To be honest, regardless of whether Qi Zheng will regret his big words in the future, Academician Zhou of the Institute of Oceanography of the Chinese Academy of Sciences is still happy to see Jiagu's willingness to open more exploration in marine aquaculture.

After all, although China is the world's largest aquaculture country, marine fish farming is China's shortcoming. Among them, deep-sea aquaculture is the shortcoming of the shortcomings.

At present, China's marine aquaculture is mainly concentrated in tidal flats, harbors and shallow waters outside the bay - if you look down on China's coast from satellite photos, in many bays, you can see countless cages arranged in a straight line, wooden sidewalks, countless boats, houses and villages floating on the sea, like a huge "marine ranch".

Although spectacular, the excessive development of this kind of near-shore marine aquaculture has made the carrying capacity of coastal resources and environment reach or close to the upper limit, and the water quality of some bays in some areas is eutrophicated, there are many sediments, and biological pollution is more serious.

Offshore aquaculture is beginning to shrink and the recovery of fishery resources through the stocking of fish fry, the establishment of a moratorium and the fight against illegal fishing has had limited results, so it is imperative that the marine aquaculture industry move to the deep seas.

Agricultural and animal husbandry giants like Jiagu should not crowd the offshore development of fisheries, so they should also be encouraged and supported.

Therefore, after Qi Zheng casually asked Academician Zhou if there were any good project recommendations, he really had some ideas.

"Qi Dong, have you ever heard of the concept of 'Yellow Sea Cold Water Mass'?"

"The cold water mass of the Yellow Sea?" Qi Zheng blinked, but felt a little familiar.

Seeing that Qi Zheng probably didn't know much about it, Academician Zhou introduced it.

"In the deep and bottom of the depression in the central part of the Yellow Sea, there is a water body with an area of about 130,000 square kilometers and a volume of about 500 billion cubic meters, which is called the 'Yellow Sea Cold Water Mass'. ”

"It is a body of water with a large temperature difference and a small salt difference, and is mainly characterized by low temperatures, which only exists in summer and autumn. It is unique in that the 'Yellow Sea Cold Water Mass' has a summer bottom water temperature of 4.6-9.3°C, which can be used to breed deep-sea cold-water fish that prefer low temperatures;"

"Second, the thermocline of the oceans (i.e., the thin layer of water that drops sharply between the upper thin warm water layer and the lower thick cold water layer) is usually located about 100-200 m below the sea surface, while the thermocline of the Yellow Sea cold water mass is located at about 20-30 m, which makes it possible to use this cryogenic seawater for aquaculture in situ;"

"In addition, years of investigation have shown that the dissolved oxygen in the water near the bottom of the Yellow Sea cold water mass is not less than 5 mgL, and other water quality indicators also meet the water quality standards for farmed cold-water fish......

After introducing the "Yellow Sea Cold Water Mass" in more detail, looking at Qi Zheng's thoughtful expression, Academician Zhou smiled: "Qi Dong, you should know that China's northern sea is located in the north temperate zone, and for a long time, the production of high-quality and high-priced marine cold-water fish has always been a pain in China's marine aquaculture. ”

"For example, salmon, a cold-water fish that is most suitable for growing in waters between 16 °C and 18 °C, is because China lacks a low-temperature sea area suitable for its perennial growth, so we can only look at ......the ocean and sigh."

In an instant, the memory in Qi Zheng's mind was excavated - another seven or eight years, there was a high-profile announcement in the news that "we are finally expected to eat our own salmon at our doorstep", which seems to be related to the "Yellow Sea cold water mass".

Qi Zhengmo rubbed his chin and felt a little interesting.

Although he doesn't have much relevant information in his memory, since the news is so "swearing", it at least means that the development of the "Yellow Sea Cold Water Mass" has been proven feasible.

And, salmon, too, it's a bit of a head.

In the Chinese context, the so-called "real salmon" actually refers to the Atlantic salmon of the salmonid family. Its meat is delicate and delicious, with high nutritional value, and can be eaten directly and can be used for cooking, which is very popular in European and American countries.

However, Atlantic salmon has extremely strict requirements for the living environment, and the number of Atlantic salmon cultivated in China is difficult to meet the domestic market demand, and a large number of imports from abroad are required every year.

Many people's understanding of salmon in China starts with sashimi. Well, although what they eat, it is quite possible that it is domestic rainbow trout.

Qi Zheng has never been interested in sashimi, but it does not prevent him from knowing that the market size of salmon is large.

- Depending on the sea area and water depth, the aquaculture facilities and management models applied may be completely different. For example, in the deep sea with a water depth of more than 40 meters, it is necessary to configure large-scale breeding platforms such as mobile ships and liftable farms, and at the same time, there are high requirements for comprehensive support services such as fishing, processing, material transportation, and system maintenance. Only by ensuring a stable return on the breeding of the dominant species can this high-input aquaculture production be successful.

The most successful offshore aquaculture industry in the world is salmon farming, which is a 100 billion market. Among the aquaculture companies, the one that can achieve a market value of more than 10 billion US dollars is the largest Norwegian aquaculture company that farms salmon, Meiwei.

Qi Zheng was moved in his heart and asked, "So, Academician Zhou is also involved in the research of developing the 'Yellow Sea Cold Water Mass'?"

Academician Zhou shook his head: "No, in fact, I don't have a deep study of it, but I can recommend someone to Jiagu." ”

......

Professor Dong of the National Ocean University boarded a helicopter to Pishan Island.

Being able to sail in a helicopter is a rather rare experience, even for a professor at a major university – it's a lot of money.

But Professor Dong was half nervous and half excited, not because of the helicopter, but because of Jiagu's intention to invite him.

As early as last year, his team aimed at the "Yellow Sea cold water mass", put forward the idea of using the Yellow Sea cold water mass resources to cultivate high-quality salmon trout (mainly salmon), and began a series of exploration of salmon farming technology in the Yellow Sea cold water group.

Salmon is a cold-water fish that is farmed in warm waters, and there is no precedent for success in the world. If the summer cold water resources of the Yellow Sea cold water mass can be used to carry out cold-water fish farming, this is not only a new breakthrough in China, but also the first in the world!

But "first" means to be completely on your own.

As the technical "helmsman" of this vision, Professor Dong understands how difficult it is to solve this problem that plagues China's marine aquaculture industry.

Everyone knows that the expansion of our country's aquaculture waters from offshore to deep sea is the only way for the sustainable development of the marine aquaculture industry, but the word "risk" cannot be avoided in the process of expansion.

The same is true for the development of the "Yellow Sea Cold Water Mass".

The "Yellow Sea Cold Water Mass" is far from the coast, which is susceptible to meteorological disasters such as typhoons, and the second is that huge sharks are cruising near the sea...... In order to avoid high summer temperatures, prevent shark attacks, and withstand strong winds and waves, Professor Dong's team needed a new set of breeding equipment and breeding models.

- This means that you need to invest a lot of money!

He has been promoting the "Yellow Sea Cold Water Group Green and Efficient Fish Farming Project" to the Shandong Provincial Department of Oceans and Fisheries, hoping to include this project in the provincial key research project of marine development in order to get more abundant financial support.

The Lu provincial government has certain intentions, but so far, it is only intentions, and it is difficult to say how many resources it can get.

So, on the other hand, he also has his eyes on aquatic enterprises.

In order to establish a deep-sea aquaculture model with land-sea relay and stable supply to the market, it is also inseparable from the support of enterprises related to the industrial chain.

However, I conducted research in the laboratory and went to sea on a research ship to measure the water depth, temperature, dissolved oxygen, and flow rate...... These professors can be easily reached. But dealing with companies that "don't see rabbits, don't scatter eagles" really gave him a headache.

At the end of the day, it's too much investment. Until there is clear support from the government, not many companies can afford to invest in the research of the entire project.

Unexpectedly, his old friend Academician Zhou sent him great news - Jia Gu was interested in using the "Yellow Sea Cold Water Mass" salmon breeding project.

That's Jiagu! It almost made Professor Dong laugh out loud.

Even if Academician Zhou did not hint at Jiagu's wealth on the phone, Professor Dong should also do his best to turn Jiagu's "interest" into "strong support" - just inviting himself to negotiate, he will have the treatment of taking a helicopter, so if Jiagu vigorously supports his research, what kind of resources will he get?

Professor Dong came with the attitude of attending an extremely important interview. Of course, in a way, he really felt that it would be a serious interview.

Jiagu is rich, but money does not fall from the sky. If he wants the family to pay willingly, he has to show eighteen kinds of martial arts. Fortunately, with Academician Zhou, who has a good relationship with Jiagu, beating the drum on the side, he still has some confidence.

However, the experience was destined to be completely unexpected.

......

Qi Zheng looked at Professor Dong in front of him, and skipped the sorted out memories in his heart - well, that's right, in the news about "salmon raised in the cold water of the Yellow Sea" in later generations, Professor Dong's name runs throughout.

"Professor Dong, how confident do you have about using the cold water mass of the Yellow Sea to engage in salmon farming?" After confirming his eyes, Qi Zheng got straight to the point.

"I have full confidence. Professor Dong naturally did not hesitate.

As he thought, during the negotiation process, his friend Academician Zhou was also accompanied by him, but mainly to see his own performance.

Professor Dong has dealt with many enterprises, and he knows that the first thing to talk about when promoting projects to enterprises is not how advanced the technology is and how powerful the team is, but to talk to them about the benefits, which is commonly known as "being able to draw cakes".

"The Yellow Sea cold water mass has 500 billion cubic meters of water, and 1% of it is 5 billion cubic meters for aquaculture. According to the calculation of raising one fish per 10 cubic meters of water, 500 million fish can be raised, and according to the calculation of 4 kilograms of fish per fish, it is 2 billion kilograms, and even if the market price is calculated at 40 yuan per kilogram, the economic benefit is as high as 80 billion yuan......"

Professor Dong glanced at Qi Zheng, and saw that he kept smiling, and his expression remained unchanged at all, and he knew that Qi Zheng didn't care about the "cake" he painted at all.

Thinking about it, if you can make such a big career, how can you easily believe in other people's "painting cakes"?

Professor Dong was a little apprehensive, remembering Jiagu's ecological philosophy, and said: "In terms of environmental protection, one of the purposes of our offshore aquaculture development is to alleviate the pollution pressure of offshore aquaculture. However, the Yellow Sea cold water mass has open space for development and good water exchange conditions, and even if the scale of offshore aquaculture development is calculated at the level of 100 billion yuan, the waste generated is far lower than the self-purification capacity of the sea area, and it will not have a significant impact on the water quality of the Yellow Sea waters......"

Qi Zheng nodded slightly, but still didn't say anything.

Seeing that Qi Zheng still had no reaction, Professor Dong could only continue: "In addition, our team has gathered more than 20 experts in physical ocean, breeding facilities, marine engineering and other disciplines, and has a certain idea of how to develop this natural 'low-temperature pasture', where to raise it, what to raise it, and how to raise it......

Finally, Qi Zheng smiled slightly, as if he had entered into thought.

Professor Dong couldn't help but glance at Academician Zhou next to him, and he just signaled to be calm.

Qi Zheng raised his head, and Professor Dong subconsciously held his breath.

"Professor Dong, I agree to launch the 'Yellow Sea Cold-Water Mass Farming of High-quality Cold-water Fish Project', which is jointly implemented by Jiagu Agriculture and Animal Husbandry and the National Ocean University. ”

Hearing this, Professor Dong smiled with relief.

Qi Zheng smiled slightly, and said unhurriedly: "In order to ensure the smooth progress of the project, we have specially equipped the R&D team with expert apartments in Lu Province, and will communicate with the government to provide perfect support in terms of funds, sea outlets, and the use of sea for aquaculture." ”

Professor Dong's smile widened.

Why did he pursue cooperation with Jiagu? On the one hand, it was because Jiagu was good enough, and on the other hand, it was this!

It is no exaggeration to say that Jiagu's influence on the government is enough to allow the project to enter the "green channel" in terms of policy support.

With funds in the left hand and policies in the right hand, if you can't make achievements anymore, you are completely incompetent.

But that's not all.

“...... The initial investment of the project is 4 billion yuan, and the planned sea area is 50,000 mu. I also hope that the National Ocean University will take the lead in designing, Jiagu Agriculture and Animal Husbandry will fund, and China Shipbuilding Group will build a large-scale aquaculture vessel or deep-sea aquaculture cage as the breeding base of the project......"

"......" Professor Dong's smile froze.

There is only one voice floating in his head - "4 billion yuan"!

Is Kaya crazy?

Obviously, I only want to verify the technical route of using the Yellow Sea cold water mass to cultivate salmon, so as to achieve a new breakthrough in deep-sea cold water fish farming, but what is Jiagu going to do? Is this to build the whole industrial chain of the Yellow Sea cold water group at one time?

He regretted that the "pie" he had just drawn was too big.

It's not that he doesn't have confidence in the project breakthrough, but when the breakthrough will be absolutely unknown; moreover, even if the technology breaks through, it doesn't mean that it has entered the practical stage, and he doesn't dare to think, where does Jiagu get so much confidence?

It stands to reason that the support given by Qi Zheng has far exceeded his best imagination, but Professor Dong was stunned and couldn't answer.

It's like he just wants to gamble on pleasure, but Jiagu is a stud, and the pressure is ......

Professor Dong turned Mu Ran's gaze to his old friend, Academician Zhou.

Academician Zhou shrugged with a slightly wry smile.

But Professor Dong magically understood what he meant - na, this is a local tyrant, rich, and capricious!

......
