Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012
Date Assessed: 2011-02-24
Assessor(s): Baird, I.
Reviewer(s): Rainboth, W. & Smith, K.
Contributor(s): Fisher, J.
The species is widespread, though in slow decline due to the impacts of dams and over harvesting. The species is assessed as Least Concern as the rate of decline is not thought to be near 30% over the past generations (10 to 12 years). It is recommended that the species populations are monitored.

Population [top]

Population:Locally common throughout its range, though in slow decline.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Mostly found in mainstream and larger tributary rivers with sandy bottoms, though migrates (not strictly a breeding migration, migrated to exploit seasonally flooded habitat) into small tributaries and flood plains during rainy season. Clear preference for deep water pools in dry season (Baird et al. 2004).
Movement patterns:Full Migrant

Use and Trade [top]

Use and Trade: An important food fish. The species was one of the most important (1995: 8.8% of total catch; 1998: 3.8% of total catch; 1999: 3.4% of total catch in the Khone Falls wing trap fishery (sixth most abundant by weight) in southern Lao PDR (Baird et al. 2004).

Threats [top]

Major Threat(s): Due to the habitat required by the species and migrations dams have caused the species to decline in certain areas, the species does not survive in reservoirs. Over-harvesting is also a local threat to the species.

Conservation Actions [top]

Conservation Actions: Local fish conservation areas have been developed that help this species (protection of deep water pools).
