Wheat gluten has technological and nutritional qualities that make it
a useful ingredient in diets for salmonids (Apper-Bossard et al., 2013). It
has high concentration of protein, with lysine as the first limiting amino
acid, followed by tryptophan and arginine. Due to the lenient technology
employed in “Vital wheat gluten” production, the protein digestibility
is high, and almost complete digestion of gluten protein was found in Atlantic salmon
