| An hydrobiological monitoring survey has been carried out in the Bay of Marennes-Oléron since 1977. Five stations, distributed over the Bay, were sam pied twice a month. Spatial and temporal trends of the physical characteristics (i.e., seawater, temperature, salinity, dissolved oxygen and suspended matter), nutrients (azote, nitrite, nitrate, silicate) and organic variables (chlorophyll a and pheopigments) were assessed by using a statistical time-series analysis mode\. It was used to distinguish seasonal variability from long term trends. Pluviometric data as weil as the Charente River fluxes were similary analyzed by the model. The seasonal variability showed an homogeneous pattern over the five stations for all parameters, but the site-dependent... |

| This paper reports a comparative study of two cupped oysters, Crassostrea gigas and C angulata, and their hybrids reared in the Marennes-Oleron Sound (France) under usual farming conditions. The relative proficiency of these species was characterized in terms of growth, survival and reproduction, three major concerns for oyster farming. Four populations of each taxon were sampled (C gigas: Japan and France; C angulata: Taiwan and Spain) and used as progenitors to produce six different progenies under common hatchery and nursery conditions (transfer of 5 to 6 g of seed oysters at sea and rearing in bags for 2 years). Mortality profiles differed greatly among the progenies. The C angulata progeny of Taiwanese origin gave the poorest results, with 100%... |

| La quantité de matière organique et sa valeur énergétique ont été évaluées pour les coquilles de Cerastoderma glaucum, Macoma balthica et Mytilus trossulus de la baie de Gdansk, par extraction chimique et microcalorimétrie. Le contenu moyen en matière organique varie de 0,54% chez C.glaucum, à 5,21 % chez M. balthica et 5,92% chez M. trossulus. La valeur énergétique de la matière organique de la coquille varie entre 15,15 (± 1.41) j .mg-1 chez M. balthica, 20,17 (± 1,60) j.mg-1 chez M. trossulus et 23,88 (± l ,56) j.mg-1 chez C. glaucum. Le contenu en matière organique de la coquille et sa valeur énergétique sont spécifiques, et corrélés avec la microdistribution géographique (facteurs de l'environnement) de la population, ou avec le type de sédiment.

| Le réseau de veille zoosanitaire des mollusques, REPAMO, a été créé en 1992 afin de protéger les espèces d'intérêt économique des maladies susceptibles de les affecter. En effet, de même que les autres productions animales, la conchyliculture est frappée par diverses maladies dont certaines se comportent comme des facteurs limitants de la qualité ou de la quantité des productions. L' histoire de l'ostréiculture française a connu de tristes expériences en la matière, notamment dans les années 70 pour l' huître creuse portugaise, Crassostrea angulata ou encore pour l'huître plate, Ostrea edulis. En fait, nous ne disposons que de très peu de possibilités de protéger les mollusques bivalves vis à vis des maladies infectieuses. D' une part, les traitements,... |

| Many studies based on bioenergetics growth models have investigated the effects of environmental factors on oyster (Crassostrea gigas) growth and physiology. However, most of these models are site-specific and cannot be applied to other culture sites without the re-estimation of parameters or re-formulation of some processes. We aimed to develop a generic growth model suitable for application in contrasting environments, with a constant set of parameters. We tested the oyster-DEB model (Bourlès et al. 2009) for the stimulation of C. gigas growth in different cohorts (spats and adults) at major shellfish culture sites in France, in several years: Arcachon (1993–1994); Marennes-Oléron (2007); Quiberon (1999, 2000, 2001); Rade de Brest (2008); Baie du... |

| Etant donné que la production de mollusques (palourdes ou huîtres) est limitée à 0,8 kg à 1 kg au m2 soit 40 à 50 palourdes adultes de 20 g au m2, il est intéressant d'essayer de forcer cette production en augmentant la production primaire qui est le facteur limitant de la production de palourdes. Cette production primaire dépend des apports en sels nutritifs en effet les travaux antérieurs de Zanette (1979), de Zanette et Garnier (1980), de Robert (1984) ont mis en évidence que les biomasses phytoplanctoniques ne peuvent dépasser un certain seuil à cause de l'épuisement progressif en sels nutritifs. Robert et al. (1984) ont mis en évidence, dans les claires de la Baie de Bourgneuf que l'azote est le premier facteur limitant de la croissance... |

| Le Bassin de Marennes-Oléron représente le premier secteur français de commercialisation d'huîtres creuses C. gigas avec 50 à 60 000 tonnes par an dont 25 à 40 000 tonnes produites localement. Cette différence entre la production et la commercialisation est constituée par les apports d'autres bassins de production, lesquels sont affinés ensuite dans les claires de Marennes-Oléron. Environ 3 000 ha de marais salés sont actuellement en exploitation afin de réaliser l'affinage de ces huîtres qui permet la commercialisation du produit sous l'appellation "huîtres de Marennes-Oléron". Cette marque collective, propriété de la structure professionnelle qu'est la Section Régionale de la Conchyliculture de Marennes-Oléron, repose sur la définition de la Norme... |

| The summer mortality patterns was studied in 1996 on the Ronce-les-Bains oyster bank (175 ha), located on the southern part of the Bay Marennes-Oleron (Atlantic coastline). Studies on growth, sexual maturation, survival rates and environmental variables were compared at fifteen experimental sites (on- and off-bottom culture). After 7 months, cumulative mortality reached 8-19 and 23-33% for off-bottom and on-bottom culture, respectively which is significantly higher for the latter case. A seasonal mortality trend was noted, with a significant increase related to air temperature greater than 20 degrees C and with a significant pre-spawning glycogen catabolism. Based on soft tissue flesh growth results from both types of culture, several empirical models were... |

| Après le naufrage de l'Erika, la question s'est rapidement posée de l'impact des hydrocarbures sur la santé des coquillages, car la pollution concernait des zones de production conchylicoles. Le suivi zoosanitaire en place dans ces zones permettait d'avoir des données de référence avant impact. Il a été choisi différents sites exposés de référence, qui ont fait l'objet d'analyse en toxicologie et en pathologie. A la différence du cas de l'Arnoco Cadiz, l'effort n'a pas été mis uniquement sur les huîtres mais aussi sur d'autres espèces de coquillages, comme les moules et des fouisseurs, particulièrement exposés comme les coques et les palourdes. La mesure de l'exposition effectuée par la Direction de l'Environnement Littoral (MONERlKA) montre qu'une... |

| Le Bassin ostréicole de Marennes-Oléron, et globalement la Charente-Maritime, sont marqués depuis les années 80 (Héral, 1986), par un net recul des rendements de production qui engendrent une diminution de la rentabilité économique et un accroissement des coûts de production. La démonstration de la surcharge biologique du Bassin de Marennes-Oléron est faite depuis 1985. Cette situation a évolué depuis cette date, par une diminution des cheptels en élevage et par une augmentation des cheptels sauvages ce qui a abouti à des plans d'entretien et de restructuration du DPM. Cependant, la situation défavorable pour la majorité des zones charentaises en terme de croissance-production est annuellement confirmée, depuis 1993 au moyen des réseaux de croissance... |

| The Pacific oyster Crassostrea gigas: from an introduced species for aquaculture to an invasive species for the ecosystem Miossec L. and Goulletquer Ph. The Pacific oyster Crassostrea gigas has been introduced worldwide for aquaculture purposes since the beginning of the last century. In most of the countries the species established broadly, emphasizing its ability to adapt to a wide range of environmental conditions. In Europe the Pacific oyster was massively introduced in the 1970s especially into France after mass mortalities of the Portuguese oyster Crassostrea angulata affected by a viral disease. Good environmental conditions in some French areas on the Atlantic coast induced successful recruitments in the following years. The population became... |

| Placopecten magellanicus production in Saint Pierre et Miquelon (NW North Atlantic) has been developed through direct seeding of juveniles on leased areas. However, most of the culture occurs in deep water ranging from 30 to 70 meters, which requires a monitoring by video to facilitate the grow-out and survival evaluation. In August 2008, a submersible leaded structure was connected by a video cable to the surface and observation screen was defined through the video, an altimeter and two lasers. The pictures were recorded on board on hard drive and digital video recorder DVCAM, and data were georeferenced by VIDEONAV software. Analysing the video tapes allows to establish a thematic database on the ground structure, presence or absence of seeded and wild... |

| France is presently one of the leading countries in Europe for shellfish production with 152,000 metric tonnes of the Pacific cupped oyster C. gigas, 2,500 tonnes of flat oyster O. edulis, and more than 60,000 tonnes of mussels M. edulis and M. galloprovincialis. Moreover, species like the pearl oyster Pinctada margaritifera in French Polynesia, and on the Atlantic coastline the scallop Pecten maximus and the Manila clam Tapes philippinarum contribute significantly to the overall landings. . Since traditional rearing areas are now almost overloaded, new management practices are currently under review to optimise and develop shellfish culture. Besides the products resulting from genetic research (e.g. triploids, tetraploids and disease resistant strains),... |

| Oyster landings in the Maryland portion of the Chesapeake Bay have declined by more than 50fold since the early part of the century, despite intensive management efforts. The annual shell repletion program is the most critical programmatic element to effect recovery of the ailing Eastern oyster Crassotrea virginica stock and fishery. The overall efficacy of shell repletion management depends primarily on the success of spat settlement on the planted shell, and furthermore on their survival rate. The Operations Research techniques and mathematical programming developed by Rothschild et al. (1991) attempt to maximize spat recruitment to the oyster stock subject to a series of operational constraints. Allocation and timing of shell deployment are the most... |

| A bibliography of over 1,400 papers on reproduction, recruitment, genetic, pathology, basic biology, and the geographic distribution of the Manila clam Tapes philippinarum is compiled to provide a guide to scientists. This review aims to facilitate access and diffusion of scientific works carried out on this species to the international scientific community concerned by Tapes philippinarum. The bibliography includes publications as well as grey literature published around the world since the early century. Moreover, the large synonymy of Tapes philippinarum and the species geographic distribution are reviewed and updated. The species importance is assessed through public fishery landings and aquaculture production per country. The D'v'eral1 worldwide... |
