Watch your heads, Minnesota boaters: Asian carp have arrived
|Commercial fishermen hold Asian carp caught March 1 in Mississippi River near Winona. From left to right, the fish are grass carp, silver carp, and bighead carp.|
Recent reports make the invasive fish sound like villainous creatures from a sci-fi flick -- "the silver carp is known to jump out of the water and strike boaters in the head," MPR notes; according to the EPA, reported injuries from flying silver carp include "cuts from fins, black eyes, broken bones, back injuries, and concussions."
Not only can Asian carp lay the smack down on humans, but they mess up ecosystems as well. Bighead carp can weigh up to 100 pounds, silver carp up to 60, and the voracious eaters can easily out-compete native fish for scarce food supplies.
In response to the Asian carp threat, Gov. Mark Dayton is pushing legislators to approve funding for construction of a new fish barrier at the Coon Rapids Dam. Dayton, writing last week in an Outdoor News editorial, said, "we continue to explore emergency closure of the St. Anthony Falls lock, should that be our last line of defense in a critical situation."
On the heels of last week's discovery of silver carp and bighead carp near Winona, Steve Hirsch, the DNR's Eco-Waters Division director, characterized the need for the state to take containment action as "urgent."

Referencing the experience of other states that have dealt with the invasive carp, Hirsch said: "As these fish moved up they went through a period like what we're going through now where they would occasional see big fish and it would start to become more and more common and it seems like they reach a threshold and then they start reproducing and they become abundant."
In other words, in addition to poles and life jackets, if state officials don't find a way to contain Asian carp sooner than later, anglers might also have to pack helmets when they hit Minnesota lakes connected with the Mississippi River.
