The Influence of the Probiotic PondToss™ on Growth Performance and Health of Channel Catfish, Ictalurus Punctatus, And Nile Tilapia, Oreochromis Niloticus
(2014-10-24)
In 2011, global aquaculture production of food fish comprising channel catfish and Nile tilapia reached 62.7 million tonnes with an estimated value of US$ 130 billion. As aquaculture technology intensifies to meet market ...
Mutagenesis of virulence genes in an epidemic strain of Aeromonas hydrophila ML09-119 for development of an attenuated vaccine strain
(2014-12-11)
The epidemic strain of Aeromonas hydrophila caused a devastating outbreak of motile Aeromonads septicemia of catfish (MAS) on the fish farms of Southeastern United States in 2009. A.hydrophila ML09-119 was reported to cause ...
Identification and analysis of genome-wide SNPs provide insight into signatures of selection and domestication in channel catfish (Ictalurus punctatus)
(2014-12-10)
Domestication and selection for important performance traits can impact the genome, which is most often reflected by reduced heterozygosity in and surrounding genes related to traits affected by selection. In this study, ...
Pattern of Invasion of a Nonindigenous Cyprinid and Potential Shifts in Native Fish Assemblage Structure
(2014-05-12)
Invasive species increasingly threaten global biodiversity with faunal homogenizations and are of specific concern in the highly diverse aquatic systems of the Southeast United States. However, patterns of invasion and ...
Assessing effects of supplemental feeding and Threadfin Shad addition to recreational fishing ponds using stable isotope analysis
(2014-05-05)
Pond enhancements are commonly used to increase fish production or enhance angling opportunities, but their effects are often not evaluated. I used stable isotope analysis to estimate the contribution of different rates ...
Genotype-Environment Interactions For Growth, Survival, Sexual Dimorphism and Seinability For Different Genetic Types of Channel Catfish (Ictalurus punctatus) ♀ X Blue Catfish (I. furcatus) ♂ Cultured In Three Environments
(2014-08-01)
For this study, eight genetic types of channel catfish (Ictarulus punctatus) female x blue catfish (I. furcatus) male hybrids were reared in three environments: a low density pond, a high density pond and an in-pond raceway ...
An Economic Comparison of Three Intensive Fish Production Systems
(2014-05-05)
A study was conducted to compare the economic costs and returns of three intensive aquaculture production systems located in Auburn and Browns, Alabama. The objective of this project was to examine the potential profitability ...
A Comparison of Ageing Methods in Red Snapper Lutjanus campechanus
(2014-04-23)
Sectioning otoliths and counting annuli is an accepted method for ageing of red snapper (Lutjanus campechanus). To reduce effort, time, and costs, whole otolith increment counts were compared to sectioned otolith increment ...
Fundulus grandis otolith microchemistry as a metric of estuarine discrimination and environmental conditions in the northern Gulf of Mexico
(2014-06-25)
The Gulf Killifish Fundulus grandis is an important component of saltmarsh ecosystems and is an ideal choice as an indicator species for environmental changes, given that it remains near the same marsh throughout its life. ...
Using sonar habitat mapping and GIS analyses to identify freshwater mussel habitat and estimate population size of a federally endangered freshwater mussel species, Amblema neislerii, in the Apalachicola River, FL
(2014-05-02)
Identification and quantification of freshwater mussel habitat in large turbid rivers is challenging. Sonar habitat mapping offers a low cost and time efficient means to identify and quantify benthic habitats over large ...
