Oxygen consumption and CO 2 production of R. gigas were measured during the austral winter. O 2 uptake was lower than for low latitude species; the RQ was substantially below 0.7. High lipid content and low respiratory gas exchange in antarctic plankton indicate lipid oxidation for energy, suggesting metabolic adaptation through utilization of NADP‐dependent oxidations. Two periods of reproduction of R. gigas are evident.
