Chapter 241 Experiment on King Crab Survival Rate

After catching a wahoo, Qin Feng stopped fishing in the afternoon.

The three of them leisurely spent two days at sea, and the vanguard arranged by Gu Junnan arrived in a speedboat.

These are explorers, who will first dive to determine the specific location of the wreck and a preliminary plan to salvage it.

There will be staff arriving later, including the large salvage ship.

It didn't take long for the staff to determine the salvage plan.

The three sunken ships are almost well preserved and can be salvaged directly with the ship, and one has been connected to the coral, so it can only be considered that the valuables inside are moved out.

After explaining everything about the salvage here, Gu Junnan asked Qin Feng to set sail and go to Sri Lanka to stop the boat there.

Another three days passed, and the Canglong entered Sri Lanka. After giving a tip, the coast guard here did not check the ship at all.

The three of them disembarked with two suitcases and flew to Xingdao that day.

They came to Xingdao not to rest, but to appraise the treasure.

Gu Junnan called in experts to appraise the two vases, including the 'Zhou' token.

The vases were quickly identified as genuine, but the origin of these two vases still needs experts to continue to study and explore.

From Qin Feng's mouth, I learned the token, the map, and the photos of the clothes worn by the skeleton. After several days of research, the experts found some answers from some ancient books.

The owner of the token is likely to be the bandit Wang Yang in the late Ming Dynasty and the anti-Qing hero Zhou Hezhi. According to ancient records, Zhou Hezhi disappeared after failing to fight against the Qing Dynasty.

As a person wanted by the imperial court at that time, and a robber who robbed the rich and helped the poor in his early years, the most likely reason why Zhou Hezhi disappeared was because he went abroad.

Experts can determine the identity of the owner, mainly because of the token.

Zhou Hezhi's official position was not small. In [-], he was named Marquis of Pingyi, and he was given the seal of General Pingyi.

This token was not the seal of the general at that time. According to experts' speculation, this token should have been created by Zhou Hezhi who left the country after failing to join Zheng Chenggong and started his old business again.

There is a big Zhou character on the surface of the token, but there are two very small "Ping Yi" characters on the lower back.

It is these two words that allow experts to guess the identity of the token owner.

There is just one thing that puzzles the experts, so Zhou Hezhi's genealogy says that he died in battle and did not go abroad, but there are many documents saying that he disappeared.

Therefore, he is not 100% sure whether the owner of the token is Zhou Hezhi or not.

But regardless of whether it was true or not, those four sunken ships should have been the targets of his robbery at the time, but he didn't know what happened to cause the merchant ship to sink, so he drew a map on his own.

These mysteries may never see the day again.

Of course, Qin Feng doesn't care about these things, he only knows that his vase is genuine and of high value.

"What do you want to do with these two vases?"

After the vase was appraised, Gu Junnan asked about their plans and put forward his own suggestions.

"My suggestion is not to open the auction, but to find buyers from several countries in Southeast Asia, and perhaps secretly send the news to the British Museum."

"Of course, you can also donate the big blue and white jar to a certain museum in the country."

"Well..." Li Xinyue thought for a while, then blinked her big eyes and looked at Qin Feng.

She basically has the final say on the trivial matters at home and on matters related to the cultivation of her son.

But such a big deal of hundreds of millions, from the beginning of the engagement, was decided by Qin Feng.

Qin Feng hesitated for a while, the Portland vase has nothing to say, it must be auctioned.

But should the big blue and white jars be donated to the country for free?

But I found this on the high seas of the Indian Ocean. Theoretically, this vase does not belong to China.

Sending it to a certain museum is just giving warmth to others for no reason. Others may not remember their goodness, so it is better to sell it.

"Well, the Portland vase will be auctioned normally. For the blue and white vase, see if there are any museums in China to buy it. If there is, we can trade it in private. It doesn't matter if the price is lower."

Qin Feng finally made a decision. Regarding the big blue and white pot, he felt that it was enough for him to give Huaxia a discount, and there was no need to be so noble.

And after knowing the value of these two vases, he also had a new idea, that a lot of money might be used at that time, so he had to be prepared first.

"Okay, then I'll help you arrange it." After Gu Junnan understood Qin Feng's thoughts, he helped to contact the buyer.

"By the way, Jun Nan, the blue and white jars can only be discounted at domestic museums. If the price is at most 20% off!"

"20%? You are really willing, I know, I will arrange it for you." Gu Junnan nodded, then called his secretary and asked her to arrange to contact the buyer.

After ordering, he said to Qin Feng again: "What are your plans for the next period of time, whether to participate in the salvage of the sunken ship or continue to travel? I am very busy now, and I have no time to play with you."

Li Xinyue and Qin Feng looked at each other, and said: "Then let's go back to China and rest for a few days before talking about it! It will take a long time to salvage the sunken ship. Whether we participate in the salvage or continue to travel, let's talk about it later!"

Gu Junnan nodded: "Alright, then I'll go to work first. By the way, you'd better deposit the vase in the bank for safekeeping. It's too dangerous to take it with you."

After speaking, he left to do his own business.

Qin Feng and Li Xinyue didn't stay in Xingdao too long, the vase auction would definitely take some time, so they came to the Swiss bank in Xingdao to open an account and kept the vase in the bank.

Although the storage fee is high, it is much safer than taking it with you, and they will not be kept for long.

After staying in Xingdao for one night, the two flew back home the next day.

After staying with his family for two days, Qin Feng came to Dalian alone to see how Qin Lei's breeding base was doing.

But when he came to Dalian, he heard a bad news.The waters where king crabs live are too deep, and today's technology simply cannot breed them. At most, we can only build a temporary breeding distribution center.

This kind of temporary breeding method is to import king crabs from abroad, and then raise them in a temporary breeding center for one to two months to ensure the vitality of the king crabs.

In this way, we can ensure that most of the king crabs sold in the market are fresh and alive.

But this situation is far from what Qin Lei and others want. They want to breed, but they don't have super large cages that can sink into the deep sea.

Even if there is, the investment is very large, and the cost is too high, so there is no meaning of breeding.

But Qin Lei didn't waste his efforts during this time, he has been researching and selecting the kind of king crabs that can survive in relatively shallow waters.

If he could survive in the sea within 100 meters, then he still planned to try it.

"How do you try, even if there are king crabs that can survive in relatively shallow waters, how to solve the seine problem?" Qin Feng asked with a frown.

Qin Lei showed a mysterious smile: "I was going to give up, but you found the sunken ship, which gave me new inspiration."

Qin Feng asked curiously: "What inspiration?"

"We can directly make shaped breeding cabins and put them into the sea, so crab seedlings and food can also be directly put into the breeding cabins with tools."

"Ah, the cost is very high, and can you guarantee that the breeding cabin can withstand the long-term corrosion of seawater?"

"The initial cost is really high. The main cost is the construction of the breeding cabin. After all, it needs to be guaranteed to withstand seawater corrosion for a long time. Naturally, the quality of the breeding cabin must be guaranteed. This is the only feasible way after I find someone to study."

"Moreover, 100 meters is the depth of water we can breed. If it is deeper, it will be quite troublesome to breed. If possible, the water depth is 50 meters is the best."

"I'll take you to see the experiment we're doing now."

As Qin Feng said, he couldn't wait to take Qin Feng on a speedboat, and then sailed to a sea area about [-] nautical miles away. Qin Feng saw dozens of buoys immediately.

And there is a small island not far from this sea area.

Qin Lei pointed to the small island in the distance and said: "If the breeding farm is really established, that small island will be our future foothold."

"Also, look at the numbers on these buoys. Thirty means that the crab pots are placed on the seabed at a depth of 30 meters, and 40 meters means that the seabed is at a depth of 40 meters. The three colors of red, blue and yellow also represent three types of king crabs. "

"Currently, the survival rate of the red king crab is the highest. Within one month, the survival rate reached 70% at a water depth of 100 meters to 60.00 meters."

"It's a pity that the water depth environment of about 50 meters does not know what is going on, and the survival rate directly drops by about 20%."

Qin Feng nodded clearly, the survival rate within one month is above 60.00%, which is considered a very good survival rate.

Of course, this survival rate is still very false, after all, the number of king crabs in the experiment is only a small number.After the base number is large, the specific situation is unknown.

And if you want to breed them, you have to let them sit for at least half a year. Only then can you know whether the king crabs can really survive at this depth, or if they are more tenacious and hold their breath for a while.

Secondly, the temperature in summer is also a problem. The highest temperature in Dalian in summer is about [-] degrees, while the temperature of king crabs in summer needs to drop below [-] degrees.

The temperature at a water depth of 100 meters may not drop below [-] degrees. The most important thing is whether the king crab can survive.

Then Qin Lei drove the speedboat to the Oriental Dragon, which was transported from the beautiful country, and then he asked Qin Feng to change into a diving suit, ready to be taken to dive for observation.

"We need to ensure the accuracy of the data, so the divers go down to feed the food themselves, otherwise the crab cage may be pulled up and down, which may also lead to the death of the king crab."

Qin Feng nodded when he heard the words, and it is true that fishing king crabs will cause the possibility of death.

After warming up and putting on the diving equipment, he followed a professional diver into the water to observe the king crabs under the water.

First came to the 30-meter-deep seabed, where the sedimentary geology is, and the king crabs are kept in large crab cages.

These crab pots are the kind of big crab pots that specialize in catching king crabs, and each contains ten adult king crabs.

The first thing Qin Feng saw was the golden king crab. Perhaps the waters where this kind of king crab lives are very deep, reaching 1000 meters. Therefore, the golden king crab in the crab cage is almost dead, and the remaining one or two are also dead. Dying.

The second crab cage I saw was the blue king crab. Compared with the golden king crab, the blue king crab is better.

Sensing people swimming over, the other two crawled around healthily, and then hid in the corner.

Five of the remaining eight died, and the other three were almost cold.

The red king crab really has the best expression, and half of them are alive.

However, these crabs came down from Qin Lei a week ago. They are different from those at a depth of 80 meters. Those are the highest batch of crabs, and they have survived in this water for 36 days.

Then he watched with the divers all the way until he swam to the deepest water of 100 meters.

Along the way, Qin Feng not only observed the condition of the king crab, but also found that Qin Lei's geographical location seems to be very good, no matter how deep the water is, there is a flat sandy land.

In the future, if they really breed, the breeding cabin will be convenient to put in.

However, Qin Feng has no idea what the breeding cabin will be like. He thinks it should be like a purse seine. If it is made into a breeding cabin like a crab cage, it will be quite troublesome when the king crab can be caught in the future.

But he also supports Qin Lei's breeding of king crabs.

In the next period of time, he only needs to release all the bigeye tuna in the breeding space to start the breeding function of the aquarium for a year.

With the degree to which king crabs can grow, it is estimated that they will flood his aquarium soon.

In this way, he does not need to go to the far sea to pretend to catch king crabs every year, but can directly put the king crabs in the farm.

Thinking of this, Qin Feng swam back to the surface and returned to the boat.

"Qin Lei, I think breeding king crabs should be fine. What you need to study now is how to make a large seine net. The opening must be on the water surface. If it is a breeding cabin like a crab cage, it will be fine for both feeding and fishing. Very troublesome."

Qin Lei sighed softly after hearing the words: "Yes, that's why I thought that the shallower the king crab farming depth, the better, and the cost of making our seine nets can be greatly reduced."

Qin Feng didn't care about the cost: "The cost is not a problem. I found that the shipwreck made a lot of money this time. At that time, it would be a big deal to invest more. If our farm is successful, we can easily make a lot of money in the future." Take the money."

There will definitely be a lot of king crabs that will be sold in the aquarium. Even if the cost is high in the early stage, it can be earned back quickly. After all, the consumption of domestic king crabs is too exaggerated, and the price is high.

If they breed successfully, the price of domestic king crabs may drop a lot in the future, which is good news for foodies.

For Qin Feng and the others, the price cut may not be bad news.

After all, the price of king crab is too high. If it is lowered, people who are reluctant to buy it may also buy it during the holidays, which can increase sales in disguise.

Hearing that Qin Feng was willing to give full support, Qin Lei was overjoyed and at the same time his worries were relieved a lot.

In this case, he may continue to increase the depth to see the inventory of king crabs.
