Resumo: | The Stanway cylinder was tested in the bay of Arcachon from September 1989 to August 1991. Trials were mainly performed on the Japanese oyster Crassostrea gigas in a wind-exposed area. The seed, spat, 18 month old oysters development and fattening of 2 year old oysters were studied. Compared to plastic bags the Stanway cylinder has high positive effects on survival and growth of Crassostrea gigas seed. It also has positive effects on commercial sized Crassostrea gigas fattening. Nevertheless, the cylinder has negative effects on the growth of Crassostrea gigas spat and 18 month old oysters, except for width. However, oyster quality is greatly improve : higher condition index, higher carbohydrate contents and higher shell densities were recorded. Because Arcachon oyster industry is affected when selling generally poor meaty oysters with fragile and friable shells during the height of the season, November to January, the use of the cylinder for rearing 18 month old oysters is advantageous. To increase the efficiency of the system, the cylinder could be locked during the growing periods.
