Freshwater fish can t survive in the ocean, so where do all the fish in the river go after the Yello

Yellow River fish do not follow the Yellow River to the sea, located in the coastal Yellow River estuary, where marine fish also live, and river fish swim back before they enter the sea.

At the mouth of the river, there is a place where freshwater fish meet in the sea, and although the fish are not as developed as the human brain, when they reach the estuary and find that the environment is not suitable for their survival, they will turn back and return to the river. It is not like river sand that is aimlessly washed into the sea.

The fish in the river are still in their original places, because the fish in the river will not leave their habitat.

Fish generally swim against the current. So when the water of the Yellow River flows into the ocean, they are not washed away and go downstream. And fish have a certain adaptability to salt.

The miraculous nature has given birth to a lot of life, fish is a very common creature, its muscle fibers are very short, the water content is higher, so the meat is very delicate and the human body is easier to absorb, but also rich in nutrients, according to the growth environment of the fish, it can be divided into freshwater fish and saltwater fish, because of the two environments.

At present, inland rivers flow from higher places into low-lying estuaries and bring freshwater fish from rivers into the ocean, and marine fish generally do not actively enter freshwater. And if they do change their living environment, it can be fatal for the class. According to the law of natural selection, human beings have evolved different organism structures to adapt to the environment.

The low concentration of the liquid will seep into the high concentration of the liquid, and the salt concentration in the body of the marine fish is naturally much lower than that of the seawater, so the water in their body will be quickly lost to the seawater, or adapt to this bad situation.

Marine fish swallow seawater with a high frequency and will have relatively developed gill organs, which are used by the kidneys to filter and discharge salt, so as to achieve a state of water and salt balance. Freshwater fish, on the other hand, have a much greater salt concentration than freshwater, resulting in water entering the body of freshwater, so freshwater usually has super strong kidneys, and still continuously drains water to the outside of the body.

In a word, it is thirsty to death, and full to death. However, after entering the seawater, the water in the body will be lost too quickly, which will eventually lead to dehydration and death. It can be said that it is a tragedy that marine fish in fresh water cannot discharge water in time because the drainage system in the body cannot discharge water in time, which will also cause cell edema and die.

Naturally growing saltwater fish rarely enter freshwater, so what about poor freshwater fish, do they go down the river into the sea and die?

The instinct to survive will cause freshwater fish to flow up from the panic at the moment they are about to enter the sea, and even if they are unfortunate enough to enter the water, they will immediately notice that Yiyang is trying to swim back into the freshwater the same way, so in most cases, it is rare for freshwater fish to die as a result.

Broad-salt fish, which can survive both in salt water and freshwater, such as whitebait, swordfish, etc. Their body surface has a relatively low permeability to water and salt, which makes them better able to adapt to water with different salt concentrations and adjust the osmotic pressure of different environments. However, their greatest magic weapon is their gill organs, which contain a large number of chlorine cells to achieve a balance between water and salt.

The vast majority of freshwater fish will die, the salt content in the seawater is very high, and the cells of freshwater fish cannot adapt to this environment, and will die in the water for half an hour, or even a short time.

They can swim back and die if they come into the sea and touch the salt water.

It is very likely that the freshwater fish in the river will not be able to stand this environment and die, so they should be evacuated immediately.

In the end, they re-entered the Yellow River, and some of them flowed into some small rivers, some of which were eaten by people.

The fish may have died, or they may have been eaten by other fish. No one can say for sure.

These fish will return to the Yellow River, because it is very difficult for these fish to survive in the sea, and they will not be able to live at all, so they will definitely return to the Yellow River.

The fish that enter the sea from the Yellow River swim to some of their favorite places, and many swim to unknown places. Because the sea is very big.

In the end, it flows to various river basins, such as the Haihe River, because the animal mobility is relatively strong, and it may be eaten by people.

The living environment of large water fish and marine fish is different, so freshwater fish cannot survive in the sea, many people will have questions, a large number of fish will rush into the sea every day in the Yellow River, these fish will go **, in fact, these fish will swim to the Yellow River through their last strength.

The species of fish are also diverse, so the survival technology of fish cannot be underestimated This is a diverse type of vertebrate, and the main classification of fish is divided into two categories, one is saltwater fish, and the other is freshwater fish, so the living environment will be different. There are some similarities with humans, when people are on the plateau, they will also have altitude sickness, so it is difficult to divide in this living environment. The most common fish species are freshwater fish, and there are many freshwater fish in the Yellow River that find it difficult to adapt to life there if they are washed into the sea.

If the fish in the ocean live in freshwater, it will also be affected, and the shark will not be able to live in freshwater, so the body will become very soft and fragile, and it will be difficult to return to the original state, and many freshwater fish will also not be able to live in the sea. However, it is not possible to underestimate the survival ability of fish, although there is a difference between freshwater and saltwater, and there is more survival wisdom of fish. It can be found that large water fish generally refers to fish that can survive in salt water3, and if the salt exceeds the standard, there will be no good living environment.

First of all, let's understand freshwater fish, their gills structure is different from that of saltwater fish, the gills of fish are the same as human lungs, which is also their organ that receives oxygen and mainly filters water through a sieve sequence, and some oxygen molecules are injected into the gills.

Moreover, there will be a large amount of hemoglobin in the gills of fish, and when the three cells come into contact with water, they can feel the density of water, which is very similar to the living environment of fish. It can be found that there are some differences between freshwater and seawater, there is no high salinity of seawater, and the concentration of salt in the seawater will increase, and more water will be lost at this time, which will eventually lead to the drying up of the gill cells of freshwater fish, and eventually hypoxia, and generally these freshwater fish will swim to the freshwater area through their last strength.

As long as the freshwater fish are alive and have a little strength, even if they are constantly swept away by the raging Yellow River water and forced into the sea, they will do their best to go against the grain. It is believed that these freshwater fish also understand that the environment of the sea can threaten their lives, so they will do their best to swim back.

The water of the Yellow River is mainly freshwater, and the ocean water contains very rich elements and is also salty, so freshwater fish and marine fish are generally unable to switch environments to survive.

Eventually, these fish will find a suitable place to survive and continue to survive, and they are particularly capable of surviving.

Generally, freshwater fish living in rivers actually have a "ability", that is, "swimming against the current". The living environment of freshwater fish and marine fish is completely different, so in order to reduce the fate of freshwater fish dying due to being washed into the ocean, the fish ancestors eventually evolved in addition to a new ability, that is, "migration". Freshwater fish migrate and reproduce in rivers, and if you want them to stop migrating, there is only one way for them to die.

Some of the fish must have died, some of them became food for other fish, and some of them were swept into other places by the current.

They may be eaten by some large fish, because there are still a lot of fish in the ocean, and those fish are relatively large.

These freshwater fish do not flow into the sea with the Yellow River, and the fish continue to migrate, swimming towards the edge of death with the river, and a strong desire to survive will keep it in the area suitable for its own life.

Most of these fish go into the belly of the shark, or are eaten by other fish, or they may be converted into feed in the process, so there is also a role in this situation.

The fish choose to go to other seas, and they will choose the sea area that is more suitable for them to survive, and some fish also die.

These fish may have been eaten by some of the larger species, and it is likely that they were caught by some fishermen and used for cooking.

There are many rivers in the central region of China, and the two longest rivers are the Yangtze River and the Yellow River. We all know that the water of the river is talking about water, and the water in the sea is seawater, and the salt content is very high. Therefore, if you talk about living in the water, you will not be able to survive in the sea, and you will die because the sea is too salty.

After the Yellow River flows into the sea, what about the fish in the Yellow River?

Although the water of the Yellow River is relatively turbid and the sand content is particularly large, it does not affect the survival of fish species, and the fish resources in the Yellow River are still very rich and diverse. In particular, the carp in the Yellow River is a very valuable fish, the eyeballs are like natural pearls, and the tail and dorsal fin are also red, so it is also called "red fish", this fish has a delicious taste, comprehensive nutrition, and the corresponding price is also very high. The Yellow River has a total length of 5,464 kilometers, flows through nine provinces in China, and finally flows into the Bohai Bay.

After the Yellow River flows into Bohai Bay, all the fish in the river will go? If you follow the water of the Yellow River into the sea, won't you all die?

Actually, it's not like that, the fish don't all swim along the water, and in turn, the vast majority of fish prefer to swim upstream. Fish species have a certain range of habitats, generally they will not be far away from their habitat, even if they swim far, they will swim back, because the living environment here is more suitable for them to survive. Many species swim back to the upper and lower reaches of rivers to lay eggs after the breeding season, so that the pisces are not washed into the sea before they have yet to egg.

Some species are adaptable to the salt in the water, and if they dive into a natural environment that is not suitable for them, they will swim back home.

In addition to the estuary of the Yellow River, in fact, such a phenomenon occurs at the estuaries of the Xiangjiang River and the Pearl River. Although the current of these two rivers is not as fast as that of large rivers, there are many fish that come to the sea because of the abundant and colorful fishery resources. In addition, for the estuary of the Yellow River, because the Yellow River water contains too much sand, the river is pale yellow, while the deep sea water shows a deep blue, so it is easy to have a blue and yellow situation.

Many people come to the local area to see the characteristics of such a coastal county. In this way, driven by fishery resources and tourism resources, the local economic development can be further improved.

Fish like to swim against the current, that is, no fish will follow the current and end up in the sea. Fish have their own specific habitat, and they will not leave their habitat, so they will always stay in a certain area against the current and live here to hunt and live.

They are still in the Yellow River, they can swim against the current, and they will always live in the Yellow River basin.

There may be migration, and some fish may die in the process of entering the sea.

I think they are all dead, but they exist as decomposers in the ocean, and they can decompose all kinds of garbage in the ocean.

Freshwater fish, after entering the sea, may die and be eaten by fish in the sea; It may also live between freshwater and saltwater, and may migrate from seawater to freshwater areas. Over time, some fish are able to adapt to the average salinity of the waters.

They will swim back. Fish are very savvy, and they will swim to a suitable place for their survival.

The freshwater fish in the Yellow River cannot survive in the sea because they eventually enter the sea with the Yellow River, resulting in a lack of oxygen, some of which will decay over time, and some of which will wash ashore.

Strive against the stream.

The water of the Yellow River is very vast, but not the entire Yellow River is a galloping wild horse, the kind that can't stop it.

When the Yellow River enters the Central Plains, the river will fade from its previous roar and become softened.

It is precisely because of this that when the flow of the Yellow River slowed down, sediment was deposited in the Central Plains.
