Goldfish Respiration Rate

Decent Essays

Using cold water to decrease the temperature was effective in slowing down a goldfish’s rate of respiration. These findings are in agreement with previous research (Perey 2014). The null hypothesis, that decreasing temperature of the water environment would not affect the goldfish’s respiration rate, was rejected. As the temperature of the water environment decreased by two degrees every 2 minutes, to the beaker the goldfish was in, the number of breathing rate of the goldfish decreased at least 10 respirations each time. The biggest difference that was found between the initial temperature of 22 degrees and the decreased temperature of 20 degrees. The multiple trials that were ran constantly decreased, further supporting the results. The results
