Do insect-based feeds affect the taste and quality of farmed fish meat?
The taste of fish meat from animals fed with Hermetia illucens-based diets does not differ from those receiving traditional complete feed mixes. There is also no observed impact on the texture or structure of the meat. These results are confirmed both in laboratory tests and in consumer panels, where participants report consistent eating experiences.
What are the effects of insect-based feeds on fish health and growth?
When used properly, insect-based feed components in fish nutrition can deliver strong growth performance: higher weight gain, improved growth rate, and reduced FCR. The key lies in balancing the feed appropriately and understanding the physiology of the species, as results vary between fish species. Additionally, the functional compounds found in insects benefit fish health, through hepatoregulation and modulation of gut microbiota, which translates into stronger immunity during critical rearing phases.
Can insect-based feed materials replace fishmeal in farmed fish diets?
Absolutely yes – and this applies not only to fishmeal but also to soy-based components. It’s worth noting that many fish species naturally feed on insects in their natural habitat, especially during the early stages of life as fry, which makes insect-based feed materials a kind of reconnection with nature. Both defatted and full-fat meals from Hermetia illucens work perfectly as components in aquaculture diets. From our perspective, the most important factor is the unique fatty acid profile, particularly the high lauric acid content. Insect-derived raw materials are also more sustainable and help reduce excessive environmental exploitation.
