Resumo: | The cupped oyster, Crassostrea gigas was first introduced in France in 1967 [13]. On the Atlantic coast, the Marennes Oléron Bay (Figure 1) is the first European oyster culture basin with a cupped oyster (Crassostrea gigas) stock of 110,000 tons and an annual output of 30,000 to 40,000 tons. The Ronce oyster bank, located at the south of the bay (Figure 1), is made of 1,600 concessions spread out over 175 ha. It produces 8,000 to 10,000 tons of cupped oysters each year. In Japan, Crassostrea gigas has been cultivated for more than 1,000 years (Farley, 1992). Since the beginning of the 1960's, oyster mortality has multiplied throughout the world (Imaï et al., 1965; Sinderman, 1976; Mackin, 1961; Beattie et al, 1980). In the 60's and 70's, Japan and the west coast of the United-States were struck by summer mortality episodes destroying up to 60% of the C. gigas stocks (Glude, 1975). These mortalities are considered as the most important biological phenomenon of the first half of the 20th century (Gross et Smyth, 1946). If some mortalities are clearly identified as having a pathogenic origin (Beattie et al, 1980; Farley, 1992), others can be happen during exceptional climatic episodes (Mackin, 1961). Numerous mortality cases are often classified as of "unknown origin".
