Change In Mean

The sequence of events that led to a decline in numbers of American eel (Anguilla rostrata) and esocids and an increase in numbers of walleye (Stizostedion vitreum vitreum) in Oneida Lake from 1900–74 are reviewed. Demise of eel and esocids was followed by a rise in numbers of walleye, but little change in mean size of individual walleye. Reduced interspecific competition apparently enhanced walleye recruitment, but the anticipated increase in growth of walleye was probably inhibited by intensified intraspecific competition. This interpretation was supported by evidence that recruitment and growth of walleye in 1957–74 were regulated by prey abundance. Transition from a diverse predator population to one dominated by walleye was orderly and yellow perch (Perca flavescens) remained the most abundant prey.

Model Predictions

Zebra mussels (Dreissena polymorpha) recently invaded North American aquatic ecosystems and are hypothesized to impact lakes by increasing water clarity through filtration and shunting energy from pelagic to benthic pathways (ES effect). We used an individual-based model of Oneida Lake, New York, walleye (Stizostedion vitreum) and yellow perch (Perca flavescens) populations to simulate ES effects on percids by lowering zooplankton density and production rates and increasing benthos rates. We performed 50-year simulations involving both zooplankton and benthos changes together and each change alone. We also performed simulations to determine robustness of model predictions under different assumed levels of zooplankton and benthos, increased forage fish and mayflies, and walleye stocking. Predicted ES effects were elimination of walleye high-recruitment years, resulting in a 30% reduction in adult walleye abundance. Yellow perch adult abundance increased by 6% due to reduced walleye predation. Neither component (zooplankton or benthos) of ES generated the same total response for yellow perch as both components together. Simulated walleye stocking and increased forage fish density had little effect on model predictions. Increased mayfly densities offset predicted ES effects by buffering predation on juvenile percids. Model predictions of ES impacts on percids generally were consistent with observed changes in Oneida Lake since zebra mussel arrived.

Alternate Prey

Abundance of eight successive year-classes of walleyes (Stizostedion vitreum vitreum) was measured at intervals from hatching into the second year. Each year-class arose from an initial stock of 12–18 billion eggs. Population of pelagic larvae was augmented in some years by the release of hatchery-reared larvae but the effect on year-class size was obscured by mortality after young became demersal. Decrease in number of fingerlings was attributed to predation by older walleyes. Intensity of predation was influenced by abundance of alternate prey and duration of cannibalism by growth of young walleyes. Five year-classes that were monitored through age 4 contributed 12,000–478,000 walleyes to the adult stock.

Adult Growth

We used long-term data on Oneida Lake, New York, to evaluate hypotheses about the effects of introduced zebra mussels (Dreissena polymorpha) on yellow perch (Perca flavescens). We detected no change in survival, diet, or numbers of young-of-the-year (YOY) yellow perch. YOY growth increased in association with zebra mussel introduction and was marginally correlated with zooplankton size, which increased after zebra mussel introduction. Low numbers of YOY in recent years did not explain their increased growth rate. The percentage of age 3 and older yellow perch that consumed zooplankton and benthos increased after zebra mussel introduction. Water clarity, which has increased since zebra mussel introduction, was inversely related to the percentage of the adult population with empty stomachs and positively related to the percentage that consumed benthos. The percentage of adult yellow perch that consumed zooplankton was positively related to zooplankton size. Despite the increase in percentage of adults consuming both types of invertebrate prey, we detected no changes in adult growth associated with zebra mussel introduction. This suggests that the principal effects of zebra mussels on yellow perch in Oneida Lake were not via benthic pathways but through modifications of water clarity and zooplankton. Thus far, these effects have not been negative for the yellow perch population.

We examined an 11-yr (1975–86) field data set to determine whether annual differences in age-0 yellow perch (Perca flavescens) growth in weight were related to the abundance, size structure, and species composition of zooplankton in Oneida Lake, New York. A model for prediction of age-0 yellow perch weight was determined using a multiple regression technique; age-0 yellow perch wet weight (grams) was the dependent variable while age-0 yellow perch density, water temperature, calendar day, and cumulative biomass of both zooplankton taxonomic groups (daphnids, "other cladocerans," calanoids, cyclopoids, and nauplii) and zooplankton size classes (< 1.1 mm, 1.1–1.7 mm, and > 1.7 mm) were the independent variables. Analyses were based on an integrated approach where time was measured in cumulative temperature units and yellow perch weight was considered a function of the cumulative amount of food available. Below a cumulative temperature of 1350 °C∙d−1, none of the independent variables were related significantly (P < 0.05) to yellow perch weight. Beyond 1350 °C∙d−1 age-0 yellow perch weight was strongly correlated with the biomass of Daphnia and significant (P < 0.05) prey size variables shifted toward larger prey as fish grew. Our results indicate size- and species-based interactions between fish and zooplankton play an important role in regulating growth of age-0 fish.

Sustained swimming ability of limnetic larvae of walleye and yellow perch from Oneida Lake, New York, was compared in an experimental apparatus. The current velocity that 50% of the larvae could sustain in 1-hr tests was recorded for each 1-mm length class. Yellow perch larvae swam better than walleye larvae for length classes less than 9–10 mm total length (TL), but swimming ability of the two species was equal for length classes from 9 to 15 mm. Velocities that larvae under 9.5 mm TL could sustain were less than 3.0 cm/sec, and it was concluded that newly hatched young of both species would be subject to transport by lake currents of greater velocity. Relative swimming ability, expressed as the number of body lengths/sec that a larva could sustain for 1 hr, approached an asymptote between 3 and 4 lengths/sec for larvae longer than 9.5 mm. The greater swimming ability of newly hatched yellow perch larvae, compared with that of walleyes, appeared to be related to the smaller yolk sac of yellow perch at hatching.
