| Perkinsosis is one of the most widespread diseases affecting commercially important species of molluscs globally. We examined the impact of Perkinsus spp. on shell growth at the individual scale in 2 clam species: Ruditapes decussatus from Mundaka Estuary (Spain) and R. philippinarum from Arcachon Bay (France). At Arcachon, 2 contrasting sites in terms of environment and Perkinsus olseni presence were chosen: Arguin (disease-free) and Ile aux Oiseaux (infected site). We monitored the dynamics of perkinsosis over the course of the experiment at Mundaka and Ile aux Oiseaux. Prevalences were high (>70%), and intensities were around 10(5) cells g(-1) wet gills at Ile aux Oiseaux, and 10(6) cells g(-1) at Mundaka. No significant differences in prevalence or... |

| Arcachon Bay is the first French field of Manila clam (Ruditapes philippinarum) with an annual production comprised between 500 and 1000 tons in the recent years. In order to improve stock management,an in situ experimentation of chemical marking, using calcein, has been undertaken to validate the periodicity of increment deposition and the optimal conditions of chemical marking in Arcachon Bay. Later on, daily growth rates will be analysed regarding to environmental parameters to increase our knowledge on this species.Manila clam were collected and divided into groups of 80 animals (including control group) which size distribution spread over a large range. Identified groups were marked by immersion in a calcein solution (CAS 1461-15-0), using different... |

| Arcachon Bay, in the southern Bay of Biscay, is the first French production area of Manila clam (Ruditapes philippinarum) with an annual commercial fisheries production around 400 tons in recent years. This bivalve mollusc was introduced into the bay in the 1980s for aquaculture purpose and quickly succeeded in natural settlement so that its high market value led to the progressive establishment of a perennial fishery from the mid-1990s. Local management plans applied to this species are based on a licensing system for the commercial, protected fishery areas and days of prohibited fishing for both commercial and recreational fishermen. A minimum catch size is also prescribed by European regulation, and so growth rates are an important matter in this... |

| Le projet LOUPE a pour objectif général d’acquérir des données complémentaires relatives aux pêcheries à partir d’observations à la mer sur des navires professionnels, avec le recueil de données spatialisées de l’effort de pêche et des captures associées (commerciales et rejets). Ces données sont complétées par un questionnaire socio-économique. Le but est de fournir des indicateurs simples prenant en considération les dimensions écologiques, économiques et sociales pour éclairer les choix des gestionnaires et favoriser la mise en œuvre et l’efficacité de la gouvernance pêche dans cet espace. Le projet propose également de mettre en œuvre un système vidéo fixe et autonome (VECOC) pour réaliser des observations vidéo sous-marines et permettre ainsi... |

| In a context of several directives for transitional and coastal waters masses (Water Framework Directive, Marine Strategy Framework Directive and Bathing Water Directive), the good ecological status of water but also conservation of marine ecosystem should be quickly achieved. The Basque coastline (SE of the Bay of Biscay) is subject to strong human pressures with a high density of population over the year, and especially during the summer with tourist activities. It generates nutrient discharge, water and sediment pollution and impacts the quality of the marine environment. Such pressure and the way to reduce its impacts are the main concerns of authorities Locally, in order to improve wastewater treatment process, an alternative technical solution is... |

| Spatial changes in the dietary regime of Ruditapes philippinarum from intertidal sediments of Arcachon Bay were depicted by analyzing stable isotope ratios in both its adductor muscles and potential trophic sources. Manila clams were collected from 50 sites in May to June 2006. Dietary reconstruction was based on the IsoSource mixing model, considering trophic enrichments of 3.5%. for carbon and 3.0%. for nitrogen, which were determined experimentally. delta C-13 and delta N-15 values, respectively, averaged -28.2 and 5.2 parts per thousand for riverine particulate organic matter (POM), -20.6 and 4.7 parts per thousand for inner bay phytoplankton, -21.0 and 5.6%. for outer bay phytoplankton, -16.8 and 4.8 parts per thousand. for microphytobenthos, -18.4... |

| 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... |

| 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... |

| On imagine souvent les fonds marins proches comme une vaste étendue monotone qui prolonge le littoral, espace de loisir, de découverte et de rêverie. Le recueil d’informations présenté ici sous la forme d’un atlas agrémenté de riches illustrations témoigne du contraire. Le domaine marin côtier du Pays basque et du sud des Landes a fait l’objet de nombreux travaux thématiques sur le milieu physique, le milieu vivant, les ressources halieutiques et les activités qui s’y pratiquent. Un important travail de synthèse a été réalisé par des équipes scientifiques qui, à des degrés divers, se sont investies pour mettre leurs résultats à la portée du plus grand nombre. Elles ont voulu transmettre leurs connaissances mais également leur passion pour cette façade... |

| 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... |

| 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... |

| For species' dynamics highly influenced by environmental conditions, sustainable management for conservation and/or exploitation purposes requires the ability to segregate natural processes from anthropogenic impacts. In this context, identification of phenotypic variations in morphological patterns, and clarification of the mechanisms involved, constitute useful tools to identify adequate management measures from Europe-wide to local conditions. Although such approaches are already used effectively in the management of fish stocks, they are more recent for bivalve stocks, which are also good candidates for such management tools. The current study examines morphological patterns in the Manila clam (Venerupis philippinarum) through morphometric studies of 4... |

| 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... |
