摘　　要：用３种饵料、４个组合培养褶皱臂尾轮虫，研究饵料对轮虫种群生长、繁殖的影响。结果表明：用光合细菌和鲜酵母混合为饵组，轮虫的最高培养密度达到了１８２０ｍＬ－１，高于其它３组；轮虫的日平均增殖率为０．４３５１，比光合细菌组和鲜酵母组分别增加了６．４％和２５．０％。对轮虫生长、繁殖有明显的促进作用。The Brachionus plicatilis were cultured with 4 kinds of combinations composed of 3 different feeds. With the mixed feed containing PSB and fresh yeast,the density of rotifer reached 1 820 mL -1 ,which was the highest among the 4,and the average daily growth rate of the rotifer was 0.435 1,increased by 6.4%and 25.0% more than those of the groups fed separately with PSB and fresh yeast.Furthermore,this kind of mixed feed can enhance the growth and reproduction of ratifer significantly.
