Why is the baby fish farmed everywhere still on the verge of extinction?

Baby fish are raised everywhere.

But the reason for facing endangered extinction is that in order to make money, people have reduced some wild baby fish, all of which are domestic, and because the reproductive isolation of each region is different, they are all mixed together, and the released ones will occupy the wild living space.

At the beginning of the 21st century, the country opened up the artificial domestication and breeding of salamanders, and the strong driving force to make money did make the number of artificially farmed salamanders increase, however, due to the wild salamanders.

The breed is excellent and the reproductive ability is strong, and many farmers do not hesitate to buy wild salamander, but it further leads to the reduction of the number of wild salamander.

On the one hand, as I mentioned earlier, although there are many artificial salamanders, there are very few wild salamanders. On the surface, there are a large number of captive-bred salamanders, but in fact, these raised salamanders are just a pitiful number of genes that are being duplicated.

The salamander is one of the animals with the worst migration ability, because the habitat is separated by mountain streams, lakes and rivers, the salamander has been geographically isolated in various places, and the genetic differences are getting bigger and bigger.

Due to the limited parental resources, although there are many baby fish, they are only the offspring of those few baby fish fingerlings, which does not help the population improvement of the whole baby fish. Even, captive-bred salamanders circulate across the country, and then, for the sake of protecting species, many more will be released into the wild every year, which may squeeze and threaten the living space of the local wild salamanders where they are released.

Therefore, many people think that there is more than one species of salamander in China, and there should be multiple species, but in reality, we generally classify them into one category, which is actually very detrimental to our protection of salamander.

In general, our current conservation measures are aimed at the mass reproduction of one species, while ignoring the habitat of other species. After the large number of domestic salamander species reproduces, other species will be suppressed, and then because of reproductive isolation, other species and wild salamanders are becoming more and more endangered.

Because farmed salamander and wild salamander are two different concepts. If the farmed salamanders are released into the wild, they will not survive at all. And by endangered here, we mean wild salamanders.

The "baby fish" that is farmed everywhere is still endangered, and this is because many people now raise baby fish that are not really good, and some of their breeding methods are not particularly good.

The existing number of wild salamanders is scarce, and the farmed ones are not considered wild animals, and the ecological environment is not very good for wild salamanders.

Some say that juvenile fish farming has been withdrawn from the altar. It is understood that the cost of SAL breeding has not changed much, ** has been declining. Currently, ** is below the average cost of reproduction.

Even if the market is big enough, farmers will definitely lose all their money if they ** it. However, the market has yet to recover to 4-digit per kilogram**. The era of huge profits and brutal growth in the giant SALL industry is over.

Prehistoric "baby fish."

How scary? Expert: The head is 65 centimeters, and it was once a Tyrannosaurus rex.

For food! Everyone is familiar with the baby fish, hearing its name, everyone may think that it is a soft bun, but it was not like this before, their ancestral temper can be said to be no one dares to touch it, basically no creature dares to provoke them, and at that time it also had a domineering name called the overlord salamander.

Or Cole crocodile, so how scary are prehistoric baby fish?

Through the name of it, we can understand how fierce they were at that time, and their appearance at that time was almost exactly the same as the current baby fish, they all have big heads, small eyes, and they look very cute, but they are much larger than the current baby fish, and the adult overlord salamander can generally grow up to five meters, like a car, and through the fossils they left behind, scientists.

It is inferred that their heads were about 65 centimeters in size at that time.

But what is shocking is not their size, but their diet, they lived about 200 million years ago, when dinosaurs just appeared, they still use some small animals as food, but from time to time they will also hunt some dinosaurs, even Tyrannosaurus rex is in their recipe, but it is only for cubs, to deal with an adult Tyrannosaurus rex, it is still a bit difficult for them.

However, unfortunately, through nature's selection, this strongest salamander in history eventually became extinct. The Australian continent at that time.

Separated from the continent of Antarctica and flowing northward, the climate gradually warmed as the land moved, and crocodiles began to raid Australia's rivers. At this time, Antarctica also continued to move southward, and the temperature gradually dropped, making some amphibians.

Gradually, it was unable to survive, and many creatures on the earth became extinct, and the last remnants of the overlord salamanders also died.

Through the current technology, we can roughly restore the specific appearance of the overlord salamander at that time, with a flat head and a mouth full of fangs, but I don't know what the specific cry is, and now it is often used as a character in science fiction movies or adventure short films, everyone thought that these characters were fictional at first, but now we can know that it is a real creature on our earth.

The prehistoric salamander is a ferocious sea creature, and it is similar in size to many sharks, and is able to hunt other animals many times, and is a fish at the top of the food chain.

Much larger than today's salamanders, adult salamanders can grow up to five meters, like a car, and scientists have deduced that their heads were about 65 centimeters in size at that time.

Scientists deduced that the head of the prehistoric salamander was 65 centimeters long, and the length could rise to 5 meters, even the Tyrannosaurus rex ate it.

Hello, the risks of salamander farming mainly include the following:1Disease Risk:

Baby fish are susceptible to a variety of diseases, such as white spot disease, etc., if not controlled in time, it may lead to an increase in farm mortality. 2.Water Quality Risks:

If the water quality is unqualified and unstable, it will affect the health of the salamander and even cause diseases. 3.Feed Food Risks:

There are requirements for the quality and type of feed, such as the unqualified or wrong type of citrus fruit feed, which will affect the growth and breeding effect of the baby fish. 4.Weather Risk:

Changes in air temperature and water temperature will have an impact on the growth and health of salamander, such as extreme climate and meteorological disasters will cause certain losses to salamander farming. To sum up, the risk of salamander farming is higher, farmers need to have certain breeding experience and skills, master scientific breeding technology and management methods, strengthen the health monitoring of farms, do a good job in monitoring and adjusting feed and water quality, and reasonably plan the breeding plan to reduce risks and losses.

As we all know, the salamander is a national second-class aquatic wild protected animal, when we catch the salamander in the wild, we must promptly report to the police station in the jurisdiction of the police station, if you fish or eat the salamander without permission, you will definitely suffer from the punishment of the law.

On the morning of March 7, a man in a management area of Jiangling County, Hubei Province called the police to the local police station for help, it turned out that he caught a strange-shaped animal in the main trunk canal of the four lakes, for which the man did not dare to act rashly, for fear that this is a national wild protected animal, after the local ** learned, he also urgently cooperated with the wildlife protection department to intervene in the investigation, and finally determined that the man caught a wild baby fish, which belongs to the national second-class protected animals.

The frogfish caught by the man was about 30 centimeters long and covered in gray spots. And this wild animal is obviously different from other fish, that is, it has 4 small short legs, in fact, from these appearances, this is obviously a wild baby fish. When the wildlife protection personnel carefully checked the physical condition of the salamander, did not find any abnormal damage to its body, the indicators are relatively normal, the preliminary estimate is that the salamander is likely to be a nearby aquaculture enterprise due to poor management caused it to escape, the current Jiangling County wildlife protection department plans to release the salamander for disposal.

The scientific name of the salamander is the giant salamander, which belongs to the national wild protected animals, and because its cry is like the cry of a baby, people also call it the salamander. The living habits of the salamander are mainly inhabited by the dark spring water of the Yin River under the natural environment. Due to the decline in economic value and environmental quality, the wild population of salamander is very small.

Therefore, we have to appeal that anyone who finds or captures wild animals must not deal with them privately, and must report to the police or contact the local wildlife protection department in time to let the relevant professional institutions carry out scientific disposal.

Every living thing on Earth is a very magical thing from the time it appears to the time it disappears. Human scientists have also made a lot of efforts in paleontological research. It is very important for the study of paleontology.

The Liupan Mountain giant salamander belongs to an ancient species that appeared in a very critical period of antiquity, and the evidence involves the reproduction and survival of many organisms. Therefore, from a research point of view, the giant salamander of Liupan Mountain is indeed very rare and precious, so there is no doubt that scientists take this very seriously. The value of scientific research is high.

Nature is not only the most precious aspect of Liupan Mountain baby fish.

The salamander is a very rare species. You know, the number of baby fish in the world is very rare right now. Only China has many varieties of salamander.

The salamander is not only a good aquarium fish, but also a nutritious fish. Therefore, on many levels, the value of salamanders has exceeded people's expectations, and now that the number of various giant salamanders is decreasing, the rarity is naturally increasing. As the saying goes, rare things are more expensive.

Now, as the number of salamanders is decreasing and the wild species are becoming less and less, the value of this salamander is naturally increasing. Therefore, the reason why the baby fish is precious is still the quantity. Because the quantity is relatively small, it is more worthy of being cherished.

Liupan Mountain salamander is also a very rare species among its close relatives. The number of salamanders is very small, which is the key to the ** value. At the same time, Liupan Mountain salamander is very small in the whole giant salamander species.

Therefore, this salamander plays a very important role for our biologists or the ecology of China. This salamander is also a rare species in China, and it is a very precious species from all angles. In the future, this species will definitely be protected by the state.

Therefore, with the blessing of this value, the baby fish of Liupan Mountain will naturally be very precious.

This is because the salamander is an amphibian, it generally lives in fresh water, it appeared in the same era as the dinosaurs and survives to this day, it is a relatively old species, and the number has been decreasing, so it is very precious.

The salamander is a first-class protected animal in China, and this fish has become an endangered species, and the number of existing fish is very small, so if you encounter this animal, you should immediately call the police to deal with it.

1. Only wild animals and plants with scarce numbers will be listed as protected animals and plants, and salamanders are protected animals because of the scarcity of wilds.

2. In the same way, have you ever seen chickens, ducks, geese and dogs protected by the state? It is because of the large number that it is not protected (except that people are an exception 2333333).

The growth rate of salamander is slow, the growth conditions are high, and it has high edible and medicinal value, and it has been listed as a cherished and protected animal due to ecological damage and other reasons. Now, thanks to our ecological protection, the wild salamander population has recovered.

The reason why the salamander is listed as a cherished and protected animal by ZD is because:

First, the number of survival in the wild is pitiful, and the living environment is very demanding, second, the reproductive ability is poor, the number of fertilized eggs is very low, and it is easy to die due to sudden changes in water quality and temperature, and third, there are many natural enemies, and the fry that have successfully hatched baby fish are easy to be preyed upon by the larvae of some fish-eating birds and dragonflies and other insects.

Because the salamander is a frequently endangered species, it is one of the national treasures of our country and its number is scarce, so it is designated as a rare and protected animal.

Because the salamander is on the verge of extinction, it is designated as a rare and protected animal.

Because he protects many animals, he is called a rare animal.

!The number of times is limited and cost-effective, and it's a pleasure to meet you.

Some of our rural areas are found in creeks.
