The aim of this study was to explore the effects of urbanisation on different attributes of the mussel Mytilus galloprovincialis Lamarck, 1819 in the Northern Portuguese coast: This species is harvested in natural systems as well as cultured on ropes suspended from rafts. Since mussel farming involves the capture of very large amounts of young wild mussels from rocky substrates to supply floating rafts, it is interesting to evaluate if urbanisation shapes the density, percentage of cover, depth of clumps, size-frequency distribution and condition index of M. galloprovincialis. To achieve this, a fully nested hierarchical sampling design was follow. Two conditions (urbanised and non-urbanised) were considered. At each condition, three different rocky shores were selected and two sites per shore were haphazardly chosen for the study of the different mussel attributes. Results pointed out that mussel density was significantly lower at urban shores. In terms of size, the abundance of mussels included in higher size classes was larger at urbanised than at non-urbanised shores. Moreover, percentage of cover, depth of clumps and condition index showed significant variability at different spatial scales.
