“These types of carp are highly invasive species that out-compete Wisconsin native fish species and can destroy their habitats,” said Lt. Robert Stroess, DNR warden administrator for Commercial Fishing, Wholesale Fish Dealing and Charter Fishing Enforcement. “The species is top on the Least Wanted Aquatic Invasive Species List from the Great Lakes – St. Lawrence Governors and Premiers.” The DNR says the fish farm operator is facing four criminal charges of possession of illegal fish and a fifth charge of vehicle ID requirements violation. Additional pending citations for similar violations are expected from the DNR Bureau of Law Enforcement.
