Proceedings of the Chuka University 9th Annual International Research Conference held in Chuka University, Chuka, Kenya from 24th to 25th November, 2022. 34-42 pp.https://repository.chuka.ac.ke/handle/123456789/17596The world fastest-growing industry for producing food is aquaculture contributing to food security. Aquaculture is currently thought to provide 50% of the food fish needs, and by 2030, it's anticipated that this percentage will increase to 60–70%. Due to the cost and food-feed competition, the use of fish meal in aquaculture is progressively becoming unsustainable; therefore, there is a need to look for an alternate protein sources. The scarcity and the prohibitive cost of the fish meal renders the fish feed expensive, halting the growth of the sector, therefore an alternative protein sources which is cheaper and sustainable to relief overreliance on fishmeal and insects such as the Black soldier fly (Hermetia illucens). The black soldier fly (BSF), Hermetia illucens, is one of these insects that has a high protein and fat content and the micronutrients increasing its potential for use in the formulation of aqua feed. Both the protein content and the amino acid composition in H .Illucens larvae are comparable to those found in numerous protein-rich foods including fish meal. BSF has the capacity to convert organic waste into a rich supply of nutrients, including proteins, lipids, micronutrients and chitin, helps to lessen the strain on the environment and the possibility for pollution resulting from the buildup of organic waste. This review shows black soldier fly larvae as a substitute protein source in fish feed. The study recommends the farmers to adopt the use of BSF larvae meal in poultry keeping.enAquacultureBlack soldier fly and Fish-feedArticle
