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...

Genetic improvement strategy in small aquaculture industries : the new caledonian shrimp experience
Provedor de dados: 5
Autores: Goyard, Emmanuel; Goarant, Cyrille; Brun, Pierre; Herlin, Jose; Pham, Dominique; Beliaeff, Benoit; Harache, Yves; Loubersac, Lionel; Patrois, Jacques.
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...

Sécurisation des souches de crevettes d’élevage en Nouvelle-Calédonie. Résultats de la quarantaine et du conservatoire expérimental. Eléments pour la définition d’une stratégie de sécurisation des souches de crevettes en Nouvelle-Calédonie
Provedor de dados: 5
Autores: Patrois, Jacques; Goyard, Emmanuel; Peignon, Jean-marie; Dufour, Robert; Ansquer, Dominique.
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.

Pearl formation: Persistence of the graft during the entire process of biomineralization
Provedor de dados: 5
Autores: Arnaud, Sophie; Goyard, Emmanuel; Vonau, Vincent; Herbaut, C; Prou, Jean; Saulnier, Denis.
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...

Autores: Goyard, Emmanuel.
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,...

Autores: De Lorgeril, Julien; Gueguen, Yannick; Goarant, Cyrille; Goyard, Emmanuel; Mugnier, Chantal; Fievet, Julie; Piquemal, D; Bachere, Evelyne.
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...

Programme qualité des huîtres creuses Crassostrea gigas : 1ère année (1995)
Provedor de dados: 5
Autores: Baud, Jean-pierre; Goyard, Emmanuel.
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.

Genetic structure at different spatial scales in the pearl oyster (Pinctada margaritifera cumingii) in French Polynesian lagoons: beware of sampling strategy and genetic patchiness
Provedor de dados: 5
Autores: Arnaud, Sophie; Vonau, Vincent; Rouxel, Catherine; Bonhomme, Francois; Prou, Jean; Goyard, Emmanuel; Boudry, Pierre.
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...

Residual genetic variability in domesticated populations of the Pacific blue shrimp (Litopenaeus stylirostris) of New Caledonia, French Polynesia and Hawaii and some management recommendations
Provedor de dados: 5
Autores: Goyard, Emmanuel; Arnaud, Sophie; Vonau, Vincent; Bishoff, Vincent; Mouchel, Olivier; Pham, Dominique; Wyban, Jim; Boudry, Pierre.
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...

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.

Gestion des ressources génétiques de l'huître perlière Pinctada margaritifera de Polynésie française : caractérisation génétique des populations et optimisation du recrutement pour l'exploitation perlière
Provedor de dados: 5
Autores: Arnaud, Sophie; Goyard, Emmanuel; Prou, Jean; Vonau, Vincent; Bonhomme, Francois; Boudry, Pierre.
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...

The tropical seabass Lates calcarifer was introduced in Tahiti in 1984 and then was domesticated without other introduction. Three successive generations have been obtained in captivity. Tissue samples of the 38 animaIs which represent the total Tahitian broodstock were preserved in alcohol to be genotyped with four microsatellite markers (Yue et al., 2001). Three of four described markers were successfully transferred to the laboratory of genetics of Tahiti (marker LcaM01, LcaM02, LcaM03), as the revelation technology available locally did not allow the use of LcaM04 in routine. The results show that the genetic diversity of the tahitian broodstock is not equivalent of the one of the species, which could be explained by the small size of the founder...

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.

Peneid shrimp are commonly reared in clear-water aquaria or tanks for short-term studies of 4-6 weeks during controlled experiments, such as nutrition studies to estimate dietary nutrient requirements. Recently, in line with the genetic program at Centre Oceanologique du Pacifique (COP), experimental clear-water facilities were tested for the first time over a longer rearing period. Environmental conditions used to maintain animal growth in clear-water system using a well-balanced diet were defined. After 100 days, shrimp growth rates tended to decrease and only by adjusting the diet could shrimp complete their life cycle and reach maturation size of around 40 g. This paper presents information on stocking density, diet quality and husbandry linked to...

Selective breeding of shrimp for viral resistance is established for species like L. vannamei and L. stylirostris. However, selection for bacterial infection resistance is not documented. In New Caledonia, "Syndrome 93" is a vibriosis that affects cultured shrimps during the cool season with survival from 15 to 30%. Current practises for breeders rearing at low densities do not improve the resistance of the offsprings mainly because selection pressures for "Syndrome 93" are low. Even after the fifth generation, survival improvement is not significant.

Autores: Lapegue, Sylvie; Bedier, Edouard; Goyard, Emmanuel; Degremont, Lionel; Baud, Jean-pierre; Gerard, Andre; Goulletquer, Philippe; Boudry, Pierre.
Two oyster species are currently present along the French coasts : the indigenous European flat oyster (Ostrea edulis), and the Pacific cupped oyster (Crassostrea gigas), that has been introduced from Japan since the beginning of the 70ies. The flat oyster successively suffered from two protozoan diseases during the 60ies and its production decreased from 20 000 tons/year by that time to 1 500 tons/year nowadays. Consequently, the oyster production is principally (99%) based upon the Pacific oyster species with approximately 150 000 tons/year among which 90% are grown from the natural spat.

Depuis de nombreuses années, les biologistes étudiant des poissons d'eau douce, ont mis en évidence les relations existant entre le cycle de maturation et les facteurs environnementaux tels que la température et la photopériode (Bullough, 1940 ; Merinan &amp; Schedl, 1941 ; Harrington 1957, Henderson, 1963...). En aquaculture, pour des espèces tempérées comme le loup, la dorade, le turbot, dès 1973, l'opportunité du décalage de la saison de ponte grâce au raccourcissement des cycles environnementaux naturels, est démontré (Girin &amp; Devauchelle, 1978). Sur le loup (Dicentrarchus labrax), des pontes décalées ont pu être obtenues par manipulation du seuil facteur est également reprise par Suquet (1987) puis par Bouget (1988), sur la dorade (Sparus aurata)....

Autores: Soletchnik, Patrick; Goyard, Emmanuel; Thouard, Emmanuel.
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 (Sciaenosp 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 grâce au contrôle environnemental de la température et de la phtopériode. 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, 9 000 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...

What is REMORA? REMORA &amp;#8722;REseau MOllusques du département Ressources Aquacoles&amp;#8722; (Aquaculture Resources Department Mollusc Network) is a surveillance network dedicated to the growth of hollow oysters Crassostrea gigas. In the past and in most production areas, observations were made on a regular basis. In 1993, homogenising experimental protocols between the different laboratories involved was decided, as well as using a common initial oyster batch, therefore organizing a network covering all of the French coasts. This network aims at providing, each year, the production's basic characteristics found in main oyster beds (growth reference). It also better characterizes variations and shows potential tendencies.

The network IFREMER/REMORA has watched every year, since 1993, from February to December, mortality, growth and quality criteria of two oyster class-size ("juveniles" of the first-year c1ass and "adults" of the second year c1ass), distributed among various stations of the French oyster areas. This has provided a quite standard and simple annual assessment of the rearing results, generally tallied with professional observations. From year to year, data series have been obtained, from which mean values (references), chronological trends or spatial differences can be analysed. Results in Brittany, from 1993 to 1998, show that, in a "normal" year, 30 g oysters grow to 60-80 g at the end of the year, with a mortality rate of 10-15%. Mortality occures mainly in...

The Pacific blue shrimp Litopenaeus stylirostris was introduced in New Caledonia thirty years ago. Because of its high inbreeding, a SPF strain domesticated in Hawaii, genetically differentiated from the Caledonian strain, had to be imported. The two strains’ reproductive performances were compared at different periods and cross breedings were assessed. The average results show that Caledonian animals give twice as many nauplii than the Hawaiian animals. The best cross breeding is obtained with Caledonian male x Hawaiian female. A possible explanation is the later age or weight of maturity for the Hawaiian strain compared to the Caledonian strain, difference which could come from the geographical origins and/or the zootechnical and climatic domestication...

Les objectifs pour l'année 1997 étaient les suivants : • Poursuivre les premières reproductions des espèces pour lesquelles nous disposons de géniteurs GO. L'objectif est toujours de limiter le stockage d'animaux importés en produisant une descendance simultanément à des témoins C. gigas qui serviront de comparaison. • Tenter des hybridations inter-spécifiques des différents taxons présents au sein du conservatoire en fonction des connaissances disponibles dans la littérature sur ce sujet (voir pour revue Gaffney et Allen, 1993). • Importer de nouvelles souches ou espèces. Élargir la gamme des espèces présentes au sein du conservatoire de souches (les capacités d'accueil de la salle de quarantaine étant limitée).

Autores: Soletchnik, Patrick; Goyard, Emmanuel; Thouard, Emmanuel.
Aux USA, et plus particulièrement en Caroline du sud, l'étude de la croissance de l'ombrine, a commencé dès 1947, à partir des populations naturelles retenues dans les marais salants (Lunts 1951, d'après Smith et al, 1985) puis se sont poursuivies (Theling and Loyacano 1976), également en Louisiane (Beckman et al, 1988 ; Boothby et Avault, 1971 ; Bass et Avault, 1975). En élevage, très peu de données existent sur les performances de croissance de cette espèce jusqu'à une taille commercialisable. Hopkins et al, (1987) fait part de quelques résultats en bassin de terre. Peu de travaux existent sur les besoins alimentaires de l'espèce (Daniels et Robinson, 1986 Williams et Robinson, 1988, Robinson, 1988). Dans le cadre du programme de mise au point technique...

Two batches of red drum larvae were air shipped from hatcheries in the U.S.A. and stocked in two intensive tank experiments at densities oc 7 :.nd 2-3 larvae per liter. Food items include live rotifers, copepods, brine shrimps. squid and commercial fish pellets. Growth rates were similar in both experiments up to day 20 (12-1" mm) but differences in feeding schedules and an infestation by the dinoflagelate Amyloodinium sp. affected the growth from day 20 to 43 in the second trial. Significant mortalities occurred in the tanks during the first feeding period (days 2 to 7) and again from days 17 to 20 as the result of cannibalism. Survival between day 2 and day 44 was 44% in the first trial. Abnormal inflation of the swim bladder and infection with...

The New-Caledonian shrimp industry is based on the controlled reproduction of the shrimp Litopenaeus stylirostris, a species which was introduced in the 80s. The major difficulty to which the industry has been faced for 10 years is the occurrence of the "syndrome 93", which corresponds to mortality phases when the temperature falls down in April-May-June. This mortality is associated to the pathogenic bacteria Vibrio penaecida and is expressed at different levels which are variable from year ta year and from pond to pond. No resistance to this pathology has been developed spontaneously. This is likely due to the protocole used to rear spawners, which does not allow to implement an efficient selective pressure at each generation  An experimental selection...

Le programme de sélection de l'huître plate a été initié en 1985 par des pathologistes de la Tremblade. La sélection ne portait que sur le seul critère de tolérance des huîtres plates au parasite Bonamia ostreae et correspondait plus à un outil pour étudier divers aspects de la parasitose qu'un un programme d'amélioration génétique visant la relance de la culture de l'huître plate. Dans le cadre du réseau REGEMO, ce programme a ensuite été repris par les généticiens de l'Ifremer : 1) rappel historique et définition d'un vocabulaire commun à l'ensemble des membres du réseau REGEMO. 2) Inventaire et bilan des opération menées ou en cours ( sur la dernière génération de sélection produite ne 1995, sur le matériel issu de cette génération et produit en 1997....

Two populations of the Latin American shrimp Penaeus (Litopenaeus)stylirostris domesticated in Hawaii and in New Caledonia were previously shown to be genetically differentiated and proven highly inbred. In New Caledonia, where different Vibriosis affect shrimp production and antibiotic use is banned in growing ponds, the Hawaiian population was introduced to increase the allelic variability available for local shrimp farmers and start a genetic improvement program. Growth and survival rates of the two pure populations and the two-way F-1-hybrids obtained by breeding Hawaiian animals with New Caledonian animals were assessed in several simple experiments (earthen ponds, floating cages and experimental infection challenges) during two years on two...

L'amélioration des performances de l'huître plate européenne Ostrea edulis par la sélection génétique

The European flat oyster Ostrea edulis has been considered as the traditional French oyster for a very long time and has now nearly disappeared from our farms, as a consequence of the two successive epizootic of the Marteilia refringens parasite and Bonamia ostreae. The actual quasi monoculture of Crassostrea gigas has made necessary the search for a diversification in oyster culture, including the search for a new start of the indigenous flat oyster culture. The Ifremer has been conducting parallel works since 1985 in order to better understand the biology of the parasite as well as to try and select different lines of flat oyster resistant to Bonamia ostreae.
