| La recrudescence du ver Polydora dans les coquilles d'huîtres creuses observée dès l'été 1988 a pour principale conséquence le développement parfois très important de formations variqueuses et des chambres à vase à l'intérieur des huîtres, ce qui est très préjudiciable à leur qualité commerciale. Le bilan de l'infestation des coquilles d'huîtres par le ver Polydora sur le littoral normand et atlantique en mai et juin 1989 montre que les secteurs ostréicoles les plus touchés se situent à proximité de la Loire et de la Vilaine. |

| Oyster farming is the main aquaculture activity in France, where Pacific oyster (Crassostrea gigas) is spatially cultured from the English Channel to the Mediterranean coasts. Oyster growth performance monitored along French coasts are widely heterogeneous among culture sites and over years. Many studies have been carried out to understand the effects of environmental factors on oyster growth and physiology, by using bioenergetics growth models. However, most of these studies were site-specific. As an example, the model developed by Barillé et al. (1997), which was extensively specified with more than 50 parameters, was validated in the Marennes-Oléron Bay, but cannot be successfully applied to other culture sites without re-estimating parameters or... |

| An ecosystem-based approach to bivalve aquaculture management is a strategy for the integration of aquaculture within the wider ecosystem, including human aspects, in such a way that it promotes sustainable development, equity, and resilience of ecosystems. Given the linkage between social and ecological systems, marine regulators require an ecosystem-based decision framework that structures and integrates the relationships between these systems and facilitates communication of aquaculture-environment interactions and policy-related developments and decisions. The Drivers-Pressures-State Change-Impact-Response (DPSIR) management framework incorporates the connectivity between human and ecological issues and would permit available performance indicators to... |

| After the decision taken by the French - South African committee to reduce the budget and the duration of all the selected proposaIs of the first call, Rhodes University and Ifremer decided to revise their joint proposaI and organized a meeting in South Africa in february 1998. A multidisciplinary team composed of economists and specialists in different fields of aquaculture spent on week in South Africa (9 and 15 february 1998) with Prof Hecht and his team in Rhodes University, in order to precise the proposaI and define detailed actions to be carried out within the next two years. The present report summarises the principal conclusions of the survey in term of general approach, detailed methodologies and planning for 1998. |

| La situation épidémiologique de la maladie de l'anneau brun et accessoirement les croissances et mortalités observées dans le cadre du réseau de suivi des élevages et gisements naturels de palourdes, en Bretagne, en 1991 sont présentées. En élevage, la situation demeure assez contrastée avec une majorité de semis faiblement infestés (moins de 20 % d'anneaux bruns) et quelques semis fortement atteints, soit en secteurs sensibles (Brouennou, Finistère) soit à la suite de transferts de juvéniles de gisements naturels (Morbihan). Ces gisements naturels sont en majorité contaminés, à des taux faibles (inférieurs à 10 %). |

| The 14th International Conference on Shellfish Restoration (ICSR) comes this year to the United Kingdom for the first time in its 26 years history. The conference will be held at the University of Stirling in the heart of Scotland and its title and theme will be “Shellfish: our undervalued resource”. The theme of the conference, “Shellfish: our undervalued resource”, reflects the UK perception of shellfish as something that is good to eat, often in upmarket restaurants. Shellfish fisheries and aquaculture are indeed a very important part of the UK economy; shellfish reefs however form an ecosystem that provides myriad benefits (“ecosystem services”) many of which have been lost through acute fishing pressures, disease, pollution and other factors. On a... |

| Integration of shellfish farming along the French shoreline (around 5500 km) has been progressive, as marine bivalve culture is a traditional activity in our country. The history of mussel culture relates that the "bouchot" technique (intertidal culture on wooden poles, producing annually around 60,000 tons) was developed as early as the XIIIth century, by a refugee attempting to capture birds by sticking branches of brushwood along the shore. The European flat oyster, Ostrea edulis, already appreciated at the Roman period, was first cultivated in France after Victor Coste introduced the technique of spat collection at the end of the XIXth century. The Pacific cupped oyster, genus Crassostrea, now the most-cultivated in France (around 120,000 tons marketed... |

| Les stratégies d'échantillonnage mises en oeuvre à l 'IFREMER dans le domaine du contrôle de la qualité des produits et du milieu conchylicoles, le long du littoral et dans les installations à terre sont analysées . En outre, les plans d'échantillonnage pour la gestion des cheptels, l'estimation des stocks, de la production biologique, des ventes et des transferts inter-bassins et de l'état zoosanitaire, sont discutés . |

| This study (“Risco”), implicating both industry, socio-economic experts and biologists, was funded by the Regional Council of Brittany, for 3 years (2010-2013), to investigate upon the origin of oysters (Crassostrea gigas) mortalities in the bay of Quiberon (South Brittany, France). Specific mortalities of adult oysters were recorded in this bay in 2006, whereas mortalities of one year old spat were observed since in 2008 in this bay as at a national scale. The experimental protocol in 2010, including a monthly survey of oyster batches at 15 experimental stations, allowed to assess the risk for one-year oysters, due to viral disease. A clear spatial distribution of this risk was evidenced, with a western area spared from contamination and mortality, and a... |
