Danish company Aerbio says its microbial protein Proton, made by fermenting CO2 and hydrogen, outperformed high-quality fishmeal in a salmon trial. The company reports a feed conversion ratio of 1.01–1.10 over 56 days versus 1.50 in the control group, and says Proton has about 95% protein digestibility in salmon.
A credible fishmeal substitute would add supply for aquafeed protein and could pressure fishmeal demand over time. The claims are company-reported and the product is positioned as a complement rather than a replacement, so the near-term price impact is limited.
