We sequenced and characterized the complete mitochondrial genome of Channa argus, Channa maculata and their hybrid [C. maculata (♀) and C. argus (♂)]. All the three mitochondrial genomes contained the typical complement of 13 protein-coding genes, 22 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs) and 1 control region. The entire mitochondrial DNA (mtDNA) molecule of C. maculata was 16,559 bp long while the complete mtDNA molecule of C. argus and hybrid snakehead fish was 16,558 bp long. This is the first report on the complete mitogenome sequence of C. maculata and hybrid snakehead fish.

The albino northern snakehead (Channa argus) is an aquaculture species characterized by heritable albino body color, in contrast to the typical coloration. Additionally, there are gray- and golden-finned individuals, which exhibit distinct coloration in their caudal fins. We performed RNA-seq to profile the transcriptome of caudal fin tissues in albino gray-finned and golden-finned C.

The evolutionary origins of specialized organs pose significant challenges for empirical studies, as most such organs evolved millions of years ago. The Northern snakehead (Channa argus), an air-breathing fish, possesses a suprabranchial organ, a common feature of the Anabantoidei, offering a unique opportunity to investigate the function and evolutionary origins of specialized organs. In this study, a high-quality chromosome-level reference genome of C.

The mitogen-activated protein kinase (MAPK) signaling cascade, integral to cellular regulation, orchestrates cell growth, differentiation, stress response, and inflammatory reactions to adapt to challenging environments. The northern snakeheads (Channa argus), a valuable freshwater species known for its hypoxia tolerance, rapid growth, and high nutritional value, lacks comprehensive research on its mapk gene family. In this study, we identified 16 mapk genes in northern snakeheads, among which mapk8, mapk12 and mapk14 have duplicate copies.

Background: This study investigates the effect of microemulsions of 0.8% Ocimum basilicum essential oil (MOBO) on the cooking quality and shelf life of snakehead fillets using different impregnation methods (air environment treatment, vacuum impregnation, ultrasonic impregnation and vacuum impregnation with ultrasonic-assisted). Basil essential oil, recognized for its antimicrobial and antioxidant properties, is utilized in a microemulsion form to enhance its efficacy and application in food preservation.
