This experiment was designed to determine whether dissolved oxygen concentrations would influence the ventilation rate of goldfish, Carassius auratus. Ventilation rate can be determined by counting opercular movements. Opercular movements of the same five goldfish were counted at three different levels of dissolved oxygen to determine whether there were differences in ventilation rates. Average ventilation rates were established for each of the three levels of dissolved oxygen and compared statistically. There were significant differences in the ventilation rates averages at each of the three levels. Carassius auratus will exhibit changes in ventilation rates when dissolved oxygen levels change.
