A simple energy budget equation is developed to yield a bioenergetics model designed to simulate fish growth. Parameters for the model are estimated from the literature for application to yellow perch (Perca flavescens) and walleye (Stizostedion vitreum vitreum). Simulations are presented that demonstrate model output as functions of body size, activity level, ration level, food quality, and environmental temperature. Sensitivity analyses identify the importance of food consumption, activity, and excretion as biological processes represented in the parameters. On the basis of temperature conditions in selected lakes and specified feeding levels, simulations are presented to quantify the importance of year-to-year variation of temperature in determining growth. In heterothermal systems, temperature selection by percids can have a significant effect on growth. For walleye on fixed rations, annual growth can vary from zero to twofold increments due entirely to differences in summer temperatures. Variations in food quality have lesser effects.

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.

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.

And Function

A review of the literature indicated contrasts in retinal structure and function between perches (Perca spp.) and pikeperches (Stizostedion spp.). Foremost among these were differences in size and distribution of rods, size and shape of cones, extent of retinomotor responses, possession or lack of reflecting material, and relative concentrations of melanin. The perches are primarily active by daylight, whereas the pikeperches are most active during twilight or at night. The coincidental occupancy of shoal areas by yellow perch (Perca flavescens) and walleye (Stizostedion vitreum vitreum) at twilight is related to decreasing visual acuity of the former and the approach of optimum visual performance in the latter species. On this basis the two species have a classic predator–prey relationship.

In Vitro Effects

The in vitro effects of various gonadotropin and pituitary preparations on germinal vesicle breakdown (GVBD) were investigated in yellow perch (Perca flavescens) and walleye (Stizostedion vitreum). All preparations tested were effective in walleye; however, none of the preparations induced significant GVBD in yellow perch.

Oneida Lake

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.
