The intertidal zone is characterized by a sharp vertical gradient of environmental stress, which structures species distribution and their interactions. Few studies, however, have examined the influence of tidal height on host–pathogen interactions. Here, we investigated how the tidal height influence outbreak of the Ostreid herpesvirus type 1 (OsHV-1) affecting the Pacific oyster. A volunteer network composed of 20 oyster growers monitored the survival of 28 batches of oysters during an epizootic event in Southern Brittany, France. Oysters were spat from wild collection or hatchery production. The sampling sites were spread over a 150-km2 area with a tidal height ranging from 0.98 to 2.90 m. Concomitantly, we followed survival of oyster spats in relation...

Mazurié, Joseph; Martin, Anne-genevieve; Fleury, Pierre-gildas; Bouget, Jean-francois.
Un programme de soutien à la conchyliculture était inscrit au contrat Etat-région 1994-1998, intitulé "amélioration des écloseries et soutien à la conchyliculture bretonne". Ce rapport synthétise les résultats acquis au laboratoire Ifiemer DRVIRA-LCB de La Trinité-sur- Mer, qui portent sur la surveillance et l'amélioration génétique : 3 volumes plus détaillés traitant du suivi de la croissance, de la surveillance des maladies et d'un système de surveillance biologique de la qualité de l'eau sont joints. La partie relative à la maîtrise des écloseries est rapportée séparément par le laboratoire de physiologie des mollusques d'Ifiemer Brest.
