Résumé :	The ichthyofauna of the Prevost-Arnel lagoonal complex was sampled with a beach seine during three campaigns carried out from February to April 1996. Samples were done at eight stations located at the periphery of the lagoon ecosystem and one station situated in the sea. Ichthyofaunistic data obtained (species richness, density, biomass and mean length of individuals for each species) are distributed along a negative gradient from the sea to the continental shorelines. This distribution is strongly similar to that of other biological compartments, particularly the benthic ones. Thus, the organization of ichthyofauna seems also regulated by the confinement related with the rate of reniewal of marine waters. The sedentary fishes or cyclic migrants can be therefore considered as bioindicators of the biological organization of those paralic ecosystems of lagoonar type.
