| Il y a un siècle, le savant naturaliste COSTE concevait les principes d'une technique ostréicole complète et/en faisant la démonstration pratique. Né en 1807 à Castries (Hérault), mort en 1873, Jean Coste entra à l'Académie des Sciences en 1851. Il fut également membre de l'Académie de Médicine et professeur au Muséum puis au Collège de France; il fonda le laboratoire de zoologie et physiologie maritimes de Concarneau et en fut le premier directeur. En 1892, il se vit confier la charge d'inspecteur général de la pêche fluviale et de la pêche côtière maritime. Dans le domaine qui nous intéresse particulièrement, l'ouvrage de Coste le plus fréquemment cité est le récit commenté et accompagné de suggestions qui porte sur tire : "Voyage d'exploration sur le... |

| Cette note a pour but de présenter les divers aspects du plus important centre ostréicole de France. Un court exposé sur la situation, le nombre et la superficie des terrains exploités, sur les gisements naturels, sur les collecteurs utilisés, sur les méthodes de culture de l'huître plate (Ostrea edulis) et de l'huître portugaise (Gryphaea angulata), sur les établissements d'expédition, leur nombre et le tonnage des huîtres acheminées vers la consommation, ainsi que sur les recherches effectuées par le laboratoire de l'Institut Scientifique et Technique des Pêches Maritimes, permettra de prendre contact avec la région et de mesurer les efforts déployés en vue d'utiliser rationnellement toutes les possibilités mises à la disposition de l'ostréiculture,... |

| The flat oyster Ostrea edulis L. is the indigenous oyster of the Atlantic as well as the Mediterranean coasts of Europe. Its commercial exploitation dates back to Antiquity but its breeding is now threatened by two parasitic protozoa, among which Bonamia ostreae. Various aspects of the genetics of this species' natural and farmed populations have been studied with the aid of microsatellite markers. At first, the implementation and the screening of two partial genomic libraries made it possible to identify 28 new microsatellite loci. Analysis of the segregation of 12 of these loci and of two enzymatic loci shows that most microsatellite loci are transmitted in a Mendelian way, but some loci have significant segregation distortions. Moreover, seven linkage... |

| In the scope of the study of the "on-bottom/off-bottom" mortality model in the south of the Marennes Oléron Bay, the result of the 2003 multidisciplinary study (Dynamor) appears to be the hypothesis of an acute stress, "ultimate" trigger of the mortality episodes in June. In 2004 we aim to look for the nature of this stress through the physico-chemical analysis of the sediment (Eh, pH, sulphides and ammoniacal nitrogen), the organic matter and chlorophyll load on the surface of the sediment between April and July. Herbicides are also measured in the water column, south of the bay (Seudre), during the same period. A "precocious" (around the first week of June) and "weak" (lower mortality rate on this working site since 1997) mortality peak happens when the... |

| Le banc ostréicole de Ronce-Perquis au sud du bassin de Marennes-Oléron (Charente), constitue un site atelier expérimental pour l'étude des mortalités printanière et estivale de l'huître creuse Crassastrea gigas. L'étude d'une durée de 5 mois a été effectuée sur quatre lots d'huîtres captées et élevées sur des bancs ostréicoles différents, puis placés en élevage sur un même site. Le taux de mortalité des élevages d'huîtres à plat (de 22 à 50 %) est supérieure à celle des élevages sur table (inférieure à 15 %). Le lot le plus jeune, Bartleur, qui présente une faible mortalité cumulée, résiste le mieux à la période d'acclimatation des élevages. Après une phase de "rémission" de la mortalité (mi-avril mi-mai), deux épisodes de mortalité apparaissent... |

| Les premiers résultats de nos recherches ont été exposés dans une communication au Conseil International pour l'Exploration de la Mer en 1957. Ils pouvaient être ainsi résumés : Le cycle sexuel semble être moins long pour les huîtres cultivées sur parcs que pour celles fixées naturellement sur pieux. Un même animal est vraisemblablement capable de pondre au moins deux fois pendant les mois d'été. Le volume de gonade diminue progressivement, ce qui rend malaisée la distinction des stades macroscopiques permettant une étude statistique. La taille des ovocytes diminue également pendant la saison; un nouveau matériel apparaît puis évolué (phénomènes de reconstitution permettant de prévoir des émissions tardives). |

| The artificial production of oyster spats in Japan and the USA provided inspiration to some French oyster farmers who thought that, at a time when stocking up Crassostrea gigas spats was getting more difficult, it would be interesting to try out the nutrition techniques developed by Japanese and American specialists. In this way, in La Tremblade, in the Marennes basin, M. Paul Jarno set up some structures aimed at artificial oyster reproduction. Trials started in 1968 and continued in July 1969. The first step was to assess the material and structures' usability and to take a closer look at the practical larval nutrition conditions in order to obtain fixed spats. This document is a collection of the observations carried out during the different trials. |

| Marine land-based fish farms located in coastal wetlands (salt-pond zones, lagoon banks, etc.), whether extensive or intensive, send farm effluents directly to the sea or after short periods of stocking in retention reservoirs. The aims of our investigation have been to compare the efficiency of current and potential water treatment procedures in open-air. Wastewater retention ponds in commercial farms (Atlantic coasts of France) are efficient in removing up to 1 metric ton of particulate material (dry weight) per hectare and per day (faeces and unconsumed feed), but are inefficient in reducing dissolved wastes, both organic (urea, amino acids, protein) and inorganic (total ammonia nitrogen, phosphates). Forthcoming outdoor technology to treat these forms... |

| Growth of the japanese oyster, Crassostrea gigas was monitored during 4 years, by following the recruitment of the year 1978, held in rearing conditions. After three and half years, the average length was la cm and the average total weight was 80 g. Clear seasonal changes were observed on the growth in length and weight. An important loss in dry weight occured in July, during the release of gametes. Such losses constituted 29 %, 43 % and 60 % of the dry weight, respectively for individuals which were 2 years, 3 years and 4 years old. The higher instantaneous growth rates (G) were observed during spring and at the beginning of summer. Growth model of Von Bertalanffy, gave the best estimate for the length growth of the species. During the 1979-1982... |

| Numerous diseases have been described in Ostrea and Crassostrea oysters and especially in cultivated species of commercial interest. The lack of growth, but more often mortalities, are in most cases the most obvious symptoms of this supposed sickness. The consequences of these epizooties can be so bad that they can result in the disappearance of an entire oyster population from a determined area as for Ostrea edulis L. in 1920-1921 (Dollfus, 1922) on some coasts of Europe and for Crassostrea angulata LMK in 1970-1971 on the French Atlantic coast and especially in the Marennes-Oléron and Arcachon basins. These cases can be considered as extreme cases as most of the time, oysters are only subjected to a number of episodic affections, affecting the farms only... |

| Since 1989, an homogeneous Crassostrea gigas oyster stock has been distributed once a year on several rearing sites in Brittany (3 populations per site). The main quantitative and qualitative growth descriptors, which reflect water quality effects during the monitoring period, are estimated at the end of each year. The 1989-1992 analysis prompted us to describe various growth responses correlated to biotops: oyster production in open areas influenced by oceanic waters was fairly constant in quality, including size and Polydora sp. infestation. In contrast, oysters in estuarine areas, partly affected by eutrophication (e.g., Aber Benoît, Pen Bé), or with a low carrying capacity, were characterized by weight and Polydora sp. infestation heterogeneity. These... |
