Inclusion of Black Soldier Fly (Hermetia illucens) meal in the nutrition of fish and crustaceans

Abstract

The growth of the aquaculture industry has been driven by the increasing global demand for food and concerns about the overexploitation of natural resources and environmental impact. To address these challenges, aquaculture has sought sustainable and innovative alternatives. In this context, the inclusion of insects, such as the Black Soldier Fly (Hermetia illucens), in the diet of fish and crustaceans emerges as a promising solution due to their high protein, lipid, and mineral content. This review article discusses the role of Soldier Fly meal in aquaculture. It examines the economic, nutritional, and environmental benefits of meal in aquatic animal diets, as well as recent research results on proper dosage, growth quality, gut health, and nutrient availability in various aquaculture species. It is emphasized that Black Soldier Fly meal offers nutritional benefits comparable to fish meal, being a rich source of protein and lipids, and its inclusion in the diet of aquatic species such as fish and crustaceans has shown improvements in growth, health intestine and the quality of the final products. Despite these advantages, it is noted that complete replacement of fishmeal with insect meal is not the ultimate solution, as challenges related to regulation, mass insect rearing, and nutrient composition may arise. However, Black Soldier Fly meal stands out as a valuable alternative to diversify and improve feed sustainability in the aquaculture industry, contributing to food safety and care for the environment.
