New research suggests farmed salmon may have declined in nutritional value compared to past decades, likely due to shifts in the fish's diet. The dietary changes are also having significant downstream impacts on the environment and climate.
Background
Farmed salmon has been a major source of omega-3 fatty acids and protein globally, but changes in feed formulations—shifting from fish oil to plant-based alternatives—have raised concerns about nutritional quality.
