簡短描述
型態特徵 | 形態測量圖
Absence of scalelike scutes on belly; bases of outer barbels usually behind bases of inner barbels (Ref. 86798).
Adults inhabit large, deep, turbid river channels, usually in strong current over firm sand or gravel (Ref. 10294, 58490). They feed on aquatic insect immatures, particularly caddisfly larvae, and small fish (Ref. 10294). Threatened due to over harvesting and habitat loss (Ref. 58490). No length type given but assumed to be in TL.
棲息於大的﹐深的﹐和混濁的河道, 通常在硬沙或礫石上的強水流.(參考文獻 10294,58490) 捕食水生的昆蟲不成熟的, 特別地石蠶幼生 , 與小魚.(參考文獻 10294) 受威脅的捕穫之上由於與棲息地損失.(參考文獻 58490) 給的沒有長度類型但是可能是的體全長。

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00407 (0.00149 - 0.01114), b=3.16 (2.92 - 3.40), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
營養階層 (Ref.
69278): 3.9 ±0.63 se; based on food items.
Generation time: 16.8 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
回復力 (Ref.
120179): 低的, 最小族群倍增時間4.5 - 14 年 (tm=5-15; Fec=170,000, tmax=41(based on 1 specimen only)).
Fishing Vulnerability (Ref.
59153): High to very high vulnerability (67 of 100).
