The Volga bream (spawning population) varies in length from 17-49cm and weighs 170- 2,060g. It inhabits 3 types of water bodies during its life span: rivers, delta-front of the Volga River, and shallow areas of the Caspian Sea. It spawns at the low floodplains during spring flood season and feeds in the delta-front and sea. The most abundant are populations in the Volga and Ural Rivers. Freshwater forms also exist as well.
The Volga bream occurs at feeding grounds of water salinity up to 14%. Its diet consists of mollusks, crustaceans, worms, Chironomidae, plants, sediment and insects. Eggs are deposited on aquatic plants as well as on drifting remains of aquatic vegetation. Due to their adhesive membrane, eggs stick to plants. Typical spawning sites are temporarily flooded water bodies, low-floodplains and lakes.
