| A spatial sampling was carried out for stock assessment of sea urchin P. lividus throughout the Basque coast. A sampling, over the year, was conducted to study the reproductive cycle. This work took place over 2013 and 2014. Reproduction occurs once in spring, between May and August 2014. Among factors affecting the release of eggs, salinity, temperature and hydrodynamics show a significant inter-annual variability in the Basque coast. Thus, the period set in 2014, may fluctuate between years. For the stock, the results showed that 11.85 (+/-0.32) million individuals of harvestable biomass for 724 tones (+/- 137). Stock is spread over the entire surveyed area density and biomass decrease rapidly with depth, individuals are mainly located between 0 and 5 m.... |

| 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... |

| 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... |

| 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... |

| 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. |

| To determine good ecological status and conservation of the Sub-Marine area of the Bay of Biscay, the implementation of a new rocky intertidal habitats monitoring is needed. A protocol has been adapted from the Brittany protocol for the water body FRFC11 "Basque coast" for the two indicators "intertidal macroalgae" and "subtidal macroalgae" under the Water Framework Directive to qualify the ecological. However no protocol has been validated for fauna in front of meridional characters of the benthic communities. Investigations carried out on macroalgae communities on intertidal area in WFD framework, since 2008, constitute an important working basis. This is the aim of the Bigorno project (Intertidal Biodiversity of the south of the Bay of Biscay and... |

| Introduction: With the objective of diversifying current fishing and at the request of professionals in Aquitaine, the Regional Commission of Maritime Fishing and Marine Breeding (CRPMEM) of Aquitaine has started a discussion about the possibilities of opening a shellfishery. In the context of this course of action, and because of the absence of information on the presence and size of the resource, the CRPMEM of Aquitaine asked IFREMER's Halieutic Resources Laboratory of Aquitaine (LRHA) for assistance in acquiring information on the subject. At the same time, a prospective analysis study of the exploitation of shellfish off the coast of Aquitaineregulation and business sectionwas performed by the CRPMEM of Aquitaine (Coiffec, 2006). At that same time,... |

| Ecological indicators are useful to monitor environmental changes and assess ecological management and conservation. They provide information to understand the environment and its health status while also highlighting changes in the environment by giving early warning signals. Among them, the identification of indicator species add ecological meaning to studied sites and their use is an alternative to sampling the entire biodiversity. The northern Basque coast (located in the South of the Bay of Biscay marine sub-area - France) is dominated by remarkable rocky habitats as stable platforms and mobile boulder fields exposed to swells and freshwater incomes. Recently, the context of the Marine Strategy Framework Directive emphasized significant... |
