簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 10; 臀鰭軟條: 9; 脊椎骨: 40 - 42. Branched anal rays 6 1/2; branched dorsal rays 7 1/2; longitudinal epithelial crests on predorsal scales; lateral line scales 40-42 + 1-2; circumpeduncular scale rows 10-12; caudal peduncle depth larger than its width at base of last anal rays; caudal peduncle depth 2.9-4.3 times in its length; eye diameter 1.1-1.6 times in interorbital distance; dorsal fin behind middle of body, postdorsal distance 87-97% of predorsal distance; anus midway between pelvic and anal origins; snout 80-98% of postorbital distance; supraorbital and infraorbital sensory canals connected; posterior neurocranium width 59.6-68.6% of cranium roof length; anterior neurocranium width 22.8-29.3% of cranium roof length (Ref. 52363). Aside for these characters, other diagnostic characters to separate this species from its congeners in Black and Caspian Sea basin include eye diameter 1.0-1.4 times in interorbital distance and greatest head width 52-59% of dorsal head length (Ref. 59043).
分枝的臀鰭鰭條 61/2; 分枝的背鰭鰭條 71/2; 在前背的鱗片上的縱向的上皮冠; 側線鱗片 40-42+1-2; circumpeduncular 鱗片列 10-12; 尾柄深度大於在最後臀鰭鰭條的基底的它的寬度; 尾柄深度 2.9-4.3 倍於體長; 眼直徑 1.1-1.6個倍眼間距; 在身體的中央後面的背鰭, 後背的距離 87-97% 的前背距離; 在腹鰭與臀鰭起點之間的肛門中途; 吻 80-98% 的眼眶後的距離; 眶上而眶下的感覺管連接; 在後部的腦顱寬度 59.6-68.6% 的頭蓋頂部長度; 前面的腦顱寬度 22.8-29.3% 的頭蓋頂部長度.(參考文獻 52363)
Found in turbid waters with very strong current (Ref. 52363). Occurs in large, high-gradient river stretches with fast but not turbulent current and gravel or sand bottom. Active at night where it stays near shore on mud or sand bottom. Feeds on benthic invertebrates, mainly Trichoptera larvae. Appears to spawn late and to have a long spawning period. Many small juveniles are observed in July (Ref. 59043).
