Age determination through shape analysis and validation of otolith annular increments in red snapper, Lutjanus campechanus

Beyer, Sabrina (2008-05-15)

The periodicity and timing of otolith growth rings in red snapper was examined through a mark-and-recapture study and with known-age, hatchery-reared fish. In 2005 through 2008, red snapper (n = 265) were caught hook-and-line, ...

Age, growth, home range, movement, and habitat selection of redeye bass (Micropterus coosae) from the middle Tallapoosa River tributaries (Alabama, USA).

Knight, John, II (2011-01-13)

Redeye bass Micropterus coosae is a common, but underutilized sport fish resource in Alabama. This species is the most attractive of all the black basses, and has a reputation as a formidable catch on light tackle. Redeye ...

A Comparison of Fish and Epibenthic Assemblages on Artificial Reefs With and Without Copper-Based Anti-Fouling Paint

Miller, Dianna (2008-05-15)

Artificial reefs attract fish, but whether or not actual production occurs remains unclear. To examine this question, fish and epibenthic assemblages were compared between reefs with and without copper-based anti-fouling ...

Effects of Environmentally Relevant PFOS Concentrations on Unionid Bioaccumulation, Benthic-pelagic Coupling, and Gene Expression

Strozier, Amanda (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 ...

Effects of hydrologic variation on dynamics of channel catfish and flathead catfish populations in regulated and unregulated rivers in the southeast USA

Sakaris, Peter (2006-12-15)

Altered flow regimes resulting from dam construction can have negative impacts on growth and recruitment of fishes in regulated river systems. The effects of hydrologic variation on channel catfish Ictalurus punctatus and ...

Effects of striped bass stocking on largemouth bass and spotted bass in Lewis Smith Lake, Alabama

Shepherd, Michael (2008-05-15)

Striped bass Morone saxatilis have been introduced into over 100 USA reservoirs over the last several decades to provide additional sport fishing opportunities and to control abundant shad, Dorosoma spp. populations. ...

Effects of Water Flow, Distance, and Male Density on the Fertilization Success of Freshwater Mussels

Mosley, Tyler (2012-07-23)

Previous studies suggest that fertilization of female freshwater mussels is dependent on the distance between mates and may fail at low mussel density. This has critical implications for conservation of sparse populations. ...

The Environmental Outcomes of Collaborative Natural Resource Institutions

Adams, David (2016-03-25)

Across the United States there are collaborative partnerships and networks co-laboring to manage environmental and natural resources including our watersheds. There are over 2,000 of these watersheds in which at least ...

Evaluation of bioelectrical impedance analysis methods for use on Channel Catfish

Sharp, Julie (2017-12-11)

Assessment of body composition is an accurate measure of condition. This study evaluates bioelectrical impedance analysis (BIA) methods for Channel Catfish Ictalurus punctatus. BIA shows promise as a quick, inexpensive, ...

An Evaluation of the Catfish Fishery in Wilson Reservoir, Alabama

Holley, Michael (2006-12-15)

On Lake Wilson, Alabama, a popular recreational and commercial catfish fishery exists and this study was initiated to assess population metrics and estimate exploitation. Currently, creel or length limits are not used to ...

General Fish Health Assessment and Age Evaluation of Impinged Fish at Steam Generating Power Plants

Knight, Amelia (2008-12-15)

Fish health assessments were made between impinged and reference fish collected at and in the vicinity of Steam Plant Gorgas (Black Warrior River, Walker County, Alabama) during three seasons: spring/summer, fall, and ...

A Hook and Line Assessment and Angler Survey of the Tallapoosa River Fishery (Alabama, USA)

Gerken, Clark (2015-12-10)

Angler satisfaction is one of many fundamental objectives in the adaptive evaluation of flow prescriptions below R. L. Harris Dam on the Tallapoosa River in Alabama. We have collected fishery specific information to inform ...

Nest survival, nesting behavior, and bioenergetics of redbreast sunfish on the Tallapoosa River, Alabama

Martin, Benjamin (2008-12-15)

Adaptive management has been implemented in the Tallapoosa River, Alabama; one objective of the process is to determine how discharge and temperature affect redbreast sunfish reproductive success. Nesting male redbreast ...

Oligotrophication Effects Following Diversion of Waste Effluent from an Embayment of Lake Martin, Alabama

Dickey, Richard (2006-12-15)

I examined the effects of nutrient diversion on water quality, phytoplankton, and macroinvertebrate and fish community structures over a 10-year period in Lake Martin, Alabama. In 2001, a pipeline began diverting treated ...

Quantitative methods for integrating instream biological monitoring data into aquatic natural resource management decision making

Kennedy, Kathryn D. Mickett (2015-03-20)

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 ...
