2. Dry pond wintering method. When the water temperature is below 10 degrees Celsius, drain the pool water, but ensure that the bottom of the pool is moist. In case of freezing cold, the surface of the pool should be covered with a layer of straw, wheat straw and other crops, insulation and antifreeze. The thickness of the cover should be at least 30 cm. The thicker the better.
3. Indoor wintering method. When the temperature is below 10 degrees Celsius, the pond-raised carp is turned to winter. In a room with a tank or bucket of 1 kilogram of salmon 2 kilograms of water, the eel is placed in a pond or bucket, changing the water once a day. Make sure the room temperature is between 2 and 5 degrees Celsius.
4. Shed wintering method. When the water temperature in winter is lower than 12 degrees Celsius, the effect of overwintering in a plastic greenhouse or greenhouse is very good. In the greenhouse, the water level of the pool should be equal to the aquaculture water level, and the temperature in the shed should be guaranteed between 2 and 8 degrees Celsius. When the temperature is highest at noon every day, the ventilation holes of the greenhouse are opened, so that the air in the greenhouse is fresh. Ventilation holes are installed at the top of the greenhouse to prevent death from carp oxygen deficiency.
5. Adding wintering method. Feeding turtles with feeds with high fat content before winter allows the carp to accumulate more fat for consumption during hibernation. Feeds with high fat content include cocoons, cockroaches, and fly maggots. Feed them as much as possible.
What is the method of wintering carp
1. Water overwintering method. The squid is a cold-blooded fish with a variable temperature (growth temperature 15 to 30 degrees Celsius) and is highly adaptable to the environment. When the temperature falls below 10 degrees Celsius, it rarely feeds and hibernates. At this time, for safe wintering of carp, the water level in the rearing pond should be raised to 70 to 80 centimeters to ensure that the water temperature in the bottom of the pool is above 0 degrees Celsius. If the pool surface is generally frozen, the ice must be opened every day to prevent the lack of oxygen in the carp. At the same time, on the basis of the original, deepen the water level to prevent icing.
