NEWS 126 FEED & ADDITIVE MAGAZINE November 2025 The Review of the State of World Marine Fishery Resources 2025, the most comprehensive global assessment of marine fish stocks to date, was released by the Food and Agriculture Organization of the United Nations (FAO). The report finds that all assessed Antarctic fisheries, including the krill fishery, are sustainably managed under robust, science-based international regulation. The report – produced with contributions from more than 650 experts across 200 institutions and over 90 countries – highlights the critical role of science-based management and international cooperation in achieving sustainable fisheries worldwide. “This confirmation from FAO reinforces what science has shown for years – that the Antarctic krill fishery is among the most strictly regulated and sustainably managed fisheries in the world,” said Matts Johansen, CEO of Aker BioMarine. “Sustainability has been a fundamental part of our company since before our first vessel entered the Southern Ocean. We built our entire operation on transparency, science, and long-term stewardship.” FAO highlights that the krill fishery in the Antarctic operates under one of the world’s most precautionary management systems. Catch limits established by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) are set at a small fraction of the estimated biomass, ensuring that the ecosystem remains healthy and resilient. Released in 2025, the FAO’s findings take on new relevance as CCAMLR members meet in Hobart, Australia in October to discuss the establishment of new Marine Protected Areas (MPAs) in the Southern Ocean.

When it comes to how it works, scientists particularly point to two synergies: Between the mineral zinc and the omega-3 fatty acids EPA and DHA, and between the lipid cholesterol and saturated fat. Saturated fat and cholesterol, which are often associated with adverse health effects in humans, are important for salmon. Over the past decades, fish oil has been gradually replaced with vegetable oil in feed, and during this time, the salmon's requirement for saturated fat has not received sufficient attention, explains Nofima scientist Nini Sissener. “Saturated fat has a greater impact on fillet quality than previously thought. Fishmeal and fish oil possess a unique composition of omega-3, saturated fats, and cholesterol. It is therefore important to assess what these changes mean for the quality of salmon raised on today’s plant-dominated feed,” says Sissener. Sissener carried out this study while employed at the Institute of Marine Research. The research revealed that frozen salmon fillets lost more liquid during thawing when sourced from fish that had received insufficient saturated fat during the growth phase. Additionally, low cholesterol level in the feed reduced the fillet’s firmness and red coloration. Read more>> Nutrient interactions drive salmon health and growth Photo: Terje Aamodt, Nofima
