A QTL Map for Growth and Morphometric Traits Using a Channel Catfish X Blue Catfish Interspecific Hybrid System
(2008-12-15)
Many genetic programs have been designed to enhance performance for different desired traits in ictalurid catfish. Using quantitative trait loci (QTL) analysis, specific culture traits can be identified so that the performance ...
Quantification of the potential spawning contribution from oyster (Crassostrea virginica) restoration projects: a comparative study among restoration sites and substrates in coastal Alabama
(2013-01-09)
Although numerous ecosystem services of oyster reef restoration have been documented, the contribution of larvae has not been previously quantified. In this study, we selected 5 restoration sites in coastal Alabama (Billy ...
Quantifying fish swimming performance and behavior in two diverse environments: a multifaceted approach.
(2019-07-11)
In the southeastern United States, low-head dams are common and the effects of these structures on migratory fishes are relatively unknown. Studying how migratory fish behave in habitats altered by dams such as the upstream ...
Quantitative methods for integrating instream biological monitoring data into aquatic natural resource management decision making

Freshwater aquatic resource management is fraught with challenges, as managers of multiple-use, highly diverse systems must frequently make management decisions with limitations including unclear management objectives and ...
Quantitative Valuation of Ecosystem Services Provided by Oyster Reefs in Mobile Bay, Alabama
(2018-04-13)
Oyster reef services have been acknowledged for their ecosystem services, but globally oyster reefs are at risk due to rapid anthropogenic and natural changes. Conservation decisions for these important habitats often ...
Realized Heritability and Response to Selection for Fecundity, Hatching Rate and Fry/KG for Channel Catfish Females (Ictalurus punctatus) Induced to Ovulate and Fertilized with Blue Catfish (Ictalurus furcatus) Males for the Production of Hybrid Catfish Embryos
(2008-12-15)
The objective of the this research was to determine the heritabilities and response to selection for fecundity, percent hatch and fry per kilogram body weight for channel catfish females induced to ovulate with luteinizing ...
Reconstructing the Past Salinities Experienced by a Freshwater and Marine Piscivore in the Mobile-tensaw River Delta Using Otolith Microchemistry
(2007-12-15)
In this study, we used changes in otolith microchemistry, with particular emphasis on otolith Sr:Ca, along the otolith growth axis to examine the past salinities, and thus the past environments, experienced by age-0 ...
