Abstract: Although regarded as a 'clean' energetic source, hydroelectric power generated from man-made reservoirs may cause environmental impacts. We provided a review on the ecological effects of large reservoirs to fish and fisheries in the Brazilian Amazon rainforest and in the Lower Tocantins River, as a study case. Fisheries are the main source of animal protein and cash income to Amazon people. Some of the large reservoirs may had affected fish and fisheries down-stream from the dam, due to changes in the flooding regime, retention of nutrients in the reservoir and blockage of fish reproductive migrations. Interviewed fishers mentioned impacts of the Tucuruí reservoir in the Lower Tocantins River, such as decrease in the abundance of fish. Nevertheless, some commercial fishes have been able to cope with the reservoir effects, although the composition of fish catches changed compared to pre-impoundment period. Effects of a large dam may extend beyond the reservoir, and !
fishers have knowledge about their aquatic environments and changes to it. The effects of reservoirs on people and fish should be better acknowledged in political decisions regarding energy issues.
