Abstract
Abstract The sea scallop ( Placopecten magellanicus ) fisheries in the United States and Canada have experienced unprecedented rebuilding over the past 15 years. Several factors have led to the successful rebound of these industries, including revised management approaches, investments in improved survey technologies, data-rich stock assessments, favourable environmental conditions and some luck. There is no comprehensive understanding of the stock–recruitment relationship for scallops, which complicates management of the species. Through the use of spatial and temporal management strategies, large recruitment events have been identified and juvenile scallops can be protected until they reach a harvestable size. Identification and protection of such anomalous, large recruitment events in Canada and the United States over the past 15 years have rebuilt the stocks and sustained the fisheries. This chapter describes sea scallop life history, the ecosystem inhabited by sea scallops, the composition of the Canadian and US fishing fleets, sea scallop stock assessments, resource surveys and sea scallop fisheries management.
