Fisheries in large tropical reservoirs in South America

The present status of large reservoir fisheries and their management in large reservoirs in South America are reviewed. There is a brief discussion about reservoir typology, and how most of it is inappropriate to fish. Fish in reservoirs and their introduction from other habitats are described, together with comparative yields. The main impacts due to damming are described, including social aspects. Four case studies are presented for the largest reservoirs in South America: Sobradinho, Tucuruí and Itaipu in Brazil, and El Guri in Venezuela.
