The aim of the extended essay is to investigate the memory of fishes, especially a special kind, Poecilia reticulate. So it is an extended essay about fish behavior and ability to memorize. Additionally, this experiment investigates the relation between the obstacles and the time for Poecilia reticulate to reach the source of food. My research question for this extended essay was: ‘Is Poecilia reticulate memory powerful enough to reuse acquired knowledge when the distance between obstacles increase through the way to source of food?’ My hypothesis for the essay is: ‘Poecilia reticulate will be able to swim faster as they adapt the environment, although the distances between obstacles increase, so they have ability to learn and memorize what they learnt for finding their food.’ In order to answer the research question I have designed my own method. In this experiment, I have used two obstacles with wholes, one of them is in the top, and one of them is in the bottom of the plates. The path was designed and the distance between the obstacles increased in every 5 days. There are also varieties in every species. So, I have used 5 Poecilia reticulate to obtain more precise data. In addition, a video camera is placed to obtain most accurate and precise data. So, I was able to watch step by step, which Poecilia reticulate swim across the obstacles. At the end of the experiment, these data have compared to each other. The experiment was successful to end up a conclusion. Results show that as the distance between obstacles increase, the time for Poecilia reticulate to reach their food also increases. Moreover, according to ANOVA test there was a significant mean difference between the increasing distances between obstacles. In this extended essay, I have used fishes, and it was important to keep up their life standards. It was also important to design an environment, which they can live in good conditions. I have done many researches about this in the beginning of the experiment. And in the end, all Poecilia reticulate was able to survive and still they are healthy.
