Oxygen Consumption and Body Weight in the Marine Amphipod, 'Parathemisto guadichaudi (Guerin)'.
Abstract
Oxygen consumption was determined micro-volumetrically for specimens of Parathemisto guadichaudi (Guerin) taken in a six foot Issacs-Kidd midwater trawl at several stations in the Norwegian Sea and the North Atlantic Ocean during the summer of 1967. The average weight-specific rates as determined in this study, 411.6 cu mm/gram wet weight/hour at 15C, and 367.8 cu mm/gram wet weight/hour, at 20C, are somewhat higher than the reported average rate of 325 cu mm/gram/hour for another marine species, Pherusa fucicola at 21.5C, and somewhat less than the average of 533 cu mm/gram/hour for the brackish water species Gammarus locusta at 21.5C. Based on evidence obtained from this study, it is suspected that the lethal temperature for this species lies between 21.44C and 25C. (Author)
