Characterization of PLA-PHB Based Active Packaging Film, and Its Application on Oysters

Miao, Luoqi (2017-11-20)

Biodegradable material polylactic acids (PLA) and polyhydroxybutyrate (PHB) were designed as the matrices for active food packaging applied on oysters. In this study, the performance of bioplastics was first evaluated ...

A Comparative Study of Habitat Value for the Juvenile Blue Crab (Callinectes sapidus) Provided by Off-bottom Oyster Farming in the Northern Gulf of Mexico

Stewart, Eric (2015-01-07)

In the northern Gulf of Mexico (nGOM), the quality and quantity of nursery habitat available for juvenile utilization is the most critical limiting factor affecting local populations of the blue crab, Callinectes sapidus. ...

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 ...

Comparing triploid and diploid growth and mortality in farmed oysters, Crassostrea virginica, in the northern Gulf of Mexico

Wadsworth, Pandora (2018-02-05)

The significance of the triploid advantage, in terms of growth and survival, varies across studies and environmental conditions. A meta-analysis was performed with 30 studies using chemically induced triploids and triploids ...

Development and Application of Grain Distillers Dried Yeast for Pacific White Shrimp Litopenaeus vannamei

Achupallas, Julio (2013-04-23)

In recent years there has been an increasing interest in developing low-cost feeds for the Pacific white shrimp, Litopenaeus vannamei. High prices and limited supply are the main factors that have affected primarily feed ...

EFFECT OF WAVE ACTION, BIOFOULING CONTROL, AND DENSITY ON THE PERFORMANCE OF EASTERN OYSTERS (CRASSOSTREA VIRGINICA)

Lewis, John (2021-06-21)

To better understand the impacts of wave action on oyster performance and its interaction with other farming choices, triploid oysters were deployed utilizing the adjustable longline system at an oyster farm site near Deer ...

Effects of culture methods in the Pacific Northwest on the levels of Vibrio spp. in farm-raised oysters (Crassostrea gigas)

Kelly, James (2021-05-18)

Oyster aquaculture utilizes both on-bottom and off-bottom culture techniques to harvest raw oysters for the half-shell market. In the Pacific Northwest, the farming practices for growing the Pacific oyster, Crassostrea ...

Effects of desiccation practices and ploidy on Vibrio spp. abundances of cultured oysters, Crassostrea virginica

Grodeska, Stephanie (2016-05-05)

The expansion of off-bottom aquaculture of the eastern oyster, Crassostrea virginica, to the Gulf of Mexico accompanied by high temperatures, which are correlated with Vibrio parahaemolyticus and Vibrio vulnificus, has ...

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 Oyster Gardening Programs of the U.S. Gulf and Atlantic Coasts

Waters, Phillip Jr. (2020-03-16)

We investigated oyster gardening programs along the Gulf of Mexico and Atlantic coasts (United States) for their organization, volunteer makeup and their capacity to change the perceived knowledge of participants. Further, ...

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