Mouth oblique. Low wavy lateral line. Belly with a sharp edge (Ref. 35388).
Adults shoal in lower reaches of large rivers and in the eastern Baltic, the Caspian Sea and the Aral Sea. They spawn in spring in midstream (Ref. 9696) and return to estuaries to forage immediately after spawning (Ref. 59043). Juveniles may migrate to estuaries during first summer (Ref. 59043). Feed on zooplankton, terrestrial invertebrates and small fish (Ref. 59043).
