中文摘要：2004年6-9月,分别采用不同养殖方法、光照度和水层对珠母贝人工苗进行中间培育。试验结果表明：不同养殖方法的成活率和壳高存在显著的差异（P〈0.05）,拱形笼吊养法、柱形笼吊养法、网箱法、开放式吊养法成活率分别为9.4%、27.3%、24.5%、0,壳高分别为26.5、31.4、29.8 mm、-,拄形笼吊养法和网箱法生长快且成活率较高;不同光照度对稚贝的壳高和成活率的影响显著（P〈0.05）,自然光组、800-1000 lx、300-500 lx成活率分别为24.7%、29.6%、36.5%,壳高分别为29.8、28.3、33.6 mm;2-3 m、4-5 m、6-7 m、8-9 m水层成活率分别为27.3%、29.1%、33.6%、38.9%,随着水层的加深而提高（P〈0.05）,壳高分别为31.4、30.6、29.5、30.2 mm,差异不显著。

外文摘要：The intermediate culture of Pinctada margaritifera juveniles produced in a hatchery was conducted using different cultural methods, under different light intensities or at different depths of water layers in gulf of Li-an, Hainan from June to September in 2004. Significant differences in final shell height and survival rate of the juveniles were found in different cultural methods （P 〈 0.05 ）. Statistically, 9.4%, 27.3%, 24.5% and 0% of survival rate were observed in arch cage culture, cylinder cage culture, mesh cage culture and floating raft culture, respectively, with final shell height of each 26.5 mm, 31.4 mm, 29.8 mm and indicating, that the juveniles reared in cylinder cage and mesh cage had better growth and high survival rate. There were significant effects of light intensity on growth and survival rate in the juveniles （P 〈 0.05 ）. In the survival rate of the juveniles, 24.7%, 29.6% and 36.5% were found under natural light, 800 - 1000 lx and 300-500 lx, respectively. For final shell height, 29.8 mm, 28.3 mm and 33.6 mm were observed under natural light, 800 - 1000 lx and 300 - 500 lx, respectively. There was a notice that weak light facilitated the growth of the juveniles. The juveniles had 27.3%, 29.1%, 33.6% and 38.9% of survival （P 〈0.01） and a final shell height of 31.4 mm, 30.6 mm, 29.5 mm and 30.2 mm under a depth of 2 - 3 m, 4 - 5 m, 6 -7 m and 8 -9 m, respectively, without significant differences.
