DOOR COUNTY, WI (AP)-- The Wisconsin Department of Natural Resources says Asian carp DNA has turned up in Wisconsin's Lake Michigan waters for the first time.
The single positive water sample for the jumping silver carp was taken May 31 in Sturgeon Bay near Door County's Potawatomi State Park.
The sampling was part of a Lake Michigan-wide survey looking for evidence of Eurasian ruffe, a different type of invasive fish species.
The water sample was not screened for the presence of Asian carp DNA until this fall. DNR fishery director Mike Staggs says the agency did not get word of the positive result until last week.
The Milwaukee Journal Sentinel reports DNR officials plan to go back to the Sturgeon Bay area to do more sampling next week.
