| 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... |

| Environmental conditions and xenobiotic exposure can be sources of stress to living organisms. Biological markers are measurable indicator of changes which may happen at any biological level and which can be considered an early warning signal of some biological or environmental state or condition. A structured field study was undertaken to investigate the relationship between three biomarker assays and the spatial and temporal variation of each biomarker in samples of Mytilus edulis. The three biomarkers were the neutral red retention assay, micronucleus assay and comet assay, which indicate damage at different cellular/molecular levels. Three sites in Poole Harbour, an area on the South coast of the UK were sampled on six separate occasions at least three... |

| Growth of the mussel, Mytilus edulis, was compared for the first time under three culture regimes, longline located in open sea, pole and on-bottom both situated on an intertidal flat, in the Pertuis Breton, on the Atlantic coastline of France. Mussel sampling was performed on a monthly basis over 1 year while monitoring of hydrobiological parameters was conducted on a biweekly basis. Fluctuation of environmental parameters showed a similar pattern on both sea and shore locations with generally higher concentration levels for the intertidal area compared with the open sea, i.e. 4.07 and 3.17 mg 1(-1) for particulate organic matter, 3.16 and 2 mug 1(-1) for chlorophyll-a, 58.43 and 38.72 mg 1(-1) for inorganic-N, respectively. A clear seasonal growth... |

| The Marennes-Oléron is a well known cupped oyster (Crassostrea gigas) and mussel (Mytilus edulis) reproduction area. Every year, a monitoring of the reproduction of these two species is carried out on behalf of the Regional Shellfish Culture Section of Marennes-Oléron. This monitoring aims to determine the periods of larval emission in order to let the professionals know about the best collection times This study presents the main results obtained in 1999 and compares them with those obtained in 1997 and 1998. The year 1999 showed good results as far as larval emission and development are concerned in both oysters and mussels. The comparison of the three consecutive years shows the disparity of larval evolutions. |

| Ce document s’inscrit dans le cadre de la problématique des mortalités de moules bleues sur les côtes françaises depuis l’hiver 2014. Il a été conçu comme une contribution aux projets Morbleu (projet de recherche) et Mytilobs (observatoire national sur les traits de vie de la moule). D’un point de vu historique, depuis le début du 20ème siècle, le principale « ennemi » de la moule reste la météo et en particulier, les tempêtes. Une seule crise de mortalité, majeure, est survenue en 1960-61 dans le pertuis Breton. Elle résulte d’une interaction entre le parasite mytilicola intestinalis et des conditions drastiques d’élevage sur bouchots dans la baie de l’Aiguillon. L’évaluation des mortalités de moules est difficile du fait des pratiques d’élevage et des... |

| Depuis 2014, des épisodes de mortalité anormale affectent les cheptels mytilicoles tant adultes que juvéniles. Dès l’année 2015, une première année d’étude a été réalisée au travers de l’action MORBLEU (Mortalité des moules Bleues). Elle a été menée dans les Pertuis charentais et la baie de Bourgneuf. Dans ce même contexte, elle a été reconduite en 2016 afin de poursuivre l’analyse des données collectées en 2015, renouveler une campagne d’étude et d’observation in situ, formuler des hypothèses autour de facteurs favorisants ces épisodes de mortalité de moules, développer des essais permettant de tester ces hypothèses dans le futur et produire des lots de moules pour ces essais et pour caractériser le potentiel adaptatif des animaux face aux épisodes de... |

| Blue mussels Mytilus edulis with shell deformations and green pustules containing parasitic algae were collected at 3 coastal sites (Burøy, Norway; Bockholm, Denmark; Goose Green, Falkland Islands). A comparative study, including mussel histopathology, algal morphology, ultrastructure and phylogenetic position was performed. Green pustules were mainly located in the posterior portion of the mantle and gonad tissues and the posterior adductor muscle. Electron microscopy confirmed the presence of algal cells with similar morphology to Coccomyxa parasitica. Algae were oval shaped with a single nucleus and chloroplast, 1 or 2 mitochondria and a dense granular cytoplasm with a lipid inclusion body, Golgi apparatus and small vesicles. Partial small subunit (SSU)... |

| On the contrary to the U. S. where they represent but 4.6% of the total marine production , mollusc, principally bivalves, can no longer be considered as a marginal production. In France, 100 000 ton of oysters, 98% of which is represented by Crassostrea gigas (Héral & al., 1985) and 85 000 ton of mussels (Mytilus edulis, Mytilus edulis galloprovincialis) (Dardignac, 1985) are produced yeraly. Elsewhere, new rearings are being developed, such as pectinidae and Ruditapes philippinarum, on the Atlantic and Mediterranean coasts. The species presently cultured, some of which dependiing only on natural collections (Crassostrea gigas, Mytilus edulis, Mytilus galloprovincialis while others depend on hatchery production, either partially Crasssotrea gigas in... |
