- From June to September, 1984, fresh-water fish "were collected in the river Dongchang running through Cheongdo county, Kyungpook Province, Korea.
Thirteen kinds of fish were collected by fishing, throwing a castnet, and using a glass bowl containing crushed oil-cake as bait, and examined for the infestation rates and intensity of infestation of the metacercaria of Clonorchis sinensis.
Of these, for kinds of fish, Acheilognathus limbata, Gnathopogon atromaculatus, Microphyso-gobio koreenszs， and Pungtungia herzit harbored the metacercaria of C. sinensis.
The infestation rate for the cyst was the highest in P. herzi， 100 per cent, followed by G. atromaculatus 81.8 per cent. The rates in M. Koreensis and A. limbata were relatively low, 42.9 and 30.0 per cent, respectively.
In intensity of infestation in the fish estimated by the number of larvae per gram of fish, the number of larvae in G. atromaculatus was extraordinarily high, 61.9, followed by P. herzi 22.9, and M. koreensis 2.6. The least number was A. limbata 0,9.
It was found that fresh-water fish caught in the river Dongchang were more infested with the metacercaria of C. sinensis Tkan the fish in the river Cheongdo, the same tributary of river Milyang.
