Rushing to the sea: I can see the prompts

Chapter 169 Meteorite Falls
Someone on the boat who didn't understand asked secretly: "Isn't albacore valuable?"

Although he grew up by the sea, he had few opportunities to come into contact with tuna, so it was not surprising that he didn’t understand it.

"It's not very valuable. It is said that this kind of tuna is used for canning." The person next to him answered him.

"I thought tuna was all valuable!"

"That's not necessarily true. Even if it's the same kind of tuna, but it comes from different places, the price will be very different. I've heard people say that not many people want Russian tuna."

As soon as these words came out, many people on the boat were confused and looked at the man.

They know that seafood depends on the place of origin, but generally speaking, the higher the dimension and the colder the sea water, the better the quality of the sea fish.Logically speaking, Russian seafood should be delicious, right?It shouldn’t be cheap and no one wants it!

The guy spread his hands: "Don't look at me, I heard about it too."

So, everyone looked at Zhang Yaohua.

Zhang Yaohua nodded: "Russian tuna is mostly rough in texture and has a strong fishy smell, so even Russians rarely eat Russian tuna."

Moreover, when tuna is processed in Russia, it is mostly eaten through the pickling method, that is, the tuna is pickled into dried salted fish.

Relatively small tuna can be purchased in Russia for around ten yuan per pound.

Of course, there is another important reason why they are so cheap, and that is the output.

Tuna is highly produced in Russia.

No matter what it is, as long as the output is high, the price will be low, which is the law of the market.

"Brother Hua, the processing factory in our village also makes cans, right?" someone asked.

"Yeah! They make canned fish."

The market for canned food seems not to be big in China, but the sales volume is relatively good. In the south, it is canned dace with black bean sauce, and in the north, it is canned yellow peach.

However, China is the largest producer of canned food, mainly for export.

Foreigners don't like to cook, so canned food is very popular.When people stock up on food, canned foods are indispensable. You can eat them right out of the cans, which is really convenient.

Unlike us in China, where the ingredients must be fresh and we go out to buy food and cook every day, who would eat canned food every day?Isn't that a disease?
When Zhang Yaohua and the others were approaching their destination, suddenly, a meteorite fell from the sky and landed in the sea on the right side of the fishing boat, shocking many people on the boat.

"I grabbed his old mother and almost hit our boat."

Although it is only a small piece, if it really hits the ship, the ship may be penetrated.

Looking at the way the sea surface was smashed, you can tell that it was quite powerful.

"Isn't it said that meteorites are valuable? Get them!" someone suggested.

"I don't even know how deep it is! How can I fish it out? Are you going?"

Zhang Yaohua checked and found that the sea they were in was only a few dozen meters, less than 100 meters. It could be said to be a shallow sea.This is rare on the high seas.

We all know that the high seas are far away from the mainland and are usually deeper.

Of course, it is not absolute. There are always exceptions. The ocean also has landforms such as continental shelves, trenches, ocean basins and ridges.Here, maybe it is the ridge of the ocean.

The continental shelf is a shallow sea area adjacent to the coast and gently sloping toward the sea.The water depth at the outer edge of the continental shelf is mostly 100 to 200 meters, where the slope changes significantly and extends downward into a steep continental slope.

A trench, as its name suggests, is a trench in the ocean, with a maximum depth of more than 1 meters.Currently, only a handful of submersibles can reach it.

Ocean basins are many low and flat areas at the bottom of the ocean, surrounded by relatively high undersea mountains. This structure similar to basins on land is called a sea basin or ocean basin.

The ridge is also called a sea ridge, sometimes also called an "undersea mountain range".The long and narrow plateau at the bottom of the ocean is generally below the sea surface and can reach 3 to 4 kilometers above the seafloor on both sides.

"No idea? Then I'll go down and take a look." Zhang Yaohua said with a smile.

He put on his diving gear.

Zhang Yaowei was worried that his elder brother would go into the water alone, so he quickly followed.

Ah Hui said to his brother: "You go too." So the three of them went into the water and dived from different boats.

Fortunately, the sea water is also clear, and the three of them can look at each other from a distance and see each other.

As they dived, they moved closer to each other.

Arriving at the bottom of the sea, Shui Wang and Zhang Yaowei were stunned.

I saw densely packed steamed bun crabs on the seabed.

That's right!They are steamed bun crabs, quite big, and they seem to be shedding their shells.

As we all know, if crabs want to grow up, they basically have to shed their shells. Some crabs even have to go through it more than ten or twenty times in their lives.

The shell itself does not grow very big. They need to take off the shell that does not fit the size, and then the soft shell slowly grows.

Zhang Yaohua went straight to the meteorite.

If it weren't for the golden finger, even if I knew it fell here, it would be difficult to find it.

When I picked it up, I saw it was as big as two fists. The surface of the meteorite was burnt smooth and had a glass texture.I don’t know what kind of meteorite it is.

According to Zhang Yaohua's understanding, there are many types of meteorites, and not all meteorites are so valuable.

Like lunar meteorites, Martian meteorites, etc., they must be valuable, tens of thousands per gram.

You know, if humans want to study lunar soil, they need to spend huge manpower, material and financial resources to get it back, and usually only a little bit is available.

The Yankees gave us only 1 gram back then.

You heard it right, only 1 gram.

This shows how precious things related to the moon are.Although meteorites are different from the original lunar soil, they are also of great research value.

As for the Mars ones, they are even more valuable.

After getting the meteorite, Zhang Yaohua made a gesture to his second brother and Shui Wang.

They returned to the ship.

A crowd of people watched.

"Is this the meteorite that fell just now? It's pitch black."

"It must be right! Didn't you see the burnt marks on the surface?"

Although they didn't know how to identify it, when they saw the scorched marks, they knew they had found the right one and it was the piece that had fallen off just now.

In fact, what everyone sees is the outer molten crust.

Meteorites have to pass through the dense atmosphere before falling to the ground. During the fall, the friction between the meteorites and the atmosphere generates high temperatures, causing the surface to melt and form a thin molten crust.

Therefore, the surface of newly landed meteorites has a layer of black molten crust with a thickness of about 1 mm.

"Okay, don't come around, there might be radiation!" Zhang Yaohua said to everyone.

He didn't mean to scare people. Before it fell to the earth, the meteorite would be exposed to solar cosmic rays and galactic cosmic rays in space, and it would be contaminated to some extent.

Especially if it has just been dropped, the radiation concentration may cause harm to the human body.

Those that have fallen for a long time have no effect.

When everyone heard this, they took a few steps back.

There was a question from Shuiwang, do you want to lower the net and catch a few nets?
Zhang Yaohua is not very interested, and the price of steamed bun crab is average.The steamed bun crab is almost entirely covered with a hard shell and contains very little meat. Fishermen do not like this crab very much.
