Study on infestation and dynamic of Anisakisis pathogen in marine fishes from Taiwan Strait

A nearly two years study on the infestation and dynamic of Anisakisis pathogen in marine fishes from Taiwan Strait was conducted. A total of 80 species of fishes was examined. Four species of parasitic nematode larvae, Contracaecum sp.(HC 5), Raphidascaris trichiur, Contracaecum muraenesoxi n. sp. and Anisakis simplex, which could be the pathogen of Anisakisis, appear in this area. Their infection prevalence are 54.32%, 16.05%, 32.10% and 21.16% of the examined fishes respectively. And they also have relatively high intensity of infection in some fishes, e.g. the mean intensity of the first two species in the body of Decapterus maruadsi is 46.25 and 28.78 respectively, and 47.14, 9.12 for the last two in Muraenesox cinereus respectively. The prevalence and intensity of infection of Anisakisis pathogen are not directly correlate with the seasonal variation of the temperature. The seasonal fluctuation and distribution of zoo-plankton, and the ecological and biological characteristics of fishes play important role in the dynamic of their infestion.
