| Dans le cadre de la Directive Cadre Européenne sur l’Eau, le Ministère a confié au Cemagref de Bordeaux le développement d’un indicateur « poisson » dans les eaux de transition et notamment les lagunes méditerranéennes. Une première campagne d’acquisition à l’échelle de la façade a eu lieu en 2006. En 2009, l’Agence de l’Eau Rhône-Méditerranée et Corse a confié à l’Ifremer la réalisation d’une campagne d’échantillonnage sur trois lagunes corses : Diana, Urbino et Palo. Pour répondre aux besoins de la DCE, cette campagne a respecté le protocole du Cemagref. L’indicateur « poisson », dans sa forme actuelle, a été appliqué aux données recueillies. L’étang de Diana est classé en bon état alors que les étangs d’Urbino et de Palo sont classés en état moyen.... |

| Depuis 1992, la surveillance de la santé des mollusques marins du littoral français est assurée par le réseau de Pathologie des Mollusques (Repamo). Ses activités s’inscrivent dans le cadre de la Directive Européenne 2006/88/CE. Depuis son évaluation par la plateforme nationale d’épidémiosurveillance en santé animale en 2012, l’objectif de surveillance est la détection précoce des infections dues à des organismes pathogènes exotiques et émergents affectant les mollusques marins sauvages et d’élevage. L’année 2015 est la première année de transition pour laquelle un début d’évolution des modalités de surveillance de la santé des mollusques marins animées par l’Ifremer a été amorcé. Un dispositif hybride de surveillance a été mis en place, s’appuyant sur... |

| The construction of marinas along the shoreline has caused substantial habitat destruction within the sheltered coastal areas previously used as nursery grounds by many fish species. However, although the negative ecological impacts of these constructions have been reported extensively, their potential roles in the functioning of the coastal zone remain largely unknown. Here, we surveyed the juveniles of 4 Diplodus species in 5 marinas located along the French Mediterranean coast to assess whether rocky fishes can successfully settle inside these artificialized coastal areas. Inter-specific differences in the spatiotemporal use of the various artificial habitats provided by marinas were investigated between April and August over 2 consecutive years. We... |

| Mercury (Hg) is a global contaminant of environmental concern. Numerous factors influencing its bioaccumulation in marine organisms have already been described at both individual and species levels (e.g., size or age, habitat, trophic level). However, few studies have compared the trophic characteristics of ecosystems to explain underlying mechanisms of differences in Hg bioaccumulation and biomagnification among food webs and systems. The present study aimed at investigating the potential primary role of the trophic status of systems on Hg bioaccumulation and biomagnification in temperate marine food webs, as shown by their medium-to high-trophic level consumers. It used data from samples collected at the shelf-edge (i.e. offshore organisms) in two... |

| Chemical contamination levels and stable isotope ratios provide integrated information about contaminant exposure, trophic position and also biological and environmental influences on marine organisms. By combining these approaches with otolith shape analyses, the aim of the present study was to document the spatial variability of Hg and PCB contamination of the European hake (Merluccius merluccius) in the French Mediterranean, hypothesizing that local contaminant sources, environmental conditions and biological specificities lead to site-specific contamination patterns. High Hg concentrations discriminated Corsica (average: 1.36 ± 0.80 μg g− 1 dm) from the Gulf of Lions (average values < 0.5 μg g− 1 dm), where Rhône River input caused high PCB burdens.... |

| En Méditerranée, des campagnes de surveillance sont mises en œuvre tous les 3 ans depuis 2006 pour répondre aux objectifs de surveillance des eaux côtières et de transition. Ce rapport présente les résultats de la cinquième campagne réalisée par l’Ifremer en 2018. Le caractère pluridisciplinaire de ces campagnes de surveillance a été maintenu pour d'une part répondre à l'ensemble des enjeux de la DCE, et, d’autre part, acquérir des données en lien avec le programme de surveillance de la Directive Cadre Stratégie pour le Milieu Marin (DCSMM, 2008/56/CE). La campagne 2018 a permis : - la mise en œuvre par l’Ifremer de stations artificielles de moules selon la méthodologie RINBIO dans l’ensemble des masses d’eau côtières (MEC) et sur 10 masses d’eau de... |

| Concentrations of 6 trace metals (Ag, Cd, Cu, Ni, Pb, Zn) in the muscle of 2 sharks (Galeus melastomus and Scyliorhinus canicula), 4 teleosts (Helicolenus dactylopterus, Lepidorhombus boscii, Micromesistius poutassou and Phycis blennoides) and 1 crustacean (Nephrops norvegicus) were compared between the Bay of Biscay (Atlantic Ocean) and the Gulf of Lions (Mediterranean Sea). Although average concentrations and the trace element pollution index were generally higher in the Gulf of Lions, significant differences between the two ecosystems were only found for Zn for Helicolenus dactylopterus, and for Ag and Cu for the crustacean N. norvegicus. Moreover, some relationships between trophic level or size and metal concentrations were found for these two... |

| Mercury (Hg) is one of the main chemicals currently altering Mediterranean ecosystems. Red mullet (Mullus barbatus and M. surmuletus) have been widely used as quantitative bio-indicators of chemical contamination. In this study, we reassess the ability of these species to be used as efficient bio-indicators of Hg contamination by monitoring during 18 months Hg concentrations in muscle tissue of mullet sampled from 5 French Mediterranean coastal areas. Mean concentrations ranged between 0.23 and 0.78 μg g−1 dry mass for both species. Values were consistent with expected contamination patterns of all sites except Corsica. Results confirmed that red mullets are efficient bio-indicators of Hg contamination. Nevertheless, the observed variability in Hg... |

| Sharks are a diverse group of mobile predators that forage across varied spatial scales and have the potential to influence food web dynamics. The ecological consequences of recent declines in shark biomass may extend across broader geographic ranges if shark taxa display common behavioural traits. By tracking the original site of photosynthetic fixation of carbon atoms that were ultimately assimilated into muscle tissues of 5,394 sharks from 114 species, we identify globally consistent biogeographic traits in trophic interactions between sharks found in different habitats. We show that populations of shelf-dwelling sharks derive a substantial proportion of their carbon from regional pelagic sources, but contain individuals that forage within additional... |

| In the context of the European Water Framework Directive (WFD), monitoring programs and related indicators have been developed to assess anthropogenic impacts on various components of aquatic ecosystems. While great precautions are usually taken when selecting and calculating relevant core metrics, little attention is generally paid to the generation of the multimetric indicator, i.e. the combination of the different core metrics. Indeed, most multimetric indicators are generated by simply averaging or summing metrics, without taking into account their sensitivity and their variability. Moreover, few indicators provide a rigorous estimate of the uncertainty of the assessments, while this estimation is essential for managers. In this context, we developed a... |

| Blue shark (Prionace glauca) and shortfin mako (Isurus oxyrinchus) specimens were caught in the North-eastern A tlantic O cean by S panish and Portuguese longliners. They are considered as top-predators, particularly susceptible to bioaccumulate mercury (Hg). The H g mean levels in blue shark and shortfin mako were 0.4 (SD = 0.3 mg kg-1) and 0.5 (SD = 0.9 mg kg-1), respectively. The body mass index (BMI) was tested to demonstrate the accumulation of H g in these two top-predators, taking into account size (TL, cm) and mass (W, kg) simultaneously. The comparison of these three methods showed that the BMI could be a relevant biological indicator of the accumulative H g process for sharks. |

| Background. There is need for more information on behavioural rhythms of fishes in relation to their habitat use in few or not previously monitored areas, such as coralligenous habitats. Some studies have compiled inventories of observable fish species in this habitat, but no studies have been performed on the temporal patterning of fish behaviour, especially at the scale of the day. The presently reported study aims at providing knowledge on finescale fluctuations of abundances and behaviour of two fish species in coralligenous habitats throughout the diurnal period. Materials and methods. Fish fauna was filmed hourly, for several days, from dusk to dawn, with autonomous, programmable, and rotating video systems. Diurnal variations in abundances per... |

| Pelagic sharks (blue shark Prionace glauca and shortfin mako Isurus oxyrinchus) caught by long-line Spanish and Portuguese fleets in the NE Atlantic, were sampled at Vigo fish market (Spain) for total mercury (Hg) analysis. Hg concentration in white muscle increased with size and weight in both species, but at a higher rate in shortfin mako than in the blue shark. No difference was found with sex, year and season. Spatial variation was observed in the blue shark with higher Hg values in the North of the Azorean archipelago, but not in the shortfin mako. These high-level predators are particularly susceptible to bioaccumulate contaminants (Hg) in their tissues (muscle). However, a significant positive relationship between Hg concentration and trophic level... |

| High abundances of juvenile fish in certain ports suggest they might provide alternative nursery habitats for several species. To further investigate this possibility, post-settlement growth, metal uptake and body condition were estimated in 127 juveniles of two seabream species, collected in 2014–15, inside and outside the highly polluted ports of the Bay of Toulon. This showed that differences in local pollution levels (here in Hg, Cu, Pb and Zn) are not consistently mirrored within fish flesh. Muscle metal concentrations, below sanitary thresholds for both species, were higher in ports for Cu, Pb and V only. Otherwise, fish muscle composition principally differed by species or by year. Juvenile growth and condition were equivalent at all sites. Higher... |
