| L'huître appartient à l'embranchement des mollusques, classe des pélécypodes ou lamellibranches, ordre de monomyaires, famille des ostréidés. Les multiples espèces, vivant actuellement dans le monde, il y en a une centaine environ, différent en particulier par la forme variable de leur coquille et par quelques détails de leur organisation interne. Les récentes études des coquilles larvaires, présentant dans leur charnière crénelée des différences remarquables, on permis de déterminer trois genres dans la famille des ostréidés : le genre Ostrea, le genre Gryphaea et le genre Pycnodonta. Sur les côtes françaises, deux espèces sont rencontrées et font l'objet de culture. Ce sont : Ostrea edulis, l'huître plate, et Gryphaea angulata, l'huître portugaise. Le... |

| The general characteristics of the main salmon (Salmo salar L.) stocks in the Massif armoricain (Brittany and Lower Normandy), in the Loire-Allier and in the Adour-Gaves-Nive have been summarized. Due to the poor quality of the previous fishing statistics, there is no clear picture of the historical evolution of the salmon stock. However, a dramatic decrease in the endemic range of Atlantic salmon in France can be shown since the mid-18th century a nd more particularly during the last 50 years. The lack of precise informations describing the size of the catches and the levels of exploitation at sea and in the estuaries make it impossible to estimate the impact that exploitation has led on the evolution of salmon stocks. The mean age of salmon in freshwater... |

| Polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were analysed in the muscle of various edible marine crustaceans (spider crab, edible crab, velvet swimming crab and Norway lobster) from the Brittany and Normandy coasts (France). The highest concentrations were measured in species collected from Antifer (Seine Bay). PCB and PBDE patterns in crustacean muscles were similar and independent of the geographical area with the predominance of the high chlorinated PCBs (CB 15 3, 138, 118 and 180), and of a few PBDE congeners (BDE47, BDE99, WE 100 and BDE28). Oppositely, dioxin contamination differed with site. The major component in crustaceans from the Seine Bay was... |

| The three populations studied were situated on the west coast of Brittany: to the North (Diben), to the West (Tinduff) to the South (Ile Tudy). 25 to 57 analysis were carried out on each of the 19 enzymatic systems where 27 loci had been recognized. Six of which were not interpreted, 10 were monomorphic, 11 polymorphic. Among these latter, the analysis of 4 of the loci were not used as the determination was too confused. Therefore, the comparison of the 3 populations was carried out on 7 polymorphic loci (EST3, HK2, LAP2, MDH1, MDH2, GPI, PGM2). Only a rare allele showed one qualitative difference; this coupled with slight quantitative differences in the distribution of the alleles did not permit to distinguish the three various populations. The genetic... |

| Introduction and objectives of the study: Understanding the operation modes of the coastline systems requires the study of the hydrodynamics responsible for transporting the whole of the chemical and biological elements of which they are composed. The idea of maintaining a close connexion between the physics, biology, geology and chemistry of the oceans is not new, and was for that matter the subject of a note in the first report of the International Council for the Study of the Oceans (ICSS) in 1902 (Sverdrup et al., 1954): " it was seen from the beginning that the study of the physical conditions, of the chemical nature of the ocean waters, of the currents, etc., was of the greatest importance for the investigation of the problems connected with life,... |

| A 5-month experiment combining a geochemical survey of metals with a bioaccumulation study in batches of Crassostrea gigas was conducted in two shellfish farming areas and a marina in Normandy (France). Various endpoints at different levels of biological organization were studied. ROCCH data showed differences in biota contamination between the two shellfish areas but the present study revealed only slight differences in metallic contamination and biomarkers. By contrast, significantly different values were recorded in the marina in comparison with the two other sites. Indeed, higher levels of Cd, Cu and Zn were measured in the oysters from the marina, and these oysters also showed a poorer physiological condition (e.g., condition index, histopathological... |

| During the cruise EURHOGLI (Eutrophication by the Rhone of the Gulf of Lion) of the R.V. Le Noroit , a grid of stations covering the dilution area of the Rhone River has been carried out two times with a time interval of about two weeks. An exceptional growth during the two months preceding the cruise, has produced an important dilution effect over a wide spread areas. The absence of nutrients demonstrates their general consumption by biological activity. The tracer properties of the nutrient can be observed only in a small area near the mouth of the river. Nutrients are becoming the tracer of this dilution, and a great development of chlorophyll associated to this same area, show that nearly all the biological activity of nutrient assimilation is... |

| This document, which is the eighth edition of a series started in 2000, provides a global overview of the data collected in 2011 as part of the Fisheries Observatory of Ifremer. It aims to present a summary of the activity and economic situation of the French fleets operating in the North Sea, English Channel, Northeast Atlantic and Mediterranean Sea in 2010. It updates the 2009 issue, which was published in 2011. This synthesis is intended for a wide audience. The document contains several fact sheets: • The first sheet provides a description of the French national fishing fleet (North Sea - Channel, Atlantic and Mediterranean Sea, excluding overseas), including vessel and crew characteristics. It also presents the evolution of the French fishing fleet... |

| The fish remains sampled from archaeological sites are generally the result of human food refuse; therefore, the study of retrieved fish scales may provide reliable information on the season of capture and on paleoclimate and paleoenvironmental changes. Among Western European freshwater fishes, the grayling, Thymallus thymallus¸ has the most easily recognizable scales and is a commonly recovered species from Paleolithic contexts. This study, therefore, is based on the growth pattern analysis of modern and archaeological scales from grayling specimens. The modern specimens were collected monthly in France (n = 22), Switzerland (n = 16), Finland (n = 20) and Sweden (n = 10). Scale growth patterns were measured using numerical analysis to a high accuracy. The... |

| An extensive restocking experiment has been undertaken in 1977 on a tributary of Elorn river in the framework of an Atlantic salmon management program of this river of northern Brittany. The results gathered during this experiment permitted the analysis of S. salar production during the juvenile and adult stages from immersion of unfed fry of Irish origin in small nursery streams. The annual production during the first year represented 72% of the total production of two years of growth. Adult runs into the nursery stream were observed between mid-November and mid-December. These runs were initiated by high increases of flow rates of the nursery stream. The whole of the adult population is constituted by late grilses whose female. Their rate of return was... |

| This document presents a survey of the sea-related activities in France, i.e. those of the commercial sector (exploitation of mineral and living resources, manufacturing industries, services) and those of the non-commercial public sector (Navy, State services, education, safety, marine research). A chapter is devoted to the protection of the coastal and marine environment. Each activity of the commercial sector is described by key-figures (turnover, value added, employment); the description of the non-commercial public sector includes data on costs, including personnel costs. In addition to these figures, qualitative information is given on the recent development, present situation and future prospect of each activity. This set of data and information... |
