There were people on the boat who didn't understand and secretly asked, "Isn't albacore tuna worthless?" ”

Although he grew up by the sea, he had few opportunities to touch tuna, so it is not surprising that he did not understand.

"It's not very valuable, and it is said that this tuna is used to make canned food." The man next to him replied.

"I thought tuna was worth a lot!"

"Not necessarily, even if the same tuna is produced from different places, the price is very different. I've heard people say that no one wants tuna in Russia. ”

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

They know that seafood depends on the place of origin, but generally speaking, the higher the dimension, the colder the sea, and the better the quality of the fish. It stands to reason that Russian seafood should be delicious, right? It shouldn't be cheap, 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: "Most of the tuna in Russia is rough in flesh and has a strong fishy smell, so even Russians rarely eat Russian tuna." ”

Moreover, when Russia deals with tuna, it is mostly eaten by the pickling method, that is, the tuna is marinated into salted dried fish.

Relatively small tuna can even be bought for about ten yuan in Russia for a catty.

Of course, there is another important reason for people's cheapness, and that is production.

Tuna is produced in high quantities in Russia.

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

"Brother Hua, the processing factory in our village also makes canned food, right?" Someone asked.

"Hmmm! It's made of canned fish. ”

Canned food, in China, it seems that the market is not large, the sales are relatively good, in the south there is canned dace with tempeh, in the north is canned yellow peaches.

China, however, is the largest producer of canned food, mainly exporting.

Foreigners don't like to cook, so canned food is popular. People hoard food, canned food is indispensable, you can eat it when you open the can, it is really convenient.

Unlike our China, we have to pay attention to the freshness of the ingredients, and we go out to buy vegetables and cook every day, who will eat canned food every day? Isn't that sick?

When Zhang Yaohua and the others were about to reach their destination, suddenly, a meteorite fell from the sky and landed in the sea on the right side of the fishing boat, startling many people on board.

"I almost smashed our boat with my mother in my mouth."

Don't look at only a small piece, if you really hit the ship, the ship may be penetrated.

Looking at the situation of the sea being smashed, you know that the power is not small.

"Didn't you say that meteorites are worth money? Fish! "It was suggested.

"I don't know how deep it is! How to fish? Are you going? ”

Zhang Yaohua checked and saw that the sea where they were located was only a few tens of meters, less than a hundred meters, which could be said to be a shallow sea. This is rare on the high seas.

As we all know, the high seas are far from the mainland and are usually deeper.

Of course, there are always exceptions, and the ocean also has continental shelves, trenches, basins and ridges. Here, perhaps, it is the ridge of the ocean.

The continental shelf is a shallow zone of the sea that is bordered by the coast and gently slopes towards the sea. The outer edge of the shelf is mostly 100 to 200 meters deep, where the slope turns significantly and extends down to a steep continental slope.

A trench, as the name suggests, is a trench of the sea, which can reach a maximum depth of more than 10,000 meters. At present, only a very small number of submarines can reach it.

A basin is a basin with many low flats at the bottom of the ocean, surrounded by relatively high submarine seamounts, and this kind of structure similar to a basin on land is called a basin or ocean basin.

Ridges are also known as ridges and are sometimes referred to as "seamounts". The long, narrow ocean bottom highlands, generally below the sea surface, can reach 3 to 4 kilometers above the seabed on both sides.

"Don't have any ideas? Then I'll go down and take a look. Zhang Yaohua said with a smile.

He put on his diving gear.

Zhang Yaowei was not worried that his eldest brother would go into the water alone, so he hurriedly 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 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 approached each other.

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

I saw the dense steamed crabs on the bottom of the sea.

That's right! It's a steamed crab, not small, and they seem to be molting.

Everyone also knows that if crabs want to grow up, they basically have to go through molting, and some crabs even have to go through more than ten or twenty times in their lives.

The shell itself is not large, they need to take off the shell that is not out of size, and the soft shell will grow slowly.

Zhang Yaohua went straight to the meteorite.

If it weren't for the gold finger, even if I knew it had fallen here, I am afraid it would be difficult to find.

When I picked it up, it was the size of two fists, and the surface of the meteorite was burned smooth and had a glass texture. This meteorite, I don't know what kind of breed.

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

Like lunar meteorites, Martian meteorites, etc., they must be worth a lot, one gram is tens of thousands.

You must know that if human beings want to study the lunar soil, they need to spend a huge amount of manpower, material and financial resources to get it back, and usually only a little bit.

The Yankees gave us only 1 gram back then.

You heard it right, only 1 gram.

It can be seen how precious things related to the moon are. Although meteorites are different from the original lunar soil, they are also very valuable for research.

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

After getting the meteorite, Zhang Yaohua gestured to his second brother and Shui Wang.

They returned to the ship.

A crowd of onlookers.

"This is the meteorite that just fell? It's pitch black. ”

"Surely! Don't see any burnt marks on the surface? ”

Although none of them knew how to identify it, when they saw the burnt marks, they knew that they were right, and it was the piece that had just fallen.

In fact, what you see is a molten shell on the outside.

Before the meteorite falls to the ground, it has to pass through the dense atmosphere, and the meteorite rubs against the atmosphere during the landing process to produce high temperatures, causing the surface to melt and form a thin layer of molten crust.

As a result, the surface of the newly landed meteorite has a black molten crust with a thickness of about 1 mm.

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

He didn't mean to be scary, the meteorite would be exposed to the sun's cosmic rays and galactic cosmic rays in space before it fell to Earth, and it would be somewhat stained.

Especially if this has just fallen, the concentration of radiation may be harmful to the human body.

Those that have been falling for a long time have no effect.

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

Shui Wang came from there to ask, do you want to go down the net to catch a few nets?

Zhang Yaohua is not very interested, and the price of steamed crabs is average. Mantou crabs are almost all hard shells and have very little meat content, so fishermen do not like this kind of sea crab very much.
