Evolution of Signal Divergence and Behavior in Cyprinella galactura, the whitetail shiner
(2008-09-09)
Acoustic signaling in anurans, insects, birds, and mammals has played an important role as an interspecific isolating mechanism and is also believed to be a mechanism of sexual selection in intraspecific mate choice. A ...
A Comparative Study of the Immunological Properties of Extracellular Products Between Virulent and Less Virulent Edwardsiella tarda
(2008-09-09)
The immunological properties of the extracellular products (ECP) of the Edwardsiella tarda parent FL6-60 and mutant RET-04 isolates were investigated in Nile tilapia Oreochromis niloticus. Non-purified ECP derived from ...
Effects of hydrologic variation on dynamics of channel catfish and flathead catfish populations in regulated and unregulated rivers in the southeast USA
(2008-09-09)
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 ...
Oligotrophication Effects Following Diversion of Waste Effluent from an Embayment of Lake Martin, Alabama
(2008-09-09)
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 ...
An Evaluation of the Catfish Fishery in Wilson Reservoir, Alabama
(2008-09-09)
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 ...
Mercury Bioaccumulation Patterns in Two Estuarine Sportfish Populations
(2009-02-23)
Mercury (Hg) is a harmful bioaccumulative heavy metal to which humans are
exposed primarily through fish consumption. Several consumption advisories for
mercury have been issued for fishes along the US Atlantic and ...
An Evaluation of Triploid Flathead Catfish
(2009-02-23)
The overall objective of this research was to develop an effective protocol to produce triploid flathead catfish, Pylodictis olivaris. To accomplish this goal, data was gathered depicting characteristics of flathead catfish ...
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
(2009-02-23)
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 ...
Movement, dispersal, and home ranges of tournament displaced largemouth and spotted bass in Lake Martin, Alabama
(2008-09-09)
Anglers fishing in black bass tournaments often displace fish great distances from their site of capture and the effects of tournament displacement on movement and behavior of fish after release have been variable. ...
The Economic Significance of Aquatic Biotechnology in the Production of Channel Catfish (Ictalurus punctatus) Female X Blue Catfish (I. furcatus) Male Hybrid (CB Hybrid) Embryos
(2008-09-09)
The current cost of commercially producing CB hybrid catfish fry is 325% higher than that of channel catfish due to the CB hybrid’s high production costs and low hatch rates. However, CB hybrid catfish fingerlings cost ...
