Assembly and Annotation of the Channel Catfish Transcriptome and Assessment of Pervasive Expression

Jiang, Chen (2015-12-10)

For a long period of time, it was widely believed that only a small fraction of the genome is transcribed, and researchers were mainly focused on studying expression of protein-coding genes. In the last a few years, pervasive ...

Chemokine ccl33 is a key regulator of fish barbel development

Zhou, Tao (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

Drescher, David (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

Taylor, Zachary (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 ...

Odin, Ramjie (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

Yuan, Zihao (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 ...
