Cyprinus carpio widely known as the common carp, is a widespread freshwater fish of eutrophic waters in lakes and large rivers in Europe and Asia. It gives its name to the carp family, Cyprinidae. The common carp is native to Europe and Asia and has been introduced to every part of the world except the poles. They are the third most frequently introduced fish species worldwide, and their history as a farmed fish dates back to Roman times. Carp are used as food in many areas but are also regarded as a pest in several regions due to their ability to out-compete native fish stocks.
