Researchers at the University of Stirling’s Institute of Aquaculture, in collaboration with the universities of Lancaster, Aberdeen and Cambridge, have developed a groundbreaking method to enhance nutrient retention in farmed fish feed

Currently, farmed fish such as salmon are inefficient at converting omega-3 and other nutrients.

The new approach, called the nutrient fish-in fish-out (nFIFO) ratio, builds on the existing fish-in fish-out metric but factors in nutrient retention alongside the biomass of wild fish used for feed.
