<\/span><\/span><\/p>\n

Koi, with its unique masculine beauty and brilliant colors is loved by more and more people and is crowned as the<\/span>\"King of the Ornamental Fish<\/span>\"The reputation of the koi. And its being a variable temperature animal, it can cause a lot of problems for koi keepers due to seasonal differences. So, what do you need to pay attention to in winter koi keeping?<\/span><\/span><\/p>\n

\n
\n
\n

First, before the cold air comes to do a good job of fish pool insulation work <\/span><\/p>\n<\/section>\n<\/section>\n<\/section>\n

<\/p>\n

In the south, the temperature is mostly suitable in winter and no special insulation measures are needed for the koi pond. However, the occasional cold air after a rainy day should not be ignored, as the sudden drop in temperature makes the temperature change large and is likely to have an adverse effect on the koi, which is a thermophilic animal.<\/span><\/p>\n

<\/p>\n

<\/p>\n

Koi do not require high water temperatures and are adapted to temperatures ranging from 2\u00b0C to 40\u00b0C, with the most suitable temperatures being 20\u00b0C to 25\u00b0C. The koi can not resist sudden changes in water temperature. However, they cannot resist sudden changes in water temperature. Koi can adapt to sudden changes between 2\u00b0C and 3\u00b0C. If the temperature difference exceeds this range the koi will become unwell or even sick.<\/span><\/section>\n

Therefore, before the cold air comes, you should do wind protection measures on the north side of the koi pond to avoid the direct impact of cold wind on koi as much as possible, and at the same time, you can also deepen the water level of the koi pond appropriately to keep the bottom temperature stable.<\/span>In the north, when the water temperature begins to drop sharply in early December, it is necessary to transfer koi fish fry from outdoor to indoor heated rearing, stocking density of 150~250 tails per square meter.<\/span><\/p>\n

<\/span><\/p>\n

<\/p>\n

Insulated rearing room can be a plastic shed, in the northern region to the house is appropriate. Generally, it is in the koi pond directly add warm water, but pay attention to the temperature of the transfer water, as far as possible to make the water temperature stabilized at 22 ~ 28 \u2103.<\/span><\/p>\n

In addition, when the temperature is even lower at night, special attention should be paid to temperature regulation, and the number and timing of water additions should be flexible according to the weather and water temperature.<\/span><\/p>\n

\n
\n
\n

Disinfect and stabilize water quality to prevent koi from \"catching colds\". <\/span><\/p>\n<\/section>\n<\/section>\n<\/section>\n

<\/p>\n

The change of seasons is often accompanied by rainy weather, which tends to cause sudden changes in water quality and the growth of parasites, so it is necessary to do a good job of disinfecting the koi pond. The better the quality of the koi, the higher the water quality requirements, regular use of chlorine dioxide, bromochloro hydantoin and other chlorine disinfection of the pool water, and after disinfection of about 5 days after the sprinkling of microbial agents such as bacillus preparations, to maintain stable water quality.<\/span><\/p>\n

If the water temperature is unstable, disinfection should be done every half month or even every week. In addition, the use of insecticides such as trichlorfon in conjunction with the actual situation of the koi can effectively prevent and control parasitic diseases.<\/span><\/p>\n

<\/p>\n

<\/p>\n

During the winter months, changing temperatures can cause koi to suffer from \"cold sickness\". Fish show abnormal activity, or weak swimming, or stagnation at the edge of the pool, or frequent jumping, or rubbing against each other. The above symptoms are mainly due to the drastic drop in water temperature caused by the change in air temperature, which is too late for the koi to adapt to, so it is important to prevent changes in water quality brought about by the change in air temperature in a timely manner and in a proactive manner.<\/span><\/section>\n

\n

III. Adjusting feeding levels and fishing with caution  <\/span><\/p>\n<\/section>\n<\/section>\n<\/section>\n


<\/section>\n

<\/p>\n

Koi are cold-blooded animals, and as the temperature drops, the amount of feeding should be adjusted accordingly.<\/span><\/p>\n

In early winter in South China, if the water temperature is around 18\uff5e20\u2103, feeding 2\uff5e3 times a week is enough; if the water temperature continues to decrease, the feeding amount should be reduced appropriately. If the temperature drops below 16\u2103, the koi starts to appear to stop feeding, then feeding can be stopped.<\/span><\/p>\n

When the water temperature is low, the oxygen-consuming bacteria in the water declines, the digestive enzymes in the intestines of the koi decrease, the metabolism slows down, and too much feeding is easy to cause indigestion, and although it will not die under normal circumstances, in the spring of the next year, the koi will only grow horizontally, resulting in obesity and extremely unattractive.<\/span><\/p>\n

As feeding is reduced and koi excrement is relatively small, the impact on water quality will not be significant, so the main focus is to refill with fresh warm water after winter.<\/span><\/p>\n

<\/p>\n

<\/p>\n

At this time of the year, if the koi are injured, it is easy to cause water mold disease, but winter is often the peak season for koi sales, and koi are fished more often, so a little carelessness can cause injury to the body of the fish. In this regard, when catching koi, be sure to use the net to gently pick up the koi in the direction they are going, which is both accurate and fast, and will not easily hurt the fish.<\/span><\/section>\n
On the contrary, if the old net in the koi after the chase to retrieve, the net in the water with resistance, the force of the chase easy to touch the fish, will give the invasion of germs will provide an opportunity, so try to avoid the operation of inadvertently touching the body of the fish.<\/span><\/section>\n

<\/p>\n

For how to winterize pool raised koi, pay attention to the following points:<\/span><\/p>\n

1. Ensure that the surface of the koi pond does not freeze all the way;<\/span><\/p>\n

2. If the surface of the fish pond is completely sealed, punch air holes in the ice;<\/span><\/p>\n

3, koi pond filtration system should also be always open, according to the temperature changes can be reasonably adjusted filtration system running time.<\/span><\/p>\n

<\/span><\/p>\n

With the colder winters, you need to take extra care when buying and selecting fish. There are a lot of diseased fish purchased by fish merchants in the winter, and there are also temperature differences that should not be ignored.<\/span><\/p>\n
