As long as there's water in the pond, it's not long before there are fish, and why doesn't anyone put fry in the pond, and how does this fish appear?

Why dig a pond and get fish? Where did the fish come from?

There are millennium grass seeds in our country, and the saying of 10,000-year-old fish seeds is mainly a phenomenon, and the millennium grass seeds are because people have noticed such a phenomenon, in the long-term particularly arid land, there will be small grass growing after the next rain.
And the 10,000-year-old fish roe is that in a place where there has been no water, suddenly there is water because of the rain, then in this water, it may not take long for there to be fish in it, so people think that fish roe is also a thing that can survive for a long time. There is a protective film on the outside of the fish roe, which will become smaller to protect itself when it dries up, and will hatch when there is water, and the reproductive ability of fish is very strong, and a few small fish can become thousands, so a few fish roe will survive in a few days, and they will become thousands in a few days.
1. After digging the pond, inject water from the river, so that the fish eggs in the river will flow into the pond with the river water;
2. This place was a fish pond before, although the fish have been fished, but the fish eggs can survive for a long time, so that after the appearance of water, these fish eggs will become fish, and then after continuous reproduction, so that many fish will appear;
3. Brought by birds, because birds often go to other ponds or rivers to fish, they will inadvertently bring fish eggs to depression ponds, and these eggs hatch into fish.
No matter how it came about, it won't come for no reason, it must come through some channel, and it is impossible to have fish as soon as you dig a pond.
There are some fish that are very drought tolerant. For example, things like loaches and lungfish can survive in the mud for a long time, while fish roe should survive longer due to its small size.
The water flows above ground and underground. Once there is fish water, large and small tributaries, above and below the ground, there will be a channel, and maybe the fish from the small ditch and small stream will flow into the reservoir, and the natural resources will be available.
In addition, it is said that some fish roe have a capsule-like outer membrane that can isolate the external environment and allow it to survive in the silt at the bottom of the river for a long time. Then when there is water, they can come back to life.

The improvement of the ecological environment such as dissolved oxygen of fish in newly dug fish ponds takes a long time, and the water quality is relatively turbid, which is easy to cause hypoxia death of fish.
Newly dug fish pond fish farming method:
1 A few days before the fingerlings are stocked, add the pond water to a depth of 20 cm, and apply quicklime to clean the pond to disinfect and prevent fish diseases.
2. Before stocking fish fingerlings, basal fertilizer should be re-applied, generally 1000 kg to 1500 kg of fermented human, livestock and poultry mixed fertilizer should be applied per mu of water surface, and 30 kg to 40 kg of chemical fertilizer should be applied to cultivate a large number of plankton for fish to eat.
3. Fingerlings should be stocked as follows: herbivorous fish as the mainstay, supplemented by fertilizing and omnivorous fish, and the stocking quantity should be considered according to water source conditions, aeration equipment, large water and aquaculture technology.
4 .Newly dug ponds for fish farming are generally muddy and turbid, which affects fish respiration and plankton reproduction. Quicklime is sprinkled every 10-15 days, which has a good effect of sedimenting and clean water, and also plays a role in preventing fish diseases.
The dosage is 20-30 kg of chemical water per mu of pond each time, and sprinkle the whole pond each time.
5 .Regularly disinfect and clean the fish body, bait table (field), tools, etc., to eliminate pathogens and improve the disease resistance of the fish body. Once fish diseases are found, measures should be taken in time to treat the symptoms**, usually feed some leeks, garlic, onions, wild perilla, calamus, etc., can prevent and ** fish enteritis, rotten gills and parasites and other fish diseases.
6 .It takes a long time to improve the ecological environment such as dissolved oxygen of fish in newly dug fish ponds, so morning and evening inspections should be strengthened and new water should be injected frequently. Pond to do no weeds, no debris, no residual bait, etc., the early stage of aquaculture water environment is poor, the later fish carrying capacity is large, in the rainy or hot weather, easy to float head or even flood pond dead fish, should take measures to eliminate as soon as possible.

Or maybe the water quality is not good!

Why dig a pond and get fish? Are these fish from **? Birds, humans, and the wind can all inadvertently bring fish eggs, and nature is amazing.
Yes, it may take a few years for fish to slowly get fish now, but 20 years ago, my grandfather dug a 10-square, 1-meter-deep reservoir in front of our house to store water for drenching vegetables, and in less than 1 year, there were fish in it.
I was only a few years old at the time, and I wondered why no one released the fish, and there were some small fish in the tank. And the number is still very large. At that time, my family told me that wherever there is water, there will be fish.
This was also true in those days, when fish were found wherever there was water in the countryside. Even if it is not living water, as long as there is a long time in a pool of stagnant water, and when there is enough water, it is a matter of time before there are fish.
At that time, looking at the water storage tank in front of my house, the most exciting thing was the rainy day, because after the rainy day, the water in the storage tank will be full, and there will be a lot of small fish in it. Then the family used the water to pour the little vegetable garden in front of the house, and when the water was half down and there was only a little bit of water left, I could go into the pool to catch fish and play. My parents wouldn't let me come down and play in the water if the water was too full.
That's when I found catching fish to be fun.
Time is like an arrow, the sun and the moon are like a shuttle, and 20 years have passed in one fell swoop. Now this small pond in front of my hometown is still there, but it has long been overgrown with weeds, and only on rainy days there will be a little water in it. And there are no more small fish in it.
In the past 20 years, although things in front of my hometown have not changed much, the mango tree in front of my hometown has long grown from a small sapling to a towering tree, and the longan tree behind the door has long been fruitful, but it has long been without the feeling of the year. Only when I go back to my hometown to worship my ancestors during the New Year's holidays, I always think of the laughter and laughter of 20 years ago.

The first is brought by other animals. Some aquatic animals, such as cormorants, water striders and frogs, may carry their eggs to other places when they move in different water bodies. If the environment is suitable, the eggs can develop into fish on their own, so that fish will appear in the independent pond.
Second, it is possible that the free-standing pond is not truly isolated. There may be an underground river at the bottom of the pond, which is connected to other bodies of water, so that fish will swim through. In addition, when heavy rain rises and the water rises, other water bodies may be connected to the reservoir.
In this case, fish from other water bodies can easily swim over. Or the fish were washed into the pond by the flood.
-
Maybe in the process of filling the pond, you will bring some fish eggs to the canteen, so fish will grow. It may be caused by the flow of fish eggs from the river, or it may be carried by some birds.
-
This is mainly because the fish ponds you dig have a connection to the underground water source, so some of the fish flow in from the underground water source.

If it is basic farmland, it should never be repurposed. Generally, farmland can only be repurposed after approval.
Legal basis: Article 17 of the Regulations on the Protection of Basic Farmland prohibits any unit or individual from building kilns, houses, graves, digging sand, quarrying, mining, taking soil, piling up solid waste, or engaging in other activities that damage basic farmland in the basic farmland protection zone.
It is forbidden for any unit or individual to occupy basic farmland for the development of forestry and fruit industry and to dig ponds for fish farming.
Article 12 of the Land Management Law of the People's Republic of China The registration of land ownership and use rights shall be carried out in accordance with the laws and administrative regulations on the registration of immovable property.
The ownership and use rights of land registered in accordance with the law shall be protected by law, and no unit or individual shall infringe upon them.

Because this is the origin of life, and the water in the field is particularly able to provide fish growth, many fish will inhabit the field.
-
That's because there's some material in the pond that's dug up, and it's going to give birth to some fish naturally, and it's also because there's a lot of water with some eggs.
-
This is because when you dig a fish pond, there will be water, but when there is water, all kinds of birds or swallows will come to drink the water, and the fish roe in their mouths will enter the pond, so that the fish will be produced.
-
It's because fish like this environment, so digging a pond attracts a lot of fish.
-
This is related to the water cycle, and the water in the ponds dug in the field is involved in the water cycle, so there may be fish fry in the water that are not visible to the naked eye, and after a period of time, the fry will grow into small fish.

Millennial grass seeds, 10,000-year-old fish eggs" should be easier to understand. Grass seeds and fish eggs are very vigorous. Fish eggs can survive for a long time even in immature conditions.
Once there is a suitable source of water and other suitable growing conditions, there will be small fish. Even if there is no water source and no fry** around, small fish can soon be seen in small ditches, creeks and fish ponds where there is water. Common fish are crucian carp, loach, eel and other tenacious fish.
In rural areas, you can often see burrows dug in the ground. As long as there is water all year round, there must be fish.
<> this phenomenon is normal. As long as it's living water, there may be fish. may be mixed with water sources elsewhere and therefore rain, or fish eggs or silt in aquatic plants; It may also be that the water itself is not completely cut or dried, and the raw water contains fish eggs; Or the irrigation water source has fish eggs.
In other places, the name of the yude is called dog to take a nap, square skin, white note, and so on. These obvious phenomena are caused by eggs that have not had time to hatch in the past. After the mud at the bottom of the pond**, they are incubated by water.
So, you don't have to be surprised.
Shouldn't you be very happy about this kind of celebrity? You dig fish soup to raise fish. Are you happy to keep fish and don't make a hood now?
This proves that the environment of your fish pond is very good and suitable for fish farming. You can raise fish with confidence and boldness. However, if you dig up a piece of land and fill it with tap water, I don't think there will be any fish.
If you're the latter, you need to cultivate water nutrients. It is recommended that you consult a professional fish farmer to create a fish pond environment. Or you can put some small fish in the pond and let it grow slowly.
In this way, the fish can also grow slowly.
There is a saying in the countryside that there are thousands of grass seeds and fish eggs. Although it may seem like there is nothing in the pond, after a while there will be a lot of weeds and small fish swimming around in the pond. In fact, when it rains and winds, the eggs are carried from one place to another.
The eggs spread to the pond by the wind and then hatch into small fish.

Summary. If the fish pond is dug and not put on the water, it can be disinfected and sterilized with quicklime, and the pond can be dried for about half a month at the same time;
After the water is put on, it can be disinfected and sterilized with bleaching powder or fish treasure;
You have now been in the water and released the seedlings, at this time there are fish dead, the method: occasionally individual fish die, release the water to change the water, day and night, 24 hours without stopping, three or four days later, splash or spray nanosilver. After using nano silver, do not let go of running water.
Sprinkle once every two days, three times in a row, it's basically no problem.
Why do fish die in newly dug ponds?
After digging, is there disinfection and sterilization before putting on the water, and is the pond dry?
If the fish pond is dug and not put on the water, you can use Bifeng Bisheng lime to eliminate poison and sterilization, and at the same time dry the pond for about half a month; After the water is put on, it can be disinfected and sterilized with bleaching powder or fish treasure; You have now been in the water and released the seedlings, at this time there are fish dead, the method: occasionally individual fish die, release the water to change the water, day and night, 24 hours without stopping, three or four days later, splash or spray nanosilver. After using nano silver, do not let go of running water.
Sprinkle once every two days, three times in a row, it's basically no problem.
The dosage of nano silver for the purpose of judging travel is normal for prevention: 1 liter of nano silver per thousand cubic meters of water, once a month or once a month.
During fish disease: 1 liter of nanosilver per 3,000 cubic meters of water is used for a feast. Use it once every two days, after two times the fish pond will no longer die, and the third time is to consolidate.

If you want to dig a small Yuhe mountain pond, you must first find a suitable place, usually close to the water source, so as to facilitate drainage and irrigation. The size and depth of the pond are then planned according to the farming needs, after which it can be excavated. It is better to dig the fish pond to a depth of 2-3 meters, so that the water stratification can be achieved, so that the fish can be intercultured, and the economic benefits of the late mold can be improved.
It should be noted that although the fish pond is relatively deep, the water depth can be appropriately changed, for example, in winter and summer, the water can be appropriately deeper, so as to avoid the water temperature changing with the air temperature, keep warm in winter and cool down in summer.

As we all know, Real Madrid and Manchester United are a pair of old enemies, and Real Madrid is known as the starship of the football club, and his funds are abundant enough, so when he poaches Manchester United's stars, he can pay more money to let the stars serve him without counting the price, which is the simplest truth and the most effective way.
