What's the best way to raise goldfish?

In the history of human civilization, Chinese goldfish has accompanied human life for more than ten centuries, and it is the earliest species in the history of ornamental fish in the world. Goldfish is easy to raise, its posture is strange, the color is gorgeous, the shape is beautiful. Fish can beautify the environment and is very popular with people. It is a unique ornamental fish in China. Today, the editor will introduce to you how to raise goldfish.

The breeding environment of goldfish

The elders of goldfish breeding had the experience of "raising fish and raising water first" a long time ago, which shows that the quality of water quality will directly affect the normal growth and development of goldfish. The purpose of changing water is to remove dirt (garbage, fish feces and remaining feed, stale impurities) in the water, keep the water clean, adjust the water temperature, and increase oxygen in the water, so as to stimulate the growth and development of goldfish. If you want to raise goldfish well, you must have a preliminary understanding of fish water:

1. Fresh water: it refers to the tap water that has just been released, which is the ideal water for fish culture. However, it should be noted that the water temperature is often quite different from that in the fish pond (tank), so it is necessary to adjust the temperature (the tap water with more chlorine in some areas also needs dechlorination treatment).

2. Chen Shui: dirty water containing feces and dirt at the bottom of the fish pond (tank). Including the feed water that has not been changed for a long time in the pond (tank).

3. Old water: a general term for the clean, tender green, old green or greenish brown water in the fish pond (tank). Among them, tender green water is the best. There are many green algae floating in the old water, and they are also a good auxiliary feed for goldfish. This kind of water has less rotten and decomposed organic matter and more dissolved oxygen. Fish are often raised in tender green and clean old water. The fish have the most exuberant appetite, strong body, bright color and rapid development.

4. Back to clear water: if it is found that the old green water in the original pool (tank) suddenly becomes clear water, many green algae precipitate the bottom of the cylinder, this phenomenon is called back to clear water. This kind of water is easy to cause fish disease and needs to be replaced completely.

The method of changing water for goldfish

1. General change of water: under normal circumstances, especially in the hot summer, as long as you stick to the faeces and dirt at the bottom of the fish pond (tank) together with the old water every day, gently suck out 1max 10mer 1ram 5 with a hose to remove the dust and faeces from the water surface, and then slowly inject isothermal new water along the tank (tank) wall to keep the water quality clean. This water exchange method is not easy to damage the fish body, the method is simple and safe, and is most suitable for fish farmers in family fish tanks or small ponds.

2. Partial water change: this water exchange method is mainly carried out in two cases.

① A situation in hot summer and early autumn, the feed water in the fish pond (tank) has been changed for only a few days, and the water color turns green very fast (due to the small amount of feed). When the water quality is still clean, in order to prevent the goldfish from burning their tails, you can fish out all the goldfish in the pond (tank), and then turn the water in the pond (tank) in a spiral, waiting to rest for a while. Suck off the dirt and old water from the center of the pond (tank) with a rubber tube, then inject isothermal, equal amount of new water, and then fish the goldfish into the original pond (tank) to raise.

Another case of ② is that the water in the pool (tank) has only been changed for a few days, and the water color is still good, but emergency measures must be taken because there is too much food on that day and there is a floating head. The method of changing water is the same as that mentioned above.

If it is a large fish pond in the fishing ground, it is not necessary to fish out the goldfish, but to surround the fish with a folding net, and then gently rotate the water in the pond with a fishing net for dozens of seconds. wait for the water to rest for a moment, then open the drainage gate to slowly release water, or use a straw to remove excess fish and insects, feces and old water in the middle of the pond (tank), or after using a fish net to remove the excess fish and insects from the center, and then remove the old water of 1gamma, 41zu2. Finally, the same amount of isothermal new water is injected, which is common in the first aid method used in fish farms or families due to excessive food intake.

3. Change the water thoroughly: this kind of water change is often combined with turning the pool (tank) and selecting young or adult fish at the same time. It is often used when the water quality is seriously deteriorated or the moss is too long and the fish is too dense. There are two specific ways:

In the case of no free pool, ① has no choice but to fish all the goldfish into the basin or put the cage into the water of the adjacent pool for temporary cultivation, and add an oxygen-increasing head to increase oxygen in the basin or cage. Then, brush off the moss on the wall of the original pool, rinse thoroughly, re-inject isothermal new water, rest for a while until the water temperature is equal, and fish into the original pond (tank).

② if there are free ponds and fresh water, as long as all the goldfish are fished into the basin or cage and selected and dealt with separately, the goldfish can be reared in the new water without waiting for the same water temperature in the separate ponds. This method of changing water should pay special attention to the water temperature, and it is best to choose a sunny day before 9: 00 in the morning. However, this method is generally only applicable to adult fish or older young fish, and larvae are not suitable for use. If conditions permit, before thoroughly changing the water, fill the spare pool (tank) with volt water, and then fish the fish directly into the spare pool (tank). In this way, the change of water temperature is small, and the school of fish can easily adapt to the new environment, so that the fish can avoid the pain of squeezing and rolling in the basin or cage. This method of changing water is generally carried out every half a month or so in spring and autumn. Summer volt weather, water temperature as high as 28 ℃, in the water color is very easy to thick color, the water quality is easy to turbidity, generally 4 Mel 7 days should be thoroughly changed water once. When the water temperature drops to about 4 ℃ in winter, the activity of goldfish is slow, the appetite is reduced, and the water quality is not easy to deteriorate.

It should be noted that due to differences in density, body size, feed, feeding habits and water quality maintenance equipment, the method of water exchange should not be too dogmatic and should be adjusted according to the water quality and the state of the fish, all of which require long-term experience in fish farming.
