Report Asian Carp

Bighead and silver carp are spreading to lakes, rivers and streams in the Mississippi River and Great Lakes region, but are not yet established in the Great Lakes. They are well-suited to the climate of the Great Lakes region, which is similar to that in their native region in Asia, and these carp particularly favor large rivers and connecting lakes. Biologist expect that Asian carp will disrupt the food chain that supports the native fish of the Great Lakes, such as walleye, yellow perch, and lake whitefish. Due to their large size and rapid rate of reproduction, bighead and silver carp pose a significant threat to the ecosystem of the Great Lakes Basin. Silver carp leap high out of the water when disturbed by watercraft. Boaters can be and have been injured by these leaping fish. Fear of injury could diminish the desire for recreational boating activities in areas inhabited by these fish. Both bighead and silver carp may result in diminished fishing opportunities resulting from population declines of the species of fish sought by recreational anglers and commercial operations. It is illegal to transport or possess live bighead, silver, grass, or black carp in Michigan.
