Abstract: The way temperature effects ventilation and oxygen consumption in goldfish (Carassius auratus) were examined during this experiment. In a closed environment the available oxygen is limited. As a result the fish metabolic rate decrease. Each fish was placed into one of two containers, that were closed after the fish placement, one with water at a temperature of approximately 20oC, which indicated warmer temperature, and the other with water at a temperature of approximately 10oC, indicating colder temperature. The number of operculum movements per minute and the levels of oxygen consumption was measured with the through the use of an oxygen probe. The Q10 and QO2 were calculated in order observe the mean change in both ventilation rate and oxygen consumption, which showed a value of 1.73. To test the significance of the calculated value a t-test was performed. I hypothesize an increase in ventilation and oxygen consumption for the goldfish in the warmer temperature water, and decreases in ventilation and oxygen consumption for the goldfish in the colder temperature water. However, our results displayed that our hypothesis were rejected. Introduction: Oxygen is essential for the exchange between CO2 and O2 and for the production of ATP. ATP is used in cells in order to be able to produce sufficient nutrient. Oxygen consumption in…show more content…
Our t-test results for ventilation rates under high and low temperature, was a significant difference of (T(10) = 4.70 p < 0.05) that indicated that ventilation rates increase or decreased under low or high temperature respectively. The null hypothesis stated that the temperature will have no effect on the goldfish ventilation rate or oxygen consumption rate. Suggesting that goldfish depends on the temperature from the environment surrounding them. Therefore, rejecting the null
