It is not surprising that there are fish and shrimp in the pond, even if the cement pond has been built on the high mountain for a long time, and over the years there will be a lot of silt deposited on the bottom of the pond, and this silt may be the basis for the growth of small fish. In the past, I often heard the old people in the countryside say that "grass seeds for thousands of years, fish seeds for 10,000 years", that is, grass seeds will not rot after 1,000 years, and when it falls to other places with the wind, after experiencing the cultivation of soil, it will still grow grass. Fish roe is even more powerful, the roe will not rot for tens of thousands of years in the soil, and when it encounters the right environment, it will still hatch small fish.
Of course, it's impossible to know whether they are 1,0000 or 10,000 years old, but at least you can come to the conclusion that it is possible for fish roe from a long, long time ago to grow small fish, so even in a concrete pond, when the soil carries the roe to the pond by the wind, the fish suddenly "pop up".

Some freshwater fish have a protective film on the outside of their eggs and have strong vitality, and can survive for a long time without water. In this case, the bird eats or sticks to the bird, and the bird may bring the eggs in when they go to the cement pond on the mountain to drink water. In this way, the fry will be available after a while.
-
This situation is quite normal, it is very likely that the fish species brought by the flowing water, or the fish species put down by the well-wishers passing by, and the fish reproduction is particularly fast in a good environment.
-
Like some birds or other animals, drinking water in other water sources and touching the water source there, then on their feet, bodies, etc. may carry fish eggs, some species of fish eggs are more tenacious, and the attachment ability is very strong, if these birds carrying fish eggs come to the pool to drink, feet contact the water of the pool, these fish eggs may fall, so as to hatch into small fish, after a long time of rain will grow up, and then continue to reproduce.
-
Someone will go and release the animals. Some ponds, especially those with more spiritual energy, will not only have fish, but also turtles and even other rarer aquatic animals, and many people may be kind and benevolent, specially buying some fish and turtles to release. Over time, and with the addition of multiplication, there will be more and more fish in the pond.
So don't be too surprised if you see a lot of fish in the cement pool, maybe it just "fell" from the sky.
-
Dry ponds and rivers used to have fish, but if it doesn't rain for a long time, the roe and dust are mixed together, and when encountering a tornado, it is enough to carry the dust and roe into the sky and scatter it to the earth, so it is not surprising that there are fish roe in the cement pond on the high mountain.
-
Drinking water brought by birds. In nature, many birds like to drink and inhabit in water sources, so they may have a small amount of fish eggs on their bodies and feet in their feces. And the vitality of fish eggs is very tenacious.
As the old saying goes, "10000 years of grass seeds, 10,000 years of fish seeds", although this is a bit exaggerated, but there is still a reason, fish roe can survive for many years, and when it encounters the right environment, it will hatch into small fish.
-
There is an old saying in China since ancient times called "thousand-year-old grass seeds, 10,000-year-old fish seeds", which means that grass seeds can exist in nature for thousands of years without being bad, until they meet an environment suitable for their own rooting and germination, and fish seeds can exist in nature for 10,000 years without being bad, and once they encounter water, they will hatch small fish. We know that our earth is changing all the time, and the vicissitudes of life are talking about the changes in the earth's geology, and it is likely that the current mountain top is the bottom of the ocean or lake in the past, and the fish eggs left in that era have hatched small fish just when they meet the right environment.
-
There are many divergent rivers and ponds flowing into the mountain water, so there are definitely fish, which is why there are fish in the reservoirs in the mountains.
-
It is easy to "grow fish" near the reservoir, because the fish in the reservoir are in the natural cycle, and the very light eggs will fall into the surrounding puddles with the rain, and small fish will "grow" when the conditions are right.
-
Because this water flows in the pond, there will be fish eggs in the water, and after a while, the fish will hatch and there will be fish in the water.
-
I think it's because someone is free-range in it, and then slowly multiplies to a lot.
-
Some people will quietly put the fish in because of kindness or other reasons, but many people don't know it.
-
I used to have a big bucket on the roof of my house, and after a rainy season, there were fish in it.
Because the microcirculation formed by the sun on the roof of the building, the water will not be damaged.
-
Birds that eat fish may not be able to digest all the eggs in their bodies. It's normal to drain it casually.
-
There is a saying on our side that grasshoppers come out of drought and fish come out of waterlogging.

Paleontologists have been searching for the origin of life on Earth, and after several generations of efforts, we finally know that the earliest life on Earth was born in the ocean, so the ocean also has the saying that it is the cradle of life. Biologists have studied the relationship between land and marine organisms and found that almost all land organisms evolved from marine organisms, and the same is true for flying organisms. It follows that life is possible wherever there is water.
Friends who have been to the ditch to catch small fish will find that the ditch was originally dry, and after the rain, the ditch was filled with water, and then small fish appeared. Why are there small fish? Could it be that there is a secret to the origin of life hidden here?
Later, we learned that the fish in the small ditch did not grow out of nothing, but also developed from fish eggs. So where do these eggs come from? There is a saying that water flows downward, so the eggs flow with the water, and the whole process is similar to that of bee pollination.
In addition to small ditches, a similar phenomenon occurs in fish ponds in some high mountains. Water can't flow high under natural conditions, so how do the eggs from the alpine fish pond get in? The answer to this question can also be found in plants, which lack the ability to move compared to fish, but whose seeds can still spread.
In addition to insect pollination, the consumption of plants by some animals also helps them spread their seeds.
The same is true for fish, some animals can't digest the eggs after eating them, so the eggs return to nature with the feces during defecation. If you are lucky, the eggs will be able to continue to develop where there is water, which is one explanation for the presence of fish in alpine ponds. Of course, it is not excluded that the fry are artificially thrown into the pool, but in order for the fry to grow smoothly, the pool also needs to have a suitable environment, such as the right temperature and sufficient oxygen.

Because the cement floor of the high mountain water contains a lot of nutrients
-
There will be grasshoppers in the dry land for a long time, and there will be fish in the water quality for a long time, which is also a peculiar manifestation of the natural ecological chain, and the vitality of many creatures is beyond our phenomenon.
-
This is the wonder of nature, it may be that something that has been buried in the soil has been baptized by rain and turned into new life.
-
I think it's because of a lot of reasons, so the fish go there.
-
It may be that some of the fry that fell into the pond from elsewhere grew long, and after a long time, they became fish.
-
This is because there is such a magical side under the conception of nature.
-
In fact, it is quite normal, because if there is water here, there must be living things.
-
It may be because there are fish fingerlings in the water of **, and they have grown up after a long time.

Isn't this a normal phenomenon? Isn't that how humans evolved?
Satisfied. It is a common phenomenon in the world that snow does not melt all year round in high mountains. The lower limit of perennial snow cover is the snow line, that is, the line where perennial snow begins to cover, and the snowfall above the snow line is greater than the annual melt amount, and the snowfall accumulates year by year, forming perennial snow (or 10,000-year snow cover), which then becomes granular snow and glacial ice, and develops glaciers. >>>More

For Chevrolet, not only in the SUV market, but also in the overall domestic sales last year there has been a significant downward trend, and the lack of domestic sales for many years is really a big pain in my heart. Therefore, for the launch of the explorer, Chevrolet must have high hopes, hoping to boost the increase in sales in one fell swoop. >>>More
