| This study aimed to assess the ecotoxicological effects of the interaction of fullerene (C60) and benzo[a]pyrene (B[a]P) on the marine mussel, Mytilus galloprovincialis. The uptake of nC60, B[a]P and mixtures of nC60 and B[a]P into tissues was confirmed by GC-MS, LC-HRMS and ICP-MS. Biomarkers of DNA damage as well as proteomics analysis were applied to unravel the toxic effect of B[a]P and C60. Antagonistic responses were observed at the genotoxic and proteomic level. Differentially expressed proteins (DEPs) were only identified in the B[a]P single exposure and the B[a]P mixture exposure groups containing 1 mg/L of C60, the majority of which were down-regulated (~52%). No DEPs were identified at any of the concentrations of nC60 (p < 0.05, 1% FDR).... |

| Studies were carried out to investigate the contamination of Piracicaba and Mogi-Guaçu River basins (São Paulo State, Southeastern, Brazil) for heavy metals (Cd and Pb), using the limnic bivalve Anodontites trapesialis as a biological monitor. The results showed that the concentrations of Pb were higher than the control group in both basins, showing the bioavailability of this non-essential element in the basins. The concentrations were higher in the Mogi-Guaçu than in the Piracicaba basin, and in the slightly contaminated sites in both basins. There was no correlation between the degree of human impact and Cd and Pb concentrations, it was not possible to infer about concentrations of these heavy metals in the bivalves based only in a broad evaluation of... |

| Water samples were collected around the communities of a hydrothermal mussel, Bathymodiolus sp., in the Lucky Strike (1700 m depth) and Menez Gwen (850 m depth) areas, Mid Atlantic Ridge, and analysed for chemical constituents. The environment surrounding the organisms consists in sea water (88 to 100%) mixed with hydrothermal fluid with pH between 6.2 and 8, Sigma S (H2S + HS-) concentrations from 0 to 62 mu mol l(-1). High dissolved organic carbon (DOC) concentrations suggest a highly productive ecosystem. Production of ammonium and DOG, consumption of nitrate and sulfide in the vicinity of the organisms are among the environmental changes found in relation with local biological activity. Concentrations of Cu and Pb were high, implying that the organisms... |

| This study examined the influence of increasing temperatures in spring and summer on biochemical biomarkers in Mytilus galloprovincialis mussels sampled from Bizerte lagoon (northern Tunisia). Spatial and seasonal variations in a battery of seven biomarkers were analyzed in relation to environmental parameters (temperature, salinity and pH), physiological status (condition and gonad indexes), stress on stress (SoS) and chemical contaminant levels (heavy metals, PAHs and PCBs) in digestive glands. Integrated Biological Response (IBR) was calculated using seven biomarkers (AChE, BPH, MXR, GST, CAT, MDA and MT). Seasonal variations in biological response were determined during a critical period between spring and summer at two sites, where chemical... |

| Mass mortality outbreaks (90-100%) in both juvenile and adult blue mussels were reported in 2014 along the Pertuis Charentais area of the French Atlantic coast. A series of studies were carried out to learn more about the phenomenon through detecting pathogens, describing environmental conditions and establishing the physiological status of the animals. Bacteria identif ied as belonging to the V. splendidus species were detected in dying mussels and seem able to cause mortality in blue mussels in the laboratory. Unusual environmental conditions (large amounts of fresh water, re-suspension of sediments during a series of storms, and a high renewal rate of specific water masses in Brittany’s Pertuis area) may be partially responsible for sparking the phenomen |

| The quantity of mussels cultivated on wooden poles called « bouchots », in Mont Saint-Michel bay, has been estimated in april 2002, by volume, number and weight. To do so, a sampling strategy has been conceived, operated and then optimized, taking into account the spatial distribution of this stock and the material and human constraints (especially the amount of persons and working days available). The sampling plan uses procedures of stratification, degrees, regression, so as to reach the optimum precision related to cost. The operation took a great advantage of the efficient help of mussel farmers. During the first day, the task consisted to estimate the number and position of poles occupied by mussels, with the help of 5 persons on boat. The following 2... |

| This study compares the prevalence and abundance of the isopod Edotia doellojuradoi in the mussel Mytilus edulis, between water column rope farming systems and nearby natural benthic beds at Puerto Raúl Marín Balmaceda (43° 46' S, 72° 57' W), Aysén, Chile, taking into account the maximum shell length of the host as a covariate. In addition, the damage caused by E. doellojuradoi was assessed with the visual inspection of the gills, according to the protocol of Zaixso et al. (2009). The isopod was found almost exclusively in natural benthic habitats, where the prevalence increased with the length of the host. The isopod is a macroparasite and not a commensal as previously suggested because it causes gill damage to the mussel, which increased with the... |

| The development of fish and shellfish farming is facing several challenges linked to the infancy of the industry: i.e. domestication, genetic improvement of disease resistance, genetic improvement of feed efficiency to fish meal and fish oil substitution by vegetal products, development of adapted vaccines, supply of fry or spat at high quality and high robustness, adaptation to environmental change, production of healthy, high quality consumer products and limitation of environmental impact of the activity and escapees. Over recent years, the EU and individual countries have supported the development of genomic tools for some aquaculture species (e.g. rainbow trout, sea bass, sea bream, turbot pacific oyster, Atlantic salmon). New perspectives arise... |

| In the context of the abnormal mass mortality of mussels in France since 2014, Flow CytoMetry (FCM) was used in 2015 and 2016 to study the DNA content and cell cycle characteristics of hemic circulating cells collected from 2000 mussels. The mussels were sampled from 12 wild and cultivated blue mussels stocks distributed along the French Atlantic coast from the south Brittany to Pertuis Charentais areas. During these surveys, various genetic abnormalities were frequently detected, and ploidy characteristics revealed contrasting profiles that corresponded to respective contrasting sanitary status, i.e. healthy mussels with high cytogenetic quality (HCQ) versus diseased mussels with low cytogenetic quality (LCQ). In the present work, FCM and hemocytology... |
