Black soldier flies in aquaculture

Around the world carnivores such as salmon and tuna live on a fishmeal diet. This seemingly innocent matter has just recently resulted in an ever-growing problem concerning their feed in aquaculture. Many smaller species are not intended for direct consumption but bred purely to be fed to other animals. More precisely, this problem mostly concerns the so-called “reduction fisheries.” They process their catch into fishmeal and are only interested in species lower in the food chain, such as sardines or anchovies; those which would otherwise be treated by wild carnivores as a primary food source. As the demand grows, black soldier flies come to the rescue of aquaculture.

Hermetia illucens – a “bug” which has changed the industry

The BSF, meaning the black soldier fly, is commonly known to be one of the most beneficial insects in the world. Due to a high protein content they are used in composting and moreover, for years they have been a feed for animals.

Fishmeal replacement for conventional aquafeed

Black soldier flies can replace fishmeal in the diets of many aquatic species with remarkable success. For example, research show that salmon and trout grow as fast on a BSF diet as on their usual one. Moreover, the meal swap has not had any negative effects on the people who ate those animals. Interestingly, feeding salmons with larvae did not hinder the quality (nor taste and texture) of the finished products destined to eat, such as fillets. The replacement did not also affect liver traits nor the sensory qualities of the fillet.

Answer to your needs

BSF has revolutionized the industry. They are high in protein, calcium, and many amino acids. Using black soldier flies in aquaculture provides fish with enough nutritional value for their proper development.
