An epidemiological survey was performed to know the infection status of heterophyid fluke metacercariae in the brackish water fishes purchased from a local market in Haenam-gun, Chollanam-do, Korea from November to December, 1991. A total 20 out of 30 shads (Konosiw punctatus) examined were infected with the metacercariae of H. continua (average number of larvae per an infected fish: 2.71). Of 20 perches (Lateolabroxjoponicurs), 19 were Infected with the metacercariae of H. continua (average number per an infected fish: 17.21. Of 30 mullets (Mugil cepholus) examined, 11 were Infected with the metacercariae of H. nocens (average number per an Infected fish: 51.5), 10 mullets harboured 31 and 349 metacercariae of f summa and 5. lucatum respectively. Of 30 gobies (Acnnthogobin jlcvimonus) examined, 3 were infEcted with the metacercariae of H. nucens (average number per an Infected fish: 32.0), 8 with those of H. continua (average number per an infected flesh: 12.6) and 3 with those of 5. JuscntuwL From the above results, It has been confirmed that the brackish water Ash from Haenam-gun, Chollanam-do are infected with numerous metacercarlae of H. nocens, H. continua, P. summo and S. fuscatum Key words: Heterophyid fluke, metacercariae, infection status, brackish water fish, Haenam-gun , Heterophyes nocens, Heterophvopsis continua, Pygidiopsis summa, Stictodora fuscatum
