Abstract
We use two complementary ecosystem approaches (hierarchical food web and bi omass size spectrum) to analyse the structure and functioning of the Tissaw ewa ecosystem. The effects of water level fluctuations, species interaction s (predation, competition) and species introductions are discussed. The ins ights gained are used to discuss and propose different options for improvin g fisheries management in tropical reservoirs.
