UNDATED (WSAU-Wheeler News) For the first time, there's evidence of an Asian carp in the Wisconsin waters of Lake Michigan. A new study by Notre Dame and the Nature Conservancy turned up D-N-A for the bloated invasive carp at Sturgeon Bay, near Potawatomi State Park in Door County.
The D-N-A was found in a water sample taken at the end of May. It was not screened until this fall, when a comprehensive survey was conducted in search of a different type of invasive species. It was the only positive sample among 282 taken from the Wisconsin portion of Lake Michigan, as part of a larger invasive fish survey by Notre Dame researchers and government crews. About 50 of those samples came from the Sturgeon Bay area.
State natural resource officials plan to do more testing in the area next week -- and for now, at least, they say there's no reason to panic. The D-N-R's Bob Wakeman says his agency needs to clarify what the new discovery really means. Dozens of water samples in the Chicago area have turned up D-N-A for Asian carp, which gobble up the food that native fish in the Great Lakes rely on.
