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... |

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... |

This document present the whiting part of the study Striped red mullet (Mullus surmuletus), whiting (Merlangius merlangus) and pollack (Pollachius pollachius) are three species for which individualization of stocks is advanced by ICES in western Europe for areas including the Bay of Biscay and the areas bordering the Iberian peninsula. Since 2012, ICES has provided recommendations with regards to these stocks. These recommendations are given for two‐year periods and are based on an approach adopted by ICES in 2012 in the case of insufficient data for an analytical evaluation (Data Limited Stocks, DLS). For 2013 and 2014, ICES recommended reducing catches by 20% as a precautionary measure compared to 2009‐2011 for the three stocks. Considering that TACs are... |

Bivalves are important components of benthic marine and freshwater ecosystems throughout the world. One of the most exploited bivalves used for human consumption is manila clam (Venerupis philippinarum). In Arcachon Bay (SW France), commercial fishers and scientists have developed a monitoring survey to estimate clam stocks to assist in implementing a sustainable management strategy. The survey design that is currently used is based on standard stratified random sampling (StRS). The survey has been undertaken every 2 years since 2006. Each survey costs approximately (sic) 50 000, with funding provided by similar to 20% of the commercial fishers. The survey is quite expensive, given that this resource is managed mostly at a regional level. In 2016 for... |

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... |

The sea urchin Paracentrotus lividus is an important exploited resource on the Mediterranean coast and has been the subject of much research. In the Bay of Biscay, the situation is different, as some studies have been conducted on the Spanish Basque coast but few on the French part of that coast. However, the Basque coast offers favourable conditions for the development of this species, and its exploitation could be a source of potential diversification for fishermen, especially in the context of difficulties with some other resources. At the request of the managers of this coastal resource, a study was undertaken on sea urchins to improve knowledge of this stock, particularly about its biological characteristics. In this work, assessment consisted of... |

Descartes 2 propose la mise au point et l'optimisation de protocoles d'échantillonnage qualifiant les biocénoses marines et des ressources halieutiques d'intérêt régional sur deux types de milieux aquitains : la côte basque rocheuse et le bassin d'Arcachon. Tester et définir des méthodes d'échantillonnage fiables, applicables en routine et transférables, requièrent une phase de recherche impliquant des compétences en mathématiques, hydrodynamique, sciences du vivant. Le projet contribuera ainsi, par des actions scientifiques, à l'amélioration des politiques publiques pour la gestion du milieu marin, y compris sur des problématiques transfrontalières. Par ailleurs le projet Descartes 2 vise à contribuer au renforcement durable du partenariat... |

Ce rapport rend compte des résultats acquis entre 2012 et 2017 sur les paramètres hydrologiques et le phytoplancton, dans le cadre des réseaux REPHY et ARCHYD (pour les points du Bassin d’Arcachon), et celui du contrôle de surveillance des masses d'eau du bassin Adour-Garonne qui ne faisaient pas l’objet de suivi avant la mise en oeuvre de la DCE. Ce document contient des résultats concernant les éléments de qualité physicochimique (oxygène dissous pour les deux types de masses d’eau, azote inorganique dissous pour les masses d’eau côtières et les masses d’eau de transition peu turbides, température et transparence pour les masses d’eau côtières exclusivement) selon des méthodes présentées dans l’annexe 1 de ce rapport. Sont également incluses dans ce... |

Ce poster présente les pièces calcifiées utilisées pour estimer l'âge des principales espèces de poissons du sud du golfe de Gascogne. La sclérochronologie, du grec “scleros” = pièces dures, “chronos” = temps, “logos” = étude, est la discipline s’intéressant à la croissance des organismes. Chez les poissons osseux, les estimations d’âge sont réalisées à partir de leurs pièces calcifiées et chaque année, ce sont quelques 35 000 pièces qui sont traitées par l’institut Ifremer. Pour la majorité des espèces, l’otolithe, composant de l’oreille interne, est la pièce calcifiée utilisée. |

The ROMELIGO project included a proposal of abundance indicators for whg-89a stock using professional fishing data. The methodolgy is based on the selection of a sample of representative vessels grouped in a cluster with the same technical characteristics, taking into account their LPUE for specifed period and area. The analysis was conducted on an historical dataset from 2010 to 2015. To be able to update it, a conditional decision tree was used to find rules to assign any new vessels to one of the predefined OTB clusters. Then, the trends of LPUE on the overall period were considered. In recent years, the north shows low levels, but the decrease is not significant over the whole period (Pearson test). For the south, no trend emerges. Professionals... |
