| 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... |

| This report presents a functional typology of the exploitation systems of fisheries in the Charentais sounds. It describes the nature of such a typology as well as the method developed in relation to the topic of the study. The determination and formalization accepted to characterise the exploitation systems are outlined. Also presented is the evaluation of the value of the vessels of the sounds fleet. Types are identified based on two main explanatory variables: capital and work. They enable us to set the internal dynamics of the production system straight. |

| Trois masses d’eau situées sur le littoral de l’île de la Réunion et de la Martinique présentent des fonctionnements et des caractéristiques atypiques, ce qui pose actuellement des difficultés dans le cadre de l’application de la DCE. Les deux masses d’eau réunionnaises, l’étang du Gol et l’étang de Saint-Paul, sont actuellement identifiées en tant que plans d’eau au titre de la DCE. La masse d’eau martiniquaise, l’étang des Salines, est quant à elle identifiée en tant que masse d’eau de transition. L’objectif de cette étude est d’apporter une expertise, sur la base des données disponibles et des échanges avec les experts locaux et nationaux, concernant : · la typologie des masses d’eau, · les paramètres chimiques, physico-chimiques et biologiques... |

| Coastal Mediterranean lagoons are often defined as homogeneous ecosystems that home many migratory and sedentary species. They also host strong salinity gradients, depth variation and very diverse plant communities, which create small-scale heterogeneity within lagoons. This is why each lagoon must be described as an entity by itself made up of a multitude of homogeneous features, called habitats, which support specific ecological functions for organisms (nursery, feeding, protection against predators...). Although many studies have resulted in collecting high numbers of physical, chemical and biological data in coastal Mediterranean lagoons, there is currently a lack of knowledge of the spatial distribution of these habitats. In our project, we (1)... |

| 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... |

| This work aims to describe fishing activity in Guadeloupe through a typology. The samply unit y is the landing represented by a profile of specific composition. Using multivariate analysis methods allows to synthesize this fishing multi specises and multi fishing tackles. Principal Component Analysis and classification regroup landings. Then, segmentation method separateses classes by species composition. Typology is obtained by association of classes and tackles. The contraist between landings of reef fishes realized with traps and those which search for pelagics is clearly shown. Landings of queen conch and landings without fishes are separated in two classes. |
