Labelling fish diets with 15N ‐Leucine for monitoring feed consumption and bio‐distribution in Atlantic salmon
Abstract Feeding represents 50–70% of the cost of production in salmon farming, higher than any other animal farm. The improvement of this percentage is challenging as the food is thrown into the fish tank, there is no quantification of the amount of food that is consumed by the fish. In consequence...
