A controlled, replicated study in Tasmania, Australia (Carter et al., 2010) found that Atlantic salmon fed soy protein diets with at least 4000 units per kg of phytase had higher average final body weight (93.49g) than those fed an un-supplemented controlled diet (82.35g). Average final body weights were similar in diets supplemented with 250 and 1,000 units per kg (84.32-89.1g). Percentage survival was not significantly different between treatments (96–100%). Groups of salmon were fed one of four experimental diets and a control diet for a 12 week period. Phytase was added at levels of 250, 500, 1,000 or 4,000 units per kg to salmon diets that had low fish meal content (4.5%) and contained 60% soy protein concentrate. Fish were bulk weighed every three weeks throughout this time.
