Abstract

Cercarial contamination (being suspected as a gasterostome trematode, Bucephalidae: Digenea) in the Yodo River was studied by the water monitoring using experimental fishes. The fishes including <i>Pseudorasbora parva</i> and <i>Squalidus chankaensis</i> subsp. were exposed in the river and the cercariae that penetrated tail fin of the fishes were observed with a stereoscopic microscope. The monitoring was carried out three times from December 2000 to January 2001 in the Yodo River. Over 80% of the fishes were infected by the cercariae (average numbers of metacercariae in an infected fish ranged from 5.2 to 18.1) during 4 to 10 days of the exposure. The numbers of cercariae in the river water were estimated to be 0.12 to 1.72·m<sup>-3</sup>.
