Associations between farming practices and disease mortality of Pacific oyster Crassostrea gigas in a Mediterranean lagoon
International audience We present the first large-scale, high-resolution spatial and temporal pattern of disease mortality caused by Ostreid herpesvirus 1 (OsHV-1) that has affected Pacific oyster Crassostrea gigas in France every year since 2008, in relation to local farm use. Mortality was monitor...
