A fish ladder is often proposed as a mitigation measure for addressing hydropower project impacts on fish migration. A fish ladder is a structure that enables fish to pass over and across the dam weir to continue their migration upstream. In Nepal, the globally Endangered Golden Mahaseer (Tor putitora) is a long range migratory fish that occurs from the lowlands to about 1000 m elevation in the Himalayas. The presence of hydropower dams on many of Nepal’s rivers blocks this fish species’ migration in many river basins. While much of the biology of this fish is known, it remains unclear whether it has sufficient ability to jump through a fish ladder and if it can, what type of fish ladder would be most appropriate for this species. If a fish ladder is successful, it’s also important to ensure safe downstream fish passage for larvae and fry.
This webinar will feature a panel of experts on fish ladder design and on the Golden Mahaseer to lead participants in what will certainly be a lively discussion of a fish ladder design for this important fish species as well as options for downstream fish passage.
