| 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... |

| In compliance with the Water Framework Directive (WFD), the good ecological status assessment for Channel-Atlantic coastal water bodies is currently carried out in the intertidal and subtidal zones using a biological indicator based on macroalgae on the rocky coasts. The second step of this Directive (2016-2021) deals with the workings of the marine ecosystem. Therefore, macrofauna has also to be taken into account in the both zones. Current works about the WFD indicator of pressure-impact interactions show deficiencies on how the biological indicators respond to each pressure regarding magnitude and type. Therefore, the implementation of a monitoring program on the southern rocky coast is essential to understand and assess the proper ecological condition... |

| An index CCO (cover, characteristic species, opportunistic species) has been developed for the implementation of the European Water Framework Directory (WFD) in coastal waters, using intertidal macroalgal communities as bio-indicator (Biological Quality Element). CCO is based on the calculation of three metrics corresponding to the global cover of macroalgal communities (metric 1), the number of characteristic species per topographic level/seaweed community (metric 2) and the cover of opportunistic species (metric 3). The final rating is obtained by pooling the scores of the three metrics. Results are given for 32 sites in 29 water bodies, grouped into four biogeographic regions along the Channel–Atlantic coasts of France. Over the six-year study, most of... |

| The rocky Basque coast presents an interest both in terms of biogeography and its patrimonial situation, alongside its habitats, fauna and flora. The aim of the BIGORNO project (Intertidal Biodiversity of the south of the Bay of Biscay and Observation for New research and Monitoring for decision support), financed by the Agency of Marine Protected Areas (AAMP) and the Departmental Council (CD 64), is to respond to significant deficiencies on biocenosis in the southern marine subregion “Bay of Biscay”. Investigations carried out in the WFD, since 2008, constitute an important basis of work for integration of fauna. Field studies undertaken since 2015 consisting of a sampling design suited to the substrates heterogeneity and the presence of microhabitats... |

| This work is based on about 2,000 samples. It provides a synthetic description of the distribution patterns of fûraminiferal assemblages in paralie environments and shows on two examples the effect of anthropogenic impacts. It shows that despite the great diversity of eeological parameters, foraminiferal assemblages are naturally distributeà along a fev/ major gradients. Anomalies in these distribution patterns or morphological abnormalities of the tests indicate anthropogenic or natural stresses. An increase in the number of individuals, specifie richness and test size indicate organic pollution while chemicai pollution as an inverse effect. ln Port-Joinville harbour, Cribroelphidium excavatum and Haynesina gennanica characterize the areas submited to the... |

| L'exploitation des ressources par la pêche professionnelle et par la conchyliculture repose sur des ressources vivantes sauvages ou domestiquées qui sont présentes dans différents milieux aquatiques depuis les rivières jusqu'au large en mer. L'état de ces populations dépend non seulement des choix d'exploitation au regard des capacités de renouvellement des stocks mais aussi des caractéristiques environnementales qui impactent les différentes phases des cycles biologiques des espèces et jouent donc sur leur bon déroulement. Ces conditions du milieu sont tributaires pour partie des activités anthropiques (qualité et quantité d'eau disponible, obstacles au franchissement, autres perturbations) et peuvent être soumises aux effets du changement climatique. Ce... |

| Along biometric characteristics, glass eel otoliths were collected during three migration seasons, in the Adour estuary, during the new moon of January. Microstructure reading and measurements of various growth zones bring information on glass eel larval life during their oceanic migration and the transition phase in estuary. The results show significant inter-annual variations of glass eels otolithometric characteristics from the point of view of their typology as of the various growth zones measured during transoceanic migration. The differences observed between the years on the typology level could be related to very fluctuating environmental conditions during recruitment. The differences in measurements carried out on the registered otolith zones would... |
