Abstract: Sturgeon is a kind of large economic fish. Due to overharvesting, habitat destruction and their biological characteristics such as sexual maturation at a late age and low survival rate of larvae, sturgeon natural resources in the world were depleting. In order to meet the needs of sturgeon caviar and meat, artificial cultivations were developed and had been the main source of sturgeon products. So far, there was not yet a perfect germplasm identification method in sturgeons at home and abroad. Some common sturgeon germplasm identification methods were summarized. The advantages and disadvantages of each method were analyzed and listed. It was helpful to establish a stable and reliable sturgeon germplasm identification method.
