Schizothorax nepalensis is endemic to the high altitude Lake Rara, Nepal, which is isolated and less than 15 km² in area. The extent of occurrence is the same as the area of occupancy. Although declared a national park and Ramsar Site, there are some threats to the habitat, which negatively impact on habitat quality, hence qualifying for Critically Endangered status for the species, and some authors cite fishing as a threat (e.g. Rai et al. 2002), though this requires further research as the lake is within a protected area and fishing is not permitted.
|Range Description:||Schizothorax nepalensis is endemic to the high altitude Lake Rara in southwestern Nepal at 2,990 m.|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||There is no information available on population of this species. As the lake is facing threats such as exploitation, siltation and pollution, the population is thought to be in decline (e.g. Rai et al. 2002).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It is found in a high mountain freshwater lake.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||Since the lake is within a protected area, no fishing is allowed, but the species is considered a highly-valued food fish and the effectiveness of protection is not known.|
The highly restricted distribution of this species may be threatened by pollution by army personnel and tourists, and minor forest produce collection by locals (Kafle and Savillo 2009). Overgrazing, siltation, pollution and over-exploitations have been reported by many.
Rai et al. (2002) reported the populations are decreasing rapidly due to a heavy fishing pressure, natural calamities, as well as human disturbances such as construction of dams and roads.
|Conservation Actions:||Lake Rara is a national Park (Rara National Park) and is also classified as a Ramsar site. This is one of the efforts to conserve this species in its natural condition. More research in relation to its ecology, habitat management and pollution status in and around its habitat is necessary.|
