The dominant shrimp species in commercial breeding are widely introduced and spread worldwide, and their systematic geographical pattern and diffusion paths have attracted much attention. This study combines the progress of molecular phylogenetics and population genetics in recent years, and reviews and analyzes the phylogenetic relationship, natural geographical distribution, artificial introduction history and cross-regional transmission patterns of major economic shrimps. The results show that the Indo-Western Pacific region is the center of origin of most marine shrimps, and there is obvious geographical differentiation of populations in different oceanic regions, and marine barriers restrict gene communication. Human farming activities have accelerated the global spread of shrimp species, but have also caused problems such as germplasm mixing, decline in genetic diversity and alien invasion. Molecular marker analysis revealed the genetic structural characteristics, population differentiation levels and environmental adaptation signals of major farmed shrimp species. In the context of global climate change, the driving role of environmental factors (such as temperature, salinity) on the geographical distribution of shrimp is becoming increasingly prominent. This study systematically sorted out the research progress of the global systematic geographical pattern and transmission model of commercial important shrimps, and pointed out the importance of strengthening genetic diversity protection, standardizing international seedling trade and preventing and controlling disease transmission for the sustainable development of the industry.
