Description

The Black Sea roach, known in the Caspian region as kutum, is a large, robust cyprinid of the family Cyprinidae reaching about 70 cm. It resembles a stout roach, with a deep, silvery-grey body and a forked tail. It is a semi-anadromous fish: it lives in brackish coastal water of the Black, Azov and Caspian Sea basins and ascends the great rivers in spring to spawn on gravel and water plants. As an omnivore it eats molluscs, crustaceans, insect larvae and some plant material. In the Caspian region the kutum is a valued commercial and sport fish. Globally the species is assessed as Least Concern (LC), though its spawning grounds have declined sharply in places.
