The Black Soldier Fly continues to lead the field in insects as animal feed production.
Most of the salmon that consumers eat is raised in pens, where they are fed a specific diet that helps them grow. In the past, much of that diet has been based on fish meal, a protein and nutrient-rich mixture made from fish that were caught expressly for the purpose of feeding them to other fish. That practice has drawn criticism from conservationists, however, who point out that it’s an inefficient process that contributes to overfishing and the bycatch of sensitive marine organisms like whales and sea turtles.
Salmon, which are notoriously picky, liked the food made from the black soldier flies better than the other alternatives. Because salmon can take up to two and a half years to mature, and because most new types of feed are only tested for a couple of months, there is often reluctance in the aquaculture industry to try new kinds of feed, says Aarts. In an attempt to attract interest, Protix tested the new insect-based food for four years.
