The effect of laboratory conditions on the extrapolation of experimental measurements to the ecology of marine zooplankton VI. Changes in physiological activities and biochemical components of Acetes sibogae australis and Acartia australis after capture

Physiological activities comprising respiration, electron transport system (ETS) activity and excretion of ammonia and phosphate, and the biochemical components protein, RNA, ATP and adenylate energy charge (EC) were measured.
