生態學
; 淡水; 半鹹淡水 底中水層性; pH range: 6.0 - 8.0; 河川洄游 (Ref. 51243); 深度上下限 1 - ? m. 溫帶; 4°C - 22°C (Ref. 41616); 72°N - 41°N, 10°W - 155°E
Europe and Asia: North, Baltic, White and Barents Sea basins; Caspian basin, in Volga and Ural drainages; Black Sea basin, from Danube to Dniepr drainages; Atlantic basin, in Seine drainage; Mediterranean basin from Rhône to Arch drainages (France). Only very localized in Danube main river in Romania, in Scandinavia north of 69°N and most of cenral Finland. Populations from Siberia and East Asia usually referred to Leuciscus leuciscus are distinct species, Leuciscus baicalensis and Leuciscus dzungaricus (Ref. 59043). Has become widespread in Europe and gained access to Ireland as a bait fish. At least one country reports adverse ecological impact after introduction (Ref. 1739).
歐洲與亞洲: 已經在歐洲變得廣泛分佈而且進入愛爾蘭作為一個誘餌魚.(參考文獻 1739) 至少一個國家報告引入後的不利的生態衝擊。

Diagnosed from congeners in Europe by the following characters: subinferior or subterminal mouth; subequal jaw, upper jaw slightly longer; upper lip tip about level with center of eye; not projecting snout; articulation of lower jaw distinctly behind anterior margin of eye; horizontal branch of preoperculum shorter than vertical branch; and 40-50 + 1-2 scales on lateral line (Ref. 59043). Rarely longer than 30 cm TL; normally 47-52 scales in lateral line; anal fin concave; caudal fin forked with 19 rays (Ref. 41616).
很少長度超過 30 公分TL; 通常在側線中的 47-52個鱗片; 臀鰭凹曲; 尾鰭以19個鰭條分岔。
Gregarious fish which swims near the surface (Ref. 30578). Inhabits moderate to fast-flowing large streams to large rivers with rock or gravel bottom. Adults aggregate in dense swarms in winter in the lower reaches of rivers or backwaters and often migrate to spawning streams in autumn and overwinter there. Juveniles spend winter in cavities along the shores. Early juveniles occur in very shallow shoreline habitats and when they grow, they leave the shores for faster-flowing waters. Feeding larvae thrive along shores. Prey on small invertebrates. Spawns in fast-flowing water on shallow gravel beds, often in small tributaries (Ref. 59043). Breeds in March and April (Ref. 30578). Pale yellow eggs are found attached to gravel and stones in shallow, flowing water (Ref. 41678).
在表面巡游的群居的 魚.(參考文獻 30578) 偏愛河與清澈寒冷的湖上面範圍。 吃昆蟲，蠕蟲，蝸牛, 與很少地植物。 在波羅地海東部中進入半淡鹹水。 繁殖發生於三月與四月。 (參考文獻 30578) 淡黃色的卵被發現在流動的淺灘中依附於礫石與石頭。 (參考文獻 41678)
Regularly undertake migration of some tens of km to spawning sites, which are often situated in tributaries. Males form large aggregations, each male defending a small territory. Females lay sticky eggs into excavaitons made in gravel (Ref. 59043).歐洲與亞洲: 已經在歐洲變得廣泛分佈而且進入愛爾蘭作為一個誘餌魚.(參考文獻 1739) 至少一個國家報告引入後的不利的生態衝擊。
