Two oyster species are cultivated on the French coasts: the Pacific cupped oyster (Crassostrea gigas), which has been introduced from Japan in the 1970's after the disappearance of the Portuguese oyster Crassostrea angulala, and the European flat oyster (Ostrea edulis). During the second half of the 1960's, the latter suffered successively from two diseases caused by protozoan parasites: marteiliosis (also called "maladie des Abers") and bonamiosis. In France, its production dropped from 20,000 tian in the 1960's to 2,000 today. The impact of these two pathogens as well as the exploitation of the remaining stocks show the importance of the conservation of this species, the only natural European species, whose population is more and more fragmented.

In the case of molluscs, the implementation of selection programs with a precise evaluation of the available genetic variability and the estimate of the transmissibility of the characters as well as their correlations, face two main obstacles: the first one, specific, derives from the existence of some reproduction systems that are sometimes complex and still imperfectly mastered as for the flat oyster plate Ostrea edulis; the other, more general, is directly dictated by the importance of the infrastructures needed to keep a large number of differentiated families in controlled farming conditions. Despite these obstacles, a number of programs have been developed over the last twenty years with encouraging results.
