Tg. Bailey et al., EFFECT OF DECOMPRESSION ON MESOPELAGIC GELATINOUS ZOOPLANKTON - A COMPARISON OF IN-SITU AND SHIPBOARD MEASUREMENTS OF METABOLISM, Marine ecology. Progress series, 113(1-2), 1994, pp. 13-27
Weight- and carbon-specific rates of respiration for 4 mesopelagic gel
atinous zooplankton (2 ctenophores, 1 trachymedusa and 1 pelagic holot
hurian) measured in situ were 2 to 5 times higher than those from ship
board incubations. These results support the theory that removal of de
ep-living gelatinous species from natural environments can adversely a
ffect their metabolism. The disparity between in situ and shipboard tr
eatments is most simply explained by an interaction between pressure a
nd activity, i.e. a loss of motor activity due to decompression occurr
ed among animals used in shipboard experiments.
