| Biology: |
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). |
