In rocky intertidal landscapes the community structure is a patchwork of different successional processes. The Stalked barnacle Pollicipes pollicipes lives within this rocky intertidal zone and is harvested as a delicacy along the Asturian coastline. To ensure the sustainability of the fishery, continuous research is necessary. In this study, we analyzed the ecological conditions for the solitary recruitment of cyprid larvae by means of a photo analysis and developed generalized linear regression models to reveal important factors that cue the settlement. Surface contours, and contour building red algae Lithophyllum tortuosum and Corralina elongata, as well as abundance of Mediterranean mussels Mytilus galloprovincialis had significant effects on the larvae settlement. The outcome of this study merely suggests ecological trends that need to be researched more precisely in the future.
