Description

The predatory carp is a large cyprinid from East Asia, including China, the Amur basin and adjacent areas. The species grows to about one metre and has an elongate, laterally compressed, silvery body with a strongly upturned mouth and reddish fins, to which the name refers. Adults inhabit rivers and lakes. Unlike most cyprinids this is a decided predator that hunts insects, crustaceans and smaller fishes, mainly in the upper water layers. The predatory carp is an important commercial fish. It is harmless to humans.
