How Does Temperature Affect The Consumption Of Fish

Methods All the materials in this experiment were provided by the college and procedures were followed as per the lab manual. The independent variable in this experiment was temperature as it was the effects of temperature that was being measured. The dependent variable were ventilation rates and oxygen consumption as they were being measured. There were 10 fish per treatment level. There were two treatment levels, 25  C and 15 C. Ten fish tanks per treatment level were set up, the first group of fish tank were filled with spring water and kept at room temperature of 25 C, whereas, the second group of fish tank were filled with spring water, but padded with ice packs which lowered the temperature to approximately 15 C. The mass of the two goldfish, Carassius auratus, were measured separately by measuring the mass of the beaker initially and subtracting it from the beaker with the fish. Each fish was put in the jar with sufficient spring water without putting the lid. The fish activity was observed and allowed to get accustomed to its new environment for 10 mins.
Then, a wet sponge void of any air bubbles was placed half way of
The oxygen consumption for higher temperature which was 6.36 mL/g/hr, was higher than the oxygen consumption for lower temperature which was 1.45 mL/g/hr. These were also the Qo2 values at 25 C and 15  C. The standard deviation for higher temperature was 7.91 mL/g/hr, which was higher than the standard deviation for lower temperature which was 1.92 mL/g/hr. The Q10 for the oxygen consumption was 4.39. In the graph, the standard deviation for higher temperature was more stretched out than the standard deviation for lower temperature. Although, the mean was higher for higher temperature but the standard deviation for higher temperature was also higher than lower temperature. The standard deviations were higher than the average itself for both the
