Insect larvae meals are considered a very promising alternative to provide valuable proteins for aqua feeds1 and food2. Insects are highly nutritious, convert feed efficiently to body mass, can be grown on organic side-streams and agricultural by-products, whereas their rearing is described by low water and land requirements and reduced gas emissions3. The European Commission approved the use of processed animal protein from seven insects in feeds for aquaculture and their use is expected to dramatically increase4. Although high levels of insect larvae meal inclusion in fish feeds could lead to a slight decrease of juvenile fish performances, recent studies reported positive results in gilthead sea bream (Sparus aurata)5 and in crustaceans6. Feeding on selected substrates exerted an impact on the nutrient composition of Tenebio molitor larvae, with a high protein content of the substrate usually resulting in a high protein content of the larvae7. Further research is needed to gain knowledge regarding its use as an insect-based protein provider for feed and food.
