摘要：

Temporal variations in food consumption of three year classes of Arctic charr, Salvelinus alpinus, held under conditions of constant temperature (10-degrees-C) and continuous artificial illumination were studied by monitoring daily food intake at different times of the year. Food was supplied continuously in excess and consumption was determined using X-radiography. There were found to be seasonal differences in the amounts of food consumed, with food intake being lowest during the autumn. Attempts were made to relate these changes to patterns of sexual maturation, but results were equivocal and further study is required in order to isolate the factors responsible for variations observed.
