Short description Morfologia | Morfometria

Spine dorsali (totale): 1; Raggi dorsali molli (totale): 7; Raggi anali molli: 12 - 14; Vertebre: 43 - 44. Can be differentiated from its congeners by a unique combination of the following characters: adipose fin short (length of adipose-fin base 11.3-12.7% SL; 1.72-2.20 times maximum adipose height) with a steep anterior margin (length of adipose-fin base and a distinct black spot on the posterior half); head width 20.6-23.4% SL; dorsal to adipose distance 12.7-16.2% SL; and absence of filamentous extensions on the first three dorsal-fin rays in adults.

Feeds on exogenous insects, aquatic insect larvae, shrimps and other crustaceans, as well as fishes. In Cambodian Mekong, it moves into flooded forest to spawn and the young are first observed in August, with the adults returning to rivers in November and December.

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=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.6 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (28 of 100).
