背棘 (总数) : 0; 背的软条 (总数) : 40 - 46; 臀鳍软条: 24 - 29. Snout long, pointed at tip. Lower lip not continuous, interrupted at center. Barbels short not reaching mouth but nearer to it than to tip of snout. Five rows of scutes, dorsal 11-14, lateral 30-36 on each side, ventral 10-11 on each side, with small bony stellate plates and smaller grains between main scute rows. Back dark grey to almost black, flanks lighter, belly white.
吻长的, 顶端尖的。 下唇不是连续, 在中心中断。 触须短不达到嘴但是较接近它超过对吻尖。 五个列的鳞甲, 背部的 11-14, 侧面的 30-36 在两边 , 在两边上的腹面 10-11 上, 有小的在主要的鳞甲列之间的多骨星形的碟与较小的谷粒。 背面深灰色的到几乎黑色的，侧面颜色较淡，和腹部白色的。
At the sea, it occurs in coastal and estuarine zones and forages on the bottom mostly on clayey sand and intensively in the middle and upper water layers (Ref. 59043). Found mainly near shore over sand and mud, stays at the bottom during the day and rises to the surface to feed at night. Feeds mainly on fish, also mollusks, crustaceans and worms (Ref. 3193). Spawns in strong-current habitats in main course of large and deep rivers, on stone or gravel bottom. Spawning also takes place on flooded river banks and if gravel bottom is not available, on sand or sandy clay. Juveniles stay in shallow riverine habitats during first summer (Ref. 59043). One of the three most important species for caviar; also utilized fresh and frozen; eaten pan-fried, broiled and baked (Ref. 9988). Overfishing at the sea for meat and caviar will soon cause extinction of the natural populations and their survival can only depend on stocking (Ref. 59043).
主要地发现在沙子与泥上的近岸, 在白天期间停留在底部而且在晚上上升到水表觅食。 主要吃鱼，也捕食软件动物，甲壳动物与蠕虫。 (参考文献 3193) 为鱼子酱的这三个之一最重要的种; 也生鲜利用与冷冻; 吃油锅炸的, 火烤的与烧烤。 (参考文献 9988)
