| For data-limited stocks (DLS), professional fishing data can be used as a potential source of information, especially in the absence of appropriate scientific survey, to understand abundance evolution under realistic hypothesis on resource catchability. This work focuses on a data-filtering approach, the selected fishing effort must reflect vessel activity that is least dependent on their technical characteristics and as stable as possible over time. The variable of interest is landing by fishing sequence (landing for a given gear, gear mesh, day and ICES statistical rectangle) called LPUE. In order to account for the abundance of the species, it was necessary to consider the discards. The method thus proceeds in 4 steps: (i) focus on LPUE variability and... |

| Marine Protected Areas (MPAs) are generally considered as one of the most important tools, among the many regulations, designed to preserve marine resources as well as enhance fisheries. In the southern Bay of Biscay, local French fishermen requested creation of a restricted area to help settle disputes between the various métiers operating there. This restricted area, which lies mainly in French waters, covers part of a deep submarine canyon off the French and Spanish coasts, known to have a large population of mature hake. This study aims to better understand the effects of a restricted area upon French fleets operating there, particularly upon three main métiers – longliners, gillnetters and trawlers. The study area includes three ICES statistical... |

| Biodiversity conservation and response of benthic communities to pressures, related to global change and human activities, are a research priority. They also constitute a useful indicator to define the environmental status of the Marine Strategy Framework Directive as part of the European Water Framework Directive (WFD). The biogeographic features of the Aquitanian coast (in terms of rocky substrate communities) induce the interest to have a monitoring and research site. Indeed, it includes the habitat characteristics as well as fauna and flora (the Habitats Directive). The aim of the BIGORNO project is to implement new tools to assess the rocky biocenosis in the southern marine subregion of the Bay of Biscay by integrating fauna communities assessment... |

| This report details the results of clam stock assessment survey, which took place between 14 May and 17 June 2018 in Arcachon Bay. Co-organized with CDPMEM33, with financial support from DLAL FEAMP Arcachon Basin Val de l'Eyre, Nouvelle-Aquitaine region, the CDPMEM33 and Ifremer, the clam stock assessment and its characteristics were provided. The samples were collected from 533 sampling stations distributed over an area of 52 km², with an Hamon grab, using a generalized random tessellation stratified spatially balanced design (GRTS). Venerupis philippinarum remains the dominant species with 99 % of the population. The size distribution of Manila clam is in the range 5 – 41 mm with a main mode around 24-28 mm. In 2018, the mean densities are 39 individuals... |

| Certaines masses d’eau s’avérant parfois déclassées par cet élément de qualité, le groupe de travail DCE « Eaux Littorales » a sollicité de la part des scientifiques une réflexion sur les raisons de ce mauvais classement et les éventuelles actions de restauration ou d'amélioration de connaissances relatives aux herbiers de ces zones. L’objectif de cette expertise, soutenue par l’Agence Française pour la Biodiversité, et réalisée en collaboration avec les acteurs concernés par l’indicateur « angiospermes » sur les façades Manche-Atlantique, est d’identifier les pressions potentiellement responsables de cette situation (Tableau 1) en prenant également en compte l’effet des différentes métriques de l’indicateur sur les résultats obtenus. |

| Cystoseira baccata, a biological quality element for the implementation of the Water Framework and Marine Strategy EU Directives, is a dominant species in the subtidal rocky bottoms of the Basque coast. As part of this issue and given the need to better understand the functional character of benthic rocky ecosystems and use them as a reference to anthropogenic changes, two samplings campaigns were conducted in 2014 and 2017. Several population parameters (i.e. frond density, frond length frond-length/total frond-length ratio and taxonomic richness of epibionts) of C. baccata were studied from three sites monitored within the Water Directive Framework in relation to bathymetry during the two campaigns. The results showed a significant influence of... |

| En 2007, le CIDPMEM 64-40 (alors CLPMEM de Bayonne), avait porté une étude sur le poids socio-économique de la filière pêche du quartier maritime de Bayonne. Elle avait permis de décrire le système halieutique local et de quantifier l’impact économique et social de l’activité de pêche sur le territoire par la quantification des flux monétaires entre acteurs et la quantification des emplois générés par l’activité de pêche. Même si les indicateurs définis lors cette précédente étude font toujours référence, le contexte de la filière a très sensiblement évolué en 10 ans et il est apparu indispensable non seulement de mettre à jour les différents indicateurs mais aussi de s'intéresser à des focus particuliers. Le CIDPMEM64-40 a donc à nouveau réuni un ensemble... |
