Digestibility values were determined for diets of varying protein content fed to Arctic charr. The use of these values, in conjunction with food intake data made possible the study of the effects of various parameters on the control of food consumption. Dietary energy content may be more important than protein content in regulating consumption. The regulation of food intake may be partially mediated through factors influencing gastric emptying coupled with mechanisms monitoring dietary metabolizable energy.
