The study of prevalence and mean intensity of metazoan endoparasites on redbelly yellowtail fusilier, caesio cuning

Abstract

Redbelly Y ellowtail Fusilier, Caseio cuning were obtained from Pulau Kambing, Kuala Terengganu and used for this project. A total of 6 species of metazoan endoparasites were collected from 30 specimens of fishes of the family Caesionidae, Caesio cuning from August 2008 to February 2009. The metazoan endoparasites obtained were as follows: i) lntuscirrus sp., ii) Dollfustrema sp., iii) Digenea sp., iv) Anisakis sp., v) Cucullanus sp., and vi) Acanthocephalan. The highest prevalence and mean intensity for metazoan endoparasites on Caesio cuning is Anisakis sp. which were found in digestive tract that is 60% and 7.9 (:::::: 8.0) of parasites per fish infected respectively. The second highest prevalence and mean intensity for metazoan endoparasite is lntuscirrus sp. was found in the stomach of Caesio cuning that is 57% and 6.3 (:::::: 6.0) of parasites per fish infected respectively. The relation between parasites, host, diet of the host is also discussed.
