Context: Himalayan Ray-finned Fish Conservation
The Sangno clan of the Nyishi tribe in East Kameng, Arunachal Pradesh, translocated the Endangered Himalayan ray-finned fish to a protected mountain stream.
The aim is to protect it from the Golden Mahseer, the apex predator of Himalayan rivers, and promote community-led freshwater biodiversity conservation.
