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... |

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... |

The monitoring network IFREMER /REMORA is assessing, on a yearly basis two oyster batches ("juveniles" = one-year old ; and "adults" = two-years old), distributed among various stations of the main French oyster areas. Samplings are carried out in March, June, September and December. In this way this network assess seasonal mortality, growth and quality of cupped oysters, in which it is a tool for trend estimations, and then for ecosystem management or scientific studies. However, it must not be considered as an accurate estimation of professional oyster ongrowings. 2002 has been a year of very few mortality (6% in average for "adults" and 11% for juveniles). Only 2 batches were over 15% mortality. The mortality is a bit higher in juveniles batches' with 5... |

En 2006, le cheptel d'origine d'huîtres adultes présentait un poids moyen individuel de 28,8g. La mise à l'eau s'est effectuée entre le 13 et le 17 mars 2006 sur les stations Manche et Atlantique et le 20 mars en Méditerranée. Au niveau national, la croissance observée en 2006 pour les adultes s'avère bonne, avec des valeurs supérieures à la moyenne en Normandie (+9,6%), en Bretagne Nord (+24,7%) et dans les Pays de la Loire (+11,7%). En revanche, les performances sont médiocres dans le bassin d'Arcachon (-13,3%). En Méditerranée, le poids atteint en décembre est plus faible que la normale (-8,5%), en raison des conditions de malaïgues qui ont prévalu sur l'étang de Thau. Sur les autres secteurs, les croissances sont moyennes. Les mortalités observées chez... |

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 monitoring network IFREMER /REMORA is assessing, on a yearly basis, mortality, growth and quality criteria of two oyster batches ("juveniles" = one-year old ; and "adults" = two-years old), distributed among various stations of the main French oyster areas. Samplings are carried out in March, June, September and December. This network is a tool for trend estimations (geographic and chronological, on the national scale) ; it must not be considered as an accurate estimation of professional oyster ongrowings. In 2001, mortality mainly occured in Summer on "adults" in baie des Veys (Normandy) and on juveniles in Cancale and Pénerf (Brittany) and in Fouras and Marennes (Poitou-Charentes). With an average individual weigh of 59 g in December, 2001 has been a... |

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 IFREMER/REMORA quarterly follows each year 2 batches of Pacific cupped oysters Crassostrea gigas ("juveniles"= 1 year old; and "adults" = 2 years old) on various sites among the main French oyster areas. The network monitors 46 sites, including 7 new sites added in 2003 to the network. The network REMORA thus assess seasonal survival, growth and quality of cupped oyster oysters. It is a tool for trend estimations, ecosystem management and a reference frame for scientific studies. In spite of the heat wave of the summer, rearing performances in 2003 were close to the average inter annual 1994-2003 data. The rearing yield reached 1.8 for the adults. Summer mortalities remained limited, except for juveniles in some sites (Blainville, Morlaix, Ré,... |

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.... |
