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
