and 1993 among batches of hatchery-reared larval Pacifie oyster, Crassastrea gigas, and at the beginning of July and in August of 1993 among five batches of 3-7 month old young spats, C. gigas. Observations with transmission electron microscope showed the presence of herpes-like virus particles in infected larvae and young spats. The viruses observed in diseased larvae and affected young spat oysters were very similar. Elevated temperature and crowding may increase susceptibility of oysters to these herpes-like virus infections.
