Short description Bestämningsnycklar | Morfologi | Morfometri

Absence of scalelike scutes on belly; bases of outer barbels usually behind bases of inner barbels (Ref. 86798).
Body shape (shape guide): elongated.

Biologi     Ordlista (t.ex. 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. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00407 (0.00148 - 0.01125), b=3.16 (2.93 - 3.39), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (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.
Resiliens (Ref. 120179):  Låg, lägsta populationsfördubblingstid 4,5-14 år (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). 🛈
