Seeing Qin Xu's puzzled face, Will patted his head, he forgot that Qin Xu was purely a novice, so he introduced:

"Boss, this is the ultrasonic fish detector, which uses ultrasonic waves to send signals, and reflects back the signal after encountering a moving underwater object, and calculates the time, direction and strength of the signal response. Vertex 23us updates the fastest judgment of the underwater fish situation, and displays it on the screen through data conversion. ”

"Will, I understand these principles, what are those greens?

Qin Xu interrupted Will's explanation with a blank expression, why are you explaining this to me? I know the principle, but how does it deal with the information it feeds back? Does the green represent a group of fish?

"Okay, boss, these greens represent fish, if you look closely, they are actually small green dots, but now there are too many fish, so they are crowded together. ”

Touching the stray blonde hair in embarrassment, Will explained with a smile.

"Okay, so what are we going to do now?

Qin Xu looked at it carefully, but he didn't see the difference between one and the other in the end, so he reluctantly changed the topic.

"Well, the Internet café is already full, and it's useless to delay it any longer. And now it seems that the catch in the fishing grounds is still very rich. ”

Will nodded and suggested to Qin Xu.

"Okay, then let's go to the Internet café, I'll ask everyone to come over and help. ”

With that, Qin Xu walked out of the wheelhouse, came to the deck, beckoned Li Yang and Wang Ming, ate and drank enough, and prepared to work.

Simon found several new sets of jumpsuit jumpsuits from the cabin, the kind made of waterproof fabric. Generally, fishermen wear one when they go to sea.

"These pants are good, they are too stylish, and you didn't take them out sooner. ”

Wang Ming praised while laboriously wearing oversized water pants, and I don't know if he praised the quality of the pants or because he had the size he could wear.

"Hey, why don't we have ours, what if our clothes are dirty?"

Seeing that Simon just took a few sets of sewer pants for the men present, Su Rui protested loudly.

"You just stay on deck, you don't have to go over. ”

Qin Xu looked at this girl with black lines on her head, can she save some snacks.

"No, I can't. We're going to see it too, Yaoyao, do you say yes? ”

Su Rui didn't care about Qin Xu's objections, she pulled Xu Mengyao and began to protest, how could she not bring her for such a fun thing.

"That's it, that's it, Qin Xu, we have to go over and have a look. Sister Wu Lan, did you say yes, why didn't you take us over to see it. ”

Lin Xue, a guy who was not afraid of big things when he watched the excitement, also jumped out, and also pulled the eldest sister Da Wu Lan and protested towards Qin Xu together.

Seeing that Xu Mengyao and Wu Lan were a little moved, Qin Xu was completely helpless, women, why are they so curious?

shouted at Simon and asked him to bring over a few more sets of boot pants, one for each of the several people present.

After changing his clothes, Qin Xu led a few people towards the back deck, and after everyone stopped, Simon signaled to Will.

Seeing Simon's gesture, Will turned on the automatic winch, and with Will's operation, the automatic winch on the deck began to slowly turn, driving the trawl net and slowly retracting towards the fishing boat.

Slowly, under the gaze of Qin Xu and the others, the trawl net, which was soaked in the turquoise water, was tightened little by little, and moved closer to the deck little by little. And the white fish also loomed in the seawater.

"Damn, this is spectacular, trawlers, it's really a huge step forward in the history of human development. ”

Wang Ming looked at the big ball of all kinds of big fish, struggling desperately in the fishing net, and said with some sighs.

"Yes, it's development progress for humans, but it's a disaster for marine fish. ”

Qin Xu sighed, remembering in his mind what Will had said to him at the beginning, and said to everyone:

"You know what? Once on the West Coast, when the cod fishing season came, people could walk on their backs, and the whole sea was full of silver-white cod, and it was a spectacular sight. ”

"Isn't it?

Everyone was shocked, and Su Rui couldn't help but ask. She really couldn't imagine in her mind that the scene was so overwhelming that it was full of cod.

"It's true, I went out of my way to check the previous information. At that time, the fish in the ocean could be described as flooding. Schools of cod can be seen swimming freely in the sea.

However, since the Viking Age, when fishermen in Northern Europe began to fish for cod on a large scale, there has been no such pomp and circumstance. ”

Qin Xu's voice seemed to have a magical power, which made everyone fall silent. Every progress of mankind seems to represent the demise of other species. Our Mother Earth doesn't seem to have room for too many creatures.

Not only cod, but also a variety of marine fish that have been flooded by various samples, have also become almost extinct due to human overfishing.

Although human beings have issued various protection regulations in hindsight, how can Pandora's box, which has been opened, be closed so easily?

People are accustomed to enjoying their deliciousness, so how can they not hunt them just because they are protected? Isn't it also fun to eat these delicacies, including himself?

No buying, no killing, what a realistic saying.

"Boss, give way, the trawl is coming. ”

Simon's voice interrupted everyone's contemplation, and Qin Xu hurriedly withdrew to the side with a few people.

At this time, the trawl has been dragged to the stern, completely revealing its true face of Lushan, a long trawl is full of white flowers, and the sea fish on the arm are constantly struggling and twisting in the fishing net.

As a direct consequence of the previous overuse, the trawl mesh is now relatively large, so from time to time juvenile marine fish fall off from the huge mesh and return to the sea. In this way, we can be considered contributing to the sustainable development of the ocean.

The stern of the ship had been opened by Simon, and the automatic conveyor had already begun to operate, assisting the winch to tow the large ball of white flowers and writhing sea fish onto the fishing boat.

When all the trawls were up, Simon motioned to Will in the cab, and Will turned off the autowinch.

After setting the fishing boat on autopilot, Will jumped out of the wheelhouse and smiled with satisfaction as he looked at the mountains of fish piled up on the back deck.

"Boss, this net is probably several thousand catties, and it is basically Atlantic cod with good value, at least it has earned back the fuel cost of this trip. (To be continued.)
