Caspian roach

The Caspian roach (Rutilus caspicus) is a species of roach fish living in the Caspian Sea. The Caspian roach can be distinguished from other roaches by its laterally compressed body, silvery grey iris, rounded snout and grey pectoral pelvic and anal fins with dark margins. The Caspian roach is semi-anadromous and inhabits mostly shallow coastal waters. It enters Volga, Ural, Emba, Terek and Kura drainages for spawning.Newer research however suggests that R. caspicus is part of a more widely distributed species or roach, whose range extends to Siberia. The proper name of that species is Rutilus lacustris.
