Circular Aquaculture through Black Soldier Fly Larvae Meal: A Sustainable Alternative Protein Source for Enhancing Aquaculture Productivity and Blue Economy Growth in Kenya

Aquaculture is one of the fastest-growing food production sectors globally and plays a critical role in supporting food security, livelihoods, and blue economy development. However, the increasing cost and limited availability of fishmeal, the primary protein source in aquafeeds, pose significant challenges to sustainable aquaculture expansion. Black Soldier Fly (BSF) (Black Soldier Fly) larvae have emerged as a promising alternative protein source due to their high nutritional value, efficient bioconversion of organic waste, and potential contribution to circular economy systems.

This study explores the potential of BSF larvae meal as a sustainable replacement for conventional fishmeal in aquaculture feeds within Kenya's emerging blue economy. Through a review of existing literature and current production systems, the study examines the nutritional composition of BSF larvae, environmental benefits associated with organic waste recycling, and implications for aquaculture productivity. The analysis further evaluates the role of BSF-based feed systems in reducing dependence on wild-caught fish resources while promoting resource efficiency and environmental sustainability.

Findings indicate that BSF larvae meal possesses substantial protein and lipid content suitable for aquaculture species and offers opportunities for reducing feed costs while enhancing circular resource utilization. Additionally, integrating BSF production with aquaculture systems can contribute to waste management, climate resilience, and sustainable livelihoods for small-scale producers. The study highlights policy, regulatory, and adoption considerations necessary for scaling insect-based feed technologies in Kenya.

The integration of BSF larvae into aquaculture feed value chains presents a viable pathway for advancing sustainable aquaculture, strengthening food security, and accelerating blue economy transformation. This approach supports environmentally responsible fish production while fostering innovation in circular bioeconomy systems.
