SUMMARY
The aim of this study was to determine and compare the proximate composition of Oreochromis niloticus and hybrid Tilapia, from Oyan Lake. Â Parameters proximate composition which includes protein, lipid, ash and moisture content were estimated. The average moisture content for O.niloticus was in range of 81.11 to 81.67% and 80.01 to 80.17% for hybrid Tilapia. %. Results revealed that there was a significant difference in the mean protein values of O.niloticus and hybrid tilapia with the females of the two fish species were observed to have significantly higher (p <0.05) crude protein content than their male counterparts. The fat content values were low but significantly different (p<0.05) between the hybrid Tilapia and O.niloticus. Ash content ranged from 1.24 to1.48% for the O.niloticus and 1.30 to 1.24% for the hybrid Tilapia.
