How to spend the winter in koi fish, and what should we pay attention to?
If it's inconvenient, wind the fish pond.
Ensure water quality: Keeping a good and stable water environment can prevent colds in koi fish.
Breeders should disinfect and change water regularly to maintain water quality.
Reduce feeding: The temperature in winter is low, and koi fish's appetite for food is low.
Breeders can reduce the frequency of feeding food and prevent food surplus and water pollution.
First, the temperature difference between day and night is large when the fish pond is insulated in winter, and there will be cold air coming. Therefore, breeders should pay attention to the windproof of fish ponds to prevent cold air from affecting koi fish.
In addition, warm water can be added to the fish pond, and the water temperature can be kept at about 25 degrees, so that the feeding water level can be appropriately deepened to ensure sufficient dissolved oxygen.
If conditions permit, koi fish can be transferred to indoor culture.
Second, ensure the cleanliness of water quality. Koi fish has high requirements on water quality, and polluted water is likely to cause them to have cold symptoms.
When koi fish is ill, he will be listless, lose appetite and be unable to swim. Therefore, breeders should regularly disinfect fish ponds to prevent such diseases.
Third, reduce the amount of food feeding. koi fish's appetite is affected by the water temperature.
In winter, the temperature is relatively low, so their food feeding amount should be adjusted according to the different water temperatures.
When the water temperature is about 20 degrees, it can be fed 2-3 times a week. When the water temperature drops, the feeding amount will also drop.
If the water temperature drops below 10, koi fish will stop eating, and farmers need to stop feeding food.
If the water temperature is very low, the breeder should adjust the water temperature appropriately and observe whether koi fish is short of oxygen.
