Short description
आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण): 1. Diagnosis: large species, up to 300 mm SL or more (Ref. 57127). Anterior nostrils never closer to each other than the posterior ones; inner margin of pectoral-fin spine finely denticulate; 39-70 branched anal-fin rays; 8-15 gill rakers on lower limb of first gill arch; adipose fin always present (Ref. 43912, 57127). Lower jaw reaching as far as or a little shorter than upper jaw; brownish longitudinal stripes along sides and anal fin (Ref. 43912).
Found in riverine and lacustrine conditions; prefers freshwater but has also been recorded from brackish water lagoons in mixohaline water; voracious and carnivorous (Ref. 43912). Feed mainly on (terrestrial) insects (Ref. 6868, 43912) and fish, but also fruits, amphibians, small rodents and Arachnida have been found in stomachs (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205).
Distinct pairing (Ref. 205).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00389 - 0.01070), b=3.11 (2.97 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.49 se; based on food items.
Generation time: 2.4 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
लौटाव (Ref.
120179): ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Assuming fec > 10,000).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (29 of 100).
