reported as catch per unit effort (CPE).
Gill Nets. Experimental gill nets were set parallel to the intake pipeline at Stations 8 and'26 and parallel to the discharge pipeline at Stations 3 and 13 (Figure 1).
Stations 3 and 26, control stations, were positioned 3000 feet northwest of Station 13 (plume area) and 8 (intake), respectively.
Each gill net measuring 125 ft x 6 ft and consisting of five 25-ft contiguous panels of 1/2, 3/4, 1, 1-1/2, and 2 inch bar mesh, was fished for approximately 24 continuous hours monthly (Table 1). One unit of effort consisted of one 24-hr set with one of these gill nets.
Shore Seines. Shore seining was conducted monthly (Table 1) with a 100-ft bag seine (1/4 inch or 6 m bar mesh) at Stations 23, 24, and 25 (Figure 1). The seinewasstretchedperpendiculartotheshorelineuntiltheshorgbrailwasat the water's edge.
The far brail was then dragged through a 90 arc back to shore. Two hauls were made at each station in opposite directions. One unit of effort consisted of the two above described hauls.
Trawls. Four 5-minute bottom tows with a 16-ft trawl (1/8 inch mesh bag) were conducted monthly (Table 1) on a transect between Statio'is 8 (intake) and 13 (thermal plume area) at a speed of 3-4 knots.
For comparative purposes similar tows were conducted on a transect between Stations 3 and 26. One unit of effort consisted of four 5-minute tows.
Results Of the 48 fish species reported from the Locust Point vicinity Since 1963, 24 were captured during 1978, in addition to one newly recorded species, the goldenshiner, Notemigonus crysoleucas (Table 2).
The three fishing methods combined yielded a total of 19,021 fish, of which 24.4% occurred in gill nets, 6.3% in trawls' and 69.3% in shore seines (Table 3).
The combined results of all three methods of capture indicated that the dominant species in the Locust Point vicinity during 1978 in order of abundance were:
gizzard shad (67.0%),
spottail shiner (6.9%), emerald shiner (6.7%), alewife (5.9%), yellow perch (5.4%), white bass (3.9%), and freshwater drum (2.3%) (Table 4).
No other 4
species constituted more than 1.0% of the catch by nunter.
Gill Nets.
Gill nets set from May through November yielded 4,636 fish weighing 286.2 kg and representing 20 species (Table 5). Monthly catches of all stations combined ranged from 310 (CPE = 77.5) in November to 1,516 (CPE = 379.0) in September. Maximum catch occurred at Station 26 in September

(637 fish), and minimum catch occurred at Station 8 in May (20 fish).
Species captured were both adult fish and young-of-the-year, with yellow perch, spottail shiner, freshwater drum, gizzard shad, and wnite bass predcminating.
Shore Seines. Shore seining during 1978 yielded 13,177 fish weighing 28.9 kg an Frepresen'tTng 13 species (Table 6). Monthly catches of all three stations comoineo ranged from 44 in October (CPE = 14.7) to 5,869 in June (CPE = 1,956.3). The large June catch consisted primarily of your.g-of-the-year gizzard shad (mean length = 37.8 mm).
Species captured shore seining were primarily young-of-the-year, with gizzard shad, alewife, emerald shiner, spottail shiner,,,d white bass predominating.
Trawls.
Trawling in the Locust Point vicinity during 1978 yielded 1,208 fish WiFing 40.5 kg and representing 20 species (Table 7).
Monthly catches from both transects combined ranged from 41 (CPE = 20.5) in May to 340 (CPE = 170.0) in August. Maximum catch occurred at Transect 8-13 in August (219 fish), and minimum catch occurred at Transect 8-13 in May (15 fish).
Gizzard shad, white bass, and spottail shiner were the dominant species. Rainbow smelt, occasionally taken in larger numbers, were primarily young-of-the-year.
.hltsis The Lake Erie fish comunity at Locust Point in grevious years has beer dominated by gizzard shad, alewife, spottail shiner, yellow perch, white bass, emerald shiner, and freshwater drum.
Percentages of these species varied from year to year, but the same species dominated.
During 1978, fish sampling at Locust Point yielded similar results. Large numbers of all the dominant species were young-of-the-year taken close to shore by seining, but adults of these species were also numerically more abundant than other species captured during 1978.
The open, wave-swept nature of the nearshore zone at Locust Point precludes the establishment of large populations of species which require more sheltered, quiescent conditions (i.e.
carp, bullheads, smallmouth bass),
altnougn small populations or transient individuals of such species do occur in the area. The less abundant species captured during 1978 were generally of this type.
Pelagic and benthipelagic schooling species consisting of intirmediate predators (i.e., white bass, freshwater drum, and yellow perch) and forage fish 4
(i.e. alewife, gizzard shad, spottail shiner, and emerald shiner) make up the bulk of the community, with terminal predators (i.e., walleye, sauger, and l
channel catfish) being comon but less abundant.
The total number of fish captured at Locust Point during 1978 was greater than in 1977, but less than in 1973 (Reutter and Herdendorf,1977). Variability in catch from year to year at Locust Point is a function of both sample timing and actual density of fish in the vicinity.
The largest component of variability is found in shore seine catcn, which consists primarily of young-of-the-year.
Time of day, as well as season and actual population densities, can affect the abundance of young-of-the-year within range of shore seining on any sampling day. Results of this type are typical of schooling species, wnich are generally not uniformly distributed over a given area, and become more variaole as sampling frequency decreases.

In the past, analyses of gill netting results at individual stations indicated that fish densities were generally greatest closer to shore.
This pattern was not hignly evident during 1978 except during May and June (Figure
~
2).
Larger numbers of fish captured at all four stations during September consisted primarily of alewife and gizzard snad.
Abundance trends at control stations (3 and 26) were not markedly different from trends at test stations (8 and 13). Large numbers of fish captured during September at Station 25 may have been an artifact af commercial trapnetting in the area.
Station 26 is relatively isolated northwest of the main commercial netting field and may be more advantageously situated to intercept schools of fish, which are otherwise diverted or obstructed among the trap net mazes.
No trend of attraction to or repulsion from the plume area (Station 13) or the intake area (Station 8) was evident.
Trawling results indicated that fish populations in the vicinity of tne intake-discharge complex (Transect 8-13) exhibited abundance trends similar to those around the control transect (Transect 3-26) (Figure 3). Somewhat greater abundance of fish around transect 8-13 may be attributed to increased cover for fish around the rip-rap material in the vicinity, but gill net results (Figure
- 2) do not support this conjecture.
In conclusion, fish populations at Locust Point during 1978 were similar to those observed in the past.
No indication of adverse impact due to the Davis-Besse Nuclear Power Station was observed.
