WALLEYE
Walleye lives in deep large streams, lakes and reservoirs over firm sand, gravel, or rocks and can be found in the entire drainage system of Hudson's Bay and the Great Lakes Basin. It is the largest North American species in the perch family and one of the most sought-after sport and food fish. Walleye feeds on aquatic insects, crustaceans, amphibians, and almost any available species of fish. In Canada it has acquired the nickname "Pickerel".
