Abstract
The changes in the feed of farmed Atlantic salmon (Salmo salar) towards a more plant-based diet affect the nutritional value of the fillets. By compiling the contents of a range of nutrients in 1108 samples of Norwegian farmed Atlantic salmon collected between 2005 and 2020, we found that the median contents of eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA) have decreased by > 60%. However, farmed Atlantic salmon remains a considerable source of EPA and DHA, with one and two portions being sufficient to meet the weekly adequate intake of EPA and DHA for adults (175 g) and two-year-olds (80 g), respectively. Farmed Atlantic salmon also remains a considerable source of protein, selenium, vitamin B12, and vitamin D3. Together, we demonstrate that farmed Atlantic salmon can contribute substantially to the nutrient intake of the consumers. These data are important for the Norwegian food composition table and future risk–benefit assessments on fatty fish consumption.
Highlights
According to the recent biannual “The State of World Fisheries and Aquaculture” report by the Food and Agriculture Organization of the United Nations (FAO) (FAO, 2020), global aquaculture production has been the fastest growing food production sector for the past few decades, currently providing more than half of the global supply of fish available for human consumption
We show that the contents of marine omega-3 fatty acids, eicosa pentaenoic acid (EPA) and docosahexaenoic acid (DHA), have significantly decreased over the past 15 years in Norwegian farmed Atlantic salmon
This study demonstrates that farmed Atlantic salmon is able to provide con sumers with high amounts of EPA and DHA, with one portion for adults and two portions for two-year-old children being sufficient to meet the weekly recommended intake
Summary
According to the recent biannual “The State of World Fisheries and Aquaculture” report by the Food and Agriculture Organization of the United Nations (FAO) (FAO, 2020), global aquaculture production has been the fastest growing food production sector for the past few decades, currently providing more than half of the global supply of fish available for human consumption. In order to keep pace with the continu ously growing global population and the increase in demand for fish and seafood products, a greater proportion of fish are being farmed. Atlantic salmon (Salmo salar), one of the main fish species in European aqua culture, represent an increasingly popular species among consumers worldwide (FAO, 2020). It is estimated that 14 million meals of Norwegian farmed Atlantic salmon are consumed every single day across the world (Norges sjømatråd [Norwegian Seafood Council], 2020)
