用试验调节臭氧系统比率进行抑制鱼病ceratomyxa shasta感染试验,找到了臭氧作用的最小有效剂量CT值(臭氧残余浓度C与作用时间T的乘积)为1.23。在夏季,用臭氧化水与直接用河水饲养硬头鳟的死亡率分别为1.4%和81.2%。饲养结束时,试验组鱼体明显大于对照组。介绍了适合于水产育苗场的一个完备的生产系统。在华盛顿Cowlitz育苗场,由于沙门氐菌(salmo gairdneri和salmo clarki)及原生动物(ceratomyxa shasta)的侵害,从1980～1985年硬头鳟死亡率在38.8～90.7%之间,平均为62.
To test the ceratomyxa shasta infection test against fish diseases by experimentally adjusting the ozone system ratio, the minimum effective dose CT value (the product of the residual ozone concentration C and the action time T) of ozone was found to be 1.23. Mortality of hard-headed trout with ozonated water and direct river water was 1.4% and 81.2% respectively in summer. At the end of feeding, the fish in the test group was significantly larger than the control group. Introduced a complete production system suitable for aquaculture hatcheries. At the Cowlitz Nursery in Washington, the mortality rate of hard-headed trout from 1980 to 1985 was between 38.8 and 90.7% with an average of 62 due to the attack of salmo gairdneri and salmo clarki and ceratomyxa shasta.
