ABSTRACT: This study describes the Atlantic Sea scallop (Placopecten magellanicus) fishery using metrics of biological productivity and fishing activity over a 20 year study period. Distant ports and fishing communities are connected at sea by shared fishing grounds; we describe the extent to which ports in the Northeast United States have utilized similar areas of the ocean in the Atlantic Sea Scallop fishery from 1996-2014. During this time period, spatially delineated regulations have become increasingly important in the scallop fishery. To better understand intra-port competition, we integrate multiple data sources, including: an index of fishing activity overlap among ports; biological data on scallop populations; and the scallop fishery's management history. We used a novel mapping method to improve upon the single reported point, and built a comprehensive, high-resolution dataset of fishing activity for commercial fisheries in the Northeast US. We conclude that regulatory changes in available fishing grounds – and thus in access to exploitable biomass – impact fishing behavior among scallop fishing ports. Competition among ports is sharpened when exploitable biomass is limited due to environmental factors, overfishing, or regulatory closures. This multifaceted approach helps us better understand implications of regulatory as well as environmental change in regional fishing economies
