My deep sea fishery

Xiang Yang also got serious. He was not afraid of Guang Ankang Yu, but he had to protect Professor Chen and Li Bo and Xiang Yang while facing Ankang Yu.

Regardless of the monkfish's fierce name, it is famous for its lanterns. In fact, the monkfish is fierce and can compete with the flathead brother.

The monkfish likes to hang lanterns to attract prey. Normally, when the lantern attracts the ferocious marine predators, the monkfish will hold the lantern in its mouth and escape, but when it is blocked by the marine predators, it can’t escape. , Or when food is extremely scarce, it will desperately attack enemies who are much larger than its own. It is really very ferocious, and even sharks have to detour when they see it.

"Hurry up ashore." Xiang Yang watched the monkfish swimming in this direction and hurriedly said, "If it is caught by the monkfish, it will be over."

"No."

"No way."

Professor Chen and Director Li Bo said at the same time: "We swim in the water at a speed far less than monkfish. Go up and I will stay to deal with monkfish."

Xiang Yang was almost scared by these two old men. He wanted to deal with an adult monkfish in the sea. Are you kidding me?

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

Professor Chen and Director Li Bo met after a glance, Professor Chen said, "Xiang Yang, you can go up first, let me and Director Li Bo here."

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

"What are you dragging?" Li Bodao took off the shark leather backpack on his back, and took out a silver-white flashlight-like thing from the bush. "Don't worry, we have this."

"Stun gun?" Xiang Yang blinked, "Will it hurt himself or other marine animals?"

"Don't worry, if this set of diving equipment we wear can't even block the current, it will be useless at this price." Li Bo said: "As for whether other marine life will be charged, I think we are now Not when I was talking about this."

Chen Yudao: "Basically, it will not affect other marine organisms. Although seawater can conduct electricity, the resistance of water is also very large. Basically, it is difficult to cause damage if it exceeds five meters. I don’t feel anything anymore. In addition, the stun gun equipped by our research team is a special stun gun that imitates the electric eel. Although the power is as high as 650 volts, such a strong voltage is enough to kill a cow, but the current generated during the discharge is very weak. Yes, it is generally less than 2 amperes. Although the output is direct current, the discharge frequency can reach 300 pulses per second, so each discharge time is extremely short and belongs to bioelectricity."

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

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

Professor Chen even had the mood to explain to Xiang Yang: "Then you think of me as an electric eel now, now you understand?"

The electric eel Xiangyang 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 the water, and the current is driven by resistance. The smallest path passes through, so when discharging in water, the current will pass through the water. Since the resistance of water is smaller than that of the electric eel itself, it will not be charged to itself when it is discharged.

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

Xiang Yang once watched a documentary. In a certain river, an electric eel about 1 meter long was bitten by a crocodile by the river. As a result, the electric eel was struggling to discharge, and the crocodile was electrocuted to "golden sparkle". After turning white belly to death, the electric eel himself was also electrocuted.

In the film, the crocodile did not move after biting the electric eel. The entire mouth was hung on the mud on the shore, and the body was still shaking constantly. It was obviously an electric shock. After a high voltage of hundreds of volts for more than 20 seconds, the crocodile obviously did not support it. She started to roll over and revealed her white belly. His front and back feet were stiff and he was suspected to be dead, but the other crocodiles who were in the same river with the crocodile and gathered less than ten meters in the whole process did nothing.

All in all, this stun gun can only be used in water. Wearing this diving suit to use this stun gun in the ocean will not shock you. The effective attack range of this stun gun is only ten meters and will not hurt. To other marine life, it is specially used for the researcher to defend themselves when diving.

Xiang Yang watched with enthusiasm. Relying on fishing boats to trawl fishing really depends on luck. Xiang Yang’s main way to make money is actually diving fishing.

But in fact, every time Xiang Yang led the crew to dive, he was very nervous. He was actually afraid that he would suddenly encounter some fierce marine predators during the dive. If this stun gun can be equipped on a boat, it will undoubtedly be completely To solve Xiang Yang's worries, Xiang Yang will be able to retreat even if he encounters a shark when he and his crew go into the water.

This 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 this thing can only be used underwater, and ordinary diving suits do not have insulation or resistance capabilities, so you can buy them as a collection." Li Bo said.

It may be because Xiang Yang and the others are huge, and the large number frightened the monkfish, or it may be that the monkfish stayed in the deep sea for a long time, and its eyes were degraded. Until now, Xiang Yang and the others have not been found. In short, it has been a long time. The monkfish still wandered in place and did not swim over, Xiang Yang and the others were in the mood to chat.

"Are all the diving suits on the market not equipped with a resistance function? Or is it just that our current diving suit is a custom-made, specially equipped with resistance function?" Xiang Yang asked.

"That's not enough. Insulation technology is not that difficult. Many diving equipment on the market also use resistance technology. However, this diving equipment is definitely fully wrapped. I will not say anything about fully wrapped diving equipment, just a hood. At least four digits."

Director Li Bo didn't go any further. He thought Xiang Yang would retire. After all, there were very few cases where domestic fishing boats spent tens of thousands of dollars on a set of diving equipment for a sailor.

Xiang Yang's eyes lit up.

Xiang Yang didn't know what diving equipment was used on other people's boats, but the diving equipment on his boat was fully packaged, and he could use this stun gun.
