Description
During 1993 and 1994, quantitative sampling were realized in Norman Gulf (Western Channel) to estimate molluscs suspension-feeders. Four bivalves are regularly sampled : Spisula ovalis, Tapes rhomboides, Glycymeris glycymeris and Venus verrucosa. For each species, individual age and weight were noticed. The spreading gastropod Crepidula fornicata was also sampled. The resultant biomass and distribution are proposed. These results will contribute to the evaluation of trophic exchanges in boundary layer and to the proposed modeling, in the program PNOC (National Program for Coastal Oceanography).
