How to increase the survival rate of winter fish

First, cultivate healthy fish species and ensure fish species specifications:
Feed some high-protein feeds before winter and try to improve the fish size and plumpness.
Second, ensure that the winter water quality of the species is excellent, and create a good wintering environment:
1. Pond selection: 2 to 5 acres in area, 10 to 20 centimeters thick sludge at the bottom of the pool, no weeds in the pool, and a pond with strong water retention. Keep the water depth above 2 meters and maintain a stable water level. In the cold season, the water level should be increased to increase the water volume. Maintaining a relatively stable water temperature is an effective measure to reduce the overwintering mortality of fish species.
2. Water Quality Requirements: Before the fish species enter the pond, the pond should be filled with fresh water after adding 80 kg of fresh lime clear pond. The water inlet should be filtered with a dense mesh to prevent wild fish from mixing. Use 2 kg of urea per acre. Do not apply organic fertilizer to avoid polluting the water. The food organisms in winter fertilizers are not only used for fish to supplement metabolic consumption, but also can maintain rich dissolved oxygen in the pool water due to photosynthesis of phytoplankton.
Third, timely pool, avoid fish injuries:
Every November, when the water temperature falls to 7 to 10 degrees Celsius, the fish species have basically stopped feeding. At this time, it is best to choose sunny and warm weather. When fingerlings enter the pool, apply 3 to 5 percent salt water to soak the fingerlings for 5 to 10 minutes. Disinfection of fingerlings is a practical and effective method of cutting off pathogens and preventing fish diseases.
Fourth, determine the reasonable stocking density:
There are 30,000 to 40,000 species of fish 10 centimeters per acre, 20,000 species of 13 centimeters, and no more than 10,000 species of 16 centimeters.
Fifth, strengthen wintering management:
1. Maintain better transparency. After the snow is over, it is necessary to remove the ice area in time to avoid affecting the photosynthesis of phytoplankton and maintain sufficient dissolved oxygen in the water.
2, often determine the amount of dissolved oxygen in the pool water. Dissolved oxygen is best kept at more than 3 milligrams per liter. If it is less than 2 milligrams per liter, it means there is already an oxygen deficit. Emergency flushing is needed.
3, after the fish species under the pond, should adhere to the appropriate winter feeding, with powdered cake or compound feed as well. The water temperature is above 5 degrees Celsius and it is fed once every 3 to 5 days. The amount fed is 0.5 to 1.0 percent of the body weight of the fish. If continuous sunny weather should increase the amount of feeding. After the spring, when the water temperature rises to 10 to 15 degrees Celsius, normal management such as feeding and fertilization can be performed.
