Fish inventory studies are conducted by scientist to examine trends in abundance and population variables for key indicator fish species. The inventory focuses on sections of the River in Laos that are adjacent to dam development near tributaries with development within their watershed. An inventory is also conducted on the Clearwater River to provide some perspective on fish communities of a river without development
