Résumé(disponible en anglais seulement)
Management of marine finfish aquaculture requires high-quality spatial data to address interactions with local ecosystems, including aspects of both biological communities and ecosystem function. Understanding of the spatial distribution of effects is critical for the implementation of marine spatial planning (MSP), where human activities are spatially managed to ensure sustainable use of resources. Conceptual and technological advances in habitat mapping have greatly increased the availability of marine spatial data, facilitating advances in several areas of aquaculture research.
Multiple case studies will be presented highlighting the use of spatial habitat data for aquaculture research, ranging from local to bay-scale investigations. Particular focus will be given to various methods of spatial data collection, including single-beam acoustics as well as optical data from satellites and UAVs. Mapping data is used alongside oceanographic data and model outputs to scale biogeochemical processes (e.g. benthic nitrogen cycling) in aquaculture areas. Substrate maps are also used to estimate habitat use around aquaculture sites by important wild species such as American lobster (Homarus americanus) and Atlantic salmon (Salmo salar). Spatial data also provide critical information for the management of fish health through epidemiological models of disease and pathogen transmission, crucial for ensuring sustainable aquaculture development in the marine environment. Implications for future MSP efforts in Nova Scotia and Eastern Canada will be discussed along with plans for future research activities in the aquaculture sector.
