Channa plays an important role in Asian aquaculture, but it faces many challenges in the process of transitioning from wild populations to artificial breeding, such as poor adaptability, strong aggressiveness, slow growth, and low reproductive efficiency. In recent years, many studies have been carried out at home and abroad on the domestication and genetic improvement of Channa, including growth traits, sex control, stress resistance and other aspects. Existing studies have shown that methods such as GWAS, genome selection, and transcriptome analysis have gradually been applied to the screening of key genes and traits; some studies have also explored breeding methods such as probiotic feeding, hormone induction, and interspecific hybridization. Studies have pointed out that artificial breeding may lead to a decrease in genetic diversity, which is also a direction that needs to be monitored in the future. This study clarified which key traits in the domestication of Channa deserve special attention, and also provided a genetic basis for the formulation of subsequent breeding strategies.
