A total of 100 Clarias gariepinus (African Catfish) were purchased between April and June 2017 from Artisanal fishermen at River Gudi. Akwanga Local Government Area of Nasarawa State to determine the prevalence of gastrointestinal helminth parasites of Clarias gariepinus. The fish were subjected to parasitological study in Zoology Laboratory, Nasarawa State University Keffi.. Out of this 100 fish sample, 63 (63%) were infected and a total of 90 helminth parasites recovered. Three species of helminth parasites were isolated namely Camallanus (41%), Diphyllobothrium latum (29%) and Capillaria (20%).There is a significant different (p>0.05) in the infection rate of male and female fish. The highest fish organ infected was intestine (36%) follow by the stomach (33.3%), next was the oesophagus (23.3%) and finally Rectum (6.6%).There is a significant different in the gastrointestinal helminth parasites of Clarias gariepinus at different site of gastrointestinal tract (P< 0.05). The infection rate in relation to body length was highest 90.3% at 26- 30cm.There is a significant difference in the gastrointestinal helminth parasites of Clarias gariepinus in relation to body length (p<0.05) .Gastrointestinal helminth parasites probably capable of reducing the productivity of fish in River Gudi are hereby presented in the light of these findings.
