Bioeconomic Analysis of Catfish Produced in In-Pond Raceway Systems
(2021-11-30)
This dissertation describes catfish production over four-years using In-Pond Raceways Systems (IPRS). This technology consists of a floating raceway (RW) cage placed into an existing pond, which allows for more control of ...
Development of intensive indoor rearing strategies for largemouth bass (Micropterus salmoides) during critical early life history stages
(2022-07-25)
Largemouth bass (LMB), Micropterus salmoides, is arguably the most sought-after
recreational fish in the United States. Recently, there has been rising interest in LMB as a food
fish and current production techniques ...
Distribution, Relative Abundance, and Habitat Association of Tallapoosa Bass Micropterus tallapoosae in the Tallapoosa River Drainage, Alabama.
(2021-07-16)
The diversity of freshwater fishes and black bass Micropterus spp. in the United States are concentrated in the southeastern region. Dams, anthropogenic land use, fragmentation, invasive species and other factors are ...
Distribution, Relative Abundance, and Habitat Associations of Warrior Bass in the Black Warrior Watershed, Alabama
(2022-07-26)
Single season occupancy and zero inflated poisson models were used to identify relationships between Warrior Bass Micropterus warriorensis occurrence, relative abundance, and multiscale habitat factors. Warrior Bass ...
EFFECT OF WAVE ACTION, BIOFOULING CONTROL, AND DENSITY ON THE PERFORMANCE OF EASTERN OYSTERS (CRASSOSTREA VIRGINICA)
(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 ...
The Effects of Anthropogenic Traffic Noise on Auditory and Endocrine Function in the Blacktail Shiner, Cyprinella venusa
(2022-01-03)
Acoustic signals are a vital component of important behaviors such as courtship, foraging, parental care, and aggression. Acoustic communication is a modality utilized by a plethora of animals, including fishes. Recent ...
Effects of culture methods in the Pacific Northwest on the levels of Vibrio spp. in farm-raised oysters (Crassostrea gigas)
(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 Environmentally Relevant PFOS Concentrations on Unionid Bioaccumulation, Benthic-pelagic Coupling, and Gene Expression
(2021-08-03)
Per- and polyfluoroalkyl substances (PFAS) are persistent organic chemicals that have high energy carbon and fluorine bonds that make them resistant to metabolic breakdown and degradation. These substances are emerging ...
The effects of temperature and dissolved oxygen on fish respiration determined by enzymatic and organismal techniques
(2021-04-16)
One of the greatest threats to freshwater biodiversity is anthropogenic alteration to habitat. Temperature change is one of the most important anthropogenic impacts, especially for ectotherms that experience the effects ...
Epigenomic and transcriptomic alterations of channel catfish exposed to DNA methyltransferase inhibitor and estradiol
(2021-07-23)
Teleost fish exhibit a great level of diversity of sex determination. With channel catfish (Ictalurus punctatus), a lower teleost, sex determination genes have not been identified. However, the sex determination region ...
Essential amino acid balance in channel catfish Ictalurus punctatus diets
(2021-12-02)
Channel catfish are among the top cultured aquaculture species in the U.S. Protein is an important factor in catfish feeds to allow for proper health and development and accounts for 50%-60% of the total feed cost. Due to ...
Evaluating the effects of three Alabama River dams on fish movements and population connectivity using otolith microchemistry
(2022-04-20)
Dams impede fish movement and can isolate riverine populations into defined areas. The Alabama River is divided into four major sections by three lock-and-dam structures. I used otolith microchemistry to quantify movements ...
