Geographic Range [top]
Range Description: This species is found in the Nam Kading basin, Lao PDR. It may also be present in Nam Ngum basin (Lao PDR), but only juveniles are known from here, which are not suitable for accurate identification (Kottelat 2001). There are specimens from Loei in northeastern Thailand which may or may not be this species.

Population [top]
Population: This species is common in suitable habitat (M. Kottelat pers. comm. 2011).
Current Population Trend: Unknown
Additional data:
? Population severely fragmented: No
Habitat and Ecology [top]
Habitat and Ecology: Found in fast flowing waters and rapids. Small juveniles may be found in quieter stretches with gravel substrate (M. Kottelat, pers. comm., 2011).
Systems: Freshwater
Use and Trade [top]
Use and Trade:
This species is utilized as part of local subsistence fisheries. This species is targeted at spawning sites and may end up in local markets, but not in large quantities (M. Kottelat pers. comm. 2011).
Threats [top]
Major Threat(s):
Anthropogenic modification of river morphology impacts this species by reducing or interrupting fast water flow and flooding its obligate habitat. Logging, deforestation and agriculture occurs in the area, with associated impacts on the aquatic environment expected. Chemical pollution from mining also affects water in this species range. A significant part of this species area of occupancy has been impacted by hydro-power development but pristine habitat remains in Protected Areas (M. Kottelat pers. comm. 2011).
Conservation Actions [top]
Conservation Actions: Parts of this species range occurs within protected areas (especially the Nakai National Biodiversity Conservation Area, which are likely to be effectively managed). As the species travels only short distances to spawning grounds, it is able to complete its life cycle upstream of the areas affected by the dams and reservoirs (M. Kottelat, pers. comm., 2011).
Research into population and habitat trends is required.
