Abstract
The effects of temperature, temperature flution, and fish size on the growth of juvenile steelhead trout (Salmo gairdneri) were studied in experiments which lasted 10-25 days. Groups of fish were fed at ration levels varying from near-starvation to repletion. Decelerating, curvilinear relationships between rates of food consumption and growth were defined in most of the experiments. At ration levels near maintenance, temperatures raised 3-6C above the seasonal ambient temperatures decreased the growth of the trout. As feeding rate increased, the detrimental effect of temperature on growth was ameliorated. (Modified author abstract)
