| Research Abstract |
We investigated at 116 sites in Thailand, 18 sites in Korea and 84 sites in Japan. Nineteen trematodes were found from 35 species of snails. The highest diversity of snails was recorded at Gabei in Nago city (7 species), and that of trematodes (6 species) at Geppo-ri. Infection rate of snails was highest in Thailand (100%), and at Yamazaki in Hamamatsu city (80%). Tidal flats around Mokpo in southern Korea had high diversities of snails and trematodes. The diversity-rarity index was defined and calculated. The value was highest at Gabei, and were high at the small tidal flats in Kagawa and Saga Prefecture. Therefore it is suggested that the small tidal flats with good natural conditions are very important for survival of trematodes and their parasitc trematodes.
