COMMON NAMES: Walleye, Pickerel, Yellow pike, Wall-eyed pike

SCIENTIFIC NAME: Stizostedion vitreum vitreum

IDENTIFICATION: The walleye has a long slender body with a yellow-olive color with a brassy overcast on the sides. The tail fin has a white spot on the bottom edge. The eye is large and cloudy, and there is a dark blotch on the webbing between the last three spines of the first dorsal fin. The mouth is filled with sharp canine teeth. The walleye looks similar to the sauger and saugeye.

RANGE AND HABITAT: The walleye is native to Michigan but historically was only found in the Great Lakes. However, walleye have now been stocked into a number of larger reservoirs around the state. Walleye prefer clear to slightly turbid waters. They usually occur in greatest abundance over reefs, shoals of gravel, bedrock, and other firm bottoms.

LIFE HISTORY: Walleye spawn throughout the month of April when water temperatures are between 40 and 55° F. Walleye are free spawners that deposit their eggs in the riffle areas of tributary streams or over gravel to boulder-sized rocks in reef areas of Lake Erie. The eggs hatch in about 10 days. Females can lay as many as 400,000 eggs. Young walleye feed on zooplankton and insect larvae for most of the first year. Following this stage the young shift to a diet of small fish. Adults in lake Erie feed mainly on emerald shiners, gizzard shad, alewives and rainbow smelt. When these species are not available they will feed on almost any suitable sized prey. Adult walleye feed primarily during low-light intensity periods of the day (sunrise and dusk).

ADULT SIZE: Walleye average 2 to 4 pounds and are between 14 and 22 inches. The state record walleye weighed 15.95 pounds and measured 33 inches in length.
