简单描述 型态特徵 | 形态测量图

Differs from Ballerus sapa by having superior mouth, 62-77 scales on lateral line, and small eye with diameter about 2/3 of snout length in individuals larger than 10 cm SL (Ref. 59043).

生物学特性     字汇 (例如 epibenthic)

Occur in large lowland rivers with backwaters and also in eutrophic lowland lakes. Feed mainly on zooplankton in open water of backwaters and other still water bodies. Spawn along shores of rivers or in backwaters on submerged vegetation and also on gravel in moderate current. Migrate upriver in long distances to suitable spawning sites. Juveniles stay in backwaters and flooded zones along rivers. Enter freshened parts of seas to forage. Life span reaches more than 10 years. Locally threatened by habitat alterations along river banks (Ref. 59043).

栖息于大河的下面范围。 主要吃浮游生物。 在春天溯河回游而且产卵。 (参考文献 9696)

Mostly spawn several times during their life. Spawning lasts usually for 1-2 weeks. Female spawn once a year. Male often guard spawning territories along the shoreline (Ref. 59043).歐亞大陸: 波羅的海,黑海,亞速海北方與裡海的流域。 伯恩公約的附錄 3(受保育的動物群).
