Clonorchis sinensis metacercaria were detected by pepsin digestion. Results A total of 328 tuna were examined. The average infection rate of Clonorchis sinensis was 48.78%, and the average positive rate of positive fish was 4.66. A total of 331 cichlids were examined. The average infection rate of Clonorchis sinensis was 37.46%, and the average positive rate of positive fish was 2.94.
