| 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,... |

| Le ROCCH produit les données chimiques nécessaires à l'évaluation de la qualité chimique des eaux marines, et notamment la qualité des zones conchylicoles françaises. En 2020, un total de 110 échantillons de mollusques collectés et analysés (dont 40 points hors zones conchylicoles suivies) permet de dresser un bilan de la qualité des côtes métropolitaines. Un secteur présente une non – conformité avec le dépassement de la teneur admissible en plomb dans les moules de la baie de Daoulas (sud – est de la rade de Brest). Plusieurs secteurs atteignent ou dépassent 50 % de la concentration-seuil : le nord de la rade de Brest (HAP), le sud de la rade de Brest (plomb et cadmium), le pertuis charentais (cadmium), l’estuaire de la Gironde (cadmium), l’étang de... |

| In the case of molluscs, the implementation of selection programs with a precise evaluation of the available genetic variability and the estimate of the transmissibility of the characters as well as their correlations, face two main obstacles: the first one, specific, derives from the existence of some reproduction systems that are sometimes complex and still imperfectly mastered as for the flat oyster plate Ostrea edulis; the other, more general, is directly dictated by the importance of the infrastructures needed to keep a large number of differentiated families in controlled farming conditions. Despite these obstacles, a number of programs have been developed over the last twenty years with encouraging results. |

| Despite the fact that the involvement of environmental factors in the physiology of the japanese oyster C. gigas is fully described, regulatory peptides are not known. In this study, we focused on peptidergic control of egg-laying. In order to characterize peptides involved in the regulation of egg-laying in C. gigas, the cuttlefish S. officinalis was used as a model. Firstly, regulatory peptides were investigated in the cuttlefish by peptidomic analysis. This approach led to the identification of eleven new ovarian regulatory peptides. Based on conserved tags, these peptides have been classified into two families: the SepCRPs (Sepia Capsule Releasing Peptides) and the OJPs (Ovarian Jelly Peptides). Released by oocytes into the genital coelom, they are... |

| Deuxième volet du programme d'essai d'acclimatation de l'huître américaine Crassostrea virginica, ce rapport présente les actions et les résultats de l'année 1993 qui a été consacrée au suivi des performances comparées de croissance des populations de C. gigas et C. virginica produites en 1992, ceci en trois sites différents: • dans le bassin de Marennes-Oléron en claire et sur estran, à la station IFREMER de Bouin en élevage intensif, au CREAA sur l'Ile d'Oléron en marais extensif. Au terme de cette seconde année d'étude, il est d'ores et déjà possible d'affirmer que que la souche anglaise de C. virginica étudiée ne présente pas de caractéristiques de croissance susceptibles de la rendre compétitive par rapport au témoin Crassostrea gigas et cela d'autant... |

| Shellfish areas usually receive a large number of introduced species. During the present project, we specially focused on 4 marine benthic molluscs introduced in shellfish areas along the Channel and Atlantic coasts of France: the gastropods Crepidula fornicata, Ocinebrellus inornatus and Cyclope neritea, and the bivalve Ruditapes philippinarum. Our study was conducted according to three main axes: (i) the characterization of introduction and expansion patterns of species within their newly colonized area. In the three invasive gastropods C. fornnicata, C. neritea and 0. inornatus, a high level of genetic diversity was detected in the French populations which indicated a complex process of introduction (with multiple population sources or secondary... |

| in mollusc hatcheries. Consequently, we assessed themost commonly used species to establish their growth and size profiles, their cytomorphological, biochemical, biomolecular identification as well as their cytometer signs, and also their ability to grow under extreme conditions of temperature and salinity. This work aimed at matching the conformity of the strains used in Argenton (dispatched to most of the French commercial hatcheries) to those of a referenced culture collection. A previous screening preceded this study, because of the 45 species and/or clones held originally, Argenton kept no more than 15 species. As most of the latter are also represented in referenced collection, our strains are therefore correctly identified. On the other hand, the... |

| La biodéposition liée à l'exploitation des filières de moules est responsable de l' accumulation de particules fines dans l'environnement marin. Cette biodéposition consiste, à travers la formation de feces et de pseudo feces, en un transfert de particules sestoniques, de la tranche d'eau vers le sédiment. Au cours de ce travail nous avons étudié l'influence des cycles de marée et de l'intensité de celle-ci sur la biodéposition, à travers la mesure de flux verticaux de particules. De même, l'impact de cette biodéposition (aspects qualitatifs et quantitatifs) sur le seston a été abordé. Notre étude montre une variation de l'intensité des flux liée au cycle de marée. Les flux les plus importants sont mesurés lorsque les courants sont les plus intenses,... |

| Among the infectious diseases observed in bivalve molluscs, viral infections are often not well known because of a certain inadequacy of the diagnostic techniques usually applied during instances of mortality. In fact, photonic microscopy was still the base method for analysing specimens in several laboratories working on pathologies in molluscs. This technique is insufficient in the event of a pathology of viral etiology if it is not supplemented by other approaches such as the electronic microscope, research of cytopathogenic effects on cell lines or detection of the infectious agent with the help of specific reagents (specific antibodies and nucleic probes). Moreover, since no bivalve mollusc cell line is currently available, in vitro research of... |

| La charge énergétique adénylique (CEA) est le reflet de l'énergie disponible dans les cellules. Ses variations ont été recherchées comme indice physiologique pour détecter un stress chez les crevettes péneides P. vannamei et P. stylirosrtis et chez l' huître perlière Pinctada margaririfera. L'étude a porté dans un premier temps, sur la recherche des conditions optimales de préparation des échantillons aussi bien pour les crevettes que pour la nacre et dans un second temps sur des variations dues aux stress. La plupart des stress induits (hypoxie, vibriose) ne provoquent pas de variations significatives de la charge énergétique des crevettes p>0.05. Chez l'huître perlière une émersion à 20°C, 30°C et 40°C(p <0.05) ou une baisse de salinité ( 10%o)... |

| Innovations in the nursery culture and maturation of bivalves are being worked on at aIl levels of research and production, but transfer to the development stage must be effected differently in each case. Over the past twenty years, there have been a great many innovations in bivalve rearing, most of which may be described in terms of rearing conditions: higher and lower densities; confined or open environemnt; overflow; upwelling; floating, suspended, raised or ground systems, etc. The quality of an innovation is characterized by its influence on the efficient operation of the specific culture program and by how easily it may be transferred. |
