In recent years, green tide of Ulva prolifera and red tide of microalgae occurred frequently with increasing marine pollution such as eutrophication in Chinese coastal waters. In this paper, the competitive inhibitory effects of U. prolifera fresh algae, U. prolifera culture filtrate and U. prolifera dry powder in different contents on Prorocentrum donghaiense were studied under laboratory simulation conditions. U. prolifera fresh algae, U. prolifera culture filtrate and U. prolifera dry powder all had inhibitory effects on P. donghaiense under the condition that the initial mass content was greater than 1 g/L, and the inhibitory intensity of U. prolifera dry powder was much higher than U. prolifera culture filtrate and U. prolifera fresh algae. In the co-culture groups, the phenomenon of “low promotion and high inhibition” appeared. Low content of U. prolifera promoted the growth of P. donghaiense, and high content of U. prolifera inhibited the growth of P. donghaiense. In addition, the inhibitory effects increased with the increasing content of U. prolifera. This inhibitory effects of U. prolifera on P. donghaiense may come from the competition and consumption of nutrients. In addition, the effects may also come from the influence of allelopathic substances released by U. prolifera on P. donghaiense. The inhibitory effects of U. prolifera on P. donghaiense can provide ideas and methods for the biological control of red tide.
