Why are there fish in the waters of the mountains, and what animals bring them?

You may have heard the saying "a wise man raises fish in water", which means that a wise person knows how to take care of a body of water in order to receive a catch. In the countryside, if you dig a big pit and put water in it or it rains and the water flows in, then after a while, you may find that there are fish in it, but no one puts fry in it, where does that fish come from? It's amazing.

<> is not only the ponds in the countryside, but also some of the ponds in the mountains, and the fish usually do not swim up the river to the top of the mountains, and usually no one puts fish in them, so where do those come from?

Many people think that fish are born naturally, which is obviously unscientific, a life form cannot be generated so quickly, even if the organic matter in the water can form a life form, it will not directly evolve to the stage of fish. Some people also think that there are fish eggs in the soil of the pond, as the saying goes, "thousand years of grass seeds, ten thousand years of fish seeds", fish eggs can survive in the soil for a long time, this statement has a certain truth, because many fish eggs have a protective film outside, which can keep fish eggs at a certain humidity for a long time, but "ten thousand years of fish eggs" is still too exaggerated, some biologists believe that even in the right environment, the survival time of fish eggs is not more than 10 years at most.

<>So why do these newly dug ponds and pools in the mountains suddenly give birth to fish? In fact, the biggest possibility is related to water birds, we all know that water birds swim in the water all year round, then their feathers will be stained with a lot of fish eggs, but water birds can fly, some water birds are even migratory birds, their range of activity is very large, when they come to a new water area without fish, the fish eggs in the feathers will fall into the new waters, then these fish eggs hatch in the new waters, there will be fish in this water.

<>So, if there are fish in a newly dug pond or in a fishless area, if not man-made, then it is related to waterfowl.

The topography of the earth is constantly changing, and now it is a mountainous area, and it is very likely that a long time ago it was a sea, so there are fish. In addition, some birds catch fish and bring them back to the nest, and the eggs fall into the water and become fish.

The biggest possibility is related to birds, we all know that birds swim in the water all year round, then their feathers will be stained with a lot of fish eggs, but birds can fly, some water birds are even migratory birds, their range of activities is very large, when they come to a new water area without fish, the eggs in the feathers will fall into the new waters, then these eggs hatch in the new waters, there will be fish in this water.

It doesn't have to be brought by animals, either.

You must know that the grass seed of a thousand years, the fish roe of ten thousand years, which means that the fish roe can go through a long time without dying.

This is also why it is said that there are fish where there is water for a long time, that is, fish roe live for a long time. It may have been brought up by an animal, or it could have been obtained by geological changes.

Some wild animals transport fertilized eggs when they play in other pools and ditches, and then when they enter a wild pond, they fall into the pond, whereby the eggs hatch into the fish in the pond. There may also be fish in this place. Before the drought arrives, the fish deposit their eggs in the mud after spawning

When the fish is about to die, the eggs will live for several months. After the fish pond hatches. The original fish is gone.

Many people believe that fish are born. This view is obviously unscientific. Can't be so quick to live in real estate.

Even if the organic matter in the water is able to produce living organisms, it will not evolve directly to the fish stage. Some people believe that there are fish eggs on the floor of the pond. As the saying goes, "10,000 years of grass seeds, 10,000 years of fish seeds", fish eggs can survive in the soil for a long time.

This statement makes sense, as many fish eggs have a protective effect on the outside. The membrane can preserve fish eggs for a long time at a certain humidity. However, this statement is too exaggerated.

Some biologists believe that fish eggs survive the longest even in the right environment. Not more than 10 years.

So why do these fish suddenly pop up in these freshly dug ponds and ponds in the mountains? Actually,The greatest probability is related to waterfowl. We all know that waterfowl swim in the water all year round, so they will have a lot of eggs in their feathers.

However, waterfowl can fly, some are even migratory birds, and they have a wide range of activities. When they reach new water where there are no fish, the eggs in the feathers fall into the new water. After the eggs hatch in the new waters, the water will also become the basis for the survival of the fish.

We all know that the intrinsic reason for seeds to germinate is that the seed must be alive and the egg is formed through pollination and fertilization. External causes include temperature, oxygen, humidity, etc. Adequate.

Only when these conditions are met can the seeds germinate properly. Fertilized eggs are also required for the hatching of fish eggs, but water temperature, water quality, oxygen content, and bait requirements are relatively difficult. The temperature is 15-25 degrees, and the temperature is too low.

The ambient temperature of the incubation is reached, and if the temperature is too high, the internal tissues of the eggs can be easily destroyed.

The saying that where there are fish, there is water is indeed not false, and it may be that the fish in the highland waters also float from elsewhere.

I think that the fish in the alpine waters may be artificially farmed.

They all swam up from the ocean by their own efforts.

Generally speaking, they swim from some upper-class places.
