Three experimental diets of 25, 30 and 35% crude protein designated as Low Protein (LP), Medium Protein (MP) and High Protein (HP) diets, 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±0.11 g were stocked in 12 plastic aquaria tanks of 65 L in capacity at 10 fish tank-1. Fish were fed twice daily at 3% b.wt. day-1. Fish fed continuously on HP had significantly (p<0.05) highest growth rate and feed utilization among treatments. However, there were no significant differences (p>0.05) in 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 showed that feeding C. gariepinus continuously with 35% CP diet is more economical than the mixed feeding schedule with LP and HP diets.]]>Ali, Z., A. Hossain and A.
