Title : Feed formulation from locally available ingredients as replacement diet of commercial feed for growth performance of Nile tilapia, Oreochromis niloticus (Linnaeus, 1758) in concrete pond culture system, southwest Ethiopia

Abstract:

Aquaculture in Ethiopia remains more potential than actual practice; despite the fact that the country’s physical and socio-economic conditions support its development. A 90 days experiment was conducted to compare the performance of two locally formulated feeds as possible replacements for expensive commercial feed used for rearing of Nile tilapia. Randomized complete block experimental design was used. Each block has four treatments with two replicas. A total of 192 fingerlings were obtained from Sebeta fishery and aquatic life research center and stocked at a rate of 2 fish per m² to all experimental ponds. All growth performance parameters such as weight and length were measured using electronic balance and measuring board respectively during experiment at every 15 days. All physicochemical characteristics of the water were monitored to the recommended range for fish growth. The highest mean final weight was recorded in CF (73.88±25.11) followed by FF2(65.02±12.50) then FF1(52.62±15.97) and control(38.50±9.81).The highest final mean length was also recorded in CF(15.04±1.72) followed by FF2(14.50±1.15) then FF1(13.31±1.43) and control(12.28±1.34).Whereas one way ANOVA compare mean weight and length and the Post hoc test output revealed that there was significant difference (p< 0.05) between CF, FF1 and Control fishes being higher CF followed by FF1 and control in growth performance. Despite higher growth performance was recorded in commercial feed meal (CF) there was no significant difference (P>0.05) between CF and FF2. The most appropriate formulated feed with better growth performance and candidate to replace the commercial fish feed is locally formulated feed two (FF2) which composed of Soya Bean, Common Bean, Sorghum bran and poultry manure. Therefore, the conceptual framework assumes that different feed formulations influence the growth performance of Nile tilapia, and locally formulated feeds may provide comparable growth results to commercial feeds if they contain adequate nutrients.
