中文摘要：设立3个实验,分别比较了植核时间、植核贝龄、育珠模式对马氏珠母贝育珠效果影响。实验I,设立A1、A2和A3组,植核时间分别设置4月份、7月份和10月份;实验II,设立B1、B2、B3和B4组,植核贝龄分别设置1.0龄、1.5龄、2.0龄和2.5龄;实验III,设立C1、C2和C3组,育珠模式分别设置海区休养与育珠、池塘休养与育珠和池塘休养与海区育珠。按常规技术植核,经1个月的休养期和15个月的育珠结束后,比较各组间休养与育珠的成活率、留核率、成珠率、优良珠率及育珠绩效值的差异。结果表明:植核时间、植核贝龄、育珠模式对植核贝的成活率和育珠绩效值均存在显著的影响(p值<0.05);对育珠贝的留核率、收珠率和优良珠率无显著性影响(p值>0.05);实验I,A1组(4月份植核)育珠绩效值最高,A2组(7月份植核)育珠绩效值最低;实验II,B2(1.5龄)育珠绩效值最高,B4组(2.5龄)育珠绩效值最低;实验III,C3组(池塘休养与海区育珠)的育珠绩效值最高,C2组(池塘休养与育珠)育珠绩效值最低。马氏珠母贝适宜的植核时间为4月份,适宜的植核贝龄为1.5龄,利用池塘休养结合海区育珠能够有效提高育珠效果。

外文摘要：Three experiments （Experiment I, II and III） were designed to investigate the effects of nucleus-inserting operation time, age and culturing protocols on pearl production traits of pearl oyster Pinctada martensii. Experiment I： Al （nucleus-inserting in April）, A2 （nucleus-inserting in July） and A3 （nucleus-inserting in October） groups were established. Experiment II： four groups were established and designated as Bb B2, B3 and B4 groups. The ages of host oyster in the four groups were 1.0, 1.5, 2.0 and 2.5 years old. Experiment III： three groups （C1, C2 and C3） were developed; the protocols for the C1, C2 and C3 groups were recuperating and culturing in the sea, recuperating and culturing in the pond, and recuperating in the pond and culturing in the sea, respectively. The nucleus-inserting operation was conducted by following the common procedure in the pearl culturing. In Experiment I, II and III, the recuperation and culturing time lasted 1 month and 15 months, respectively. At the end of the experiment, differences in survival, retention rate, obtained pearl rate and perfect pearl rate, performance values were analyzed in Experiment I, II and III. Nucleus-inserting operation time, age and culturing protocols had significant effects on survival in the recuperation and culturing time and performance values （P 〈 0.05）, not on retention rate, obtained pearl rate and perfect pearl rate in Experiment I, II and III（P 〉 0.05）. The At, B2 and C3 had the largest pearl performance values and the A2, B4 and C2 had the smallest pearl performance values. The present studies also suggest that sea cucumber and omnivorous species are desirable species for the pearl culturing protocols in the ponds.
