This project aimed to design and construct an experimental fishway facility near Bangkok, Thailand, and to conduct research at the station. The results could provide basic information for designing fish passes that could be used throughout Southeast Asia. Riverine development projects, including migration barriers, threaten capture fisheries in the Lower Mekong Basin. Inland fisheries yield 2.8 million tonnes and account for 7% of total region's fisheries contribution. They deliver food security and income for rural households and provide protein and important micro-nutrients.
