    modeling and population estimates for this eastern population are ongoing, but it is clear that the eastern population is small relative to the western population (Ryan et al. ). Incorporating the effects of migrating adult walleye remains challenging. The eastern Lake Erie walleye population is briefly described in the WMP. on the walleye stocks that spawn on shoals and in tributaries of the western basin and generally inhabit the west and central basins of Lake Erie. This is the primary population of interest to LEC walleye management as it provides most of the benefits to users throughout Lake Erie. Additional stocks within the lake are found in Presque Isle.

    With quota management, the walleye stock in western Lake Erie responded well to limited exploitation, steadily increased, and expanded its range. As population expanded, growth began to decline and was more apparent in the young-of-the-year (YOY) in the s, and in older walleye .   Last year, the walleye hatch in Lake Erie’s Western Basin produced the largest number of new walleyes ever recorded. New reports show the .

    The model was fitted to the walleye population of the western basin of Lake Erie where well documented changes in abundance have produced changes in growth rates, condition factor, and age at maturity (Knight et al., , Muth and Wolfert, ). Huge harvests of walleye slumped after record gill net catches, and the popular Lake Erie blue pike, a cousin of the walleye, became extinct in Lake Erie. Long-time director of Ohio Sea Grant, Dr. Jeff Reutter, enjoys an afternoon of Lake Erie walleye fishing .

Bioenergetics modeling can also be applied to a percid population to estimate the amount of food being annually consumed by the percid population.

For each year, we used individual-based bioenergetics modeling to compare growth and consumption by walleye in Lake Erie's western or central basin with those of walleye moving seasonally between basins.

Population structure strongly affected walleye growth and consumption but had little influence on interbasin growth rate comparisons. A multi-agency task group has been created by state agencies surrounding Lake Erie to monitor and protect the Lake Erie walleye population.
