( Experimental culture of Crassostrea gigas ( Thunberg, 1795, in the estuarine lagoon region of Cananéia ( 25º.05 S; 48º.01 W ) São Paulo, Brazil )

Abstract

An experimental culture with approximately 17,446 spats of Crassostrea gigas (Thunberg, 1795), imported from Sendai, Japan, was carried out in the estuarine lagoon of Cananéia (25°05'S; 48°0l'W) in two Stations. After 4 months the following results were obtained:

Station I - Average shell length                        - 3,4 cm
- Average shell height                                         - 6,4 cm
- Average shell weight                                        - 15,33 g
- Average meat weight                                        - 4,6 g
- Survival rate                                                        - 66%
- C/A (length/height)                                            - 0,53

Station II - Shell length                        -3,6 and
                                                                 -3,7 cm
- Average shell height                          -6,4 cm
- Average shell weight                         -13,54 g
- Average meat weight                       - 4,1 g
- Survival rate                                       - 68,30%
- C/A (length/height)                          - 0,56 and
                                                                - 0,59

From the collected data it may be concluded that the estuarine-lagoon of Cananéia offers suitable conditions for a culture of Crassostrea gigas.
