The list of recommendation votes is urgent, please ask for a recommendation ticket, brothers and sisters, please vote for a recommendation ticket after reading it, thanks for the shell. ****

When the Dungeness crabs arrived, the busiest person was Professor Saunders. He was responsible for this batch of precious crabs. You must know that this was 340,000 Canadian dollars. If the breeding was successful, it would be 3.4 million Canadian dollars or even three Fourteen million Canadian dollars!

Qin Shiou originally just wanted Sanders to make a name for himself. He didn't expect the old professor to really solve this problem—to turn the special treasures of the North Pacific into common catches in the North Atlantic.

But Sanders didn't think so. After he was assigned by Qin Shiou, he took this issue seriously. In addition to studying the carapace of the giant black cover worm, he spent other time thinking about the breeding of Dungeness crabs in the North Atlantic with relevant experts.

For a long time, the problem encountered by the Dungeness crab research team is that they do not know why this crab cannot survive in the North Atlantic Ocean. They have considered related factors such as light, pH, temperature, food and water quality, and even studied the differences in trace elements in different sea areas. Still haven't found the reason.

As the saying goes, prescribe the right medicine to the case, so that the symptoms can't be found, even if you are a master of Chinese medicine, you can't prescribe medicine, right?

Saunders can only carry out conservative farming. Through some related project research teams, he has obtained a new farming method, which is the new technology of "engineered farming system" to breed Dungeness crabs.

In the past week, a transportation company sent a large number of composite material partitions, and a Weir construction team dug dozens of ponds on the shore beach. After a lot of work, a breeding farm was built.

The ponds were excavated to a depth of 2 meters and separated into tanks about 20 meters long and 10 meters wide with composite partitions. Female crabs and crab seedlings escaped into these ponds.

Qin Shiou was full of curiosity. After the Dungeness crabs were delivered, they were placed on the sandy beaches around these ponds according to Sanders' instructions. The water in them was pumped from the transport ship.

The reason why the freight is so expensive is because the transport ship does not only transport Dungeness crabs. There is still a lot of seawater on it, otherwise the Dungeness crabs would have died long ago after being transported all the way out of the water.

Generally, after the transport ship arrives at the destination, the water inside will be released. Without Dungeness crabs, the seawater inside will be worthless. But Sanders didn't let them loose. Instead, it was transferred to these ponds.

Seeing Qin Shiou's curiosity, Saunders explained: ", do you know about the engineered farming system? This time I used the circulating micro-water flow farming technology in this technology, and adopted a gradual adaptation method to let Dungeness crabs adapt to ours. environment."

All the ponds add up to about four to five hundred acres.

Arranged along the coast, mainly at Mr Ross Fishing Ground.

Dozens of ponds are mainly divided into 3 areas, one side is the 100-mu water source primary purification area, the other side is the 150-mu water source secondary purification area, and there is a 50-mu main water source purification area between the two water source purification areas. In the breeding area, there are hundreds of water tanks in total, and oxygen-increasing discharge outlets are installed under each water tank.

Looking at these sinks, Qin Shiou couldn't help but be speechless: "Your investment is big enough. How much does it cost for so many composite partitions and so many oxygen generators?"

As he said that, he suddenly became vigilant: "Damn it. Professor, where did you get the research funding?"

Sanders said firmly: "These are all rented by me. If this technology is useful, then we can buy these equipment. If it is not useful, we will return them."

Qin Shiou nodded. But then I felt something was wrong: "I'm asking where did you get the research funding from?"

Sanders said slowly: "Of course it was approved by you."

Qin Shiou suddenly went crazy: "What do you mean? When did I give you instructions to buy these devices?"

Sanders said: "This is not bought. It is leased. And, when you hired me. Didn't you give me a checkbook, can you use the funds directly for research?"

"Well, I gave you the right to use the research funds at will. But - I don't care whether you bought it or rented it, I just want to ask how much it costs?" Qin Shiou's egg hurts, and Sanders looks like He is an intellectual and honest person, but why is he always cheating people?

Sanders said: "It's not much money, just fifty thousand dollars."

Qin Shiou nodded. It was true that there was not much money, so let him take care of it.

"Fifty thousand yuan, this is a week's rent." The old professor then added.

Qin Shiou immediately frowned: "It's only 200,000 yuan a month? I bought so many crabs, and it only cost 300,000 yuan!"

The old professor persuaded tirelessly: "Foresight, you have to take a long-term view. Why is your structure so small? Yes, the investment money is a bit too much now, but if it is done, it will be ten times or even hundreds of times income!"

Qin Shiou is going crazy, how dare you laugh at my pattern? This batch of crabs will definitely survive, even without this so-called new technology, he can guarantee that the Dungeness crabs will survive in the North Atlantic. So, if that's the case, why waste money?

Professor Saunders thought that Qin Shiou was concerned about money, so he further explained: "Don't think that this breeding system can only raise Dungeness crabs, in fact, it can also complete symbiotic farming."

"Look at these seawater purification areas, they can be used to raise precious seafood at will, such as sea cucumbers, conger eels, lobsters, etc. And in this kind of place, the growth rate of marine organisms is faster than in the ocean, and the meat quality is also better. better!"

The most important part of this breeding system is the 50-acre main breeding area in the middle. The water used in the breeding area is seawater transported from the North Pacific Ocean. All the Dungeness crabs are put in it, densely crowded.

Qin Shiou was worried that these Dungeness crabs would be squeezed to death inside. Sanders shrugged and said, "Dumbend crabs don't need a lot of space, what they need is enough oxygen, and I exhaust oxygen through aeration equipment in the main breeding area. , In addition, the pumps are used to speed up the flow of seawater between the main breeding area and the purification area, which can ensure the survival rate of Dungeness crabs."

Later, Sanders introduced that after studying Dungeness crabs, a research team at the University of Toronto believes that the reason why Dungeness crabs cannot survive when they leave the North Pacific Ocean and enter the North Atlantic Ocean may be related to the oxygen content of the two waters.

As we all know, the lungs of crabs are under the carapace, and they obtain oxygen by filtering seawater. The way they obtain oxygen may be different from ordinary crabs. Once the oxygen content of seawater is lower than a certain critical point, they cannot absorb enough oxygen, resulting in It died in large numbers.

The oxygen content of seawater in the North Atlantic Ocean is lower than that in the North Pacific Ocean, which may be one of the reasons restricting the survival of Dungeness crabs. Sanders started from this point to strengthen the ability of Dungeness crabs to absorb oxygen in seawater, so that they can adapt worse living environment. (to be continued)
