Short description Morphology | Morphometrics

Diagnosed from all congeners by the combination of the following characters: lateral line complete with 34-36 + 1-2 pored scales; ½ 6/1/ 2½ scales in transverse line on body, ½4/1/1½ on caudal peduncle. Additional distinguishing characters include: body slender, depth 26.0-28.8% SL; pelvic fin length 27.9-31.9% SL, reaching base of branched anal rays 3-8; lower jaw densely tuberculated over dentary, tuberculation extending backwards beyond level of anterior orbit (Ref. 75997).

Occurs in rivers and streams (Ref. 75997). The type locality, Kalu Ganga, has a gravel-pebble bed with fast-flowing water strewn with boulders (Ref. 75997). Sympatric with other cyprinids such as Puntius srilankensis, Puntius martenstyni and Labeo fisheri (Ref. 75997).

Estimates based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00871 (0.00371 - 0.02044), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low vulnerability (14 of 100) .
