Chapter 536

It's hard not to blow or black. It's hard to save the manuscript to zero. There's still entertainment tonight. When you get home at 11:30, the code word comes to this moment, 2:21! This is not to complain and tired, but to explain the reason why it is a little late. Work hard and continue to work hard****

Tuna Farming is the most proud fishing technology in Japan. In this regard, they are the only one in the world. Only they have mastered Tuna Farming Technology.

This technology, like "he Niu" breeding, is a top secret level in Japan. If Tezuka xiaotai didn't want to please Qin Shiou, they wouldn't be able to visit Izu seven islands.

Of course, Qin Shiou didn't want to visit at all. He just wanted to come and how to take these bluefin tuna.

Bluefin tuna is the most precious fish in the tuna genus, but it is also divided into several subspecies, Atlantic bluefin tuna, Pacific bluefin tuna and so on, of which the most precious is Atlantic bluefin tuna.

The bluefin tuna in Japanese waters belongs to the Pacific Ocean. Qin Shiou has observed them in the Tsukiji market and can't see the difference between them and the bluefin tuna in his own fishing ground. Nishimura Leng said there was a difference in taste. He thought it was bullshit and fart difference.

Japan's bluefin tuna culture technology dates back to the 1970s, when the famous Kinki University began to study it. In the 1980s, wild fish were raised as adult fish. It was only because of the lack of fry of wild tuna, it was difficult to expand the scale.

At the beginning of the 21st century, there was a breakthrough in breeding technology. Kinki University finally realized whole fish breeding, which means that even the fry are artificially bred.

Although the total shipment is not very large compared with wild tuna, the breeding technology has been more reliable, and the shipment is also increasing year by year. So far, breeding tuna has become a real and reliable thing.

Cultivated tuna is called kindai-tuna in Japan, that is, near large tuna. The appearance of this fish is similar to that of wild fish, but the meat taste is poor. The activity of cultured tuna is not enough, the meat fat content is too low, and the taste is not good.

However, the unit price of near large tuna is not much lower than that of general wild bluefin tuna. The reason for this result is that the breeding of near large tuna is expensive, which is more expensive than catching a wild fish.

When Qin Shiou arrived at li island by boat, he knew why Tuna Farming cost so much. This farm is not a small pond, but a circle of artificial super farms built around li island!

At the bottom of the sea about seven or eight kilometers away from Li Island, there are prestressed concrete pipe piles connected one by one. These pipe piles are similar to those used by Qin Shiou when building a high pile wharf, but the length is much longer. After connecting, it is full 200 meters!

There are at least 20 such pipe piles around the Lee island. These pipe piles are skeleton and connected with fishing nets. In this way, the fishing net surrounds the island and surrounds the whole sea area, forming the so-called tuna farm. In addition, countless thick and thin water pipes stretch out from the island into the ocean, the oxygen generator starts roaring on the island, and the oxygen is continuously input into the seawater

Seeing this scene, Qin Shiou understood why Kota Tezuka wanted to cooperate with him to catch tuna. The Japanese love this thing has become Tai. The cost of eating this thing is really big.

Qin Shiou asked Xicun Leng about the price of these pipe piles. Xicun Leng said, "one is about 140 million yuan, which can be used for 40 to 50 years."

"It's too expensive, just to study Tuna Farming?" Qin Shiou asked in surprise. 140 million yen is almost 7 million yuan, and 20 pieces are 140 million yuan.

Nishimura Leng said seriously, "the value of scientific research is unlimited. If the tuna breeding technology is fully mature, do you know how much money we can save in Japan?"

Qin Shiou said with a bitter smile, "as long as you don't eat this fish, won't you save the money?"

On hearing this, Nishimura Leng was worried and said, "how can you not eat? If you can't eat this delicious food, what's the meaning of living? "

Qin Shiou spewed out a mouthful of old blood!

Winnie looked at the fishing nets around and asked curiously, "West Village sang, are there no loopholes in these fishing nets? If there are loopholes, won't the tuna escape? "

Nishimura Leng explained: "there must be loopholes, but our research found that tuna need to swim all the time in order to survive. This lifestyle makes them form the habit of blind swimming. Unless they happen to drill loopholes, they won't look for loopholes."

Qin Shiou knows that bluefin tuna swims very fast and can reach a speed of 70 kilometers per hour. If it hits anything at this speed, it is basically dead. So they form a non conditional reflex. When they find that there is a barrier, they immediately change direction and don't blindly hit it.

Unfortunately, the Japanese met Qin Shiou this time. It's good that bluefin tuna is naturally afraid of obstacles, but he can change the nature of these fish!

Poseidon consciousness quickly turned around in li island. Qin Shiou met some bluefin tuna, but most of them are juvenile fish, that is, they look like about ten kilograms, 40 or 50 kilograms, and those more than one meter long are rare. This little guy is of little value.

From this, we can also see the character of the Japanese. At the last auction in the Tsukiji market, many bluefin tuna caught from major sea areas looked like only 20 or 30 kilograms or 40 or 50 kilograms.

But look at their own farms. Tuna are not caught before they are mature. They typically don't treat other people's children as minors.

To the south of Lee island is Xindao. The farm on this island has shares of Xidai village Co., Ltd. and xichunling can take Qin Shiou and his party to visit the farm.

When the boat docked on the dock, two men in security uniforms came up to search. They were not allowed to bring cameras, mobile phones or video recorders to the island. The reason was naturally to prevent someone from photographing tuna breeding technology.

Qin Shiou didn't want these people to be searched, so he simply didn't go up. Just let Xicun Leng take them around.

The ship was turning, and the Poseidon consciousness was also turning. When we arrived at Shenjian Island, we had a surprise discovery.

The pipe pile pillar of Shenjian island is longer and extends to a depth of 300 meters. The tuna here are large and small, but the whole is still small. But these fish swim faster and have their own spirit, which is different from those lazy tuna in other farms.

Qin Shiou beat around the West Village edge and found the answer. As he guessed, the tuna in this farm are wild seedlings. If you can catch the wild bluefin tuna, bring it back before you die and put it in the farm of Shenji island.

The Poseidon consciousness was turning inside. Qin Shiou looked. There were about 100 bluefin tuna in it, less than other farms, and at least 200 in other farms.

This is also related to the nature of bluefin tuna, because they often maintain high-speed parade. If they are too many and not a population, they are prone to collision events. Wild fish swim faster than cultured fish, so the culture density is smaller.

The water area controlled by Poseidon consciousness began to collect in circles from the periphery. When you encounter tuna, you immediately control it, give them a target, swim to the North Atlantic and go straight to Daqin fishing ground.
