引进印尼种大珠母贝繁育F1母贝植核育珠研究

Pearl Production from the Pearl Oyster Pinctada Maxima Progeny Stocks Produced by the Breeders Introduced from Indonesia

以印度尼西亚引进大珠母贝亲本繁育的子代F1群体进行植核育珠,育珠贝数量8086只,在海区休养20 d后,统计育珠母贝的成活率与留核率,比较3月与4月植核手术育珠贝的育珠性状差异。结果表明:休养期结束后,育珠贝的成活率与留核率分别为97.57%和90.69%;育珠期3个月时(6月17日)育珠贝的成活率为81.22%;4月植核育珠母贝的留核率与成活率明显高于在3月的植核育珠母贝,但两者之间差异不具统计学意义(P>0.05)。

In March and April of 2013, nucleus-inserting operation was conducted with the donor and host oysters sampled from the progeny stocks produced by the introduced breeders from Indonesia. The total number of host oyster was 8086. Retention rate and survival rate were estimated after the host oysters were recuperated for 20 days in the sea. Survival rates were calculated at culturing times. Differences in retention rate and survival rate of the host oysters treated in March and April were also evaluated. The results showed that mean values of retention rate and survival rate were 97.57% and 90.69%, respectively, after host oysters were recuperated for 20 days in the sea. Mean survival rate of the host oysters was 81.22%, when they were cultured for approximately 3months. The host oysters treated in April showed higher retention rate and survival rate than those treated in March. However, the differences were not significant between the two groups （P 〉 0.05）. The present results are helpful for pearl production by pearl oyster Pinctada maxima.
