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 mmgram wet weighthour at 15C, and 367.8 cu mmgram wet weighthour, at 20C, are somewhat higher than the reported average rate of 325 cu mmgramhour for another marine species, Pherusa fucicola at 21.5C, and somewhat less than the average of 533 cu mmgramhour 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
