The sharpbelly, Hemiculter leucisculus, wild carp, Korean sharpbelly, or common sawbelly is a tropical freshwater and brackish water fish belonging to the Cultrinae subfamily of the Cyprinidae family. It originates in large streams and reservoirs in China, Japan, Hong Kong, Korea, and the Amur River basin. It has become established as an exotic species in several other countries, including Iran, Afghanistan, and the former Soviet Union, where it has displaced local species. It was originally described as Culter leucisculus by S. Basilewsky in 1855, and has also been referred to as Chanodichthys leucisculus and Hemiculter leucisculus warpachowskii in scientific literature.
