Population genomics and geospatial tools to inform management and research priorities for non-marine molluscs
(2022-03-07)
Non-marine molluscs comprise a large portion of biodiversity on Earth. However, they are among the most understudied and imperiled groups globally. As such, there is a pressing need to fill knowledge gaps regarding fundamental ...
Quantifying Male Reproductive Performance of Blue Catfish (Ictalurus furcatus) to Improve Hatchery Production of Hybrid Catfish
(2023-04-20)
Catfish farming constitutes about 60% of total U.S. aquaculture production, where the channel catfish, Ictalurus punctatus female × blue catfish, I. furcatus male hybrid accounts for >50% of the harvest. Current hatchery ...
Sorptive Removal of Per- and Polyfluoroalkyl Substances (PFAS) from Water by Biochars
(2023-05-01)
This thesis aims to employ biochar (a carbonaceous material) as a cost-effective sorbent to remove per- and polyfluoroalkyl substance (PFAS) from water by two case studies. Study 1 seeks to identify which biochars perform ...
Spawning and Early Ecology of Riverine Shoal Bass and Largemouth Bass
(2024-04-29)
Understanding fish movements and early life-history requirements is important for managing populations because they reflect changing resource needs across the life cycle. Riverine black basses (genus Micropterus) hold ...
Taxonomy and Systematics of Fish Blood Flukes (Digenea: Schistosomatoidea) using Morphology, Phylogenetics, and Life History
(2023-11-06)
The monophyletic fish blood flukes (Platyhelminthes: Digenea: Schistosomatoidea Stiles, 1898) comprise ~186 species of 46 genera infecting freshwater, marine, and estuarine fishes. They are occasional pathogens of cultured ...
Taxonomy, Systematics, and Histopathology of Myxozoan (Cnidaria: Myxozoa) Parasites of Fishes
(2023-11-08)
Myxozoans, a parasitic lineage of cnidarians, comprise over 2500 species infecting primarily freshwater, marine, and estuarine fishes. This includes several demonstrable pathogens to cultured fishes including: Myxobolus ...
Taxonomy, systematics, and life cycle of digeneans (Platyhelminthes: Trematoda) infecting freshwater fishes
(2023-11-08)
This dissertation is structured in 7 chapters. In the dissertation, I described 4 new digenean
species and redescribed 3 species belonging to 7 genera of 5 families, erected 1 new genus,
resurrected and emended the ...
TESTING MATERNAL CONTRIBUTIONS IN TRIPLOID EASTERN OYSTERS (CRASSOSTREA VIRGINICA): A FIELD EVALUATION IN COASTAL ALABAMA
(2021-05-14)
With the establishment of off-bottom aquaculture in the northern Gulf of Mexico, triploid oysters have become the mainstay of production due to their well-documented advantages; however, there have been observations in ...
Texture Analyses of Catfish: A Genetics Approach
(2021-04-16)
Channel catfish (Ictalurus punctatus) and hybrid catfish (channel catfish ♀ × blue catfish (Icatlurus furcatus) ♂) aquaculture dominates the US aquaculture industry. These catfish genetic types have been heavily researched ...
Understanding how cyanobacterial communities respond to different dissolved nitrogen forms
(2021-04-12)
This thesis explored the ways in which cyanobacterial communities respond to three common nitrogen forms (i.e., nitrate, ammonium, and urea) via two field experiments. Chapter I describes a field experiment that demonstrated ...
USE OF HIGH PROTEIN DISTILLER'S DRIED GRAIN AS AN ALTERNATIVE INGREDIENT IN PRACTICAL DIETS OF DIFFERENT SPECIES (Ictalurus punctatus, Litopenaeus vannamei and Oreochromis niloticus)
(2023-11-15)
Increasing worldwide competition and shifts in demand, technological advancements, and innovative research findings are triggering the ingredient manufacturing industry to include modified processing technologies and novel ...
Use of Metabolically Modified Canola Oil as a Replacement for Fish Oil in Practical Diets of Pacific White Shrimp Litopeneaus vannamei
(2021-08-04)
The rapid growth of the aquaculture sector can be stifled by the inadequate supply of fish oil, leading the sector to search for alternative oil sources. The efficacy of metabolically modified canola oil (MCO) has not been ...
Using Fisheries Techniques to Estimate the Age and Growth of Hybrid Catfish (Ictalurus punctatus ♀ X I. furcatus ♂) in West Alabama Commercial Ponds
(2023-07-27)
In west Alabama, catfish producers routinely face the challenge of fish that exceed market size (aka “Big Fish”) in their commercial ponds. These fish are skilled at evading seine nets during harvest and can increase in ...
Using Multiple Approaches to Evaluate the Effects of Flow Regulation on Fishes in the Tallapoosa River, Alabama.
(2021-12-01)
Dams alter many aspects of riverine environments and generally have broad effects both upstream and downstream. Despite the variety of potential benefits of dams to humans (recreation, flood control, navigation, etc.), ...
Using physiological approaches to quantify potential effects of anthropogenic alterations to river systems on fishes
(2024-04-13)
In this dissertation, I used an ecophysiological approach to study the effects of dams on fishes via studies on swimming performance, metabolic rate, and thermal tolerance. The first study focused on 4 fish species (Channel ...
