Pethia yuensis has a restricted range of less than 7,000 km² and is known only from two locations in Manipur, in north eastern India. The species is under threat in one location from urban development, while threats to hill stream fishes from habitat quality decline is another threat. It is therefore assessed as Vulnerable with a recommendation that more surveys are conducted to understand the distribution and the populations are monitored.

Previously published Red List assessments:
2010 Vulnerable (VU)

Major Threat(s):

Lokchao River, the type locality of the species has several disturbances due to anthropogenic activities. The river flows near Moreh town, which is an active centre for international trade between India and Myanmar. The species is threatened from decline in habitat quality in due to sedimentation from deforestation and agricultural practices around hill streams.

Conservation Actions [top]

Conservation Actions:

Detailed research into distribution, biology, population, habitat trends, threats and impacts are needed.
