Fish and fisheries

Great Lakes fisheries are under stress, and new management approaches must be found to cope with these difficult challenges. The list of needed research encompasses fish biology and population dynamics, habitat and ecosystem health, toxic chemical contaminants, the potential effects of climate change, socioeconomic impacts and conflict resolution. Recent Wisconsin Sea Grant-supported fisheries research has focused on the lake trout fishery and food web dynamics in Lake Superior, and the decline of yellow perch and smelt fisheries in Lake Michigan.
