Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 30 - 34; Anal spines: 2; Anal soft rays: 5 - 6. Vertebral column extends into caudal fin. Black spot near the base of the pectorals. Dorsal posterior margin of operculum slightly toothed.

Biology     Glossary (e.g. epibenthic)

Occupies very diverse biotopes and carries out its biological cycle in freshwater as well as in brackish water (Ref. 27188). Juveniles feed on larvae of crustaceans (especially Macrobrachium), aquatic insects and copepods. Adults prey on fish. Captured during the rainy season (Ref. 35237).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00796 - 0.00953), b=3.08 (3.06 - 3.10), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  4.4   ±0.5 se; based on diet studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.11-0.22; tm=1-1.5).
Fishing Vulnerability (Ref. 59153):  High vulnerability (62 of 100).
Price category (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 47.4 [22.8, 100.6] mg/100g; Iron = 0.868 [0.407, 1.560] mg/100g; Protein = 18.9 [17.6, 20.2] %; Omega3 = 0.344 [0.122, 0.954] g/100g; Selenium = 73.9 [29.6, 172.3] μg/100g; VitaminA = 85.8 [22.4, 311.3] μg/100g; Zinc = 1.18 [0.79, 1.79] mg/100g (wet weight);
