Still more or less abundant in lower reaches of rivers and coastal lagoons. Decline in habitat quality in suitable estuarine ecosystems (limans) in northern Black Sea basin expected to have an impact in the immediate future. However it is not thought that this will cause a population decline by over 30% in the next 10 years.

|Population:||Common within the species range.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||
At sea, pelagic in deep water, entering brackish lagoons to spawn.
Spawns first at two years. Many individuals spawn 2-4 seasons. In Romania, spawners enter Lake Razelm when temperature reaches about 7°C, in March. Spawning starts when temperature reaches about 15°C, in late April-June. Eggs sink to bottom. Spent fish return to sea to feed. In autumn, migrates to southern Black Sea to overwinter. Juveniles migrate to sea or remain in estuaries during first summer. Feeds predominantly on small fish and crustaceans.
|Movement patterns:||Full Migrant|
|Major Threat(s):||Water abstraction leading to increasing salinity of the limans (coastal lagoons) where the species spawns is a potential threat to the species.|
|Conservation Actions:||No information.|
