Overview
The Common Carp Common carp (Cyprinus carpio) are domesticated ancestors of a wild form native to the Caspian Sea region and east Asia. Carp degrade shallow lakes by causing excessive turbidity, which can lead to declines in waterfowl and important native fish species. The common carp was introduced by unintentional release in 1879.

COMMENTARY: Trying hard not to find Asian carp
The Plain Dealer (4/3)
Experts say it’s a mistake to conclude that if we don't catch a live Asian carp in the Great Lakes, it's not there. For example, if you spend hours on Lake Michigan fishing for salmon and don't catch one, that doesn't mean they're not there.
