A GOLD NUGGET FOR THE SALMON FEED INDUSTRY
We are proud to announce that our relentless pursuit of research-driven solutions to unlock major opportunities for improved sustainability in the feed and food industries has once again yielded significant results. Our colleague and industrial PhD student, Ingrid Schafroth Sandbakken, has just published her second paper in the Frontiers of Marine Science journal, again unveiling the potential and industrial opportunities of hydrolyzed by-products from farmed Atlantic salmon.
These fresh residual raw materials, found right in our own backyard, are as rich in high-quality proteins and lipids as the salmon itself. They can be processed for further nutritional use within just a few hours, all with a minimal carbon footprint. In this particular study, we identified a true "gold nugget" for salmon farmers and the feed industry: a highly digestible, locally sourced protein with numerous benefits for both fish and the environment.
In the second published paper, titled "Replacing fishmeal with salmon hydrolysate reduces the expression of intestinal inflammatory markers and modulates the gut microbiota in Atlantic salmon (Salmo salar)," Ingrid and her co-authors demonstrate that salmon hydrolysate (SPHSD) is a promising and safe novel feed ingredient for Atlantic salmon, owing to its excellent amino acid profile and high digestibility.
Key findings from both studies include:
✅ Improved initial growth of Atlantic salmon
✅ Higher protein digestibility, making it easier to process
✅ No prions detected in the hydrolysate, fully approving it as a feed protein hydrolysate for the same species
✅ Reduced intestinal inflammation markers, indicating decreased gut inflammation
✅ Positive modulation of the gut microbiota

Inflammation and disease remain major challenges in the salmon industry, and scientifically proven, enhanced feed ingredients from our own resources are a significant step towards making our globally renowned salmon more resilient, healthier, and more climate-friendly.
Big congrats to Ingrid and her co-writers on a great achievement benefiting the entire salmon industry.
