Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 6 - 7; Anal spines: 0; Anal soft rays: 17 - 24.

Adults inhabit rivers and lakes to at least 400 m elevation (Ref. 2847) at temperatures ranging from 26 to 32°C. May have migratory habits. Mainly diurnal. They feed primarily on large insect larvae and emergent and terrestrial insects, and also crustaceans excluding prawns.

Observations though on mouthbrooding are lacking. Ovary contains 25 to 90 ripe eggs (Ref. 2847).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00537 (0.00327 - 0.00882), b=3.22 (3.07 - 3.37), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 2.7 ±0.29 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 to high vulnerability (49 of 100).

Price category (Ref. 80766): Medium.
