| 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... |

| The advent of remote sensing in biological oceanography in the 1990s offers a very powerful tool able to capture temporal and spatial changes of chlorophyll-a concentration and temperature at several temporal scales (decadal, inter annual and seasonal), and at local as well as at the oceanic scale. Such data have the advantage over traditional measurements of being inexpensive, spatially extensive, automatically repeated in time and validated. They have been very useful for phytoplankton monitoring in relation to eutrophication in coastal waters and the number of applications in the field of coastal zone management is growing. We present here a real case application to shellfish aquaculture. We assessed the potential for mussel aquaculture in Mont Saint... |

| The European flat oyster Ostrea edulis has been considered as the traditional French oyster for a very long time and has now nearly disappeared from our farms, as a consequence of the two successive epizootic of the Marteilia refringens parasite and Bonamia ostreae. The actual quasi monoculture of Crassostrea gigas has made necessary the search for a diversification in oyster culture, including the search for a new start of the indigenous flat oyster culture. The Ifremer has been conducting parallel works since 1985 in order to better understand the biology of the parasite as well as to try and select different lines of flat oyster resistant to Bonamia ostreae. |

| 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,... |

| Un suivi expérimental d'élevage de moules en poches a permis de classer entre elles les différentes stations de l'Aber Wrach, et d'optimiser la charge des poches (4 kg par poche préférable à des charges plus élevées). Cependant, la croissance a cessé à partir du mois de septembre et l'indice de condition s'est dégradé, alors que sur un site voisin ou l'année précédente sur le même site, les résultats d'élevage étaient satisfaisants. Les paramètres d'environnement disponibles laissent penser à un déficit trophique, sans que cette interprétation soit totalement satisfaisante (pousse des huîtres sur le même site). |

| Un concept original de surveillance biologique de la qualité de l'eau a été développé de 1994 à 1998. Les travaux de recherche ont été réalisés en partie dans le cadre de l'étude de l'écosystème de la rade de Brest au sein d'un groupe de travail, sur les indices biologiques, dirigé par l'Université de Bretagne Occidentale (UBO). Une nouvelle génération de valvomètre capable de détecter en temps réel des réactions valvaires anormales et de déclencher un prélèvement automatique d'eau est mis au point. Des enregistrements sont réalisés in-situ sur différents sites pour étudier les réactions valvaires. Des études toxicologiques au laboratoire sont également menées sur la réponse valvaire des bivalves à diverses substances toxiques : métaux et pesticides. Par... |

| 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... |

| For centuries human populations have moved live shellfish around the world for consumption or aquaculture purposes; being relayed from their area of origin for growout or sale. This is in contrast to the inadvertent anthropogenic spreading of species via e.g. ballast waters. There are inherent risks associated with transfer of shellfish including introducing of alien species, diseases, pests, bacteria and viruses associated with the translocated species in addition to the potential impact on genetic integrity and biodiversity of local stocks. Many examples of severe ecological impacts have been documented worldwide owing to the intentional or unintentional translocation of animals. It is therefore important to develop risk reduction methods which have not... |

| 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. |

| 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. |

| A national program started in 1989 to drive researches on Ruditapes philippinarum brown ring disease correlated with a vibrio called P1. The researches have concerned epidemiological surveys on spats and adults, treatment methods, diagnostic techniques, and anatomical and functional studies about the vibrio-clam relations. The transmissions of the disease appeared mainly related to contaminated manila clam seeds, with secondary horizontal propagation. The brown ring formation appeared to be caused by a periostracum deterioration. Taking into account some of these results, an adapted cultural technique including special care of seeds and decreased densities was proposed to the farmers. |
