Abstract

Abstract: Research has been conducted on the difference in intensity value and prevalence of tilapia ( Oreochromis niloticus ) ectoparasites in ponds with low, moderate and high density in February to March 2018. This study aims to identify ectoparasite species and calculate the prevalence and intensity of ectoparasites maintained in solid low, medium and high stocking. Based on the results, the parasites were Trichodina nobilis, Dactylogyrus sp, Gyrodactylus sp and Oodinium sp. The highest prevalence values were found in low stocking densities of 100% including the very severe category and the highest intensity was 158.95 individuals/tail. The lowest prevalence values were found in medium and high stocking density of 78.3% and 70% included in the usual infection category and the highest intensity values had a value of 2.45 and 4.97 individuals/tail.
