Detail
Basin of northern Black Sea and Sea of Azov: Dnister, South Bug, Dnipro, Don and Kuban drainages. In Dnipro up to Belarus. Flowing waters, also lakes with clear water; in summer in rapids; over sand and gravel bottom but prefers hard compact sand. Spawns in river stretches with heavy current and sand or gravel bottom. Spawns for the first time at 2-3 years, 120-160 mm SL. Spawns in small schools. Female lays slightly sticky eggs in several portions: first at 6-8°C, second at 12-14°C. Eggs hatch in 6-8 days at 14-16°C. Newly hatched larvae first lie on bottom; at 9 days (when pectorals are developed), they actively move to middle water layers and drift downstream. At 12 days (6.5 mm SL), they start active feeding on small invertebrates in shallow shoreline habitats. A benthic species that aggregates in small schools. Usually crepuscular but feeds also during daytime. In September, starts forming large schools and moves to deeper places and remains inactive until ice melts. Does not migrate for long distances. Feeds mainly on benthic invertebrates (crustaceans, insect larvae, molluscs), rarely on small fish.
