Geographic Variation in Trace Element Profiles of Shrimp and Viability of Elemental Profiling as a Traceability Tool
(2021-07-07)
The increased concern about the environmental consequences of shrimp culture in importing markets has led to a greater emphasis on sustainability of the products. Traceability is an important component of making claims ...
Growth performance, survival, blood chemistry, and immune gene expression of channel catfish (Ictalurus punctatus) fed probiotic-supplemented diets
(2023-04-27)
The channel catfish (Ictalurus punctatus) farming industry is the largest and one of the oldest aquaculture industries in the United States. Despite being an established industry, production issues stemming from disease ...
Hearing Capabilities of the Atlantic Mudskipper (Periopthalmus barbarus) Across Mutiple Media.
(2021-04-27)
An animal’s sensory detection mechanisms are often shaped by the environment in which that animals lies. Amphibious fishes provide a rare opportunity to study how hearing has adapted to match the extremely unique lifestyle ...
Identification of Molecular Biomarkers for Male Reproductive Success in Blue Catfish (Ictalurus furcatus)
(2022-04-27)
The overall objective of this project was to understand the underlying physiological and
molecular processes that are associated with sperm production and function. The primary
objective was to identify RNA biomarkers ...
Impacts of flue gas desulfurization (FGD) gypsum in hypereutrophic waters
(2023-07-27)
Flue gas desulfurization (FGD) gypsum is a by-product of carbon-based energy sources that has been beneficially used as a component of concrete mixes and wallboard as well as in land-based agriculture as a soil amendment. ...
Impacts of Salinity and Seasonality on Reproductive Physiology in Diploid and Tetraploid Eastern Oyster (Crassostrea virginica)
(2023-12-06)
The demand for high-value aquaculture products, like Eastern oyster (Crassostrea virginica), necessitates efficient commercial hatchery strategies. Triploid oysters, derived from mating diploid females with tetraploid ...
Impacts of Seasonal Thermal Stress on Energetics of Popenaias popeii (Texas hornshell)
(2023-11-27)
Texas hornshell (Popenaias popeii) is a federally endangered mussel occurring in Texas, New Mexico, and Mexico. We examined temperature effects on energetic costs of feeding, and on scope for growth: the net energy balance ...
Improving farm pond aquaculture water quality using zooplankton and long-term monitoring
(2021-07-12)
Eutrophication and degradation of water quality place a strain on freshwater resources and call for best management strategies. In freshwater farm pond aquaculture, water quality and health of fish are important players. ...
Improving Plant-based Diets for Florida Pompano, Trachinotus carolinus.
(2021-06-21)
Florida pompano aquaculture is a growing enterprise in the United States and production is increasing. Success of Florida pompano production is dependent on the supply of cost-effective diets that promote optimal growth ...
Integration of antimicrobial peptide genes via CRISPR/Cas9 for disease resistance enhancement and reversible sterility in catfish
(2023-08-01)
The CRISPR/Cas9 platform holds promise for modifying fish traits of interest as a precise and versatile tool for genome manipulation. To reduce introgression of transgenes and control reproduction, catfish were studied for ...
Investigation of growth and immune responses in channel catfish (Ictalurus punctatus) following feeding of dietary immunostimulants
(2023-07-26)
The commercial farming of channel catfish (Ictalurus punctatus) in the United States often faces economic losses due to infectious diseases caused by opportunistic pathogens. Using natural immunostimulants has positively ...
