AB  - A-56 day growth trial was conducted to investigate the effect of mixed feeding schedules of different dietary crude protein levels on growth and feed utilization of fingerlings of <I>Clarias gariepinus. </I>Three experimental diets of 25, 30 and 35% crude protein designated as Low Protein (LP), Medium Protein (MP) and High Protein diet (HP), respectively were prepared using locally available feed ingredients. Four different feeding schedules of High-Protein diet continuously (HP), Medium-Protein diet continuously (MP), Low-Protein diet continuously (LP) and mixed feeding of 1 day Low-Protein/1-day High-Protein (1LP/1HP) were tested. Fingerlings of mean weight 1.24&plusmn;0.11 g were stocked in 12 plastic aquaria tanks of 65 L in capacity at 10 fish/tank. Fish were fed twice daily at 3% body weight day<SUP>-1</SUP> and adjusted biweekly according to changes in weight of fish. Fish fed continuously on HP resulted in significantly (p&lt;0.05) the higher growth rate and feed utilization among treatments. However, there were no significant differences (p&gt;0.05) between the growth rates and feed utilization of fish fed 1-day Low-Protein/1-day High-Protein (1LP/1HP) and those fed continuously on MP. Fish fed continuously on LP had the least growth and feed utilization. This study show that feeding <I>C. gariepinus</I> continuously with 35% CP diet is more economical than the mixed feeding schedule of alternate day feeding of LP and HP diets.
