Walleye – Great Lakes
Walleye is a freshwater species of fish found throughout the northern part of North America.
In the Great Lakes, Walleye have been the target of recreational and commercial fisheries for hundreds of years, and today most Walleye are commercially caught from the Canadian side of Lake Erie.
Walleye grow quickly and reach sexual maturity at a young age, but habitat degradation and high fishing pressure have decreased their abundances over time.
Walleye have a medium abundance overall across the Great Lakes, but population sizes varies between and within lakes.
Walleye are typically caught using gillnets, which have a low to medium impact on bottom habitat.
This fish may have high levels of mercury and PCBs that could pose a health risk to adults and children. More mercury and contaminant info here.
