During February 1982 to Septemner 1983, a total of 105 domestic ducks (Anas platyrhynchos var. domestica Linnaeus) were collected from Ichon Gun, Puasn City, Chunchon City, Yanggu Gun, Taejeon City and unknown areas in Korea. In the results, six trematode and one nematode species of helminth parasites were obtained and described as follows: Amphimerus anatis Yamaguti, 1933, Echinostoma miyagawai Ishii, 1932, Echinochasmus japonicus Tanabe, 1926, Cryptocotyle sp., Notocotylus attenuatus (Rudolphi, 1809) Kossack, 1911, Apatemon sp, and nematode species, Heterakis gallinarum Schrank, 1788. From this collection, Amphimerus anatis Yamaguti, 1933, Echinochasmus japonicus Tanabe, 1926, Genus Cryptocotyle Luhe, 1899 and genus Apatemon Szidat, 1928 were firtstly recorded in Korea.

The prevalence of C. sinensis infection along the Nam river, Korea, was 38.7% of 5,291 people examined. Prevalence rates varied from 42% at the upper stream to 34% at the middle stream and 40% at the down stream region. Rates were highest (53.4-54.3%) in the 30-59 years of age group. The positive rates in primary school chidren, school students, teachers and local officers, and other inhabitants were 16.5%, 22.6%, 46.2% and 49.6% respectively. 53.6% of cases were light infected, i.e. less than 4,000/EPG. The cercarial expulsion rate of 5,005 Parafossarulus sp. was 0.34%. Snails naturally infected with C. sinensis expelled about 788 cercariae/day. Ten of 18 species of freshwater fish examined had C. sinensis metacercariae. To prevent clonorchiasis in the endemic areas, the effective health education system is suggested as a control measure.
