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 ...
Estuaries as habitat for a freshwater species: Ecology of largemouth bass (Micropterus salmoides) along a salinity gradient
(2009-02-23)
Similar to the freshwater systems largemouth bass inhabit, the largemouth bass is a popular recreational sportfish in estuarine environments, like the Mobile-Tensaw Delta. However, catch rates of large (= 2.3 kg) largemouth ...
The Effects of a Modified Flow Regime on Fish Assemblages in a Third-Order Piedmont Stream in Lee County, Auburn, Alabama
(2009-02-23)
I examined the effects of a modified flow regime on fish assemblage condition over a 2-year period at two sites in Chewacla Creek, a third-order Piedmont stream (Lee County, AL). My goal was to assess the biotic condition ...
Effects of Anoxia on Histology, Bacteriology, Condition Index, Glycogen Levels, and Fecundity in the Eastern Oyster, Crassostrea virginica
(2008-09-09)
The eastern oyster, Crassostrea virginica, is well known for its commercial and ecological roles in Mobile Bay, AL. During summer months oysters may be exposed to hypoxic and occasionally anoxic conditions which in turn ...
