The Q-teach AQUA Package is designed for teaching the principles of respirometry in small aquatic organisms like fish, molluscs and other aquatic invertebrates. Measurements of changes in dissolved oxygen (DO) with optical DO probe are the basis of this package. Aquatic animals are placed in a polycarbonate chamber filled with oxygenated water. The chamber has a stir bar in its base and sits on top of a magnetic stirrer to ensure good mixing of the water. The DO probe measure the rate of change in DO as animal respires. When DO levels drop the user can turn on a gas pump, that is connected to the gas input of the chamber and oxygenate the water. The package includes a temperature probe that is also placed in the water during measurements. The software provided with the package collects the data and provides analysis functions for calculating metabolic activity of the animals.
