June 17, 2026 — The research builds on existing literature on marine ingredient use in aquaculture, with a particular focus on fish conversion efficiency and nutrient retention. It compares different methodologies used to assess
“fish as feed” dependency and efficiency, supported by case studies across species and feeding strategies.
The findings underline the importance of optimizing marine resource use within global food systems.
Aquatic food production operates along a continuum that spans both fisheries and aquaculture, rather than a strict divide between the two. Maximizing the availability of essential nutrients for human populations remains a critical priority.
The FIFO Performance Tool is already experiencing strong industry uptake, with over 100 users to date.
This includes leading feed companies, with one publishing the outputs in their 2025 sustainability impact report, as well as emerging ingredient producers, NGOs, academics and others – enabling all users to model and quantify their impact on FIFO metrics.
“A unified “fish-as-feed” sustainability framework moves us from fragmented, unverified claims to credible impact-through consistent measurement, clear comparability, and shared transparency. It provides the foundation for a common language the industry can scale across other sustainability priorities” said Malcorps.
