Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal soft rays: 79 - 92. Wide fringed membranous maxillary barbel in females; a single patch of vomerine teeth; pectoral-fin spine thin and smooth in females and thin with weak serrations in males (Ref. 12693). Posterior nostril above and behind eye (Ref. 43281).

Inhabits large upland rivers (Ref. 12693) and enters flooded forest (Ref. 9497). Found in rapids and in deep slow reaches (Ref. 37771). Feeds on worms, plants, animal debris and insects. Sold fresh (Ref. 12693).

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=0.00380 (0.00227 - 0.00636), b=3.01 (2.86 - 3.16), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.44 se; based on food items.

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (52 of 100).

Price category (Ref. 80766): Unknown.
