According to the survivability of fish, they can give birth to fish after countless years.
Evolution is forced by environmental selection and reproduction, the matter that occurs at the molecular level is a random random mutation, and evolution will occur when the advantage is generated, but it cannot be ** future environment or demand, after an object is selected in a certain state, with the change of the environment to the next generation is eliminated, some organisms will be selected by the advantage of survival and finally survived, so evolution is also a response to the conditions of the current environment, fish roe in a place without water, it is not easy to live for a few yearsIn this theory, as long as there is a place where the wind blows, it is possible that there will be small fish without artificial stocking, countless years are too long, and fish may appear in just a few years, we are still not very clear about the beginning of life, but it is certain that the process is very long, if the given conditions are countless years, anything can happen. <>
If you want to figure out this problem, you don't need to figure out the beginning of life on the earth, how long has life on the earth developed to the current state, we have various theories about the beginning of life, but the most influential is volcanic eruptions, the water molecules that appeared in the earth's oceans many years ago or other inorganic molecules, the collision between these molecules finally produced life faster, after a long period of movement and change, and finally fish organisms appeared, there are a large number of elements in the lake, and fish need such elements in their bodies, There are also lakes that can't be too calm, so that fish will appear. <>
The earliest life is fish, so the living conditions of fish should be relatively good for survival, water molecules or various molecules directly affect the appearance of fish, fish roe can live in waterless conditions for a long time, even if the water is dry, the fish is dead, the water will let the fish roe grow into a fish when it reappears, and the survival ability is very good.
-
Dig a lake, and after countless years, it is possible that it will give birth to some fish, because some fish eggs will survive in the soil for many years, and when they encounter water, they will give birth to life again, and some water birds will bring some fish eggs.
-
After digging the lake, deliberately do not stock the lake with fish. After a few years or more, fish will also appear in the lake. This phenomenon is not speculation, nor is it a strange event.
On the contrary, this phenomenon is based on sound science. Due to the strong vitality of the fish eggs and under the influence of external factors, the eggs will also travel from their native zone to other rivers and lakes.
-
It's possible. Fish roe is very adaptable, it can be carried away in the wind how a place, accidentally taken to the lake has a fish.

This is for sure, when I was a soldier in the suburbs of Fuzhou City, the vegetable field of the company is also on the back mountain, and in the recess of the mountain even dug a big fish pond, there are meters long, 40 meters wide, the fish pond is dug after half a month to buy fish fry, at that time I bought grass carp, crucian carp, carp, tilapia only, there is no other miscellaneous fish, but in the spring of the second year, even the water to catch fish, in addition to the fish bought, when the water is almost dry, we go down to the pond to catch fish, good guys, King of the Mud.
Eight, yellow eel, loach, field pheasant and so on a mess of a lot, everyone wonders that these things don't know from the **, the fish pond is on the top of the mountain, the people's village is behind the mountain, almost they can't come, of course, it is not ruled out that when buying fish, there may be some fish eggs and microorganisms of this kind of thing in the water......, so I think that a fish pond will grow after a long time, and maybe the friends in the countryside will have this kind of identity......
That's for sure. I once found this phenomenon, once, I went to the mountain to pick mushrooms, found through a forest, near the top of the mountain there is a flat land of more than ten square meters, there is a puddle in the flatland, as if it is a place for cattle to bathe, I out of curiosity, I carefully looked at the puddle, about 3 meters long, 2 meters wide, into an irregular oval, the depth of about one meter, but the depth of the water is only about 80 centimeters, and as soon as I get close to the puddle, there are fish swimming in panic, muddying the water in the pit. I judged that there must be fish in the pit, so I went back to the village and told my friend, my friend didn't believe it at first, and the two of us bet, in order to verify whether what I said was true, we brought buckets and water pipes together to this puddle at the top of the high mountain, in the woods, he took a closer look, if there were really fish, we both used the principle of siphon together, sucked out the water in the puddle, and when there was not much water, we jumped into the puddle to catch fish, there were crucian carp, carp, loach, etc., and the whole pit caught more than 3 catties of fish.
I have never understood why there are so many fish in this puddle on the top of the mountain, surrounded by trees, connected by no ditches, and the water in the pit is all spring water that has been soaked out of the soil and water accumulated on rainy days. Later, when I talked about this incident with others, some people said that it flew from the sky on a rainy day, some said that it was brought by birds and beasts, and some said that it was released by others. I still don't understand how it came about.
Tell me a wonderful thing. In the early 1980s, I served as a soldier at Jinan Airport in the Air Force. The airport is a small prairie, because the ground test of jet planes will blow out some shallow craters on the ground, unless it has just rained and there is water in the small puddles, but it dries up quickly, and there are absolutely no puddles for long.
The wonderful thing happened that after the rain, not only did the small pit contain rainwater, but there were also small fish in the water.

If there is a lake, there will definitely be fish for a long time. However, it is not the lake that grows on its own, but through other means.
-
There are no fish in the water, and even if there are fish, most of them swim from other places, and they do not appear rashly, and there are not necessarily fish where there is water.
-
It should be possible, the lake is a natural environment, there will be a lot of creatures in it, if the conditions allow, if the time is long enough, there should be fish born.
-
If the lake has a current, but it is not stagnant, most of the fish are born, because the water will carry fish eggs or other aquatic organisms, but if it is stagnant water, then no fish will be born.
-
This is unlikely, there is a high probability that the event was transferred from somewhere else, even through rain or groundwater, which is possible, otherwise there would be no fish out of thin air.
-
Isn't it more reasonable to dig a big lake and there will be fish in many years, and the fish are not fish eggs, but because of heavy rains or floods, some fish are brought here?
-
Generally, after a few years of excavation in artificial lakes, although there is no artificial release of fish in it, some fish will appear more or less automatically, this phenomenon has puzzled many people, and they don't know how these fish appear out of thin air. In fact, everything has its **, the fish in the artificial lake is the same, naturally there is a channel to have fish to come, most of this situation, in fact, because the fish eggs in other fish ponds are brought to the artificial lake by nature in various forms.
There is an old saying called "fish roe for 10,000 years" brought by birds and other animals, which means that fish eggs can survive for many years, and their vitality is very tenacious, and as long as they can get into water later, they can produce life and hatch small fish. In some artificial lakes where there are no fish, small fish hatch because some animals bring their eggs to the lake. In rivers or other fish ponds, there will be many fish eggs laid by floating fish, on the surface of the water and on plants near the water surface, at this time, if there are birds, aquatic animals, or cattle that come here to drink water, as long as they have been on the surface of the water or near the water, they may be stained with fish eggs, when these birds or other animals go to the artificial lake to drink water, these fish eggs will fall in the artificial lake, and after a while, the eggs in the artificial lake will hatch into small fish.
Since the water surface of the pond and aquatic plants are stained with fish eggs when the wind blows, it is not surprising that the fish eggs will be blown everywhere by the raging wind, and it is likely that some fish eggs will fall into the artificial lake dug by humans at this time.
In addition, when it rains heavily, ponds and rivers tend to rise and the water spreads along the land, and the eggs in the ponds and rivers will naturally drift with the water, and some of the eggs will drift into artificial lakes and hatch small fish in the lakes. The ecological environment in nature is very mysterious to interact with each other, so it is impossible to keep an artificial lake pure forever without life.
-
Some fish will grow out of thin air in the artificial lake. This is mainly the eggs brought by some waterfowl. Or maybe there are some fish eggs in the area, and after passing through the water, some small fish will grow.
-
Because there are a lot of fish eggs in the soil, fish are born out of thin air in the artificial lake. These fish hatch from eggs in the dirt.
-
Most of the water in man-made lakes is brought in from other places, and the water may contain fish eggs, which hatch slowly and then become fish.
-
Without human intervention, some amphibians, insects, etc. will bring their eggs to the lake to hatch, or lay eggs directly in the lake. Birds and other creatures also forage near the lake, bringing aquatic grass seeds from other lakes to the vicinity, keeping the oxygen levels in the lake within a certain range. If it's long enough, fish will also grow in this lake.
-
According to the survivability of fish, they can give birth to fish after countless years.
-
Theoretically, yes. Actually, no. Because if you want fish, you have to have microbes, and the lake you dig may end up as a backwater pool due to the lack of fixed microorganisms and the living water that can flow, and there will be no fish at all and it will stink.
-
Normally, yes, the water above the earth is fluid, so even if there are no fish before, you can get in some way.
-
I think it's possible that this is the case, because everything in the world is constantly changing, and there may be fish.
-
After digging a lake for countless years, it is generally not possible to give birth to fish on its own, because the lake will be disturbed by nature on the earth, and it will soon be taken over by the natural ecosystem. There are also many ways of fish in the lake, but they are all exotic ways, and they cannot be fish that evolved and born in the lake themselves.
In the past, there was an old saying about fish roe, which means that the eggs laid by fish can survive for many years. The eggs are very small and light, and can be blown away by the wind, and can also drift around with the water when it rains and the water rises, so there are actually some eggs on the ground in low-lying areas where there are many ponds and rivers. When digging a lake in these places, it is likely that there are fish eggs on the soil here, and as long as there is water in the lake, the fish eggs can hatch small fish in the water, or when it rains, a small number of fish eggs on the surrounding ground will also be washed into the lake, and the fish eggs can hatch small fish when the temperature is right, so the artificial lake will soon naturally produce fish.
Waterfowl are also a variety of birds that are often in the water, and can easily carry eggs from other places to newly dug lakes. After bathing or fishing in rivers and ponds with fish eggs, these water birds often have fish eggs on their legs and bodies, and when they fly to the newly dug lake, they will bring the fish eggs with them, so that the lake produces fish; Or these waterfowl eat fish with eggs in their stomachs somewhere else, and the eggs are not digested by the birds, and when the birds defecate in the water of the newly dug lake, the feces contain these eggs, thus prompting the emergence of fish in the lake.
In addition to animal behavior and natural factors, humans sometimes make newly dug lakes produce fish. Some people are religious, and they often have regular release behaviors, that is, they go to the market to buy some small fish, shrimp, turtles and other aquatic animals, and then go to the lake to carry out release activities, and the newly dug lake is released after the fish are produced.
-
Yes. Because there are fish eggs in the soil, after digging a lake, the fish eggs hatch into fish.
-
It's possible, as long as there is sunlight and a lot of water, a lot of plants will grow that are sown with the wind, and then maybe a lot of water birds and animals will bring some fish roe with them, so it's possible.
-
Dig a lake, and after countless years, fish will grow on its own. Because the lake will be under the influence of nature, the internal environment will gradually become suitable for the growth of fish.

Lakes are a relatively common thing in our lives, and there are many lakes in many places in our country, such as Poyang Lake, Qinghai Lake, and many man-made lakes, and these lakes have a lot of organisms in them, and there are generally a lot of fish in these creatures. Except for those experts, few of us in the general public will ask how the creatures in this place came from, so if you dig a lake, will there be fish in it? Fish evolved from fertilized eggs, and if there are no surviving fertilized eggs in a man-made lake, they will not appear on their own.
Now due to the increase of various pollution, our environment is becoming more and more serious, and there is more and more garbage in the air, resulting in our ecosystem is no longer so complete, so some people assume itIf a lake is dug up that is large enough, will a whole ecology be created? In fact, such an idea can be realized, but a complete ecology will not be established, because there are too many factors in the ecosystem, and it is not possible to form a lake by simply digging a lake. >>>More
Mountains and rivers become lively because of living beings, rivers have swimming fish and become clear, it is life that has created our thousands of vivid world, many of our ponds are very far away from rivers with fish, but after a long time there will be many small fish swimming,So if you dig a river, will it give birth to fish on its own after many years? If you dig a river, there is a high chance that small fish will appear after many yearsLet's break it down. <> >>>More

Yes, the family is originally supported by two people together. When there is only one person in this family to support, it can be very tiring. In addition to this, a woman in today's society, if not very good. She can't keep up with men in terms of salary, so she will be more tired.
