Analyse des flottilles du sud du golfe de Gascogne, de 1986 à 2002 – De Noirmoutier à Bayonne. Description et évolution des composantes de pêche ArchiMer
Leaute, Jean-pierre.
This document presents a comparative assessment of six triennal analysis carried out between 1986 and 2002, 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 (gears used, landed species) and multivariate analysis procedures have been used to produce groupings of vessels. Over the period, 11 components, on average, have been identified, grouped in two entities, mobile and fixed gears. If the discriminative characteristics...

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»....

Analyse typologique de la flottille du Mor-Braz ArchiMer
Gondeaux, E..
The fishing fleet ana lysis and search of classification criteria are required by the inshore fisheries complexity. For the Mor-Braz fishing fleet, boats ordination and structuration are based on analysis of their seasonnal activity on an annual basis. This is to identify fishing entities or types: Used for their descriptive properties, and linked with cluster analysis, ordination methods appeared as to be powerfull tools. As well as typological studies, studies of the fleet dynamic become easier by these methods. Lastly, the proposed typology which indicates a relation between activity type and individual boats location can be used to improve sampling patterns.

Caractéristiques des petites pêches côtières et estuariennes de la côte atlantique du sud de l'Europe - Rapport final - Synthèse. (24 mars 2000 - 23 avril 2002) ArchiMer
Leaute, Jean-pierre.
The European contract PECOSUDE (Small inshore fisheries of the south of Europe) accepted in 2000 (n° 99/024) for 2 years involves French partners (IFREMER, GEOLITTOMER and CEMAGREF), Spanish (AZTI, UPV and IEO) and Portuguese (IPIMAR). The aim is to assess the inshore and estuarian fisheries from Loire estuary to Portugal in view of the negotiations of the PCP in 2002. Three main aspects are considered in the study: fisheries monitoring (data 1999), socio-economy and marketing (data 1999 or 2000). Three main criteria have been established to define the limits of the fishing fleet considered in the study : fishing grounds within the 12 miles zone for the French fleet and the continental shelf and slope (down to 1000 m depth) for northern Spanish and...

Elaboration d'un protocole d'analyses de données pour une typologie des peuplements démersaux du plateau continental guyanais ArchiMer
Nerini, D..
Two trawl surveys (1 993 may, october) have been conducted by the IFREMER in order to carry out a typology of demersal populations and to map the spatial distribution of the penaeid shrimp Penoeus subtilis (French Guyana shrimp fishery Deet target species) over the French Guyana continental shelf. For this purpose, a particular data analyses procedure was designed. On one hand, inertia and cluster analysis were used to detemline the main structures of dcmersal communities. On the other hand, mapping of Penaeus subtilis distribution, and espccially of the recruits in the fisher)', \Vas obtained through geostatistic technique. Impacts of the Amazon and Guyana ri vers on the demersal ecosystem are strong. They inducc separation between the demersal...

Elaboration d'une technique d'évaluation rapide des stocks conchylicoles à l'usage de la profession ArchiMer
Le Moine, Olivier; Geairon, Philippe; Razet, Daniel.
La connaissance des stocks commercialisables est un atout dans la gestion de la campagne de commercialisation. L'Organisation des Producteurs d'huîtres de Marennes Oléron, consciente des avantages que serait cette connaissance de manière précoce, a donc demandé à l'IFREMER, lors de la contractualisation profession - IFREMER 2001, de mettre au point une technique qui permettrait d'acquérir ces données de façon aussi simple et précise que possible. Les évaluations de stocks conchylicoles sont une des missions que les laboratoires côtiers de l'IFREMER accomplissent de manière périodique, tous les cinq ans à Marennes Oléron. L'année 2001 est celle de l'échantillonnage exhaustif à Marennes Oléron, opérée par le Laboratoire Conchylicole de Poitou-Charentes. Il...

Elements sur les investissements et les couts de production de la petite peche non chalutiere bigoudene ArchiMer
Girard, Sophie.
A classification of non trawling small fishing boats of the Guilvinec port synthesizes a first desc ription study. The characteristics used for this typology are the number of labour and the fishing gear. The analysis of the income and the investment allows for an estimate of the differences in productivity and in capital intensity among the small-scale fisheries. Then, the analysis of a survey on the production costs deals mainly with the remuneration of labour in the artisanal fisheries.

Estimation de la biomasse d'huîtres non cultivées dans le bassin de Marennes-Oléron ArchiMer
Prou, Jean; Pouvreau, Stephane; Renaud, Vivian.
In the Marennes-Oléron oyster culture basin, the cultivated oyster stock shows an unbalanced age distribution: 25 000 to 30 000 tonnes are commercialized each year for a total cultivated biomass of 95 000 tonnes (1993). The biological overexploitation of the basin requires a reduction of the stock in order to get back to productivity rates that are compatible with the restrictions of the oyster market. This study gives an estimated natural deposit biomass of around 3 000 tonnes. An estimate of the abandoned and wild oyster biomass shows that 20 000 tonnes of these animals can be considered as competitors to cultivated oysters. [...].

Estimation of technical interactions due to the competition for resource in a mixed-species fishery, and the typology of fleets and metiers in the English Channel ArchiMer
Ulrich, Clara; Gascuel, Didier; Dunn, Matthew R; Le Gallic, Bertrand; Dintheer, Christian.
In a multi-gear and multi-species artisanal fishery, the level of technical interactions (i.e. the competitive externalities resulting from a shared exploitation of common resources or fishing grounds) among various fishing units is high. Assessing these technical interactions is of great importance for fishery management, as any control applied to one fishing unit may have positive or negative effects on others. The magnitude and direction of these effects cannot be easily measured, unless all fishing units and species in the fishery are considered simultaneously. Technical interactions are particularly important in the complex artisanal fisheries of the English Channel. Using a bioeconomic model of the English Channel that incorporates all the major...

Etude technico-économique sur les DCP côtiers ancrés de La Réunion. Rapport final ArchiMer
Guyomard, David; Hohmann, Sandra; Fleury, Pierre-gildas; Bissery, Claire.
Reconnus dans toute la zone intertropicale comme outils d'aménagement incontournables des petites pêches côtières, les DCP (Dispositifs de Concentration de Poissons) ont été implantés autour de La Réunion à partir de 1988 et gérés collectivement par le Comité Régional des Pêches. Ces DCP côtiers, ancrés à quelques milles des ports de pêche ont permis un redéploiement d'une grande partie de l'effort de pêche vers les espèces pélagiques du large, diminuant ainsi la pression exercée sur les espèces récifales côtières. La présente étude a pour objectifs de mettre à jour les connaissances techniques et économiques sur le "système DCP", autour des pêcheurs, de la pêche sur DCP et des DCP eux-mêmes. Une enquête des usages et des perceptions des pêcheurs vis-à-vis...

Etudes des activites de peche dans le golfe du Morbihan, peche professionnelle ArchiMer
Peronnet, Isabelle; Talidec, Catherine; Daures, Fabienne.
The objective of the study is to improve knowledge of coastal fishing activity in the halieutic and economic spheres. It consists of three sections: On-board professional fishing, professional shellfish gathering, and leisure fishing, this last one being the subject of an independent report (Lesueur and Drouot). The methodology applied is based on implementation of specific surveys about the ships that frequented the Gulf of Morbihan in 2001. The emphasis was placed on identifying the occupations practiced in this zone, on describing these activities and their intensity as well as on analysing the economic performance of these fleets. The management methods, regulation of shellfish gathering on listed sites as well as their impacts on the environment are...

La mytiliculture en Hollande et en Espagne ArchiMer
Antona, Martine; Paquotte, Philippe.
This article is the second part of an analysis of mussel-farming sectors in France, Holland and Spain. The first part, devoted to France, addressed the national offering's stresses of adapting to changes in the mussel market. From the viewpoint of questions raised within the profession while preparing the French mussel-farming sector for the regulatory and economic environment of 1992, Spain and Holland offer benchmarks in terms of structuring the offer and planning markets. This article presents the mussel-farming business in Spain and Holland from these two angles.
