The roach, also known as the common roach, is a fresh and brackish water fish of the Cyprinidae family, native to most of Europe and western Asia. The common roach is found throughout Europe except for the area around the Mediterranean, and its distribution reaches eastward into Siberia. Eastern Europe and Asia have several subspecies, some with an anadromous lifecycle living around the Caspian and Black Seas.
The roach is a small fish, often reaching no more than about 35 cm, maximum 45-50 cm. The body has a bluish silvery colour and becomes white at the belly. The fins are red. The number of scales along the lateral line is 39-48. The dorsal and anal fins have 12-14 rays.
