A replicated, controlled study in Norway (Pratoomyot et al., 2008) found salmon, Salmo salar, fed fish oil, decontaminated fish oil and different vegetable oil diets had similar growth rates and final average body weights. In terms of n-3 highly unsaturated fatty acids, essential to humans for protecting against cardiovascular disease, soybean-based vegetable oil produced higher levels in salmon flesh compared to rapeseed oil. One of five experimental diets were fed to groups of 120 salmon for 10 weeks: 100% fish oil, 100% decontaminated fish oil and three different of vegetable/fish oil blends (using soybean or rapeseed oil). Growth rates and n-3 highly unsaturated fatty acid content were measured.
