1983 Small Island, Starting From a Large Farmer Chapter 499

 Cultivation of shrimp seedlings and cultivating high-quality shrimp seedlings are two completely different concepts, just like asking students to study and cultivating excellent students.

There are a lot of live shrimps in the two ponds, but after Li Duoyu checked them, he found that there were really not many that were suitable as broodstock.

 First of all, most of the shrimps were screened out based on their size. There were really not many usable broodstock left. Li Duoyu simply counted and found that there were less than fifty pairs.

 For Li Duoyu, this is not enough. At least there must be more than a thousand pairs of broodstock.

Most of the species of sea shrimp in these two ponds are Chinese prawns, which are our local prawns, also known as "Qingdao prawns".

 The male shrimps of this kind of shrimp are a bit yellower in color, so fishermen often call them “yellow shrimps”.

Adult individuals can reach a maximum length of about 15 centimeters and weigh about 40 grams. A dozen of them weigh one pound.

Female shrimps are a bit greener in color and are also called "big green shrimps" locally. They are much larger than male shrimps. The largest individual can even reach nearly 20 centimeters and weigh about 90 grams. They are truly giant shrimps.

 In his previous life, Li Duoyu could hardly buy local shrimps in the wet market. All the shrimps were imported vannamei shrimps.

 Actually, it's not just shrimp farmers who worship foreigners. Li Duoyu once heard this from farmers on the island.

93 was the darkest year for shrimp farmers in Asia. At that time, a virus called "white spot syndrome" broke out.

 This directly caused the shrimp farming industry across Asia to plummet to the bottom, and countless farmers lost their harvest that year.

This is a very scary shrimp disease. Infected shrimps will reduce or even stop eating, white spots will appear on the head and breast carapace, and the body color of some diseased shrimps will turn red or fade.

 2 to 3 days after the onset of the disease, and within a week at most, the entire pond of shrimp will be completely wiped out, and there are no specific drugs to treat it.

Once you get sick, all you can do is clean the pond, and it is this terrible shrimp disease that makes shrimp farmers no longer dare to try to raise shrimp easily.

At exactly this time, a type of white shrimp named Penaeus vannamei called specific pathogen-free (SPF) suddenly emerged and quickly occupied the market.

 In layman's terms, it is a vaccinated shrimp. At this time, P. vannamei will not be easily infected with the white spot disease.

 This has also caused the vast majority of farmers to abandon Chinese shrimp and switch to raising white shrimp from Vannamei.

As far as breeding is concerned, Penaeus vannamei, which has indeed been working hard to upgrade, is definitely much easier to raise than Penaeus vannamei.

 But in terms of taste, Li Duoyu thinks that Chinese prawns are more delicious than vannamei prawns, otherwise there would not have been the incident of Qingdao prawns costing 38 yuan each.

 But for big shrimp eaters, even in 2015, 38 yuan for real secaught Qingdao prawns was not expensive as long as they were up to standard.

 Because six or seven of them are almost a pound, and wild secaught prawns of such size are really rare.

If it were alive, Li Duoyu would definitely not be willing to sell it to others to eat. He would definitely catch the broodstock for breeding.

Li Duoyu remembers clearly that wild prawns caught in the sea are very expensive here on Dandan Island.

And because they are afraid of rip-offs, they generally do not sell them to ordinary tourists, but to fishmongers who specialize in purchasing them.

Just as Li Duoyu was classifying the Chinese prawns again, his uncle Chen Dongqing asked: "Duoyu, I remember that these prawns only spawn and reproduce in April and May. If you catch them at this time, is it too early?" ”

Li Duoyu smiled: "No, if you raise more animals at this time, you might be able to find out early whether these objects have any specific diseases. And as long as the shrimp eyes are cut off and the breeding temperature is raised, breeding can be achieved." Spawning is ahead of schedule.”

Chen Dongqing was a little surprised. He could understand the increase in water temperature. After all, in April and May, the sea water generally heated up.

 But when the eyes of the shrimp were cut off, he was a little confused. "Why should the eyes of the shrimp be cut off?"

Li Duoyu frowned and accidentally mentioned some core technologies again, so he had to continue to pretend to be stupid and said:

“I'm not very sure, but the breeding experts on Hong Kong Island said that after the eyes are cut off and the female shrimp becomes blind, it will be less selective when it comes to finding a partner.”

 Chen Dongqing frowned. It was 100% not what Duoyu said. It was easier to find a partner if you were blind.

“What else did they say besides this?”

Li Duoyu thought for a while and replied: "The rest, what they said is too professional, I can't understand it. It seems like some X gland, destroying some organ that suppresses hormones."

 After hearing this, Chen Dongqing suddenly realized that he remembered that he had seen an article like this in a Dutch fishery magazine many years ago.

 When the breeding environment of farmed broodstock is not ideal, there is an organ in the shrimp handle that releases growth-inhibiting hormones.

 Let the female shrimp delay growth and development, waiting for a better environment, and then stop releasing this hormone.

 As long as this thing is destroyed, the female shrimp will not be restrained, and will quickly mate and lay eggs under the control of the urge to reproduce.

Chen Dongqing thought it was a theory, so he didn't pay attention to it. Unexpectedly, it was actually put into practice on Hong Kong Island.

 That proved to be effective. Chen Dongqing said quickly: "Duoyu, you have to keep this technology a secret. Not many people in the country know about this technology."

Li Duoyu pretended to be surprised: "This technology is so powerful. I thought what they were willing to tell me must not be confidential."

Chen Dongqing was a little jealous. He looked at his nephew up and down. His face didn't look like a good person, but why were everyone so nice to him.

 When he went to an island country, others taught him eel farming techniques. This time when he went to Hong Kong Island, others taught him such core techniques.

Could it be that some people are just lucky? Chen Dongqing couldn't help but sigh. Thinking about it carefully, Li Duoyu's luck seems to have been very good since he was a child.

“By the way, how to cut the eyes of shrimps? Do the breeding experts in Hong Kong have any demonstrations for you?”

"some."

Chen Dongqing said excitedly: "Then show me how to operate it and let me learn from it."

Li Duoyu smiled and rubbed his fingers: "If you want to learn, you can. The tuition fee must be paid first."

Chen Dongqing originally wanted to scold Ganniang, but thinking about Li Duoyu's mother-in-law, she was his sister, so it turned into scolding his sister.

So, he changed his words and cursed: "Get out of here, sir, and show me how to operate it quickly. I might be able to help you improve it."

Li Duoyu half-squinted his eyes. In fact, the shrimp eyes were not cut with scissors, but burned with high temperature.

 In previous lives, when people cut shrimp eyes, they used pliers that were very similar to the hemostats used by doctors for sutures.

 In this era, such pliers are not easy to buy, and they are definitely not available from supply and marketing cooperatives.

 Fortunately, Li Duoyu was familiar with Zhang Defa's family. After a brief greeting, he got the hemostatic forceps from the health station.

In addition to the hemostatic forceps, Li Duoyu also brought an alcohol lamp.

 After arriving at the eel factory, Li Duoyu lit the alcohol lamp, and then placed the head of the hemostat on the flame of the lamp to burn it.

  Immediately afterwards, a lucky female shrimp was fished out of the pond.

 It is actually very simple to judge male and female shrimps, just look at their first pair of shrimp legs.

 The one with nothing between the first pair of shrimp legs is a female shrimp. If there are two small sticks, it is a male shrimp.

Of course, some fishermen can also judge by color and body size. The first pair of shrimp legs Li Duoyu caught did not have small sticks.

Li Duoyu neatly grabbed the whole shrimp, then picked up the red-hot hemostats and pinched one of the shrimp's eyes.

As a slight white smoke rose, the shrimp's eyes were cut off by the red-hot hemostat instead of being cut off.

This method can not only seal the wound with high temperature, but also greatly reduce the infection rate of the shrimp, thus improving the survival rate of these broodstock.

Li Duoyu has also heard that ruthless farmers will cut off both eyes of female shrimps. In that case.

 Female shrimps cannot suppress hormones and will molt very quickly, then mature and become completely transformed into reproductive machines.

 Just by cutting off both eyes, the probability of death of the female shrimp will increase exponentially. Unless there are special circumstances, no farmer is willing to take this risk.

 After all, most broodstock are imported and are very expensive. Even broodstock bred in domestic shrimp farms are not necessarily cheap. Chen Dongqing, who was watching from the sidelines, frowned the whole time. Logically speaking, his nephew was also a newbie.

 But after this set of operations, it feels smooth and smooth, giving people a sense of dissonance, as if it has been done frequently before.

 In fact, this feeling of dissonance has been present for a long time, since the first time his nephew came to see him at the Fisheries Research Institute.

 Chen Dongqing has always felt that there is something wrong with this nephew and that he is a bit too smart.

He gave a thumbs up and couldn't help but say: "You can become a doctor with your skills."

 Li Duoyu smiled and said: "How is it possible?"

My uncle continued: "By the way, there is good news that I almost forgot to tell you. The cooperation between the institute and your company can probably continue again."

 Li Duoyu was a little surprised: "How can I say it? Didn't it stop immediately last year? Why did it start again this year?"

 The uncle looked around and said in the novel:

"I also heard from people that Zhang Xianxian, who has always been at odds with us, seems to have been in bad luck recently. Not only was he criticized by the top leaders in the county, but as far as I know, he had to write a "Why? Termination of Fisheries Research Institute and Minlong Fisheries Cooperation" report, and in the past two days, I was called to the city for a meeting."

"I also heard what Director Zhang said. If he fails to give a satisfactory answer to the superiors on this matter, he is likely to be transferred out."

Li Duoyu snorted coldly: "You should get rid of this kind of person for being a foreigner. He uses chicken feathers as arrows all day long to make everyone crazy."

Uncle Chen Dongqing looked at Li Duoyu with a smile: "There are also rumors in the county now that someone happened to be on a business trip with the big boss. As soon as he left, Zhang was called in for a talk. What a coincidence. "

Li Duoyu looked confused:

“It's none of my business. I don't have any merits. The only thing I'm really good about is that I don't like to talk behind my back. If I jump like him, I guess the organization has already targeted him.”

However, Li Duoyu was really right this time, and the matter was not entirely related to him. It was one thing for Zhang Xian to write a report.

Being called to the city for a talk is another matter, related to the resurgence of smuggling last year and the rise of smuggling cases in the past two years.

Brother-in-law Chen Dongqing stayed at the eel factory for almost a whole morning. After having lunch, he returned to the county town.

He planned to go back and look through the magazines to see if there were any reports or introductions comparable to shrimp eye-cutting.

Li Duoyu used the loudspeaker in the village to shout: "Hello everyone, villagers. I am the village director Li Duoyu. Please listen carefully. Minlong Company is planning to purchase prawns. As long as they are large, they must It's alive and jumping around."

 When the villagers on Dandan Island heard Li Duoyu's broadcast, they all dropped what they were doing, because every time Li Duoyu personally broadcasts, there is 100% chance of a big money-making project.

There were a few children at the pier who were particularly noisy. Lao Lu, who had just returned from fishing, said fiercely on the spot: "I'll throw you into the sea if I make any more noise. Listen carefully to the village director's broadcast."

Li Duoyu said at the end, "Everyone, please note that the price of live prawns is five horns."

 After hearing the price, Lao Lu slapped his thigh angrily and couldn't help but want to scold himself: "What a bastard."

Today he caught a lot of prawns with his net, but because he didn't bring a bucket of live water, he put all the prawns in the ice cabin.

Although the price of chilled shrimp is also very high, compared with the purchase price of Li Duoyu, it is a full four to five times lower.

The Zhao brothers, who were originally posting on the Internet today, immediately opened their eyes after listening to Li Duoyu's broadcast.

Since catching eel fry, the two brothers have never made much money. Now the daily fish catch is only five or six yuan, which is very boring.

 The two brothers discovered that Li Duoyu was really their lucky star, and they were good at acquiring everything.

Whether it is shrimp fry, cloves, or the giant shrimps they are catching now, they used to catch them all the time, and the two brothers often caught extra large shrimps on the tidal flats.

 The quantity is a bit small, and the price has always been lowered by the profiteer fishmonger Mr. Mi, so he didn't go out of his way to catch them. Now they finally have the opportunity.

Since the purchase of green crab seedlings, the two brothers now have many cages. If the two brothers add up, they have more than fifty cages.

  If you can catch twenty large shrimps that meet the standard a day, it will cost you ten yuan. Plus other fish catches, you can earn a minimum of twenty yuan a day.

 In a month, you can earn 600 yuan. Even if the two people share it equally, each person will earn 300 yuan a month.

And the two brothers are confident that they can catch at least thirty or forty prawns that meet the standard by closing the ground cage twice a day.

Although the two have a bad reputation on Dandan Island, since the two brothers cooperated, their wallets have obviously increased.

●From cloves, eel fry, and this time live shrimp, they have collected a lot of money.

To be honest, if the two brothers had not separated at first, now that they have pooled their money together, they would definitely become the thirteenth thousand-yuan household on the island.

And they have plans to start raising kelp directly with Li Duoyu by the end of this year after saving money in the first half of the year, and strive to have a scale of 50 acres.

Zhao Dahai had a chat with Li Duoyu years ago, and he still remembers what Li Duoyu said.

As long as you have money, you are not afraid of not having a woman. If you still don't have a woman, it proves that you don't have enough money.

This is indeed true. After making money from him, Widow Chen still wanted to come back to him, and even planned to give him a baby.

Zhao Dahai has no backbone in his life. Only that time, he slapped the woman hard and cursed: "Get out."

Zhao Erniu said: "Sure enough, there is still a way to make money by hanging out with Brother Yu."

Zhao Dahai couldn't help but smoke a cigarette and said with emotion: "If we had hung out with Brother Yu earlier, we might have been a household worth ten thousand yuan by now."

Zhao Erniu smiled and said: "Brother, it's almost time. As long as we make money from the prawns this time, we will raise kelp. When the kelp is harvested next year, the two of us may be able to become a household worth ten thousand yuan."

 Many fishermen were very excited when they heard that they were going to catch prawns, but there was one person in the village who was never happy.

Especially after learning that the person making the broadcast was the village director, his face became even more ugly, and this person was the village party secretary who was transferred to Xiasha Village. In terms of power, he was indeed the most powerful.

 But almost everyone in the village disliked him, and only a few village committee members were willing to spend a few words with him.

It seems as if he has a grudge against the whole village by coming here to serve.

As a village party secretary, he does not even have the right to use the loudspeaker in the village, because the loudspeaker is in the eel factory owned by the village director.

The eel factory is currently a relatively confidential place, and ordinary people are not allowed to enter.

He did have the right to move the loudspeaker out, but after it was moved out, there was no electricity in the village, and he couldn't use it.

He also went to the wind turbine to take a look and wanted to know more about the situation. As a result, the staff there ignored him at all, and the rank he picked out was higher than his.

It made him feel like a clown. Although he was the village party secretary, he was just like air and had no sense of existence.

 In fact, he knew it was a trap from the first day he was assigned to Dandan Island, but there was nothing he could do about it.

The county magistrate Zhang said that he would be transferred back after he had been tempered and the tough folk customs in Xiasha Village had been corrected.

 It's hard work!

  Correct the devil!

Although he has only been on Dandan Island for ten days, every day is very difficult, even worse than being in jail.

The most hateful thing is that Li Duoyu, who has obviously returned to the island, came to see him at least, even to express condolences to the comrades who just took office, but in the end he just pretended not to know.

Near the pier, a young comrade was chewing dried Balang fish with one hand and drinking beer with the other. He couldn't help but curse:

 “Fuck your uncle's Li Duoyu.”

 “Fuck your uncle Li Duoyu.”

At this moment, a voice echoed: "Well said, I finally found a comrade. I also hate that Li Duoyu very much."

The young comrade sitting on the rock was stunned for a moment, looking at the young man who was similar to himself in front of him. He always felt a little familiar, as if he had seen him somewhere. (End of chapter)
