Europe: Dniestr and tributaries of lower and middle Danube drainage (Black Sea basin); upper Vistula drainage in Poland (Baltic Basin). Systematics of sand gudgeon has not been resolved and several species seem to be confused under the name of Romanogobio kesslerii.

簡短描述

背棘 (總數) : 3; 背的軟條 (總數) : 8 - 9; 臀棘: 2; 臀鰭軟條: 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
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
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.(參考文獻 1441) Dniestr 與下游的與中游多瑙河流域 (黑海流域) 的支流; 在波蘭的上面 Vistula 流域 (波羅的海流域.(參考文獻 59043)
