Oxygen Consumption in an Antarctic Hemoglobin-Free Fish, Pagetopsis Macropterus, and in Three Species of Notothenia
The rate of oxygen consumption was determined in an Antarctic hemoglobin-free fish, Pagetopsis macropterus, and in three species of Notothenia, all of which have hemoglobin. In P. macropterus, the consumption at 0 degrees C ranged from 0.012 to 0.022 ml O2/g per hr, one-half to one-quarter of that i...
