The project offers a competitive advantage through the incorporation of concentrated microalgae, which serves as a sustainable and cost-effective alternative to fishmeal. The ingredient provides higher levels of protein and essential fatty acids, supporting improved fish growth and health. Additionally, it acts as a natural binder, enhancing pellet stability. This reduces production costs while maintaining nutritional quality, addressing both economic and environmental concerns in aquaculture feed production.

This project introduces the use of microalgae cells as a sustainable ingredient in fish pellet formulation to improve nutritional value, particularly by enhancing protein and essential fatty acid content that supports the growth and survival of cultured fish. Traditional fish pellets rely heavily on fishmeal or land-based plant ingredients. While fishmeal increases production costs and contributes to over-exploitation of marine resources and climate change, land plant ingredients may cause digestion issues in fish. The integration of microalgae offers a cost-effective, digestible, and environmentally friendly alternative that supports sustainable aquaculture practices.

The solution involves incorporating concentrated microalgae cells into fish pellet formulations. These microalgae not only enhance the nutritional content—particularly proteins and essential fatty acids—but also act as a natural binder, improving the physical stability of the pellets. By partially replacing fishmeal with microalgae, the formulation reduces dependency on marine resources, lowering production costs and environmental impact, while avoiding digestion issues associated with land-based plant ingredients.

The innovation lies in the use of concentrated microalgae cells as a dual-purpose ingredient in fish pellet formulation—serving both as a high-quality nutritional supplement and a natural binder. This approach enhances the protein and essential fatty acid content of the pellets while improving their physical stability. It also allows for the partial replacement of fishmeal, reducing reliance on costly and unsustainable marine resources. This novel formulation supports cost-effective fish culture operations without compromising the nutritional requirements essential for healthy fish growth and survival.
