Brown trout, Chinook and coho salmon are all currently stocked in one or more of the Great Lakes, however none of these prized catches are native to the basin. These fish were stocked to help manage invasive species and to build a sport fishery.
Over the course of the year, the Department of Natural Resources will stock nearly 19 million fish, including native and non-native species. Todd Grischke, Lake Huron basin coordinator for the Michigan DNR, discusses how fish populations in the Great Lakes have evolved and how they are maintained.
