Length at first maturity / Size / Weight / Age

Maturity: Lm ?, range 24 - ? cm
Max length : 108 cm TL male/unsexed; (Ref. 40637); common length : 70.0 cm TL male/unsexed; (Ref. 9987); max. published weight: 40.0 kg (Ref. 72380)

Biology     Glossary (e.g. epibenthic)

This species is usually solitary. Adults stay in flooded forests during first 5 months of flooding and consume but fruits and grains. Young and juveniles live in black waters of flood plains until their sexual maturity. Feeds on zooplankton, insects, snails and decaying plants (Ref. 32894). Used in aquaculture because it can live in mineral poor waters and is very resistant to diseases. Marketed fresh and frozen (Ref. 9987).

Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02239 (0.01185 - 0.04230), b=2.99 (2.82 - 3.16), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.0 se; based on diet studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.23; Fec=7,000-300,000).
