| The total marine molluscs produced by aquaculture had increased from 1984 to 1990 by 1 000 000 tons going from 1 993 985 tons to 2 964 688 tons. The oyster production remained constant with 870 000 tons. Crassostrea gigas, the Japanese oyster, represented more than 80 % of the oyster production but high mortalities appeared in different countries connected to end of winter and summer mortalities and development of new diseases. The cultivation of Crassostrea virginica, the American oyster, was limited (80 000 tons) by the spreading of two diseases (MSX and dermo) destruction of habitat and over-exploitation. Production of the fiat oyster Ostrea eduIis was still very limited by the presence of the Bonamia diseases in a11 the countries except on... |

| Progeny of Crassostrea virginica oysters, introduced into France in 1992, were reared during 1992 and 1993, to test their growth performances. These assays were performed to investigate the possible replacement of Crassostrea gigas with a non indigenous species, Crassostrea virginica. During the summer of 1993, sporadic mass mortalities (80-90%) occurred among young, Crassastrea virginica, oysters reared in the IFREMER nursery in La Tremblade (Charente Maritime). |

| The eastern oyster once provided major societal and ecosystem benefits, but these benefits have been threatened in recent decades by large declines in oyster harvests. In many areas, recovery of oyster aquaculture faces significant societal opposition and spatial constraints limiting its ability to meet expectations regarding future food needs and provision of ecosystem services. In Virginia, oyster aquaculture has begun to expand, concurrent with an increase in subaqueous leased areas (over 130,000 acres of grounds are currently leased). Though private leases must in theory be used for oyster production, in practice, they can be held for other reasons, such as speculation or intentional exclusion of others. These factors have led to large variation over... |
