My Deep-sea Fishery

Fang Youqun took off his helmet and looked at Xiang Yang out of breath, "Brother Yang, we have fished so much now, shall we stop the meeting?"

Xiang Yang nodded, "OK."

"It just so happened that while we were resting, let's eat a few jellyfish to regain our strength."

Chen Qingsheng frowned, "Captain, are you sure this stuff can be eaten? If you remember it wrong, the consequences will be very serious."

Xiang Yang smiled and said: "If it's other jellyfish, then I really dare not pack a ticket, but if you sting a jellyfish, it is indeed edible. Although a sting jellyfish is also called a jellyfish, in fact, it should be called a jellyfish. "

Xiang Yang grabbed the sting jellyfish and said, "Although sting jellyfish are toxic and very toxic, they can be eaten with confidence as long as they are treated correctly."

In our country, the history of eating jellyfish has a long history.

As early as the Song Dynasty, some fishermen along the southern coast had learned to pickle jellyfish with coarse salt.

As long as the jellyfish is marinated with coarse salt, it will shrink and be cleaned of toxins, turning it into a delicious seafood.

Of course, this is just the easiest way to deal with it.

This method of marinating jellyfish with coarse salt is forbidden to use today.

As for the reason, it's the same as mushrooms.

There is a high probability that it is non-toxic, but a pile of marinated jellyfish, or a basket of non-toxic mushrooms, there will always be such a poisonous jellyfish or mushroom.

Generally, humans will be poisoned if they eat a bite of poisonous jellyfish or poisonous mushrooms.

From the Song Dynasty to today, there have been countless fishermen who were poisoned to death by uncured jellyfish for hundreds of years.

Moreover, jellyfish are also easily contaminated by bacteria such as halophiles, and humans are also prone to poisoning if they eat it.

Of course, if it is handled properly, eating jellyfish is also beneficial to humans.

The proper amount of edible jellyfish can not only expand human blood vessels and lower human blood pressure, but also can clean the intestines, moisten the intestines and lax, prevent constipation, and also clear the lungs and relieve coughs to remove dust in the lungs, and relieve the symptoms of coughing caused by asthma and tracheitis. The effect of.

In addition, scientists have proved through many experiments that jellyfish does have cosmetic effects.

Regular consumption of jellyfish can achieve beauty and nourishment of the skin.

If elderly people eat jellyfish, it can prevent arteriosclerosis of the human body and prolong life.

And like most seafood, jellyfish also has a certain effect on preventing human cancer.

Jellyfish can almost be said to be full of treasures.

Of course, jellyfish is a highly toxic marine creature. Even if it tastes delicious and refreshing, it has many benefits to the human body.

The benefits and disadvantages of jellyfish to humans can be said to be half and half.

In some sea areas with developed tourism, the gentle and elegant jellyfish often attract tourists' great favor and interest.

Many unknowing tourists like to go to the sea and embrace the highly poisonous jellyfish. The consequences are naturally predictable and not very beautiful.

The barbed sac of fresh jellyfish contains very intense venom, and its toxin is composed of multiple skin substances.

People who catch jellyfish or swim in the sea will be touched by the tentacles of the jellyfish, causing redness, heat and pain, epidermal necrosis, and symptoms such as body chills, irritability, chest tightness, and unbearable pain in the wound.

Xiang Yang had seen the most severely injured by a jellyfish. The person had difficulty breathing and even went into shock.

Thanks to the man who was in shock on the shore, he was not life-threatening.

If humans were to shock in the ocean, the consequences would be unimaginable.

In the midsummer of each year, it is the peak season for jellyfish growth activities, and it is also the peak time for fishermen to sting during fishing operations or when tourists swim on the beach.

There are many types of jellyfish distributed in all coastal waters of our country, and the toxins secreted by them are different in nature and harm.

However, due to the differences in individual sensitivity, people who are mildly injured by jellyfish have only general allergic reactions, and those who are severely injured can cause death.

Xiang Yang looked around and said: "From now on, everyone on our ship must learn how to effectively prevent and rescue injuries caused by jellyfish."

When Fang Youqun heard this, he immediately said with a bitter expression: "Brother Yang, this is unnecessary. I haven't been stung by a jellyfish. How can you say it is so serious?"

On the whole ship, Fang Youqun was one of the people who didn't like learning the least. When he heard Xiang Yang said he wanted to learn, he was not even afraid of jellyfish, and he immediately stood up and expressed his opposition.

Xiang Yang shook his head and said: "The venom of jellyfish can cause different degrees of damage after stinging the human body. For example, sea wasp jellyfish, the barbed wire can secrete cobra-like venom, which is the most harmful to humans. It can cause death in five minutes after the sting. ."

"For another example, after the mitral jellyfish stings the human body, it takes many days for the patient to get rid of the pain."

"You said that you have been hurt by a jellyfish before. I believe that you may have a stronger physique, but you are at sea every day. Not every jellyfish that you encounter is nothing you can do."

When Fang Youqun heard this, he immediately fell into frustration.

Fang Youqun felt scared when he heard the jellyfish that secreted cobra snake venom. He couldn't find anything to refute Xiang Yang.

Xiang Yang smiled slightly. In fact, human skin has a certain degree of resistance, not all jellyfish can sting and hurt people.

Generally, the thin and tender parts of human skin are most easily stung by jellyfish.

Take sting jellyfish for example.

If human beings are stung to the arm by a sting jellyfish, this is not a problem at all, it will be swollen and swollen for two days at most.

But if someone is stung by a sting jellyfish to the thin skin of the neck or face, the problem can be serious.

If a person stings their neck by a sting jellyfish, they will usually experience an electric shock-like tingling sensation within a few minutes.

A few hours later, the entire injured area began to gradually experience electrical tingling. Com and gradually appear linear arrangement of blood rash with erythema, itching and burning.

If the resistance is good, it may heal itself in about 20 days.

But if it has poor resistance or strong sensitivity.

After being stinged, erythema and edema, wind masses, blisters, ecchymosis, and even epidermal necrosis may even appear locally.

Generally, as long as the patients stung by jellyfish will be irritable, chills, abdominal pain, diarrhea, lack of energy and chest tightness, shortness of breath.

Many patients even have cough and wheezing, vomiting white or pink foamy sputum, accompanied by signs of anaphylactic shock such as weakness of pulse, bruising of the skin, and drop in blood pressure.

In short, if the patient is stung by a jellyfish and the rescue is not in time, the patient may die in a short time.

"If you are stung by a jellyfish, don't panic. You must tell me or Master Chen in time. As long as you are diagnosed and treated in time, you will generally get better and heal quickly." Xiang Yang said seriously, looking at everyone.
