Abstract

Seventeen metazoan parasites were recovered from Sebastes crameri collected from Newport fish market. Nine Trochopus australis and 8 Neobrachiella robusta were found on gill arches of canary rockfishes. The commonest sites of metazoan parasites were the posterodorsal region and second gill arches of Sebastes crameri. T. australis were most commonly found on the second gill arches, but in N. robusta. the first gill arches were the most frequented position. No N. robusta were discovered on the fourth gill arch. Metazoan parasites infected gill arches I, II, and posterodorsal regions of S. crameri, occurring less frequently on the gill arches III, IV anteriorventral and middle regions.

뉴포트 어시장에서 채집한 볼락류인 Sebastes crameri로부터 17개체의 아가미 기생물을 발견하였다. 그중 9개체는 단생흡충류인 Trochopus australis이고 나머지 8개체는 요각류인 Neobrachiella robusta였다. 이 기생물의 가장 많이 발견되는 부위는 볼락류의 제 2 아가미새궁과 배측 후부였다. 단생류인 T. australis는 주로 제 2 아가미 새궁에서 요각류인 N. robusta는 제 1 아가미새궁에서 발견되었으나 요각류는 제 4 아가미새궁에서는 발견되지 않았다. 이번 연구에서 기생물의 아가미 부착은 주로 제 1, 2 새궁의 배후측에, 그러나 제 3, 4 아가미새궁의 전복측과 중앙에는 적게 분포되어 있었다.
