The project involves expertise of feeding behaviour and self-selection by fish diet, with recent development of a geometrical frame work that provides a unique opportunity for combining these in a major new research initiative. The framework can then be used for testing new diets for farmed fish. The present project aim to test the "nutritional wisdom" in Arctic charr by challenging the fish with different diets. By experimentally testing the self-selection of the combination of different macronutrients or amount of consumed unbalance diet the fish's choice will be geometrically "framed". The answer will tell us: (1) If the charr can compose a diet that reach a nutritional target by selecting from several unbalanced diets; (2) How do they balance unbalanced diets (do get fat or slim)?; (3) How does the response of feed selection relates to the performance (growth, feed conversion factor, flesh quality etc.) of the fish. The experiments are done on individual fish where individual performance is considered and the individual competitive ability is expected to have an effect of energy need and learning ability. The set-up and experimental protocol are based on our knowledge and experience of the charrs' feeding behaviour with special emphasis of individual characteristics.
