What fish do you keep in an outdoor fish pond in winter? What kind of fish do you keep in an outdoor

Due to the low water temperature of outdoor fish ponds in winter, it is necessary to select some fish that are hardy and adapt to low temperatures for farming. Here are some fish that are suitable for farming in outdoor fish ponds in winter:

1.Goldfish: Goldfish is a very hardy fish that can adapt to low temperatures in the water. At the same time, goldfish are not particularly picky about water quality and can live in general tap water.

2.Koi: Koi fish are very adapted to low temperatures and can survive in temperatures of minus a few degrees Celsius. At the same time, koi fish also have strong disease resistance and adaptability.

3.Grass carp: Grass carp is a common freshwater fish with strong cold tolerance and adaptability. In low temperatures, grass carp will reduce their activity but will not die.

4.Carp: Carp is also a hardy fish that can survive in low temperatures. At the same time, carp have strong adaptability and disease resistance.

5.Red crucian carp: Red crucian carp is a freshwater fish that adapts to low temperatures and can survive in lower water temperatures. At the same time, red crucian carp is not particularly picky about water quality and can live in general tap water.

In conclusion, when choosing fish to be raised in outdoor fish ponds in winter, it is necessary to consider many aspects such as cold tolerance, adaptability and disease resistance of the fish. At the same time, it is also necessary to pay attention to water quality management, change the water regularly, and keep the water clean.

Outdoor fish ponds raise grass goldfish.

In winter, if you don't want to freeze the ice, if the water temperature is more than 2 degrees, you can raise koi.

Outdoor fish ponds are passed by higher aquatic plants.

The adsorption effect removes or reduces nitrate and nitrite in water.

The content ensures that the fish pond is clean and pollution-free water, which reduces the occurrence of fish diseases, and also reduces the frequency of water change and the number of cleaning filter materials, and reduces the work intensity.

1. In winter, if the water temperature is above 2 degrees, you can raise koi.

2. If it is close to the freezing water temperature, you can raise goldfish.

3. If you are frozen, raise some grass carp and carp or something.

4. Goldfish, goldfish are generally fine at 0 degrees water temperature, and many varieties can live in frozen water.

In winter, if you don't want to freeze the ice, if the water temperature is more than 2 degrees, you can raise koi.

The outdoor fish pond removes or reduces the content of nitrate and nitrite in the water through the suction action of higher aquatic plants, ensures that the fish pond is clean and pollution-free water, reduces the occurrence of fish diseases, and also reduces the frequency of water change and the number of cleaning filter materials, and reduces the work intensity.

Precautions for outdoor fish farming:

In order to prevent the water temperature from being too high due to direct sunlight in summer, it is necessary to erect a shade canopy. The canopy should be 1 m or 2 m above the pool wall and have some resistance to wind and rain. The shed is shaded by vine cash crops or flowers such as grapes, loofahs, and pumpkins.

5 days before stocking, 20 grams of bleaching powder per cubic meter of water were evenly sprinkled for fish pond disinfection. Before the goldfish enter the pool, the fish body is soaked in 3% salt water to sterilize. Generally, the stocking amount per square meter of longan, high head, Wangtian and other varieties is, the body length is 2 cm 100 tail 200 tails, the body length is 5 cm 50 tail 100 tails, and the body length is 10 cm 10 tails 20 tails.

Fry can be propagated by themselves or purchased.

1. Silver carp. Silver carp is one of the four major fish, and it is also an excellent fish species suitable for breeding, and its own distribution is extremely wide, so there is no problem in raising fish ponds in various places. Its growth rate is relatively fast, and it is not easy to get sick, and the yield is still very high, usually in the way of interbreeding, and can be raised in a fish pond with carp, grass carp, etc.

2. Bighead carp. Like silver carp, bighead carp is also a member of the four major fish, and both are filter-feeding fish, mainly eating plankton. This fish, also known as fathead fish or big-headed fish, lives in the upper layer of the water body and is a warm-water fish, which can be better raised in fertile water bodies, and is also very suitable for interbreeding.

Fish do not have strict requirements for water temperature and water quality. The water temperature in which the fish live is 20-30 degrees. Although fish are highly adaptable to the environment, they have the weakness of not being able to resist sudden changes in water temperature.

The water temperature rises and falls at 2 3 degrees Celsius, otherwise the fish are prone to illness, and when the temperature rises and falls 7 8 degrees, the fish do not eat at the bottom of the water and do not move. If the changes are more severe, the fish will even die immediately. When the water temperature is 20-25 degrees, the fish swim actively, have a strong appetite, have a strong physique, and are brightly colored.

Therefore, it is best to use a heating rod in winter and put it in a ventilated and cool place in summer to control the temperature that is most suitable for the growth of koi, so that the fish can have a comfortable environment and grow rapidly. Fish need oxygen to absorb nutrients to produce energy to sustain life in the water, so having enough oxygen is the key to fish farming. Note that it has been proven that the higher the water temperature, the more oxygen is consumed.

Fish are also suitable for living in slightly alkaline, low-hardness water quality environments.

In nature, that is, in the wild, these fish go through the four seasons, which means that their temperature will gradually change from high to low. Even if it is artificially bred now, there is still such a gene in the bones, which is what we call "something in the bones" in albinism. But if we keep it at home, the temperature in the fish tank is naturally higher in the summer, but I don't add it to a more suitable temperature in the winter.

It's equivalent to that they've been growing up in greenhouses. Then in the long run, there will be a problem, the physique will decline, and the resistance will not be so high. It seems to be providing them with a good environment, but is it actually harming them?

You can't grow towering trees in the greenhouse

Just like the trees in the greenhouse can't grow into big trees, and the courtyard can't run out of horses. Even if we humans have a good environment, we will catch a cold once a year. And if ornamental fish grow up in a greenhouse from childhood to adulthood, then if the water quality changes or there are some fluctuations, they are likely to collapse all at once.

Thinking of this, I would like to put forward a point of view, or a suggestion for everyone. In winter, we can also try to imitate the wild environment, of course, the temperature does not need to drop too low, but also do not adjust to such a high 24, you can have a cherry blossom feast of about 18 to 20 degrees Celsius. Because in the native environment of tropical fish, although Yuyin said that the perennial temperature is about 25 degrees.

But she will inevitably have some moments, such as at night or when the temperature will be cooler. Then we try to mimic the environment as much as possible. In other words, don't let the fish at home live in a very comfortable environment all the time, and create some small difficulties appropriately can improve their survivability.

Outdoor fish ponds raise grass goldfish.

In winter, if you don't want to freeze the ice, if the water temperature is more than 2 degrees, you can raise koi.

The outdoor fish pond removes or reduces the content of nitrate and nitrite in the water through the suction action of higher aquatic plants, ensures that the fish pond is clean and pollution-free water, reduces the occurrence of fish diseases, and also reduces the frequency of water change and the number of cleaning filter materials, and reduces the work intensity.

1. Grass-seeded goldfish.

It is also known as the golden carp species. It is the ancestor of the goldfish, with a body similar to that of a crucian carp, a flattened spindle-shaped body, a normal dorsal fin, and a single caudal fin. There are two types of grass species, one type is the golden carp type, and the other is the long-tailed dovetail type.

2. Classical goldfish.

Generally, the body is shorter, each fin is longer, and the dorsal fin is bifurcated, and the caudal fin is bifurcated into four; The eyeball is straight and does not protrude. Precious varieties include crane top red, pearl, tiger head and so on.

There are six major types of cultures: the top of the head is smooth and salmon-shaped; Sarcoma with the top of the head is high-headed; The sarcoma on the top of the head is well developed and enveloped around the cheeks, and the eyes are sunk in the flesh and are tiger head type; The nasal membrane is well developed and forms a double pom-pom type, which is pom-pom-pom; operculum inverted growth into revolt; The outer blister of the eye with translucent blisters is blister-shaped.

3. Koi. With the improvement of the quality of life, many families will raise some fish after renovation to increase the environmental atmosphere. Generally, koi fish are chosen, and the reason for choosing koi is because it is easier to raise.

It is best to match an aeration pump, turtles are recommended not to be mixed, large turtles (more than ten catties) will hurt the fish, small turtles into the water is relatively deep, water turtles and turtles are generally raised in the water without back armor, of course, if you put a few sundecks and big stones into it, you can also raise, but pay attention to the time when the turtle needs to hibernate, I personally recommend that the pool group koi carp, very beautiful, look comfortable.

If you keep it outdoors, you should raise koi fish and grass gold.

Can it solve your problem?

I'm also in Wuhan, and it's a similar situation, but I want to raise something special.

1. Goldfish.

Goldfish are cold-water fish, they can survive at low temperatures,14 they can be alive and kick around, and they can survive at low temperatures, but their vitality will be much worse. Although goldfish is a cold-water fish, it can be full of vitality in room temperature water (25), and it is an out-and-out durable fish. At the same time, goldfish do not have high requirements for the environment, and they can be raised in bare tanks.

The key one is that the cost of raising goldfish is low, and a butterfly-tailed dragon is only about 30.

2. Koi. Koi fish are as hardy as goldfish, or even better. However, one of the disadvantages of koi is that it eats a very large amount, and mature koi eat more than 2 adult goldfish. The more you eat, the more you come.

This is also the main reason why koi fish are rarely popular among players.

3. Chinese betta fish.

As a native breed, betta fish has always been tepid in the aquarium world, and is often eliminated as a marginal species, just like the Chinese pastoral dog in China. But it is undeniable that betta fish are not only easy to raise, but also very ornamental. Especially in the low temperature and temperature environment of winter, betta fish can live tenaciously and vigorously.

4. Tang fish. Goldfish or white cloud redtail fish, there are many people who understand. Tang fish is a unique species in Baiyun District, Guangzhou, and is not found anywhere else. From the first discovery of the tangyu, to the establishment of a protected area due to endangerment, to today's prosperity, the fame of the tangyu has flattened amid the skyrocketing.

Now Tang fish can be artificially cultivated, and the selection of varieties is very diverse, ** is also close to the people, is the most suitable for raising small pet fish in winter.

It's definitely going to be some good-looking, easy-to-raise goldfish. Goldfish are cold-water fish and do not need to be heated. Koi fish can also be raised.

However, the average goldfish is more expensive. The best tropical fish to raise is the gar, he is also called a small crocodile, and it can not be heated in winter, not fed, and will not die. It's just that it doesn't grow.

Boiled fish, boiling fish is the best, with you through the long winter.

It is recommended that you usually collect some plastic foam boards, so that they can be used to make insulation for some things that are afraid of freezing in winter.
