    The four papers presented in this publication address major fishery issues in relation to dams as identified by the World Commission on dams (WCD) and FAO for the purpose of WCD? global reviews on ?ams and Development? Characteristics of river and reservoir fisheries in various regions of the world are reviewed. Production figures for reservoirs in Africa, Asia, Latin America and the Caribbean, as well as for the Commonwealth of Independent States, are mentioned . Also fish production figures fo r large rivers are provided, emphasizing the importance of floodplains for fish production. A non-exhaustive review of the current status of the use of fish facilities at dams throughout the world is presented, with the main target species considered from North America, Europe, Latin America, Africa, Australia, New Zealand, Japan and Asia. Fisheries management capacity and information base requirements are reviewed for the six phases of the dam project cycle, i.e. dam identification, dam design, dam project appraisal, dam construction, dam operation and dam decommissioning. Effective environmental assessment and management coupled with improvements in design of civil engineering structures has made some recent dam projects more fish friendly and environmentally acceptable. The need for drafting legal instruments, which will facilitate modification of dam structures to incorporate mitigation measures and help altering dam operation rules to be more beneficial to fish biodiversity and fi sheries, is emphasized.
