| This paper introduces a semiqualitative approach to analyse the joint dynamics of fleets and stocks in a multispecies, multifleet fishery. We ask whether changes in fleets affect resource dynamics and whether trends in resource influence fleet dynamics more than external drivers do. External drivers include vessel buyback, fuel price, and fish prices, as well as environmental fluctuations. Resource status is measured by abundance and length metrics; fleet capacity is measured by total horse power, and economic metrics such as profitability and earnings are examined as well. A maximum likelihood approach is used to identify the combined metric trends with the largest support in the data. The approach is applied to the French Bay of Biscay fisheries in... |

| This document presents a survey of the marine-related activities in France, i.e. those of the commercial sector (exploitation of minerai and living resources, manufacturing industries, services) and those of the public sector (Navy, State services, education, safety, marine research). A chapter is devoted to the protection of the coastal and marine environment, and the chapter on tourism gives quantitative data on the impacts of the pollution caused by the Erika oil-tanker. Each activity of the commercial sector is described by key-figures (turnover, value added, employmentl. The description of the non-commercial public sector includes data on costs, including personnel costs. In addition to these figures, qualitative information is given on the recent... |

| Ten years after the start of the European Data Collection Framework the availability of cost indicators for assessing the economic status of fisheries or bio-economic modelling is still deficient. Moreover, economic time series are difficult to maintain due to fishermen weariness and sample coverage is often insufficient. To overcome these problems, the paper builds predictive models per operational cost category (fuel, landing, other variable, fixed, salary and total) for the French Bay of Biscay fleet. The cost models had good fit and stressed the key role of gear and vessel size (length mostly) for explaining fishing costs. They suggested that only a small list of variables was needed to predict costs (days-at-sea, total revenue, vessel age, length and... |

| Le statut de département français fait de l’île de la Martinique une des régions ultra périphériques (RUP) de l’Union européenne. L’activité des navires de pêche qui exploitent sa ZEE s’inscrit dans le cadre de la politique commune des pêches de l’Union européenne, et la gestion des ressources partagées avec d’autres pays s’exerce dans le cadre des organisations internationales de pêche afférentes. Avec 1098 navires de pêche dont 1074 de moins de 10 mètres, la flotte de la Martinique représentait en 2009 16% de la flotte française. L’absence de données halieutiques depuis les évaluations de Gobert en 1989 a été identifiée à de nombreuses reprises comme un élément critique pour le suivi de l’évolution des activités de pêche et des ressources exploitées,... |

| While the majority of small-scale coastal fisheries are found in developing nations, a considerable number exist in developed nations as well. Indeed, small-scale fisheries are strongly represented in all European Union (EU) Member States, 81% and 87% of the EU 25 whole fleet is composed of vessels less than 12 and 15 meters long respectively. In 2000, European regulation established a fisheries data collection framework including economic information requirements in order to provide the scientific basis for the implementation of the Common Fisheries Policy. This paper presents the methodology designed to collect the relevant economic data and characterize the status of the French fleets from an economic perspective. Based on stratified sampling plan... |

| The D3.6 aims to assess the competiveness and sustainability of production systems (PS) for all case studies covered by SUCCESS (Whitefish, Flatfish, Coastal fish and shellfish, Mussels, Salmonids, Seabass & Seabream and Carp). This assessment relies on a number of selected indicators which include indicators of economic performance, economic dependency, social and environmental sustainability indicators. The seven case studies represent a significant part of the EU fisheries and aquaculture production (FAP) as they contributed to 55% of the total EU Seafood production in value (38% in volume) in 2014. Case studies include PS ranging from large production units and/or companies, strongly dependent on inputs availability and extra EU imports (whitefish... |

| The development on the ecosystem-based approach to fisheries implies to improve integrated analysis of fisheries by considering the biological as well as the socio-economic dimensions of the exploitation and thus, an improvement in the knowledge of fleets structure, evolution and activity. Since 2000, Ifremer has been implemented a Fisheries Information System (FIS), a multidisciplinary monitoring network allowing an integrated and comprehensive view of fishery systems including biological, technical, environmental and economical components. The FIS covers all the French fisheries, including the so-often neglected small-scale fisheries. One of the originalities of the FIS lies in the fleet monitoring procedure: a comprehensive collection of annual... |

| Leisure fishing, open to everyone and without a license, is a leisure activity in which many people are interested. Conversely to other harvesting activities such as fresh water fishing and hunting, it has practically not been studied until now (Appéré et Bonnieux, 2002). This study, dedicated to practice of leisure fishing at sea in the Gulf of Morbihan, set itself several objectives: - collect and assemble the available knowledge on regulations and practice of maritime leisure fishing - assess the amount of harvesting of certain recreational types of fishing and the economic impact generated by this activity, - highlight the problems of existing or potential cohabitations among the various users of the space and resources in the Gulf. - develop an... |

| La Baie de Granville représente la première région française et européenne de pêche du buccin. Même si cette ressource génère une activité économique importante à l’échelle de la Normandie avec un volume de 8 800 tonnes, 16.82 millions € en 2014 (source SIH), elle reste néanmoins vulnérable. BESTCLIM a pour objectif de 1) Développer la connaissance du cycle de vie du buccin, 2) Evaluer l’activité de la pêcherie et l’état du stock de buccin en Ouest Cotentin avec des méthodes appropriées, 3) Caractériser les aspects socio-économiques de la pêcherie. L’élévation de la température de l’eau impacte la reproduction du buccin en retardant le déclenchement de la gamétogenèse des mâles. Elle a pour effet de réduire de manière importante l’émission de pontes par... |
