Distribution: Dniepro-Bugskiy liman in the north-western Black Sea, lower reaches of rivers of Dniester, South Bug, Dniepr (Ukraine), Kamchia and Rezovska rivers (Bulgaria), Caspian Sea.
Habitats type, Critical habitats, Limiting factors: Cannot stand both salting and freshening. It is critical habitat is the spawning surface. The main limiting factors are the reduction of habitat and spawning areas, and the decline in food (Gobiidae) stocks.
Biology: Brackish pelagic carnivore fish feeding mainly on Atherina and Gobiidae. Does not tolerate significant salinity and freshening of waters. Spawning occurs from mid April to May in the estuarine parts of the sea, lower reaches of rivers, limans.
Population trends: At the end of the XIX century it was a mass species.Significant catch reduction since the 1950s.
Threats: Degradation of habitats and spawning areas as a result of changes in the hydrological regime and the hydrochemical composition of runoff and pollution, hydrotechnical construction and over fishing.
Conservation measures taken: Included in the Red Data Book of Ukraine, 1994, Bulgaria and the Black Sea. The biotechnics of cultivation in Krasnovodsk (Turkmenistan) has been prepared.
Conservation measures proposed: Reduction in Black sea coastal zone pollution, especially in the Dnieper-Bug estuary as a main breeding and feeding area. Artificial reproduction of this species.
