Fang Youqun took off his helmet and looked at Xiang Yang, panting. "Brother Yang, we've already caught so much. Shall we take a break?"
Xiang Yang nodded, "Okay."
"That's great. While we're resting, let's eat some 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 is any other jellyfish, I really can't guarantee it, but if it is a stinging jellyfish, it is indeed edible. Although the stinging jellyfish is also called a jellyfish, in fact, it should be called a jellyfish."
Xiang Yang picked up a stinging jellyfish and said, "Although stinging jellyfish are poisonous and very toxic, they can be eaten with confidence as long as they are handled correctly."
In our country, the history of eating jellyfish is long.
As early as the Song Dynasty, fishermen along the southern coast had learned to pickle jellyfish with coarse salt.
Once jellyfish is pickled with coarse salt, it will shrink and the toxins will be removed, turning it into a delicious seafood.
Of course, this is just the simplest way to deal with it.
Today, this method of pickling jellyfish with coarse salt is strictly prohibited.
As for the reason, it’s the same as mushrooms.
It is most likely non-toxic, but in a pile of pickled jellyfish or a basket of non-toxic mushrooms, there will always be some poisonous jellyfish or mushrooms.
Usually, humans will be poisoned if they eat a bite of poisonous jellyfish or poisonous mushrooms.
From the Song Dynasty to today, countless fishermen have been poisoned by poorly pickled jellyfish over the past few hundred years.
Moreover, jellyfish are easily contaminated by bacteria such as halophilic bacteria, and humans can easily be poisoned if they eat them.
Of course, if handled properly, eating jellyfish can be very beneficial to humans.
Eating a moderate amount of jellyfish can not only dilate human blood vessels and lower blood pressure, but also clean the intestines, moisturize the intestines and promote bowel movements, prevent constipation, and clear the lungs and relieve coughs, remove dust from the lungs, and relieve symptoms of coughing caused by asthma and bronchitis.
In addition, scientists have proved through many experiments that jellyfish does have beauty effects.
Regular consumption of jellyfish can beautify and nourish the skin.
If elderly people eat jellyfish, it can prevent arteriosclerosis and prolong life.
And like most seafood, jellyfish also has certain effects in preventing and treating human cancer.
It can be said that jellyfish is full of treasures.
Of course, jellyfish is a highly poisonous marine creature. Even though it tastes delicious and has many benefits to the human body, you should only eat it in moderation and not eat too much.
The benefits and disadvantages of jellyfish to humans can be said to be half and half.
In some sea areas with developed tourism, the soft and elegant jellyfish often arouse great favor and interest among tourists.
Many uninformed tourists like to go into the sea and embrace the highly poisonous jellyfish. The consequences are naturally imaginable and not very pleasant.
The nematocysts of fresh jellyfish contain very strong venom, which is composed of a variety of polypeptides.
People who catch jellyfish or swim in the sea will be injured by the tentacles of jellyfish, causing redness, swelling, heat and pain, epidermal necrosis, and symptoms such as chills, irritability, chest tightness, and unbearable pain in the injured area.
Xiang Yang had seen the most serious case of jellyfish sting. The person had difficulty breathing and even went into shock.
Fortunately, the man suffered shock on the shore and his life was not in danger.
If humans were to suffer a shock in the ocean, the consequences would be unimaginable.
Midsummer is the peak season for jellyfish growth and it is also the peak period when fishermen are easily stung by jellyfish while fishing or tourists are swimming at the beach.
Jellyfish are distributed in all coastal waters of my country. There are many species, and the toxins they secrete are of different natures and hazards.
However, due to differences in individual sensitivity, after being stung by a jellyfish, mild cases may only experience a general allergic reaction, while severe cases may even result in death.
Xiang Yang looked around and said, "From now on, everyone on our ship must learn how to effectively prevent and treat injuries from jellyfish stings."
When Fang Youqun heard this, he immediately said with a bitter face: "Brother Yang, this is unnecessary. It's not like I haven't been stung by a jellyfish before. How can it be as serious as you say?"
On the entire ship, Fang Youqun was one of the least studious people. As soon as he heard Xiang Yang say that he wanted to study, he was no longer afraid of jellyfish and immediately stood up to express his opposition.
Xiang Yang shook his head and said, "The venom of jellyfish can cause varying degrees of damage after stinging the human body. For example, the stinging thread of the sea wasp jellyfish can secrete cobra-like venom, which is the most harmful to humans and can cause death within five minutes of being stung."
"For example, after a Portuguese man-of-war stings a person, it takes several days for the patient to recover from the pain."
"You said you were stung by a jellyfish before and you were fine. I believe that. Maybe you have a strong physique. But you are at sea every day. Not every jellyfish you encounter will be helpless against you."
When Fang Youqun heard this, he immediately became dejected.
Fang Youqun was frightened when he heard about the jellyfish that could secrete cobra venom. He couldn't find any way to refute Xiang Yang's words.
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 susceptible to being stung by jellyfish.
Take jellyfish stings, for example.
If a human is stung by a jellyfish on the arm, it is not a big deal at all. The redness and swelling will heal in two days at most.
But if someone is stung by a jellyfish on a thin and tender skin such as the neck or face, it would be a serious matter.
If a person is stung by a jellyfish on the neck, they will usually experience a tingling sensation like an electric shock within a few minutes.
A few hours later, the entire injured area began to gradually experience an electric-like tingling sensation, and a linear rash with erythema gradually appeared, which was itchy and burning.
If you have good resistance, you may heal yourself in about 20 days.
But if the patient has poor resistance or high sensitivity.
After being stung, local erythema, edema, wheals, blisters, ecchymosis, and even epidermal necrosis may occur.
Generally, patients stung by jellyfish will show symptoms of irritability, chills, abdominal pain, diarrhea, lack of energy, and chest tightness and shortness of breath.
Many patients even experience coughing and asthma attacks, spitting out white or pink foamy sputum, and are accompanied by signs of anaphylactic shock such as weak pulse, cyanosis of the skin, and low blood pressure.
In short, if someone is stung by a jellyfish and rescue is not timely, the patient may die within a short period of time.
"If you are stung by a jellyfish, don't panic. Be sure to tell me or Master Chen in time. As long as you get timely diagnosis and treatment, you will generally get better and recover quickly." Xiang Yang looked at everyone and said seriously.
