The Effect Of Dietary Thiaminase On Cardiac Function And Morphology In Lake Trout (Salvelinus Namaycush), Peter Baker Jun 2023

The Effect Of Dietary Thiaminase On Cardiac Function And Morphology In Lake Trout (Salvelinus Namaycush), Peter Baker

Electronic Thesis and Dissertation Repository

Thiamine deficiency from the consumption of invasive, high-thiaminase prey fishes is considered to be a major barrier for lake trout restoration in the Great Lakes. In fishes, an understudied aspect of thiamine deficiency is its effect on cardiac function. I examined the effects of dietary thiaminase on cardiac function and morphology in lake trout, specifically as they relate to thermal tolerance. Two hatchery strains of lake trout (Seneca and Slate) were raised on a control or thiaminase diet for nine months. The thiaminase diet was associated with significant ventricle enlargement, impaired cardiac function, and reduced thermal tolerance; these effects were …


The Influence Of Range Shifts And Wind Energy On The Atlantic Surfclam (Spisula Solidissima) And Ocean Quahog (Arctica Islandica) Fisheries On The U.S. Outer Continental Shelf, Stephanie Stromp Mar 2023

The Influence Of Range Shifts And Wind Energy On The Atlantic Surfclam (Spisula Solidissima) And Ocean Quahog (Arctica Islandica) Fisheries On The U.S. Outer Continental Shelf, Stephanie Stromp

Master's Theses

The Atlantic surfclam, Spisula solidissima, is a biomass dominant bivalve of the Northwestern Atlantic. The surfclam’s historic range extended from Cape Hatteras to Georges Bank, but recent decades of warming bottom water temperatures have caused the surfclam to shift its range to cooler waters north and offshore within the range of the ocean quahog, Arctica islandica. An ecotone now exists over much of the offshore range of the surfclam in which surfclams and ocean quahogs co-occur. Regulations prohibit fishers from landing both species in the same catch, limiting fishing to locations where the target species can be sorted …


The Effects Of Warming Rate On The Thermal Tolerance Of A Southern Population Of Striped Bass (Morone Saxatilis), James Barrett Jan 2023

The Effects Of Warming Rate On The Thermal Tolerance Of A Southern Population Of Striped Bass (Morone Saxatilis), James Barrett

Honors College Theses

Climate change and global warming is an ever-growing concern for our environment and the survivability of the animals which inhabit it. With water temperatures expected to rise 2-3℃ in the next century, many aquatic organisms may be limited in their habitats based on their thermal tolerance (Lleras 2019). Southern populations of striped bass (Morone saxatilis) in the Southeastern United States could be some of the hardest hit by the effects of climate change due to their unusual life history as compared to the more northern populations of striped bass. These southern striped bass do not engage in coastal …
