Evaluation of a Trivalent Vaccine for Aeromonas hydrophila, Flavobacterium columnare, and Edwardsiella ictaluri Using In-pond Raceway Systems in West Alabama
(2019-07-15)
A trivalent vaccine, for virulent Aeromonas hydrophila, Flavobacterium columnare, and Edwardsiella ictaluri, was tested using in-pond raceway systems (IPRS) located in three active commercial catfish ponds. The goal of ...
Acoustic telemetry of shark movements and residency near artificial habitats in the northern Gulf of Mexico
(2019-04-24)
In the present study, acoustic telemetry was used to monitor the movements and residency of seven Sandbar Sharks Carcharhinus plumbeus, five Atlantic Sharpnose Sharks Rhizoprionodon terraenovae, four Bull Sharks Carcharhinus ...
Studies on the digestive gland microbiome of freshwater mussels
(2019-04-16)
Freshwater mussels are among the most imperiled aquatic invertebrates in North America. In the United States, Alabama has the highest diversity of freshwater mussels with 178 species. To address the conservation needs of ...
The Efficiency of Modified Canola Oil as a Replacement of Menhaden Fish Oil in Practical Diet for Pacific White Shrimp, Litopenaeus vannamei
(2019-04-17)
Lipids are an essential component of the diet serving as source of energy and components of cell structures. Marine species require a certain level of specific fatty acids in their diet as they have limited ability to ...
Comparing Angler Effort and Catch Rate Estimates Across Creel Survey Methods at Three Alabama Reservoirs
(2019-12-19)
I compared different creel survey methods at three Alabama reservoirs (Harris, Jordan, and Mitchell) to identify approaches that could improve precision and reduce costs. I was particularly interested in whether boat ...
Analysis of gamete interactions, maternal, and paternal effects for improving hybrid catfish aquaculture
(2019-11-18)
Hatchery techniques and technologies have evolved to make the large-scale production of channel catfish (Ictalurus punctatus) × blue catfish (I. furcatus) hybrids viable and profitable, but there are still reproductive ...
Gene Editing and Hormone Therapy to Control Reproduction in Channel Catfish, Ictalurus punctatus
(2019-04-23)
Channel catfish (Ictalurus punctatus) and their hybrids account for more than 60% of aquaculture production in the US. The catfish industry is being severely challenged during recent years as a result of higher operating ...
Comparing Responses of Triploid and Diploid Eastern Oysters, Crassostrea virginica, to Common Farm Stressors
(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 ...
A metabolic approach to assessing interactions between climate change, agrochemicals, and freshwater mussel reproduction
(2019-04-16)
Unionid mussels are a fundamental part of stream ecology yet are one of the most threatened aquatic organisms due in part to habitat loss, stream fragmentation, and deterioration. The increasingly relevant effects of climate ...
Association analysis of intraspecific ESC resistance QTL and identification of landscape of promoters in catfish on the genome-wide level
(2019-07-02)
Catfish is the most important aquaculture species, accounting for over 50% of aquaculture production in the US. However, disease problems threaten the survival of the catfish industry. Bacterial diseases are a major issue ...
