In 1989, a selected strain of flat oyster. Ostrea edulis, was produced from breeders that survived Bonamia ostreae and that were over selected by injection of purified parasites. This generation (G 1) was compared to native oysters which had settled during the same year. After a growing period of 21 months, the oysters were tested according to three procedures: exposure to natural infection in an intertidal area, maintenance at the laboratory in tanks near heavily infested oysters, injection of parasites. The test lasted 7 months. In each procedure, oysters of the first generation (G1) showed a better survival rate than control oysters (72 to 94% versus 48 to 66%). On the other hand, the highest mortalities were observed among injected oysters (G1 and... |
