How to breed yellow and spicy tench, you need to start from the following links to raise it well.
1. Fish pond construction.
Breeding Huang Lading needs to choose a sheltered from the wind and sun, sufficient water source and convenient drainage location to build a fish pond, the area should not be too large, generally 2-5 acres is appropriate, the water depth is 1Between 5-2 meters is preferred. The inner wall of the fish pond needs to be jointed with cement, and anti-escape facilities should be prepared. Fish traps should be installed at the inlet and outlet to facilitate management.
2. Cleaning pond disinfection.
Before stocking the fish pond, it is necessary to thoroughly disinfect the pond. When clearing the pond, the silt at the bottom of the pond should be removed and exposed to the sun for a period of time. When disinfection, disinfectants such as quicklime or bleaching powder can be used to sprinkle the whole pond to kill germs and predators.
3. Seed stocking.
The stocking time of the seedlings is generally in April-May or September-October every year, and the stocking density is 1000-3000 per mu. When selecting fry, it is necessary to choose fry that are robust, neat and disease-free. Before releasing the fry, the fry need to be soaked in 5% saline solution for 5-10 minutes to sterilize.
Fourth, bait feeding.
The bait of Huang Lading mainly includes fresh animal feed and artificial compound feed. When feeding, it is necessary to feed reasonably according to the feeding Xi and growth of yellow spicy ding. In the breeding process, vitamins, minerals and other nutrients should be added to the bait regularly to meet the growth needs of Huang Lading.
5. Daily management.
Daily management is one of the key links in the cultivation of yellow and spicy dice. It is necessary to regularly inspect the pond to observe the changes in the water quality of the fish pond, the feeding situation of yellow and spicy ding, and whether there are diseases. In the high temperature season, it is necessary to pay attention to prevent the occurrence of hypoxia and floating head phenomenon, and turn on the aerator in time to increase oxygen. At the same time, the fish pond should be cleaned and disinfected regularly to keep the water quality of the fish pond fresh and hygienic.
6. Disease prevention and control.
The disease prevention and control of Huang Lading is also one of the important links in the breeding process. Fish ponds should be disinfected regularly to maintain stable and hygienic water quality. When a disease is found, it is necessary to take timely measures to carry out ** and treatment. Common diseases include water mildew, bacterial gill rot, etc., which can be treated with antibacterial drugs and anti-inflammatory drugs. At the same time, it is necessary to pay attention to avoid the use of drugs that are sensitive to yellow spicy dining, so as not to cause adverse consequences such as drug poisoning.
In short, the cultivation of Huang Lao Ding needs to master certain technology and experience, pay attention to daily management and disease prevention and control work, maintain the freshness and hygiene of water quality, and reasonably feed bait to meet the growth needs of Huang Lading. Only in this way can we improve the efficiency of breeding and product quality, and realize the sustainable development of aquaculture.
