Trishuli Assessment Tool: A Standardized Field Approach To Aquatic Monitoring

February 2, 2021


Led by the IFC, the Trishuli Assessment Tool was recently developed (2019) by a group of international and Nepalese aquatic scientists to improve fish sampling for Hydropower ESIAs. Information is sparse on fish distributions, migratory patterns and population sizes for Himalayan rivers, and sampling is challenging. The Trishuli Assessment Tool promotes use of the innovative methods of electrofishing and environmental DNA to better detect fish. The Tool also includes specific field methods for target indicator fish species including Snow Trout (asala) and the Golden Mahaser (sahar), as well as macroinvertebrates and periphyton. The Tool is also adapted for other basins in Nepal to encourage a higher standard for aquatic sampling and monitoring throughout Nepal. The Tool will be presented and discussed during this webinar, with the justification and use of each sampling method explained.
