Abstract: This paper reports the factory artificial breeding technology of Crassostrea angulata, which including parent shellfish ripening, bait cultivation, larvae and juvenile cultivation. Results were listed as follows: fertilized egg diameter of Crassostrea angulata was about 60 μm; under the temperature of 25.3℃, salinity of 26.5 and pH8.2 conditions, fertilized egg would developed into a D-shaped larvae after 16 hours; and larvae would developed into metamorphosis periond after 14~21 days. In the process of larvae cultivation, we used Isochrysis galbana, Chlorella vulgaris, Chaeroeeros moelleri and Skeletonema costatum as bait feeding, and fed Platymonas subcordiformis in the process of juvenile cultivation. The study also analysed the effect of using polypropylene plastic as seedling attaching device. selected the suitable environmental condition of Crassostrea angulata fertilized egg hatching and larval growth. Meanwhile, we studied the seedling effect test with different bait feeding and different seedling attaching device.
