Prevalence and intensity of Anisakidae larvae on Japanese anchovy caught along the Kagoshima coast were investigated. Among 2239 Japanese anchovy 153 were found to be infected with 342 of Anisakidae larvae. From the total of Anisakidae larvae 64% were identified as Rhaphidascalis spp. and 11% of them were identified as Anisakis simplex. Rhaphidascalis spp. were dominant in Anisakidae larvae from the coast of Hayato, Makurazaki and Uchinoura towns, A. simplex was dominant in those from Akune and H. fabri was only found on the fish from Makurazaki. Anisakidae larvae were mainly found on the pyloric caeca and gonads and the rates were 80.2% and 14.5%, respectively. There was a positive correlation between the body length of the fish and the intensity of Anisakidae larvae found in the fish. Generic compositions of Anisakidae larvae varied among four sampling sites and those might be brought about by the environmental conditions of waters such as the existence and the amount of intermediate and terminal hosts.
