Invasive carp moving upstream in MN

Between May 26 and 31, five bighead carp (Hypophthalmichthys nobilis) were caught by anglers in the St. Croix river, near Stillwater, MN.  They notified MN-DNR officials of the presence of the invasive fish, and they were able to catch more of the fish.  This pushes the known range northward seven miles, though they currently don't believe that the carp are breeding in the river.  Bighead carp are not native to the river and directly compete with native fish for plankton and can grow up to sixty pounds.
