My Deep-sea Fishery

Fang Youqun took off his helmet and looked at Xiang Yang out of breath, "Brother Yang, we've already caught so much, shall we take a break?"

Xiang Yang nodded, "OK."

"It's just right, while we're resting, let's eat a few jellyfish to restore our strength."

Chen Qingsheng frowned, "Captain, are you sure this thing is edible? If you remember it wrong, the consequences will be very serious."

Xiang Yang smiled and said, "If it's any other jellyfish, then I can't guarantee it, but the stinging jellyfish is indeed edible. Although the stinging jellyfish is also called a jellyfish, in fact, it should be called a jellyfish. "

Xiang Yang picked up the stinging jellyfish and said, "Although the stinging jellyfish is poisonous and very poisonous, as long as it is handled correctly, it can be eaten with confidence."

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

As early as the Song Dynasty, fishermen in 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 the toxins will be removed, and it will become a delicious seafood.

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

This method of pickling jellyfish with coarse salt is already banned.

As for the reason, just like mushrooms.

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

Usually, humans will be poisoned as long as they eat a bite of poisonous jellyfish or poisonous mushrooms.

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

Moreover, jellyfish are also easily contaminated by bacteria such as halophilic bacteria, and humans are also prone to poisoning if eaten.

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

Eating jellyfish in moderation can not only dilate human blood vessels and lower blood pressure, but also clean the intestines, lax the bowels, prevent constipation, clear the lungs and relieve coughs, remove dust in the lungs, and relieve cough symptoms caused by asthma and bronchitis effect.

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

Regular consumption of jellyfish can achieve the effect of beautifying and nourishing the skin.

If the elderly eat jellyfish, it can prevent arteriosclerosis 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 poisonous marine creature. Even if it tastes delicious and has many benefits to the human body, it can only be eaten in moderation and not in excess.

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

In some sea areas where tourism is developed, the soft and elegant jellyfish often arouses great interest and interest from tourists.

Many uninformed tourists like to go into the sea to embrace the highly poisonous jellyfish, and the consequences are naturally predictable and not very good.

The nematocyst of fresh jellyfish contains very violent venom, and its toxin is composed of various skin substances.

People who catch jellyfish or swim in the sea will be bruised when they come into contact with the tentacles of jellyfish, causing redness, swelling, heat, pain, skin necrosis, and symptoms such as chills, irritability, chest tightness, and unbearable pain in the wound.

Xiang Yang had seen the most serious jellyfish sting. That person had difficulty breathing and even went into shock.

It was also thanks to the fact that the man went into shock on the shore and did not endanger his life.

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

Midsummer is the peak season for jellyfish growth activities, and it is also the peak period for the incidence of jellyfish stings when fishermen are fishing or tourists are swimming in the sea.

There are many types of jellyfish distributed in various sea areas along the coast of my country, and the nature and harm of the toxins they secrete are different.

However, due to differences in the sensitivity of individual people, the mild ones only have general allergic reactions after jellyfish stings, and the severe ones can cause death.

Xiang Yang looked around and said, "In the future, everyone on board must learn how to effectively prevent, rescue and treat injuries from jellyfish stings."

When Fang Youqun heard this, he immediately said with a bitter face: "Brother Yang, this is unnecessary, isn't it true that I have never been stung by a jellyfish before? How can it be as serious as you said?"

On the whole ship, Fang Youqun was one of the people who didn't like to study the least. As soon as he heard Xiang Yang said that he wanted to study, he was not even afraid of jellyfish, and immediately stood up to express 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, the sting of the sea wasp jellyfish can secrete cobra-like venom, which is the most harmful to humans. It can cause death within five minutes of stinging. .”

"For another example, after a man-of-war jellyfish stings a human body, it takes many days for the patient to recover from the pain."

"You said that you have been stung by a jellyfish before and you are fine. I believe that you may have a stronger physique, but you are at sea every day. Not every jellyfish you encounter has nothing to do with you."

When Fang Youqun heard this, he immediately became dejected.

The jellyfish that can secrete cobra snake venom, Fang Youqun felt scared when he heard it, and he couldn't find anything to refute Xiang Yang.

Xiang Yang smiled slightly. In fact, human skin has a certain resistance. Not all jellyfish can sting people.

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

Take the stinging jellyfish.

If a human being is stung by a stinging jellyfish on the arm, it is not a problem at all, it will be red and swollen for two days at most.

But if someone is stung by a stinging jellyfish to the neck or the face and other thin skin, it will be a big deal.

If a person is stung in the neck by a stinging jellyfish, they will generally experience an electric shock-like sting within a few minutes.

A few hours later, the entire injured area began to gradually have a tingling sensation like electric wires, and a linear blood rash with erythema gradually appeared, which was itchy and burning.

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

But if the resistance is poor, or the sensitivity is strong.

After being stung, erythema, edema, wheal, blisters, ecchymosis, and even epidermal necrosis may appear locally.

Generally, as long as the patients who are stung by jellyfish will show irritability, chills, abdominal pain, diarrhea, lack of energy and chest tightness and shortness of breath.

Many patients even have coughing and wheezing attacks, spit white or pink frothy sputum, accompanied by signs of anaphylactic shock such as weak pulse, cyanosis of the skin, and drop in blood pressure.

In short, if the patient is stung by a jellyfish and the rescue is not timely, 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 can usually get better and recover quickly." Xiang Yang looked at the crowd and said quite seriously.
