The USFWS Alpena FWCO-Detroit River sub-station worked with partners from Ohio DNR, Michigan DNR, and Sea Grant to develop signage that will increase public awareness about the threat invasive Grass Carp pose to the Great Lakes. The sign is one of three different signs and interpretive panels that will be posted at boat ramps and other strategic places in Michigan and Ohio to inform the public about Grass Carp in the Great Lakes.
