Embodiment 1
[0014] On January 18, 2001, 150 Chinese sturgeon fry were transported from Wuchang to Qingdao, weighing 5.55-9.29g and body length 10.8-14.0cm. The aquaculture water is used after 20 hours of air filling with tap water. The water is changed 3 / 4 of the day and the water temperature is 8°C. Domestication began on February 3, and the salinity of aquaculture water increased by 5‰ every three days, and the salinity of aquaculture water reached 15‰ on February 11; it increased by 3‰ every five days, and the salinity reached 25‰ on February 27, after 15 days After domestication, it will increase by 1‰ every three days from March 15th, and it will safely transition to 32‰ of seawater on April 4th.
[0015] In addition, through experiments, in the process of seawater domestication, the salinity of aquaculture water can be increased by 3 to 5‰ every three days before 15‰; when the salinity is between 15 and 25‰, it can be increased by 1 to 3‰ every five days; When the water salinity is 25‰,...
