Reassessment of the Red Drum Stock in Mississippi Coastal Waters: The Role of Ages 3-5 Year-Class Fish
<p>Red Drum, <em>Sciaenops ocellatus</em>, are highly sought after by sport fishermen in Mississippi coastal waters. In 2016, Mississippi anglers made over 180,000 fishing trips targeting Red Drum, making it the second most targeted marine species. The current Fishery Management Plan of the Gulf of …

Life-History Characteristics and Fishery Dynamics of Red Drum (<i>Sciaenops ocellatus</i>), in the North-Central Gulf of Mexico
<p>Red Drum (<em>Sciaenops ocellatus</em>) are highly targeted recreationally in the Gulf of Mexico, and support a small commercial fishery in Mississippi. Despite their popularity, the stock is assessed using data limited approaches that necessitate accurate life history information. I estimated …

Red drum (Sciaenops ocellatus) Habitat Use in an Urban System; Behavior of Reintroduced Fish in Bayou St. John, New Orleans
… efforts. I tested the ability of reintroduced red drum (Sciaenops ocellatus) to survive in this system and assessed their habitat use and behavior. I tracked 29 red drum fitted with external acoustic radio transmitters to determine if they could survive the degraded habitats and determine their …

Regulation of elements of the thyroid hormone and corticosteroid systems by stress, hormone treatment, and atrazine during ontogeny of red drum (Sciaenops ocellatus)
… hormone (TH) and corticosteroid (CS) systems in red drum (Sciaenops ocellatus). Basal cortisol production was first detected 3 days post-hatch (DPH) and a cortisol stress response was present from 6 DPH forward. Changes in steroidogenic enzyme mRNA (CYP11B and CYP21) levels did not correlate with …

Fish Assemblage Dynamics and Red Drum Habitat Selection in Bayou St. John and Associated Urban Waterways located within the City of New Orleans, Louisiana
… Louisiana. I studied habitat selection of red drum in BSJ, and fish assemblage change in BSJ and CPLL over 40 years. Temperature was found to be the best predictor of red drum habitat selection in Bayou St. John, while salinity and change in depth also were found to be good predictors for …

Spatial Variation in Basal Resources and Trophic Position of Selected Fishes of the North-Central Gulf of Mexico
… exhibited varying degrees of habitat usage, with Red Drum being the most diverse, while Gafftopsail Catfish and Atlantic Sharpnose shark had more habitat specificity. This study presented evidence that freshwater inputs influenced the isotope values of reef fish species. d<sup>15</sup>N values of …

Movement Ecology and Trophic Dynamics in the northern Gulf of Mexico: Implications for Fisheries Management
… and forage fishes, to high-trophic-level predators (e.g. Yellowfin Tuna). This thesis contributes to the region’s ecological knowledge, with the primary aim of enhancing management efforts and providing direct management advice to two important fisheries. In Chapter 1, we develop a …

Biology, Captive Propagation, and Feasibility of Pearl Culture in the Pink Heelsplitter (Potamilus Alatus) (Say, 1817) (Bivalvia: Unionidae)
… (r = - 0.72); lowest monthly survival occurred in summer, resulting in a significant difference among the three locations with a similar trend after 1 yr. The glycogen reserves of mussels in captivity for 1 yr differed by pond location, higher in mussels at the shallow end than those in …
