Accumulation de Fe, Cu, Zn, Mg, Mn et Co dans l'ovaire de Carcinus maenas L. au cours de l'ovogenèse ArchiMer
Martin, Jean-louis.
During ovogenesis the ovary of Carcinus maenas shows a continuous accumulation of Fe, Cu, Mg, Mn and Co. For Zn the accumulation seems to stop for gonad indexes near 6.5. The goal of this accumulation is not determined. Nevertheless we suppose that it is in relation with the role of organic reserves that possess the female sexual cells in decapods and with the synthesis of enzymes and hemocyanin.

Bases génétiques et plasticité de la croissance et de la survie chez l'huître creuse, Crassostrea gigas ArchiMer
Ernande, Bruno; Boudry, Pierre; Heurtebise, Serge; Haure, Joel; Martin, Jean-louis.
Growth and survival are the two most interesting characters for oyster farming as they determine the biomass produced in the farms (growth x survival). Thus, a selection program aiming at improving these two characters could be of a great help. However, the oyster, as a sessile organism, is influenced by environmental variability (spatial and temporal) either natural or caused by the used oyster culture methods. Submitted to this variability, oysters must have evolved so as to adapt (short term) to this environmental variability.

The REPAMO network (network ofmollusc pathology), created in 1986, ensures the survey of shellfish health status along French coasts according? to European Directives 91/67/EEC and 95/70/EEC. The aims of the network are 1 - to prevent the introduction and spread of exotic pathogens, 2-to study the means to decrease the impact of pathogens already present and to survey their evolution. In 2003, the REPAMO network focused on the survey oflisted diseases (bonamiosis and marteiliosis) in two areas under agreement process (Banc de Granville and zone X) and on the study of abnormal morlalities. Number of reported abnormal morlalities has increased in 2003. This rise can be partly explained by the recent network restructuring, but also by the summer heatwave and...

Characterization of summer mortalities of C. gigas oyster in France in relation to environmental parameters ArchiMer
Soletchnik, Patrick; Ropert, Michel; Bedier, Edouard; Costil, K. S.; Dubois, Brice; Degremont, Lionel; Bouget, Jean-francois; Martin, Jean-louis; Enriquez-diaz, M.; Faury, Nicole; Le Moine, Olivier; Renault, Tristan; Gagnaire, Beatrice; Huvet, Arnaud; Moal, Jeanne; Samain, Jean-francois.
Field characterization of summer mortality was performed in France in the frame of the Morest project. Natural and hatchery spat were compared between three oyster production areas in France. Regardless of the natural or hatchery origin, oysters died during the reproduction period after temperature reaches 19 degree C. Thus, in southern areas, temperature accelerated gametogenesis of small spat (10mm) as well as adults, and mortality appeared for the two age classes. In contrast, sexual maturation proceeded more slowly in northern where spat mortality was lower compared to 18 months old oysters. However, critical gametogenesis and temperature were not sufficient to induce mortalities, as observed in examples with stable environment. Alternatively sediment...

Could a diet enriched with n-3 highly unsaturated fatty acids be considered a promising way to enhance the immune defences and the resistance of Penaeid prawns to environmental stress? ArchiMer
Chim, Liet; Lemaire, Pierrette; Delaporte, Maryse; Le Moullac, Gilles; Galois, Robert; Martin, Jean-louis.
The prawn Penaeus stylirostris (Stimpson), when fed for 28 days with n-3 highly unsaturated fatty acid (HUFA)-enriched feed pellets, demonstrated an enhanced resistance to variations in environmental parameters (a decrease in temperature and salinity over a 4-day period from 28 degreesC to 17 degreesC and from 35 parts per thousand to 10 parts per thousand respectively) and an improvement in their immune defence potential, i.e. increased agglutination titre of plasma and increased respiratory burst of haemocytes.

Détermination de la pollution chimique des baies de Jakarta, Banten, Cilacap (Indonésie). Hydrocarbures, organochlores, métaux ArchiMer
Martin, Jean-louis; Marchand, Michel; Le Guellec, Anne-marie; Caprais, Jean-claude.
Analyses of pesticides, polychlorobiphenyls (PCB's) and hydrocarbons have been carried out in sediments and water samples from the bays of Jakarta, Banten and Cilacap. Heavy metals (Hg, Cu, Mn, Zn, Fe, Pb, Cd, Ni, Co and Cr) have been analysed in sediment samples fram the same areas. - Organic pollutants : The results show that for pesticides, PCB and hydrocarbons, in water and in sediments, there is no significant pollution for the bays of Banten, Cilacap and Jakarta. The bay of Banten, where most of the concentrations are under the detection limits, that is ta say 2 ug/kg for the sediment and 2 ng/1 for the sea water, can be considered as a reference area. For total hydrocarbons and DDT, the bays of Cilacap and Jakarta show concentrations which can be...

Effets d'un mélange de pesticides sur les hémocytes d'huître creuse, Crassostrea gigas. ArchiMer
Gagnaire, Beatrice; Geret, Florence; Haure, Joel; Martin, Jean-louis; Burgeot, Thierry; Thomas-guyon, Hélène; Renault, Tristan.
Shellfish industry is often realised in estuarine areas, subjected to pollutions due to agricultural activities. The harmful effects of pesticides on animals inhabiting these estuarine zones are poorly documented. Bivalve molluscs represent an interesting model because they are sedentary and they filter water intensively. Effects of pesticides on haemocytes functions were tested in Pacific oyster, Crassostrea gigas and analysed by flow cytometry. A combination of pesticide at environmental concentrations was tested in vivo. Animals used corresponded to two genetically selected populations produced in hatchery.

Effluents from land based marine farms: nature, treatment, valorisation, modelisation. Applications to fish and shrimp rearing ArchiMer
Hussenot, Jerome; Lefebvre, Sebastien; Martin, Jean-louis.
Fish culture (seabass, turbot...) on the French metropolitan coast, and shrimp culture in the overseas territories (essentially New Caledonia and Tahiti) are subject to a regular development through land based farms. Three thematic of research on aquaculture ponds are carried out in CREMA-L’Houmeau, in collaboration with producers. The aim of the first one is to determine the optimal rearing conditions (stocking density, water renewal rate, input of oxygen, rate of feeding...) which allow to minimise the quantity of wastes for a similar final biomass. The second part aims to reduce the nutrient loading in the effluent, through open-air treatments: sedimentation ponds, foam fractionation, mass production of phytoplankton, and rearing of molluscs on the...

Elevage de crevettes en cage - Rapport final ArchiMer
Martin, Jean-louis; Paquotte, Phillipe; Barthelemy, Patricia.
Les expériences d'élevage de crevettes en cage au Brésil ont été initiées par Eduardo LEMOS en 1985 à "Barra de Guaratiba" dans l'Etat de Rio. Les premiers résultats encourageants conduisaient, en 1988, l'inventeur du projet à créer, en association avec la société KIEPPE investimentos, une entreprise "Litoral Sul Maricultura (LSM)" pour développer la technologie commerciale d'élevage de crevettes en cage. C'est cette même année que LSM construisait la station pilote située dans l'Etat de Bahia au village de Barra do Serinhaém, dans le canton d'Itubera

Estimation de stocks d'huîtres sauvages sur les zones concédées de la partie vendéenne de la Baie de Bourgneuf en 2003 ArchiMer
Martin, Jean-louis; Haure, Joel; Dupuy, Beatrice; Nourry, Max; Palvadeau, Hubert; Papin, Mathias; Penisson, Christian; Thouard, Emmanuel.
Au cours des dernières années, les résultats du réseau REMORA montrent un déficit de croissance des huîtres en baie de Bourgneuf par rapport à la moyenne nationale. Ce déficit de croissance s'accentue particulièrement en 2000 et se poursuit en 2002. L'une des hypothèses pouvant être mise en avant pour expliquer les causes de ce manque de croissance est la biomasse accrue des organismes filtreurs cultivés ou non: huîtres, moules, crépidules. Afin d'avoir une vision globale du fonctionnement de l'écosystème de la baie, il est nécessaire d'étudier l'importance relative de ces différents stocks de coquillages.

La baie de Bourgneuf est un bassin de 34000 ha dont l'activité ostréicole représente à elleseule plus de 95% du chiffre d'affaire local réalisé par la production conchylicole. Lesdifférentes études qui ont été réalisées ont montré que le stock d'huîtres en élevage (40000t) et la production annuelle (13000 t) qui en est issue variaient peu au cours des années (Barillé-Boyer et al., 1997, Haure et al. , 2003). Toutefois, les performances de croissance, ainsi que la qualité des huîtres produites sont médiocres et place ce bassin au dernier rang des sites français de production (données du réseau REMORA).

Le Traict du Croisic représente une surface de 650 hectares dont 180 hectares sont dédiés à la conchyliculture. Bien que divers types d’élevage soient pratiqués (huîtres creuses Crassostrea gigas, moules Mytilus edulis, palourdes Venerupis spp.), l’élevage de la coque Cerastoderma edule représente, à lui seul, 140 hectares de concessions soit 76 % de la surface allouée à l’exploitation conchylicole. La production de coques est de 1200 à 2000 tonnes par an, ce qui fait du Traict le premier centre d’élevage et le deuxième producteur français après la baie de Somme où 2500 tonnes par an sont extraites de l’exploitation des gisements naturels (Bonnel, 1986). Il existe peu d’études scientifiques sur l'élevage de la coque dans le Traict du Croisic. Les...

A comparative study of the growth performances in cupped oysters Crassostrea gigas, Crassostrea angulata and their hybrids was conducted from March to October 1999 in a controlled farm with phytoplankton (Skeletonema costatum) input. The individuals, of the same age, were from genitors which had been identified through a marker analysis of the mitochondrial genome (Boudry et al, 1998). As a consequence, two pure offspring were obtained through the crossing of Portuguese oyster C. angulata (AA) genitors and the crossing of Japanese oyster C. gigas (GG) genitors. Two other offsprings were produced through the hybrid crossing of C. gigas female genitors with C. angulata (GA) male genitors on one hand, and C. angulata female genitors with C. gigas (AG) male...

Etude comparative des caractéristiques écophysiologiques et des performances de croissance de l'huître creuse Crassostrea gigas diploïde et triploïde en milieu contrôlé ArchiMer
Haure, Joel; Fortin, Adeline; Dupuy, Beatrice; Nourry, Max; Palvadeau, Hubert; Papin, Mathias; Penisson, Christian; Martin, Jean-louis.
Introduction: Marine farming in France is currently very widely dominated by oyster farming. French oyster production totals 148,467 tons, for a turnover of close to 280 million euros, making France the leading European producer. The two main species concerned are the cup oyster, Crassostrea gigas (140,000 tons) and the flat oyster, Ostrea edulis (2,000 tons), the production of which has collapsed since 1970 following successive epizootics of Marteilia refringens and Bonamia ostreae. French oyster farming is thus in a situation of quasi single-crop farming, with more than 90% of tonnage pertaining to the cup oyster (FAO data from 1993). This situation of quasi single-crop farming leads to the pessimistic observation that one hypothetical crisis in the...
