CATDOLL : CATDOLL: Why is Rugao suitable for goldfish breeding?

1. Why is Rugao suitable for goldfish breeding?

In fact, Rugao is not the most suitable place for goldfish breeding, but many people breed it and it has formed an industry. In addition, they have cultivated relatively excellent butterfly tail varieties and breeding techniques unknown to outsiders, which are relatively famous. In fact, in terms of climate, Fuzhou, which is currently larger in scale, is more suitable because it is not cold in winter and goldfish can grow rapidly throughout the year, making it more suitable for goldfish breeding.

2. Which three breeding bases can my country's ornamental fish farming be divided into based on region?

Li Santaizi, Anshan, Northeast China

Fangcun, Guangzhou, Guangdong

Guilin Ocean, Haikou, Hainan

There are also tropical fish from Shanghai and Tianjin, goldfish from Beijing, and goldfish from local areas, such as Rugao butterfly tail from Jiangsu, tiger head from Fuzhou, cat lion from Wuhan, red crane from Shijiazhuang, four-ball from Shanghai, panda goldfish, and water bubble from Dalian. However, there are new developments and changes in various places this year.

3. How to raise goldfish

How to raise small goldfish

The older generation of goldfish breeders have long had the experience of "raising the water first before raising the fish", which shows that the quality of water will directly affect the normal growth and development of goldfish. The purpose of changing water is to remove dirt in the water (waste, fish feces, leftover feed, stale impurities), keep the water clean, adjust the water temperature, and add oxygen to the water, which will affect the growth and development of goldfish. If you want to raise goldfish well, you must have a basic understanding of fish water:

Raw water refers to tap water or well water that has just been released and has not been exposed to the sun. Its water temperature is often quite different from the water temperature in the fish pond (tank), and it contains more chlorine. This kind of water is extremely harmful to goldfish. 2. New water is tap water, well water, or spring water that has been exposed to the sun and left to stand for about 2-3 days, and is dry and clean water that is equal to or similar to the water temperature in the fish pond (tank). 3. Old water is dirty water at the bottom of the fish pond (tank) that is rich in feces and dirt. It includes the feeding water in the pond (tank) that has not been changed for a long time. 4. Old water is a general term for clean water in the fish pond (tank) that is light green, green, old green, or green-brown. Among them, light green water is the best. There are more green algae floating in old water, which are also excellent supplementary feed for goldfish. There is less organic matter that has decayed and decomposed in this water, and more dissolved oxygen. Fish are often raised in light green and clean old water. The fish raised have the strongest appetite, strong body, beautiful color, and grow quickly. 5. Return to clear water If you find that the old green water in the original pool (tank) suddenly turns into clear water, and a lot of green algae accumulate at the bottom of the tank, this phenomenon is called return to clear water. This kind of water is easy to cause fish disease and needs to be completely replaced.

(i) Under normal circumstances, especially in the hot summer, you only need to use a hose to quietly suck out 1/10-1/5 of the feces and dirt at the bottom of the fish pond (tank) along with the stale water, remove the dust and floating feces on the water surface, and then slowly add new water of equal temperature along the wall of the pond (tank) to keep the water clean. This method of water change is not easy to hurt the fish, the method is simple and safe, and is most suitable for home fish tanks or small pond fish breeders. (ii) Some water change This water change method is mainly carried out in two situations. One situation is that in the hot summer and early autumn, the water in the fish pond (tank) has been changed for only a few days, and the water color turns green very quickly (the reason for the insufficient amount of feed), and the water quality is still clean. In order to prevent the goldfish from scalding their tails, all the goldfish in the pond (tank) can be taken out, and then the water in the pond (tank) can be turned in a spiral shape. After the pause, 1/3-1/2 of the dirt and stale water in the middle of the pond (tank) can be sucked out with a rubber tube, and then new water of equal temperature and amount can be added, and the goldfish can be taken back to the original pond (tank) for breeding. Another situation is that the water in the pond (tank) has been changed for only a few days, and the water color is still good, but because of excessive feeding on the same day, the goldfish floats, and it is necessary to adopt emergency methods. The method of changing water is the same as mentioned above. If it is a large fish pond in a fish farm, you don't need to fish out the goldfish, but use a foldable fence to surround the fish on one side, and then use the scoop net to quietly rotate the water in the pond for dozens of seconds. When the water stops, open the drain gate to gradually release the water or use a straw to suck out the excess fish worms, feces and stale water in the middle of the pond (tank), or use a scoop net to remove the excess fish worms from the middle, and then release 1/4-1/2 of the stale water, and finally write an equal amount of new water at the same temperature. This method is often used in fish farms or families when they feed too much. (3) Complete water change This water change is often combined with turning the pond (tank), selecting young fish or adult fish to change water together. It is often used when the water quality is seriously damaged or the moss is too long and the fish are too dense.

There are two specific methods: 1. If there is no spare pool, you have to scoop all the goldfish into a basin or put the net cage into the water of the adjacent pool for temporary breeding, and add oxygen to the basin or net cage. Then, brush off the moss on the wall of the original pool, rinse it thoroughly, and then refill it with isothermal new water. Let it stand for a moment until the water temperature is equal, and then scoop the fish into the original pool (tank). 2. If there is a spare pool and new water, you only need to scoop all the goldfish into a basin or net cage, and choose to handle them separately. The pools that should be divided and the pools that are not divided can be moved into the new water for breeding after the water temperature is equal. This water change method should pay special attention to the water temperature, and it is best to choose a sunny day before 9 o'clock in the morning. However, this method is generally only suitable for adult fish or larger young fish, and it is not suitable for fry. If conditions permit, before completely changing the water, you can first fill the spare pool (tank) with water, and then scoop the fish directly into the spare pool (tank). In this way, the water temperature changes little, and the fish can easily adapt to the new environment, so that the fish will not suffer from being squeezed in the basin or cage. This water change method is generally carried out once every half a month in spring and autumn. In summer, when the weather is hot and the water temperature is above 28℃, the water color is easy to darken and the water quality is easy to become turbid, the water should be completely changed once every 5-7 days. In winter, the water temperature drops to about 4℃, the goldfish move slowly, the appetite decreases, and the water quality is not easy to be damaged. Generally, the water is not completely changed unless there is a special situation.

In the south, spring is the breeding and spawning season for goldfish. They are raised in open-air places, commonly known as "out of the basin". At this time, the temperature changes greatly, goldfish are most susceptible to disease, and the mortality rate is also high. At this time, pay attention to the changes in the weather. It is necessary to cover with reed curtains at night to prevent cold, and lift the curtains during the day to expose to the sun. If goldfish overwinter under low temperature conditions, they are generally not fed. They start to be fed after being out of the basin, but it is not advisable to feed too much. Every morning, pick up the fish worms, rinse and remove the dirt, and then feed them to the goldfish. Feed less at first, and after 1 week, you can feed more. At about 3 pm every day, use a cloth bag to remove the dust and other dirt floating on the water surface, commonly known as "beating the skin". Then use a cloth bag to quietly turn the water along the fish tank and the pool for 2-3 circles. After the dirt in the water accumulates to the bottom of the tank and the pool, use a rubber hose to suck out the accumulated dirt. The amount of water absorbed is about 10% to 40% of the total amount. If the goldfish spends the winter at low temperatures, the fish body will be weaker after being taken out of the basin, so be extra careful when absorbing water. Then add an equal amount of fresh water, about 4/5 of the basin depth, to maintain a certain water temperature. The water is usually changed once every two weeks. When changing the water, first take the fish out, wash the fish basin, replace all the water with new water, and then put the fish into the basin. If the container is large, you can first release some of the dirty water, then take the fish out, wash the container, and remove the dirt. The moss accumulated on the ceramic basin or cement wall should not be completely removed. When flushing, only remove the impurities and mucus on the surface, and protect the moss bottom. Because the moss wall can generate oxygen under the action of daylight, it can also protect the surface of the fish from being scratched. The mucous membrane on the surface of the goldfish has a protective effect against the invasion of bacteria. The smooth and soft moss can also adjust the water temperature, beautify the swimming environment of the goldfish, and is conducive to the survival of the goldfish. It is normal for the water in the pool and basin to turn green. Goldfish are omnivorous and do not require much food. In addition to artificial bait, some natural baits, such as bloodworms, earthworms, shrimps, egg yolks, noodles, rice grains, bread, etc. can be used as bait. Just be careful not to pollute the water quality. It is best to feed animal bait, and the feeding should be scientific, with one guarantee and three determinations.

(I) Quality preservation: The bait must be fresh and nutritionally balanced. Do not feed the rotten and deteriorated bait. Natural bait can be disinfected with potassium permanganate and rinsed with clean water before feeding. (II) Timeliness: Feed goldfish once or twice a day. Stick to the feeding time every day and do not change the time. Generally, feed them when it is warm at noon in spring and when it is cool in the morning and evening in summer. (III) Quantity: Goldfish are relatively greedy. Feed them until they are mostly full each time. When raising fish outdoors, feed them less or not at all in shady and favorable terrain. (IV) Positioning: Choose a fixed position for each feeding. The specific choice depends on the environment. Goldfish breeding in China has a long history and is inexhaustible. As early as the Southern Song Dynasty, goldfish breeding in the palace and the palaces of dignitaries was widely popular. At that time, goldfish were only high-end pets of the royal aristocracy and could not enter the homes of ordinary people. With the development of society and the improvement of people's living standards, goldfish breeding has become widespread in thousands of households. In modern times, it has become a popular pet. According to different methods and locations, family breeding of goldfish is generally divided into three categories: courtyard breeding, balcony roof breeding and aquarium breeding. Courtyard breeding: refers to the breeding of goldfish in small ponds in villa areas and family farms, with strange stones and plants, which not only cultivates the body and mind, but also beautifies the environment and makes people feel relaxed and happy. Balcony roof breeding: Generally in Jiangsu and Zhejiang, many people use this method. Be sure to do waterproofing first to prevent pool water leakage, set up awnings to prevent the water temperature from being too high due to direct sunlight in summer, and plan a reservoir and operation channel around the breeding pond. Aquarium breeding: Generally, goldfish enthusiasts prefer to choose aquarium breeding, firstly because the price is economical and affordable, and secondly because it is easy to appreciate. If the living area at home is not spacious, placing a fish tank in the corner can add a lot of flavor to the room.
