Abstract
The rates of oxygen consumption of Euphausia pacifica Hansen, Thysanoëssa spinifera Holmes, and Sergestes similis Hansen at 1 atm were compared with the rates at 16–50 atm. Differences were not significant, indicating little effect of pressure on respiratory rate. Apparently temperature has more influence than pressure on the respiration of these species during their diel vertical migrations.
