Abstract

From February through March 2002, sixteen rockfishes representing three species were collected from Oregon Coast Aquarium and Newport fish market and examined far nematodes. During this study, a total of 157 Anisakis type larvae were recovered from Sebastes spp. and parasitized for an average infection prevalence of 50.0%. The yellowtail rockfish, S. flavidus, darkblotched rockfish, S. crameri, and canary rockfish, S. pinniger examined were infected with 110 Anisakis simplex larva, 30 Contracaecum spp. larva and 17 Pseudoterranova decipiens larva. Of the rockfishes examined, 75.0% carried Sebastes crameri, and 12.5% S. flavidus and S. crameri, respectively. The sites of infection far Anisakis type larvae were the intestine, omentum, and stomach walls. A. simplex larvae infected 60.0% on S. crameri and 33.3% on S.flavidus and S. pinniger respectively. The prevalence of Contracaecum sp. larvae and Pseudoterranova decipiens larvae on S. pinniger was 33.3%. The intensities of A. simplex larvae ranged from 1 to 87 in S. flavidus, S. crameri, and S. pinniger. The intensity of Contracaecum spp. larvae and P. decipiens larvae ranged from 0 to 30 in S. pinniger.

2002년 2월부터 3월까지 오레건 주에 위치한 오레건 해안 수조와 뉴포트 어시장으로부터 16마리의 볼락류 Sebastes spp.를 채집하여 검사한 결과, 3종의 볼락류로부터 총 157개체의 아니사키스 유충이 검출되었으며 50.0%의 감염률을 나타내었다. 3종의 볼락류인 Sebastes flavidus, S. crameri, S. pinniger로부터 Anisakis simplex유충 110 개체, Contracaecum app. 유충 30개체 그리고 Pseudoteryanova decipiens 유충 17개체가 각각 검출되었다. 아니사키스 유충의 감염부위는 장관, 장간막과 위벽이었다. A. simplex 유충은 S. crameri에서 60%, S. flavidus와 S. pinniger에서 각각 33.3%의 감염률을 나타내었다. Contracaecum spp. 유충과 P. decipiens 유충은 S. pinniger에서 33.3%의 감염률을 나타내었다. A. simplex 유충의 감염강도는 5. flavidus, S. crameri 그리고 S. pinniger에서 1에서 87이었고 Contracaecum spp.유충과 P. decipiens 유충은 S. pinniger에서 0에서 30까지 나타내었다.
