| Created in 1986, the REPAMO network (Network of mollusc pathology), is a national zoosanitary surveillance network of shellfish health status along the French coasts. Its activities are in keeping with two European Directives, 91 /67/EEC and 95/70/EC and are a patt of the institutional tasks ofIfremer. The aims of the network are to prevent the introduction and spread of exotic pathogens and to survey the evolution of notifiable pathogens already present in France. The network focused on the survey of listed diseases (bonamiosis and marteiliosis of flat oyster) in two areas under agreement process (Banc de Granville and zone X). In 2004, no sample couId be analysed to these two areas because of the difficulty to obtain flat oysters (sparse oyster beds,... |

| A study on nitrogenous and phosphorous waste production in European seabass (Dicentrarchus labrax) was carried out in a flow-through land-based farm. The main objectives were (i) to calculate nitrogenous (N) and phosphorous (P) waste production (particulate and dissolved) from in situ measurements for different rearing ponds with specific fish biomasses, fish sizes and flow rates, (ii) to establish nitrogenous and phosphorous waste production budgets, ratios and equations, and (iii) to compare, for the whole farm, in situ measurements to estimate N and P waste production from waste equations. Waste production was manifest by an increase in concentrations of total ammonia nitrogen, total Kjeldhal nitrogen, particulate nitrogen, dissolved phosphorus and... |

| Two kinetics of contamination of Carcinus maenas by 59Fe have been determined in relation with the preponderent physico-chemical state of the metal in the experimental medium. The soluble forms seem to be accumulated essentially in internal tissues by biological process when particulate forms are accumulated in tissues in contact with sea water. The whole contamination and the kinetics of contamination of the whole crab Carcinus maenas is dependant of the contamination and the kinetic of contamination of the external tissues, gills and exoskeleton, in contact with sea water.

| Au cours de cette étude, nous avons étudié l'impact de la biodéposition sur les bassins conchylicoles. La biodéposition constitue un "concentrateur" de particules fines au niveau du sédiment. Cet impact est particulièrement évident sur les sédiments sableux et concerne la granulométrie, les taux de matière organique, la concentration des métaux et des hydrocarbures. Une étude comparée est faite entre estran sableux et bassin de type "claire" à sédiment argileux. L'impact de la biodéposition sur les sédiments sableux n'est pas irréversible. Le bassin fermé avec un sédiment argileux agit comme un concentrateur-rétenteur de particules et des contaminants potentiels. Ceci souligne le rôle "tampon" des marais maritimes entre milieu continental et milieu marin. |

| In the booming context of shrimp culture in French Caledonia, some research actions need to be considered in order (i) to make sure this production will not impact the quality and biodiversity of the coastal environment it is contingent upon (ii) for the field to highlight, based on objective bases, its good "environmental image", for an efficient commercialization of its products. In the framework of the MOM project, a number of actions have been carried out: Action 1: A bibliographical synthesis of the impact of shrimp culture on coastal environment has been conducted, taking into account the works carried out throughout the world and in French Caledonia in order to draw the main issues the Territory will have to deal with. It seems necessary to start... |

| Introduction : Growth and survival are the life-history traits of the most interest for oyster production since they determine biomass output (growth x survival). This study aimed to investigate whether there is genetic basis for growth, survival and their plasticity to know if a selection program is conceivable for these traits. Material and Methods : Nested half-sibs mating design was used to produce families of oysters: 5 males were each mated to three females producing 5 half-sibs families, each containing 3 full-sib families. At 15 months of age (May 1999), each full-sibs family was randomly split into five groups which were given different treatments. Two groups were placed in a constant environment: one with low food resources and another with high... |

| 1. A quantitative and electrophoretic study of copper and zinc in hemolymph of the crustacea decapoda, Carcinus maenas, has been carried out. 2. Most of the copper was linked with hemocyanin.3. All copper-binding proteins are hemocyanin.4. Zinc belongs to three different compartments: more than 68% is linked with hemocyanin; about 10% is shown in the fraction containing blood cells, lipids and carotenoids; 15% is present in the hemolymph under a soluble and dialysable form. 5. Specific zinc-binding protein has not been found out in the serum of Carcinus maenas.6. Zinc linked with hemocyanin is found on high molecular weight protein fractions only. [NOT CONTROLLED OCR] |

| Ifremer, Nantes University and the township community "CAP Atlantique" have joined their skills to try to better understand how two key conchological areas in the shore economy of the Pays de la Loire area develop, especially since, environmentally, little is known about them, and because they face recurrent issues on the zootechnic level. This programme encompasses two main topics: assessment of environmental inputs (catchments areas input, contaminants evolution in the area, and impact on the conchological zones) and a study of the conchological culture (growth, mortality, analysis of the stocks). Concomitantly, operational tools (hydrodynamic and flux transfer models, databases, SIG) are developed to improve local management of the sites and information... |

| 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... |

| Complex interactions between oyster, environment and pathogens were observed during the MOREST (2001-2005) project on summer mortality events of Crassostrea gigas oysters in France. The talk will show how nutrition level increasing reproductive intensity generates a risk for pathogen infection under synergistic effect of temperature and stress. Moreover, a genetic component is associated to specific reproductive performances and spawning behaviour. To better understand origin of such resistance or susceptibility to summer mortality, other characteristics as stress susceptibility, energy management and hemocyte activities of oysters from the two phenotypes were compared. This first comparison suggests interactions between stress, reproduction and defence... |

| 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... |

| Créé en 1992, le réseau REPAMO (REseau de PAthologie des MOllusques) est un réseau de surveillance de la santé des mollusques marins du littoral français. Son activité s'inscrit dans le cadre de deux Directives Européennes, les Directives 91 /67/CEE et 95/70/CE. Les objectifs du réseau sont de prévenir l'introduction et la propagation d'organismes pathogènes, en particulier ceux à déclaration obligatoire et de surveiller l'évolution de ceux déjà présents sur le territoire national. Ces activités font parties des missions institutionnelles de l'IFREMER. La surveillance assurée par le réseau vise en premier lieu les infections à déclaration obligatoire présentes en France, la bonamiose à Bonamia ostreae et la Marteiliose à Marteilia refringens chez l'huître... |

| The rates of manganese in the tissues of Cancer irroratus, exoskeleton, hepatopancreas, hypoderm, gills, hemolymph and muscles, are generally low and show variations during the intermoult cycle. These variations are, for the most part, depending on the water content fluctuations in the tissues. For each tissue or organ, the rates of manganese are higher than those in sea water and hemolymph, showing that each of them is able to concentrate manganese. In Cancer irroratus, manganese seems to he rather an intracellular or çonstitutive element than a flowing metabolite. In the gills, this metal seems to be accumulated essentially by filtration of manganese in a particulate or colloidal form in sea water. In the exoskeleton, a very close correlation occurs... |

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... |

| Le transfert d'huîtres d'un secteur de production à un autre, à différents stades de l'élevage est une pratique courante chez les professionnels. L'influence de ces transferts sur la croissance et la survie est actuellement inconnue. Ainsi, il est apparu opportun d'essayer de mettre en évidence le degré de tolérance de diverses populations d'huîtres creuses vis à vis de transferts multiples dans des écosystèmes à productivité différentes. Cette étude a pris en compte la variabilité de deux paramètres (mortalité et croissance) de différentes familles d'huîtres creuses C. gigas soumises à des transferts plus ou moins fréquents entre deux milieux d'élevage dissemblables par la quantité de nourriture apportée (Skeletonema costatum). L'un des deux bassins... |

| 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. Plusieurs études ont été réalisées en 2002 : - Creocean et le Crema ont estimé la biomasse de crépidules dans la partie subtidal de la baie à environ... |

| 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. |
