Are crayfish native to China or imported?

With the improvement of food culture, people's clothing, food, housing and transportation have gradually changed a lot, and people's dining tables have become richer and colorful. They are beautiful, but my compatriots Guys, do you know the origin of crayfish? Are there any dangers of it? Let me tell you about it, and I will make sure your appetite will be reduced after reading it:

Crayfish was imported to China by the Japanese army during World War II. Disposal of corpses!

China did not produce crayfish in the past.

The origin of crayfish can be traced back to World War II.

The Japanese biochemical troops stationed in China had to deal with a large number of corpse,

However, considering that the energy consumption of complete incineration in a cremator is too high,

And if primary cremation is adopted and then broken down into small pieces for emission,

< p>It will cause serious eutrophication of the surrounding water bodies,

So the Japanese thought of crayfish

(the predecessor of crayfish), which could be seen everywhere in Japan at that time,

p>

After a series of genetic modifications,

Crayfish were transported in batches to the Japanese military garrison,

taking on the task of cleaning water bodies.

The improved crayfish shows

a better ability to adapt to highly corrupted water bodies than its predecessors,

stronger reproductive capacity, < /p>

Especially the ability to adapt to mineral-poisoned water bodies is even more outstanding.

Japanese declassified files show that: high nutrient,

Paragonimiasis in hypoxic water bodies Disease and black gill disease,

Crayfish carry the disease almost for life, but the mortality rate is close to normal.

As for lead, mercury, arsenic and other serious teratogenic chemical elements,

Even if the accumulation in the body of crayfish reaches several hundred times the normal value, there is no large area of ????disease in the offspring. genetic mutation.

(Experience has proved the Japanese research results.

There have been serious pollutions in rivers in various districts and counties in the south.

Even the loaches have not been able to I was lucky, but I have observed the polluted river many times and only saw one dead crayfish among the dead fish and shrimps)

Since then, the crayfish has been replaced. Crazy feeding on the incompletely cremated corpses of Chinese people

Survived in mainland China, and retreated with the surrender of the Japanese army.

The crayfish brought by the Japanese military have not faded out of mainland China.

On the contrary, the crayfish eat decaying animal carcasses.

< p>The plankton poisoned by excessive use of DDT by farmers, the excrement of various animals,

and the living things discarded by humans, gradually developed and expanded,

Finally today All over the country, in every small river with zero visibility,

in every sewage outlet of a chemical plant and septic tank,

you can see crayfish crawling slowly. , and eventually became a delicacy for Chinese people - crayfish.

After multiple verifications,

it is proved that crayfish are naturally fond of drilling holes.

The cost of breeding is too high. The retail price is generally 2.50 yuan/jin,

It has little economic value,

Farmers would rather choose low-value fish such as pond fish for 5.00 yuan/jin,

< p>I would not choose to farm crayfish,

Furthermore,

Crayfish can be found everywhere in rivers and ponds,

The cost of direct collection is much lower than that of farming .

Therefore,

I have not met any crayfish farmers.

All crayfish on the market are collected by idle farmers in local rivers and ditches. ,

The more seriously polluted the river, the more crayfish there are.

Because the river is seriously polluted and there are many crayfish,

** has become a major exporter of crayfish,

The destination is Shanghai, Shandong.

According to this,

completely destroyed the lies of some merchants who claimed that the crayfish they sold were farmed products and did not contain toxins.

Little crayfish,

Each muscle is wrapped with not just lead, mercury, manganese, chromium, arsenic,

Lungs Flukes, schistosomiasis,

The unyielding spirit and iron bones of the former Japanese soldiers are still lingering. Every gourmet who drank beer and ordered a plate of sesame seeds to satisfy his appetite,

Have you ever thought of the brutality of the Anti-Japanese War, the brutality of the Japanese army,

and the indomitable nation of the Chinese determination to resist.

Have you ever thought of Japan’s policy of comprehensive suppression and disguised plunder against our country today?

I hope that every gourmet who chews crayfish,

please think that what is in your stomach is not just beer shrimp meat,

excessive heavy metals, DDT, parasites, pathogenic bacteria,

and the unburned flesh, flesh and bones of Chinese anti-Japanese martyrs,

please use even a flash amidst the excitement of spicy food and beer-soaked desert. Thoughts of past events

Remember the heroes who sacrificed their lives back then,

And inspire us like our fearless ancestors

Use everything you have to stop Japan’s economy and diplomatic.

The truth about spicy crayfish (please don’t read it if you have tried it)

There are many people who like to eat spicy crayfish, and I am also very fond of it.

But after having a meal with a friend, who told me about its dangers,

I have never eaten that thing again. Because he is engaged in environmental protection work, he has a certain understanding of these things

It was cultivated by the Japanese,

The purpose is to use it to treat urban sewage,

< p>And is an important participant in the first processing procedure.

The dirtier the water and the higher the heavy metal content, the moister the Ma Xiaoli will live and the cleaner the water,

the faster it will die.

Later,

was introduced to China, and

Entrepreneurship Environmental Protection also used this heavy metal cleaner.

I only ate half of that meal and ended it hastily.

I firmly resist, but this year's Ma Xiao is particularly prosperous and everywhere.

It's really hard to imagine. . .

Everyone, please don’t eat crayfish.

It grows in ditches. The harsher and dirtier the growing environment is, the more vitality it has.

The more vital it is. Today’s crayfish are all artificially cultured,

But have you ever seen the crayfish culture environment?

In order to make the crayfish grow big and fat and shorten its growth period,

to satisfy the greed of the poor inland people who deceive themselves because they cannot afford seafood, < /p>

Those black-hearted shrimp farmers use large leather pipes to fill the ponds with chemical lead,

Mercury, living **, and even more, metal oil,

After the crayfish continue to absorb nutrients,

The black liquid originally exported from the leather tube

is getting cleaner and cleaner in the pond,

The more lobsters you eat, the fatter you will become.

Absolutely true.

Identification characteristics of Procambarus clarkii:

It looks like a shrimp but has a hard shell. The adult body is about 5.6~11.9cm long, dark red,

p>

The carapace is almost black, and there is a wedge-shaped stripe on the back of the abdomen.

The body of juvenile shrimp is uniform gray, sometimes with black ripples.

The chelae are long and narrow.

The middle part of the carapace is not separated by mesh-like gaps, and there are obvious particles on the carapace.

The forehead sword has side spines or the end of the forehead sword has a notch.

Biological characteristics: Crayfish adapt to the dissolved oxygen conditions of different water bodies.

The depth of its burrowing is a key factor in determining its degree of harm.

The food habits are complex and diverse. Mating occurs from late April to July, and larvae hatch after September.

The larvae are attached to the swimming legs on the abdomen of the mother, and

complete the growth and development process of the larval stage under the protection of the mother.

This method of breeding offspring ensures a high survival rate for the offspring.

Due to the strong adaptability of Procambarus clarkii,

strong resistance to stress,

wide range of food habits,

rapid population proliferation,

There is currently no effective control method for Procambarus clarkii
