Description synthétique Morphologie | Morphométrie

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

Biologie     Glossaire (ex. 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).
Niveau trophique (Ref. 69278):  3.5   ±0.3 se; based on diet studies.
Résilience (Ref. 120179):  Très faible, temps minimum de doublement de population supérieur à 14 ans (tm=5; tmax=37-43; K=0.13).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (69 of 100).
