背棘 (总数) : 3; 背的软条 (总数) : 8 - 9; 臀棘: 2; 臀鳍软条: 6. Diagnosed from its congeners in Baltic and Black Sea basins by the possession of the following characters: predorsal scales with longitudinal epithelial crests; scale rows between lateral line and pelvic origin 3; scale rows around caudal peduncle 12; dorsal fin with 8½ branched rays; anal fin with 6½ branched rays; eye small, diameter 20-28% HL, 1.0-1.3 times in interorbital distance; body depth 14-21% SL (Ref. 59043).
Adults inhabit fast-flowing piedmont rivers with large areas of sand bottom. They live in groups. Juveniles and adults are active during day. Preyson a variety of benthic invertebrates, usually catching drifting prey. Spawning occurs in shallow areas over gravel, sand or plant material in fast-flowing water. Gradual decline is expected due to on-going economic development. Are sensitive to organic pollution (Ref. 59043).
Life cycle and mating behavior

Both sexes move to surface or open water to spawn. Eggs are released in successive portions and drift with current, sink to bottom and stick to substrate (Ref. 59043).歐洲: 奧地利，保加利亞，克羅埃西亞，捷克，匈牙利，羅馬尼亞，斯洛伐克亞，斯洛維尼亞，南斯拉夫，波蘭，摩爾多瓦與烏克蘭。
