Individual Differences In Zebrafish (Danio Rerio) Behavior: Implications For Personality, Christina Nicole Toms

Master's Theses

Individual differences (IDs) in zebrafish (Danio rerio) behavior were examined across time and contexts in order to investigate personality traits. Zebrafish (N = 30) were exposed to six behavioral tasks that were collectively expected to capture (a) aggression, (b) boldness/shyness, and (c) fear. The tasks included a small open field, mirror exposure, emergence, large open field, novel object, and predator exposure tasks. IDs in behavior were found to be consistent across time for a majority of behaviors and consistent across contexts for all but two behaviors. Convergent and discriminate evidence was examined for the three constructs. There was …
