An Open-System Respirometer for Measuring Steady-State Oxygen Uptake by Aquatic Animals Applied to the Scallops Pecten maximus L.

Djoko Suprapto

An open-system respirometer for measuring steady-state oxygen uptake rate of aquatic animals is
described. The principle of the measurement was to calculate the difference between the oxygen
concentrations of the water entering the respiratory chambers with that out from the respiratory
chambers. This difference indicated the oxygen consumed by the animals for their respiration. The
measuring system was tested to calculate the oxygen consumption related to dry body weight of scallop
Pecten maximus L. collected from different populations. This correlation was expressed by allometric
equation as: Y = aXb. The equation was then discussed with the finding of several authors.
