Fish parasite cause high mortality and lower the general health of fish, thus reducing the economic value and leading to zoonotic disease. This study is to determine the prevalence of end parasite of Nile Tilapia (Oreochromis niloticus) sold for consumption at Igbokoda River, Ilaje Local Government area of Ondo State. Fish purchased from Igbokoda was transported to the Department of Biology Laboratory, FUTA, and was sacrificed, measure and dissected to reveal the vital organ for parasite examination. Of the 200 sample of Tilapia examined, 84 (42%) were infected. The most prevalent parasite was Diphyllobothrium latum with prevalence of 32 (38%) followed by Camallanus 20 (23.8%), Gnathostoma spinigerum 14 (16.67%), Procamallanus 10 (11.9%) and Clinostomum with the lowest prevalence of 8 (9.52%). Fish with body weight greater than 300g and those having longer length were more infected and have the highest prevalence of 100% and 24 (60%) respectively. There was significance between the weight and length of the fish with respect to the fish parasite prevalence (P < 0.05). thus this study reveal that fish parasite is still prevent in the study area and as such urgent control intervention should be designed to curb these parasites.
