| Although the broad concept of mental models is gaining currency as a way to explore the link between how people think and interact with their world, this concept is limited by a theoretical and practical understanding of how it can be applied in the study of human-environment relationships. Tools and processes are needed to be able to elicit and analyze mental models. Because mental models are not directly observable, it is also important to understand how the application of any tools and processes affects what is measured. Equally important are the needs to be clear on the intent of the elicitation and to design the methods and choose the settings accordingly. Through this special edition, we explore how mental models are elicited using two approaches... |

| The document synthesizes the data collected in 2002 and 2003 as part of the Fisheries monitoring system of Ifremer. It updates the description of the status in 2000 of the French fishing fleets operating in the North Sea, Channel and Atlantic (produced in 2002). The document is made of a series of leaflets. The first leaflet provides a global description of the overall population of fishing vessels. Information provided includes vessel and crew characteristics, spatial distribution of fishing activity and catch, and gears used. A description of fleets (sub-groups of vessels using the same gear combinations) is also provided at both national and regional levels. The following leaflets provide a detailed description of the fishing activity and economic... |

| Discolored waters and human diseases by shellfishes were dominant features of summer 1983 in south coast of Brittany. Vilaine Bay, the most damaged area, was successively affected by brown waters in early June, and diarrhetic intoxications by harvested mussels (July and August), just as DPS producing dinoflagellate (D. acuminata ) reached higher water or mussel guts concentrations than years before. Outspreading in the whole south coast of Brittany and possible relation with hydrological or biological parameters are analyzed. |

| The author studies the microbial phenomena which occur during the maturation of French anchovies, some from the Basque, the others from the Roussillon coast. There are some differences in relation with the origin of the fishes. On a marine agar, the microflora of the Mediterranean ones is almost constant or in a light diminution while that of the Atlantic ones is climbing during 9 weeks before a decline. On an extremely salted agar and in the both origins the archaebacteria are increasing in number during 5 to 6 weeks and diminishing before. The complete ripening is obtained within 16-17 weeks. The limits of the significance of the microbiological analysis are discussed. |

| French regulations concerning the mitigation of development impacts have been progressively strengthened with offsets now required for impacts on forests, wetlands, and protected species, among others. In 2012, following a national consultative process called Grenelle de l’Environnement, legal requirements in terms of monitoring and effective implementation of measures aimed at avoiding, reducing and offsetting impacts were strengthened. This has created strong “demand” for offsets. The workability of these new requirements has come under scrutiny, not least because of their strong legal and financial implications for developers. In this context, official government guidance on implementing the mitigation hierarchy was published in 2012. Under this... |

| This study aims to describe the patterns of soft bottom macrozoobenthic richness along French coasts. It is based on a collaborative database developed by the “Réseau des Stations et Observatoires Marins” (RESOMAR). We investigated patterns of species richness in sublittoral soft bottom habitats (EUNIS level 3) at two different spatial scales: 1) seaboards: English Channel, Bay of Biscay and Mediterranean Sea and 2) 0.5° latitudinal and longitudinal grid. Total observed richness, rarefaction curves and three incidence-based richness estimators (Chao2, ICE and Jacknife1) were used to compare soft bottom habitats species richness in each seaboard. Overall, the Mediterranean Sea has the highest richness and despite higher sampling effort, the English Channel... |

| Le ROCCH produit les données chimiques nécessaires à l'évaluation de la qualité chimique des eaux marines, et notamment la qualité des zones conchylicoles françaises. En 2020, un total de 110 échantillons de mollusques collectés et analysés (dont 40 points hors zones conchylicoles suivies) permet de dresser un bilan de la qualité des côtes métropolitaines. Un secteur présente une non – conformité avec le dépassement de la teneur admissible en plomb dans les moules de la baie de Daoulas (sud – est de la rade de Brest). Plusieurs secteurs atteignent ou dépassent 50 % de la concentration-seuil : le nord de la rade de Brest (HAP), le sud de la rade de Brest (plomb et cadmium), le pertuis charentais (cadmium), l’estuaire de la Gironde (cadmium), l’étang de... |

| Depuis une vingtaine d'années, l'Ifremer organise des campagnes de pêche scientifique en mer du Nord, Manche, Atlantique et Méditerranée concernant les ressources pélagiques, démersales et benthiques. L'objectif prioritaire est de produire des indices d'abondance des principales espèces commerciales. Elles recueillent également des données sur les espèces capturées non commerciales. Les campagnes sont réalisées selon des plans d'échantillonnage standardisés. L'engin de pêche et son gréement, la position des stations, le tri des captures, les prélèvements biologiques suivent des protocoles fixés. Chaque zone étudiée est découpée en fonction de la profondeur, de la latitude ou d'autres critères. L'échantillonnage prévoit un nombre de traits de chalut... |

| 1. Introduction: network organisation in 1997. The REMORA network - REseau MOIIusques du département Ressources Aquacoles de l'Ifremer - (Ifremer's Aquaculture Resources Department Mollusc Network) has been evaluating, since 1993, hollow oysters' growth (Crassostrea gigas) in major French oyster beds. In order to do so, it has followed up on a yearly basis the growth of a unique oyster batch shared among different stations in the main French raising areas. Releasing takes place in February and picking happens in November or December; intermediary sampling is done in June and September. All operations happen on the same dates for all stations. A national report is published each year. 'Regional' stations are sometimes added to the national network, but they... |

| To provide updated information on the growth of Crassostrea gigas in Brittany, experimental stations on 8 sites (culture area) were monitored. Biometric measurements (length, width,...), meat composition (proteins, lipids, carbohydrates...), quality, survival and parasitism were observed after 7 months. A descriptive study by principal components analysis was conducted to find the most significative variables explaining the variability and classifying the sites. Six groups of station can be identified by their respective performances that have been screened in detail. An optimal strategy was discussed to establish a most efficient data network in Brittany. The yearly variations will be checked up and their correlations with environmental factors tested... |

| The present study investigates the chemical composition of wet atmospheric precipitation samples on a daily and an intra-event timescales in Opme, an experimental meteorological station located near Clermont-Ferrand, France. The samples have been collected from November 2005 to October 2007. A total of 217 rainwater samples, integrated for 24 h, were collected and analyzed for pH, conductivity, Na+, K+, Mg2+, NH4 (+) , Ca2+, Cl-, NO (3) (-) , SO (4) (2-) , PO (4) (3-) and HCO3 (-) . The composition of the rainwater collected appeared to be controlled by the following potential sources: neutralisation process (association among calcium, ammonium with nitrate and sulphate), marine and terrestrial sources. In order to determine the role of long-range... |

| Environmental conditions ultimately leading to blooms of the toxic dinoflagellate Alexandrium catenella/tamarense were investigated at two Mediterranean sites (Annaba Bay, Algeria and Thau lagoon, France). Three years were examined in details: 1992 (a pre-Alexandrium period), 2002 (a year with the first bloom in Annaba) and 2010 (a year with a major bloom in Annaba). Most conditions were similar, but ammonium concentrations were much higher in Annaba (up to 100 μM) than in Thau (up to 10 μM). First records of A. catenella/tamarense were in 1995 for Thau and 2002 for Annaba, and coincided with soluble reactive phosphorus (SRP) decreasing below a concentration of about 1 μM. No other environmental variable could be related to those blooms. Thus, it is likely... |

| The "Artificial reefs" and "Repopulating" issues have been tackled by the Ifremer for a number of years without reaching a clear cut point of view, mainly for lack of socio-economic elements necessary to a rigorous analysis of these devices and practices. During a mission in Japan in January 2006, some Japanese experts, have presented to the head of the Ifremer a few examples of realisations related to these fields and conducted in their country. The head of the Ifremer realised the scope of such devices in Japan and expressed the wish to see an in-depth study carried out over there. In this purpose, the International Relationship Department organised and co-financed the three-month stay in Japan of a student from the University of Montpellier III, Sylvain... |

| The indigenous oyster of mainland France, the fiat oyster, Ostrea edulis has been part of the human diet for centuries. The Romans collected them and exported them to Rome. Although tanks for holding oysters after harvesting were in use at that time (GreIon 1978) it seems that true culture was not developed along the coast contrary to the records of Pliny the Older. It appears that oysters were already being captured on hoards off the Italian coast. The exploitation of natural stocks continued through the Middle Ages and the Renaissance. However, it was not until the 17th century that oyster culture began, first in the pools of the salt marshes of the Atlantic coast and then in specially managed ponds. Papy (1941) repeats a good description given in 1688... |
