Key Findings

Both species of fish were discovered from remote areas of country. As Glyptothorax gopii was discovered from Mizoram’s Champai district near India-Myanmar border and Garra simbalbaraensis has been found from Himachal Pradesh’s Sirmour district.

As per the experts, origin or evolution of fishes in Himalayas and north-eastern parts of India is probably the consequence or after-effects of orogenic events or geological movement at various stages in Himalayas’ uplift.
