Bio-economic Factors Affecting Feasibility of Floating In-pond Raceway Systems: A Stella Modeling Approach

Regan, Rachel (2011-05-19)

Floating in-pond raceway (FIPR) systems have the potential to efficiently compete with conventional ponds in their ability to produce large quantities of fish profitably. However, little is known about the biological and ...

Comparing Responses of Triploid and Diploid Eastern Oysters, Crassostrea virginica, to Common Farm Stressors

Bodenstein, Sarah (2019-04-18)

Commercial off-bottom aquaculture of the Eastern oyster, Crassostrea virginica, is challenged by repeated spring and summer mortality events that disproportionally affect triploid oysters. Many farmers believe common farm ...

Dispersal of Pederson cleaner shrimp among host sea anemones: Impacts of shrimp body size and social group interactions

Winn, Carly (2019-11-18)

Pederson shrimp Ancylomenes pedersoni are the most common cleaners of reef fishes in the Caribbean Sea. They also are obligate associates of sea anemones, especially corkscrew anemones Bartholomea annulata; together these ...

Ecology of crayfishes in the Ozark Highlands ecoregion of Oklahoma

Ramey, Jordan (2023-04-27)

Crayfishes aid in the transfer of nutrients through aquatic ecosystems and are prey to many aquatic and terrestrial species. Although their importance in ecosystem dynamics is generally well recognized, information ...

Economic Assessment of the Production of Native Shrimp Species as an Alternative to Supply Demand of the Live Bait Industry in the Southeast USA

Paz, Patricio E. (2010-08-04)

The recreational fishing industry of the Gulf of Mexico is a multi million dollar industry that positively impacts coastal communities through the creation of new jobs and revenue. Native shrimp are a popular live bait ...

Effects of Acute Thermal Stress on Texas Hornshell Mussel (Popenaias popeii)

Radich, Jessica (2023-11-28) ETD File Embargoed

Extreme weather conditions are placing increasing stress on aquatic ectotherms in the southern U.S. We investigated effects of thermal stress on the federally endangered Texas Hornshell (Popenaias popeii), the last freshwater ...

Effects of Thermal Stress on Unionid Glochidia and Rising Salinity on Adult Unionid Mussels

Fluharty, Ryan (2019-07-15)

Unionid mussels are considered keystone species however, they are the most imperiled group of organisms in North America. Implications from changing thermal and salinity regimes are of particular interest due to potential ...

Effects of Traveling Screen Operation on Impingement and the Survivability and Latent Health of Impinged Catfish at Barry Steam Generation Plant

Shaw, William (2010-08-04)

Two studies were conducted concurrently at cooling water intake structures at a coal fired power plant on the lower Mobile River basin. The first study observed the effects of varying operation times of traveling screen ...

Effects of Water Flow, Distance, and Male Density on the Fertilization Success of Freshwater Mussels

Mosley, Tyler (2012-07-23)

Previous studies suggest that fertilization of female freshwater mussels is dependent on the distance between mates and may fail at low mussel density. This has critical implications for conservation of sparse populations. ...

Establishing Energetic Cost of Acute Exposure to Select Anthropogenic-Caused Environmental Conditions in the North Gulf of Mexico Derived Eastern Oyster (Crassostrea virginica)

Boyd, Kayla (2024-04-16)

Oyster aquaculture is an important industry in the Gulf of Mexico and has seen a significant increase in interest over the last 20 years. Because oyster farming takes place in ambient waters, farmed oysters are subjected ...

Evaluating the Effect of Larval Period Duration upon the Subsequent Performance of Cultured Eastern Oysters, Crassostrea Virginica

Bisker, Kelsey A. (2020-07-10)

With the increase in oyster aquaculture in the United States, it is important to understand the potential effects of larval experiences on the field performance of Eastern oysters (Crassostrea virginica) to maximize hatchery ...

Evaluating various management strategies of biofloc systems and understanding the physiological basis behind the thermal tolerance of Pacific white shrimp, Litopenaeus vannamei in low salinity waters

Hussain, Aya S. (2023-04-28)

Biofloc technology (BFT), in its various types, has been known to be a realistic solution for efficiently managing water quality with low or no water exchange, enhancing shrimp growth performance and establishing an efficient ...

Evaluation of a flow-through depuration system to eliminate the human pathogen Vibrio vulnificus from the eastern oyster (Crassostrea virginica)

Lewis, Matthew (2010-08-03)

Evaluation of a flow-through depuration system to eliminate the human pathogen Vibrio vulnificus was carried out through altering 3 different parameters: salinity, temperature, and flow rate. Oysters were supplied by Auburn ...

Evaluation of a Mechanical Grader for the Improvement of the Aquaculture Production of the Eastern Oyster, Crassostrea virginica, in the Northern Gulf of Mexico

Coddington Ring, Courtney (2012-01-09)

In order to develop culture regiments that increase oyster product quality and profitability, commercially available oyster aquaculture growout gear, a rotary style mechanical grader (“tumbler”) and three handling treatments ...
