    ????????? It¡¯s not a shame, it¡¯s a very sad day when I have zero manuscripts saved. I have a party tonight, I got home at 11:30, and I coded until this moment, 2:21!  I say this not to complain, but to explain why the update is a bit late. Work hard and keep working hard!  ****

    Tuna farming is Japan¡¯s most proud fishery technology. They are the only one in the world who has mastered tuna farming technology.

    This technology, like ¡®Wagyu¡¯ breeding, is top secret in Japan. If Tezuka Kota hadn¡¯t wanted to please Qin Shiou, they would definitely not have been able to visit the seven islands of Izu.

    Of course, Qin Shiou didn¡¯t want to visit at all, he just wanted to take away these bluefin tuna.

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

    The bluefin tuna in Japanese waters belongs to the Pacific genus. Qin Shiou observed it at Tsukiji Market and could not see any difference between them and the bluefin tuna in his own fishery. Nishimura Rei said that there was a difference in taste. He thought this was nonsense and there was no difference.

    The technology of raising bluefin tuna in Japan can be traced back to the 1970s, when the famous Kinki University began research. In the 1980s, wild fish were raised into adult fish. However, due to the lack of wild tuna fry, it was difficult to expand the scale.

    Breeding technology made a breakthrough at the beginning of the 21st century. Kinki University finally realized whole-fish breeding, which means that even the fry are artificially bred.

    Although the total shipment volume is not very large compared to wild tuna, the breeding technology has become more reliable, and the shipment volume is also increasing year by year.  At this point, tuna farming has become a real and reliable thing.

    Artificially cultured tuna is called kindai-tuna in Japan, which means near-large tuna. This kind of fish looks similar to wild fish, but the meat quality and taste are different. The cultured tuna does not have enough activity, the fat content of the meat is too low, and the taste is not good.  .

    However, the unit price of near-large tuna is not much lower than that of ordinary wild-level bluefin tuna. The reason for this result is that the cultivation of near-large tuna is very 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 was not a small pond, but a circle of artificial super farms built around Li Island!

    About seven or eight kilometers away from Toshima, there are connected prestressed concrete pipe piles on the seabed. These pipe piles are similar to the piles used by Qin Shiou when he built the high-pile wharf, but they are much longer. When connected, they are enough.  A full two hundred meters!

    There are at least twenty such pipe piles around Toshima. These pipe piles are skeletons with fishing nets connected between them.  In this way, the fishing nets circle around Toshima and surround the entire sea area, forming what is called a tuna farm.  In addition, countless thick and thin water pipes stretch out from the island into the ocean. Oxygen generators are roaring on the island, and oxygen is continuously input into the seawater

    Seeing this scene, Qin Shiou understood why Tezuka Kota wanted to cooperate with him so much to catch tuna. The Japanese love this thing to the extreme, and the cost of eating this thing is really high.

    Qin Shiou asked Nishimura Leng the price of these pipe piles. Nishimura Leng said: "One piece is about 140 million yuan and can be used for 40 to 50 years."

    "Isn't this price too high, just to study tuna farming?" Qin Shiou asked in surprise. One hundred and forty million yen is almost seven million yuan, and twenty yen is one hundred and forty million yuan.

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

    Qin Shiou smiled bitterly and said, "As long as you don't eat this kind of fish, won't you save money?"

    When Nishimura Rei heard this, he became anxious and said: "How can you not eat it? If you can't eat such delicious food, what's the point of living?"

    Qin Shiou spurted out a mouthful of old blood!

    Winnie looked at the surrounding fishing nets and asked curiously: "Nishimura-san, are there no loopholes in these fishing nets? If there are loopholes, wouldn't the tuna escape?"

    Nishimura Rei explained: "There must be loopholes, but our research has found that tuna need to swim all the time in order to survive. This lifestyle has caused them to form the habit of swimming blindly. Unless they happen to find a loophole, otherwise  They¡¯re not going to find a loophole to get out.¡±

    Qin Shiou understands this. Bluefin tuna swims very fast and can reach a speed of seventy kilometers per hour.If you hit something at this speed, you will basically die.  Therefore, they have formed an unconditioned reflex. When they find an obstacle, they immediately change directions and swim instead of blindly trying to hit it.

    It¡¯s a pity that the Japanese encountered Qin Shiou this time. Bluefin tuna is naturally afraid of obstacles, but Qin Daguan can change the nature of these fish!

    Poseidon's consciousness quickly moved around Li Island. Qin Shiou encountered some bluefin tuna, but most of them were juvenile fish, which was about ten kilograms. The big ones were forty or fifty kilograms, and those over one meter long were rare.  , this little guy has no value.

    You can also see the character of the Japanese from this point. At the last auction at Tsukiji Market, many bluefin tuna caught from various sea areas only weighed 20, 30, 40 or 50 kilograms.

    But if you look at their own farms, they don¡¯t catch tuna before it matures. They typically don¡¯t treat other people¡¯s children as minors.

    To the south of Toshima is Shinjima. The breeding farm on this island has shares in Kiyomura Co., Ltd. Nishimura Rei can take Qin Shiou and his party to visit the interior of the breeding farm.

    When the boat docked, two men in security uniforms came up and asked for a body search. They were not allowed to bring cameras, mobile phones, or video recorders to the island. The reason was naturally to prevent anyone from filming the tuna farming technology.

    Qin Shiou didn¡¯t want these people to search him, so he simply didn¡¯t go up there and let Nishimura Leng take them around.

    As the ship was turning, Poseidon¡¯s consciousness was also turning. When we arrived at the Forbidden Island, we made a surprising discovery.

    The pipe pile pillars on the Forbidden Island are longer and extend to a depth of 300 meters in the ocean. The tuna here ranges from big to small, but overall they are still on the small side.  But these fish swim faster and have a spirit of their own, which is different from the lazy tuna in other farms.

    Qin Shiou found the answer after a quick glance at Xi Cun. As he guessed, the tuna in this farm were all wild seedlings.  If you can catch wild bluefin tuna, bring it back before it dies and put it in the farm on the Forbidden Island.

    Poseidon¡¯s consciousness was spinning inside. Qin Shiou took a look and saw that there were probably more than a hundred bluefin tuna inside. The number was less than in other farms, which had at least more than two hundred.

    This is also related to the nature of bluefin tuna, because they often maintain high-speed parades. If there are too many and they are not of the same population, collisions can easily occur.  Wild fish swim faster than farmed fish, so they are farmed at smaller densities.

    The waters controlled by Poseidon¡¯s consciousness start from the outside and collect in a circle. If you encounter tuna, immediately control it and give them a target. Swim to the North Atlantic and go straight to Daqin Fishing Ground.  (Remember the website address: www.hlnovel.com
