my golden fishing village

Chapter 138 Named Balang
"Yellowfin tuna? Is it the Japanese food we usually eat?" Zhao Hao asked hastily.

"might have."

Chen Fan said with a smile: "The ones used in Japanese food stores may also be bonito. It has a strong reproductive ability. Because of the large quantity, the price is not high, and the quality is cheap. For example, the raw materials of canned tuna are basically bonito."

"Hahaha, Hiroko, you don't know what you eat is bonito, do you?"

Han Hanhua gloated.

Qian Ning shook his head and asked curiously, "Fanzi, this tuna probably weighs several hundred catties each. How long will it take to grow so big?"

"Yeah, ten years? Or 20 years?"

"It won't be that long."

Chen Fan explained with a smile: "Although this guy is several meters long and weighs several hundred catties, it actually grows up very fast. After mating, it only takes two or three days for them to hatch from fertilized eggs to young fish." , and then work hard to prey, and complete the development of the main organs of the body in the next period of time. It only takes about a month to grow from a fertilized egg that is difficult to detect with the naked eye to a juvenile fish.

In the juvenile stage, tuna like to live in groups on the surface of the ocean. If they can "grow up into adults" smoothly, they can reproduce in about 2 to 5 years. "

"One month!"

"This speed is too fast!"

"The main thing is to be able to eat."

"But don't be optimistic," Chen Fan changed the subject, "The survival rate of tuna is very low, only 0.01%, that is to say, about 99.99% of juvenile fish will either die naturally or be buried in the Other belly."

"what?"

"This, this elimination rate is too high."

Everyone was shocked.

In the beginning, they felt sorry for the flying fish, but the tuna, as a predator, was even more miserable than the flying fish.

"Yeah, it would be much better if it grows into an adult fish. Except for sharks, there are almost no natural enemies, because other fish can't catch up with it."

The size of tuna is like a torpedo. It is powerful and can swim at a speed of 75 kilometers per hour, which is close to the speed of a car running on the highway. This speed is among the best among fish.

It is particularly worth mentioning that tuna is not only an explosive player, but also an endurance player. It undergoes breeding and migration every year, ranging from several thousand kilometers to nearly [-] kilometers long.

Why is the swimming level of tuna so powerful? This is due to the two major functions of its body.

The first is a constant temperature, and the second is a strong body tissue.

Let’s talk about constant temperature first. Its blood circulation system is quite special. There are dense parallel veins and arterial blood networks next to the muscles. This powerful blood network can input nutrients to the muscles, and at the same time carry the heat generated by the muscles and send them to all parts of the body through blood circulation. Realize constant temperature.

Other fish basically lose fire when they encounter cold sea water, but tuna can still maintain a high degree of vitality and high-speed swimming.Conversely, if the body heat is too much, they can also be discharged into the sea water through the terminal arterioles.

What's even more exaggerated is that tuna can swim and sleep at the same time!
Most fish breathe by opening and closing their gills, but tuna is more direct, directly opening their mouths to inhale seawater.As it continues to swim forward, there will be a lot of water flow into the gills.So can its gills withstand such a strong water flow?

No problem, the gill surface of tuna can expand to 30 times the size of similarly sized fish.This allows it to obtain a large amount of oxygen in the water, making its heart stronger. Coupled with the rich myoglobin, its physical fitness is enough to kill a group of fish in seconds, laying a solid physical foundation for its thousands of miles of migration.

"Fanzi, how much does this tuna cost per pound?"

Han Hanhua joked: "It can't be tens of thousands of yuan, right?"

"almost."

"????"

"Is it really so expensive?"

Sun Biao and others were also stunned.

In this fishing net, at a glance, there are still twenty or thirty fish, so isn't that two or three million?

After all, they used to use small fishing boats, and basically did not catch tuna, let alone such a big one.

"Currently, the price of tuna on the market ranges from 400-1200 yuan per kilogram, that is, the price of tuna per catty is about 200-600 yuan. In addition, the price of tuna varies in different fishing seasons and in different port areas, so a piece of tuna is one or two meters long. Long, three to four hundred catties of tuna, almost tens of thousands."

Chen Fan smiled and said, "Didn't Haozi go to eat Japanese food?"

"Indeed, it's quite expensive."

Zhao Hao nodded.

Just such a plate, a few pieces of tuna fish can cost hundreds of dollars.

"It's so expensive..."

"It's expensive for a reason." Ji Yun said with a smile.

"Yes, tuna meat is low-fat, low-calorie, and rich in protein, which has become the first choice for people who lose weight. They can not only achieve the body's satiety, but also do not add excess calories and energy to the body. Burden. In addition, in the body of tuna, there is a substance called "DHA", which is often called "brain gold". Therefore, if you eat tuna regularly, it is very useful for the development of the human brain, so they also Became a regular in healthy meals prepared by parents for their children.

In addition to these, hyperlipidemia, high blood pressure, and high blood sugar have always been chronic killers of humans, and elements such as taurine in tuna can help the human body reduce the risk of disease and disease. If you have hair loss problems, you can also eat more Some tuna. "

"Can it also treat hair loss?"

"It's not that amazing, it's just that fish has more protein, so if you lose your hair, it's good to eat more protein."

"We know the tuna. What is the other fish? I've seen a lot of it?" Li Fangfang asked, pointing to the small spindle-shaped fish.

"That one is called the blue round trevally."

"What's the price?"

"It's far worse than tuna." Chen Fan shook his head.

"It's not just that it's too far away, it's too far away, this Balangyu." Wang Tiezhu also sighed.

"How much is it?"

"Five or six yuan a catty."

"How many?"

Zhao Hao asked again, he wondered if he heard it wrong.

"Five or six yuan."

Wang Tiezhu looked at him, indicating that you heard it right, this fish is just so worthless.

"Five or six yuan a catty..." Zhao Hao was stunned, "If you say that, even if it's ten thousand catties, it's only five or sixty thousand yuan, and it's still not as good as four or five tunas?"

"What do you think?"

Chen Fan was disappointed, but not unhappy.

Five to six million small yellow croakers is already a great surprise.

These 30 or [-] tunas can also be sold for [-] to [-], which is not bad.

"Why? Why is it so cheap?"

Zhao Hao is still puzzled.

"Are there many fish?"

Han Hanhua blurted out: "Things are rare and expensive, don't you know?"

"Besides that, there is another reason, Balang fish, it's not tasty."
