Seven kinds of larval trematodes and undetermined larvae were found from thirteen species of the fish collected in the river.
Among these larval trematodes, Clonorchis sinensis metacercaria was found from eight species and Metagonimus yokogawai cyst from four species of the fish. Similary, Exorchis oviformis metacercaria was parasitized in eleven, Metacercaria hasegawai in nine, Echinochasmus species in seven and Cyathococyl orientalis in two species of the fish.
The intensity of infestation with the metacercaria of C. sinensis, expressed in the average number of metacercariae per gram of flesh, was relatively low (ᄋ, 75) in Hemibarbus labeo. The average number in the other fish were very low(less than 0.5). In the case of M» yokogawai, the average number of larvae was very low in almost all of fish except H. labeo.
