Formulation and Optimisation of Fish (O. niloticus) Feed from Food Waste Protein Source

The aquaculture industry is facing rising costs of conventional feed. Premium protein sources such as fishmeal and fish oil are highly price-volatile due to fluctuating supply and demand, and reliance on imported feed further increases costs. Another key challenge is the growing volume of food waste. A survey of local food processing companies conducted between August 2022 and June 2023 identified approximately 174,300 tonnes of homogeneous food waste, highlighting the scale of the problem. 

This technology offers a sustainable aquafeed solution by converting by-products from soy sauce production, fish processing, and bread waste into nutritionally balanced feed for tilapia (O. niloticus), maintaining optimal growth performance while reducing dependency on conventional, expensive feed ingredients. 

The technical specifications and features of the solution are as follows: 

• Processing: Transforms readily available soy press cake, fish processing waste and bread into aquafeed through low-shear mixing, fermentation, spheronization and pelletization. 

• Formulation: Provides feed formulation designed specifically for tilapia, incorporated with essential proteins, amino acids, carbohydrates, lipids, vitamins, and minerals. 

• Pellet properties: Produces water-stable sinking pellets with enhanced physical stability and controlled nutrient leaching properties 

• Quality control: Ensures consistency through physical profiling, nutritional analysis
