Abstract

On September in 2010, myxosporidian parasites were found on the fins of Chinese muddy loach, Misgurnus mizolepis, Several cysts of approximately 2 mm diameter were observed on the fins. Numerous spores were found in the cyst. The total length of the spore was 13.0 to 15.8 ${\mu}m$, and the width of spore was 6.0 to 7.5 ${\mu}m$. As the results, the myxosporidians were finally identified as Thelohanellus misgurni (Kudo, 1919) on the basis of the presence of characteristic cysts and size of spores.

2010년 9월에 서해안 지역에서 양식중인 미꾸라지 중체표와 꼬리지느러미에 직경 약 2mm 크기의 유백색 포낭이 여러 개가 형성되어 상품으로 보기 흉한 미꾸라지 1미를 발견하여 포낭을 조사한 바, 점액포자충, Thelohanellus misgurni (Kudo, 1919)의 기생에 의한 것으로 밝혀졌다. 가슴지느러미 기부와 꼬리지느러미에 다량의 포낭이 형성됨으로써 지느러미의 가능을 할 수 없기 때문에 병어는 점차 쇠약해져서 폐사 될 것으로 사료된다.
