|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.
