中文摘要：

为探讨马氏珠母贝与大型海藻的最佳混养体系,分别设置马氏珠母贝稚贝与针叶蕨藻、麒麟菜、长茎葡萄球藻混养实验组及马氏珠母贝稚贝对照组,记录养殖过程中养殖水体NH4^＋-N,NO3^--N的浓度变化及马氏珠母贝稚贝的存活率。结果表明,实验组在养殖过程中可保证较好的水质状况,稚贝存活率也高于对照组;长茎葡萄球藻混养实验组对养殖水体的NH4^＋-N,NO3^--N处理效果最优,分别在第47天和第49天达最低值[（0.015±0.003）mg·L^-1和（0.266±0.002 mg·L^-1],该组的稚贝存活率和藻体日增体质量（0.86 g·d^-1）均最高（93.33%）;不同混养实验组的马氏珠母贝平均壳高日增长量均显著高于对照组。

英文摘要：

In order to explore the optimal co-culture pattern of Pinctada fucata martensii and macroalgae,three coculture patterns,including P. martensii and Caulerpa sertularioides,Caulerpa lentillifera and Eucheuma muricatum（ experimental groups）,and non-co-culture pattern（ control group） were compared. The changes of NH4^＋-N and NO3^--N concentration and survival rate of the juveniles of P. fucata martensii were recorded. The results showed that the co-culture groups purified mariculture water more effectively with higher survival rate of oysters. The Caulerpa lentillifera group absorbed NH4^＋-N and NO3^--N most effectively,which were 0. 015 ± 0. 003 mg·L^-1and 0. 266 ± 0. 002 mg·L^-1respectively,the lowest in the mariculture water,at 47 d and 49 d after the experiment,and had the highest survival rate of P. fucata martensii（ 93. 33%） and the highest daily weight increase（ 0. 86 g·d^-1） of C. lentillifera. The oysters of the experimental groups had significantly higher daily increment of mean shell height than the control group（ P 0. 05）.
