Abstract：This study was conducted to investigate the effects of shell length of (4 .12 ± 0 .019) mm and (2 .02 ± 0 .012) mm ,body weight of (0 .07 ± 0 .008) g and (0 .03 ± 0 .005) g ,and rearing depth of 2 m ,4m and 5 m on the rearing performance of blacklip pear oyster Pinctada margariti f era under conditions of 500 ind per treatment at water temperature of 23 .09—29 .77 ℃ in a 8—10 depth coast during the intermediate 180 day culture period .The results showed that the large size fingerlings had significantly higher growth rate than the small‐sized fingerlings did ,indicating that (4 .12 ± 0 .019) mm fingerling was more suitable for transferring from hatchery to sea‐cages .There was no significant difference in survival in the finger‐lings with same sizes cultured at the depth of 2 m ,4 m and 5 m (P>0 .05) ,but the survival of fingerlings with different sizes was significantly different when cultured at different depth (P<0 .05) .The findings provide valuable information on the artificial breeding of blacklip pearl oyster .
