| The study undertaken during the 1994-1998 planning contract on the Breton fishing fleet made it possible to underscore the size of the economic activity in regional territorial waters: More than 85% of the ships work there. This space, which is a matter of national sovereignty, is mainly managed at the regional level. To clarify the paths that may need to be taken, it seemed opportune to us to identify spatially the coastal fisheries, as well as the main current problems of planning. The fishing zones were mapped. This work required special surveys of the local fishing committees, because it could not be done from existing fishing statistics. The surveys allowed us to approach the localization of the various trades' fishing zones on maps at 1/50,000, as... |

| If Sea Bass fish farming (Dicentrarchus labrax L.) is currently experiencing an increase in Southern Europe, it is vital, in order to better reflect raising structures, to control its wastes. In order to do so, quantifying this species' wastes is essential to be able to present simple excretion ratios, easily useable by the farmer. Those ratios have been based on nitrogen, phosphorus and carbon masses established on intensive farming and 4 batches belonging to his stock (averaging 24, 5 to 362, 5 g). Each batch was followed up during the course of 1 month and fish farming in its entirety for 2 months. Mass assessments for nitrogen and phosphorus were level ((intrants = extrants) but never precise, contrary to what can be found in bibliography. The main... |

| From Normandy to Belgium bordary, the coastal fishery became during the ten last years a significant social and economic actor, which mostly lives by predominant exploitation of Eastern Channel. Recently discovering a situation of resource overexploitation and a difficult cohabitation between "metiers", these coastal fleets are in the heart of various preoccupations of managment at regional, national and european levels. Since 1985, a coordinated programme (including Boulogne and Ouistreham) allowed to progress in the knowledge of complex fisheries through : improvement of statistics, characterisation of coastal fleets and their activity, asses-ment of the knowledge on the resources.This synthesis describes, for 1987-1988, the quality of the regional... |

| Introduction: Marine organism mortality in the Vilaine bay during July-August 1982, consecutive Dynophysis growth since that date prohibiting shellfish commercialisation, repetitious conflicts among sea professionals are the reflection of a fragile ecosystem and current instability of halieutic resources exploitation in Mor Braz . Becoming aware of this fragility the Ministère de la Mer (Ministry of the Sea) initiated the creation of the Commission Quadripartite (Quadripartite Commission) in charge of the Hydrobiologic Protection and Alieutic Development of the Quiberon-Vilaine bay, bringing together administrative and scientific professionals. Right from the start, among the missions entrusted to the Commission, the will to study the halieutic future of... |

| At the end of the seventies, as fishing abundance (based on Catch Per Unit Effort) in crabs and lobster fishery steadily declined, operating expenses increased, and fishing boats changed strategy (changing metiers, covering larger distance to fishing areas, fishing seasons being extended, ...) professionals and scientists aimed to consider reinforcing management measures. To enlighten and support potential related decisions, the Comité Régional des Pêches et Cultures Marines de Bretagne (Regional Committee for fishing and farming in Brittany), together with the ISTPM (Ifremer since 1984), conducted a survey on the exploited populations and gave a review of the involved Breton fleet. This report shows the results of a survey conducted among fishermen,... |

| This document is the progress report, for the third year, of the research programme "Scenarios for Development of Fishing Activity in the Breton Coastal Strip". Co-financed by the Brittany Region within the framework of the XII State/Regional Planning Contract, this programme teams up scientific partners from IFREMER, ENSAR, and UBO (CEDEM). This report is made up of two parts: - The first part is dedicated to the synthesis of the fisheries of Mor Braz. It was a matter of approaching the whole of Mor Braz with the methodology used for the study of customs, resources and space in the Gulf of Morbihan. Following the presentation of fishing activities, the first results on the economic situation of the fleets are explained. - The second part is a legal and... |

| This 2002 report is the progress report of a study co-financed by the Brittany region and IFREMER within the framework of the XII State-Regional Planning Contract. It follows the 2001 report, which contains a comprehensive description of the Breton fleet in 2000, i.e., all occupations included, as well as its evolution since 1983. The work carried out in 2002 focused on mapping the fishing zones frequented by Brittany's ships as well as on analysing fishing strategies. |

| Introduction: With the objective of diversifying current fishing and at the request of professionals in Aquitaine, the Regional Commission of Maritime Fishing and Marine Breeding (CRPMEM) of Aquitaine has started a discussion about the possibilities of opening a shellfishery. In the context of this course of action, and because of the absence of information on the presence and size of the resource, the CRPMEM of Aquitaine asked IFREMER's Halieutic Resources Laboratory of Aquitaine (LRHA) for assistance in acquiring information on the subject. At the same time, a prospective analysis study of the exploitation of shellfish off the coast of Aquitaineregulation and business sectionwas performed by the CRPMEM of Aquitaine (Coiffec, 2006). At that same time,... |

| Data Envelopment Analysis (DEA) models are applied to the main French seaweed fleet to examine capacity output, capacity utilization, and scale inefficiency. Coastal seaweed vessels target only one output - kelp - with the same gear but with different input level combinations. The fishery is seasonal and subject mainly to input regulations, especially a one trip per day regulation implemented in 1987. The consequence was a decline in total observed output and a fall in capacity output and efficient output. Only the largest vessels and a few small vessels harvesting without this regulatory constraint operate at the optimal scale. The question of a change in regulation, especially a shift to an individual quota system, is raised. |

| This document presents a comparative assessment of four triannual analyses carried out between 1986 and 1995, on 1300 boats, on average, from the 35 ports of Southern Bay of Biscay fishing fleets (from Loire river to Spanish border). Fisheries statistics allow the identification of different fishing practices and fishing boats associated with them within the fleets. In order to allow comparison and analysis of the evolution that has taken place during the study period, the same variables (gear used, landed species) and multivariate analysis procedures have been used to produce groupings of vessels Over the period, an average of 11 components have been identified, grouped in two entities, mobile and fixed gears. If the discriminative characteristics (gears,... |

| 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... |
