Abstract: Sturgeon is one of the oldest fishes in the world. Due to the delicious and nutritious flesh and caviar, sturgeon has extremely high economic value. Because of the price of caviar kept very high, breeding female sturgeon should get higher economic prospect than male. It seems impossible to identify the sex according to the exterior condition because of the similarity of sex characteristic on sturgeon. Currently, sex of immature sturgeon is usually identified through the ultrasonic instrument or with the help of endoscope. Even so, the accuracy of the identification cannot be ensured. Using molecular techniques to investigate sex determination and differentiation of sturgeon is supposed to conducively develop the technology of identifying sex and achieve the full female breeding. In this paper, the research status of genes related to sex determination and differentiation of fish is summarized, then the research progress on genes related to sex determination and differentiation of sturgeon is reviewed, and the feasible future research direction is also predicted.
