| 摘 要： | 本实验检测了不同浓度臭氧残留对中国对虾(Penaeus chinensis)、牙鲆（Paralichthys oilvaceus）存活率的影响。结果表明，对虾的耐受力要比牙鲆鱼强，中国对虾在臭氧浓度≥1.0mg/L时，可存活至少48h，而芽鲆在此浓度下3h后，即出现鳃部充血肿胀、呼吸频率加快等不适应现象，48h LC50为0.13mg/L。如果能正确控制臭氧的残留量，利用臭氧净化养殖用水是一个不容质疑的水质净化的好方法。

| Abstract: | Ozone has been widely used in aquaculture applications as a water purification and sterilization method due to its rapid reaction rate intensively capable of killing microbes and few harmful reaction products. But the residual ozone would be harmful to fish and shrimp. Penaeus chinensis and Paralichthys olivaceus were tested separately in this experiment for their survival rate in various ranges of residual ozone levels. Results showed that the tolerance of shrimp for residual ozone levels was much higher than that of the fish, the shrimp would live 48 h in ozone water ≥ 1 mg/L, while fish could not live more than 3 h. Concentration lethal to 50％ of sample fish of Bastard halibut for 48 h was 0.13 mg/L. Compared with other disinfecting method, if we proper control the ozone′ s concontration, ozonation should be an indispensable good treatment method for intensive aquaculture. |
