Immune and gustatory roles of the channel catfish skin as revealed by comparative transcriptomic analyses

Gao, Sen (2016-08-09)

Fish scales are physical barriers protecting them from various external stresses, in particular, from pathogen infections. However, vast majority of catfishes are evolutionarily scaleless. How scaleless fish respond to ...

Optimization of stem cell extraction from blue catfish (Ictalurus furcatus) to produce alloxenogenic catfish: Effects of body size, sex steroids, and seasonality

Hettiarachchi, Darshika (2020-04-20)

Xenogenesis has been identified as an innovative technology for hybrid catfish (♀ channel catfish, Ictalurus punctatus × ♂ blue catfish, I.furcatus) embryo production. Currently, donor cells are collected from randomly ...

Osteocrin: identification, expression, and CRISPR/Cas9 analysis in scale development in teleost

Prabowo, Wendy (2017-07-27)

The completion of channel catfish genome sequencing provides a possibility of performing comparative genome studies. The comparative genome study between scaleless channel catfish and armor-scaled (bony dermal plate) ...

A QTL Map for Growth and Morphometric Traits Using a Channel Catfish X Blue Catfish Interspecific Hybrid System

Hutson, Alison (2008-12-15)

Many genetic programs have been designed to enhance performance for different desired traits in ictalurid catfish. Using quantitative trait loci (QTL) analysis, specific culture traits can be identified so that the performance ...

Quantifying Male Reproductive Performance of Blue Catfish (Ictalurus furcatus) to Improve Hatchery Production of Hybrid Catfish

Montague, Helen (2023-04-20)

Catfish farming constitutes about 60% of total U.S. aquaculture production, where the channel catfish, Ictalurus punctatus female × blue catfish, I. furcatus male hybrid accounts for >50% of the harvest. Current hatchery ...

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

Gima, Megan (2008-12-15)

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 ...

Repressible Transgenic Sterilization in Channel Catfish, Ictalurus punctatus, by Knockdown of Primordial Germ Cell Genes

Li, Hanbo (2016-08-05)

Genetic engineering has great potential for development of fish with higher growth rate, better disease resistance and increased nutritional value. However, genetically modified animals could pose ecological risk to the ...

Reproductive Confinement of Common Carp, Cyprinus carpio, and Channel Catfish, Ictalurus punctatus, via Transgenic Sterilization

Su, Baofeng (2012-12-05)

Transgenic animals had shown great potential for increasing growth rate, ability to resist disease, and for use as tool to research in forward and reverse genetics. Genetically modified animals could pose ecological risk ...

Studies for Improvement of Reproductive Biotechnology for Production of Channel Catfish (Ictalurus punctatus) Female X Blue Catfish (Ictalurus furcatus) Male Hybrid Embryos

Perera, Dayan (2012-12-10)

Investigative studies were conducted on the relative effectiveness between carp pituitary extract (CPE), luteinizing hormone releasing hormone analog (LHRHa) injections and LHRHa implants for producing hybrid catfish ...

Targeted Gene Insertion and the Effect of Random Insertion of the Masou Salmon Delta5-Desaturase Transgene on n-3 Fatty Acid Production and Culture Traits of Channel Catfish (Ictalurus punctatus)

Huang, Yingqi (2018-11-07)

Channel catfish (Ictalurus punctatus) is one of the most abundant catfish species in North America. The objectives of this study were to determine the effectiveness of the Masou salmon delta5-desaturase transgene driven ...

Texture Analyses of Catfish: A Genetics Approach

Johnson, Andrew (2021-04-16)

Channel catfish (Ictalurus punctatus) and hybrid catfish (channel catfish ♀ × blue catfish (Icatlurus furcatus) ♂) aquaculture dominates the US aquaculture industry. These catfish genetic types have been heavily researched ...

Transgene Insertion of Cathelicidin Gene in Channel Catfish Ictalurus punctatus using CRISPR/Cas9 Knock-in Technology and Cathelicidin Activity Against Catfish Pathogens

Simora, Rhoda Mae (2020-04-22)

Protection of fish against infectious diseases is a major challenge in aquaculture, and economic losses due to these diseases limit profitability. Antimicrobial peptides (AMPs), a class of highly conserved peptides known ...
