Improving the (off)-bottom line: assessing the costs and benefits of different culture techniques on an Alabama commercial oyster farm
(2020-05-13)
Off-bottom oyster aquaculture is an expanding industry in the Gulf of Mexico region, however numerous challenges threaten the sustainability of regional farms. To offset the negative effects of these challenges, farmers ...
Effects of Tagging and Translocation on Paddlefish in the Alabama River
(2020-07-30)
Dams directly impede fish movement. Different passage structures have been incorporated into the design of dams in attempt to restore connectivity, however, passage is limited to particular fish species. Lock-and-dam ...
Juvenile Density, Fishing Mortality, and Habitat use of Red Snapper, Lutjanus campechanus, on Artificial and Natural Reefs in the Northern Gulf of Mexico.
(2020-11-18)
The Red Snapper, Lutjanus campechanus, fishery in the Gulf of Mexico has been intensively regulated as managers attempt to rebuild the fishery. This has led to a need for improved data collection, and a better understanding ...
Cryopreservation of blue catfish stem cells for conserving genetic resources and xenogeneic transplantation
(2020-05-13)
In the United States, channel catfish (Ictalurus punctatus) ♀ × blue catfish (I. furcatus) ♂ hybrids now account for 70% of total freshwater aquaculture production. Hybrid fry production can be improved by cryopreserving ...
The swimming performance of Freshwater Drum (Aplodinotus grunniens) below Claiborne Lock and Dam and in various temperature and dissolved oxygen treatments
(2020-07-24)
Alterations to temperature and dissolved oxygen regimes in the tailwaters below dams can cause harmful stress to fish. Although Freshwater Drum Aplodinotus grunniens are widespread in rivers across North America, this ...
Effect of Host Age and PKH26 Dye Concentration on Stem Cell Viability, Colonization Rate, and Offspring Performance for Production of Xenogenic Catfish
(2020-05-15)
Xenogenesis has been identified as an innovative technology for hybrid catfish (♀ channel catfish, Ictalurus punctatus × ♂ blue catfish, I. furcatus) embryo production. Currently, blue catfish donor stem cells are collected ...
Exploration of the Anti-biofilm Effects of Fish Antimicrobial Peptides Against Common Aquaculture Pathogens
(2020-07-17)
Aquaculture’s rapid growth and commercialization has been accompanied by increased spread of fish-related diseases that threaten aquaculture’s production capabilities. Diseases caused by Gram-negative bacteria such as, ...
Estimation of Red Snapper Abundance on Oil and Gas Platforms in the northern Gulf of Mexico based on Mark Recapture Methods
(2019-11-19)
Estimating abundance of sport and commercial reef fish species remains difficult due to cryptic habitat use patterns. One such species is Red Snapper, Lutjanus campechanus, which is perhaps the most important fish species ...
Test of the effects of geography, gear type, and culture techniques on Vibrio risks associated with farm-raised oysters
(2020-11-16)
During the off-bottom aquaculture growing process for the eastern oyster, Crassostrea virginica, farmers routinely remove the oysters for tumbling and desiccation. These routine handling practices improve oyster quality ...
