Abstract: 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.
