摘 要：
为研究高锰酸钾、硫酸铜和次氯酸钠对双叉薮枝虫水母的抑制杀灭效果,在水温(28.8±0.7)℃、盐度为(7.4±0.7)的条件下,分别进行了不同浓度高锰酸钾、硫酸铜和次氯酸钠对双叉薮枝虫水母作用3 h和24 h后致死试验。结果显示:当高锰酸钾浓度为2.0 mg/L时,3 h后双叉薮枝虫水母平均成活率为80.0%,24 h后成活率为40.0%,当高锰酸钾浓度为2.9 mg/L时,3 h后平均成活率为43.3%,24 h后平均成活率为0%;当硫酸铜浓度为0.3 mg/L时,3 h后平均成活率约为100%,24 h后平均成活率为56.7%,当硫酸铜浓度为0.6 mg/L时,3 h后平均成活率约为63.3%,24 h后平均成活率为0%;260 mg/L次氯酸钠浓度作用3 h后,双叉薮枝虫水母成活率仍然有93.3%,但当104 mg/L次氯酸钠浓度作用24 h后,成活率迅速降为36.7%。综合比较,硫酸铜终浓度为0.6 mg/L且作用24 h抑制杀灭水母效果最佳,生产上药物作用24 h后结合池底吸污操作,抑制去除育苗水体中水母效果好。本研究对培育鱼苗过程中如何抑制去除双叉薮枝虫水母具有一定指导意义。

摘 要：
Obelia genicutata Linnaeus grow and breed well with the right temperature,salinity,bait and other conditions.On the one hand,they directly poison and kill the tender seedlings,and on the other hand,jellyfish compete for baits with seedlings.At present,researches on jellyfish at home and abroad mainly focused on the classification of marine jellyfish and freshwater jellyfish,the embryonic development,effects of ecological factors on their growth and the outbreak mechanism.How to control the outbreak of jellyfish in seedling water has not been reported.In order to explore the inhibitory effect of potassium permanganate,copper sulfate and available chlorine on O.genicutata Linnaeus,the lethal effect of potassium permanganate,copper sulfate and available chlorine to O.genicutata Linnaeus were detected respectively at(28.8±0.7)℃ and with a salinity of(7.4±0.7).The results showed that when the concentration of potassium permanganate was 2.0 mg/L,the average survival rate of O.genicutata Linnaeus at 3 hours was 80.0%,while the average survival rate of O.genicutata Linnaeus at 24 hours was 40.0%.When the concentration of potassium permanganate was 2.9 mg/L,the average survival rate of O.genicutata Linnaeus at 3 hours was 43.3%,while the average survival rate of O.genicutata Linnaeus at 24 hours was 0%.When the concentration of copper sulfate was 0.3 mg/L,the average survival rate of O.genicutata Linnaeus at 3 hours was 100%,while the average survival rate of O.genicutata Linnaeus at 24 hours was 56.7%.When the concentration of copper sulfate was 0.6 mg/L,the average survival rate of O.genicutata Linnaeus at 3 hours was 63.3%,while the average survival rate of O.genicutata Linnaeus at 24 hours was 0%.When the concentration of sodium hypochlorit was 260 mg/L,the average survival rate of O.genicutata Linnaeus at 3 hours was still 93.3%.When the concentration of sodium hypochlorit was 104 mg/L,the average survival rate of O.genicutata Linnaeus at 24 hours was rapidly decreased to 36.7%.In conclusion,when the concentration of copper sulfate was 0.6 mg/L,O.genicutata Linnaeus were restrained after 24 hours.The effect will be more pronounced,if combined lowdown.The test results were obtained under the condition of good water quality and low organic content.In practical production,various drugs will be degraded by organic components in water especially in seeding water,which contained a lot of organic matter.Therefore,small water test is needed in the process of use.
