Etymology: Bagarius: From the local name Vaghari, in Calcuta (Ref. 45335).
More on author: Hamilton.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; brackish; benthopelagic; pH range: 6.5 - 7.8; dH range: 12 - 30; potamodromous (Ref. 51243). Tropical; 18°C - 25°C (Ref. 2060)
Asia: Ganges, Mekong and Chao Phraya basins (Ref. 27732). Reported from Salween, Maeklong and Peninsular Thailand (Ref. 26336).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 200 cm TL male/unsexed; (Ref. 26563)
soft rays: 13 - 14;
Vertebrae: 38 - 42. Pelvic-fin origin in front of the base of the last dorsal ray; adipose-fin origin behind the anal-fin origin (Ref. 27732). Elongate neural spines 4-8, distally expanded abdominal vertebrae 17-20 (Ref. 35669). Absence of sharp ridge on top of head; absence of bumps on dorsal mid-line behind dorsal fin base (Ref. 43281). Mouth large, inferior and arciform (Ref. 45563).
Adults inhabit rapid and rocky pools of large and medium-sized rivers (Ref. 12693). Feed on insects (Ref. 4833), small fishes, frogs and shrimps (Ref. 1479). Breed in rivers prior to the beginning of the annual flood season. Marketed fresh. Important as a food fish, but the meat spoils rapidly and can cause illness (Ref. 12693). Reported length of 200 cm (Ref. 4537) is incorrect (Maurice Kottelat, pers. comm. with hint to Roberts 1982 (not seen).

Bayesian length-weight: a=0.00468 (0.00294 - 0.00745), b=3.02 (2.89 - 3.15), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.7 ±0.59 se; based on food items.
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
