Resumo: | The Marine Strategy Framework Directive (MSFD), adopted in June 2008, commits Member States to adopt an ecosystemic approach to manage the marine environment. By this directive, France aims to achieve good environmental status of its marine waters by 2020. Descriptor 3 stipulates that populations of all commercially exploited fish and shellfish are within safe biological limits, exhibiting a population age and size distribution that is indicative of a healthy stock. The Marine Directive builds on existing European Union (EU) legislation as the Common Fisheries Policy (CFP) and criteria describing stocks status are derived from international authorities works as the International Council for the Exploration of the Sea (ICES), the General Fisheries Commission for the Mediterranean (GFCM) or the International Commission for the Conservation of Atlantic Tunas (ICCAT). The fisheries sector in France is present in the four subregions, but also beyond. It has the particularity of being highly diversified by all the métiers practiced and all area where fishing activity takes place. Exploited marine living resources are therefore diversified and the main species caught by French vessels are tuna, hake Merluccius merluccius, herring Clupea harengus, King scallop Pecten maximus or anglerfish Lophius spp. Fisheries management aims to ensure sustainability of fisheries resources and of the activities depending on them by applying the principle of Maximum of Sustainable Yield (MSY). Scientific authorities assess stock status with two indicators: fishing mortality (corresponding to the criteria D3C1) and spawning stock biomass (corresponding to the criteria D3C2), from which they produce recommendations for management. As part of the MSFD assessment, it is impossible and unrelevant to adjudicate on a global ecological status of the different marine subregions (from the point of view of the D3 criteria). Indeed, advices of regional fisheries organisations (e.g. ICES, GFCM, ICCAT) conclude that stocks are improving on the one hand and others are deteriorating on the other hand, without delivering a global advice. In 2015, in French metropolitan waters, 122 stocks of fishery resources have a scientific monitoring, including 33 stocks with quantitative assessment and associated threshold values, only 27 % of stocks. Twelve stocks are considered in good environmental status, such as saithe Pollachius virens of the North Sea (marine subregion “English Channel – North Sea”), common sole Solea solea of the western English Channel (marine subregion “Celtic Seas”) or the northern stock of hake Merluccius merluccius (marine subregions of the Atlantic coast). Twenty stocks with quantitative assessment do not achieve good environmental status, such as anchovy Engraulis encrasicolus of the Gulf of Lions (marine subregion “Western Mediterranea”), seabass Dicentrarchus labrax of Celtic Sea, English Channel and southern North Sea (marine subregions “Celtic Seas” and “English Channel – North Sea”), or albacore Thunnus alalunga of North Atlantic (marine subregions of the Atlantic coast).
