The present study was performed to analyze the infection status of trematode metacercariae in fishes caught from Chunamchosuchi (pond) located in Uichang-gun. Kyongsangnam-do. A total of 130 freshwater fish of 5 species was collected by a fish net and fish traps from November, 1995 to May, 1996. They were examined under a stereomicroscope after artificial digestion with pepsin-HCI solution. A total of 8 species or metacercaria, i. e. Clonorchis sinensis, Echinochnsnw japonicas, Cvathocotwle orientalis, Diplostomun sp.. Metorchis orientalis. Holostephcnw nipponicw, Exorchis oviformis and unidentified echinostome, was detected from them. The metacercariae of C. sinenesis were found in 8/20 (40.0%) Accnthorhodeus Qsmwsi, 20/20 (100%) Cutter breuiccudc, 31/45 (68.9) Cultriculus eigenmanni and 21/25 (84.0%) Pseunorasborc pronga, and the average number of metacercariae detected in each fish species were 1.9, 31.7. I5.3, and 73.0. From the above results, it was confirmed that fresh-water fishes from Chunamchosuchi (pond) were highly infected with metacercariae of avian trematode, i.e. C. orientolis, H. nipponicus. M. oui,entnlis, E. jcponicw and Diplostonum sp., and 4 species of fish. P. parvc, C. breuiccudn, C. eigenmnnni and A. asmussi, were infected with metacaecariae of C. sinensis.
