Strict raw material criteria are used to ensure a high quality feed. All of the ingredients used in both moist and dry aquaculture feed are approved for use by the Canadian Food Inspection Agency. Much of the protein used in fish feed comes from small, bony fish - such as anchovies and mackerel - which are unsuitable for human consumption. Other sources of protein include soybean meal, corn gluten meal, canola meal and wheat gluten and poultry by-products. Essential vitamins, minerals and carotenoids - which provide salmon with vitamin A and give salmon their pink colour - are added to the diet. All feed ingredients are of natural origin and of the highest quality.
