This project aimed to determine whether a fishway could be applied as a technology to rehabilitate degraded floodplain fisheries in the Lower Mekong Basin.

Globally, fishways have been used to provide connectivity at riverine infrastructure which creates fish migration barriers. Fishways are a channel around or through a migration barrier which allow fish to move volitionally. Many designs are available to facilitate fish passage, but applying designs that have been developed for other species can lead to sub-optimal solutions that can limit recovery outcomes. It is important that any fish passage solution is based on the sound knowledge of local species and that design characteristics have been well formulated through scientific investigations.
