When the treasure crabs arrive, the busiest person is Professor Sanders. He needs to be responsible for these precious crabs. You know, this is $340000. If the feeding is successful, it is $3.4 million or even $34 million!

Qin Shiou had just asked Sanders to give his name. He didn't expect the old professor to really solve this problem - turning the specialty treasures of the North Pacific into ordinary catches in the North Atlantic.

However, Sanders didn't think so. After being appointed by Qin Shiou, he took this issue seriously. Usually, in addition to studying the crustaceans of black lid giant beetles, he spent other time thinking about the breeding of treasure crab in the North Atlantic with relevant experts.

For a long time, the problem encountered by the treasure crab research team is that they don't know why this kind of crab can't survive in the North Atlantic. They have considered relevant factors such as light, pH, temperature, food and water quality, and even studied the difference of trace elements in different sea areas, but still haven't found the reason.

As the saying goes, suit the remedy to the case, so the symptoms can't be found. Even the national hand of traditional Chinese medicine can't prescribe medicine, right?

Sanders can only carry out conservative breeding. Through some relevant project research teams, he has obtained a new breeding method, that is, the new technology of "engineering breeding system", so as to breed precious crabs.

In the past week, a transportation company sent a large number of composite diaphragms, and a Weier construction team dug dozens of ponds on the beach and built an aquaculture farm.

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

Qin Shiou was curious. After the treasure crab was delivered, it was put on the beach around these ponds according to Sanders' instructions. The water in it was extracted from the transport ship.

The reason why the freight is so expensive is that there is a lot of sea water on the transport ship in addition to transporting treasure crabs. Otherwise, treasure crabs would have died all the way out of the water.

Generally, after the transport ship arrives at the destination, the water in it will be released. Without the treasure crab, the sea water in it will be worthless. But instead of letting them drain, Sanders transferred them to these ponds.

Seeing Qin Shiou's curiosity, Sanders explained, "boss, do you know the engineering farming system? This time, I use the circulating micro flow culture technology in this technology, and adopt the way of gradual adaptation to make the treasure crab adapt to our environment. "

All the ponds add up to about four or five hundred mu, which are arranged along the coast, mainly in Mr. Ross's fishing ground.

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

Looking at these sinks, Qin Shiou couldn't help but say, "you have invested enough. How much do you get for so many composite diaphragms and so many oxygen generators?"

Then he suddenly became vigilant: "shit, Professor, where did you get the research funds?"

Sanders said, "these are all rented by me. If this technology is useful, we can buy these equipment. If it is useless, we will return them."

Qin Shiou nodded, but then he felt that there was something wrong: "where did you get the research funds?"

Sanders said slowly, "of course it's through your instructions, boss."

Qin Shiou immediately went crazy: "what do you mean? When did I give you instructions to buy these equipment? "

Sanders said, "it's not bought, it's rented. Moreover, when you hired me, didn't you give me a checkbook so that you could directly use the funds for research? "

"Well, I gave you the right to use research funds at will. But - I don't care whether you buy it or rent it. I just want to ask how much it costs? " Qin Shiou's egg hurts very much. Sanders seems to be an intellectual and honest man, but why is he always cheating?

Sanders said, "it's not much. It's only 50000 yuan."

Qin Shiou nodded. He really didn't have much money, so let him do it well.

"Fifty thousand yuan. It's a week's rent." The old professor added.

Qin Shiou suddenly blew his hair: "he's only 200000 a month? I only spent 300000 on buying so many crabs! "

The old professor tried to persuade him: "look, boss, your vision should be long-term. Why is your pattern so small? Yes, there is a lot of money invested now, but if it is successful, it will be ten times or even a hundred times the income! "

Qin Shiou is crazy. Dare you laugh at my pattern? These crabs are sure to survive. Even without this so-called new technology, he can ensure that precious crabs will survive in the North Atlantic. So, in that case, why waste money?

Professor Sanders thought Qin Shiou loved money, so he further explained: "boss, don't think this breeding system can only raise treasure crabs. In fact, it can also complete symbiotic breeding."

"You see, these seawater purification areas can be used to arbitrarily cultivate precious seafood, such as sea cucumber, sea eel, lobster and so on. Moreover, when cultured in this place, the growth rate of marine organisms is faster and the meat quality is better than that in the ocean! "

The most important part of this breeding system is the 50 mu main breeding area in the middle. The water used in the breeding area is sea water transported from the North Pacific Ocean, and all the treasure crabs are put into it, which is densely crowded.

Qin Shiou was worried that these treasure crabs would be crowded inside. Sanders shrugged and said, "treasure crabs don't need much space. They need enough oxygen. I discharge oxygen through oxygenation equipment in the main breeding area. In addition, I use water pumps to accelerate the flow of seawater between the main breeding area and the purification area, which can ensure the survival rate of treasure crabs."

Sanders later introduced that after the research on treasure crabs, a research team at the University of Toronto believes that the reason why treasure crabs can't survive after leaving the North Pacific and entering the North Atlantic may be related to the oxygen content of the two waters.

As we all know, the lungs of crabs obtain oxygen by filtering seawater under their shells. The way they obtain oxygen may be different from ordinary crabs. Once the oxygen content of seawater is lower than a critical point, they cannot absorb enough oxygen, resulting in mass death.

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