1998년 3월부터 2000년 4월까지 전라남 북도 및 충청남도 일원의 내수면 양식장에서 사육중인 잉어(Cyprinus carpio)와 미꾸리(Misgurnus anguillicaudatus)를 채집하여 아가미에서 3종의 단생흡충류를 검출하였다. 검출된 단생 흡충류는 잉어에서는 Dactylogyrus extensus(Mueller and Cleave,1932)와 Diplozoon niponicum(Goto, 1891)을, 미꾸리에서는 Gylodactylus paralatus(Gussev,1955)가 검출되었다. 이들 단생흡충 중 Dactylogyrus extensus와 Gylodactylus paralatus는 국내에서는 처음으로 보고되는 종이다.
Monogeneans(Phylum Platyhelminthes) have been known as common parasites onto the skin and gills of cultured freshwater fishes. Infestation with these parasites result in a great loss in aquaculture industry. Some classification studies on these parasites have mostly been conducted in Japan but rarely in Korea. For the purpose of classifying monogenean parasites infesting two Korean freshwater fishes, carp(Cyprinus carpio) and loach(Misgurnus anguillicaudatus), samples captured from March 1998 to April 2000 were examined. Here we report that three different species of Monogeneans, Diplozoon nipponicum, Dactylogyrus extensus from carp and Gyrodactylus paralatus from loach, respectively. Of these the latter two parasites have never been identified in Korea.
