Methods ＂Direct Pressure Method＂ and ＂Digestion Method＂ were used in this study. Encysted metacercariae were used to infect the fishes. Results Encysted metacercariae of Clonorchis sinensis were found in the muscle of freshwater fishes. All of the fishes collected from these areas were infected by C.sinensis.EspeciaUy,the fishes collected from Shunde were heavyily infected.
