Zebrafish As A Model For Post-Traumatic Stress Disorder (Ptsd), Bernadette Johnson
Honors Theses
Post-traumatic stress disorder (PTSD) is a psychological disorder with limited treatment options. Molecular mechanisms that cause PTSD remain unclear due to a lack of viable animal models. Considering the behavioral similarities between zebrafish (Danio rerio) and humans, their social nature, and functional parallels between select brain regions, we hypothesized that zebrafish can demonstrate PTSD and that antioxidant treatment will prevent PTSD induction. To test this hypothesis, adult zebrafish were exposed to a traumatic event then were tested immediately and three weeks after the event. Traumatized fish exhibited non-social behavior, spending 7000 fold less time interacting with tank mates then their …

Temporal Changes In The Larval Placopecten Magellanicus Population In A Small-Scale Fishery Closure Area In Coastal Maine, Usa, Jessica P. Batchelder
Honors Theses
The Midcoast Maine Collaborative Scallop Project was established in 2013 by fishers, scientists, and policy makers to determine if a small-scale closure area could restore the local Atlantic sea scallop (Placopecten magellanicus) population to an area in coastal Maine that previously supported high scallop densities. These stakeholders established a three by one mile closure area in the Lower Muscle Ridge Channel to assess the response of the adult and larval scallop populations. Understanding the larval dynamics in a closure area is key to evaluating the recovery potential of the population and for future population stock levels. This study …
