| La conchyliculture, et principalement l’élevage de l’huître creuse, Crassostrea gigas, constitue la principale activité aquacole française. Cette activité repose, en grande partie, sur le recrutement naturel de l’espèce qui assure 70% des besoins en jeunes huîtres (naissain) : cette activité de collecte s’appelle le captage. Les deux principaux centres de captage en France sont les bassins d’Arcachon et de Marennes-Oléron. Or, depuis une dizaine d'années, sur le bassin d'Arcachon, le captage devient très variable: à des années de captage nul (par exemple les années 2002, 2005, 2007) ou faible (2009, 2010, 2011) succèdent des années excellentes voire pléthoriques (les années 2003, 2006, 2008). A Marennes-Oléron, cette variabilité existe, même si elle est... |

| 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 study is the second part of a former report rapport Ifremer DRV/RST/RA/LCB/2002-08 dealing with rearing methods, growth and mortality performances, and problems encountered by the oyster farmers from Quiberon Bay (2800 ha of leases) : the first report relied on a survey achieved in july 200l, about 18 oyster farmers, and 2 diving campaigns (july and october 2001) on 2 years old oyster batches from the same farmers. Il is now completed by a last campaign of diving in october 2002, on 7 parcels out of the 18, still bearing the initial oysters. The analysed enterprises vary in particular by the location and depth of their concession inside the bay, but also by their rearing scheme : a majority favours seedings with 18 month old oysters or more, according... |

| 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... |

| A new process of collecting fIat oyster spat in deep water, based on the use of suspended mussel shell, was perfected between 1978 and 1982. The technique has contributed the continued breeding of the species in Quiberon bay (Brittany ) , in spite of the presence of Bonamia ostreae. In order to quantify the number of spat recruited by this technique each year, a method of estimation was tested during the summer 1985. This paper describes the sampling strategy and the results. |

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... |

| This fifth part of the polyploidisation program reports the experiments that were conducted in 1993 and that were devoted to : - monitoring growth performance of Ostrea edulis diploids and triploids in La Trinité sur Mer and Palavas - monitoring growth performance of Crassostrea gigas diploids and triploids in Port en Bessin, Marennes Oleron (2 locations), Arcachon and Palavas - comparative study of gametogenesis for C. gigas diploids and triploids - comparative study of C. gigas diploids and triploids using sensorial analysis At the end of fifth year, it was clear that triploids are advantageous although such a statement must be moderated according to locations. The gametogenesis stydy showed that triploidy is associated with partial to complete... |

| 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 %). |

| Summer mortalities of young oysters have been studied in 1999 through the monitoring of a unique oyster batch distributed among 3 sites located from upstream of an estuary (Fort-Espagnol, Auray river) to downstream (Kerpenhir, Auray river) up to open bay (Men er Roué, Bay of Quiberon). Mortality and growth have been monitered in parallel with vitality indices, so as to try or identify periods of weakness of oysters. The spat grew from a mean weight of 3 g, in the beginning of May to around 35 g in November, without sharp differences between sites. The summer mortalities remained moderate (10 %) in the 2 most marine stations, whereas a light peak of mortality (15 %) was recorded in July in the most continental station. Any of the physico-chemical parameters... |

| Mussel samples have been placed in plastic-mesh bags hung on wood poles (« bouchots »), at 4 locations of a mussel culture area in the bay of Vilaine (South Brittany, France). They have been monitored for one year, from February 2000 to February 2001. The recorded growth have been rather fast (plus 1.2 g per month between April and September), and mortalities moderate (between 15% to 25%), with better results in southern stations, further from the estuary. Among the physico-chemical parameters recorded, the most striking were very low salinities (below 10 g/l) recorded for days, after heavy rains. They provoqued a valve closure of mussels (recorded by a « valvometer »). Some physiological indicators being tested (muscle force and hermeticity) seemed to... |

| 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... |

| Depuis 2009, l'Observatoire Conchylicole assure le suivi, sur des sites ateliers disposés sur l'ensemble du littoral français, de lots sentinelles d'huîtres creuses Crassostrea gigas représentatifs de la production française. Leur suivi permet d'acquérir des données nationales de croissance et de mortalité, de traduire la dynamique spatio-temporelle des performances d’élevage et ainsi de participer à la compréhension des phénomènes observés. Pour ce faire, des lots sentinelles d’huîtres correspondant à différentes origines (captage ou écloserie, diploïdes ou triploïdes) et à différents stades d’élevage (naissain ou adultes 18 mois) sont déployés simultanément sur 13 sites ateliers représentant les grandes régions conchylicoles du littoral français.

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 mise au point et le développement de techniques de captage en milieu naturel et de production en milieu contrôlé permettent d'envisager pour la coquille Saint Jacques une aquaculture extensive du type de celle réalisée pour l'huître sur parc non découvrant : un ou plusieurs centres favorables à la collecte du naissain pourvoient en juvéniles des secteurs propices à l'élevage. Une plus value marchande peut être obtenue lorsque le changement de milieu s'accompagne de modifications physiologique ou organoleptiques. Ainsi, la présence de la glande génitale développée (ou corail) est particulièrement appréciée du consommateur français. Cet état s'observe tout au long de l'année sur les gisements de Bretagne Sud et de Rade de Brest alors qu'en Baie de Saint... |

| The Aquaculture Resources Department's mollusc network (REMORA) federates six coastal Ifremer laboratories. Since 1993, REMORA has implemented a unique national protocol to account for the variability in the growth of Pacific oysters farmed in 39 sites within the main production areas, from Normandy to the Mediterranean Sea. In 1995, the goal of the network was expanded to include monitoring of a second age class. To do so, the protocol developed for adults was adapted to monitor juveniles. The data, organised in Excel worksheets with a specific application written in Visual Basic, allows for inter-station and inter-annual comparisons and thereby constitutes a database of interest to oyster farmers, scientists and administrative personnel. |
