Biologia     Glossario (es. epibenthic)

Prefers quiet stretches of river channels, deep pools and floodplain lagoons with aquatic vegetation; may form small shoals; feeds mainly on insect larvae, shrimps, small snails and small fish (Ref. 52193). Known to move up tributaries when they come down in spate and may breed in newly inundated areas (Ref. 13337). Spawns during the rainy season; females carry up to 7,000 eggs; caught by subsistence fishermen and anglers (Ref. 7248, 52193).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00573 - 0.02198), b=2.83 (2.67 - 2.99), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.61 se; based on food items.
Generation time: 1.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (K=0.8).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (23 of 100).
Price category (Ref. 80766):   Unknown.
