Sturgeon is a valuable fish. It may take seven or eight years to raise caviar, but the income is also very considerable. Caviar is the gold price sold by the gram. Sturgeon has high requirements on water quality and environment, and the culture technology is not clear at once. I suggest you buy a professional book on sturgeon culture technology to study it. It would be better if you could find someone with culture experience. In the aspect of water quality management, the intelligent aquaculture system of Yiyubao is used to monitor the water quality data in real time, which can be queried at any time on the mobile phone computer. The quality is good, and the main operation is simple and easy to use.
The healthy and disease-free sturgeon fry should be selected for fry stocking, and the body length should be more than 20 cm. Generally, the stocking density of large-sized fry is 400-600/mu. When releasing seedlings, we should not only consider the appropriate water temperature, but also consider the listing of adult fish. Feeding of fry should be stopped1-2 days before transportation. During transportation, 38×82 polyethylene packaging bags should be selected, 3/5 water should be added in the bags, and the water temperature should be adjusted to12-15℃ with ice cubes. Twenty fry with a body length of 20-30 cm should be put in each bag, and then packaged and transported. If the transportation time is less than 8 hours, you can transport it by water truck, but you should always pay attention to the change of water temperature during transportation, and the effect is also good. Two days before releasing the sturgeon, the water should be tested first, and the fry 10 of the same specification should be put into the cage to observe the activity of the sturgeon. If there is no abnormality, the fry can be released. When releasing seedlings normally, do not unpack the arrived seed bags first, but put the whole bag into the pond, slowly make the water temperature in the bag close to that in the pond, and then open the bag mouth to put the seeds into the pond. Conditional farms, it is best to pour fish with water into a big barrel to keep continuous aeration, then put salt in the barrel to make the salinity reach 2%, soak the fish body 10 minutes and then put the seedlings into the pool.
Feed feeding pond culture is mainly based on compound feed, and sturgeon fry have not yet formed the habit of feeding in a fixed place when they just go down to the pond, so they should be domesticated in time. Feed can be put on the feed table to improve the utilization rate of feed and facilitate daily observation. Some sturgeons, such as sturgeon schrenckii, hybrid sturgeon, Russian sturgeon, Chinese sturgeon, etc., have the characteristics of phototaxis at night, and can be illuminated near the feed table when domesticated at night. Feeding should adhere to the principle of small amount and multiple meals, the feed should be palatable, and the particle size should not be too large or too small. Generally, it is better to use1/2 of fish. The feeding amount is about 3% of the fish's body weight, and it is fed 3-4 times a day, and the feeding amount can be adjusted at any time according to the specific situation.
