My Deep-sea Fishery

Xiang Yang also became serious. He is not afraid of ankang fish alone, but he is a little powerless to protect Professor Chen and Li Bodao Xiang Yang while facing ankang fish.

Don't look at the monkfish's fierce reputation, it is famous for its lanterns, in fact, the monkfish is as fierce as Pingtouge.

Monkfish like to hang lanterns to attract prey. Normally, when the lantern attracts an invincible and fierce marine predator, the monkfish will take the lantern in its mouth and run away, but when it is blocked by marine predators, it cannot escape , or when food is extremely scarce, it will recklessly attack enemies that are much larger than itself. It is really fierce, and even sharks have to detour when they see it.

Go ashore quickly. Xiang Yang watched the monkfish swimming towards this direction and hurriedly said: If you get caught by the monkfish, it's really over.

cannot.

no.

Professor Chen and Doctor Li said almost at the same time: Our swimming speed in the water is far inferior to the monkfish. You go up, and I will stay and deal with the monkfish.

Xiang Yang was almost frightened by these two old men, and wanted to deal with an adult monkfish in the sea, are you kidding?

Although the monkfish species in the shallow sea may be preyed on by large fish such as sharks and groupers, the monkfish species in the deep sea can be regarded as the overlord of the deep sea. Excluding other undiscovered deep-sea predators, the monkfish has almost no natural enemies.

After Professor Chen and Director Li got acquainted, Professor Chen said, Xiang Yang, you go up first, leave it to me and Director Li.

Xiang Yang hurriedly said: If you want to go up, you will go up, and I will hold the monkfish.

What are you carrying? Director Li Bo took off the sharkskin backpack on his back, and took out a silver-white flashlight-like thing from inside, Don't worry, we have this.

Electric gun? Xiang Yang blinked, Won't it hurt yourself or other sea animals?

Don't worry, if the diving equipment we wear can't even block the electric current, it will be worthless. Li Bo said: As for whether it will shock other marine life, I think we are now Not when talking about this.

Chen Yudao: Basically, it will not affect other marine life. Although seawater can conduct electricity, the resistance of water is also very high. Basically, it is difficult to cause harm if it exceeds five meters. Basically, it will cause no harm if it exceeds 20 meters. I don’t feel anything anymore. In addition, the electric gun equipped by our scientific research team is a special electric gun made by imitating electric eels. Although the power is as high as 650 volts, such a strong voltage is enough to kill a cow, but the current generated during discharge is extremely weak Yes, generally less than 2 amps, although the output is direct current, but the discharge frequency can reach 300 pulses per second, so each discharge time is extremely short, which belongs to bioelectricity.

Xiang Yang shook his head to express that he did not understand.

Professor Chen Yu and Director Li felt a lot more relaxed after holding a stun gun.

Professor Chen was even in the mood to explain to Xiang Yang: Then you treat me like an electric eel now, do you understand now?

Xiang Yang, the electric eel, knows that the discharge organs of the electric eel are on both sides of the body. Most of its body or important organs are covered by a highly insulating structure. It is like a large battery in water, and the current is controlled by a resistor. The smallest path passes through, so when discharging in water, the current will pass through the water. Since the resistance of the water is smaller than that of the electric eel itself, it will not electrify itself when it discharges.

But if the electric eel is caught in the air, because the resistance of the air is greater than the resistance of its body, if the electric eel discharges at this time, it will shock itself. In addition, if the electric eel is injured and the insulators on both sides are damaged at the same time, When discharging, it will short-circuit like two bare wires.

Xiang Yang once watched a documentary in which an electric eel about 1 meter long was bitten by a crocodile by the river in a certain river. As a result, the electric eel struggled to discharge, and the crocodile was shocked to a golden glitter and finally directly Turning white belly to death, the electric eel was also electrocuted to death.

In the film, the crocodile did not move after biting the electric eel. Its entire mouth was hanging on the mud on the shore, and its body was still shaking. It was obviously an electric shock. After more than 20 seconds under the high voltage of hundreds of volts, the crocodile obviously couldn’t support it. He stopped, and began to turn over to reveal his white belly. His front and rear feet were stiff and he was suspected to be dead. However, the other crocodiles who were in the same river with that crocodile and less than ten meters away from each other during the whole process were fine.

In a word, this kind of stun gun can only be used in the water. Wearing this diving suit and using this stun gun in the ocean will not shock you. The effective attack range of this stun gun is only ten meters, and it will not hurt you. As for other marine life, it is specially used for self-defense when researchers dive.

Xiang Yang's eyes were burning with excitement, trawling fishing with fishing boats was really a matter of luck, and Xiang Yang's main way of making money was actually fishing by diving.

But in fact, every time Xiang Yang led the crew to dive, he was very nervous. In fact, he was also afraid of suddenly encountering some ferocious marine predators during the dive. If this kind of electric gun can be equipped on the ship, it will undoubtedly be able to completely To solve Xiang Yang's worries, in the future, when Xiang Yang leads the crew into the water, even if they encounter sharks, they will be able to retreat unscathed.

This thing is a proper diving artifact.

Xiang Yang immediately asked: Teacher, Director Li Bo, can this stun gun be sold?

Yes, it can. This thing doesn't have much technological content, but it can only be used underwater, and ordinary diving suits don't have the ability to insulate or resist. If you buy it, it will be regarded as a collectible. Li Bo guided.

It may be because Xiang Yang and the others are huge in size, and the large number of them frightened the monkfish, or it may be that the monkfish has been in the deep sea for a long time and its eyes have degenerated, and Xiang Yang and the others have not been discovered until now. In short, it has been a long time The monkfish was still lingering there and did not swim over, Xiang Yang and the others were in the mood to chat.

Don't all the diving suits on the market have the resistance function? Or is the current diving suit on our body custom-made, specially designed for Anga's resistance function? Xiang Yang asked.

Whether that's true or not, insulation technology is not difficult. Many diving equipment on the market also use resistance technology, but this kind of diving equipment must be fully wrapped. I won't say anything about fully wrapped diving equipment, just a hood At least four digits.

Li Bodao didn't go any further, he thought that Xiang Yang would retreat in the face of difficulties, after all, there were very few examples of domestic fishing boats spending tens of thousands of yuan to buy a set of diving equipment for a sailor.

Xiang Yang's eyes lit up.

Xiang Yang doesn't know what kind of diving equipment other people's boats use, but the diving equipment on his boat is fully packaged, and he can use this stun gun.
