Abstract: | The adenylate energy charge ratio (EC) of 8 species of zooplankton ranged from 0.70 to 0.89. Eucalanus subcrassus had significantly (P<0.05) lower EC when captured during a 30-min tow than during a 3-min tow, indicating stress at capture. The concentration of ATP in the 8 species ranged from 9.1 to 36.0 g/mg protein and from 0.17 to 15.7 g/mg dry weight. Excluding a low value for the ctenophore Pleurobrachia sp., the average concentration was 8.1 g ATP/mg dry weight, which is equivalent to an approximate C/ATP ratio of 50.Contribution from the Australian Institute of Marine Science, Australia, and the Institute of Marine Biology, University of Bergen, Norway |
