The invasive Asian carp continues to move further north in the Mississippi River.
Minnesota’s D-N-R said yesterday that a silver carp and a big-head carp were found on the river near Winona, about 25 miles northwest of La Crosse. The D-N-R’s Steve Hirsch says his agency has never seen silver carp that far upstream. But he says it’s not a big surprise, because D-N-A samples confirmed a presence of the Asian carp last summer on the Saint Croix River in the Prescott area. The bloated carp threatens native fish on the Mississippi, and cuts into their food chain. The Minnesota D-N-R is building several carp barriers in the Twin Cities area.
