| In marine molluscan aqauculture, infectious agents are regularly cited in literature associated with mass mortalities as emergin diseases, but the causal link is often based on very few argumeents. 24 ways to demonstrate causal links from epidemiolgical, ecological and marine pathology literature feasible for marine molluscs are given. Those criteria were applied to the ewample of Bonamia ostreae for Ostrea edulis and Herpesvirus for spats and larvae of Crassostrea gigas. Three principles could be applied in marine field for choosing criteria wich should be taken in priority : the demonstration must be given at three levels of organization, organ individual, population, the demonstration must keeps maximum epidemiological criterias, and then mixes... |

| The European flat oyster Ostrea edulis has been considered as the traditional French oyster for a very long time and has now nearly disappeared from our farms, as a consequence of the two successive epizootic of the Marteilia refringens parasite and Bonamia ostreae. The actual quasi monoculture of Crassostrea gigas has made necessary the search for a diversification in oyster culture, including the search for a new start of the indigenous flat oyster culture. The Ifremer has been conducting parallel works since 1985 in order to better understand the biology of the parasite as well as to try and select different lines of flat oyster resistant to Bonamia ostreae. |
