How Does MMEY Mitigate the Bioeconomic Effects of Climate Change for Mixed Fisheries

摘要: Abstract This paper examines the impact of climate change on bio-economic performance Bay Biscay mixed fisheries and explores capacity alternative management strategies to cope with these impacts. A dynamic multi-species, multi-class, multi-fleet model is developed calibrated using available biological, economic environmental information for French fleets. Fishing data have been collected within European Data Collection Framework. Climate represented by sea surface temperature assumed affect species recruitment. Three are compared in terms outcomes: Status-Quo (SQ), a Multi-species Maximum Sustainable Yield (MMSY) strategy Economic (MMEY) strategy. These ranked respect two contrasted scenarios regarding Representative Concentration Pathways (RCP) driving change. Results show that SQ not sustainable characterized major decline key commercial species. By contrast, MMSY improves ecological state fishery. The MMEY yields even greater improvements. Bio-economic benefits however altered effects Under strategy, fleets more diversified catch structures perform better facing
