DNR Takes Action on Asian Carp

Invasive Asian carp, large, plankton-feeding fish moving northward in the Mississippi River, pose a threat to Minnesota’s rivers and lakes. While no breeding populations have been detected in Minnesota waters of the Mississippi, individual fish have been caught near the Twin Cities and in the St. Croix River.

The Minnesota Department of Natural Resources (DNR) has been working to slow the spread of Asian carp since the early 2000s, but began a renewed effort starting in 2011 under the direction and leadership of Gov. Mark Dayton and DNR Commissioner Tom Landwehr. By working with partner agencies, conservation groups and federal officials, the DNR hopes to stop or significantly slow the proliferation of Asian carp in Minnesota waters.

Above is a close-up of a bighead carp (top) and a silver carp. They eat huge amounts of plankton and detritus. Because they feed on plankton, these fish compete for food with native organisms including mussels, larval fishes, and some adult fish such as paddlefish. This competition for food could result in fewer and smaller sport fish.

Silver carp are shown jumping out of the water in the Illinois River. Silver carp can jump up to 10 feet out of the water when disturbed by sounds of watercraft. They often jump into boats and can injure boaters, personal watercraft operators, and water skiers.
