| The blue mussel, Mytilus edulis has been reared along the Normandy coast line since the 1960s. The gonadal cycle of this mussel species shows a sharp decrease in meat quality during the winter period after spawning. This decline in meat quality is so severe that sales have to be suspended from December to July. Another species of mussel, Mytilus galloprovincialis, which is reared in the lagoons along the French shore of the Mediterranean Sea has a different spawning cycle. An experiment was undertaken to study the meat quality of M. Galloprovincialis throughout the year after the spat were transferred from the Mediterranean Sea to the Normandy coast. This species showed an immediate adaptation to the gonadal cycle of M. edulis. Despite suggestions from... |

| The blue mussel, Mytilus edulis, is widely distributed in the northern hemisphere, from the White Sea to the Atlantic coast of southern France, and is an economically important species (1 million tons per year, FAO, 2002). At present however, little domestication has been achieved with bivalves, in contrast to agricultural crops, livestock and horticultural species like tomatoes, where selection and production is entirely controlled by man. For bivalves, despite their economic importance, no lines with selected characteristics have been taken to the production scale. There is therefore a need to make up for lost time. Our interest in genetic mapping sprang from some results showing a genetic component to some economically important traits like growth and... |

| A retrospective study has been carried out on the possible relationships between the spat recruitment of mussels from the Pertuis Breton (France) and some environmental factors at different periods of the year. A significant negative correlation between recruitment and temperature has been found at two periods of the reproductive cycle; the first one coinciding with gametogenesis and the second one taking place just before spawning. But, no relation was noticed with temperature or salinity during the plantonic stage. These results are discussed. An interesting relationship was found between recruitment and "E.T.P.", an index expressing the drying power of air, taking into account temperature, wind, sunshine and moistness. Dessication appears to be... |

| We report the construction of the first genetic linkage map in the blue mussel, Mytilus edulis. AFLP markers were used in 86 full-sib progeny from a controlled pair mating, applying a double pseudo-test cross strategy. Thirty-six primer pairs generated 2354 peaks, of which 791 (33.6%) were polymorphic in the mapping family. Among those, 341 segregated through the female parent, 296 through the male parent (type 1:1) and 154 through both parents (type 3:1). Chi-square goodness-of-fit tests revealed that 71% and 73% of type 1:1 and 3:1 markers respectively segregated according to Mendelian inheritance. Sex-specific linkage maps were built with mapmaker 3.0 software. The female framework map consisted of 121 markers ordered into 14 linkage groups, spanning... |

| A Dynamic Energy Budget (DEB) model for simulation of growth and bioenergetics of blue mussels (Mytilus edulis) has been tested in three low seston sites in southern Norway. The observations comprise four datasets from laboratory experiments (physiological and biometrical mussel data) and three datasets from in situ growth experiments (biometrical mussel data). Additional in situ data from commercial farms in southern Norway were used for estimation of biometricalrelationships in the mussels. Three DEB parameters (shape coefficient, half saturation coefficient, and somatic maintenance rate coefficient) were estimated from experimental data, and the estimated parameters were complemented with parameter values from literature to establish a basic parameter... |

| En France, dans les pertuis Charentais plusieurs travaux de recherche ont été réalisés sur la moule (Mytilus edulis) dans les années 80 et 90 (1), (2), (3) 1. Ce n’est qu’en 1999 et 2000 que le programme européen Essence(2) a permis une comparaison entre l'élevage sur filières et l'élevage sur bouchots. Cette comparaison a mis en évidence une différence de croissance en partie liée au temps d'émersion des moules élevées sur bouchot (4), (5). Suite à ces résultats, la profession, représentée par les SRC de Ré Centre Ouest, et la Section Régionale Conchylicole Poitou- Charentes demande à Ifremer de mettre en place un réseau de suivi "biologique" dans les Pertuis Charentais. |

| A 3-year survey was made of several biological markers in mussels (Mytilus edulis) exposed in situ to the oil that came ashore after the wreck of the "Erika" tanker on the Brittany (France) coast in December 1999. The mussel response was assessed using a set of 7 biomarkers, most of them related to the metabolism of organic contaminants. After a series of validation tests, data was evaluated for only 5 biomarkers: acety1cholinesterase (AChE), glutathione S-transferase (GST), catalase (CAT), malondialdehyde (MDA) and deoxyribonucleic acid (DNA) adducts. No significant reductions in GST or CAT levels were observed, levels of DNA adducts and MDA were high during the 6 months immediately following the accident and levels of AChE were significantly lower during... |

| Maintaining the integrity of differentiated genomes in marine organisms needs efficient isolation mechanisms, because planktonic larval dispersion provides contacts between taxa. Habitat specialisation is interesting in this respect, because it can both prevent interspecific crosses (each taxon reproduces in its own habitat) and eliminate hybrids (typically less fit than a parental taxon in each habitat). The contact zone between smooth-shelled mussels Mytilus edulis and M. galloprovincialis in Europe is a good example, as allozyme genotypes typical of both taxa seem to segregate into different habitats. However, allozymes may be selected directly and it is not known whether the same pattern can be extended to the whole genome. Here, we used 6 presumably... |
