Japanese koi Chinese koi that is good?

Carp originated from Pis in Central Asia and was later introduced to Japan via China and Korea. In Japan, koi fish have been improved for ornamental use, so koi can be said to be a pure Japanese work of art. The ancestor of the koi is the common edible carp, which is said to have made the ornamental koi fish what it is today.

Koi fish originated in 20 villages, including Yamakoshi Village and Uonuma Village near Naka Ward in Niigata Prefecture, Japan, and is now part of Kochiya City. From October to December every year, koi lovers from all over the world gather here to buy their favorite koi fish and to visit the world-famous "birthplace of koi". So I think it's better to be in Japan, after all, it's the birthplace,,, and even though I'm a little Japan, I can't erase history because of that.

It is a Chinese carp, but it was improved in Japan and cultured to have a color, and there is the koi fish that we have today. It has a history of 200 years in Japan.

It's still better than Japan!

Although our country also has but it is not as good as others, I only had a koi fish born in China two months ago, and then I saw a very good fish at a pet fair here, the body color, body shape and even the eyes are better than other fish! The fish seller did say that it was shipped from Japan, and I bought this one (10 pieces of more than a bundle of more than 10 pieces of money) for 200 yuan or so, and although I went home and hung a few, the rest were better than before!

I'm more patriotic, and although I haven't eaten it, I insist that the ones in my hometown are much better than those in Japan.

I think it's good for China!

The water in Japan is salty and not as alkaline as in China.

Japan's good, China's garbage.

I don't know how to say this! It's like a beauty, ringed fat and thin, each with its own goodness, so it can't be compared!

As long as you like it, it's good to be able to accept it! Every koi fish has a good side to him!

First, ** is different.

1. German koi: It is a koi produced by crossing the leather carp produced in Germany and the Japanese koi.

2. Japanese koi: It is a mutant species produced by long-term selection and breeding of carp.

3. Zhonghe Kuanzi koi: It is rumored that koi originated from Longzhou koi in Guangxi, Jiangxi Xingguo red carp, and Hangzhou golden carp in Zhejiang.

Second, the characteristics are different.

1. German koi: The fish scales must be arranged neatly, especially the row of dark blue scales on the back of Qiucui, which must be strictly arranged neatly. Large scales often appear separately between a row of fish fillets on the back and a row of scales on the side of the abdomen, called "iron four scales", which have no ornamental value.

2. Japanese koi: With the change of age and environmental water temperature, the color and shape of the patterns on their bodies will also change, just like the special ink paintings you draw by hand.

3. The Chinese reform of the national koi: bright colors, changeable patterns, and majestic swimming style.

The essence and varieties are different, and the requirements for the environment are different.

The reason why Japanese koi is expensive is that the production rate is low, the survival rate is low, and the freight is high.

**Expensive reasons:

1. The yield rate is low in koi fish.

In the breeding process, the koi carp that really have ornamental value, especially the koi that Bu Yu can participate in the koi competition, have a very low production rate. Breeding these good-looking koi takes a lot of manpower, material and financial resources. Therefore, the koi fish in good condition are very high.

2. The elimination rate of koi is very high, an 80 cm koi carp can conceive 780,000 eggs, and about 700,000 can be discharged when ovulation, and the fertilization rate is about 80%, and the hatching rate is 80%, which can produce about four or five hundred thousand splashes.

The splash grows to 5 cm, and when the local leak is screened out after the initial screening (first selection), nearly 60% of the fry are screened, and only about 5% of the fry (about 8,000) can be left after the first selection.

These 8,000 fish.

Miao can leave 500 after the second election, 30 after the third election, and may not be able to leave one after the fourth election. In the whole process, the value of the real tung is the 500 fish fry, so the profit generated by the 500 fish.

It has to be greater than the cost of this small million fish for the fishery to survive. You said that leaving 500 fish was stressful. High-quality fish must be expensive.

3. The freight is expensive, and the pure imported koi are all from across the ocean, and the freight is very expensive.

1. The elimination rate is very high.

The amount of eggs conceived by the 80 cm koi can reach about 700,000, and the amount of eggs can be discharged at the time of ovulation is about 650,000.

With a fertilization rate of 75% and a hatching rate of 75%, the weight can produce about 10,000 splashes. The splash grows to 5 cm can be screened for the first time (a selection) to die off nearly 60% of the seedlings, after a selection can only leave about 5% of the seedlings (about 7000), the 7000 fish can be left after the second selection of 400, after the third selection can leave 20, after the fourth election may not be left. The real value in the whole process is the 400 fish, so the profit generated by these 400 fish is greater than the cost of the 699,600 fish in order for the fishery to operate.

You said that leaving 400 fish was stressful. It's strange if it's not expensive.

2. The freight of pure imported koi is expensive, and the Customs Inspection and Quarantine Bureau has not opened the import of koi, and most of the imported koi have entered the country through informal channels, so the freight is very expensive.

3. Raising koi fish is regarded as an elegant hobby, and people who can have a yard and dig a pond to raise fish are not short of money, and the market is very large and in short supply. Domestic.

To raise Japanese koi, you need to control the water temperature at 8 to 30 degrees, and ensure that the water quality is not turbid during the period, so you don't need to change the water frequently. However, when changing the water, you need to check the water temperature, and the water temperature difference is not 2 degrees. During the breeding process, Japanese koi can be fed snails, bread worms, mealworms, earthworms, vegetables and other foods.

Japanese koi fish need to be kept at a temperature of 8 to 30 degrees Celsius, and as long as the water quality is not too turbid, Japanese koi can be active under normal circumstances. Japanese koi fish are very adaptable, but very sensitive to changes in water temperature.

Therefore, when changing the water, you need to pay attention to check the water temperature first and make sure that the water temperature difference between the two is not more than 2 degrees, otherwise the Japanese koi fish will easily catch a cold. When the temperature difference exceeds 6 degrees, it will cause Japanese koi to refuse to eat and even die.

Japanese koi are omnivorous, aquatic plants, molluscs, algae, etc. can be fed, in the process of raising Japanese koi, the owner can feed them snails, bread worms, mealworms, earthworms, vegetables and other foods.
