背棘 (總數) : 0; 背的軟條 (總數) : 27 - 48; 臀鰭軟條: 16 - 35. Under the name A. g. colchicus. Lower lip not continuous, interrupted at center. 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. Color of back olivaceous grey, flanks lighter, and belly white.
被稱為 A. g 。 colchicus. 下唇不是連續, 在中心中斷。 五個列的鱗甲: 背部的 7-19, 側面的 24-44 在兩邊上, 腹面 6-13 在兩邊上, 與在背部與腹面列之間的比較小星形的骨質板的線。 背面的顏色灰橄欖色的﹐側面顏色較淡﹐與腹部白色的。
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.
主要地在沙子與泥上的海岸附近發現。 通常獨居性的, 但是當過冬的時候成群地移動或在生殖迴游的時候。 偶然地形成魚群。 (參考文獻 3241) 吃軟體動物，甲殼動物與小魚。 (鯷魚，鯡魚, 鰕虎魚) 從五月到六月產卵。 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).歐亞大陸: 黑海，亞速海與裡海, 進入所有的主要河川哪一並未居住其中.(頓河，庫邦河，多瑙河，聶伯河 (稀有的), 第聶伯河) 國際間的買賣限制 ( 引用2, 自從 1.4.98 以後; 公分 附錄 2).
