Yellow catfish is a freshwater fish with significant aquaculture value. The study of its reproductive biology is of great significance for improving the efficiency of artificial breeding and achieving sustainable aquaculture. This study reviews the latest research progress in reproductive biology of yellow catfish, including reproductive system anatomy and development, endocrine regulation, gametogenesis and oocyte maturation, artificial induction reproduction and seedling breeding, reproductive behavior and environmental adaptation, as well as genetic improvement and molecular breeding. The role of the HPG axis and sex hormones in reproduction was emphasized and expounded. The molecular mechanism of oocyte maturation and the influence of gamete quality on fertilization rate were analyzed. Technical breakthroughs such as induction of labor and hatching were summarized. Meanwhile, the influences of environmental factors such as temperature, light and water quality on reproductive efficiency were discussed, and the potential of genetic breeding technology to improve reproductive traits was explored. Finally, the application prospects of these advancements in aquaculture are prospected, and it is pointed out that these studies provide important scientific basis for efficient artificial breeding and sustainable aquaculture of yellow catfish.
