The optimal feeding rate and water temperature for red hybrid tilapia fingerlings were
examined in this study. A feeding trial was conducted at different feeding rates
(3,5,7%) with feed contained 43% crude protein whereas the second set of
experiment was performed at different water temperature (i.e.28˚C, 30˚C, 32˚C ).
Both experiments were conducted for 10 days. The results for the first experiment
revealed that there were significant differences in 4 out of 6 growth performance
parameters of weight gain, specific growth rate, daily weight gain and final body
weight (P˂0.05) while no significant difference in feed conversion ratio and
percentage weight gain (P˃0.05). The best growth performance was recorded with
feeding rate of 7%. The results for the second experiment showed that there were no
significant differences in all growth performance parameters and feed utilization
(P˃0.05). These findings suggest that feeding rate of 7% within the temperature
range of 28˚C to 32˚C can be utilized for optimal growth performance during red
hybrid tilapia fingerlings rearing.
