This literature review provides important background information required to ensure maximum effectiveness of the United Kingdom's Department for International Development (DFID) funded project 'The use of Sluice Gates for Stock Enhancement and Diversification of Livelihoods.' It explains research and knowledge to date on sluice gate/regulator management, different types of sluice gates, key aspects of sluice gate operation, fisheries and water management institutions, and the importance of floodplain fisheries in Bangladesh. Key water management and open water capture fisheries related problems are identified and reviewed thus providing some basis for the necessity of the project. The degradation of environment conditions suitable for floodplain fisheries and the cause of this degradation in floodplain fish habitat and resulting declining fish stocks are explored. The review also highlights measures taken to date by government, donors and non-government organizations (NGOs) for inland fisheries development and management, including floodplain fisheries.
