Five species of salmon and trout support a world-class recreational fishery in Lake Michigan. Stocking has played an important role in maintaining the balance between predators and baitfish, such as the non-native alewife, since the late 1960s. If too many salmon and trout are in the lake, baitfish decline and salmon starve or fall prey to disease. If too few salmon and trout are in the lake, the non-native alewife could foul beaches and affect native species.
Ongoing research is being used to investigate the possibility that changes to stocking policy could improve fisheries and limit the risk of predator-prey imbalance. Fisheries managers in Michigan, Wisconsin, Illinois and Indiana will set a stocking policy for Lake Michigan salmon and trout by fall of 2012.
