Resumo: 	Macrobenthic sampling was carried out during the survey of mussel beds (Mytilus edulis platensis, D'Orb)at the continental shelf of Buenos Aires province (Argentina)(EH-06/93, INIDEP). 47 samples were obtained with a hard bottom dredge between 18 m and 64 m depth;sedimentological samples were also collected in every station. The following descriptors were used: Maxime Dominance, Relative Dominance, Relative Presence (Bouderesque, 1971), Specific Diversity(H')(Shannon   Weaver, 1963)and Evenness (J')(Pielou, 1966)Faunistic associations and areas of distribution were defined usingcluster analysis (UPGMA, Q and R modes)(Legendre   Legendre, 1979).The community structure of the benthic macrofauna associated to mussel beds was defined for a coastal area between 37°S and 39°.These areas are characterized by a high heterogeneity in granulometric composition and patchy distribution of faunistics associations.
