Detritus, fish and men...: The Gironde estuarine trophic structure

Abstract : The Gironde estuary is the biggest estuary in France and one of the largest in Western Europe. It is considered to be relatively unspoilt. From the ichtyologic community`s point of view, the articulation between the lower trophic levels and especially copepods, and fish in the upper part of the trophic pyramid, is essential. As it is necessary to better know the global trophic structure of the estuarine ecosystem as a whole, a modelling approach of the energy flows by inverse analysis was developed using the ECOPATH system. At first, it leads us to assume the system to be mass-balanced at the annual level.
