Farmed Salmon Omega-3 Levels Decline Amidst Feed Changes
CB Signal9A US Department of Agriculture-led study found that farmed salmon have significantly lower levels of Omega-3 fatty acids compared to previous years, likely due to changes in feed. The aquaculture industry is reducing its use of fish oil and fish meal, opting instead for soy and rapeseed as feed ingredients, a shift driven by declining marine fish stocks.
Why it mattersThis finding suggests a potential reduction in the nutritional benefits of farmed salmon for consumers and highlights the growing pressure on terrestrial ecosystems and climate as aquaculture shifts its feed sources.
