A total of 1479 fish classified into 30 species were collected during
the study period. Among them, 1316 (89%) comprised of 20
different species of the cyprinoid family and 163 (11%) belonging
to 8 families of non-cyprinoids (Table 1). Small liver fluke metacercariae
were recovered from 10 out of 20 cyprinoid families, but
none at all from fish of the non-cyprinoid families (Table 1).
The prevalence and the intensity of infection of 10 cyprinoid
fish species are summarized in Table 2. The prevalence varied from
2.1% to 66.7% depending on fish species, with the mean prevalence
of 17.5% in the total of 929 cyprinoid fishes. Among those,
Cyclocheilichthys apagon, Hampala dispar, Puntius brevis and Systomus
orphoides showed relatively high (>20%) prevalence. Although
Barbodes altus also showed high prevalence (66.7%), this result was
based on the examination of only 3 fish so that itwas not included in
further data analyses. The prevalence of other five cyprinoid species
