A07 Fish Respiration & Q10

In this lesson, the Q10 principle is demonstrated by measuring the metabolic rate of goldfish at two different temperatures: 22° C (acclimation temperature) and 32° C (acute exposure temperature). The fish are placed in a sealed metabolic chamber with a known amount of oxygen that will decline as the fish consumes it over time (~30 min). Temperature of the water in the chamber is controlled using a water bath. Changes in oxygen levels are recorded using the BIOPAC MP30 System for later data analysis.

Experimental Objectives

  1. Demonstrate the Q10 principle by measuring the metabolic rate of goldfish at two different temperatures: 22° C (acclimation temperature) and 32° C (acute exposure temperature).
    • Monitor the decline in a known amount of oxygen as the fish consumes it over time (~30 min.) in a sealed chamber of water at each temperature, using the BIOPAC Dissolved Oxygen Probe Transducer (SS69L).
    • Record the change using the BIOPAC MP30 System.
    • Measure the change in the partial pressure of oxygen (PO2) and use the solubility coefficient to calculate the change in content.
  2. Calculate the oxygen consumption of the fish at the two different temperatures.
  3. Calculate the Q10 of fish acclimated to 22° C.
