Shark Diversity And Relative Abundance At Myrtle Beach, Sc Fishing Piers, Lynsey E. Isner

Honors Theses

Sharks are frequently observed at fishing piers (Barwick et al. 2004; Martin et al. 2019). These piers offer structural habitats for shark prey items, such as smaller fish and invertebrates, which can attract sharks to piers (Barwick et al. 2004; Heupel 2005). Additionally, fishers often clean their catch and discard entrails at the pier, which also may attract sharks (Martin et al. 2019). Moreover, other factors could play a role in attracting sharks to piers. These include water quality parameters, like salinity and temperature, and the physical characteristics of the pier (Ulrich et al. 2007; Castro 1996; Heupel 2005).

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 …

Automated Aquaponics Design Report, Carson Miller

Honors Theses

Aquaponic systems offer a solution to environmentally conscious, fiscally responsible individuals who wish to produce food products without the use of pesticides, genetic modification, or non-renewable resources. Further, the proliferation of inexpensive microprocessors and high quality sensors offers an opportunity for dynamic monitoring and error correcting within the aquaponic system. These aquaponic and electronic systems will be combined in this project to create an electronically monitored aquaponic ecosystem.

The Role Of Underutilized Fish In New England's Seafood System, Taylor Witkin

Honors Theses

The global fisheries crisis has led to an increasing recognition for the need to relieve pressure on overfished, popular food fish stocks. Opportunities exist to shift consumer demand toward more sustainable choices, including fish that may be locally abundant. Attempts have been made to market underused fish (sometimes termed “trash fish”) that represent more sustainable alternatives; however, it is unclear whether consumers will choose to purchase these more sustainable options, particularly if underused fish are also unfamiliar. Chapter 1 reviews existing research and current issues surrounding sustainable seafood and the recent shift toward local, abundant, undervalued species in New England’s …

Adaptive Mechanisms For Aquatic Existence In Freshwater Turtles, Oscar Gloor

Honors Theses

Naturalists have often marveled at the ability of some air-breathing vertebrates to remain underwater for long periods of time (that is, "long" from man's reckoning). Seals, penguins, porpoises, and whales are all noted fro their ability to use oxygen stored in various ways to permit them to "stay under" for many minutes.

The return of vertebrates, which evolved on land, to an aquatic existence has been a much discussed subject from an evolutionary standpoint. That there are many advantages to life underwater is easily seen simply by the fact that, according to fossil records, terrestrial life arose from the sea. …

Physiological Adaptations Of Aquatic Turtles, Oscar Gloor

Honors Theses

Naturalists have long noted the remarkable ability of aquatic turtles to remain submerged for long periods of time. Only recently, though, has much serious attention been given to discovering the mechanisms which enable turtles to survive for so long in the relatively hypoxic aquatic environment.
