Abstract

The gills of seven black rockfish, Sebastes melanops collected from Hatfield Marine Science Center Aquarium during September 19-October 3,2001 were examined for parasites attached to the gills. The species of Sebastes melanops were Microcotyle sebastis baled on the number of clamps and testes. The prevalence of 42.9％ was recorded for host and fourteen worms of three black rockfish were recovered. Mean intensity of infection of Microcotyle sebastis individuals per infected host for black rockfish was 2.0(range 1-11). Monogenea helminth sites were mainly consist of second and third gill arch's filaments of black rockfish. The results revealed that surface area of the 2nd and 3rd pair of gills might affect the distribution of Microcotyle sebastis.

2001년 9월 19일부터 동년 10월 3일까지 Hartfield Marine Science Center Aquarium에서 구입한 볼락류 Sebastes melanops 7마리의 아가미에 부착한 단생 흡충류를 조사하였다. 파악기와 정소 수를 근거로 한 불락류(S. melanops)의 단생 흡충류는 Microcotyle sebastis였다.M. sebastis의 감염률은 42.9%이었고 감염강도는 1-11(평균 2.0)을 나타내었다. 단생 흡충류의 감염부위는 주로 감염어 아가미의 제 2차와 제 3차 새변이었다. 따라서, 아가미의 제 2차와 제 3차 새변 표면은 M. sebastis의 분포에 영향을 끼치고 있음을 알 수 있었다.
