Different random samplings were used to assess the biomass of intertidal bivalves on two main biotopes of the south west coast of New Caledonia. Over the 46.5 km line of sandy beach, the total bivalve biomass is 4.3 +- 1.8 t and the mean biomass of Atactodea striata is about 3.2 +- 1.2 t. Over the 9.85 km2 sandy-muddy shore of the study area, bivalve stocks (1,050+-392 t) are dominated by Gafrarium tumidum and Anadara scapha; their mean biomasses are respectively 270 +- 132 t and418 + 308 t. This resource is expected to meet the demand of the domestic market through an artisanal fishery
