Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 5 - 6; Anal spines: 0; Anal soft rays: 89 - 105.

Found in rivers and smaller streams, usually where currents are relatively swift (Ref. 5259). Also lives in still or gently flowing water of pools and side channels. A solitary species (Ref. 44894). Feed on mollusks, insects, prawns (Ref. 5259, 44894) crustaceans and worms (Ref. 44894). Spawning period coincides with the rise of the monsoonal floods (Ref. 38147, 44894). Adults migrate upstream into shallow riffle zones where they spawn in pairs. The demersal eggs lodge in crevices on the bottom and hatch 2-3 days later (Ref. 44894).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00468 (0.00209 - 0.01049), b=3.06 (2.86 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.44 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (37 of 100).

Price category (Ref. 80766): Unknown.
