Infection Status of Todarodes pacificus (Mollusca: Cephalopoda) with Anisakid Larvae in the Markets from Jumungin

주문진 어시장 살오징어(Todarodes pacificus)의 아니사키스 유충 감염상

A total of 248 specimens of Todarodes pacificus were purchased from the Jumungin fishery market at the East Sea area two times during the period from November 1 to December 30, 1995. Samples were examined for their infection status with larvae anisakid. Anisakid larvae were collected from muscle, viscera and omentum. One hundred sixteen larval anisakids sorted from 34 specimens of T. pacificus (13.7% of infection rate) ranged from 13.5 to 29.5 mm in their body length. They were classified based on morphological and morphometric observations as follows; Anisakis type I larvae (68 larvae, 58.6%: positive rate), Contracaecum type A (5, 4.3%), Anisakis type II (17, 14.5%), Contracaecum type D (8, 7.0%) and unknown type (18, 15.5%).

1995년 11, 12월에 동해안 주문진 어시장에서 구입한 살오징어(Todarodes pacificus) 248개체중 34개체로부터 116개체의 아니사키스 유충이 채집되어 13.7% 의 유충 감염율을 나타내었다. 형태 및 크기를 바탕으로 유충의 종류 및 근육, 내장, 망 등 어체 부위별 감염상황을 조사한 결과 유충의 길이는 13.5-29.5 mm 이었으며 Anisakis type I이 68개체 (58.6%:회수율), Contracaecum type A 5개 체 (4.3%), Anisakis type II 17개체 (14.6%), Contracaecum type D 8개체 (7.0%) 및 불명 18개체 (15.5%)로 분류되었다.
