title: [Infection status of larval anisakids in Astroconger myriaster collected from the Southern Sea near Pusan].
abstract: A study was presented on the anisakid larvae in Astroconger myriaster which were caught at the Southern Sea and saled at Pusan area. The nematodes were morphologically classified into Anisakis sp. and Contracaecum sp. after fixation in 70% ethanol and clearing in lactophenol. Total of 1,768 larval anisakids were collected from 259 (67.8% positive rate) out of 382 examined A. myriaster. Total 642 larvae of Anisakis sp. were obtained from 94 (24.6%) and 1,126 Contracaecum sp. were recovered from 165 (43.1%) fish. The average number of worms per infected fish was 4.6. The infection rate increased according to the length of fish, and all of the fish over 71 cm were found infected. The numbers (proportions) of recovered worms by the organs were 1,440 (80.5%) in the omentum, 166 (9.4%) in the intestine, 107 (6.0%) in the stomach, 32 (1.8%) in the skin, 18 (1.0%) in the muscle, 13 (0.7%) in the liver, and 2 (0.1%) in the head. The larvae in the muscle may infect the humans who are enjoying raw sliced meat of the fish.
