My Deep-sea Fishery

"My deep-sea fishery (

"You can do this." Professor Chen Yu whispered: "Aren't you familiar with the male tiger-head sea eagle? When the female tiger-head sea eagle goes out, you climb onto the cabin and install the camera. "

Xiang Yang blinked, "Okay, leave this to me."

In fact, Xiang Yang never thought of this method at all.

Xiang Yang believes that if he can be acquainted with male tiger-headed sea eagles, he will definitely be able to mix with female tiger-headed sea eagles.

On the top of the cabin, the female tiger-headed sea eagle seemed to be eating. The male tiger-headed sea eagle moved his lower body. Because of his perspective, Xiang Yang could not see it again.

"Yeah." Chen Yu nodded in satisfaction, then he looked around and asked in confusion: "Student Xiang Yang, we should be some distance away from the shore now? You don't want to cast a net to try the harvest?"

Today, sonar detection systems are basically installed on the ocean-going fishing boats of Chinese fishermen, but there is still a certain gap between my country’s sonar detection system compared to foreign countries, and it cannot accurately detect the fish on the seabed. At that time, there will be detection errors, and a few rare marine fish will be mistakenly detected as a large group of marine fish swimming across the bottom of the sea. Therefore, the fishermen in our country driving ocean fishing boats generally prefer to purse seine or trawl.

Xiang Yangxin said that you have been staring at the sea eagle just now, I must not be with you? How can you order the net to be used for fishing?

On the lips, Xiang Yang said: "No hurry, here is a country with seawater, there is a lot of sediment on the bottom of the sea, but the vegetation is sparse, not suitable for fishing, and there are not many marine fish. When it is time to put the net, I will order the net to be used for fishing."

Professor Chen Yu nodded slightly. Even if he is an expert in marine biology, he cannot compare with fishermen in fishing. There is no way. This is the profession of others. There is still a certain difference between professional and professional. .

Xiang Yang looked at Chen Qingsheng and pretended to ask: "Old Chen, what is the sonar detection system showing? Are there schools of fish under our sea area?"

Normally when going out to sea, Xiang Yang doesn’t ask about the sonar detection system. Xiang Yang’s fishing habits are based on his own experience and observation with the naked eye. Because he is plugged in, the sonar detection system only detects marine fish under the seabed. , Will take the initiative to inform Xiang Yang, and Xiang Yang decides not to scatter the net.

But not this time. There were too many professionals on board this time. Xiang Yang couldn't be too special in front of Professor Chen Yu and others.

In order to keep a low profile, Xiang Yang went out to sea this time and even endured it. He didn't get to the ship's gunwale to look into the sea. He was afraid that suddenly seeing a very precious and rare marine fish could not help but order to cast a net.

Chen Qingsheng doesn't doubt that he has him. Xiang Yang is the captain. The captain asked about the situation on the sonar detection system. Shouldn't this be reasonable?

"It’s hard to say, if there are no fish, there are a lot of small red dots under this sea area. These small red dots are marine life, but if the catch is abundant, these red dots are extremely scattered. It's like a big school of fish." Chen Qingsheng said.

Xiang Yang nodded, "Then wait for a while, and then cast the net later."

"Student Xiang Yang, you have to look at the sonar detection system every time you cast a net. Don't you just put the net off as soon as you go to sea and trawl it all the way forward?" Professor Chen Yu asked.

Many fishermen go to sea to fish. As long as the fishing boat has an engine, they will usually trawl forward after going out to sea. Regardless of whether there are fish in the sea, they will drag it all the way.

"First, we are an ocean-going fishing boat. If we trawl forward with too little catch, it will be a burden on fuel oil, and it is easy for the fish not to be towed. On the contrary, we are dragging up a whole boat of rubbish. Secondly, I don’t have a whole set on this boat. Sonar detection system? Of course I have to use it."

Professor Chen Yu nodded and smiled admiringly at Xiang Yang. From Xiang Yang’s words, he learned one thing that pleases him, that is, the fishing nets used on Xiang Yang’s boat, not the kind of scraping land. Juehu.com.

There is a kind of fishing net, the mesh of the mesh is very small, and there is a sharp iron hook at the bottom of the net. When the fishing boat is pulled by the fishing boat, the iron hook can even break the reef. The name of this kind of net is called Juhu net.

There is an advantage to trawling with a unique net, that is, as long as the trawl moves forward, it is absolutely impossible to lose money. This kind of fishing method like scraping the land, no matter whether there are fish in the sea or not, it is dragged for a few hours, at least the scallops living on the bottom of the sea, Crabs, conch and the like can get a lot, in short, they are more valuable than gas.

However, Juhu Net’s damage to the marine ecology is really too great. When it was dragged the last time, the seabed was really ploughed. There was no grass growing under the entire sea area, and all marine life was almost extinct.

"A friend of mine has a sonar detection system that was removed from a decommissioned submarine. Although it is an old device many years ago, it is still far ahead of the market in the civilian field~www.readwn.com~. If you are interested, I will help you ask later and see if he can sell it." Professor Chen Yu said.

Xiang Yang smiled with joy, "Of course I am interested, thank you teacher."

The joy of Xiang Yang's face was not pretending, he was really interested.

Even if Xiang Yang was on the hook, he couldn't have been standing on the side of the ship and staring at the water for twenty-four hours, right?

A more advanced sonar detection system is really important for fishermen.

Xiang Yang is very aware of the importance of sonar detection systems. Finland, a country with a very small land area, can become a major fishery country in the world seafood market, and it has a lot of sonar detection equipment that is listed as the highest level of confidentiality. Relationship.

"Don't rush to thank me, I don't know if you can get it done, I just ask you if you are interested, and this thing is not cheap." Professor Chen Yu laughed.

Xiang Yang nodded, "No matter what, thank you teacher first."

Professor Chen Yu nodded with a smile and stopped talking.

Xiang Yang looked at Professor Chen Yu's profile, and began to measure something in his head.

Don't look at Professor Chen Yu now seeming to have a heart to the seabed of tiger heads, humpback whales, and killer whales.

But in fact, as long as Xiang Yang takes out one thing, it is guaranteed that Professor Chen Yu will be able to rush back to the laboratory immediately without looking back, and remove the so-called killer whale, humpback whale, orcas sea eagle. The study of biological habits was thrown out of the sky.

That thing, the Nautilus, which is praised by scientists as an alien visitor, has been completely extinct on Earth. The giant nautilus, which was once the top overlord of the ocean, is the fossil of the straight-shelled Nautilus.

The straight-shelled Nautilus has always been regarded by scientists as a miracle in the history of life.
