COTTAGE GROVE, Minn. - Invasive carp continue to spread up the Mississippi River despite efforts to block them.

The Minnesota Department of Natural Resources said commercial fishermen netted two adult invasive carp in what's known as Pool 2 in Cottage Grove on Thursday.

One was a bighead carp that weighed about 40 pounds. The other was a silver carp, which are the ones that leap from the water when disturbed. That carp weighed about 20 pounds.

Until now, bighead carp had not been detected above the mouth of the St. Croix River near Prescott, Wis. Silver carp had not been detected above Pool 5A near Winona.

Both of the carp found were females that contained eggs, which makes the discovery particularly alarming.

The DNR will continue its invasive carp sampling efforts next week in an effort to determine if more or smaller invasive carp are in the area.
