Justification:
The species has a wide distribution the from Mae Klong in Thailand eastward to the Mekong basin. It has been introduced to Myanmar and the Philippines for aquaculture and is heavily utilised from the wild. However at present there is no evidence of widespread population declines and it is assessed as Least Concern.

Habitat and Ecology [top]

Habitat and Ecology:This species inhabits lowland river mainstreams and tributaries including floodplains, marshland and larger waterbodies. It is well-adaptive to impounded waters. Feeds in mainstream and the Sesan tributary system, lives in deep pools of mainstreams. 'Black' seasonal movement, moving from river channels into seasonally flooded areas (Poulsen et al. 2004).
Systems:Freshwater
Movement patterns:Full Migrant

Use and Trade [top]

Use and Trade: It is a popularly consumed, fished at large and small scales, and found in aquaculture. Juveniles are popular in the aquarium trade and large fish are popular for public aquaria. In Thailand, it is often used in food products.

Threats [top]

Major Threat(s): Overfishing and habitat degradation are potential threats to the species.
