| Ce rapport fait la synthèse des travaux réalisés en 2008 et en 2009 au cours du programme Selecmer. Celui-ci, réalisé à l'initiative des professionnels de la pêche en partenariat avec l'Ifremer, avait pour objectif de travailler à améliorer la sélectivité du chalut de fond qu'ils utilisent afin de diminuer les rejets des individus hors-tailles1, en particulier pour le merlan, tout en limitant les pertes commerciales immédiates. Une première phase a consisté à tester l'efficacité de fenêtres à mailles carrées. La deuxième phase a eu pour objectif de développer une grille sélective. Des essais en bassin et des campagnes vidéo en mer ont permis d'apporter des ajustements aux dispositifs sélectifs. L'ensemble des essais de sélectivité à bord des navires de... |

| General introduction: The red mullet is among the fish that are the most popular and that have been known of for the longest amount of time. The Greeks and the Romans have left us in their literature famous pages in which they praise the quality and beautiful colours of their gurnards and their mulles. Also, the skin of this fish has been very popular since earliest antiquity: It is said that for the Romans, a beautiful fish was worth more than the man who had caught it! Moreover, at feasts, a red mullet was displayed in a vase to amuse the guests with the changes of colour (Bloch, 1793). The red rock mullet (Mullus surmuletus) is a benthic fish, which means it lives near the sea bottom. It is geographically present in the Atlantic Ocean from the coasts... |

| The systematic conservation approach is now commonly used for the design of efficient marine protected area (MPA) networks. Identifying these priority areas often involves using specific conservation-planning software. Several of these software programmes have been developed in recent years, each of which differs in the underlying algorithms used. Here, we investigate whether the choice of software influences the location of priority areas by comparing outputs from Marxan and Zonation, two widely used conservation-planning, decision-support tools. Using biological and socio-economic data from the eastern English Channel, we compared their outputs and showed that the two software packages identified similar sets of priority areas, even though the relatively... |

| P>1. The development of ecosystem approaches to environmental management implies the need to account for multiple pressures on ecosystems. Trends in multiple metrics that respond differently to changes in major environmental pressures need to be combined to evaluate the impacts of fishing and environmental changes on fish communities. 2. An exploited fish community is viewed as a three-level food chain in which the two upper levels, or functional groups, are targeted by fishing fleets, while the lowest level is subject to environmental variation. Qualitative modelling is used to predict changes at the two upper levels, that is, top-down vs. bottom-up perturbations. Abundance and length metrics are calculated from survey data for 14 Mediterranean and... |

| The ecological survey n°20 covering PALUEL nuclear power station took place between March and September 1997. The following areas were monitored : Hydrology, microbiology, phytoplankton, zooplankton, intertidal phytobenthos and zoobenthos, and fishing. Paluel power station has now been operationnel for forteen years |

| The scientist community, the fishing organisations and all involved parties show a growing interest in an integrated project management of the sea space exploited by fishing communities. A key to reach such a target is to make available reliable and precise scientist data on the different components of the fishing systems. For about twenty years, and in its mission to support the development of an integrated management for a sustainable use of marine resources, Ifremer has been organising monitoring campaigns of fishery resources along the shores of France. These campaigns aim at providing abundance indicator on species of interest. They consequently provide an essential knowledge base to characterize and trace the status of exploited fish and... |
