Feeder Guppies: A Study

Decent Essays
For our study, we will look at the behavior of feeder guppies (Poecilia reticulata) in response to a tapping noise on the glass of the aquaria. We intend to test for stress induced behavioral responses that may occur in response to the tapping noise.
Will tapping on the outside of the tank effect the position and avoidance of feeder guppies?
Because we are looking at the behavior of fish in response to tapping, we cannot use an alternative to live animals. We chose to use feeder guppies because they are a small, schooling fish that has a known set of behaviors that can be easily observed. In all, we will be using ninety guppies for the duration of this experiment. We need a large number of guppies because we will have nine tanks for repetitions

Most of these studies involve marine fish and do not look at an aquarium setting. However, a couple of studies have, including Anderson, et al. (2010), which looks at the stress responses of the lined seahorse to chronic noise exposure. Another study looked at the disruption of normal swimming behavior of zebrafishes as well as whether or not they choose a relatively quiet tank over a noisy tank (Neo et al., 2015). However, we could find no study that looked at the effects of a tapping noise on the glass of a tank on aquarium fish. Our distinction of the effects of noise produced by tapping on the glass is important because this externally generated noise could stress fish and have important implications for zoos and aquariums as well as for pet…show more content…
After this is added, we record the row number the fish is in every 15 seconds for 2 and a half minutes. Then, after this is added, we also add food to row 1. This allows us to see if they begin to associate the tapping with food or if the tapping is too scary for them to even want the food. We then observe and record every 15 second for 5 minutes.
For tank 3 (tapping all the time [device on row 1]): after the first 2 and a half minutes, we add food to row 1. We then record and observe the row number the fish is in every 15 seconds for 2 and a half minutes.
Using the row data collected, we will be finding the position index and the avoidance index of the fish. The avoidance index is how often it was in row 1 before the stimulus compared to how often it was in row 1 after the stimulus was added (more times there means it is attracted to the stimulus and less times there means it doesn’t like it or is scared of it) . The position index is the difference between the average row number after the stimulus minus the average row number before the stimulus.
