摘　　要：为防治斑鳜聚缩虫、水霉菌并发病,采用多种商品渔药及食盐进行了对比试验,筛选出对聚缩虫和水霉菌有一定杀灭效果且对斑鳜毒性较低的植物源性杀虫剂纤虫净和食盐,并进行了联合药物对该病的治疗试验和药物协同作用评判。试验结果显示,在水温18℃~22℃条件下,0.3 mg·L^(-1)的纤虫净与8 000 mg·L^(-1)食盐联合用药连续浸泡144 h对聚缩虫、水霉菌的死亡率均达到100%,植物源性杀虫剂纤虫净与食盐对聚缩虫药效的相互作用为相加,对水霉菌具有协同增强作用,该药物组合对斑鳜聚缩虫病并发感染水霉菌具有较好的疗效。In order to control the concurrent infection of Zoothamnium spp.and Saprolegnia spp.in Siniperca scherzeri,a comparative experiment was conducted by using various commercial fishery medicine and salt.The study screened the plant-based insecticide Xianchongjin and salt which have certain killing effects on Zoothamnium spp.and Saprolegnia spp.but have lower toxicity to Siniperca scherzeri,and the combined drug treatment experiments and drug synergistic effects evaluation were conducted.The experiment showed that the combined use of 0.3 mg·L^(-1) of Xianchongjin and 8000 mg·L^(-1)salt for continuous soaking for 144 hours resulted in a 100%mortality rate against Zoothamnium spp.and Saprolegnia spp.under the condition of water temperature ranging from 18℃to 22℃.The pharmaceutical coactions between the plant-based insecticide Xianchongjin and salt were additive and synergistically enhanced on Zoothamnium spp.and Saprolegnia spp.,respectively.Overall,this drug combination has a good therapeutic effect on the concurrent infection of Zoothamnium spp.and Saprolegnia spp.
