| A long-term survey of two mussel populations from two natural mussel beds, Bordj El Kiffan and Boudouaou, was carried out from the end of 1984 to the beginning of 1991. Samples had been also collected from 1978-1979 then from 1992-1993, but only from the first of these. Maximal densities were higher than 10,000 ind. m(-2), due to the spring and summer heavy spatfall. At Bordj El Kiffan, densities of M. galloprovincialis were 50 times more important than those of P. perna. At Boudouaou, the abundance of P. perna was 1.7 times higher than that of M. galloprovincialis. From 1986 to 1988, the mean annual biomass in dry weight of tissue including ash was higher for P. perna at Boudouaou (0.886 kg. m(-2)) than at Bordj El Kiffan (0.486 kg. m(-2)). For M.... |

| The effects of Hg concentrations ranging from 0 (control) to 1024 µg 1-1 upon embryogenesis, survival and growth of Mytilus galloprovincialis mussel larvae were investigated . Embryogenesis was abnormal in 50 % of the individuals at 10µg 1-1. The 48 h LC50 for D-shaped, early umbonate, late umbonate and eyed larvae were 51, 164, 322 and 383 µg 1- 1 respectively. The LC50 was an allometric function of ash-free dry weight with exponent b = 0.60. Larval growth was significantly reduced alter 6 d exposure to 4 µg Hg 1-1 and alter 10 d exposure to 2 µg 1-1. No significant differences in lethal or sublethal sensitivity to Hg were found between M. galloprovincialis and previously studied Crassostrea gigas embryos and larvae. The implications of these findings for... |

| Abstract The genus Mytilus comprises a large number of bivalve mollusk species distributed throughout the world and many of these species are considered invasive. In South America, many introductions of species of this genus have already taken place, including reports of hybridization between them. Now, the occurrence of the Mediterranean mussel Mytilus galloprovincialis is reported for the first time from the Brazilian coast. Several specimens of this mytilid were found in a shellfish growing areas in Florianópolis and Palhoça, Santa Catarina State, Brazil. Morphological analysis of the shells and molecular analysis through sequencing of the cytochrome oxidase subunit 1 (COI) confirmed the taxonomic identification. The species is known for its great... |

| 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... |

| The aim of this study was to evaluate the seasonal variations of six biomarkers on Mytilus galloprovincialis, using comparison with physiological index and chemical contamination levels on two sites of Mediterranean sea. The seasonal variations of acetylcholinesterase (AChE), DNA adducts, benzo(a)pyrene hydroxylase (BPH), heat-shock proteins (HSP), metallothioneins (MT) and multixeniobiotic proteins (MXR) were estimated over a two-year period, on mussels which were sampled in Carteau (original site) and La Fourcade (transplanted organisms). Carteau, an industrial site, presents higher contamination levels (HAP, PCB, heavy metals) than La Fourcade, an urban area. The PAH profiles underline a strong spatio-temporal variability of levels and sources of... |

| Durant sept années, de 1933 à la guerre, j'ai observé dans la région de Concarneau (Finistère) le frai de diverses espèces de Lamellibranches marins, notamment de la moule commune, Mytilus edulis var. galloprovincialis (Lmk). Les travaux sur le frai de la moule sont extrêmement nombreux. Les auteurs qui s'en sont occupés n'ont pas eu, en général, la possibilité d'observer les émissions elle-mêmes. Ils ont dû se contenter d'en induire l'époque soit d'après l'état des glandes génitales, soit en observant la présence de larves dans le plankton, soit, enfin, d'après la possibilité de fécondations artificielles. Or, si utiles que soient des observations de ce genre, elles ne permettent d'atteindre qu'à une probabilité de circonscrire qu'une époque relativement... |

| Marteilia spp. are paramyxean parasites that affect several bivalve species of economic interest, such as Ostrea edulis and Mytilus galloprovincialis. Certain aspects of Marteilia spp., such as their life cycle and host affinity and infection dynamics, still remain unknown. The 'Delta de l'Ebre' constitutes a natural model for the study of the life cycle of the parasite Marteilia, since uninfected mussels and flat oysters immersed in the bays can become infected. This, along with the geographical and ecological characteristics of the bays, make it a very interesting location to study the Marteilia life cycle. Preliminary results concerning marteiliosis, mainly in mussels, such as prevalence dynamics, infectious periods, host affinity and host intermediate... |

| Monitoring coastal contamination of trace metals using bivalve molluscs as quantitative bioindicators is widely used in many international monitoring programs. The bioaccumulation of metal within an organism results from the interaction between physiological (growth, loss of weight, absorption, accumulation), chemical (metal concentration, speciation, bioavailability) and environmental factors (temperature, SPM, chlorophyll). By utilizing the parameters above in this study, it appears that modeling metal dynamics in marine mussels is a reliable tool. The model allows understanding the bioaccumulation process which results from the interactions between biological, chemical and environmental factors. One of the objective of this study was to couple a... |

| The main objective of this project was to develop the tools for the in-depth understanding of mollusc biology and pathology. Such a goal has been reached in other biological systems through the development of molecular biology and cell culture. Indeed, development of a mollusc cell culture system is an essential step to approach many of the problems related to mollusc pathology, in particular to use molecular biology tools to study viral infection of these organisms. No continous cell line is available from bivalves and while cell cultures have been obtained from these organisms they are difficult to develop and labor intensive, survival cultures being maintained only for a few weeks. Our goal has been to study in detail many of the parameters involved in... |
