A fleet-metier based approach of the small scale fishing activity in the French West Indies ArchiMer
Guyader, Olivier; Reynal, Lionel; Demaneche, Sebastien; Berthou, Patrick; Daures, Fabienne.
The development of the ecosystemic approach for fisheries supposes to improve integrated analysis of fisheries by considering the biological as well as the socio-economic dimensions of the exploitation. A prerequisite for integrated analysis is the improvement in the knowledge of fleets structure, fleet evolution and allocation of fishing effort in the different fisheries. However, small scale fisheries are often characterized by a lack of knowledge on the vessel fishing activity. This paper first presents a data collection methodology recently applied in the French West (Guadeloupe and Martinique) for the follow up of the whole vessel population. Based on a statistical analysis of these data sets, the paper develops a fleet-metier matrix giving the...

Analyse typologique de la flottille chalutière du golfe de Gabès, Sud-Est de Tunisie OceanDocs
El Abed, A.; Jabeur, Ch.; Missaoui, H.; Gobert, R.; Jarboui, O..
Le golfe de Gabès est une pêcherie plurispécifique exploitée par plusieurs engins de pêche. Environ 75 % des chalutiers du pays opèrent dans cette zone. Les apports de la pêche au chalut (chalut de fond type crevettier et chalut de fond type méditerranéen) sont très diversifiés. Une analyse multivariée (Analyse en Composante Principale ACP suivie d'une classification ascendante hiérarchique) réalisée sur les captures des marées des chalutiers travaillant dans cette région a permis d'identifier onze (11) types d'activités: deux métiers pour les crustacés, deux métiers pour les céphalopodes, trois métiers pour la pêche des poissons, deux métiers regroupant la crevette, la seiche et les poissons et finalement deux métiers péchant les «divers»....

Capacity and scale inefficiency: Application of data envelopment analysis in the case of the french seaweed fleet ArchiMer
Guyader, Olivier; Daures, Fabienne.
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.

Etude d'une gestion optimale des pecheries de langoustine et de poissons demerseaux en Mer Celtique. Tome 1 ArchiMer
Charuau, Anatole; Biseau, Alain.
The entire study is divised into three parts : Phase 1 - Collection of data and description of fisheries. Phase 2 - Diagnosis on the exploitation level for the main species. Phase 3 - Fleets analysis and simulation of the exploitation of the fishery. In addition to the description of the fisheries, in the first part, a very cheap method for the study of discards is described for all species and all fleets, the purpose being to use length cohorts analysis according to the JONES'method (1981). Preliminary works on monks, megrim and cuckoo ray are also presented.

Etude préalable à la gestion des stocks de crustacés en Bretagne ArchiMer
Autissier, Isabelle; Coum, Andrée; Cuillandre, Jean Pierre; Veron, Gerard; Latrouite, Daniel.
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,...

Étude prospective de l'exploitation des coquillages au large des côtes d'Aquitaine Volet : Ressources et première approche économique ArchiMer
Caill-milly, Nathalie; Duclercq, Benoit; Morandeau, Gilles; De Casamajor, Marie-noelle.
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 Aquitaine—regulation and business section—was performed by the CRPMEM of Aquitaine (Coiffec, 2006). At that same time,...

Évaluation des rejets sur la pêcherie de langoustine de Mer celtique ArchiMer
Charuau, Anatole.
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 fleet census to sampling schemes: an original collection of data on fishing activity for the assessment of the French fisheries ArchiMer
Berthou, Patrick; Guyader, Olivier; Leblond, Emilie; Demaneche, Sebastien; Daures, Fabienne; Merrien, Claude; Lespagnol, Patrick.
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...

Identification des pecheries cotieres bretonnes et des problemes d'amenagement ArchiMer
Talidec, Catherine; Berthou, Patrick; Rivoalen, Jean-jacques; Bermell, Sylvain; Guillaumont, Brigitte.
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...

La dynamique des pêches côtières du pays bigouden ArchiMer
Charuau, Anatole.
In the beginning, the coastal fleet of the Bigouden region fished by trawling and was completely focused on exploiting lobster and hake. It is a traditional business that expanded between the last war and the 70s, reaching its peak between 1975 and 1980. The best image to give an idea of this fleet is that of a "bucket waterwheel" endlessly discharging its catch in the four ports of the Guilvinec district. Where there is a seafaring business in Guilvinec, Loctudy and Saint-Guénolé, there is a complementarity that is expressed in two ways: - coastal fishing constitutes a very noticeable and regular supplement to production, since sales happen daily and only bad winter weather causes a relative decrease in the supplement. - coastal fishing gives a...

Les pêches artisanales de la Manche Orientale. Flottilles et ressources halieutiques ArchiMer
Lemoine, Michel; Giret, Marc.
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...

L'exploitation des ressources halieutiques dans le Mor Braz ArchiMer
Durand, Jean-louis.
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...
