Etude pluridiciplinaire de la DYNAmique des MOrtalités estivales dans le bassin de Marennes- Oléron : Dynamique des mortalités en relation avec la reproduction in situ et la température - Suivi de paramètres hémocytaires - Synergie écologie côtière et activité hémocytaire

Massive abnormal mortalities of flat oysters Crassostrea during the summer period are nothing new, and such episodes have been described in scientific literature for about forty years. Numerous studies demonstrate that there is not one single identified cause to this phenomenon and that it is, on the contrary, a combination of different parameters. This program proposes a multidisciplinary approach to the problem of summer mortality of C. gigas in which the working hypothesis is that these mortalities result from the interaction of three parameters: environment, host and pathogens. As a consequence, this program gathers all the necessary competences for the study of these interactions: competences in genetics, physiology, immunology, ecotoxicology, environment as well as regional and professional structures.
