In recent years, the cost of feeding ingredients has increased drastically, causing the price of animals to become higher. To solve this problem, fish wastes were used as an alternative ingredient in aquaculture feed formulation. The objectives of this project were to formulate fish silage from fish wastes by using lactic acid fermentation (Lactobacillus plantarum) for aquaculture feed formulation, to evaluate the nutritional composition of the fish wastes as an alternative ingredient for the aquaculture feed production, and to investigate the effect of experimental diets formulated on the animal model. The fish silage was carried out using a fermentation procedure by lactic acid fermentation (L. plantarum). In this study, 112 tilapia’s fingerlings were used and cultured into 4 compartments with different concentration of fish waste, the experimental diet of Fish waste 30% showed the highest increment in CP (36.527) compared to the other treatment. Fish waste 30% shows the lowest FCR (1.39) and high survival rate (92.86%). In the ADC% analysis, Fish waste 30% shows a higher increment in CL (22.82%) and lowest CF (6.27%). Fish waste experimental diet with 30% inclusion exhibited the best performance on body weight gained (0.36 g) with significant difference (P<0.05) recorded compared to control treatment (0.34 g). This showed that the fish waste has better potential to be used as main protein source in the aquaculture feed formulation.
