Comparative analysis of the proximate, mineral composition and energy level of five fish species, Clarias gariepinus, Lates niloticus, Sarotherodon galilaeus, Heterotis niloticus and Oreochromis niloticus, from Ero Reservoir, Ikun Ekiti, Ekiti State Nigeria, was carried out from July-September, 2017.  Analysis of the samples was carried out at the Central Science Laboratory, Federal University of Technology, Akure according to the AOAC Official Method. The nutrients have the following ranges:  Protein 60.03-81.59%; Fat 6.24-8.24%; Carbohydrate 1.80-12.52%; Moisture Content 11.32-13.54%; Ash 3.15-5.81%. Highest percentage protein and fat values (81.59% and 8.28%) were both recorded in Heterotis niloticus while Sarotherodon galileaus and  Orechromis niloticus have the least values of protein and fat respectively. Highest percentage values of ash and carbohydrate were recorded in Sarotherodon galileaus. Protein content of Heterotis niloticus, ash and carbohydrate contents of Sarotherodon galileaus differed significantly from other species studied (P>0.05). The energy levels of the species varied; highest level was observed in Oreochromis niloticus 1553.07 Kcal/kg while the lowest level was in Clarias gariepinus 1439.23Kcal/kg. The minerals tested have the following ranges; Calcium 18.54-19.65Mg/g, Potassium 18.54-22.47Mg/g and Phosphorus 93.10-102.33Mg/g. The pattern of mineral concentration of each species is in order P>K>CA. All the fish species are rich in crude protein, lipid, moisture and ash and they met the nutritional requirements for man.
