簡単な記述 形態学 | 形態計測学

Absence of scalelike scutes on belly; bases of outer barbels usually behind bases of inner barbels (Ref. 86798).

生物学     用語集 (例 epibenthic)

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.

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 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).
栄養段階 (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):  低い, 4.5年~14年の倍増期間の最小個体群 (tm=5-15; Fec=170,000, tmax=41(based on 1 specimen only)).
弱み (Ref. 59153):  High to very high vulnerability (67 of 100) .
