Grass carp - type of Asian carp
BENTON HARBOR, Mich. (AP) -- The state plans to take steps to prevent illegal carp from entering Michigan waters after tests confirmed one in southwestern Michigan was capable of reproducing.
The Michigan Department of Natural Resources on Thursday announced that the results on the grass carp were "cause for concern."
Grass carp are considered a species of Asian carp although they don't pose the same risk to the ecosystem. According to the DNR, they eat important plants and can disrupt fish habitat.
The DNR says the 33-pound fish was found in June in the St. Joseph River in Berrien County.
The agency says grass carp already were known to be in the river. Potential entry points will be assessed. Electrofishing and monitoring also are planned to determine the spread of the fish.
