deskripsi pendek Morfologi | Morfometrik

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

Biologi     Daftar kata (contoh 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).
Trophic level (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.
Daya lenting (Ref. 120179):  Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (tm=5-15; Fec=170,000, tmax=41(based on 1 specimen only)).
keancaman (Ref. 59153):  High to very high vulnerability (67 of 100) .
