摘　　要：[目的]研究海洋尖尾藻培养液的基本特征。[方法]以亚心形扁藻(Platymonas subcordiformis)和米氏凯伦藻(Karenia mikimotoi)作为海洋尖尾藻(Oxyrrhis marina)的饵料进行室内静置培养。[结果]海洋尖尾藻静置培养过程中培养液颜色发生变化,先由饵料藻培养液的颜色变为淡粉红色至粉红色,最终变为无色。海洋尖尾藻培养过程中瓶底首先出现少量沉淀物,随着培养时间延长,沉淀物上附着的饵料藻开始逐渐增多然后慢慢减少直至消失。[结论]该研究获得了海洋尖尾藻培养液的基本牲征,为海洋尖尾藻生态学研究提供了参考。[ Objective ] To study the basic features of the culture medium of Oxyrrhis marina. [ Method ] The Oxyrrhis marina was indoor cul- tured with the baits of Platymonas subcordiformis and Karenia mikimotoi. [ Result] During the static culture process, the color of the culture medium of Oxyrrhis marina changed firstly from light pink to pink and finally to colorless. Some precipitate appeared at the bottle bottom, with the extending culture time, the bait algae attached to the precipitate gradually increased, then decreased and finally disappeared. [ Conclu- sion ] The study provides references for the screening of the culture medium of Oxyrrhis marina and realizes its long-term culture.
