Characterization of an Attenuated Aeromonas hydrophila Vaccine and Molecular Mechanisms of Channel Catfish Immunity against Aeromonas hydrophila infection
(2012-07-17)
An attenuated Aeromonas hydrophila AL09-71 N+R vaccine strain was compared to its virulent parent strain A. hydrophila AL09-71. The attenuated AL09-71 N+R strain was developed through selection of resistance to both ...
Characterization of Innate Immune Genes of Catfish: CXC Chemokines and Toll-Like Receptors
(2006-05-15)
Innate immunity is known as the first line of defense against pathogenic invasions. Fish, as lower vertebrates, are believed to maintain their healthy status mostly by relying on their innate immunity. Of the many types ...
Characterization of the gut and skin microbiomes of wild-caught fishes from Lake Guntersville, Alabama
(2016-07-29)
In recent years, a paradigm shift has occurred in the area of organismal health. Where Koch and Hill’s fundamental postulates equating to “one microbe—one disease” were once regarded as the rule, research has now shifted ...
Characterization, Polymorphism Assessment, and Database Construction for Microsatellites from Bac End Sequences of Catfish: A Resource for Integration of Linkage and Physical Maps
(2007-05-15)
To apply genome-based technologies for genetic improvements using markerassisted
selection, genome research involving genetic linkage mapping and physical
mapping is required, and integration of genetic and linkage maps ...
Chemical composition and pollution potential of fish and shrimp feeds
(2015-12-04)
The objectives of this research were to assess the resources use for producing aquaculture feeds and to determine the waste loads of nutrients to the culture system (system loads), along with the solution to reduce nutrient ...
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 ...
Combining Ability of Channel Catfish (Ictalurus punctatus) Females and Blue Catfish (Ictalurus furcatus) Males for Tolerance of Low Oxygen
(2017-04-21)
Catfish are the backbone of the aquaculture industry in the United States accounting for the majority of finfish production. The primary species cultured was channel catfish (Ictalurus punctatus), but that has changed as ...
Combining Ability of Channel Catfish (Ictalurus punctatus) Females and Blue Catfish (Ictalurus furcatus) Males for Tolerance of Low Oxygen Using a Factorial Design
(2019-04-18)
The channel catfish, Ictalurus punctatus × blue catfish, I. furcatus hybrid shows increased performance over the channel catfish for many traits, including tolerance of low dissolved oxygen. Performance of hybrid offspring ...
Combining Ability of Channel Catfish, Ictalurus punctatus, Females and Blue Catfish, I. furcatus, Males for Early Growth, Growth Variation, Disease Resistance, and Carcass Yield of their Progeny
(2017-12-06)
The hybrid between channel catfish (I. punctatus) females and blue catfish (I. furcatus) males is considered the best catfish genotype for commercial catfish farming due to their faster growth rate, better survival rate, ...
Comparative analysis of repetitive elements in fish genomes
(2018-03-15)
Repetitive elements make up significant proportions of genomes. However, their roles in evolution remain largely unknown. To provide insights into the roles of repetitive elements in fish genomes, this dissertation work ...
Comparative genome analysis of related catfish species
(2014-12-12)
Catfish belong to the order Siluriformes. They are one of the largest orders of teleost fish, with over 5,000 living species, accounting for approximately 15% of teleost fish species, or 7.8% of all vertebrates. Catfish ...
Comparative Genomic Analysis of Catfish Linkage Group 27 with Teleost Species Genomes
(2012-07-20)
Comparative genomics is a powerful tool to transfer genomic information from model species to related non-model species. Channel catfish (Ictalurus punctatus) is the primary aquaculture species in the United States. Its ...
A Comparative Investigation of Streptococcus Agalactiae Isolates from Fish and Cattle
(2007-05-15)
Streptococcus agalactiae is the causative bacterium of streptococcosis and causes severe economic losses in wild and cultured fish and cattle, worldwide. In fish, infection can result in septicemia with hemorrhages on the ...
A Comparative Study of Habitat Value for the Juvenile Blue Crab (Callinectes sapidus) Provided by Off-bottom Oyster Farming in the Northern Gulf of Mexico
(2015-01-07)
In the northern Gulf of Mexico (nGOM), the quality and quantity of nursery habitat available for juvenile utilization is the most critical limiting factor affecting local populations of the blue crab, Callinectes sapidus. ...
A Comparative Study of the Immunological Properties of Extracellular Products Between Virulent and Less Virulent Edwardsiella tarda
(2006-12-15)
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 ...
Comparative transcriptome analysis of catfish swimbladder reveals expression signatures in chamber formation and their response to low oxygen stress
(2018-07-18)
The swimbladder is an internal gas-filled organ in teleosts. Its major function is to regulate buoyancy. Swimbladder exhibits great variations in size, shape, number of compartments or chambers among teleosts. However, the ...
Comparative transcriptome analysis of genes expressed in the skin of channel catfish, common carp and pleco
(2015-12-10)
Channel catfish (Ictalurus punctatus), as a member of Siluriformes, has scaleless skin. However, it is hardy and resistant to many types of stresses including low oxygen, high density, handling, and infections from various ...
