Abstract: The purpose of this research was to determine the value of prevalence, intensity, and identification of Kerapu Epinephelus fuscoguttatus-lanceolatus fishes. This research has been held in April until May 2018 on the east coast of Pangandaran. The methods used in this research are survey methods, sampling and laboratory tests. The parameters observed were the prevalence and intensity values of ectoparasites that infect the fishes. Ectoparasites data that have been found were analyzed with prevalence and intensity analysis, analyzed descriptively. This research of ectoparasite analysis are divided based on the place of sampling. First sample taken at floating cage (FLOATING CAGE) quatec has a prevalence value of Diplectanum 66,6%, Tricodina 50%, Alitropus 11,1%. Intensity value of Diplectanum 2,9, Tricodina 3,7, Alitropus 2. For sample taken at FLOATING CAGE Traditional has a prevalence value of Diplectanum 44,4%, Tricodina 38,8%, Alitropus 33,3%. Intensity value of Diplectanum 2, Tricodina 1,6, Myxosporea 1,7.
