Animals with new house and empty stomach were used in the experiments. Animals and food were placed in oxygen-saturated water, and the remaining oxygen was measured with a polaro-graphic oxygen meter at the end of the experiment. Some animals wer aesthetized with tricaine methanesulfonate (Sandoz MS-222). Animals receiving more food consume more oxygen, but also become larger. After correction for body weight, food concentration did not influence respiration. Anesthesia reduces respiration by 33%.
