Short description Morfología | Morfometría

Radios blandos dorsales (total): 13; Radios blandos anales: 16. Barilius ardens can be distinguished from B. canarensis and B. malabaricus by having a color pattern consisting of a row of 7-9 large, vertically-elongate, bluish-green blotches 4-6 scales high and 2-3 scales wide along the length of the body, of which in large adults the first three blotches are fragmented into a smaller row of blotches (vs. single or double rows of spots along the length of the body, the first row with 9-13 round or oval bluish-green spots 1-2 scales high and 1-2 scales wide and the second row, if present, with 3-4 smaller spots reaching up to the anal-fin origin). It differs from both B. canarensis and B. malabaricus by having 5+4+3 (vs. 5+4+2) teeth on the fifth ceratobranchial. It further differs from B. canarensis by having 16-18 (vs.14-15) predorsal scales, and having the dorsal and anal fins margined with bright orange (vs. broadly margined with white). In addition, it can be separated from B. malabaricus by having 10½ (vs. 11½) branched dorsal-fin rays and 13½ (vs. 14½-15½) branched anal-fin rays. It can be disinguished from B. bakeri by its unique color pattern, consisting of a row of 7-9 large, vertically-elongate bluish-green blotches 4-6 scales high and 2-3 scales wide along the length of the body, of which in large adults the first three blotches are broken up into a smaller row of intercalate blotches (vs. only a single row of spots along the length of the body); its fifth ceratobranchial with 5+4+3 (vs. 5+4+2) teeth; and the dorsal and anal fins margined with bright orange (vs. white) (Ref. 100448).

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=0.00708 (0.00316 - 0.01588), b=3.05 (2.86 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
