虽然海鳗（Astroconger myriaster）在韩国被怀疑是人类茴香病最重要的鱼类宿主之一，但没有关于海鳗感染茴香病幼虫情况的报道。本研究在首尔芦梁津鱼市场购买了26只海鳗（Astroconger myriaster），并从其内脏、肌肉、头部和皮肤中采集了茴香幼虫。收集到的幼虫按形态类型分类。在26条鱼中，15条鱼共采集到1351条茴香虫幼虫。其中内脏1269条，肌肉66条，头部及皮肤16条。形态学上将大部分八角虫分为6种已知的幼虫类型：Berland（1961）的1型八角虫（564只），Koyama等（1969）的A型（409只）和D型（5只），Chai等（1986）的C′型（83只）和D′型（117只），Yamaguti（1935）的V型（1只）。其余172个标本为文献新发现标本，命名为A’型（新类型）。结果表明，在韩国海域捕获的鳗鱼幼虫不仅在内脏中感染，而且在肌肉中也感染了大量的八角线虫幼虫，在7种幼虫类型中，I型八角线虫最为常见。
Although the sea eel (Astroconger myriaster) is suspected as one of the most important fish host for human anisakiasis in Korea, no report has been made on the infection status of the sea eel with anisakid larvae. In the present study, 26 sea eels (Astroconger myriaster) were purchased from the Noryangjin fish market is Seoul, and anisakid larvae were collected from their viscera, muscle, head and skin. The collected larvae were classified by their morphological types. A total of 1,351 anisakid larvae were collected from 15 of 26 fish examined. Among them, 1,269 were recovered from the viscera, 66 from the muscle, and 16 from the head and skin. Morphologically, most of the anisakids were classified into 6 known larval types, Anisakis type 1 (564 larvae) of Berland (1961), Contracaecum type A(409) and type D(5) of Koyama et al. (1969), Contracaecum type C'(83) and type D'(117) of Chai et al. (1986), and Contracaecum type V(1) of Yamaguti (1935). Remaining 172 specimens were new in the available literature, hence, designated as Contracaecum type A'(new type). The present results revealed that the sea eels caught in the Korean waters were heavily infected with anisakid larvae, not only in their viscera but also in the muscle, and Anisakis type I was the most common among the 7 larval types.
