Tilapia has excellent adaptability, rapid growth and high nutritional value, and has become an important freshwater breeding species. However, intensive breeding and artificial breeding have led to the gradual loss of genetic diversity of tilapia species. This study takes tilapia strains from different continents as the research object, and displays the genetic structure and domestication history of tilapia populations through genetic analysis. Research background shows that African native populations retain high genetic diversity, while in introduced areas such as Asia and the Americas, there are obvious genetic differentiation and characteristic differences due to artificial breeding and environmental pressure. The research hopes to clarify the global diffusion path and domestication process of tilapia, find out the genetic variants and genetic markers related to economic traits during domestication, provide a scientific basis for the sustainable management and protection of tilapia genetic resources, and explore the potential of future intercontinental cooperative research, thereby promoting the long-term development of tilapia breeding technology.
