Scientific Name: Schistura khamtanhi Kottelat, 2000

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2012
Date Assessed: 2011-01-20
Assessor(s): Kottelat, M.
Reviewer(s): Baird, I. & Brooks, E.
This species occurs in the Sekong basin, southern Lao PDR, and the mainstream Mekong river in northeastern Cambodia and southern Lao PDR. It is found frequently in rapids, stretches of the main river with stone bottom and main tributaries. This species is highly migratory, and it is not known what impact the construction of proposed dams in the Sekong and Mekong drainages would have on population numbers. Many migratory species are significantly negatively impacted by dams, and without further information on the impact for this species, it must be categorised as Data Deficient.

Population [top]


This species is fairly abundant both in the Sekong and Mekong Rivers (Kottelat 2000, Baird et al. 2003). For the Mekong, it is one of the important species caught in the fence filter trap fishery at the Khone Falls (Baird et al. 2003).

Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:

This species was collected in rapids, stretches of the main river with stone bottom and main tributaries (Kottelat 2000). It is known to migrate past the Khone Falls in southern Lao PDR in January-February each year (Baird et al. 2003). It is the only species of the genus known to be highly migratory.

Movement patterns:Full Migrant

Use and Trade [top]

Use and Trade:

This species is utilized as part of local subsistence fisheries (M. Kottelat pers. comm. 2011).

Threats [top]

Major Threat(s):

Part of its range is impacted by the construction of the Xe Kaman dam (Kottelat 2004). Logging, deforestation and agriculture occurs in the area, with associated impacts on the aquatic environment through soil erosion, sedimentation and agricultural pollution expected (M. Kottelat pers. comm. 2011). This species would be impacted by mainstream Mekong dams in northeastern Cambodia and southern Lao PDR and dams planned in the Sekong River basin (Baird and Shoemaker 2008, Baird 2009).

Conservation Actions [top]

Conservation Actions:

Part of the known range of this species occurs in a protected area (M. Kottelat pers. comm. 2011). More information about its life cycle (and in particularly its migratory pattern) is needed.
