Scallops (Pecten maximus) are dispersed widely in this region of strong tidal flows and varied substrates. However, denser aggregations capable of sustaining dredge fisheries occur regularly only in certain areas characterised by low hydrodynamic bottom stress (<10 dynes/cm super(-2)) and substrates mainly of sand, shell and finer gravels. Fisheries occur irrespective of whether the water column stratifies, develops frontal regions in
summer or remains vertically mixed. Potential larval dispersal pathways and recruitment links between the major exploited aggregations are explored using a shelf seawater flow simulation model (NORSWAP).
