| Cet atlas interactif de la pêcherie palangrière de l'océan Indien a été réalisé dans la suite du projet IOSSSESPADON. Il synthétise d’une part, l'historique de la pêche palangrière de l'océan Indien depuis les années 1950 (efforts de pêche et captures d'espadon – Xiphias gladius par période de 5 ans et par rectangle statistique de 5°) et d’autre part, l'évolution de l'activité de la flottille palangrière réunionnaise depuis 1994 (efforts de pêche, captures et rendements pour les principales espèces ciblées). Pour le volet relatif à la Réunion, les données sont présentées : 1- annuellement par rectangle statistique de 5° (1994 – 2014), 2- annuellement ou par trimestre par rectangle statistique de 1° -2006 – 2014). Cet outil interactif permet une... |

| In the context of the wine industry, we investigate producers' choice between geographical indications and brand advertising to convey information to consumers. Producers also decide whether or not to select an effort level for improving the quality of their products. We show that if this effort level is selected, a producer will prefer to rely on brand advertising for promoting its products and setting up its own reputation. Despite allowing the cost of promotion to be shared, a geographical indication does not sufficiently reward the effort to improve quality. Finally, the selection of both instruments by producers is examined. |

| Single-species management is a cause of discarding in mixed fisheries, because individual management objectives may not be consistent with each other and the species are caught simultaneously in relatively unselective fishing operations. As such, the total allowable catch (TAC) of one species may be exhausted before the TAC of another, leading to catches of valuable fish that cannot be landed legally. This important issue is, however, usually not quantified and not accounted for in traditional management advice. A simple approach using traditional catch and effort information was developed, estimating catch potentials for distinct fleets (groups of vessels) and metiers (type of activity), and hence quantifying the risks of over-and underquota utilization... |

| It is often necessary to sub-sample plankton samples even if the precision of the estimation is thereby decreased. A methodological optimization is looked for. The variance depends on the procedure of construction of the aliquot (strategy) and the number of individuals counted (effort). The sub-sampling effort is allocated in a general context of repartition of the total effort between sampling and sub-sampling. This effort depends on the time consumed by the sub-sampling procedure, the volume of the aliquot and the number of individuals counted. For the same effort, a systematic procedure for the construction of sub-samples is more precise than a random one because it travels through the entire sample and is thus less dependent on the spatial distribution... |
