Record number of invasive silver carp caught in upper reaches of Mississippi River

Commercial fishermen caught the highest number of silver carp ever found so far upstream in the Mississippi River this week.

The catch shows that the invasive fish are on the cusp of becoming intractable in Minnesota and Wisconsin, and have been gathering below one of the last barriers left between them and the upper Mississippi, Minnesota and St. Croix rivers.

The fishing operation pulled up 30 silver carp on Monday downstream of Lock and Dam 5 near Winona, Minn. They were all about the same age - seven years old - and likely passed a series of locks and dams together during the 2019 floods to make it so far north, said Heidi Wolf, a section manager for the Minnesota Department of Natural Resources.
