| For data-limited stocks (DLS), professional fishing data can be used as a potential source of information, especially in the absence of appropriate scientific survey, to understand abundance evolution under realistic hypothesis on resource catchability. This work focuses on a data-filtering approach, the selected fishing effort must reflect vessel activity that is least dependent on their technical characteristics and as stable as possible over time. The variable of interest is landing by fishing sequence (landing for a given gear, gear mesh, day and ICES statistical rectangle) called LPUE. In order to account for the abundance of the species, it was necessary to consider the discards. The method thus proceeds in 4 steps: (i) focus on LPUE variability and... |

| The common dentex, Dentex dentex, is a fish species which inhabits marine environments in the Mediterranean and Northeast Atlantic regions. This is an important species from an ecological, economic and conservation perspective, however critical information on its population genetic structure is lacking. Most samples were obtained from the Mediterranean Sea (17 sites) with an emphasis around Corsica (5 sites), plus one Atlantic Ocean site. This provided an opportunity to examine genetic structuring at local and broader scales to provide science based data for the management of fishing stocks in the region. Two mitochondrial regions were examined (D-loop and COI) along with eight microsatellite loci. The COI data was combined with publicly available... |

| 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 1972, France underwent an oyster (Crassostrea angulata) crisis and urgently needed to diversify its aquaculture. Thus, Asari clam (Ruditapes philippinarum) was introduced at that time for aquaculture purpose, concomitantly with the introduction of Pacific oyster (Crassostrea gigas). All Asari clam adults and spat originated from the same area (Puget Sound, WA, USA). After a promising start and the implementation of a national Research & Development program, Asari clam culture rapidly faced a series of concomitant handicaps: firstly, in spite the fact that cultural practices were optimized and locking points addressed, leasing ground availability was limited during the 1980s’ due to certain reluctance from oyster farmers to share their leases and/or... |

| 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... |

| We describe an emerging pathology, brown muscle disease (BMD), which specifically affects the Manila clam Ruditapes philippinarum in Arcachon Bay (France). BMD induces a transformation of the posterior adductor muscle, which becomes infused by conchiolin and calcified, reducing the ability of clams to bury. The disease affects both types of muscular tissue, with striated muscle becoming affected to a higher degree than smooth muscle. Two indices were created to quantify the symptoms: the Muscle Print Index, used for empty and live shells, and the Final Disease Index, utilized for live clams only. Histological sections were made and observed under light microscopy to examine the muscular damage and to investigate a causal agent. Sections revealed an... |
