Fig. 3. The prevalence of Exorchis sp. in S. asotus collected from the marshland of Poyang Lake from 2012 to 2016. (A) The adult S. asotus fish collected from Shi Li Hu were kept in plastic containers supplied with water. (B) The intestine of collected S. asotus fish were dissected in a glass Petri dish containing 0.75% saline solution. (C) The isolated Exorchis sp. adult trematodes isolated from the intestine of infected S. asotus. (D) The infection rate of Exorchis sp. in S. asotus is 56.82%, 75.56%, 67.09%, 63.81% and 72.18% from 2012 to 2016, respectively. (E) The intensity of infection of Exorchis sp. in S. asotus is 14.45, 15.24, 16.87, 14.18 and 12.22 per fish from 2012 to 2016, respectively. (F) The average infection rate of Exorchis sp. in S. asotus collected from the marshland of Poyang Lake from 2012 to 2016 was 65.79%. (G) The average intensity of infection of Exorchis sp. in S. asotus collected from the marshland of Poyang Lake from 2012 to 2016 was 14.21 per fish.
