Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal soft rays: 12 - 14; Vertebrae: 52. Distinguished from its congeners by a unique combination of the following characters: head length 30.8-32.4% SL, length of caudal peduncle 15.3-16.1% SL, depth of caudal peduncle 7.8-8.5% SL, dorsal to adipose distance 4.0-7.0% SL, eye diameter 11.5-12.3% HL, 52 vertebrae, and olive green body with orange fins (Ref. 41209).

Inhabits rivers. In Nagarjunasagar reservoir, this species contributed to the commercial fishery to the extent of 1 to 3 t per annum during 1976-80 (Ref. 43629).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00759 (0.00377 - 0.01527), b=2.94 (2.77 - 3.11), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
