 note = {In order to determine the respiration rates of planktonic organisms, an electrode respirometer was
devised. The animal used in this experiment was the mixohaline rotifer, Brachionus plicatilis. The
dissolved oxygen meter and penrecorder employed here were the YSI-57 and YEW-3046,
respectively.
A 200 ml glass bottle was used as a respiration chamber. The bottle was horizontally set on a
shaker which was rotated with a semi-circular motion, like an automobile wiper. The oxygen
electrode and flow-through pipes were fixed on the neck of the chamber with a rubber stopper.
Filtered water was poured into the respiratory chamber by a peristaltic pump, at a rate of 10 ml ･ min^<-1>
for 30 minutes; and stagnant status was maintained for another 80 minutes. This procedure was
repeated every 110 minutes.
Apparent rate of oxygen consumption was observed by the difference of maximum and minimum
amounts of oxygen content during the stagnant status. Blank test, without the animals in chamber,
was also conducted. Actual rate of the oxygen consumption by the animals was then re-calculated
by the balance of those two results. This apparatus could be applied for determination of respiration
rate in planktonic organisms, fish eggs, larvae, and BOD in culture water.},
