摘　　要：葡萄牙牡蛎工厂化人工育苗技术包括亲贝促熟、饵料培养、幼虫和稚贝培育等过程。葡萄牙牡蛎受精卵卵径约60μm,在水温25．3℃、盐度26．5及pH8．2条件下受精卵经过16 h左右发育为D形幼虫；幼虫经14～21 d培育进入变态附着期,幼虫培育过程投喂饵料为金藻、小球藻、角毛藻和骨条藻,稚贝加投扁藻；采用聚丙烯塑料片作为幼虫变态附着的附苗器。同时筛选出葡萄牙牡蛎受精卵孵化及幼虫生长的适宜环境条件,并进行了不同饵料投喂效果及不同附苗器的附苗效果试验。This paper reported the industrial artificial breeding technology of Crassostrea angulata, which in-cluding parent shellfish ripening, bait cultivation, and 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 pH 8. 2 conditions, fertilized egg would developed into a D -shaped larvae after 16 hours; and larvae would developed into metamorphosis period after 14～21 days. In the process of larvae cul-tivation, using 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 analyzed the effect of using polypropylene plastic as seedling attaching device. The paper selected the suitable environmen-tal condition of fertilized egg hatching and larval growth of Crassostrea angulata and studied the seedling effect test with different bait feeding and different seedling attaching device.
