Abstract

Dactylogyrosis due to Dactylogyrus sp. occured among cultured sea bass (Lateolabrax japonicus) in Geoje, Kyoung Nam Prefecture in July, 1988. Descriptions are given of the opisthohaptor, copulatory organ and also of the structures in Dactylogyrus sp.. Dactylogyrus sp. have one pair of minute anchor (length : $15-22{\mu}m$) and 14 larger hooks. Histopathological changes of the heavily infested gills are showed necrosis, epithelium of the gill filaments underwent hyperplasia with fusion of the lamellae and filamental clubbing. And a bacterial colony is invaded on the surface of lamellar epithelium.

1. 1988년(年) 7월(月)에 해상(海上)가두리 양식장(養殖場)에서 농어에 기생(寄生)하는 Dactylogyrus sp.에 속(屬)하는 기생충(寄生蟲) 1종(種)을 얻었다. 2. 병리조직학적(病理組織學的) 소견(所見)으로는 호흡상피세포(呼吸上皮細胞)의 증생(增生), 비후(肥厚), 새박판간상피세포의 증생(增生)과 새변의 곤봉화(棍捧化)가 일어나 있었다. 3. 2차적(次的)으로 세균(細菌)의 감염(感染)에 의한 아가미부식(腐蝕)도 관찰(觀察) 되었다.
