AB  - Since its molecular characterisation, Ostreid herpesvirus 1 (OsHV-1) has been 
      regularly detected in Crassostrea gigas in France. Although its pathogenicity was 
      demonstrated on larval stages, its involvement during mortality outbreaks at the 
      juvenile stage was highly suspected but not evidenced. To investigate mortality 
      outbreaks, the French National Network for Surveillance and Monitoring of Mollusc 
      Health (REPAMO) carried out two surveys in juvenile C. gigas. The first survey 
      lasted from 1998 to 2006 and was an epidemiological inquiry occurring when oyster 
      farmers reported mortality outbreaks. The second survey, a longitudinal one, was 
      set up in 1998 to complete the network observations on OsHV-1. Data analysis 
      showed a specific pattern of mortality outbreaks associated with OsHV-1 
      detection. Ostreid herpesvirus 1 detection mainly appeared during the summer, 
      suggesting the influence of the seawater temperature on its occurrence. It mostly 
      presented a patchy distribution in the field in contrast to the nursery. 
      Significant relationship between OsHV-1 detection and spat mortality was found, 
      preferentially in sheltered and closed environments. The longitudinal survey 
      confirmed most of the network observations. Although subsequent works 
      particularly epidemiological surveys would be useful to confirm the causal link 
      between the detection of OsHV-1 and the mortality outbreaks in juvenile C. gigas, 
      the role of OsHV-1 in oyster mortality is progressing.
