Abstract: Oba reservoir lies between Latitude 8° 3" N to 8° 12" N and Longitude 4° 6" E to 4° 12" E in Ogbomoso, Oyo state, Nigeria. Investigations were carried out between November 2011 and October 2013. Studies on morphometric, food, and feeding habits and enteroparasites of Sarotherodon galilaeus (Linnaeus, 1758) were done using standard methods. Ten types of food items were exploited by adults S. galilaeus while immature exploited six. In immature, insect parts had the highest frequency of occurrence (92.31 %), while in matured diets, Copepods were highest (78.21 %). The fish species was generally observed to be omnivores, but were primarily carnivores. Parasites recovered from the enteron were Neoechinorhynchus rutili, Acanthocentius tilapia, Clinostomum tilapia, Procamallanus laevionchus and Paracamallanus cyathopharynx;no parasite was found in the stomach. Parasitic prevalence was season and sex dependent, intensity was season dependent, and there was no relationship between parasite burden and fish size.
