Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012

A common species is recorded from the Chao Phraya River and the Mekong basin. It is highly utilised and impacted by habitat loss, but is assessed as Least Concern at present as there is no evidence at present of significant population declines across its range. Impacts from potential future mainstream dams should be monitored.

Population [top]

Population:This species is common. It is the sixth most common species in the wet season wing trap fishery at the Khone Falls in southern Lao PDR, making up 3.8% of the catch (Baird et al. 2004), however catches at the Khone Falls have declined.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Found in mainstreams and larger tributaries, seasonally moving up to flooded areas for feeding during its subadult and juvenile stages. The species migrates upstream in the Mekong in May and June, triggered by hydrological changes, which mainstream dams would impact (Baird et al. 2004; Baran et al. 2005). The species feeds heavily on flooded forest fruits and leaves in the wet season (Baird 2007). Spawning occurs upstream with juveniles and young adults nursing in floodplains ('white' type river migration pattern) (Poulsen et al. 2004).
Movement patterns:Full Migrant

Use and Trade [top]

Use and Trade: This species is widely consumed throughout its range. Popularly bred and cultured in cages, and some farms hybridise it with Pangasianodon hypophthalmus for better performance. It is well-known in the markets as Basa fish or Dory in fillet products (imitating marine Dory Zeus spp.). Fry for aquaculture is taken from the wild.

Threats [top]

Major Threat(s): Overfishing and genetic contamination by hybrids are threats to this species, and impacts of dams throughout its range. Loss of habitat, particularly its flooded forest habitat.

Conservation Actions [top]

Conservation Actions: Monitoring of habitat and population trends is needed. The species benefits from conservation of deep pool dry season habitats in the Mekong.
