Justification:
Channa bleheri is a hill stream species recorded only from the Brahmaputra basin in Arunachal Pradesh and upper Assam with a restricted range of just over 20,000 km2. All hill streams in the region are threatened from decline in quality of habitat due to sedimentation from deforestation and agricultural practices.  In addition, the species is overexploited for the aquarium fish trade and the impacts of proposed dams in the species' habitat is a potential threat, hence the species is assessed as Near Threatened with recommendation to monitor the situation for a future reassessment.
