St Paul, MN (KROC-AM News)  More concern about the northern movement of invasive fish in Minnesota.

The Minnesota DNR is reporting the discovery of five bighead carp in a stretch of the St. Croix River near Stillwater. The site is about seven miles upstream from where the first discovery was made. It’s also the furthest upstream the fish has been found in the river.The DNR is now conducting intensive sampling to determine if more invasive carp are in the area.

Silver and bighead carp are two of four species of invasive carp now threatening the Mississippi River and other bodies of water.

Populations of bighead and silver carp are established in the Mississippi River and its tributaries from southern Iowa northward. While bighead and silver carp have been found as far north as Hastings, there is no evidence bighead or silver carp are reproducing in the Minnesota waters of the Mississippi or St. Croix rivers.

The DNR reminds anyone who catches a bighead, silver, black, or grass carp to immediately contact the DNR at 888-646-6367.
