Korte beschrijving
Determinatiesleutels | Morfologie | Morfometrie
Dorsale stekels (totaal) : 1; Dorsale zachte stralen (totaal) : 7; Anale stekels: 0; Anale zachte stralen: 11 - 12. Body elongate and compressed; snout broad and spatulate. Barbels extend posteriorly to pelvic fins or beyond to anal fin. Dorsal spine weakly serrated on its posterior edge; adipose fin base short, about as long as the rayed dorsal fin base. Color is brownish-gray on back, silvery on flanks and belly. A dark well-defined spot is on the adipose dorsal fin.
Found in rivers, canals, beels, ditches, inundated fields and other freshwater areas. Adults fight well and provide good sport. Carnivore. Breeding occurs before the commencement of monsoons. Oviparous, distinct pairing possibly like other members of the same genus (Ref. 205).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00644 - 0.00936), b=2.91 (2.86 - 2.96), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.8 ±0.1 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Fec = 20,064).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (90 of 100).
Nutrients (Ref.
124155): Calcium = 82.3 [25.9, 180.8] mg/100g; Iron = 0.933 [0.496, 1.681] mg/100g; Protein = 16.8 [15.2, 18.4] %; Omega3 = 0.116 [0.056, 0.243] g/100g; Selenium = 84.6 [43.7, 171.3] μg/100g; VitaminA = 12.4 [3.3, 41.2] μg/100g; Zinc = 0.333 [0.211, 0.550] mg/100g (wet weight); based on
nutrient studies.
