Scientists have recorded a rare Himalayan fish species in Tawang, Arunachal Pradesh, marking its first confirmed presence in India.
A team of ichthyologists conducting a biodiversity survey in the high‑altitude streams of Tawang, Arunachal Pradesh, has documented a rare Himalayan fish species, marking the first verified record of the fish inside Indian borders.
The specimen was collected from a tributary feeding the Tawang river during a recent field expedition. Detailed morphological examination followed by DNA barcoding confirmed its identity as a species previously known only from the higher reaches of the Eastern Himalayas in neighboring countries.
The discovery expands the known range of the fish and highlights the ecological importance of the Arunachal river systems, which serve as critical habitats for many endemic aquatic organisms.
Authorities plan to update the national biodiversity database with the new record and are considering habitat‑conservation measures to safeguard the fragile ecosystem where the fish was found.
