A full factorial design to investigate interactions of variable essential amino acids, trace minerals and vitamins on Atlantic salmon smoltification and post transfer performance

•High dietary Vit E and C was related to higher salmon mortalities following transfer•Balanced dietary trace minerals and essential amino acids important in salmon diets•Improved FCR at higher organic trace mineral dietary supplementation•Improved amino acid ADC by respective increased dietary supplementation•Increased mucus component related gene expression at high nutrient supplementation
