This is a marine migratory fish. From September to November every year, it goes up the Yangtze River from Haikou to the area from Jinsha River to Pingshan to breed. The hatched cubs grow in the river for a period of time and then return to the Yangtze River estuary to be fattened. The migration of Chinese sturgeon is a reproductive migration.

The migration of migratory fish is a typical and true migration of fish, and it is a basic attribute of this type of fish. If migratory fish cannot complete this migration or their migration is hindered, the life cycle of these fish will be destroyed, affecting the proliferation of the population and even the survival of endangered species. The reason for fish migration is due to the physiological requirements of the fish themselves, including the pursuit of bait-rich waters, suitable spawning grounds or overwintering sites. Environmental factors that affect fish migration include water flow, bottom shape, temperature, salinity, water quality, light, etc. Among them, water flow is the factor that plays a decisive role in the direction of migration. Under conditions with a certain flow speed, fish usually swim against the current.
