CHANGE IN RATE OF RESPIRATORY METABOLISM IN A TELEOST FISH INDUCED BY ACCLIMATIZATION TO HIGH AND LOW TEMPERATURE

¹ From the Scripps Institution of Oceanography, University of California, La Jolla, California

The results of two experiments are presented showing the effect on the oxygen metabolism produced by acclimatizing fishes to high and low temperatures. It is concluded from an analysis of these data that fishes acclimatized to a high temperature have a much lower rate of metabolism at a common intermediate temperature than do fishes acclimatized to a low temperature, and that the magnitude of this difference is a function of the difference between the acclimatization temperatures.
