Black soldier fly larvae for sustainable animal feed

Protein-rich feed from black soldier fly larvae produced on-farm using organic waste reduces reliance on imported soya and fishmeal. This sustainable system converts farm and food industry residues into high-quality, regionally sourced feed for aquaculture and livestock. A pilot site in Bavaria produces one tonne of larvae monthly, with trials showing one kg of dry feed yields one kg of fish growth. Farmers save up to 30% on feed costs. The process is simple: larvae are reared in automated units using local waste, harvested after one week. Ongoing studies assess feed acceptance, growth, and product quality in trout, salmon, catfish, and bass. Production costs are €900–1,000 per tonne, far below fishmeal prices. The project supports a regional circular economy for sustainable, cost-effective protein production.
