[Invasive species home page]

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.
