The wide range of data from the French Ifremer/REMORA network, collected since 1993 allow a global characterization of mortalities of 1-year old and 2-years old cupped oysters Crassostrea gigas, that are cultivated in the main French oyster areas (Fleury et al, 2003), and thus a better understanding of the causes of these mortalities (Ifremer /MOREST project). The average annual mortalities on intertidal sites range from 10 to 20%. Most of the mortalities take place in Spring and Summer. 1-year oyster mortalities occur in Marennes and several sites in Brittany whilst 2-years oyster mortalities occur in the same sites and in baie des Veys (Normandy). In addition, 2-years oyster mortalities appear more variable according to different annual surveys.... |

In order to find the global parameters which could explain the growth of Pacific Oyster Crassosrrea gigas. a survey of Pacific Oyster's growth has been done in Brittany from 1990 to 1995 and in France from 1993 to 1995. The analysis shows the positive influence of rain amount on weight grov,th except in eutrophic areas where it is the contrary. It also shows the positive influence of temperature provided it stays within an optimal range. statistically defined. Some characteristics of the production areas have been reviewed without achieving clear explanation of growth differences between sites. Further studies are necessary particularly in hydrodynamics and primary production determinism to progress. |

The network IFREMER/REMORA has watched every year, since 1993, from February to December, mortality, growth and quality criteria of two oyster class-size ("juveniles" of the first-year c1ass and "adults" of the second year c1ass), distributed among various stations of the French oyster areas. This has provided a quite standard and simple annual assessment of the rearing results, generally tallied with professional observations. From year to year, data series have been obtained, from which mean values (references), chronological trends or spatial differences can be analysed. Results in Brittany, from 1993 to 1998, show that, in a "normal" year, 30 g oysters grow to 60-80 g at the end of the year, with a mortality rate of 10-15%. Mortality occures mainly in... |

Le réseau régional REMONOR est un dispositif d’observation des performances annuelles de mortalité, croissance et qualité des huîtres creuses. Le protocole s’attache à surveiller des individus de deux classes d’âge (« adultes » = 2 ans et « juvéniles » = 1 an) réparties entre différentes stations dans les principaux secteurs ostréicoles normands. Ce réseau est mené conjointement par le LERN (Laboratoire Environnement Ressources de Normandie) et le SMEL (Synergie Mer Et Littoral) qui mettent en commun leurs moyens humains et techniques de façon à suivre les 10 stations du réseau sur l’ensemble de la côte Bas-Normande. Une nouvelle fois, la mortalité estivale du naissain est très importante, plus particulièrement sur la côte Ouest du Cotentin. Sur ce... |

Since 1998, a growth and quality monitoring study of reared molluscs has been developped as part of a close collaboration between the Shellfish Research Laboratory of Normandy (IFREMER Port-en-Bessin, Calvados) and the SMEL (Syndicat Mixte d'Expansion du Littoral) Experimental Centre (Blainville, Manche). REMONOR (REseau MOllusque de NORmandie) is based on the experience gained through the national monitoring network REMORA, which protocol has been entirely applied. Adults and spat of Pacific oysters Crassostrea gigas were placed in 13 stations all along the oysters rearing areas of Normandy. These oysters had the same origin and history (i.e. age and weight) until they were dispatched on the 13 stations. 4 essential criteria were used to monitor rearing... |

At the end of its third year, the regional network for monitoring REMONOR, confirms the particularities of oyster from Normandy in matter of growth and quality. Results from 2 000 are globally very close of those from 1998. Mortality of adults reached 14% and juvenile 6% which represent a low death rate. For this year the most blow area is the Baie des Veys with 31% death rate at Géfosse. Observed growth this year had been weaker than the past two years despite the spring and automnal growth. At spring, the higher recorded growth rate on the West coast with 0.42% (regional average : 0.29%). This seasonal trend seems more and more obvious every year. Regarding the classification of the special oysters, despite the change of the standard, the Baie des Veys... |

The national REMORA network is targeted on the studies of growth, flesh quality and mortality of a sample of cupped oyster Crassostrea gigasdistributed on 9 stations along the coast of Normandy. As a better precision is needed for regional purpose, 7 new stations have been added. A total number of 16 stations is now sampled from Chausey to Meuvaines. Weak rates of mortality have been noticed in 2002 on both adults (7%) and spat (6 %). These rates are the weakest ever seen. The mortality rates in the Baie des veys were less than 10 %. This rearing area shows usually a much higher mortality level. Growth rates were noticed weaker than usual. They slowly decline from 1999. From Mach to December, the growth rate of adults has been computed to 0,21 %/day (for a... |

The network named REMONOR (REseau MOllusqueNORmandie) aims to assess mortality, growth and tissue quality of the Pacific oyster, Crassostrea gigas, cultivated in Normandy over an annual cycle. This local network relies on the same material and methods as the national one named REMORA (REseau Mollusques Ressources Aquacoles). The study was carried out in 17 sites, which were distributed in the four basins where oyster rearing occurs in Normandy (West and East coast of Cotentin, Baie des Veys and Meuvaines). In 2003, a new site was added, which was located in the area of Ver-Sur-Mer (Calvados). The results obtained in 2003 showed a low annual mortality for adults (8%) as well as for juveniles (10%). Growth was also low for the two age classes of oyster... |

The regional monitoring network REMONOR, relying on the experience of IFREMER's REMORA national network, each year assesses the mortality, growth and quality for two age classes ("adults" = 2 years and "juveniles" = 1 year) of cup oysters, distributed among various farm sites in the main oyster farming sectors of Lower Normandy. This network, led in collaboration by LERN (Environment Resources Laboratory) and SMEL (Coastline Installations Public-Private Entity), this year welcomes a new farm site in Veules les Roses, in Seine Maritime (76), bringing to 18 the total number of monitored sites. For operational reasons, a reduced monitoring protocol was conducted in 2005 on this last farm site, which will not take on the network's standardised protocol until... |

Le réseau régional de suivi REMONOR s'appuyant sur les acquis du réseau national REMORA de l'Ifremer, évalue chaque année la mortalité, la croissance et la qualité sur deux classes d'âges d'huîtres creuses (« adultes » = 2 ans et « juvéniles » = 1 an), réparties entre différentes stations dans les principaux secteurs ostréicoles Bas-Normands. Ce réseau, mené en collaboration par le LERN (Laboratoire Environnement Ressources de Normandie) et le SMEL (Syndicat Mixte de L'Equipement du Littoral), intègre deux nouvelles stations en 2006 : Veules les Roses (VR01), dont le suivi, allégé l'an dernier, est aujourd'hui complet et Denneville (CO10) qui doit compléter les connaissances sur le nord de la Côte Ouest du Cotentin. Une station est à l'étude cette année... |

Each year, the regional network REMONOR assesses the mortality, growth and quality of cupped oysters in two age classes ("adults", 2 years old; "juveniles", 1 year old) at various stations in the main oyster farming areas in Normandy. We used the protocol established by the national network REMORA. REMONOR is implemented by the Normandy Environment Resources Laboratory (LERN) in conjunction with the Joint Association for Coastal Fisheries (SMEL). This year, a new station at Fermanville (NC01), in the north of the Manche "département», was integrated into the network. This is the first deep-water station of the regional network.... |
