영문 초록

In order to survey the infection status of freshwater fishes with trematode metacercariae in Asan Lake located in Kyunggi-do and Chungchongnam-do, a total of 118 freshwater fishes of 9 species were captured with a fish net from late April to early June 1998. The fishes captured were brought to our laboratory and examined under a strereomicroscope after the artificial digestion. Eight out of nine species examined were found to be infected with metacercariae Clonorchis sinensis metacercariae(MC) were detected from 5 species of the fishes, Exorchis ovijormis MC from 8 species, Metrochis orientalis MC from 4 species and Echinochasmus japonicus MC from one species. In the infection rates of Clonorchis sinensis, Gnathopogon atromoculatus was the highest(53.3%), followed by Pseudorasbora parva(45.5%), Aphyocypris chinensis(40.0%), Carassius auratus(11.1%) and Hemiculter eigenmani (4.8%). The infection rate with the E. ovφrmis MC as varied from 18.1 % to 54.5% in 8 species of freshwater fishes. The infection rate as with the Metrochis orientalis as relatively low and variable from 2.4% to 36.4% in 4 species of freshwater fishes. The result of survey indicates that the freshwater fishes could be sources of human infection of C. sinensis and E. japonicus in the surveyed area.
