1. How to raise koi in winter

In winter, the weather is quite cold. When the temperature drops to 0℃, the koi should be transferred to the indoor fish pond in time for wintering. The indoor water temperature should be kept at 2℃～10℃. Pay attention to heat preservation, proper feeding, fat preservation and disease prevention. The period from November to March of the following year is the wintering period of koi.

When cold air strikes, insulation work should be done well. In the south, the temperature is relatively suitable most of the time in winter, and no special insulation measures are needed for koi. However, occasional cold air can also cause large temperature changes, which can easily have adverse effects on koi.

Under conditions of suitable water temperature, make sure that the koi are well fed and well-fed. If they are not fattened or do not get enough nutrients, it will be difficult for the koi to resist the low temperatures in winter.

Additional information

1. The water for Koi must be exposed to the sun or trapped before entering the tank. Expose it to the sun for one day, or air it for three days.

2. Pay attention to the water temperature difference when changing water. The water temperature difference exceeds 2 degrees. Koi can adapt to 5-30 degrees Celsius, but cannot adapt to sudden changes in water temperature.

3. It is best to keep fish in a bare tank, which means that no water plants, sand, stones, etc. should be placed in the tank.

4. Koi have a large appetite and produce a lot of excrement, so filtering and oxygenating equipment are a must.

5. Depending on the water quality, change the water every 3 days, changing one-third of the water each time.

2. How to raise koi in winter

Koi is a relatively easy fish to raise, and it does not require much in terms of environment and food! But there are still some things to be careful about. When the water temperature is below 5 degrees for a long time, you should pay attention to heat preservation. Protein should be added to the food in moderation. Koi also has another characteristic, that is, its size is proportional to the area where it is raised! If you keep it in a fish tank, it will not be very big, but it can grow very big in a fish pond.

3. How to raise koi in winter?

Stop feeding and do less frequent water changes.

1. Pay attention to keeping warm when cold air strikes

In Guangdong, in many areas, the temperature is relatively suitable most of the time in winter, and no special insulation measures are needed for the fish. However, cold air occasionally hits, and the temperature changes greatly, which can easily have adverse effects on the fish. Therefore, when encountering cold air such as the current one, pay attention to blocking the wind on the north side of the pond to avoid the cold wind from affecting the fish. At the same time, you can appropriately deepen the water level of the fish pond to keep the bottom temperature stable. In a relatively stable winter, keeping warm is relatively simple, but it should not be taken lightly.

2. Just like people, sudden changes in weather can easily lead to colds, and so can fish. Therefore, it is necessary to disinfect and stabilize the water quality regularly to prevent Koi from catching a cold. When the seasons change, it is often accompanied by rainy weather, which can easily cause sudden changes in water quality. In addition, the water temperature in early winter in South China is suitable for the growth of most freshwater fish parasites, so it is necessary to disinfect the fish pond. To maintain stable water quality. In seasons with relatively constant water temperature, disinfection once a month is generally sufficient. If the water temperature is unstable during the season change, the number of disinfections can be adjusted to once every half a month or even once a week. In addition, the use of insecticides such as trichlorfon according to the actual situation of the fish can effectively prevent and treat parasitic diseases. When the temperature changes, Koi are prone to catching a cold, and the fish show abnormal activity, or swimming weakly, or stagnating at the edge of the pond, or jumping frequently, or rubbing against each other, etc. She said, "The above symptoms of fish are mainly caused by sudden changes in temperature and the fish have no time to adapt, or the water quality is poor and there are parasites." Sprinkling the whole pond with sea salt to increase the salinity of the breeding pond water to 5/1000 can effectively prevent koi "cold disease". Although disease prevention is something that should be paid attention to at any time, it should be paid special attention in winter."

5. What should we pay attention to when raising koi in winter?

The amount of food you feed can be reduced appropriately. Also, if you keep it outdoors in winter, it is best to move it indoors.

6. How to keep koi from dying in winter?

Should I raise them in a pond or a tank? Koi fish require very normal water quality and water temperature, either slightly acidic or slightly alkaline - the color will be more beautiful if it is slightly alkaline; the water temperature must be above 2℃ and below 33℃.

If you keep them in a tank, you usually use a heating rod for wintering, and keep the temperature constant at 24-26℃ or 26-28℃ (you can choose one of them, but not 24-28℃, because the temperature span is too large, and a water temperature difference of more than 4℃ can easily cause a cold); if you keep them in a pond, you can deepen the water, and grow some floating plants (duckweed or water lilies) on the surface of the pond. When encountering an emergency cold wave, you can spread some dry straw on the water surface - note that when growing floating plants or laying straw, you only need to lay 1/3 to 1/2 of the water surface, and never fill the entire pond to avoid hypoxia on the bottom of the water - there are now special pool constant temperature systems, which are said to be effective, you can try it.
