摘　　要：通过设立固定调查点进行定期调查,并辅以门出诊和不定期巡回调查的方式,于2015至2017年对福建省部分棘胸蛙养殖场发生病害的种类、流行情况及危害程度进行调查与分析。调查结果显示,福建省养殖棘胸蛙的主要病害有17种,其中蝌蚪期的病害有10种,幼成蛙期的病害有7种。蝌蚪期危害最严重的病害是六鞭毛虫病和吸管虫病,两者的年平均发病率分别为22.5%和25.2%,年平均死亡率分别为13.1%和12.4%;幼成蛙期危害最严重的病害是歪头病,其年平均发病率和年平均死亡率分别达到16.5%和8.6%。病害的发生和死亡主要集中于夏秋高温季节,而在冬春季节,病害的发生率和死亡率均较低。通过调查,初步摸清了福建省养殖棘胸蛙病害的发生情况,为养殖生产中的病害防治工作提供了科学依据。Through the establishment of fixed investigation points to carry out regular investigation,supplemented by door-to-door visits and irregular itinerant investigation,from 2015 to 2017,the types,epidemic situation and harm degree of some diseases in the breeding area of Rana spinosa farm in Fujian Province were investigated and analyzed.The results showed that there were 17 kinds of diseases occurring on cultured R.spinosa in Fujian Province,among which 10 were in tadpole-period and 7 were in frog-period.The most serious diseases in tadpole-period were Hexamita disease and Suctorida disease,while the average annual incidence of which was 22.5%and 25.2%,and the annual average mortality rate was 13.1%and 12.4%,respectively.The most serious disease in frog-period was head-crooked disease,and the annual average morbidity and annual average mortality rate were 16.5%and 8.6%,respectively.The occurrence and death of diseases were mainly concentrated in the high temperature season of summer and autumn,while the incidence and mortality of diseases were low in winter and spring.By the investigation,the occurrence of diseases on cultured R.spinosa in Fujian Province were preliminarily found out,which provided scientific basis for the prevention and control of diseases in breeding production.
