조피볼락, Sebastes schlegeli 소화관 주변에는 다수의 아니사키 스가 기생하고 있었으며, 몇몇 개체들은 간의 표면에 존재하고 있었다. 유전학적 결과 조피볼락에 기생한 아니사키스는 3종으로 분석되었으며, Hysterothylacium sp.가 가장 많이 분포하고 있었다. Hysterothylacium sp.는 Anisakis simplex보다 짧고 가늘었다. 두 종 모두 전방부분에는 lip, 입, 신경환, 분비공, 분비관이 관찰되었다. 두 종 모두 중간부분에는 식도, 위, 장이 존재하고 있었 지만, intestinal ceacum과 ventricular appendage는 Hysterothylacium sp.에서만 관찰되었다. Hysterothylacium sp.의 후방부분 끝에는 conical nodulose apex이 관찰되었지만, A. simplex의 후방부분 끝에는 spine이 관찰되었다. SEM으로 관찰한 결과 Hysterothylacium sp.의 입 주위에는 3개의 lip이 존재하고 있었는데, dorsal lip은 넓이 65 ${\mu}m$ 내외였고, 한쌍의 lateroventral lip은 넓이 60 ${\mu}m$ 내 외였다. Lip의 표면에는 넓이 8 ${\mu}m$ 내외의 유두돌기 한쌍이 존재하고 있었다. Hysterothylacium sp.와 A. simplex의 충체 넓이는 각각 480 ${\mu}m$와 900 ${\mu}m$ 내외로 측정되었다. Hysterothylacium sp. 의 lateral alae는 높이 7 ${\mu}m$ 내외였으며, cornical nodulose apex에 존재하는 돌기는 지름 약 3.3 ${\mu}m$였다. A. simplex의 후방부분 끝 에는 높이 약 20 ${\mu}m$의 spine이 관찰되었다. 조피볼락 장의 내강 에 존재하는 아니사키스들은 대부분 Hysterothylacium sp.였고, 점막주름 근처 혹은 점막하층에 기생하고 있었다. 아니사키스의 기생으로 인하여 숙주의 점막상피에는 다수의 점액세포가 증가하였다.

다국어 초록 (Multilingual Abstract)

Numerous anisakids were parasitic near the digestive tract of the black rockfish, Sebastes schlegeli and some anisakids observed on the liver of the host. Anisakids in the host were identified three species (Hysterothylacium sp., Anisakis simplex, A. pegreffii) and Hysterothylacium sp. was the high occurrence of anisakid worms in the host. Hysterothylacium sp. was shorter and thinner than A. simplex. Both of anisakids observed lip, mouth, nerve ring, excretory pore and excretory duct in the anterior portion. In the mid portion, anisakids had esophagus, ventriculus and intestine and especially, Hysterothylacium sp. had intestinal ceacum and ventricular appendage. There was conical nodulose apex at the end of the posterior portion in Hysterothylacium sp. and spine in A. simplex. SEM examination revealed that there was three lip near the mouth of Hysterothylacium sp. Dorsal lip was approximately 65 ${\mu}m$ and paried lateroventral lip were approximately 60 ${\mu}m$ in the width. All lips were found double papilla (approximately 8 ${\mu}m$ in the width). The body width of the Hysterothylacium sp. and A. simplex was approximately 480 ${\mu}m$ and 900 ${\mu}m$ respectively. The hight of the lateral alae was about 7 ${\mu}m$ and width of papilla on the cornical nodulose apex was about 3.3 ${\mu}m$ in Hysterothylacium sp. The hight of spine was approximately 20 ${\mu}m$ in A. simplex. There was mainly Hysterothylacium sp. in the intestinal lumen of the host. The nematod worms were parasitic near the mucosal fold and in the submucosal. In the mucosal epidermal layer, it was increased mucous cells by the infection of the parasites.
