A Comparison of Fish and Epibenthic Assemblages on Artificial Reefs With and Without Copper-Based Anti-Fouling Paint
(2008-09-09)
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 ...
Age determination through shape analysis and validation of otolith annular increments in red snapper, Lutjanus campechanus
(2008-09-09)
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, ...
Utilization of Distiller’s Dried Grains with Soluble in Catfish Feeds
(2009-07-16)
Feed is generally the largest expenditure in semi-intensive and intensive catfish culture operations, and protein is the most expensive component of feeds. Efforts to reduce feed costs have resulted in increased use of ...
Nest survival, nesting behavior, and bioenergetics of redbreast sunfish on the Tallapoosa River, Alabama
(2009-02-23)
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 ...
Investigations of Brackish Water Aquaculture in the Blackland Prairie Region of Western Alabama
(2009-02-23)
Three investigations were performed related to brackish water aquaculture in the
Blackland Prairie region of western Alabama. Two of these investigations were related
to pond fertilization with magnesium fertilizers ...
Habitat Use of Larval and Juvenile Cape Fear shiners (Notropis mekistocholas)
(2009-02-23)
The factors responsible for imperilment of freshwater fishes are diverse, but most
can be categorized as some form of habitat loss or alteration. Understanding effects of
various forms of habitat alteration on single ...
A QTL Map for Growth and Morphometric Traits Using a Channel Catfish X Blue Catfish Interspecific Hybrid System
(2009-02-23)
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 ...
The Roles of Acoustic and Visual Signals in the Reproductive Behavior of the Federally Threatened Pygmy Sculpin, Cottus paulus, (Cottidae)
(2009-07-02)
Animals use many modes of communication (i.e. tactile, visual, acoustic and chemical) for territory defense, resource defense, and/or courtship. These communication systems can be used singularly or combined together, such ...
Demonstration for Integration of Genetic Linkage and Physical Maps of Catfish Using BAC-Anchored Microsatellites
(2009-03-30)
Catfish is the major aquaculture species in the United States. The development of genetic linkage maps with high marker densities and the development of physical maps are important steps toward genome-enable genetic ...
General Fish Health Assessment and Age Evaluation of Impinged Fish at Steam Generating Power Plants
(2008-09-09)
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 ...
