Краткое описание
определительные ключи | морфология | морфометрия
Adults differ from Puntius filamentosus, P. singhala and P. assimilis by possessing prominent black markings on body anterior to anal-fin origin. Distinguished from P. exclamatio by lacking an elongate, tear-shaped black blotch above anal fin. Differs from P. srilankensis by having mouth subterminal and lower lip entire (vs. mouth inferior and lower lip medially absent). Distinguished from P. tambraparniei by lacking branched dorsal-fin rays elongated into filaments in adult males (vs. present) and by having a pair of maxillary barbels <0.5% SL (vs. 2.4-4.7%) (Ref. 55036).
Inhabits large streams, rivers and lakes (Ref. 41236). Omnivorous, peaceful and schooling (Ref. 57467).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00516 - 0.02330), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.7 ±0.1 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
