What is in the English BSF operating manual, who it is for, and the thesis behind it: smaller plants close to waste, and unit economics before scale.
A new Waste Management meta-analysis puts ash beside protein and fat in BSFL process control, with useful thresholds for substrate pilots.
Innovafeed's warning: fishmeal spikes are not a BSF strategy. Scarcity opens the trial. 2% attractant or 5–10% health-window use has to hold after prices fall.
The next El Niño is an aquafeed resilience test. BSF only helps if it is already qualified: specified, trialled and contractable before the shock.
Peru's 2026 anchoveta ban and fishmeal near US$3,000/t are a feed-security shock. BSF is an alternative, not a tonne-for-tonne fishmeal replacement.
Aquaculture feed security is input sovereignty: 2026 fish oil at a decade low, insect meal up to 20% in salmon and trout, and EU substrate rules still tight.
The EU opened insect PAP for aqua, poultry and pig feed. Catering waste, manure and meat-and-bone meal stay banned. Substrate access is still the bottleneck.
Riesenbach et al. tested BSF full-fat meal, defatted meal, oil and chitin in rainbow trout. 4% oil and 1% chitin helped in low-soy diets; high-soy did not.
Ma et al. tested 2.5% and 5% whole-body or defatted BSFL in high-soy rainbow trout diets. The result is one of the clearest arguments for selling BSF as a complementary functional ingredient rather than only as fishmeal replacement.
Onomu and Okuthe's 2024 review: position BSF as a functional aquafeed additive for health, resilience and feed efficiency, not crude protein.
Global fishmeal output fell 28% in Q1 2026 (IFFO). That tightness strengthens BSF in aquafeed as a planned ingredient, not a crude fishmeal substitute.
Aquaculture Magazine's review of functional feed additives is a useful prompt for the insect sector: BSFL meal may be more valuable as a targeted gut, immune and diet-stability tool than as a blunt fishmeal replacement story.
Minerals in BSFL can be steered via substrate. A 2026 paper found brewery spent grains outperformed conventional feed for zinc and manganese accumulation.
A new Food Microbiology paper reports that Bacillus cereus persisted through Hermetia illucens rearing, with larvae and frass requiring post-rearing treatment even when authorized substrates were used.
