Distinguished uniquely from congeners in Europe by the absence of canine teeth. Differs further by the combination of the following characters: second dorsal fin with 19-21½ branched rays; 70-83 scales on lateral line; and cheek scaled (Ref. 59043).
Inhabits large, turbid rivers and lakes, and brackish coastal lakes and estuaries. Most active at dusk and dawn. Feeds on small fish and invertebrates. 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).

They excavate shallow depressions in sand or gravel, or exposed plant roots where eggs are deposited, usually along shallow shores at 1-2 m depth (Ref. 59043).歐洲: 到窩瓦河與烏拉山脈的河多瑙河。 在伯恩公約的附錄 3 中 (受保育的動物群).
