After turning around, Lin Feng was stunned that he didn't find a fish that could cost a million.

There are many fish, but most of them are homemade freshwater fish, with small octopuses and a few black fish and carp.

Let's try the sea fish!

Again, nothing expensive.

The starting price is not expensive, which means that there is no added value, even if Lin Feng gives the aura, the price of this fish will not rise much.

This was obviously not in Lin Feng's interests.

"Brother, buy fish?"

Lin Feng's search, his disappointed expression, quickly fell into the eyes of those who cared.

Lin Feng looked at the person who was talking to him, it was a red-haired young man. Red, is the kind of reddish hair.

The person looked good, Lin Feng nodded and said, "Yes, I want to buy some good fish, but this good fish is hard to find!"

"Good fish! You're in luck. Come on, come on. ”

The young man looks like if you meet me, you meet a nobleman.

"Follow me. I have good fish there. As he spoke, he led the way.

He looked so excited, so excited that he forgot to see if Lin Feng had followed.

Lin Feng thought about it, but still followed.

Walking out of the fish market, they walked to the docks.

It was a very small pier, which was supposed to be built by private individuals.

Before the person could walk in, he smelled a strong fishy smell.

"Don't mind, we stink a little here, but we definitely have good fish here. The red-haired young man said.

What he said was true, Lin Feng had already seen it, tuna.

Lin Feng actually saw a tuna here, so he immediately searched for it on the Internet.

Tuna (tuna) is a large, ocean-going and important commodity food fish. It is found in the warm waters of the world, and is closely related to mackerel, mackerel, mackerel, etc., and usually belongs to the same mackerel family. There is considerable variation within and between families. The classifications are also very different, and authorities have different opinions on this.

Tuna is also called tuna, tuna is called in Hong Kong, and Macao is translated as adong fish in Portuguese, most of which belong to the genus Tuna. The flesh of tuna is red in color, which is due to the high amount of myoglobin in the muscles of tuna.

Tuna swim fast. The instantaneous speed can reach 160 kilometers per hour, with an average speed of about 60-80 kilometers per hour. Tuna is found in the Indian Ocean, the central Pacific Ocean and the central Atlantic Ocean, and is a tropical-subtropical oceanic fish. Tuna swim a long way, and in the past, it was found swimming from California off the coast of Japan.

However, in Huaibei, no one has ever heard of a tuna catch. If there was, Lin Feng would definitely not know about it.

It is important to know that the price of tuna is relatively expensive compared to ordinary fish, and the price will vary depending on the part, ranging from 400 to 1200 yuan per kilogram, that is, the price of tuna is about 200 to 600 yuan per catty.

If there was tuna in Huaibei, Lin Feng would definitely sell it to the Japanese. Selling this thing, the profit is much thicker than that of a pufferfish.

The body of tuna can be basically divided into several parts: large belly, middle belly, naked body and cheek raiser. The fish in the large belly is rich in fat. Pink in color and the most expensive, mid-belly meat is the second most expensive in color and slightly darker in color than meat in the big belly area, and the meat on the back is bright red and equally delicious and delicate, called naked, with less fat, and the cheapest price.

Chilled bluefin tuna belly meat can even be sold for 2,500 yuan a kilogram. But I don't know. Bluefin tuna has two pieces of cheek raiser meat that are the most precious and expensive, and the market price of each tael is 2,800 yuan. In Japan, the owners of Japanese restaurants are reluctant to sell them, and only use them to entertain their most distinguished and important friends.

The reason why it was bluefin tuna was because Lin Feng saw that among the five tuna, there was really one bluefin tuna.

Although it is not big, it looks like it should be two hundred pounds.

Surrounded by five tuna. There was a family of three smoking around them, looking gloomy and miserable.

"Brother, uncle. I found someone to buy fish. The red-haired young man shouted loudly before he could get closer.

"What? Found where?"

Hearing that someone was buying fish, the family of three hurriedly stood up. Look around.

"Well, it's not. This is the brother who wants to buy our fish. The red-haired youth immediately let Lin Feng out.

"You're going to buy our fish?"

Seeing Lin Feng, they still didn't believe it.

In the past few days, there are quite a few people who come here to see the big fish, but none of them have bought them.

"Yes. How can this fish be sold?" Lin Feng nodded and said.

"Two hundred and one pounds. The young son hurriedly said.

Lin Feng looked at the fish and just shook his head.

The son said angrily: "Don't bully people, I checked it on the Internet, and this fish is only 211 catties." ”

"Two hundred and one pounds, why didn't you sell it. Lin Feng shook his head and smiled.

"This, this ......"

They don't want to say it, and they don't want to say it.

"You didn't kill you, did you?" Lin Feng said suddenly.

"Yes, yes, we didn't kill it, we raised it with water. ”

They are also telling the truth, in this area, if they catch freshwater fish, they will raise them with water. Killed fish are not as valuable as live fish. But what kind of fish is this? This is tuna.

The tuna has a spindle-shaped body with a torpedo body shape and a slightly rounded cross-section. With its powerful muscles and crescent-shaped tail fin, the scales have been reduced to small round scales, and it is suitable for fast swimming, with a general speed of 30-50 kilometers per hour and a maximum speed of 160 kilometers per hour, which is faster than the fastest animals on land.

If the tuna stops swimming, it will suffocate, because the tuna always opens its mouth when swimming, so that the water flows through the gills and absorbs oxygen to breathe, so it can only continue to swim at high speed throughout its life, even at night without rest, but only slows down the swimming speed and reduces metabolism (this kind of mouth opening makes the water flow directly through the gills to breathe oxygen breathing breathing is called impact breathing, tuna belongs to impact breathing. ）。 The color of the belly of the tuna is lighter than that of the back, so that when viewed from the sea, its body color is similar to that of the sea, and the tuna can travel thousands of kilometers and can travel across the ocean, and is called "fish without borders". According to scientists, tuna is the only large fish capable of fast swimming over long distances, and experiments have shown that it can swim up to 230 kilometers per day.

The tuna is one of the fastest swimming marine animals, and can only be matched by the most ferocious sharks and dolphins. When the tuna swims at full speed, it can reach speeds of up to 55 knots per hour.

In order to replenish the energy expended by the constant swimming and vigorous metabolism, the tuna must be constantly fed. A pound of tuna eats 18 percent of its body weight in one meal, which is equivalent to a 150-pound man eating two large roosters with bones in one meal.

The gill muscles of tuna have deteriorated, so they must swim constantly so that fresh water flows through the gills for oxygen. If the tuna stops swimming, it will die of suffocation due to lack of oxygen.

This family is good, they don't kill the tuna when they catch it, but they feed it with water, can you feed it?

If this fish was so easy to raise, it wouldn't be so expensive.

"So, you didn't bleed the fish anymore?" Lin Feng asked.

"Bloodletting? Why bloodletting? This blood is precious. The old man said.

I don't know when a saying began to prevail in this part of Huaibei - blood is precious, with high nutritional value, and the blood in the ingredients should not be released, but should be preserved in the body and eaten together.

"This is tuna, in order to ensure freshness, after fishing, immediately after the fishing boat bloodlet treatment after rapid refrigeration of about -4 ~ 0 degrees, in the return, storage, distribution and terminal storage of all aspects are kept at a low temperature below zero, so that the fish body is in a refrigerated state, in the stiff period to maintain the elasticity of the fish, so that the fish body is restored to a fresh state, its meat nutrition, shape and color are the same as live fish. It took only 15 hours from the time the tuna was caught and shipped to Beijing, and the freshness of the tuna was preserved to the maximum. ”

"If left untreated, the dead fish blood will quickly destroy the flesh of the fish. From the expensive rose red to the dark red that no one wants, the meat will become bitter. ”

"Ah, son, hurry up, put these fish in the refrigerator. ”

The head of the family is also aware of it. At this time, what is the use of putting it in the refrigerator. The fish quality has been ruined.

It's like on July 13, five college girls picked up a bluefin tuna off the coast of Cornwall, England. This quickly became a piece of world-class news

"This is a giant bluefin tuna, and the media estimates it are about 650,000 pounds, which is 7 million yuan. ”

But I don't know if I forgot to say it in the news, or if I used the Spring and Autumn brushwork.

Once tuna is caught, the standard procedure is that after receiving the order, the fisherman catches the bluefin tuna with a professional sling hook, and then quickly bleeds the fish, so that the fish does not become stiff, and the blood is drawn from the bone marrow, so the fish will remain clean inside. After customs clearance, when it arrives at the receiving place, such as a city in Asia, the ice water will be replaced to ensure that the temperature of the fish is maintained at 0 degrees Celsius.

And the tuna looked like it had been dead for a long time and had changed color.

Otherwise, even if five college students did not know the hardships of life and sent the fish to the research institute, some merchants and taverns would sell it at a high price.

In Europe and the United States, a large number of university fees need to be borne by themselves, even if they live in an ivory tower, it is difficult for them to refuse the temptation of money, if their tuna is not spoiled, it is impossible to sell it at all.

Just like these five tuna of theirs, if they don't kill them quickly and blet them freeze after catching them, but want to raise them with water like freshwater fish for a high price, it can only be said that they have been miserable by experience.

"Dad, we don't have such a big refrigerator. ”

The son turned around and wanted to freeze the fish, but when he entered the house, he found that they didn't have such a big refrigerator.

When you catch tuna, you don't know that you have to kill it immediately and let it go, but you don't even have a freezer for freezing.

This made Lin Feng wonder: "Uncle, aren't you tuna fishing?"

After all, the family's behavior is so strange that if they catch tuna, they can't understand it at all.

Those who know everything about tuna fishing and those who go bankrupt. I don't understand anything, and I dare to go to the sea to catch tuna. Do you think that the price of three barrels of oil is low, and they help to increase the turnover? )
