Five rows of scutes: dorsal 7-19, lateral 24-44 on each side, ventral 6-13 on each side, with lines of smaller stellate bony plates between the dorsal and ventral rows.

被称为 A. g 。 colchicus. 下唇不是连续, 在中心中断。 五个列的鳞甲: 背部的 7-19, 侧面的 24-44 在两边上, 腹面 6-13 在两边上, 与在背部与腹面列之间的比较小星形的骨质板的线。 背面的颜色灰橄榄色的，侧面颜色较淡，与腹部白色的。
Anadromous and freshwater populations exist. At the sea, it occurs in shallow coastal and estuarine zones. In freshwaters, it inhabits deep parts of large rivers with moderate to swift current (Ref. 59043). Found mainly near the shore over sand and mud. Usually solitary, but swarms when hibernating or during spawning migrations. Occasionally forms schools (Ref. 3241). Feeds on benthic molluscs, crustaceans and small fishes. Spawns on stone or gravel bottom in large and deep rivers with strong current, 1-1.5 m/s (Ref. 59043). Mainly propagated through artificial reproduction.
主要地在沙子与泥上的海岸附近发现。 通常独居性的, 但是当过冬的时候成群地移动或在生殖回游的时候。 偶然地形成鱼群。 (参考文献 3241) 吃软体动物，甲壳动物与小鱼。 ( 鱼，鲱鱼, 鰕虎鱼) 从五月到六月产卵。 主要地以人工繁殖方式繁殖了。
Under the name A. g. colchicus. Spawns in rivers. Natural spawning not extensive, maintained chiefly by artificial propagation. Enters rivers from April to June (a few in autumn).欧亚大陆: 黑海，亚速海与里海, 进入所有的主要河川哪一并未居住其中.(顿河，库邦河，多瑙河，聂伯河 (稀有的), 第聂伯河) 国际间的买卖限制 ( CITES2, 自从 1.4.98 以后; CMS 附录 2).
