| As of 1985, Ifremer set up a selection programme for resistance to the protozoan Bonamia ostreae in European flat oysters (Ostrea edulis). Two selection lines, L85 and L89, from the third and second generation, respectively, were produced with 17 and 21 different families. The experimental design also included a mixed line (L85 x L89) of seven families and a control line of five families from Quiberon broodstock maintained without selection pressure. |

| New Caledonian shrimp farming feasibility studies started in the mid-seventies. Today ca. 2000 tons of Litopenaeus stylirostris, introduced in 1978, are semi-intensively produced each year. Since fifteen years, production has been impacted by two seasonal vibriosis, the “Summer” syndrome caused by Vibrio nigripulchritudo in relation to pond bottom and water column quality, and the “Winter Syndrome” caused by Vibrio penaeicida in relation to drastic temperature drops . With the ambition of elucidating processes possibly leading to mortality outbreaks in ponds, Ifremer has been conducting a research program since 2003 under the DESANS project (2003-2006) and the present DEDUCTION project, equally funded by the South and North Provinces and by the Government... |

| Shrimp farming in New Caledonia relies on the culture of a domesticated strain of Litopenaeus stylirostris introduced from Mexico at a time when genetic principles were of little or no consideration. Since then, advances in agriculture and for some aquatic species of importance led caledonian shrimp farmers to reconsider the appropriateness of a genetic improvement strategy adapted to local biotechnical and economical constraints. This questioning involves many different and interrelated aspects: scientific and technologic (genetics, biosecurity, quarantine, ), economic and organizational (financing, diffusion of genetic improvement) and pedagogic (awareness of farmers). Local institutions, producers associations, research centre and sanitary services... |

| L'aquaculture en Martinique commence dans les années 1970 avec le transfert technologique de l'élevage de la chevrette : Macrobrachium rosenbergii. Au début des années 1980, le CNEXO en collaboration avec une association régionale (ADAM) travaille aux Antilles à la sélection d'espèces tropicales de poissons. Cette étude s'inserre alors dans un programme international de sélection d'espèces tropicales, coordonné par le Centre Océanologique du Pacifique. En début d'année 1987, après une étude prospective d'investigation aux USA, L'IFREMER Martinique initie le programme d'étude de la mise au point technique de l'élevage de l'ombrine en conditions intensives ... |

| A new strain of L. stylirostris was introduced in New Caledonia. Quarantine facilities were set up inland using RAS and artificial seawater. After 5 months of rearing, all the 16 initial families were still represented with a 50% average survival. Three samplings for known pathogens were made during that period, all of them negative. Half the animals were taken to outdoor ponds for rearing to reproduction size when the rest was used to test different arrangements for a biosecure rearing until reproduction. Numerous spawnings and nauplii were obtained but larval rearings could not be completed. Different options are considered for the set up of a biosecure facility allowing the rearing and the breeding of pathogen free strains of shrimp. |

| Depuis maintenant plus de trois ans, l'équipe IFREMER de Martinique travaille à la mise au point technique de l'élevage de l'ombrine subtropicale (Sciaenops ocellata), dans des conditions intensives. En matière de reproduction, l'équipe IFREMER a engagé dès 1987, une opération de transfert de la technologie Américaine de maturation et ponte grace au contrôle environnemental de la température et de la photopériode. Près de 50 millions d'oeufs ont été produits en 1989, à partir de 5 femelles de 5 à 6 kg. En terme d'alevinage, les "résidus d'expérimentation", ont été de 12.000, 18.000, 9.ooo et 89.000 alevins sevrés (1 à 2g), respectivement pour les années 1987, 88, 89 et 1990. En 1990, l'objectif principal de démonstration de la faisabilité de la technique... |

| Most bivalves species of the genus Pinctada are well known throughout the world for production of white or black pearls of high commercial value. For cultured pearl production, a mantle allograft from a donor is implanted into the gonad of a recipient oyster, together with a small inorganic bead. Because of the dedifferentiation of cells during the first steps of the host oyster's immunological reaction, so far the fate of the graft and its exact role in the process of pearl formation could not be determined via classical histological methods. Here we report the first molecular evidence of the resilience of the graft in the recipient organism by showing that cells containing genome from the donor are still present at the end of pearl formation. These... |

| 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,... |

| Understanding of antimicrobial defence mechanisms of penaeid shrimp should help in the design of efficient strategies for the management and disease control in aquaculture. In this study, we have specifically analysed the expression in circulating hemocytes of antimicrobial peptides (AMPs) encoding genes, such as PEN2 and PEN3, ALF, crustin, lysozyme and a putative cysteine-rich peptide. We evidenced a relationship between the level of expression of some AMPs and the successful response of the shrimp, Litopenaeus stylirostris, to circumvent a pathogenic Vibrio penaeicida infection. Additionally, significant differences in some AMP transcript amounts are evidenced between control, non-selected shrimp line and the third generation breeding of shrimp selected... |

| Variability of oyster quality at marketable size in winter was assesed by using a proportional sampling strategy based upon the yearly production of the oyster packing house. Landings per unit of production were estimated using the number of commercialized sanitary certification labels or/and the annual landings declared to the Veterinary Services. The range of variability for 15 parameters was estimated using the national monitoring network (REMORA) data outputs and a regional questionnaire. Both data sources showed similar results. Condition indices and morphological factors led to the highest variability. However, these conclusions should be confirmed by additional studies considering seasonal trends to assess the described quantitative relationships. |

| In order to study further the genetic structure of the pearl oyster Pinctada margaritifera in French Polynesia with a special consideration for the sampling scale, we analyzed or re-analyzed sets of data based on nuclear DNA markers obtained at different spatial scales. At a large scale (several 1,000 km), the remote Marquesas Islands were confirmed to be significantly differentiated from Tuamotu-Gambier and Society archipelagos, with a marked difference however for the two main islands that are different from each other. At a medium scale (several 10 to several 100 km), overall homogeneity was observed within and between these two archipelagos, with some exceptions. This could be attributed both to large-scale larval dispersal and to human-driven spat... |

| Pendant l'été 1995, des mortalités d'huîtres creuses ont été observées sur une grande partie du littoral français et notamment en Bretagne. Pour cette région, un ensemble d'informations concernant ces mortalités a été recueilli au près d'organismes en contact direct avec les professionnels : IFREMER, les Affaires Maritimes et la Section Régionale Conchylicole de Bretagne sud. L'objectif de ce rapport est, à partir de quatre sources d'informations, de chiffrer ces mortalités dans les différents sites bretons et d'étudier les relations éventuelles avec différents paramètres tels que l'origine des huîtres, la technique d'élevage, le site d'élevage, etc... Des comparaisons sont faites avec les résultats d'enquête réalisée en Normandie (IFREMER... |

| The Latin American shrimp Litopenaeus stylirostris was introduced in three different Pacific islands (Tahiti, New Caledonia via Tahiti, and Hawaii) and hatchery-propagated for 7-25 generations to develop shrimp farming based on these domesticated stocks. Three microsatellite markers have been used in an attempt to assess the genetic bases of the populations available to start a selective breeding program. The comparison of eight hatchery stocks (five New Caledonian, two Hawaiian and one Tahitian stocks) and one wild Ecuadorian population showed a much lower variability in the domesticated stocks than in the wild population, especially in New Caledonia and Tahiti (2-3.7 vs. 14-27 alleles per locus; 20-60% vs. 90% expected heterozygosity). The Tahitian and... |

| La première illustration d'une larve d'ombrine dans le milieu naturel est publié par Jannke en 1971. La description des oeufs et larves d'ombrine est réalisée par Holt (1981) . L'alimentation des larves d'ombrine dans le milieu naturel est précisée par Steen et Laroche (1983), (d'après Robinson, 1988). La croissance larvaire dans le golfe du Mexique est étudiée par Comyns et al, 1989. En 1978, Arnold et al., avec les premiers résultats obtenus sur le contrôle de la ponte de l'ombrine, effectuent les tous premiers essais d'élevage en intensif dont les résultats sont peu prometteurs par rapport à ceux obtenus d'après la technique d'élevage larvaire en extensif (Colura et al.,1976). Par la suite un certain nombre de paramètres de l'élevage en bassins vont... |

| The Aquaculture and Pathological Genetics (GAP) laboratory at La Tremblade has been monitoring three populations of European flat oyster since 1985 or 1989 under selection for higher survival rates in the presence of the parasite Bonamia ostrea. One selection cycle (1985 population) or two (1989 populations) were carried out by mass selection by placing the oysters for several years in a highly infested zone, and then harvesting spawns from survivors. |

| Exploitation of the pearl oyster Pinetada margaritifera, which has developed in French Polynesia over the last twenty years, is based mainly on the collection of natural spat. Recruitment is highly variable in space and time and so spat is very often transferred by the farmers between atolls or even between archipelagos. In previous studies, anonymous nuclear markers demonstrated that This development has coincided with a genetic homogenisation of the wild stocks since the 1980s. This suggests a high level of reproductive success on farms, which is likely to be due to the high density of animaIs when compared to the density in the wild. We used the same markers to show that the level of genetic variability observed on farms is not significantly different... |

| Le travail présenté reprend les principales expérimentations menées en structures de petits volumes (40, 120 et 150 l). Elles ont permis de lever un certain nombre de points de blocages au cours de ces 3 années d'études. Les résultats de ces expérimentations menées en réplicats de 3 à 7 bassins par condition étaient immédiatement pris en compte dans les élevages "pilotes" menés parallèlement. Vingt-deux expérimentations ont été réalisées au cours de différentes phase de l'élevage, sur des thèmes aussi divers que la lumière, l'abondance et la qualité des proies, le sevrage précoce, le sevrage, les normes zootechniques eu prégrossissement. Ces résultats sont présentés dans ce 4ème document de la mise au point de l'élevage de l'ombrine subtropicale. |

Par le principe même du réseau REMORA, l'intérêt de ces résultats réside dans la possibilité de comparer les sites entre eux et les années entre elles en s'affranchissant des variations de pratiques culturales locales (variations de dates de mise en élevage, origine différentes de naissain, etc.. .) ainsi que des contraintes réglementaires liés aux schémas de structures départementaux.
