Cyprinus is the genus of typical carps in family Cyprinidae. They are of East Asian origin and closely related to some more barb-like genera, such Cyclocheilichthys and the recently-established Barbonymus(tinfoils). The crucian carps (Carassius) of western Eurasia, which include the goldfish (C. auratus), are apparently not as closely related.
This genus' most widespread and well-known member is the common carp (C. carpio). It is famed as afood fish and widely traded and introduced since antiquity, but in certain areas has multiplied inordinately and become a pest. In some places, such as Australia[verification needed], it is illegal to not kill a Common Carp when you can, due to their severe overpopulation.
