1983 Small Island, Starting From a Large Farmer Chapter 606

 Chen Dongqing was quite troubled by the questions, because the shrimp disease came so suddenly, and even they didn't know the cause of the shrimp's death.

It was as if these shrimps had made an appointment and exploded during this period.

Chen Dongqing pushed up his glasses, looked at the shrimp farmers surrounding his office and shouted: "Please don't worry, we have been working hard to find the cause."

But these shrimp farmers were all anxious and said one after another: "Chief Chen, we have been hearing this for more than a week. We have invested a lot of money in raising shrimps. You have to help us find a way."

A shrimp farmer said worriedly: "A lot of shrimps die every day. If this continues, we will really lose everything."

Chen Dongqing was also very angry. Helping is a matter of love, not helping is a duty. Breeding is inherently risky. He is only a researcher, so he can just close the door and ignore them.

Unexpectedly, there were actually people who kicked their noses in their faces and shouted directly: "You gave me the shrimps, so you must be responsible to the end."

Unexpectedly, someone actually followed and shouted: "Yes, the shrimp fry are given by the research institute, so you must be responsible to the end."

After hearing this, Chen Dongqing was really angry. He slapped the table on the spot and cursed:

"Shrimp fry, did you charge me any money? When I gave you the shrimp fry, did I tell you that we are only responsible for providing shrimp fry and cannot guarantee the quality of the shrimp fry?"

The scene was silent for a long time, but someone still said: "But why are our deaths so serious, but the Minlong Shrimp Farm seems to be fine."

Chen Dongqing gritted his teeth and said: "I have a big head. Nothing has happened. The whole three shrimp ponds have suffered. This time it is a shrimp epidemic. Everyone has been affected. Besides, your management is the only one that can compare with Fujian." Longbi."

Some shrimp farmers couldn't stand it and sighed: "Why don't you scold me for getting a cheap deal? Those of you who get seedlings from the research institute for free are now better off than those of us who pick them in the wild."

"Some of us are almost half dead."

Fortunately, there are sensible people, otherwise Chen Dongqing would have a really big head, which reminded him of how high-spirited he was back then.

As soon as the summer seedlings of kelp were developed, the villagers were immediately asked to plant them. As a result, they did not dare to return to the village for two years.

Fortunately, Li Duoyu gave these shrimp fry away, otherwise he would not have made much money and would have ended up in a mess.

This kid is still stable, but Chen Dongqing has a strange feeling that Li Duoyu has known something for a long time.

It always felt like every step he took was to avoid risks as much as possible. Previously, he always felt that cultivating excellent broodstock seedlings was not that necessary.

After all, even ordinary shrimp seedlings are not much worse than his shrimp seedlings in real life. At most, they are smaller in size, but the economic benefits are still the same.

But looking at it now, it's really far-sighted, especially the laboratory that was spent a lot of money on, it was simply used for this moment.

County Fisheries Research Institute, those shrimp farmers could not get useful information and eventually left.

Director Zhang Qingyun frowned. This time the shrimp disease was not localized, but rather widespread.

This kind of shrimp disease has appeared not only in Rongcheng, but also in many places. After seeing Chen Dongqing coming, Zhang Qingyun couldn't help but ask:

"Holly, what's going on with this shrimp disease?"

Chen Dongqing shook his head.

"I have no clue at all. It is most likely caused by a new virus. The virus is currently being purified."

"Is purification something we do here?" Zhang Qingyun just came from the laboratory and found that no one was doing this.

Chen Dongqing smiled awkwardly:

"Well, it seems that the equipment in our institute has not been replaced for a long time. This work is now being carried out by Minlong. My senior brother is an expert in shrimp farming. We can only see if he has a solution."

Zhang Qingyun heard it and rolled his eyes at him: "I can't be the only one working on this equipment problem. You also have to think of a solution. Our nursery base has been separated, so we can't separate all the laboratories. "

"Director, everything is for our breeding industry. It's not like I haven't applied before. The process is too long."

Zhang Qingyun rolled his eyes and said: "Can you please turn your arm back a little? If I retire, who do you think will take this position?"

Chen Dongqing smiled and said: "How dare I think so much? You will be 100% fine for another five or six years."

Zhang Qingyun said: "If there are results from the research on shrimp diseases this time, I will try my best to get as many fish as possible to get my name signed."

"That's for sure, he doesn't want to sign it."

"Also, if there is a way, control the shrimp disease quickly. If this continues, it will probably hit the entire shrimp farming industry."

"Okay, we will work hard."

But in fact, Chen Dongqing knew very well that even if there was a solution, it was already too late.

There is a saying that Li Duoyu is right about. The most important thing in aquaculture is not how to cure diseases, but how to prevent them.

The density of aquaculture is relatively high. Once this situation occurs, it means that losses have already begun. It is just a matter of more or less.

Li Duoyu has also been working in a shrimp farm these days. This time, even he was not immune to the shrimp plague. His brother-in-law, Zhang Mingsheng, took a fishing net to fish in a shrimp pond labeled A17.

Not long after, a lot of dead shrimps were caught. Logically speaking, the heads and tails of these shrimps had been raised for more than three months.

Logically speaking, it should be about the size of 25 shrimps (25 shrimps per pound).

But these dead shrimps were obviously a little smaller, and they didn't even feel like 30 shrimps.

There were obvious white spots on the heads of the shrimps, and the entire stomach and intestines were empty, and they did not appear to be eating.

The whole shrimp head and shell feel very soft, and the shrimp head and tail will separate with just a pinch.

Brother-in-law Zhang Mingsheng said with a bitter face: "Why are more people dying today, Duoyu, do you know the reason for this?"

Li Duoyu shook his head. In fact, when he saw the dead shrimp for the first time, he already knew what kind of disease it was.

Those who engage in breeding generally call this disease leukoplakia, and once this disease occurs, it is just like the human flu and is impossible to disappear.

And the most troublesome thing for shrimp farmers is that there is no specific cure for this disease. Once the infection is severe, they can only give up and consider themselves unlucky. In serious cases, the only option is to drain the pond, that is, to get rid of all the shrimps. .

It can be said that few farmers are willing to discharge shrimps of this size into ponds.

But everyone is profit-seeking. Who wants to have all the money they have worked hard for for half a year wasted? Naturally, they can get back a little bit.

In his previous life, whenever the price of shrimp dropped sharply, he would not buy shrimp, especially those whose shells were soft to the touch and were 100% virus-containing.

In the laboratory of the shrimp farm, Teacher Lei and two other teachers from the College of Agriculture were all doing pathological analysis on the dead shrimps.

On hand, they not only had dead shrimps from Minlong Shrimp Factory, but also samples of dead shrimps from the neighboring province.

They have not had a break for several days and are conducting various virus tests on the dead shrimps.

Teacher Lin Peng said: "There is nuclear hyperplasia in the hepatopancreas."

"Hepatopancreatic white turbidity"

"In the bacterial category, no typical pathogenic bacteria were isolated."

Lei Youshan frowned, looking tired. He had just decided to study shrimps, but unexpectedly, he encountered shrimp plague.

This was really a big challenge for him, and at this time, Chen Dongqing also returned to the laboratory and brought back some useful news. "I have collected some information in the past two days. This disease started to break out from Ludao Island, and it is also found in the neighboring province. A shrimp farmer from Ludao Island said that last year, the shrimps he raised often showed symptoms of death."

After hearing this, Lei Youshan said: "So, it may be infected by a foreign virus. Let's study it in another direction."

Chen Dongqing nodded: "I also think this is more reasonable. This virus most likely existed last year and infected shrimp seedlings. Otherwise, there would be no such large-scale outbreak this year."

Originally, Chen Dongqing wanted to experiment with high-density breeding, but after encountering this strange virus, he stopped the project.

During this time when shrimp diseases are rampant, the entire shrimp farming industry is in a haze.

Because many shrimp farmers were afraid, they all shipped their goods in advance, causing the price of shrimps to skyrocket. Originally, the retail price of shrimps was as high as five yuan, but now it has dropped to three yuan. However, shrimp farmers' shipping prices are even lower, with some It's just one dollar and a half.

And the fishermen who originally made money by catching shrimp have been complaining a lot these days. If these shrimp farmers do this, they can't make much money.

The purchase price of prawns is just two yuan, and the price of other sword shrimps, slippery shrimps, etc. is even lower.

News of the disease in shrimps gradually spread among the public, and even caused panic in the entire aquatic product market, causing other aquatic products to also cut prices.

In short, the entire aquatic products industry is in mourning. As long as they sell aquatic products in Rongcheng Agricultural Trade Center, no one is happy.

The fishermen on Dandan Island have also been very troubled these past two days, and the Zhao brothers quarreled with the fishmonger Lao Mi again.

"Yesterday, the pomfret cost only 2 cents, but today it's only 10 cents. Also, the price of rice fish has been 50 cents this year, but now it's only 30 cents."

Other fishermen also said: "Lao Mi, you have to be conscientious in doing business. If there are not enough fish collected on the island, you can act randomly."

Old Man Mi was also helpless: "If you think I lied to you, go to Rongcheng and see for yourself how the price of seafood has dropped recently. If I didn't take care of you, I wouldn't want to accept your fish. If I did, I wouldn't even pay for my own fish." I can't even make any money back.”

These days, the Fisheries Bureau is holding meetings every day and even invites many aquaculture experts to study the shrimp plague.

But after a week or two of research, we still couldn't find the source of the disease, and we were at a loss to do anything about this shrimp plague.

All that is known so far is that once the shrimp is infected by the unknown virus, it will lose its ability to eat.

The phenomenon of floating appears first, then sinks to the bottom and slowly dies, and the shrimps also have the habit of eating the same kind.

As long as you don't pay attention, the dead shrimp will soon be eaten by the same kind, and the infection will continue.

As soon as this disease begins and farmers don't pay attention, all the shrimp in the pond may die without the farmers knowing it.

These experts also gave this disease a very appropriate name, called "death-stealing disease."

After the meeting, these experts were at a loss to deal with the disease. Thinking that Li Duoyu still had a big order in hand, Wu Yuping called the Qixing Bay Shrimp Factory and said anxiously:

"I'm Wu Yuping from the Fisheries Bureau, is Li Duoyu here?"

Operator Chen Xiaoyan replied: "Hello, Director Wu, Director Li is at the shrimp pond. Why don't you wait a moment and I'll call him right away."

Wu Yuping frowned: "Don't worry, let him be busy first, and call me back when he is free."

"I understand, Director Wu."

Affected by this shrimp plague, Zhang Mingsheng fished out two to three hundred kilograms of dead shrimp from the shrimp pond every day.

Everyone was almost dying of anxiety, but Li Duoyu didn't seem to be in any pain or itching at all. He still ate and slept well every day.

No one dared to ask.

Although Zhou Xiaoying knew about this, at this juncture, she chose not to cause trouble and tried her best to do things well at home and take care of her children.

However, Li Duoyu is really not in a hurry, because he has more than 20 shrimp ponds, and currently only five of them have problems, covering about 100 acres.

There are still 400 acres of shrimp ponds left, and they are not suffering from this shrimp disease, and this is also related to his farming model.

The water in each shrimp pond of Li Duoyu is not connected to each other. Even if one of the ponds is infected, the virus will not easily spread to the next pond.

For farmers, this shrimp plague is 100% a disaster, but for Li Duoyu, who wants to develop "special disease-free broodstock", it is an opportunity and a large-scale experiment.

The male and female parents of these shrimp larvae cultured by Li Duoyu are originally large and relatively robust broodstock, and their resistance is naturally better than that of randomly caught sea shrimp in the wild.

Even if he was infected with shrimp plague, Li Duoyu had no intention of draining the pond and disposing of all the shrimps. He only had to catch the dead shrimps in time.

Because the shrimps he raises have relatively good immunity, not all of them will die when encountering this disease.

At least half of the shrimp will survive, and those who survive will most likely acquire immunity to the virus.

If this kind of shrimp is used as broodstock and used to breed the second generation, it is very likely to obtain shrimp larvae that are immune to the virus.

In previous lives, shrimp larvae that were immune to viruses were generally called highly resistant broodstock.

In other words, it may not necessarily grow very quickly, but it has the ability to withstand viruses. It means that it has a strong skin and is easy to maintain.

But currently Li Duoyu's shrimp seedling plan is still in its first step, and even he himself can't guarantee it.

Will these surviving live shrimps in the shrimp pond be infected again? Li Duoyu can only leave many things to Lei Youshan and the others.

Almost in the third week after the shrimp plague appeared, Lei Youshan and the others finally isolated the culprit that caused the shrimp plague.

And they discovered that the nucleocapsid of this virus was rod-shaped, so they didn't bother to name it and just called it shrimp baculovirus.

But even if they knew about the virus, Lei Youshan and Chen Dongqing found that there seemed to be nothing they could do about it.

Viruses are easy to eliminate. If the water temperature reaches above 30 degrees, the viruses will lose their activity. If the acidity reaches 50 degrees Celsius or the alkali reaches 12 degrees Celsius or above, they can be killed directly.

But all the methods that can kill the virus will also kill the shrimps, which leaves them with nothing to do.

Now, Lei Youshan finally understands how advanced Li Duoyu's ideas are, especially the breeding direction of [broodstock without special disease sources] that he mentioned is simply tailor-made for this shrimp plague.

Since we can't control the virus, we shouldn't do it. Instead, just cultivate some species of shrimp that can be immune to this disease.

During this time, Ludao Haixin Group was also holding a shareholders' meeting, and all the shareholders were smiling.

"If you don't have diamonds, don't be lazy in porcelain work. This time the shrimp plague will kill that Li Duoyu."

"He also sent so many shrimps out. If those shrimp farmers suffer heavy losses later, they will definitely find trouble with him."

"Let them refuse to buy our shrimp seedlings and buy Li Duoyu's. Free things are often the most expensive."

"Fortunately, we got these shrimp seedlings from overseas provinces, so we escaped a disaster."

"It's not that Mr. Du is capable. Without him, we might have followed Mr. Zhang's footsteps."

But in the middle of the shareholders' meeting, the person in charge of Haixin Shrimp Factory suddenly came to the conference room and followed Sun Xiangdong with an anxious expression.

Sun Xiangdong's face instantly turned ugly and he immediately suspended the January shareholders' meeting.

"Let's get here first today. I have some urgent matters to deal with." (End of Chapter)
