The Minnesota Department of Natural Resources says it will conduct test netting this fall on Lake Pepin and other parts of the Mississippi River. They'll be looking for Asian Carp after a commercial fisherman pulled a 23-pound bighead carp out of the lake last week, marking the first time the invasive species has been confirmed in Minnesota waters. The bighead is related to the silver carp, which has made news because it can reach 110 pounds and jump several feet into the air. Both species have been moving north in the Mississippi and its tributaries since the 1980s, after they were imported by Arkansas fish farmers and were either released or escaped.
