Salmon fry just 3 weeks after hatching are dependent on a plum-shaped external food sack as they grow old enough to feed. After they mature, they are introduced to saltwater and put into pens in the fjord to go from 200 grams to 5 kilograms and gain approximately 1 kg of body weight for every 1 kg of dry food. Adult food consists of fish meal, fish oil, soybeans, and red dye to give the final flesh a pink color.
