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 ...
Technical and Educational Aspects of Stream Biomonitoring Protocols for Teachers and Citizen Monitors in Alabama
(2008-09-09)
Accuracy of the Alabama Water Watch (AWW) Stream Biomonitoring Protocol for citizen monitors was assessed through a desktop study comparing simulated AWW stream quality assessments to known professional bioassessments. ...
Effects of Spatial and Temporal Variability of Shoal Habitat on Stream Fish Assemblages in Chattahoochee Tributaries, Alabama
(2008-09-09)
Abiotic factors associated with habitat quality may have profound effects on fish assemblage structure. Variability in physical habitat parameters as well as temporal fluctuation in characteristics such as water depth and ...
Physical-Chemical and Biological Characterization of Small Streams Following Intensive Forest Management Practices in the Coastal Plain of Alabama
(2008-09-09)
This study measured changes in five first-order streams (S 1 through S 5) following management techniques including clearcut logging and chemical (S 2 and S 3) and mechanical site preparation (S 4 and S 5). The herbicides ...
Distribution, abundance, and population characteristics of shoal bass in tributaries of the Chattahoochee River, Alabama
(2008-09-09)
The shoal bass Micropterus cataractae is the most recently described black bass species and in east-central Alabama, this fish only occurs in streams that flow into the Chattahoochee River. Recently, shoal bass were listed ...
An Evaluation of Natural and Artificial Dietary Lipid Sources on Egg Quality and Fry Production in Channel Catfish (male) X Blue Catfish (female) Hybridization
(2008-09-09)
Hybrid catfish (channel catfish Ictalurus punctatus? x blue catfish I. furcatus?) display many characteristics that are favorable to aquaculture production such as increased growth, resistance to disease, higher dress out ...
Replacement of Poultry By-Product Meal in Production Diets for the Pacific White Shrimp (Litopenaeus vannamei)
(2008-09-09)
In recent years there has been increasing interest in the replacement of animal proteins with plant proteins in commercial feeds for the Pacific white shrimp, Litopenaeus vannamei. Primary reasons for this interest are to ...
