The number of hairtail fish caught on the mainland has reached 1 million tons a year, but unfortunately, the catch of hairtail fish has been declining year by year, and even a large part of the catch has not been landed, but was hit by the waves to the shore and died naturally.
With the decrease in the catch of hairtail, people inevitably ask: "The number of hairtail fish is also decreasing, is it going to be the same as the big yellow croaker, when will it become extinct?"
There is a great similarity between the death of the hairtail fish and the extinction of the large yellow croaker, both because of human overfishing.
But this is not the original intention of humans, but the number of hairtail fish is increasing, until the fishing capacity of humans increases, and it is natural that hairtail fish become a regular guest at the table.
So why is there such a large number of hairtail fish, why is there a phenomenon that the catch is getting smaller and smaller?
Will hairtail fish become extinct like big yellow croaker?
Fishing for deep-sea fish has always been a challenge because humans are not suitable for the deep sea.
So what can humans do to change the gradual decline in the number of hairtail fish?
Deep sea fishing is difficult.
Hairtail is a deep-sea fish that has many incompatible areas with humans.
Human beings cannot survive in the vast and endless deep sea in the depths of the deep sea, and the environment of the deep sea is very harsh.
If a human sinks into the deep sea, the body will be affected by the atmospheric pressure of the deep sea, and the blood will be concentrated due to the pressure, and eventually the human will suffocate due to lack of oxygen.
The deep-sea environment is very dark, with only very little light, and the water temperature in the deep sea is extremely low, and the water temperature is close to freezing.
It is simply not enough to provide a warm environment for humans, and the creatures in the deep sea are very strange, and in order to adapt to the harsh environment of the deep sea, the creatures of the deep sea have undergone a lot of changes.
For example, deep-sea fish will have some faint fluorescence on their bodies in order to adapt to the dark environment of the deep sea, and deep-sea largemouth fish will open their mouths wide to catch falling food.
The shell of the deep-sea lobster is very hard, with a high exoskeleton strength, and other creatures in the deep sea are also strange.
The harsh environment of the deep sea is not suitable for human survival, but it does not stop humans from fishing in the deep sea.
In order to obtain the abundant food resources of the deep sea, human beings compete with deep-sea creatures.
However, the overstretched human beings were not intimidated by the harsh environment of the deep sea, but adopted various means to capture deep-sea creatures, and even developed many tools and machines to catch deep-sea creatures.
However, the environmental conditions of the deep sea are also relatively special, and many fishing tools are affected by the deep sea conditions, which will seriously reduce the fishing efficiency, and even some can be easily damaged, causing huge losses.
Therefore, the cost of deep-sea fishing is also very high, but despite this, humans still do deep-sea fishing, because deep-sea resources are still abundant, but humans have to pay a higher price.
One of them is the hairtail fish, which is still much less difficult to catch than some economically valuable fish, although it is relatively easy to catch.
Although they are less difficult to catch, they still live in the deep sea, so they are more difficult to catch than shallower fish, which is relatively speaking.
There are many reasons why deep-sea fish are difficult to fish, on the one hand, because the habitat of deep-sea fish is very closely related to the depth of the deep sea.
Many deep-sea fish live in the deep-sea area with a water depth of 200 meters ~ 4000 meters, and even some live in the sea below 4000 meters.
Hairtail fish also belong to this kind of relatively deep sea area, but they are not as deep as other deep-sea fish, they generally live in the sea area of 1000 meters ~ 3000 meters.
Therefore, their fishing is still relatively simple, on the other hand, because of the environmental conditions of the deep sea, many fishing tools will be affected by the environment, resulting in higher difficulty in fishing.
But the harsher the deep-sea environment, the more abundant the resources are, and therefore the price for humans to catch those precious foods.
So deep-sea fish fishing is very challenging, but their economic benefits are higher, so humans are willing to pay the price.
But there is still a big problem with deep-sea fish fishing.
It is the environmental conditions of deep-sea fish fishing, which requires humans to store the fish caught in a special environment after the end of fishing.
Otherwise, they will die quickly and will not be able to be eaten by humans.
The same is true for hairtails, so after the hairtail is finished, humans put the caught hairtail fish in the refrigerator and freeze it.
However, the freezing environment is only -18°C, so deep-sea fish are prone to cell death, which can lead to the death of hairtail.
Deep-sea fish fishing is generally carried out in the form of large fishing vessels, which are frozen.
The history of hairtail.
Hairtail fishing has a long history in the mainland, dating back to the Ming Dynasty, when hairtail was very widespread in the mainland.
We know that in the past, there was material poverty, and only some wealthy families could earn money to support themselves.
But those poor families can't support themselves with the money they earn on their own, so many people will borrow money from rich families.
Some even have the move of collateralizing the item.
At that time, people ate very little food, and they would use hairtail fish and cakes as staple food, and even hairtail fish would be boiled with cakes to become hairtail stewed cakes.
Moreover, the hairtail of this period can now be eaten in a vast area of China.
In the late Ming Dynasty, after Wang Shouren quelled the uprising in the Jiangxi region, he would go to that area to hunt and catch food, and the hairtail fish was a delicacy in the rich area, Wang Shouren and his army ate the hairtail, and after having the hairtail, Wang Shouren won the next battle.
His troops all said: "Blessed are the people with fish, and the places with fish are popular with everyone."
Since then, there has been a saying that hairtail fish is associated with good luck, and it is believed that eating hairtail fish can bring good luck.
However, at that time, there was another name for the hairtail in the folk called herring, and some people also called it "green ribbon", but there are ancient documents that record the name of the hairtail.
It was once recorded in the "Tang Food Chronicle": "Hairtail fish, or herring fish, is used in soup and is delicious."
It can be seen that this kind of food has been available as early as the Tang Dynasty, but it has different names in various periods.
Before the Song Dynasty, hairtail fish was a very delicious and precious food, but like yellow croaker, the number of hairtail fish gradually increased according to the changes of time and environment.
Therefore, after the Ming Dynasty, the number of hairtail fish is no longer a precious and rare food, and even ordinary families can eat hairtail.
Moreover, the reproductive ability of living organisms is very strong, and millions of offspring can be bred every year.
In particular, the hairtail fish has a strong reproductive ability, which can lay 35,000 eggs at a time, of which the hatching rate is as high as 70%, so the offspring after a single breeding has been as high as more than 8,000.
So you can see how amazing the number of hairtail fish is.
At about that time, the number of hairtail fish had reached the critical value that the marine ecological environment could bear, so if the number of hairtail fish increased at that time, it would cause ecological imbalance.
Therefore, in the face of this risk of ecological imbalance, the environment will also change, and these changes will directly affect the birth rate of hairtail fish.
Therefore, even if the reproduction ability of the creature is strong, it will affect the reproduction.
After growing up and maturing, hairtail fish often choose to return to the place where they were born to breed.
This phenomenon is known as "migratory reproduction".
The breeding cycle of the hairtail fish is one year, and it is precisely because of this special habit that when humans catch the hairtail, they choose to catch it in the autumn and winter.
Will hairtail fish become extinct?
The gradual decline in the number of hairtail fish has a lot to do with the way humans fish for fishing.
With the improvement of human fishing capacity, more and more types of deep-sea fish are being caught.
Some fish species are even endangered.
For example, if the large amount of fish is too large, its reproduction rate will not be able to keep up with the fishing speed, and eventually the extinction of the large yellow croaker.
Our human fishing capacity is getting stronger and stronger, but this is based on the fact that our human reproductive ability is getting stronger and stronger, and the number of human beings is also increasing.
We are eating more and more large yellow croaker, but we also have enough people to consume large yellow croaker.
But this is not the case with fish, which, like us humans, only choose to breed in a suitable environment.
Otherwise, even if the environment is suitable for breeding, there will be some special reasons why fish cannot reproduce.
The same happens with hairtails.
Overfishing will lead to a decrease in the number of hairtails, and since both humans and humans choose to catch in autumn and winter, overfishing will lead to a decrease in the number of hairtails, and the number of hairtails will also change abruptly.
Therefore, the harvesting humans will choose to catch other deep-sea fish next time, and wait for the number of hairtail fish to increase again before fishing.
However, if the interval between harvests is too long, the deep-sea environment will also be affected, and these changes will affect the ability of the hairtail fish to reproduce.
This results in a faster decline in the number of hairtails, so the risk of extinction is very high.
Secondly, hairtail fish, like other deep-sea creatures, have great special requirements because their habitat is in the deep sea.
Therefore, it is impossible to artificially breed hairtail fish.
Therefore, if you want to get back women to solve this problem, you must protect the living environment of the hairtail fish.
Otherwise, if the living environment of the hairtail is not protected, the hairtail fish will face the danger of extinction.
epilogue
There are many similarities between the survival requirements of hairtail fish and humans, but changes in the number of organisms are closely related to changes in the environment.
For the survival of living things, the protection of ecology is the top priority, and only by protecting the ecology can we protect and survive.
