Multivariate analysis revealed the presence of 2 distinct assemblages, one belonging to the continental shelf ( 50 m depth). The continental shelf assemblage showed significantly more biomass per tow but not more individuals or species. It is typified by species of interest for the artisanal fishery, like Lutjanus analis and Calamus penna. Lutjanus synagris, however, also of interest for the fishery, typifies the upper slope assemblage. No temporal change was detected in the assemblage structure, at least for the sampling dates in this study, but many species in the assemblages were scarce and rare, indicating high spatial and temporal patchiness. The assemblages found do not fully adjust to existing zonation schemes or assemblages defined in neighboring areas, probably due to the effect of the spatial scale of the studies and the width of the shelf in the Gulf of Salamanca.
