MILWAUKEE, Aug. 12 (UPI) -- Invasive Asian Carp have been found in the Wisconsin River in their seeming inexorable migration north despite attempts to halt them, officials said.
The Wisconsin Department of Natural Resources said a bighead carp was caught in the Lower Wisconsin River near Lone Rock while "environmental" DNA sampling on the St. Croix River in the northwestern of the state has turned up positive samples of silver carp, the Milwaukee Journal Sentinel reported Thursday.
