In the absence of artificial stocking of fish fry, why do small fish appear in the newly built fish

In daily life, we will find that small fish ponds such as small fish ponds in the countryside will still appear after a long time even if there is no artificial fixed input, but the amount will be relatively small. It stands to reason that there would be no fish in the absence of importation. So, it's clear that this part of the fish that appears on its own is due to other species.

Some people believe that the reason why small fish can still appear without artificial fingerlings is that birds carry fish fry from afar into the pond.

We all know that in our daily lives, we often encounter natural phenomena such as birds preying on fish. And there is a certain inevitable connection between living things. It is believed that the fish in the pond are likely to come from this part of the small birds that prey on fish.

First of all, small fish naturally develop from fish eggs, and this part of the fish eggs is likely to be the small fish and fish eggs devoured into their stomachs when the birds are preying on the fish, and the part of the fish eggs that have not been digested, and finally this part of the fish eggs will return to the pond with the excrement of the birds.

This is the reason why small fish still appear in our daily lives, even in ponds where there are no artificial fingerlings. But at the same time, as we said at the beginning, there are very few fish in the pond in this case, because it is a very unlikely time, and we can only pass through the more tenacious and lucky fry in the undigested part of the bird's digestive system. Only then will they be able to be reborn in the following environment.

But such a thing is a small probability event after all. Therefore, it is obviously impossible to increase the number of fish in the fish pond through such a method, which is why we go to artificially breed fish. In fact, scientifically speaking, farmed fish are better than wild fish.

We all know that small fish are developed from fish eggs, well, there are small birds that will make a living from fishing, and in the process of eating small fish, they have a few tenacious fish eggs that may be returned to the water through the excrement of small birds, and the eggs can be reproduced into small fish.

I'm sure many people have encountered such a thing, that is, there are fish in the newly built fish pond. In fact, this situation is entirely due to the fact that there are fish seeds in the water, which flow into the fish pond with the current.

Although there are no artificial fry in the reservoir, when you take water from the reservoir, you may bring the eggs from the reservoir to the pond, and the eggs will grow up and become small fish!

That's because the newly built fish pond actually has fish eggs, so the eggs will hatch into small fish.

Because the eggs can survive for a long time in the case of lack of water and drought, they have the opportunity to hatch into small fish when there is water.

Fish are egg-shaped animals, and it is possible that the birds eat the fish and do not digest them, and excrete them in the fish pond to grow into fish.

There will be fish in the fish pond without fry, which may be due to the fact that the pond is not cleaned, resulting in some of the eggs still in the pond, or they enter the water body with the help of birds and insects, so as to hatch into fish. Usually in order to avoid some harmful species to the fish pond, it is necessary to clean the pond first, and the pond must be cleaned thoroughly, splashed with quicklime or bleaching powder, and the fish can be released after a week or two. <

1. Seedling: Fish pond fish farming should first be put into the seedling, choose high-quality seedling, if it is a set of breeding, you need to prepare a variety of fish fry, such as grass carp, carp, silver carp, etc. Fry need to be disinfected before restocking to prevent it from being infected with insect diseases in the future.

Normally, a batch of fry will die after the fry are released, usually due to transportation.

2. Water transfer: Fish farming must be water, especially when high-density farming, food must be sufficient. Therefore, in order to fertilize the water for a certain period of time, bacillus and photosynthetic bacteria can be used to promote the reproduction of microorganisms, so that the fry have enough food and can also inhibit the growth of harmful bacteria.

3. Feeding: After the fry grow to a certain size, they need to eat feed. Usually choose ryegrass, but not too old, otherwise it will cause enteritis, and do not throw overnight grass, the day is not eaten need to be fished out at night, so as not to be eaten by fish the next day.

Of course, it can't appear out of thin air, and scientists have discovered that some special climatic conditions have brought fish roe from other places to these places.

As long as the pond is dug up, fish from other ponds can swim over on their own. Because they are active on their own.

Because fish eggs can survive in the soil for countless years, these fish are eggs from a long time ago, and hatched after encountering water.

Fish eggs can survive for long periods of time in dehydrated environments.

It is called thousand-year-old fish roe, and where there is water, there are fish. There are several possibilities for the genus to have fish after the depression has been waterlogged for a long time.

1 There were fish in this place, and these fish would spawn before the drought came, and bury their eggs in the mud, and the broodstock would die because of the drought, but the eggs would live for a few months, and when the next rainy season came, the small fish would hatch.

2 Because of the heavy rains, the nearby fish ponds were flooded, and the fish or eggs in them were washed out and hatched or grown in the depressions.

3 Because birds or other animals go to the water's edge to fish and bring their eggs to the depression, the eggs hatch into small fish and grow in the depression. This is also one of the methods of fish transmission.

If you put a tank of water in a large tank, no matter how long it takes, small fish will not hatch.

The fish eggs were mistakenly entered, so let's see if there are any bear children nearby.

I think so.

The cause should be aquatic kun.

When the pond was first dug up, no one put fry in it, but the miraculous thing was that after a while, there were many small fish floating in the pond, and there was not a single species. Everyone was curious, so they asked the old people in the village, and some of the old people said that this was also "God's favor"; Some old people argued, haven't you read "thousands of years of fish roe, 10,000 years of grass seeds", fish eggs are very vigorous, can be stored for thousands of years under the condition of little water, once the time is ripe, small fish will be produced.

Because the flood brought back a lot of fish and shrimp, there is no doubt that a lot of fish roe has been left in the land resources, and the temperature is just enough for the fish roe to produce small fish. Once, after class, I went to swim in the pond with my friends, and when I came to the pond on the ground, I saw an old lady who believed in Buddhism in the village, carrying a packaging bag, and there were two and a half carps in it. That time also made me understand that there were still some fish in the pond that had been converted by well-meaning old people.

There are no fingerlings in the pond, so why do there be small fish for a while?

There are many reasons why the fish in the pond are raised by roe, and some people have never neglected the fish species in the pond to produce small fish. Sometimes birds have fish roe on the soles of their feet or in their stomachs and intestines when they drink water in other water sources with many fish, and birds fly here, and they fly here to drink water or poop in ponds where there are no fingerlings, and it is possible to send fish roe to this pond and then produce small fish. It is sometimes known as the "way dandelions are dispersed", and the roe is similar to dandelions, which are very gentle, and often accompanied by violent storms and rains to send them to other ponds, and then small fish appear.

In fact, the excellence of nature is sometimes reflected in the ability to build ecological chains. The presence of fish roe is only a criterion, and it is impossible to survive without adequate nutrition.

But this is usually the case in nature, once there is a water source in an area, then the rotten tea leaves or decaying animals will breed biological strains, which will affect the growth of fish species, and gradually produce a small ecological chain. This is the reason why the pond originally did not contain fingerlings, but after a period of time, small fish were produced. In addition, if you live in an area with abundant water, or live under the mountain, close to a water conservancy hub, etc., sometimes the lower ponds will carry fish fingerlings and roe due to the flow of water, and a large number of fish will grow.

Therefore, many people in the village say that if you dig a pond when you don't have money to eat, it won't be long before a lot of fish grow out for us to eat, although it is a bit exaggerated, but it is still very reasonable.

Although there are no fish in the pond, there are fish seeds in the mud or water of the pond, so small fish will be produced after a while.

This is because the eggs of fish are very viable and can be stored in such an environment, so small fish will be produced after a while.

As the water flows, it carries some fish roe, and slowly these fish roe will hatch and small fish will appear.

Because the water in the lotus pond is constantly flowing, it will be connected to the river stream, and the small fish and shrimp will keep flowing.

Experts have shown that one is the flow of water from one to another. As we all know, every river has a certain root, but the root can also branch off into several main and tributary rivers in the middle. It is probable that the roe was lost at the root of the river at that time, and with the circulation of goods between the rivers, the roe followed the area where the reservoir was dug.

Over time, this fish grows up.

There is also an all-natural food web system. In order to maintain a relatively stable cellular metabolism, various microorganisms closely bind microorganisms to organisms through a series of eat-and-eat relationships, and these organisms are closely bound to each other by nutritious diets, just as when a bird feeds on a fish fingerling, the eggs of these fish are left on the bird's body, and when he arrives at the next place, the roe is thrown into the water. So there are fish in the water.

Fish roe and fingerlings sunk at the bottom of the pond. Although the water in the pond has dried up, the bottom of the pond is still very wet, and the fish are oviparous, so the fingerlings and roe are likely to remain at the bottom of the pond, and there is some weak water to ensure their survival. Like crucian carp, most of the ponds are dry and cannot be found.

When it rains, they sometimes move to new ponds and live and breed. The person who got out of the cage found the shrimp hole, and there were several cages, some of which migrated from the river, and there might be fish and roe in them, and the fingerlings accompanied the cages to the new pond. Some of the roe are very resilient and are dispersed to new water sources based on bird excrement.

In general, no matter how dry the water in the village pond is, you will always see fish the next year. As a fish farmer, there is an opinion that the fish in the fish pond can never be caught, even if all the water in the pond is drained. The upstream and downstream fish and the exotic fish are all the origin of the fish in the pond.

It is the wonderful places like nature that allow us to catch fish from the fishing pond every year. However, there are still some ponds in the village, which have been unmanaged for a long time, and the water is stinky when covered by weeds, so there are really no fish left. Therefore, to protect the ecological environment, you can maintain their ingredients for a long time.

There are some other fish eggs that flow into the sugar, and there may be some small trash fish, but they are not found.

Although there are no fish in the pond, there are some eggs in some cases, so after a while we usually see small fish.

There are no fish in the pond at all, but after a while there are small fish, probably there are remnants of fry in the pond, they are small, the color and the soil are mixed. There will be small fish when they grow up.

The so-called heavy rain does not mean that these fish fall from the sky with the heavy rain, but that after the heavy rain, the water level of many waters will rise, so that the water in the pond or river will overflow, and in this case, many fish will flow with the current to the ponds where there are no fish. <>

Tornadoes may occur in some areas, but when a tornado comes, a lot of the pond will be swept into the eye of the storm. As the winds of the tornado weaken, some of the fish or eggs in the pneumonia will be thrown out, in which case the fish and eggs may be thrown into a pond without fish. <>

In nature, many birds have the habit of eating fish, and these birds are likely to get some fish eggs when they catch fish. Or that there are some fish that are not completely digested by the birds. After that, the birds will fly to the pond where there are no fish, or defecate on top of the pond, in which case the eggs will fall back into the new pond and the eggs will hatch after a long time.

Of course, in addition to birds, many animals may carry fish eggs to new ponds. <>

Although there is no direct connection between the pond and the pond, there are actually some springs at the bottom of the pond, and these springs, or groundwater, are actually connected together. Sometimes the eggs or fish in the pond will flow directly to the new pond through the groundwater, and because the water can be communicated, some fish will appear in the new pond after a long time. <>

In general, if there are no fish in the pond where there are no fish, the sudden appearance of fish is actually caused by the above conditions. Of these conditions, the third scenario should be the most common, or the most common.
