AbstractThe importance of incorporating spatial information into the assessment and management of scallop populations has long been recognized. Due to the strong association between scallops and substrate type, scallop distributions can be relatively well represented by seafloor habitat maps. These maps, combined with geospatial fishery data, have tremendous potential to improve our understanding of the spatial patterns and complexities of scallop populations and their dynamics in response to fishing. Further, marine habitat maps provide spatial classification of patterns which can be used to understand ecosystem dynamics and support ecosystem-based fisheries management.
In the Maritimes Region of Atlantic Canada, the majority of commercial scallop fishing areas (SFAs) have been surveyed using multibeam echosounders (MBES). In 2010, a detailed underwater imagery survey was conducted in SFA 29W off south-west Nova Scotia and these data were subsequently modelled with MBES bathymetry, backscatter, and associated metrics to derive both a species-specific habitat map for the sea scallop, Placopecten magellanicus, and a benthoscape map of broad bio-physical characteristics of the seafloor. These habitat maps have subsequently been used to improve the understanding of scallop population dynamics, develop a habitat based population model, set biological reference points for fisheries management that incorporates habitat associations, and evaluate overlap between the fishery and benthic communities; all of which demonstrates the tremendous potential of habitat mapping as a tool for improving fisheries science and management.
