Length at first maturity / Size / Weight / Age
Maturity: Lm 58.0  range ? - ? cm
Max length : 200 cm TL male/unsexed; (Ref. 9987); max. published weight: 45.0 kg (Ref. 9987); max. reported age: 10 years (Ref. 56)
Dorsal fin with 12-14 1/2 branched rays; lower profile of head conspicuously arched; short dorsal fin with anterior branched rays shorter than head; 12-16 predorsal scales ; snout without lateral lobe (Ref. 43281).
Adults inhabit rivers (Ref. 4832). A diurnal species and usually solitary. They burrow occasionally. Feed on plants. Spawning season generally coincides with the southwest monsoon. Spawning occurs in flooded rivers. Fecundity varies from 226,000 to 2,794,000 depending upon the length and weight of the fish and weight of the ovary. Widely introduced outside its native range for stocking reservoirs and aquaculture. Utilized fresh (Ref. 9987).
Spawns in middle reaches of rivers, where flood water spreads in more or less limpid shallows over fertile flats, well above tidal reaches; also in reservoirs and bundh-type tanks.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00759 (0.00643 - 0.00894), b=3.09 (3.05 - 3.13), in cm total length, based on LWR estimates for this species (Ref. 93245
Trophic level (Ref. 69278
): 2.2 ±0.12 se; based on food items.
Generation time: 4.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (tm=3; tmax=10).
