本研究采用荧光显微技术对香港巨牡蛎(Crassostrea hongkongensis)♀×近江牡蛎(C.ariakensis)♂的受精过程以及受精卵的早期发育进行了观察。结果表明:杂交组的受精率为35.3%±1.86%,大部分受精卵可以正常发育,但其发育速度相对种内受精组较慢,实验已获得了成活的2龄个体。本研究证明了香港巨牡蛎♀×近江牡蛎♂种间杂交的可行性。 In this study, fluorescence microscopy was used to study the fertilization process and the early development of fertilized eggs of Crassostrea hongkongensis ♀ × C. oyster. The results showed that the fertilization rate of the hybrid group was 35.3% ± 1.86%, most of the fertilized eggs could develop normally, but the development rate of the hybrid fertilized group was slower than that of the intraspecific fertilization group. The 2-year-old individuals were obtained. This study demonstrates the feasibility of crossing Hong Kong giant oyster ♀ × oyster ♂ interspecific hybrids.
