Number of young perch (Perca flavescens) consumed by walleye (Stizostedion vitreum vitreum) in Oneida Lake was determined from analysis of feeding chronology and digestion rates. Young perch were ingested between sunset and sunrise and digestion rates were estimated from the decrease in weight of perch in stomachs during the day. Walleye prédation began in late June and by October the number of young consumed ranged from 17,940 to 242,900 ∙ha−1 in 1971–73. Concurrent studies indicated an additional 590 to 56,130 young were eaten by adult perch.Minimum population of young perch in June was calculated by adding to the number of young that survived to fall, the number consumed by walleye and adult perch. Populations reconstructed in this manner approximated independent estimates of the pelagic population in June. Mortality of young perch was apparently attributable to predation by percids and reconstructed populations accurately portrayed seasonal trends in abundance of young perch. Key words: predation, walleye, yellow perch, digestion, mortality

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.

Analysis of the 1960–76 creel survey data for Lake Nipissing and relevant data collected by the Lake Nipissing Fisheries Assessment Unit from 1969 to 1976 showed a generally declining walleye (Stizostedion vitreum vitreum) contribution to the Lake Nipissing fishery. Variable year-class strengths alone did not adequately account for the changes. Overexploitation of the resource was strongly suggested by decreased catches per unit of effort, recruitment of younger walleye (many of which probably never spawned) into the fishery at least after 1968, and increased growth rate. The population is probably affected as well by climatic factors, interactions with white suckers (Catostomus commersoni), northern pike (Esox lucius), and yellow perch (Perca flavescens), and by technology and watershed influences.

Fish Species Diversity

In a northeastern Minnesota lake subject only to sportfishing, removal of 85% of the estimated standing crop (34 kg/ha) of adult white suckers, Catostomus commersoni in 1966 was followed by marked changes in community structure and interrelations. During 7 yr alter the removal: catch indices for adult suckers remained far below those before the sucker removal but juvenile suckers increased about 17-fold; yellow perch, Perca flavescens, increased about 15-fold; walleye Stizostedion vitreum vitreum, standing crop increased about one-third; mayflies increased in diet of adult perch and smaller invertebrates decreased; micro-crustaceans increased in diet of young-of-the-year and juvenile perch; young-of-the-year perch increased in diet of adult walleye; walleye angling yield increased from an average of 3.0 kg/ha before the removal to an average of 4.9 kg/ha in 1970–73; the rate of exploitation of adult walleye did not change with increase in angling effort; and the increased walleye harvest consisted mostly of fish recruited to the catch during the fishing season. The average annual harvest of walleye in 1970–73 exceeded estimated potential production for all fish by 81.5% and probably cannot be sustained. Removal of white suckers from lakes with limited fish species diversity appears to benefit percid populations.

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.

Abstract Bioenergetic models for mercury accumulation in walleye (Stizostedion vitreum) and yellow perch (Perca flavescens) were calibrated on the basis of data which indicate that methylmercury concentrations in oxic, unpolluted lake waters are on the order of 0.04 to 0.40 ug m−3. This range reflects improved analytical capabilities in recent years and is significantly lower than earlier estimates on the order of 4 μg m−3. For both yellow perch and walleye, the calibrations of bioenergetics equations in this study strongly suggest that the food uptake pathway is dominant for methylmercury in oxic unpolluted freshwaters, in comparison to uptake across the gills. The food pathway is predicted to be responsible for 90% or more of methylmercury uptake in yellow perch and walleye in oxic freshwaters with methylmercury concentrations less than 0.3 to 0.4 μg m−3. As a result of the dominance of the food uptake pathway, mercury concentrations in fish were strongly influenced by the mercury concentration in the diet. A change in the source of the walleye diet from benthos to fish resulted in a significant increase in the rate of mercury accumulation. The calibrations resulted in a 5-year old yellow perch achieving a mercury concentration of 0.15–0.20 μg g−1, and a 4-year old, 1 kg walleye achieving a mercury concentration of about 0.45 μg g−1.

Fishes reared in captivity are predator-naïve and suffer large predation mortality when stocked into lakes with a full complement of predators. We tested the potential of predator training to enhance post-stocking survival of hatchery-reared walleye (Stizostedion vitreum). In the first part of the study, we found that walleye (i) use chemical cues for assessing predation risk, (ii) do not have innate recognition of the odor of northern pike (Esox lucius) as an indicator of predation, and (iii) associate predation risk with pike odor after a single simultaneous encounter with pike odor and chemical alarm cues from walleye skin. In the second part of the study, we attempted to mass-train yellow perch, Perca flavescens (as a surrogate for walleye), to fear pike odor. Perch response to pike odor was not changed by placing sponge blocks containing pike odor and perch alarm cues around the perimeter of a pond. On pre- and post-training assays, perch avoided traps scented with perch alarm cues, but did not avoid traps labeled with pike odor or water. We conclude that recognition training offers potential as a management tool for walleye, but significant logistic challenges must be solved before it can be implemented.
