| Fish-aggregating devices (FADs) are increasingly used worldwide to enhance tuna catches. Meanwhile, ecosystem-based management of this fishery is constrained by a paucity of information regarding the interaction of FAD-associated tuna aggregations with their local environment. This paper reports the results of a nine-month study around a FAD moored near Martinique Island, aimed at assessing the effects of the local environment on the variability of monthly estimates of proximate tuna biomass. Dual-frequency, active acoustics provided highresolution quantitative data on the pelagic community around the FAD, from fish to micronekton forage. Geostatistics were used to compute biomass estimates of the tuna aggregation comprising most of the FADassociated fish... |

| Spiny lobsters are an important component of the coastal fisheries around the Martinique island. This study aimed to assess the contamination by kepone of the two main species Panulirus argus and P. guttatus in the main fishery area laying along the eastern coast of Martinique. The objectives of the study were to describe the distribution of the spiny lobster contamination in the area, to explore possible relationships with some biological parameters such as individual size, sex and colour of tegument, as well as characterize difference of kepone concentration between the muscle and soft flesh of the head, in view of helping the definition of further fishery management measures. The analyses were done from chemical analyses of 125 samples of spiny lobsters... |

| Moored fish aggregating devices (MFADs) are increasingly being used in small-scale tropical fisheries to access pelagic fish species that are otherwise difficult to harvest in large numbers. Little attention has yet been paid to monitoring MFADs in coastal areas, however. This is most likely due to the small-scale nature of most fisheries that utilize them and the presumed lower impact of those fisheries on fish stocks and their ecosystems. In this paper, we examined the abundance and density of MFADs around Guadeloupe, using aerial line transect surveys. Estimated MFAD densities were found to be high compared with previously reported densities in this area, especially within the 22–45 km range offshore. We examine and discuss possible reasons for these... |

| From April 2003 to April 2004 monthly sea surveys were conducted around 2 fish aggregating devices (FADs) moored at 2000 and 2500 m depth in Martinique (Lesser Antilles). The use of a dual frequency splitbeam echosounder combined with an underwater camera and fishing methods allowed assessment of average space and time distribution of pelagic fish aggregated beneath the FADs, as well as identification of their overall size and species composition. At daytime, 4 fish aggregations were identified at each FAD, representing 4 distinct types: i) an aggregation of small juvenile tuna (mean fork length, FL: 30 cm) observed very close to the surface in 25% of daytime periods; ii) a small surface aggregation dominated by carangids, Caranx crysos, present in 65% of... |

| Small-scale fisheries have traditionally received less research effort than large-scale fisheries and are generally under-studied in Europe. In spite of their comparatively low volume of catches and economic importance, small-scale fisheries are socially important and an integral part of the European coastal zone. Considering the high heterogeneity of situations and the paucity of quantitative data, we used an analytical methodology based on the comparative method. We carried out an analysis of small-scale fisheries (SSFs) in Europe based on a selection of nine case studies. Our objective was to obtain a comprehensive description of small-scale fleets covering different areas/fisheries/species, encompassing the diversity and specific conditions under which... |

| The organochlorine pollution by chlordecone, an insecticide spread in the past in banana plantations, is now recognized as a major ecological, economic, and social crisis in Guadeloupe and Martinique Islands. Due to its physical and chemical properties, this molecule is particularly persistent in the natural environment. Volcanic soil of Guadeloupe and Martinique contain allophanes (amorphous clays), which favor chlordecone trapping due to their structure and physical properties. Thus, with this trapping ability, allophanes serve as a vector allowing chlordecone to contaminate runoff waters and, finally, the sea. In the present publication, several studies recently conducted in the Lesser Antilles have been compiled in order to evaluate the desorption of... |

| The pathogenic virus Panulirus argus virus 1 (PaV1) was first discovered in Caribbean spiny lobsters Panulirus argus from the Florida Keys (USA) in 1999 and has since been reported in Belize, Mexico, and Cuba; its distribution in the wider Caribbean is unknown. We collected tissue samples from adult spiny lobsters from 30 locations in 14 countries bordering the Caribbean Sea and used molecular diagnostics to assay for the presence of PaV1. PaV1 occurred primarily in the northern areas of the Caribbean, where its prevalence was highest. The virus was not found in lobsters from the southeastern Caribbean, and its prevalence was lowest in the southwestern Caribbean. DNA sequence analysis was performed on a fragment of the viral DNA to examine the genetic... |

| Le schéma général de développement du secteur de la pêche en Martinique vise a valoriser de nouveaux secteurs géographiques, il s'agit : - des tombants côtiers (100 à 300m et plus), - de la haute mer (espèces pélagiques), - des bancs du nord de la Guadeloupe, - du plateau guyanais, - à ces domaines pourront s’ajouter les ouvertures sur les autres pays de la Caraïbe grâce à des accords de pêche. Pour cela, les mesures mises en oeuvre ont consisté à promouvoir une pêche au large par la construction de navires de 9 à 11 mètres ("plans-pêche"). Cependant les objectifs fixés n'ont pu être atteints en raison des difficultés successives rencontrées par les plans-pêche pour lesquels plusieurs causes ont été évoquées, portant sur : - le mode de financement de... |

| Blue marlin is fished in the French Antilles around Fish Aggregating Devices (FADs). This fishery commenced in late 1985 and the fishing fleet reached its full potential in the second half of the 2000s. A fisheries information system (SIH), implemented from 2008, enables good estimation of catches and effort around FADs. The data on catch estimates of blue marlin and associated fishing effort are presented herein, as well as the methods used to assess them. From these and a survey of fishing masters, it is possible to reconstitute, year by year, the fishing fleet working around FADs in the French Antilles and to reconstitute a historical series of blue marlin landing. |

| Le projet CHLOHAL comportait deux études. La première portait sur la cartographie de la contamination par la chlordécone des espèces halieutiques autour des îles de la Martinique et de la Guadeloupe ; la seconde avait pour but d'analyser le cheminement de cette contamination dans les réseaux trophiques des écosystèmes côtiers (mangroves, herbiers de Phanérogames marines et récifs coralliens), dans le but d'élucider les mécanismes de transfert de cette pollution vers le milieu marin. L’étude cartographique de la contamination des espèces halieutiques dans les deux îles du projet Chlohal confirme l’image globale de la sensibilité des zones polluées identifiées par les études antérieures. Elle met cependant en évidence des concentrations significatives sur... |

| Chlordecone is a very persistent insecticide used in banana plantations of the French West Indies between 1972 and 1993. Chlordecone residues were found in inland water, in agricultural and freshwater products, and in marine organisms. This pollution has become of great concern in 2007. Therefore, a governmental action Plan was launched to better assess the pollution and to improve the consumer’s protection. Within this plan, 1048 samples from 69 different species of marine fishes and crustaceans were collected all around both the Guadeloupe and the Martinique Islands and analyzed. The results confirm the presence of chlordecone in marine organisms, with highly variable concentrations (from the detection limit to 1000 μg.kg-1). In 17.9 % of the samples,... |
