This research was conducted from December 2014 to February 2015. A Total of 40 fish samples from 7 species were observed, identified and then analyzed. Endoparasites found in the digestive tract was from the Family of Anoplocephalidae, Trichinellidae, and Strongyloididae with a value of 22.5% prevalence of endoparasites, with the category Often, whereas in scales and gills there were no ectoparasites. The value of the prevalence of endoparasites in each Family were 2.5% (Anoplocephalidae), 5% (Trichinellidae), and 15% (Strongyloididae). Endoparasites prevalence values for each fish species were 71% (Channa striata), 38% (Barbonymus schwanenfeldii), 17% (Osteochilus kelabau). Value prevalence of parasites in each organ of the digestive tract was 30% in stomach and 70% in bowel. Endoparasites intensity value was 1.1 while the value of the intensity of each Family were 1 (Anoplocephalidae), 1 (Trichinellidae) and 1.17 (Strongyloididae).enDistrict PelalawanEndoparasiticIntensityPrevalencestudent Paper Post Degree
