Morphological Classification and Infection Rate of Anisakid Larvae in Marine Fishes

한국산 해산어류의 Anisakid유충 감염률 및 형태학적 분류

Anisakiasis occur after the ingestion of raw marine fish and squid containg anisakid larvae. In recent years about 40 cases of anisakiasis have been recorded in Korea. Considering, however, the Korean style of eating raw fish, many more cases would exist and prevention is necessary. We describe the infection rate of anisakid larvae in 13 species of marine fish and squid which were caught in the Korean sea. And each extracted larva is classified according to morphological characters. The results are following ; Scomber japonicus, Pseudosciaena manchurica, Trichiurus haumela showed high infection rate of anisakid larvae. Although Sepia esculenta showed low infection rate, most of anisakid larvae found in Sepia edulis are embedded in muscles. So relative high frequent rate of anisakiasis may developed by Sepia esculenta. Five type (Anisakis Type I, Terranova Type B, Raphidascaris sp., Contracaecum Type A, Contracaecum Type D) of anisakid larvae are classified according to their morphological characters.
