CATDOLL : CATDOLL: How to breed koi?

1. How to breed koi?

1. Water quality: Koi are not very demanding on water temperature and water quality, and are suitable for living in a slightly alkaline, low hardness water environment.

2. Water temperature: The water temperature range for Koi is 2℃-30℃, and the most suitable water temperature is 20℃-25℃. In this temperature of water, Koi swim actively, have a strong appetite, are strong, and have bright colors. Because they are raised in an aquarium, the temperature can be controlled within the range of 20℃-25℃ all year round, so that Koi can have a comfortable environment and grow rapidly.

3. Quantity: For general stocking density in fish ponds, please refer to the density table for stocking koi in fish ponds; for general density in aquariums, 60 cubic centimeters × 30 cubic centimeters × 15 cubic centimeters can support 6 koi with a body length of 15 to 20 cm; 90 cubic centimeters × 30 cubic centimeters × 50 cubic centimeters can support 8 koi; and 110 cubic centimeters × 30 cubic centimeters × 50 cubic centimeters can support 10 koi.

4. Food: Koi is an omnivorous fish. It can eat mollusks, higher aquatic plant fragments, benthic animals, and even tiny algae or artificial granular bait. In other aspects, raising koi in an aquarium is similar to raising goldfish. It can be fed twice a day. The amount of feeding can be increased or decreased according to the temperature in different seasons of the year. Generally, fish worms, granular feed, small earthworms and other baits can be fed. However, it should be noted that during the feeding process, do not feed them too much. Generally, 80% full is enough. Too much will easily pollute the water quality and cause various diseases.

2. Do you have any personal opinions on breeding koi?

A good pond breeds good fish. There is no fixed specification for the size of a pond. A pond with an area of ​​one square meter can also be used for breeding. For the convenience of management, an area of ​​15 to 35 square meters is ideal, but for carp lovers, they want to watch the bold swimming posture of koi. Of course, the larger the pond, the better. The walls of the pond should be smooth, and try to avoid unevenness. The surface of the pond should be wider. If you don't want to be too particular about the landscape of the courtyard, a square pond is more convenient to manage. The location of the pond is best close to the house, because it is convenient to watch and feed in the morning and evening, and there are more opportunities for contact, which makes it easier to tame. The water depth is ideally 0.8 to 1.3 meters, and at least 60 cm. Shallow water is easily affected by ultraviolet rays in the sun, which often causes the red pigment to fade, and it is not easy to grow into a huge koi. The water surface and the edge of the pond must be kept at a distance of more than 25 cm to prevent the koi from jumping out of the pond. In order to completely prevent leakage and prevent the pool alkali from harming the fish, the walls of the new pond should be painted with plastic paint, which not only looks good but also makes it easy for moss to grow.

3. What is the history of Koi breeding?

Koi is a variant of carp, with bright colors like brocade, including red, gold, yellow, purple, blue, black, etc., and the patterns are varied. It is a large ornamental fish. According to literature records, the ancestor of koi is the common edible carp we often see, and the original species is red carp. The carp in Japan was also introduced from China. From 1804 to 1829 AD, Japanese nobles moved this colorful carp into the pond in the courtyard for appreciation. Therefore, koi is also called "noble fish". According to the characteristics of carp's easy variation, many new varieties have been bred by hybridization, cultivation and artificial selection. In 1906, the scaleless leather carp and mirror carp with three rows of scales introduced from Germany were hybridized with the original koi in Japan, and finally colorful and diverse koi were bred. Therefore, koi is a living work of art created by the Japanese. In the early 1960s, Japanese friends sent koi to garden units in Beijing, Shanghai, Hangzhou and other places for breeding several times, so that koi returned to their hometown and settled. Therefore, koi breeding farms have been established in many places. At present, koi have been released into ponds in many parks in my country for tourists to enjoy.

4. What are the prospects for breeding koi?

There is a saying in China since ancient times that "the carp jumps over the dragon gate", which means that a person will have a prosperous career and rise to prominence. In fact, in the early days, koi was only an ornamental fish for the royal family, nobles and high-ranking officials. Later, koi became popular among the people and people regarded it as a symbol of good luck and happiness. In ancient China, koi were usually kept in the ponds of officials and wealthy people.

The three colors at that time were black, white, and red with scattered patterns, which was different from the Taisho Sansho of today. That is, the Taisho Sansho of today is characterized by bright black and red spots on the white ground, and black stripes on each fin. These koi were widely introduced to various parts of Japan in March of the Taisho Sansho (1914). At this time, 27 famous carps were exhibited at the Taisho Exposition held in Ueno Park, Tokyo, Japan. The charm of such a gorgeous appearance led to the popularization of variant carps or flower carps. That is, the carp produced by the head of Higasawa Village and the carp farmers in Takezawa Village was awarded the second grade of the president's Daidoweigong and the silver medal by His Royal Highness Prince Zairen. Among them, seven of them are famous and glorious in the Kujyujinen (Imperial Palace).

If you believe in it, koi may also bring you good luck. In Feng Shui, koi also has a certain status.

If nothing else, raising koi is at least a symbol of status.

In the early Meiji period, there were already red and white, yellow, etc., and in the Taisho period, there were six types of black and white spots (white), black and yellow spots (yellow), Abe carp, Taisho three colors, three colors and red and white. The black and white spot excellent parent carp was owned by Kazuo Minemura of Ota Village. Both male and female were worth 3,000 yen. Because the era was the end of the Taisho period, it can be seen that koi seemed to have been very valuable since ancient times. By the way, the price of koi at that time was determined by the appearance of the spots. It was not uncommon for a bundle (100 fish) of 14 to 15 days old and 5 or 6 minutes long to be sold for about 10 yen.

Later, German carp and light carp were introduced, and new species appeared one after another under continuous research. In the Showa era, Showa Sanshoku, various silver scales, and golden carp appeared, and then gorgeous varieties such as Jinshui, Jin Showa, and Yamato Nishiki were produced, which continue to this day.

Today, enthusiasts and experts from all over the world are constantly improving koi varieties. It can be seen that the koi market has gradually become international. Breeding koi has gradually become a trend, and it will soon spread to the whole world.

Koi appeared around the Bunka Bunsei period, about 160 years ago. Koi breeding not only allows fish farmers to enjoy the fun of breeding and appreciating, but also can preserve and increase the value of the fish. The prospects of Koi breeding are also an important issue that fish lovers are concerned about.

Koi has bright colors, varied patterns, a healthy physique, and a majestic swimming posture. It is known as "swimming works of art" and "living gems in the water". It is a high-end ornamental fish that is popular in the world today. Ornamental koi really started in China and flourished in Japan. Japan's marketing and variety promotion are worth learning from. With the continuous improvement of koi quality and breeding technology, especially in the past two or three decades, many koi clubs have been established around the world to hold various koi tasting meetings, which has promoted the exchange and development of koi around the world, and the breeding trend is in the ascendant.

Therefore, in addition to being available for personal appreciation, the current market for buying and selling koi is also very good. There are much fewer risks than farming edible fish.
