Ecology

Habitat

Indus River Benthopelagic Habitat

This taxon is one of a number of benthopelagic species in the Indus River system. Benthopelagic fish inhabit the water column niche immediately above the bottom, feeding on benthos and zooplankton. Water quality issues in the Indus River habitat have historically been dominated by sediment loading in a watershed which is subject to high natural erosivity, and early disturbance by sedentary agriculture on the floodplains and valleys, which disturbances began in prehistory and continue to the present time. Major tributaries of the Indus rise in the Himalayan Mountains and the Hindu Kush; these influent rivers include the Chenab, Jhelum, Ravi and Sutlej. The Indus mainstem rises on the Tibetan Plateau and flows generally westward.

The Green Revolution has exacerbated water pollution by considerable additions of nitrate to promote crop growth. Other aggravating factors have included increasing amounts of herbicides and pesticides, as pressures to increase crop production expand. Flow of the perennial Indus is dominated by: (a) meltwaters from the Tibetan icefield, the third largest ice sheet formation in the world; (b) snowfall and snowmelt from higher elevation of the watershed; and (c) episodic monsoonal rains that lead to periodic flooding in the Indus River basin.

There are several high trophic level native benthopelagic freshwater fish taxa found in the Indus River system including: the 70 cm scaly osman (Diptychus maculatus), the 30 cm reba (Bangana ariza), the 30 cm Indus snowtrout (Ptychobarbus conirostris), the 30 cm Kunar snowtrout (Schizothorax labiatus), the 35 cm false osman (Schizopygopsis stoliczkai), the 47 cm Chirruh snowtrout (Schizothorax esocinus), and the 40 cm Sattar snowtrout (Schizopyge curvifrons)..

Conservation Actions

Conservation Actions

The species is found in some of the national parks of Nepal, e.g., Koshi Tappu Wildlife Reserve, Chitwan National Park and Karnali National Park. There is a need for improved habitat protection at sites where this species is known to occur. Further survey work is needed to determine whether or not this species is experiencing a decline, or is undergoing natural population fluctuations.
