Etymology: Bagarius: From the local name Vaghari, in Calcuta (Ref. 45335); vegrandis: Name from Latin adjective 'vegrandis' meaning ‘not very large’, referring to the small body size of this species in comparison to its congeners..

Issue
Species data previously under Bagarius bagarius were assumed to refer to B. vegrandis (assumption followed Ref. 123776).

Краткое описание определительные ключи | морфология | морфометрия

позвонки: 39 - 40. This species is distinguished from all its congeners by the following characters: a small maximum body size (to 22.0 cm SL (vs. 52.0-140.0 cm SL) and the adipose-fin origin markedly posterior to the anal-fin origin (vs. at vertical through or very slightly posterior to it); with an ovoid unculiferous plaques on dorsal surface of head; lateral margin of frontal not significantly deflected dorsally; eye diameter 11-15% HL; interorbital distance 23-28% HL; head width 18.3-22.3% SL; head depth 11.1-14.1% SL; filamentous extensions to first pectoral-fin element reaching to anus; dorsal spine width 10.6-13.9 times in its length; body depth at anus 8.7-12.0% SL; neural spines of the 4-6 vertebrae immediately anterior to adipose fin distally flattened but not forming series of prominent bumps along dorsal midline; length of adipose-fin base 10.8-13.0% SL; caudal-peduncle length 19.0-22.4% SL; caudal-peduncle depth 3.2-4.2% SL; preanal vertebrae 19-20 and total 39-40 vertebrae (Ref. 123776).

Adults inhabit rapid and rocky pools of large and medium-sized rivers. Important as a food fish, but the meat spoils rapidly and can cause illness (Ref, 12693).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00307 - 0.01489), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

устойчивость к внешним воздействиям (Ref. 120179): низкий, минимальное время удвоения популяции 4.5-14 лет (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (17 of 100).
