| 摘 要： | 在褐菖鲉（Sebastiscusmarmoratus）室内养殖条件下，以不换水作为对照组，设置2个石莼（Ulva lactuca）养殖密度梯度，研究了石莼对褐菖鲉养殖水体的生态作用。试验结果表明，石莼对褐菖鲉养殖水体中氮、磷营养盐的清除效果明显。在褐菖鲉养殖水体中分别加入石莼534和801g·m13共9d不换水，与对照组相比，养殖密度为534g·m-3的石莼组对硝态氮（NO3-N）、氨态氮（NH4-N）和无机磷（PO4-P）的清除率分别为83．7％、90．7％和86．5％；养殖密度为801g·m^-3的石莼组对NO3-N、NH4-N和PO4-P的清除率分别为90．1％、96．9％和92．7％。

| Abstract: | Under indoor aquaculture conditions of Sebastiscus marmoratus, the paper studied the ecological effects of Ulva lactuca by comparing two U. lactuca groups at different stocking densities with the control group （ without water exchange）. The results showed that U. lactuca was effective in removing N and P nutrient salts in aquaculture water. The densities of U. lactuca put into S. marmoratus were 534 g·m-3 and 801 g·m-3, respectively. The experiment lasted for 9 days without water exchange. Compared with the control group, the removal efficiencies of NO3-N, NH4-N and PO4-P were 83.7% , 90.7% and 86. 5% , respectively in 534 g·m-3 group, while those of NO3-N, NH4-N and PO4-P were 90. 1% , 96. 9% and 92. 7% , respectively in 801 g·m-3 group. |
