Since spat mortality events that were firstly detected in 2008, Mediterranean shellfish industry seeks to exploit the Pacific oyster spat from lagoon natural recruitment. The CRCM, Cepralmar and Ifremer developed accordingly a research project named PRONAMED Phase 1 and 2 - 2010-2014, in order to define the economic potential of spatfall and improve knowledge of the reproductive cycle of Crassostrea gigas in this specific environmental context. The results of the past three year‘s study (2012, 2013, 2014) showed that broodstock have the ability to provide larvae after sexual maturation and spawning. A coincidence was noted between moon phase (new and full moon) and spawnings with an amplifying effect of storms on the intensity of spawning (Ubertini et al....

Infectious diseases are mostly explored using reductionist approaches despite repeated evidence showing them to be strongly in fluenced by numerous interacting host and environmental factors. Many diseases with a complex aetiology therefore remain misunderstood. By developing a holistic approach to tackle the complexity of interactions, we decipher the complex intra-host interactions underlying Pacific oyster mortality syndrome affecting juveniles of Crassostrea gigas, the main oyster species exploited worldwide. Using experimental infections reproducing the natural route of infection and combining thorough molecular analyses of oyster families with contrasted susceptibilities, we demonstrate that the disease is caused by multiple infection with an initial...

Larval recruitement of Crassostrea gigas in a french Mediterranean lagoon ArchiMer

We bring new items in connection with the origins of the natural recruitment variability of the Pacific oyster Crassostrea gigas in Thau lagoon. A poor relationship between " number of larvae" and "number of spat" in 2012 shows a biological lock around oysterculture areas during the metamorphosis in spite of better success of recruitment outside shellfish farming zone. A comprehensive analysis of environmental factors effects and the development of prognosis tools are planned to assist oysterfarmers in rationalization of natural oyster recruitment around Mediterranean lagoon.

Recherche de gisements de captage naturel de Crassostrea gigas en lagune de Thau.Répartition spatiotemporelle du naissain, aspects culturaux et économiques. ArchiMer

Le travail est axé sur la volonté de la filière conchylicole méditerranéenne pour s'approvisionner en naissains d'huîtres creuses sauvages d’origine lagunaire. L'observatoire du captage naturel, mis en place entre 2012 et 2014, a permis de découvrir des gisements de naissains collectés naturellement dans la lagune de Thau selon un protocole défini à l’échelle expérimentale. Bien que très hétérogènes spatialement et temporellement, les densités de naissains sur les collecteurs révèlent des catégories de captage allant de "moyen i. e. 20 à 200 naissains par coupelle" à "excellent i. e. 200 à 2000 naissains par coupelle " sur certaines stations expérimentales. Les expériences de captage naturel à échelle semi-industrielle (avec filière de coupelles en lagune)...
