摘　　要：利用室内受控生态系统实验,研究鲢鱼和芦台鲌鱼对富营养化水体中藻类的控制作用。对各受控系统中藻类与浮游动物的统计数据及理化指标,进行了相关性分析和非参数检验的统计分析。实验结果显示,在一定密度下放养滤食性鲢鱼是可以起到控藻作用的。一定密度的芦台鲌鱼与水生植物联合养殖也会起到控藻作用。放养鱼类控藻都要在适当的密度下,密度过大或过小都会影响控藻效果。研究还发现,鱼类的放养会使水体中蓝藻在浮游植物中的比例增大。The effects of silver carp and Lutai-topmouth culter on algae control in eutrophic water were studied through indoor experiments. The correlation analysis and nonparametric tests of physicochemical indexes and biological indexes in the controlled systems were made. The result of the experiments showed that culturing silver carp at proper density can control algae growth effectively,. Culturing freshwater Chinese herring and aquatic plants at appropriate density could also control algae. The fish should be at proper density if used to control algae. While the density offish is too high or too low would both depress the effects. The proportion of cyanobacteria in phytoplankton was increased when fish were put into the water body.
