Title: Effects of Different Feeding Rates on Growth Performance and Body Composition of Red Tilapia, <i>Oreochromis mossambiquse x O. niloticus</i>, Fingerlings
Abstract: In aquaculture feeding rate is an important factor affecting the growth of fish and thus determining the optimal feeding rate is important to the success of any aquaculture operation. The aim of this study was to determine the optimal feeding rate for red tilapia ( Oreochromis sp.). A 12-week feeding trial was conducted to examine the effects of different levels of the feeding rates on the growth performance and body composition of red tilapia, ( Oreochromis sp.). Fish of an average initial weight of 0.9±0.01 g were stocked in 12 glass aquaria (80 L each) at a rate of 15 fish per aquarium. All fish were fed the same diets contained 33.8% crude protein at a feeding rate of 1, 3, 5 and 7% of body weight daily. The results revealed that there was a significant differences in growth performance and feed utilization parameters with increasing feeding rates up to 5 % (P 0.05) by feeding rates. Lipid and ash contents were significantly (P < 0.05) influenced by feeding rates. These findings suggest that feeding rate of 5% of body weight daily can be considered as the optimal feeding rate for red tilapia fingerlings which significantly enhance fish growth, feed utilization and body composition parameters.
