| 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... |

| 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... |

| The implementation of European Directives in the last decade (WFD, MSFD, DHFF) shows a growing interest in assessing the environmental status of coastal areas in maintaining the ecosystems functionality and biodiversity conservation. In this context, investigations on benthic communities were launched to increase knowledge on taxonomic composition and their spatial distribution. On the Basque coast, rocky shores present remarkable habitats and biogeographic specificities, both in intertidal and subtidal areas. These productive environments, covered with shallow seaweed beds, have a high functionality such as nursery and a protective function for many species during their life cycle. At the scale of marine sub-area of the Bay of Biscay, data available... |

| Les informations de ce document sont issues des données de la DPMA (fichier flotte, fiches de pêche et données de ventes) et des données d’enquêtes économiques auprès de navires, dont l’activité annuelle est suivie par le SIH (Système d’Informations Halieutiques contact : emilie.leblond@ifremer.fr site public http://www.ifremer.fr/sih ). Des enquêtes économiques complémentaires ont été réalisées par M. François Gallet de l’Institut des Milieux Aquatiques dans le but de pouvoir restituer, pour le site d’étude, les données socio-économiques. Depuis 2007, ce travail est porté par le Comité Local des Pêches Maritimes et des Élevages Marins de Bayonne et outre l’autofinancement, il a été réalisé avec les concours financiers du Conseil Régional d’Aquitaine et du... |

| In 2008, were recorded for the first time Derichthys serpentinus in the Bay of Biscay, Kyphosus sectator in the Pays basque, Liparis montagui in the Charente-Maritime, Boops boops in Normandy. Some juveniles of Dentex dentex were observed in the bassin d'Arcachon in 2007 and 2008. We indicated also the catches of Tetragonurus cuvieri, Callionymus reticulatus, Seriola rivoliana and Brama brama. |

| Under the WFD monitoring the “subtidal macroalgae” parameter is calculated for the second time on the Basque coast water body from the protocol used in Britain and adapted to local environmental context. In 2011, three stations were sampled instead of 5 in 2008. The result is the same to the one obtained in 2008 with a quality index "medium" for the whole of the water body. The main criterion penalizing the calculation of the index is "opportunistic species" for each station. There is variability between sites according to the criteria between the two campaigns reflecting the interest of monitoring every three years on the three sites. |

| 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... |
