  1. Use supplements

    A controlled, replicated study in Tasmania, Australia (Sajjadi et al., 2004) found similar levels of weight gain and feed intake of Atlantic salmon that were fed diets with or without phytase and phosphate supplementation. Weight gain over the experiment was between 192.3 and 220.3 g per fish. Total feed intake was between 3.88 and 4.39 kg per salmon. Four diets were fed to groups of Atlantic salmon for 12 weeks; one diet with no phytase or inorganic phosphorus supplementation, one diet with phytase, one diet with supplemental inorganic phosphorus and one with both phytase and supplemental inorganic phosphorus. The diets were canola meal protein based with reduced fishmeal and were not commercial diets. Twenty fish per tank were fed one of the experimental diets (3 tanks for each diet treatment) and anaesthetised, counted and bulk-weighed every 3 weeks.
