A Republican state lawmaker is circulating a bill to control sea lamprey, eel-like parasites that attack trout and other fish in the Great Lakes.
State Sen. Robert Cowles of Green Bay wants to provide funding to the state Department of Natural Resources to combat the "rotten invasive species."
Environmental groups say they're less concerned with lamprey than with other invasive species, but they're not opposed to the bill.
A Wisconsin State Journal report says the bill would fund the DNR to increase lamprey management in Lake Michigan and Lake Superior. It would also provide money to fix a lamprey barrier on the Kewaunee River in northeastern Wisconsin and build another barrier on the Nemadji River, which flows into Lake Superior.
