3. How is sturgeon farmed?
1. Pond conditions: The pond must have a good water inlet and drainage system. The area of the fish pond should preferably be 3-5 mu, and a rectangular shape is best. The silt at the bottom of the pond should be less than 10 cm. If it is a cement flowing-water pond, its area is not limited to 50-300 m. The pond depth is 2 m.
2. Requirements for water quality: Dissolved oxygen should be greater than 5 mg/L, and pH should be between 6.5 and 8.0. It should be noted that sturgeon is particularly sensitive to chlorine; even a trace of chloride ions in the water can cause sturgeon death.
3. Fingerling stocking: Before stocking, the pond should be disinfected with quicklime, using about 10 kg per mu, and then the pond should be dried and sunlit. Water should be added two weeks before stocking, with a water depth of 2 m. The stocking density of sturgeon is related to its individual size. Generally, for a size of 300-500 g, 500 fish are stocked per mu. The water temperature that sturgeon can tolerate is 1-30°C. When the pond water temperature exceeds 26°C in summer, new water should be added in time.
4. Feeding management: Implement the feeding principle of fixed time, fixed place and fixed amount. The daily feeding rate is 3%, and then as the fish grows, the feeding rate gradually decreases. When the fish reaches more than 1 kg, the daily feeding rate should not exceed 1%. Because sturgeon is afraid of light, the feeding time is once each at dawn and dusk every day. Every half month, add fish health No. 2, freshwater fish multivitamins and enzyme preparations, etc., to improve the stress resistance and immunity of sturgeon and accelerate sturgeon growth.
Sturgeon is a relatively rare fish. If it is wild, it is best not to buy or eat it, and it should be purchased from regular fresh food markets.
