| L'activité de quatre types d'embarcations (pirogues, barques, baleinières, goelettes) est étudiée à travers l'analyse de l'évolution temporelle entre juillet 1985 et juin 1988 des valeurs de quatre variables : nombre d'unités de pêche actives, nombre total de sorties, nombre moyen de sorties/unité de pêche, durée moyenne d'une sortie. Il ressort de ces analyses de tendance, que l'activité des embarcations impliquées dans la pêche à la ligne à main aux Seychelles s'est considérablement modifiée. Ces transformations doivent être prises en compte dans le cadre d'une éventuelle réorganisation de la flottille. (Résumé d'auteur) |

| Entre le 20 octobre et le 2 novembre 1987, la mission CEPROS de prospection des stocks de crustacés et de poissons profonds sur les accores du plateau seychellois a été réalisée à bord du navire océanographique ALIS de l'ORSTOM. La faune capturée à l'aide de casiers et lignes de fond est décrite. Les rendements des espèces les plus abondantes #Plesionika edwardsi, Heterocarpus ensifer, H. lepidus, H. laevigatus, H. dorsalis, Geryon sp.$ sont analysés en référence à la profondeur de l'échantillonnage, et une approche sommaire de la biologie (croissance, reproduction) de quelques espèces est réalisée.

| The objective of this project was to obtain scientific advice for the purpose of implementing the EUPOA on sharks as regards the facilitation of monitoring fisheries and shark stock assessment on a species-specific level in the high seas. The study was focused on major elasmobranch species caught by both artisanal and industrial large pelagic fisheries on the High Seas of the Atlantic, Indian and Pacific area, which are currently monitored and potentially managed by respective Tuna RFMOs. Estimated “potential” shark species catch in the Indian Ocean is around 160,000 t for 22,000 t. presently declared (7 times higher than declared). Considering all sharks that are not reported at species level, the total amount of shark declared was around 100,000 tons... |

| Depuis le passage de Mayotte comme territoire sous régime communautaire, l’outre-mer français tropical de l’océan Indien ne concerne plus que les îles Eparses qui sont rattachées à l’administration supérieure des Terres Australes et Antarctiques françaises (TAAF). Un parc naturel marin a été créé le 22 février 2012 (décret n°2012-245), il s’agit du PNM des Glorieuses, qui dépend des îles Eparses et s’étend sur l’ensemble de la ZEE des Glorieuses. Les Iles Eparses sont inhabitées et ne disposent pas de flottilles thonières immatriculées à France-Territoires. Néanmoins, les TAAF délivrent des licences de pêche à des palangriers et senneurs français et étrangers souhaitant pêcher dans les eaux françaises, et un programme observateur accompagne l’octroi de ces... |

| Effective ocean management and the conservation of highly migratory species depend on resolving the overlap between animal movements and distributions, and fishing effort. However, this information is lacking at a global scale. Here we show, using a big-data approach that combines satellite-tracked movements of pelagic sharks and global fishing fleets, that 24% of the mean monthly space used by sharks falls under the footprint of pelagic longline fisheries. Space-use hotspots of commercially valuable sharks and of internationally protected species had the highest overlap with longlines (up to 76% and 64%, respectively), and were also associated with significant increases in fishing effort. We conclude that pelagic sharks have limited spatial refuge from... |

| We studied relationships between tropical tunas (albacore (Thunnus alalunga), bigeye (Thunnus obesus), and yellowfin (Thunnus albacares)) and their biotic and abiotic environments through simultaneous acoustic observations of tunas and their prey, experimental longline catch, and oceanographic data in French Polynesia. Vertical habitat limits were estimated based on temperature and dissolved oxygen at capture data. We then studied tuna-micronekton relationships to better understand how tuna occupy the pelagic space, At a regional scale, tunas were more abundant in areas rich in prey with favourable hydrological conditions. Inside such areas, at the scale of a longline set, however, the longline catches were maximal only when prey were not distributed in... |

| Hand-line fishing includes three techniques "long-lines, ledgering" and "drad fishing" used by four types of boat making up the fleet : canoes, open boats, whaling boats and schooners. The result of the following preliminary analyses : non parametric inter specific correlations, species diversity, factorial correspondence analysis, multiple regression, demonstrate the heterogeneity of the behaviour of the boats with respect to the available fish fauna. This heterogeneity results from differences in the fishing radius between boats and the species selectivity of each technique. The species composition of the catch in terms of volume is characteristic for each technique and boat type. (Résumé d'auteur) |

| The scope of the European Union Plan of Action for Sharks covers directed commercial, by-catch commercial, directed recreational, and by-catch recreational fishing of any chondrichthyans within European Union waters. It also includes any fisheries covered by current and potential agreements and partnerships between the European Union and third countries, as well as fisheries in the high seas and fisheries covered by RFMOs managing or issuing non-binding recommendations outside European Union waters. Scientific advice for the purpose of the management of shark species in the high seas is carried out mainly via the Scientific Committees of the relevant Regional Fisheries Management Organisations (RFMO), as well as through specific projects by national... |

| In 2018, a total of 14 French vessels operated in the eastern Indian Ocean including 12 purse seiners and 2 supplies. The total capacity weighted by the months of activity for each vessel is 11686t. The total nominal effort in 2018 was of 2885 fishing days and 2723 sets with 2463 sets on floating objects and 260 on free schools. In 2018, the percentage of sets on FOB was 90% and the catches reached 91%. The total catch of the French component of the EU purse seine fleet of the Indian Ocean was 84,729 t, being composed of 36%, 58%, and 6% of yellowfin tuna, skipjack tuna, and bigeye tuna respectively. Thus, the most noticeable change in 2018 is the shift of catches from the free school sets, dominated by yellowfin, to the associated school sets, dominated... |
