Abstract (EN): Ten species of molluscs were identified in the freshwater tidal area of the River Minho estuary. Species richness per site ranged from 1 to 9. Abundance ranged from 230 to 4130 individuals per m(2), with an average of 1412 individuals per m(2). Corbicula fluminea (Muller, 1774) presented the highest density, corresponding to 88.7% of the total specimens gathered, followed by Pisidium amnicum (Muller, 1774) with 5.8%. Biomass ranged from 17.0 to 249.6 g AFDW m(-2), with an average of 99.8 g AFDW m(-2). C. fluminea was the species dominating the total biomass (95.4%), followed by Bithynia tentaculata (Linnaeus, 1758) with 1.6%. A multivariate analysis revealed a community with two distinct groups : one group almost or exclusively represented by C fluminea, and another group with a more diverse assemblage.
