| Long-line fishing has been growing on the island of La Réunion since the beginning of the 1990s. The target species is the swordfish (Xiphias gladius), fished mainly in the tropical waters surrounding the island between longitudes 45 degree E and 60 degree E, and latitudes 17 degree S and 27 degree S. From 1998 to 2000, a finalised research programme enabled the collection of precise data concerning the lines' positions and the parameters of the fishing efforts: 3,602 nettings were thus informed by the catches (in numbers of individuals caught) and 12 descriptive variables of the effort. In parallel with this collection effort, satellite maps that described the ocean's landscape of this region of the Indian Ocean exploited by La Réunion's fisheries were... |

| Un nouveau programme scientifique, a débuté depuis mois de juillet 1998, le « Programme scientifique et technique d'accompagnement au développement de la pêcherie hauturière des grands pélagiques à La Réunion » aussi appelé « programme palangre Réunion » (PPR), sous l'initiative de l'lFREMER en collaboration étroite avec la majorité des armements locaux concernés. Les financements des nouvelles actions proviennent du Fonds Européens de Développement Régional (FEDER), de l'Etat, des Conseils Général et Régional de La Réunion. Ce projet comporte deux grands volets : (i) un volet de suivi des pêches et de recherche finalisée sur les espèces cibles, notamment l'espadon ; (ii) un volet d'appui au développement de la flottille palangrière réunionnaise, mettant... |

| Understanding drivers of trophic partitioning at the community level is an essential prerequisite to the establishment of ecosystem-based management of fisheries. In this study, we identify drivers of trophic partitioning within a community of epipelagic fish and a community of deep-water fishes off Reunion Island. Effects of intrinsic (species identity, etc.) and environmental variables (fishing zone, month) on stomach content composition and stable isotope ratios were tested using regression trees and linear models respectively. Our results demonstrated firstly an independence of both communities, with very few common prey although they occurred in similar localities, and secondly, very different patterns of resources partitioning among each community.... |
