The farming methods and conditions of sturgeon are as follows:
1.Pond conditions: The size of the pond is best about 4 acres, and the bottom quality of the pond is best sandy, so as to provide a suitable substrate environment. At the same time, separate water intakes and drains are set up in the pond, and barbed wire is set at the water intakes and drains to prevent sturgeon from escaping. In addition, it is best to have a clean water source nearby, and it is best to choose live water aquaculture or mobile water farming.
2.Preparation for breeding: Before stocking, the pond needs to be prepared. First, the lime solution is sprinkled in the pond and soaked for about a week, then the water is drained and washed with clean water. After the cleaning is completed, refill the water level to 1The water depth is about 5 meters. After the pond is filled with fresh water, it cannot be stocked immediately, and it is necessary to wait for the disinfectant water to completely wear off to ensure the safety of the sturgeon.
3.Stocking: Before stocking sturgeon fry, the fry need to be disinfected. You can soak it in salt water or lime water for a few minutes and sterilize it thoroughly before cleaning. Before stocking, you can put in a few tails to test the water, observe whether there are adverse reactions, and confirm that the water quality is suitable before putting the seedlings in. For the seedling cultivation stage, the stocking density is generally 600 m2;For the stocking stage, the stocking density is 250 300 m2, and the stocking size is 15 20 g.
Sturgeon farming needs to pay attention to the following points:
1.Water quality management: Sturgeon has high requirements for water quality, and the water needs to be kept clean, at the right temperature, and rich in oxygen. Regularly test water quality indicators, reasonably release aquatic weeds or use biological filtration devices to maintain water quality stability.
2.Feed management: Choose the appropriate feed and feed it reasonably according to the growth stage and weight of the sturgeon. Pay attention to the quality and nutrient content of the feed, and avoid overfeeding or lack of nutrients.
3.Disease prevention and control: Check the health status of the sturgeon regularly and watch for abnormal behaviors or symptoms. If a disease problem is found, take corresponding prevention and control measures in time to avoid the spread of the disease.
4.Regular cleaning and maintenance: Regularly clean up the debris and sediment in the pond to keep the pond environment clean and tidy. At the same time, the maintenance and repair of breeding facilities are carried out to ensure the normal operation of the facilities.
5.Farming technology and experience: understand the relevant knowledge and technology of sturgeon farming, accumulate breeding experience, and pay attention to the latest developments in the industry at any time.
To sum up, sturgeon farming needs to pay attention to pond conditions, breeding preparation, fry stocking and culture management. Through scientific and rational management, the breeding efficiency and yield of sturgeon can be improved.
