As infrastructures ages or new structures are proposed, awareness of the importance of fish passage has gained momentum, most recently in the Lower Mekong River Watershed of South East Asia, composed of five nations; Thailand, Cambodia, Vietnam, Lao PDR and Myanmar. Freshwater fish provide the primary source of protein for more than 60 million residents of the Lower Mekong. Much of this resource derives not from the mainstem of the Mekong River but from thousands of tributaries and far smaller waterbodies that traverse the region. These water bodies are increasingly fragmented by weirs, dikes, dams, road prisms, and associated water management structures, mostly associated with agricultural development and local flood control activities. In a land of tens of thousands of constructed barriers, only an estimated 35 fish passage structures exist across the five nations. As these nations move forward to address the issue of fish passage, sharing international knowledge has never been more important.
