They might be on their way, but a new study finds Asian carp are not living in Minnesota in any significant numbers.

Researchers with the state and federal governments and the U of M found no DNA from the invasive fish in the Mississippi or St. Croix Rivers in Minnesota.

The DNR is urging against complacency, though, emphasizing that the threat posed by Asian carp is urgent and requires immediate action.

Silver and bighead carp devour plankton -- growing to 100 pounds -- and reproduce quickly, making them a threat to crowd out native fish.

A separate report also issued Thursday studied the Great Lakes. It concluded that there likely are some Asian carp in the lakes, particularly southern Lake Michigan, but that it's not too late to fend off an infestation and protect the $7 billion fishing industry.
