Short description Identification keys | Morphology | Morphometrics

Bases of outer barbels in line with or ahead of inner barbels (Ref. 86798).

Biology     Glossary (e.g. epibenthic)

Occurs in the bottom of main channels and embayments of large turbid rivers; frequently in flowing water over sand and mixed with gravel and mud. Feeds primarily on larvae of aquatic insects (especially burrowing mayflies, caddis larvae and midge larvae (Ref. 10294)), worms, and crustaceans (Ref. 50937). Spawning occurs from April to June in large rivers in areas of swift current and coarse substrates (Ref. 10294).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  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):  3.5   ±0.3 se; based on diet studies.
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (tm=5; tmax=37-43; K=0.13).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (69 of 100).
Price category (Ref. 80766):   Unknown.
