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).
