In the Himalayan rivers, the population is rapidly declining through its native range, including some evidence of catastrophic collapse, due to pollution,[3] overfishing, the effects of dam building, climate change and introductions of other mahseer species.

[11] A close look at the giant red-finned mahseer of Himalayan rivers suggests it is adapted to feeding on the bottom.

This may demonstrate that spawning behaviours have been changed, due to a number of possible factors, but dam building is one of the most likely culprits.

[17] Climate change is likely to have a devastating effect on fish species of the Himalayas, due to a combination of increased flows from glacial melt and rising temperatures due to both a generally warmer local climate and the effect of impoundments.

[22] A correct and long-term study of relative species populations will be needed prior to any attempt to recover stocks through artificial breeding.
