The study on ectoparasite of lionhead goldfish

Abstract

This study was carried out to determine the mean intensity and prevalence of ectoparasites of lionhead goldfish (Carasius arratus). A total of 30 samples of lionhead goldfish were selected from ornamental fish shop at Gong Badak. The fish were maintained in aquarium, for examination in the laboratory. Examination of ectoparasites began with skin smear and gill smear. The result showed that only two parasites have been identified from group monogenea, Gyrodactylus sp and two Trichodina sp from group protozoa. Total samples of Trichodina sp. 1 (n=30) had been measured for the species identification. The prevalence and mean intensity of Gyrodactylus sp was recorded with 93.33% and 30.82 while Trichodina sp. 96.67% and 70.21, respectively
