Raising black soldier flies as sustainable feed for fish farms | The Protein Problem

When the fish grown in farms are fed wild-caught fish such as sardines and anchovies, a major benefit of fish farms — less stress on ocean ecosystems — can evaporate.  

At Innovafeed, based in France, protein-rich black soldier flies are being raised as a feed alternative. The company’s fly protein is feeding salmon, sea bream, shrimp and other species with food producers across Europe, the Americas and Southeast Asia, according to Alex Diana, a product manager at Innovafeed. It has two factories now and is planning 10 more by 2030 that will produce insect protein for fish, chicken and even pets.
