Use an alternative oil source: plant-based Sustainable Aquaculture

In 2005, a randomised study in Scotland (Schlechtriem et al., 2007) found that salmon, Salmo salar, fed diets containing vegetable oil had lower proportions of n-3 highly unsaturated fatty acids than diets containing fish oil. Flesh from salmon fed the fish oil diets contained 26.0% of n-3 highly unsaturated fatty acids compared to 17.7% in vegetable oil fed fish. HUFA is essential for protecting humans from cardiovascular disease. Over 12 weeks, groups of 30 salmon were fed diets containing either 100% fish oil or vegetable oil (comprised of rapeseed, linseed and palm oils at a 2:2:1 ratio). Flesh was analysed for n-3 highly unsaturated fatty acid content.
