摘　　要：用面包酵母室内高密度培养褶皱臂尾轮虫，结果发现：1．5g／（10^5·d）的较高投饵量，适合于接种密度约为50个／ml的褶皱臂尾轮虫培养，而投饵量为1．0～1．2g／（10^6·d）时，适合于200个／ml以上较高密度的褶皱臂尾轮虫培养。投饵量为1．5g／（10^6·d）时，不适于500个／ml以上接种密度的褶皱臂尾轮虫培养。若褶皱臂尾轮虫密度继续高至1000个／ml以上，投喂量则需进一步降低至1．0g／（10^6·d）以下。褶皱臂尾轮虫接种密度低至30个／ml以下时，除酵母外，适当添加一定量（1／3以上体积）的单胞藻，可提高褶皱臂尾轮虫的增殖速度，降低褶皱臂尾轮虫培育的风险。Rotifer Brachionus plicatilis was cultivated at high density by baker＇s yeast. The results showed that the yeast was suitably fed at a rate of 1.5 g/（10^6·d） during the rotifer cultivation at a density of about 50 individuals/ml, while the yeast was suitably fed at a rate of 1.0-1.2 g/（10^6·d）for the rotifer cultivation at a density of over 200 individuals/ml. The yeast was unsuitably fed at a rate of over 1.5 g/ （10^6·d） in the rotifer cultivation at a density of over 500 individuals/ml. When the rotifer density was kept increasing（up to over 1000 individuals/ml）, the feeding rate of the yeast was found to decrease （below 1.0 g/（10^6·d）. When the density of the rotifer was low（30 individuals/ml）, some unicellular algae were added to improve the proliferation of the rotifer with less cultivation risk.
