Voracious carp Could Quickly Take Over Great Lakes

: There are four species of Asian carp that are considered invasive and a threat to the Great Lakes: bighead, silver, black and grass. So far, evidence of silver and bighead has been found near Lake Michigan. Both filter plankton in the water into their mouths at an alarming rate, leaving little for other fish or organisms.

Bighead carp can grow to more than 5 feet long and can weigh 80 pounds or more.
