Le programme « Qualité de 1 'huitre creuse Crassostrea gigas développé depuis 1995 par l'IFREMER contient dans ses objectifs l'établissement d'une grille de qualité pour ce coquillage (Grizel, 1998). En l'absence d'étude exhaustive sur la disponibilité et la variabilité de la qualité de C. gigas commercialisée, il apparait difficile d'établir une telle grille. Différents facteurs vont influer les caractéristiques du produit mis en marché sur le plan national. On peut citer en particulier : le secteur géographique d'origine, la période de commercialisation en cours d'année, le mode d'élevage et/ou d'affinage et globalement les pratiques culturales définies par l'éleveur, Pour l'ensemble de ces raisons, un échantillonnage national a été réalisé pendant la... |

Le but de ce programme pathologie est de recherher et d'étudier les agents pathogènes connus et inconnus chez les mollusques bivalves marins, plus particulièrement chez l'huître creuse, Crassastrea gigas, afin d'identifier d'éventuels agents causant des mortalité, de proposer des mesures prophylactiques et de définir des conditions zootechniques permettant aux professionnels de limiter l'impact des maladies sur leur cheptel. La présence de maladies, chez les mollusques bivalves marins dont l'impact socioéconomique peut être catastrophique pour les productions conchylicoles, et l'accroissement des échanges de produits d'aquaculture entre les pays de la CEE et avec les pays tiers nécessitent le renforcement des recherches dans les domaines de la pathologie.... |

La cellule de veille zoosanitaire de La Tremblade s'occupe de trois zones situées au sud de la Loire: la Baie de Bourgneuf, la région de Marennes-Oléron-Charentes, et le bassin d'Arcachon. Ces régions produisent principalement des huîtres creuses. Le naissain d'huîtres creuses produit à Arcachon et en Charente représente près de 80% de la production d'huître creuse, qui sera élevée dans toutes les régions ostréicoles françaises. Un effort particulier avec des prélèvements systématiques a donc été mis en place sur Crassostrea gigas dans ces trois trois zones, notamment sur les larves et le naissain d'Arcachon et de Charente. Compte tenu des transferts fréquents, des animaux sauvages sont prélevés pour caractériser les sites, tandis que la production en... |

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... |

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.... |

The first half of 2007 is characterised by very low summer mortality rates (spring mortality has not been analysed due to the bad quality of the original batch). This low rate concerns the two different size classes of each station except Géfosse (BV02) where a high mortality has been monitored (see SUMON monitoring). Growth seems significant, but the adults' initial weight required a finer analysis. Juveniles had a larger growth than the previous years, and especially on the west coast. On the adult side, maturation was well advanced in June, but the September biometrics showed disparate filling rates between the different stations, and had us suppose that the spawning season was on. |

The Aquaculture Resources department Mollusc Network (REMORA ) has been monitoring in 1994 like in 1993 the growth of homogeneous batches of Crassostrea gigas (initially 18 months old, same origin, same history, same size) in the main French production areas. The monitored parameters deal with growth, morphology, survival, composition and parasite infestations. The comparison between two rearing conditions (traditional bags versus wooden plate to which individuals were stuck) demonstrated like in 1993 improved growth rate (which could also be explained by the lower local density) and a tendency for the oysters to become wider on plates (which is probably related to the absence of shell erosion). Major regional characteristics are revealed by the analysis,... |

The network IFREMER/ REMORA watches every year, from February to December, mortality, growth and quality criteria of two oyster batches ("juveniles" = one-year class ; and "adults" = two-years class), distributed among various stations of the main French oyster areas. This network is a tool for trend estimations (geographic and chronological, on the national scale) ; it must not be regarded as an accurate estimation of professional oyster ongrowings. With regard to REMORA results, generally tallied with professional observations, 1998 on the whole was a second year of low mortality. But some areas remained affected by significant mortalities such as Pen-Bé in South Brittany. The year 1998 was overall a very poor year for growth : the mean oyster weight in... |

This network is a tool for trend estimations (geographic and chronological, on the national scale). With regard to the Breton stations of the network, the year 1999 showed a small increase of mortality rates, both in adults alter their transfer on the REMORA stations and in juveniles during the Summer season. this was particularly observed in Morlaix, Aber Benoît and Pen-Bé. Although it was better than 1998, the year 1999 was a poor year for growth, especially in North Brittany (62.5 g in... |

Every year, from March to December, the IFREMER / REMORA network carries out a survey of mortality, growth and quality criteria of two oyster batches ("juveniles" = one-year ciass ; and "adults" = two-years class), distributed among various stations of the main French oyster areas. In Brittany, this network includes 11 points, to which regional points can be added (15 in 2000). With regard to the Breton stations of the network, the year 2000 showed rather low mortality rates, excepted mortality of several oysters when transfered to the sea. Several areas however had higher mortality rates (> 20%) : l'Arguenon, Morlaix, les Abers, Pen-Bé and Le Croisic. 2000 is a year of good growth in South Brittany (72.8 g in December), more average in North Brittany... |

The monitoring network IFREMER/REMORA in Thau lagoon is assessing, on a yearly basis, mortality, growth and quality criteria distributed among 6 stations. Samplings are carried out in March, June, September and December. 2003 is a year with a very important mortality in Mèze and Marseillan area due to an anoxy and an anormal mortality at Bouzigues Nord in december. The growth rate is always better than others French oysters areas. Afnor index is high (beetwen 13.7 and 16.5 in december), so the totality of the oysters are classifed in "Spéciales". Polydora sp. Index is important but the initial stock was first infected. The valve quality is good, with no gelatine, except on Bouzigues South. |

This report presents the main results for 2002 of the eight points in the Lagune de Thau, in accordance with the monitoring network REMORA: 3 national points and 5 regional added by the «Laboratoire Conchylicole de Méditerranée». Only adults batch is observed in the Mediterranean sea. This year the mortality ratio is low (< 5 %), without significant differences between areas. Like for the whole national network, the average individual weight are less than previous years in Bouzigues and Marseillan area ; in opposite Mèze area has better results. Bouzigues area presents the best productivity rate (3.1) and the worst in the middle of the zone. The AFNOR index, calculed in December, allows to classify the oysters like "spéciales". The best values are... |
