| Dans le cadre d’un réseau national (VELYGER), la Baie de Bourgneuf (partie Nord de la Baie) a fait l’objet en 2009 d’un suivi détaillé de la reproduction de l’huître creuse, Crassostrea gigas : gamétogenèse et ponte des adultes, abondance et développement larvaire ainsi qu’intensité et survie du captage sur collecteurs. Les résultats de ce suivi ont été mis en ligne, sous la forme de bulletin hebdomadaire, en temps quasi-réel sur le site : http://www.ifremer.fr/velyger. Il ressort, en 2009, que : (1) la gamétogenèse des huîtres s’est déroulée favorablement en permettant une ponte massive dans la première quinzaine de juillet, plus précoce mais aussi plus importante que sur des sites traditionnels (Arcachon et Marennes-Oléron) ; (2) les larves ont été... |

| 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... |

| 1. Introduction: network organisation in 1997. The REMORA network - REseau MOIIusques du département Ressources Aquacoles de l'Ifremer - (Ifremer's Aquaculture Resources Department Mollusc Network) has been evaluating, since 1993, hollow oysters' growth (Crassostrea gigas) in major French oyster beds. In order to do so, it has followed up on a yearly basis the growth of a unique oyster batch shared among different stations in the main French raising areas. Releasing takes place in February and picking happens in November or December; intermediary sampling is done in June and September. All operations happen on the same dates for all stations. A national report is published each year. 'Regional' stations are sometimes added to the national network, but they... |

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 is assessing on a yearly basis, from February to December, mortality, growth and quality criteria of two oyster batches ("juveniles" = one-year class ; and "adults" = two-years class), deployed among various stations of the main French oyster areas.

Based on REMORA results, generally tallied with professional observations, 1998 on the whole was a second year of low mortality.

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... |

| 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,... |

| The network REMORA by IFREMER 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 monitored 46 sites in 2004, including the 7 new sites added in 2003. The network REMORA thus assess seasonal survival, growth and quality of cupped oysters. It is a tool for trend estimations, ecosystem management and a reference frame for scientific studies. Globally speaking, the year 2004 was a good year for oyster farming, with a low mortality and a fast growth. The rearing yield (survival x growth) reached 2.0 for adults instead of 1.8 usually. However, the meat index remained close to the average inter annual data.... |

| 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... |

| La situation épidémiologique de la maladie de l'anneau brun et accessoirement les croissances et mortalités observées dans le cadre du réseau de suivi des élevages et gisements naturels de palourdes, en Bretagne, en 1991 sont présentées. En élevage, la situation demeure assez contrastée avec une majorité de semis faiblement infestés (moins de 20 % d'anneaux bruns) et quelques semis fortement atteints, soit en secteurs sensibles (Brouennou, Finistère) soit à la suite de transferts de juvéniles de gisements naturels (Morbihan). Ces gisements naturels sont en majorité contaminés, à des taux faibles (inférieurs à 10 %). |
