Impact of n−3 fatty acid chain length and n−3/n−6 ratio in Atlantic salmon (Salmo salar) diets

A feeding trial was carried out to test the impact of n − 3 fatty acid chain length and n − 3/n − 6 ratio in diets for Atlantic salmon, according to a 2 × 4 factorial design. Two dietary fat sources: fish oil (FO), rich in long chain EPA and DHA and linseed oil (LO) rich in linolenic acid were replaced by increasing levels of sunflower oil (SO) rich in linoleic acid: 0, 25, 50 and 75%. Thus eight experimental diets were produced containing...
