Abstract
During a period of temperature increase from 8.8 to 11.2 degrees C fro m May to August, maturing one-sea-winter Atlantic salmon showed decrea sing appetite from early June, to little or no food intake by early Ju ly. In contrast, non-maturing siblings increased food intake steadily from early June throughout the period. The number of anorexic maturing fish increased throughout the summer, suggesting that anorexia is dep endent on an internal cue. (C) 1997 Elsevier Science B.V.
