Response of Acacia sieberiana containing diet on growth indices and food utilization efficacy of Tilapia Oreochromis niloticus fingerlings

Author(s): Asaad H Mohamed, Duaa Elsabreen E Mohamed
Abstract: This study and for the first time, focused on untapped indigenous wild savannah tree, Acacia sieberiana for its nutritional values and benefits may generated for fish aquaculture. The effect of dietary protein from A. sieberiana incorporated meal e.g. 10, 15 and 30% inclusions were evaluated in the Nile Tilapia O. niloticus fingerlings. Specimens were kept in twelves hapa nets with 500 L capacity installed in concrete tanks for 40 days and the values of growth rate, feeding efficiency and protein efficiency ratio of O. niloticus fingerlings (2.30 g) were examined. Every 10 days interval, sampling were conducted with individual weight measurements, and survival were recorded. Interestingly, the highest weight gain was obtained with treatment group fed with 10% A. sieberiana inclusion in the diet. The best feed conversion ratio (FCR), specific growth rate (SGR, % day-1), percent weight gain (WG %) and feed efficiency rate (FER) were obtained with the fish fed 10% of A. sieberiana inclusion as well. The result of the growth indices on O. niloticus fingerlings shows a great effects among experimental groups, and the use of diet containing A. sieberiana meal e.g. 10% inclusion is appropriate for optimal growth and efficiency of feed utilization of O. niloticus fingerlings. The results obtained in this study may be due to the nutritional values that A. sieberiana possessed, where protein and mineral requirements are available in considerable amount.
