| Thiis report aims to study the oyster Crwsosrrea gigas growth and production over a 12 years time' s span in the bay of Marennes-DIeron. Results of 12 years of oyster growlh did not show any significant oyster biological productivity decrease, nor trend. ln contrast, annual growth showed a large variability, which will be correlated with environmental conditions. Moreover, annual growth variability was greater than the variability due to site location,. besides the Ronce experimental site. The later, located in the south west part of the bay of Marennes-Dleron, has been the leading oyster growth site since 1989. The annual shell growlh variabiliry was greater than oyster dry meat weight fluctuation . Both 1990 and 1991 years were characterized by the... |

| Le réseau de veille zoosanitaire des mollusques, REPAMO, a été créé en 1992 afin de protéger les espèces d'intérêt économique des maladies susceptibles de les affecter. En effet, de même que les autres productions animales, la conchyliculture est frappée par diverses maladies dont certaines se comportent comme des facteurs limitants de la qualité ou de la quantité des productions. L' histoire de l'ostréiculture française a connu de tristes expériences en la matière, notamment dans les années 70 pour l' huître creuse portugaise, Crassostrea angulata ou encore pour l'huître plate, Ostrea edulis. En fait, nous ne disposons que de très peu de possibilités de protéger les mollusques bivalves vis à vis des maladies infectieuses. D' une part, les traitements,... |

| Ce programme fait l'objet d'un effort de recherches croissant depuis 1995. On peut rappeler que la première année d'étude s' est focalisée sur l'enregistrement des conditions environnementales au moyen d' une sonde SUBER et de l'étude des conditions de maturation des huîtres. Le programme 1997 a consisté à vérifier cette hypothèse de travail par une étude in situ d' une population homogène d' huîtres réparties (en une à une) à plat et en surélevé sur 15 sites géographiques couvrant l'ensemble des bancs de Ronce Perquis selon une distribution est-ouest et bathymétrique. Concernant la valorisation des claires ostréicoles - Optimisation de l'affinage, l'objectif de ce programme est d'analyser le fonctionnement du marais ostréicole traditionnel afin de mieux... |

| Shelled molluscs are comprised of bivalves and gastropods. They are settled mainly on the continental shelf as benthic and sedentary animals due to their heavy protective shell. They can stand a wide range of environmental conditions. They are found in the whole trophic chain and are particle feeders, herbivorous, carnivorous, and predators. Exploited mollusc species are numerous. The main groups of gastropods are the whelks, conchs, abalones, tops, and turbans; and those of bivalve species are oysters, mussels, scallops, and clams. They are mainly used for food, but also for ornamental purposes, in shellcraft industries and jewelery. Consumed species are produced by fisheries and aquaculture, the latter representing 75% of the total 11.4 millions metric... |

| France is presently one of the leading countries in Europe for shellfish production with 152,000 metric tonnes of the Pacific cupped oyster C. gigas, 2,500 tonnes of flat oyster O. edulis, and more than 60,000 tonnes of mussels M. edulis and M. galloprovincialis. Moreover, species like the pearl oyster Pinctada margaritifera in French Polynesia, and on the Atlantic coastline the scallop Pecten maximus and the Manila clam Tapes philippinarum contribute significantly to the overall landings. . Since traditional rearing areas are now almost overloaded, new management practices are currently under review to optimise and develop shellfish culture. Besides the products resulting from genetic research (e.g. triploids, tetraploids and disease resistant strains),... |

| France is currently one of the leading shellfish production countries in Europe, harvesting more than 150,000 metric tons of the Pacific cupped oyster (Crassostrea gigas) and 60,000 tons of mussels (Mytilus edulis and M. galloprocincialis) each year. Among rearing areas, the Charentais Sounds and the Marennes-Oleron Bay rank first in Europe, with an annual production of 40,000 and 15,000 tons of oysters and mussels respectively. More than a third of French production is marketed from the Marennes-Oleron area. As natural C. gigas and M. edulis spatfall is limited to the Atlantic coast, the Marennes-Oleron Bay and the Charentais Sounds play a critical role nationally, representing more than half of French oyster and mussel spat production. The stocking... |

| Initiated in 2013, the present work carried out in 2014 extends the monitoring network focusing on marine invasive exotic species in Saint-Pierre and Miquelon archipelago. In a global context of coastal ecosystems’ changes, accentuated by direct or indirect effects of human activities, it became essential to implement a monitoring survey and to track the expansion of marine invasive species along Saint-Pierre and Miquelon shoreline. Fukui traps and tunicates collectors deployed on different stations as well as the timely completion of observational dives, have provided the following conclusions: several invasive species were again reported within the local marine ecosystem. Those species, i.e., Carcinus maenas, Caprella mutica, Ciona intestinalis,... |

| An international community of biologists presents the Pacific oyster Crassostrea gigas as a candidate for genome sequencing. This oyster has global distribution and for the past several years the highest annual production of any freshwater or marine organism (4.2 million metric tons, worth $3.5 billion US). Economic and cultural importance of oysters motivates a great deal of biologic research, which provides a compelling rationale for sequencing an oyster genome. Strong rationales for sequencing the oyster genome also come from contrasts to other genomes: membership in the Lophotrochozoa, an understudied branch of the Eukaryotes and high fecundity, with concomitantly high DNA sequence polymorphism and a population biology that is more like plants than any... |

| The oyster population in the Maryland portion of the Chesapeake Bay has declined b y more than 38-fold since the early part of the century. Although the effects of fishing have been implicated, the decline has been attributed primarily to water quality and recently oyster disease. The decline has also been thought to have affected the biota and chemistry of the Bay. Our analysis provides a quantitative demonstration that the long-term declines are largely the result of habitat loss related to over fishing early in the century, stock over fishing, early in the century' through the recent times. Furthermore, the major ecological effects on Chesapeake Bay occurred well-before World War 1/, before industrialization and the prevalence of disease |

| The French mussel industry produces around 60,000 metric tons on a yearly basis using two common species: Mytilus edulis, which is widely distributed along the Atlantic coastline, and Mytilus galloprovincialis, distributed mainly on Mediterranean shores. This production represents only half of the yearly consumption of mussels in France, leading to large imports from Spain and the Netherlands. Most imports occur between September and March, when the Atlantic production is reduced because of low meat quality due to spawning events. Although a public mussel fishery still exists, most production is based upon 3 culture techniques: on-bottom culture, longline and suspended culture, and bouchot-type culture, with the latter being developed in the l3lh century.... |

| The Pacific oyster Crassostrea gigas: from an introduced species for aquaculture to an invasive species for the ecosystem Miossec L. and Goulletquer Ph. The Pacific oyster Crassostrea gigas has been introduced worldwide for aquaculture purposes since the beginning of the last century. In most of the countries the species established broadly, emphasizing its ability to adapt to a wide range of environmental conditions. In Europe the Pacific oyster was massively introduced in the 1970s especially into France after mass mortalities of the Portuguese oyster Crassostrea angulata affected by a viral disease. Good environmental conditions in some French areas on the Atlantic coast induced successful recruitments in the following years. The population became... |

| Assessments of the quantity of organic matter in shells were made both by ignition at 475°C and by chemical extraction in O1M trichloroacetic acid. The quantity of organic matter obtained by ignition at 475°C was over-estimated by 2 to 48 times, depending on the species studied (Ruditapes philippinarum, Cardium edule, Cardium glaucum). A technique of extraction by OlM trichloroacetic acid, filtration on Whatman CFjC filter and weighing of remaining ashes after ignition (450°C) is proposed, Energy values of the shell organic matter varied from 1700(±060) Jmg 1 to 240 (±2'87) Jmg 1 depending on the species and the geographic location. In the energy budget, these methods have made it possible to obtain an estimate of the energy mobilised in the... |

| The krlging technique Is now employed ln more and more fields: mlnlng (Journel. 1977), hydrology (Delhomme, 197B; Shamsi et al" 1988; Dingman et al" 1988), fishery (Conan, 1989) and ecology (Robertson, 1987; Schotzko and O'Keeffe, 1989, 1990). Recent developments of the mathematlcal theory tend to extend the number of applications where Il may be used. Baslcally defined for the case of a statlonary spatial process, It now encompasses more general processes assuming less and less strong hypotheses (Intrinsic hypothesls, Intrlnsic generalised hypothesis, disjunctive krlglng). In its most general formulation, it allows to study the spatial structure of a process including large scale or local trends. The basic idea remains to take Into account the spatial... |
