Supplementary material- Lipid and gene expression data and statistics from Interaction between ω 6 and ω 3 fatty acids of different chain lengths regulates Atlantic salmon hepatic gene expression and muscle fatty acid profiles
Atlantic salmon smolts (approx. 20-month old) were fed experimental diets with different combinations of omega-6:omega-3 fatty acids (FAs) (high-ω6, high-ω3, or balanced) and EPA + DHA levels (0.3, 1.0 or 1.4%) for 12 weeks. Muscle FA (% total FA) reflected dietary C 18 -polyunsaturated FA; however,...
