Résumé(disponible en anglais seulement)
Ecosystem Approaches to Fisheries (EAF) are seen as essential for sustaining fish stocks and fisheries over the long-term, and require the integration of ecosystem components, typically through multivariate and multifunction analyses. Large scale functional maps showing the distribution of organisms with particular biological traits (e.g., deposit feeders, filter feeders, biogenic engineers, carbon sequesters, etc.) can provide a detailed spatial framework for incorporating benthic ecosystem function into an ecosystem services framework.
Building on this experience, here we propose that combining biological traits analyses (BTA) with seabed mapping can be used to identify areas according to dominant ecological function, which can provide a detailed spatial framework for considering ecosystem services within the overall EAF. Furthermore, identification of the environmental determinants for each function could allow evaluating responses of the function to fishing and future climate change.
Based on the epibenthic invertebrate fauna from a bottom trawl research survey targeting groundfish in the Flemish Cap area (northwest Atlantic), functional maps with particular biological traits have been elaborated. The different ecological functions or ecosystem services represented on these maps can be used, for example, to identify areas where biogenic process could represent an important regulator and driver of overall benthic productivity versus areas where physical factors may be more relevant for driving overall benthic production or they can help to identify areas where ecosystem changes may have happened. These types of maps can be incorporated into the Northwest Atlantic Fisheries Organization (NAFO) Roadmap as part of the assessment of ecosystem sustainability to achieve an EAF.
