Microalgae and organic minerals enhance lipid retention efficiency and fillet quality in Atlantic salmon (Salmo salar L.)

Pure spray dried DHA rich microalgae biomass (Schizochytrium sp.) was used to replace fish oil as a source of long chain n-3 polyunsaturated fatty acids (n-3 LC-PUFA) in medium (150 g kg− 1; MF) and low fish (100 g kg− 1; LF) meal diets for Atlantic salmon post smolt supplemented with either inorganic or organic minerals (OM: Zn, Cu, Mn, Fe and Se). The diets were balanced for total saturated fatty acids (SFA), sum DHA + EPA and n-3/n-6 ratio...
