Larvae and juveniles are pelagic and feed on zooplankton. Attains first sexual maturity at 3-4 years of age and 20-30 cm SL. Spawns in April-May. May undertake short spawning migrations (Ref. 59043).

Country info:  Occurs manily in the basins of the Volga, Ural, Don Dnieper and other rivers. It is intensively dispersed into reservoirs where it can be quite abundant (Ref. 26334). This has been translocated to areas within the country, rapidly expanded its range and is now widely established in the country (Ref. 45022). EurRus
