Control experiments on the concurrent infection of Saprolegnia spp.by the Zoothamnuim spp.disease of Siniperca scherzeri
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 8 000 mg·L-1salt 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.
