| 摘 要： | 作为系统研究的第四部分，就捕食竞争、食物等因素与海洋纤毛虫-巨大拟阿脑虫（纤毛门，盾纤目）种群生长的关系进行了探讨。结果显示，单独或混合培养的纤毛虫对细菌生长均有很强的抑制作用。在竞争者存在时，巨大拟阿脑虫和扇形游仆虫的种群生长均受到了不同程度的制约而维持较为稳定的共存状态。实验表明，盾纤类纤毛虫作为高效的食菌者对于维持一个健康的养殖环境具有积极意义。

| Abstract: | The scuticociliate Paranophrys magna Borror,1972 is commonly found in a variety of marine waters , especially in mariculture biotope. The effects of different initial population density, temperature, salinity and pH on the population growth have been studied using experimental methods in previous reports. As the fourth part of this series, the present paper deals with the effects of the competitor (a hypotrichous ciliate) and food on the population growth of Paranophrys magna\%. The experiment was divided ... |
