Investigation on Transmitting Vectors of Anisakiasis

The investigation of Anisakis larvae infestation was car- ried out in 22 species of marine fish from Bohai and Huanghai along the China coast. Anisakis larvae were detected in 126 of 474 fish belonging to 17 species including Hexagrammos o- takii, Clupanodon punctatus, Scomberomorus niphonius, Pseu- dosciaena crocea, P. polyactis, Argyrosomus argentatus, Pneumatophorus japonicus, Trichiurus haumela, Pagrosomus major, Platycephalus indicus, Sebastes schlegeli, Engraulis japonicus, Hsmirhomphus sajori, Saurida elongata, Navodon modestus, Gadus macrocephalus, Liparis tanakae. The total number of larvae collected was 791. Higher detection rate and relatively heavier infestation as shown by the number infected each fish were examined. A number of larvae per specimen were found in 7 species of the fish including Pneumatophorus japonicus (11/14 ; 1-216 larvae), Gadus macrocephalus (3/3; 5-49), Trichiurus haumela (9/9 ; 1-35). The morphologic fea- tures were studied. The larvae observed were all of Anisakis type 1 third stage.
