Analysis of gamete interactions, maternal, and paternal effects for improving hybrid catfish aquaculture

Myers, Jaelen (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 ...

Combining Ability of Channel Catfish (Ictalurus punctatus) Females and Blue Catfish (Ictalurus furcatus) Males for Tolerance of Low Oxygen Using a Factorial Design

Taylor, Zachary (2019-04-18)

The channel catfish, Ictalurus punctatus × blue catfish, I. furcatus hybrid shows increased performance over the channel catfish for many traits, including tolerance of low dissolved oxygen. Performance of hybrid offspring ...

Development of intensive indoor rearing strategies for largemouth bass (Micropterus salmoides) during critical early life history stages

Aguilar, Gavin (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 ...

Fundamental aspects of sperm biology for ecologically and economically important bivalve species in Alabama: Cellular signaling, morphology, and density quantification

Nichols, Zoe (2020-05-21)

The Eastern oyster, Crassostrea virginica, and freshwater mussels, Ligumia subrostrata and Lampsilis straminea, are significant keystone species in the Eastern United States. These bivalves both provide invaluable environmental ...

Hearing Capabilities of the Atlantic Mudskipper (Periopthalmus barbarus) Across Mutiple Media.

Todd, Davis (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)

Hess, Hana (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 Salinity and Seasonality on Reproductive Physiology in Diploid and Tetraploid Eastern Oyster (Crassostrea virginica)

Tackett, Victoria (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 ...

An Investigation of Fin Erosion in Channel Catfish

Paulson, Matthew (2020-07-14)

An ongoing case of fin erosion affecting Ictalurid catfishes at an aquaculture research facility in the southeastern United States was investigated. Circumstantial evidence collected at this facility has provided several ...

Optimization of stem cell extraction from blue catfish (Ictalurus furcatus) to produce alloxenogenic catfish: Effects of body size, sex steroids, and seasonality

Hettiarachchi, Darshika (2020-04-20)

Xenogenesis has been identified as an innovative technology for hybrid catfish (♀ channel catfish, Ictalurus punctatus × ♂ blue catfish, I.furcatus) embryo production. Currently, donor cells are collected from randomly ...

Quantifying Male Reproductive Performance of Blue Catfish (Ictalurus furcatus) to Improve Hatchery Production of Hybrid Catfish

Montague, Helen (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 ...

Targeted Gene Insertion and the Effect of Random Insertion of the Masou Salmon Delta5-Desaturase Transgene on n-3 Fatty Acid Production and Culture Traits of Channel Catfish (Ictalurus punctatus)

Huang, Yingqi (2018-11-07)

Channel catfish (Ictalurus punctatus) is one of the most abundant catfish species in North America. The objectives of this study were to determine the effectiveness of the Masou salmon delta5-desaturase transgene driven ...
