Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 1; Radios blandos dorsales (total) : 6 - 7; Espinas anales: 0; Radios blandos anales: 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.

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).

Nivel trófico (Ref. 69278): 2.7 ±0.29 se; based on food items.

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (49 of 100).
