簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 0; 背的軟條 (總數) : 40 - 46; 臀鰭軟條: 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.
吻長的, 頂端尖的。 下唇不是連續, 在中心中斷。 觸鬚短不達到嘴但是較接近它超過對吻尖。 五個列的鱗甲, 背部的 11-14, 側面的 30-36 在兩邊 , 在兩邊上的腹面 10-11 上, 有小的在主要的鱗甲列之間的多骨星形的碟與較小的穀粒。 背面深灰色的到幾乎黑色的﹐側面顏色較淡﹐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).
主要地發現在沙子與泥上的近岸, 在白天期間停留在底部而且在晚上上升到水表覓食。 主要吃魚，也捕食軟體動物，甲殼動物與蠕蟲。 (參考文獻 3193) 為魚子醬的這三個之一最重要的種; 也生鮮利用與冷凍; 吃油鍋炸的, 火烤的與燒烤。 (參考文獻 9988)
