Descrição suscinta Chaves de identificação | Morfologia | Morfometria

Raios dorsais (total) : 10; Raios anais : 25 - 27. Head upturned; no barbels; belly with sharp keel from throat to anus (Ref. 43281). Body strongly compressed; dorsal profile flat except concave nape. Mouth directed upward. Pectoral fins elongated. Base of caudal fin with black blotch (Ref. 4792). Lower jaw protruded, tip of it hooked and inlaid into gap of upper jaw; scales minute and irregularly arranged (Ref. 45563).

Found in large rivers and lakes at medium to shallow depths. Juveniles feed on insects while adults on fish (Ref. 12693). Move towards the flooded forest when the water is high and returns to the river as soon as the water level starts to subside (Ref. 12693). Good flesh but fairly soft and with numerous bones. In Laos, it is usually grilled, simmered with padek and made into Ponne pa. Usually marketed fresh and probably exported to Thailand (Ref. 12693). Widely distributed but greatly reduced in numbers probably throughout its range. Extremely sensitive to gillnetting and perhaps also to pollution (Ref. 12369).

Estimates based on models

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00617 (0.00292 - 0.01304), b=3.08 (2.91 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.7 ±0.57 se; based on food items.

Resiliência (Ref. 120179): Muito baixo(a), tempo mínimo de duplicação da população maior que 14 anos (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (60 of 100).

Categoria de preço (Ref. 80766): Unknown.
