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).
Body shape (shape guide): elongated.
Body shape (shape guide): elongated.
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).
生命周期和交配行为 成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
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。
