Title: Quantifying schooling behavior: Studying the effect of temperature and school size on the collective response of fish to a threat
Abstract: A number of factors affect schooling in fish which can have larger implications on the ecosystem. In this talk, I will describe the experiments we conducted to study the effect of water temperature and group size on how fish respond to a loom stimulus. I will describe the methods we used to quantify their behavior and preliminary results. Identifying the effect of water temperature on their ability to respond as a group to a threat can give us insight into how most fish, which are ectothermic, are vulnerable to fluctuations in external temperature. This can have an effect on predator prey interactions if an endothermic predator can take advantage of fish in cold waters or if the fish can compensate by changing their behavior.
