An Ecopath model of the Sine-Saloum Delta Biosphere Reserve (Senegal)

Abstract : SINE-SALOUM (Senegal), an inverse hyper saline estuary serves as an important resource of fish for local populations. In the last 20 years, annual catches have deereased (from 30,000 to 15,000 t) as has the diversity of species in the catch. Ethmalosa fimbriata, a pelagic Clupeid, is increasingly dominating the estuary and, consequently, the fish landings. Ineffective fisheries management has contributed significantly to these declines while environmental degra-dation threatens the continued functioning of this ecosystem. The Ecopath with Ecosim programme has been used to characterise the current trophic state of the ecosystem and explore ecologically sustainable management .
