Abstract:

Sediment transport and siltation influence both the longevity and ecology of tropical reservoirs. The sediment load to these systems is typically seasonal and affects ecological processes at all trophic levels. Fish production is commonly considered a secondary beneficial use of tropical impoundments and in this paper we relate the ecological effects of sediment input to the establishment of a fisheries resource. The need for pre- and post-impoundment environmental monitoring is highlighted and the benefits of establishing a comprehensive watershed management policy are discussed.
