Chemokine ccl33 is a key regulator of fish barbel development
(2017-07-22)
Barbels are integumentary sense organ that can be found in fishes, reptiles and amphibians. Barbel structures are relatively simple, consisting of central rod of cartilage, nerve trunk, artery and taste bud. The cell types ...
The Effects of the Masou Salmon Delta5-Desaturase Transgene on N-3 Fatty Acid Production in F1 Transgenic Common Carp (Cyprinus carpio) and Channel Catfish (Ictalurus punctatus)
(2017-04-21)
The objectives of this study were determine the effectiveness of the Masou salmon delta5-desaturase transgene driven by a beta-actin promoter for improving n-3 fatty acid production in F1 transgenic common carp, Cyprinus ...
Fortification of commercial catfish rations with superdoses of phytase enzymes increases hematological parameters and mineral stores in channel catfish (Ictalurus punctatus) and hybrid catfish (Ictalurus punctatus x Ictalurus furcatus)
(2017-04-17)
Phytic acid is a well-known antinutritional factor and readily binds to di and trivalent ions reducing their bioavailability and thus absorption by the animal. Phytic acid levels in catfish diets have risen along with ...
Application of genome-wide association studies in channel catfish to identify QTL associated with hypoxia tolerance
(2017-03-07)
Catfish is the dominant aquaculture species in the United States. The production of the domestic catfish industry rapidly increased in the last two decades. However, as imported catfish from Southeast Asia have kept ...
A habitat risk assessment and breeding site projection for Slackwater Darter (Etheostoma boschungi) in Limestone Creek
(2017-04-16)
Catalysts for species decline are difficult to identify and are rarely single. The use of predictive models that incorporate multiple factors have proven useful in recognizing major drivers of species declines in multiple ...
Comparisons Among Channel Catfish Ictalurus punctatus, Blue Catfish I. furcatus, Channel ♀ × Blue ♂ Hybrid Catfish and Transgenic Channel Catfish for Growth, Cold and Salinity Tolerance
(2017-04-12)
Two studies were performed related to salinity tolerance and the potential effect of climate change on genetic choices for catfish farming. The first study examined the growth rate and survival rate among channel catfish ...
Evaluation of bioelectrical impedance analysis methods for use on Channel Catfish
(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, ...
Identification of sex determination gene(s) through comparative sequence analysis of X and Y chromosomes in channel catfish
(2017-07-07)
One of the most fundamental and fascinating processes of life is the determination of
sex. Scientists have worked for hundreds of years to understand the mechanism of sex
determination in the fields ...
Effects on Water Quality of Additional Mechanical Aeration in the Waste-Treatment Cells in Split-Pond Aquaculture Systems for Hybrid Catfish Production
(2017-04-20)
Split-pond aquaculture is a new, innovative system for intensification of pond aquaculture in the southeastern USA. Split ponds have a fish cell and a waste cell, approximately 20% water surface area and 80% water surface ...
Optimizing a Standard Sampling Program to Evaluate Fish Community Structure for Non-wadeable Rivers in Alabama
(2017-08-03)
Alabama’s non-wadeable rivers support exceptionally high biodiversity of fishes but no formal sampling program has been developed to monitor the fish community in these systems. Recent developments in Alabama have caused ...
