| The flat oyster Ostrea edulis was originally reared in several regions of the European waters. The tidal saline ponds on the Atlantic coasts of France were highly productive before being hit by two consecutive epizooties. Parasitic diseases were described on this species, both of them leading 10 economic losses, as heavy mortalities have usually been recorded before the oysters reach the commercial size. Repeated experiments showed that the two diseases, Marteilia refringens and Bonamia ostreae are still active in this environment. Recently, some evidences were given that haemocytoblasts of Crassostrea gigas had the ability to lyze the Bonamia cells. Therefore, in an experiment of contiguous culture of the two species of oysters, the growth, mortality and... |

| This fourth part of the polyploidisation program reports the experiments that were conducted in 1992 and that were devoted to : - the acquiring of a new method using an epifluroescent microscope - the development o a new technique for inducing polyploidy - the triploidy induction for the Europena clam Ruditapes decussatus - the settlement of performance controls conducted on diploid and triploid populations of Ostrea edulis - results of performance controls conducted on diploid and triploid populations of Crassostrea gigas and Ruditapes philippinarum |

| This fifth part of the polyploidisation program reports the experiments that were conducted in 1993 and that were devoted to : - monitoring growth performance of Ostrea edulis diploids and triploids in La Trinité sur Mer and Palavas - monitoring growth performance of Crassostrea gigas diploids and triploids in Port en Bessin, Marennes Oleron (2 locations), Arcachon and Palavas - comparative study of gametogenesis for C. gigas diploids and triploids - comparative study of C. gigas diploids and triploids using sensorial analysis At the end of fifth year, it was clear that triploids are advantageous although such a statement must be moderated according to locations. The gametogenesis stydy showed that triploidy is associated with partial to complete... |
