Cultivating shrimp seedlings and cultivating high-quality shrimp seedlings are two completely different concepts, just like letting students study and cultivating excellent students.

There are a lot of live shrimp in the two ponds, but after Li Duoyu checked it, there are really not many suitable for being broodstock.

First of all, the size of the shrimp was screened out, and there were really not many broodstock that could be used, Li Duoyu simply counted it, and it was less than fifty pairs.

For Li Duoyu, this is far from enough, at least ensure that there are more than 1,000 pairs of broodstock.

Most of the varieties of shrimp in these two ponds are Chinese prawns, that is, our native prawns, which are the so-called "Qingdao prawns".

In this kind of prawn, the male shrimp will be a little yellowish in color, and fishermen often call them "yellow shrimp".

Adult individuals can reach a maximum of about 15 centimeters, weigh about 40 grams, and have a pound in a dozen heads.

"What's the matter with me, I don't have any advantages as a person, but one thing is particularly good, that is, I don't like to chew my tongue behind my back, and I guess the organization has been eyeing him for a long time."

The year 93 was the darkest year for shrimp farmers in Asia, when there was an outbreak of a virus called "vitiligo syndrome".

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

After all, most of the broodstock are imported, which is very expensive, even the broodstock bred in domestic shrimp farms are not necessarily cheap.

Chen Dongqing, who was watching from the sidelines, frowned the whole time, it stands to reason that his nephew had obviously just learned.

Let the female shrimp delay their growth and development, thus waiting for a better environment, which stops the release of this hormone.

"I also heard what Director Zhang said, if he fails to give a satisfactory answer to the above, he is likely to be transferred."

Li Duoyu was a little surprised: "How to say, didn't you just stop last year, why did you start again this year." ”

In addition to the hemostat, Li Duoyu also took the alcohol lamp by the way.

Although the price of chilled shrimp is also very high, it is four or five times worse than the purchase price of Li Duoyu.

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

Li Duoyu looked confused:

After coming to the eel factory, Li Duoyu lit the alcohol lamp, and then put the tongs of the hemostat on the flame to burn.

Directly caused the shrimp farming industry in Asia to fall to the bottom, and countless farmers directly lost the harvest that year.

After hearing this, Chen Dongqing suddenly realized, and then remembered that many years ago, he had seen such an article in a fishing magazine in the Netherlands.

In fact, it is not that shrimp farmers are also engaged in foreign charm, Li Duoyu has heard from farmers on the island.

Just when Li Duoyu classified these Chinese prawns again, his brother-in-law Chen Dongqing asked: "Duoyu, I remember that these prawns only spawn and reproduce in April and May, if you catch them at this time, will it be too early?" ”

If you can catch 20 prawns a day, it will be 10 yuan, plus other catches, you can earn 20 yuan a day.

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

"I don't know very well, but the farming experts on Hong Kong Island said that after cutting off the eyes, the female shrimp is blind, and the target is not so picky."

In the previous life, Li Duoyu almost couldn't buy local prawns in the vegetable market, all of them were imported vannamei shrimp.

It's as if he came here to serve as if he had a grudge against the whole village.

Li Duoyu thought for a while and replied: "For the rest, what they said is too professional, I don't understand it, it seems that what X gland, what organ destroys hormones."

"Fuck your uncle's Li Duoyu."

In fact, from the first day he was assigned to Dandan Island, he knew that this was a pit, but he couldn't help it.

Chen Dongqing said excitedly: "Then you can show me the operation, and let me learn it well." ”

Fortunately, Li Duoyu was familiar with Zhang Defa's family, and after a brief hello, he got the hemostat from the health station.

A few years ago, Zhao Dahai talked to Li Duoyu, and until now, he still remembers what Li Duoyu said.

"Is there anything else they have to say?"

This method not only seals the wound with high temperatures, but also greatly reduces the infection rate of shrimp, thereby improving the survival rate of these broodstock.

If he lived, Li Duoyu would definitely be reluctant to sell it to others to eat, and he would 100% catch the broodstock that bred shrimp.

Chen Dongqing has always felt that this nephew is not very right, and he is a little too smart.

Judging male and female shrimp is actually very simple, just look at their first pair of shrimp legs.

It's just that the quantity is a little small, and they are always depressed by Old Man Mi, a profiteer and fishmonger, so they didn't go out of their way to catch it, and now they finally let them wait for the opportunity.

Chen Dongqing was a little jealous, he looked this nephew up and down, and his face didn't look like a good person, but everyone was so good to him.

The female shrimp will not be able to suppress hormones, and will molt very quickly, and then X matures, completely reduced to a fertility machine.

Li Duoyu snorted coldly: "If you are also transferred, this kind of person should be directly removed, and use chicken feathers as arrows all day long, making everyone jump." ”

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

"Yes."

Chen Dongqing thought it was a theory, so he didn't pay attention to it, but he didn't expect that it had already been practiced on Hong Kong Island.

Of course, there are also fishermen who can also judge by color and body size, and the first pair of shrimp feet caught by Li Duoyu does not have a small stick.

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

He plans to go back and flip through the magazines to see if there are any reports and introductions that are comparable to cutting shrimp eyes.

Zhao Dahai couldn't help but smoke a cigarette and said with emotion: "If we had messed with Brother Yu earlier, we might have been 10,000 yuan by now." ”

Between the legs of the first pair of shrimps, there is nothing, that is the female shrimp, if there are two small sticks, it is the male shrimp.

Being called to the city to talk is another incident, which is related to the resurgence of smuggling last year and the smuggling cases that have arisen in the past two years.

The female shrimp is a little greener in color, and it is also called "big green shrimp" locally, which will be much larger than the male shrimp, and the largest individual can even reach nearly 20 centimeters and weigh about 90 grams, which is a veritable prawn.

"By the way, how to cut shrimp eyes, those breeding experts on Hong Kong Island, do you have a demonstration for you?"

To be honest, if the two brothers hadn't split up at the beginning, now that the two brothers have pooled the money, they would definitely be able to become the thirteenth 10,000 yuan household on the island.

As long as you have money in hand, you are not afraid of not having a woman, and if you still don't have it, it proves that your money is not enough.

In fact, this sense of disobedience has been present for a long time, since the first time his nephew came to the Fisheries Research Institute to look for him.

In a month, you can earn 600 yuan, even if the two of you divide equally, each person will have 300 yuan per month.

This has led to the vast majority of farmers abandoning Chinese prawns in favor of whiteleg shrimp farming.

Could it be that some people's shit luck is good, 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.

As a village party secretary, he didn't even have the right to use the village loudspeaker, because the loudspeaker was in the village director's eel factory.

Li Duoyu pretended to be surprised: "This technology is so powerful, I thought that what they were willing to tell me was definitely not a confidential thing." ”

As far as aquaculture is concerned, it is true that the South American white shrimp, which has been striving to be renewed, is definitely much easier to raise than the Chinese shrimp.

Li Duoyu smiled: "No, at this time, if you raise more, maybe you can find out if these objects have any specific diseases as soon as possible, and as long as you cut off the shrimp eyes and increase the breeding temperature, you can make the breeding and spawning in advance." ”

He gave a thumbs up and couldn't help but say, "You feel like you can be a doctor with this technique." ”

So, he changed his tone and scolded: "Get out of your uncle, hurry up and show me, I may be able to help you improve." ”

Once you get sick, the only thing you can do is clear the pond, and it is also this terrible shrimp disease that makes shrimp farmers dare not try to raise shrimp easily.

After hearing this price, Lao Lu slapped his thigh angrily, and couldn't help but want to scold himself: "The girl is a bastard." ”

The two brothers found out that this Li Duoyu was really their lucky star, and they were all good at what they bought.

And Li Duoyu shouted with the loudspeaker in the village: "Villagers, hello everyone, I am Li Duoyu, the village director, please pay attention to it, Minlong Company is going to buy prawns. As long as it's big, it has to be alive, and it's the kind that can bounce."

Since the purchase of blue crab seedlings, the two brothers now have a lot of ground cages, and the two brothers together have more than 50.

Chen Dongqing wrinkled his brows, 100% not like Duoyu said, what is blind is easier to find a partner.

Li Duoyu remembers very well that here on Dandan Island, this kind of wild prawns caught in the sea is also very expensive.

But for the shrimp eater, even if it is 15 years, the real sea fishing of Qingdao prawns, as long as the size is up to standard, 38 yuan is really not expensive.

But when he cut off the shrimp eyes, he was a little confused, "Why do you want to cut off the shrimp eyes?" ”

He also went to the wind turbine to take a look, and wanted to find out about the situation, but the staff over there ignored him at all, and randomly brought out a level higher than him.

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

The most hateful thing is that Li Duoyu, obviously he has already returned to the island, so he came to see him, even if he condoled with the comrades who had just taken office, but he pretended not to know.

When he went to the island country, others taught him eel farming techniques, and this time he went to Hong Kong Island, others taught him such a core technique.

With the slight white smoke rising, the shrimp eyes were scalded off by the red-hot hemostats, not cut off.

Uncle Chen Dongqing stayed in the eel factory for almost a morning, and after lunch, he returned to the county seat.

There were a few children on the dock who were particularly noisy, and Lao Lu, who had just come back from fishing, said fiercely on the spot: "If you make any more noise, throw you into the sea, and listen to the village director's radio." ”

Especially after learning that the person who broadcast the radio was the village director, his face was quite ugly, and this person was the village party secretary who was transferred to Xiasha Village.

Zhao Erniu said with a smile: "Brother, it's almost over, as long as we make money from the prawns this time, we will raise kelp, and when the kelp harvest next year, the two of us may be able to become 10,000 yuan households." ”

Sharpen a ghost!

Correct the hell!

Although he has not been on Dandan Island for ten days, every day is very difficult, worse than being imprisoned.

After the villagers of Dandan Island heard Li Duoyu's broadcast, they all put down what they were doing, because every time Li Duoyu broadcast in person, he had 100% big projects to make money.

Brother-in-law Chen Dongqing looked at Li Duoyu with a smile: "Now there are also people in the county who are rumoring that someone happened to go on a business trip with a big leader, and as soon as the front foot left, Zhang Xianjin was called to talk. What a coincidence. ”

This is a very terrible shrimp disease, the infected shrimp will reduce or even stop feeding, white spots will appear on the cephalothorax, and the body color of some diseased shrimp will turn red or dull and fade.

Li Duoyu also heard that a ruthless farmer would cut off both eyes of the female shrimp, in that case.

When the breeding environment is not ideal, there is an organ in the shrimp stalk, which will release hormones that inhibit growth.

Li Duoyu grabbed the whole shrimp neatly, then picked up the red-hot hemostat and pinched it at one of the shrimp eyes.

2~3 days after the onset of the disease, at most within a week, the whole pond of shrimp will be directly wiped out, and there is no specific medicine to treat.

Chen Dongqing was a little surprised, he could understand the increase in water temperature, after all, in April and May, the sea water generally warmed up.

At this time, a species of vannamei shrimp called Non-Specified Pathogen Free (SPF) emerged and quickly took over the market.

Li Duoyu smiled: "How is it possible." ”

It's really true, since beating him to make money, that widow Chen still wants to come back to him, and even plans to give him a baby.

Because six or seven are almost a catty, and wild sea-caught prawns, such a big one, are really very rare.

Zhao Erniu said: "Sure enough, I still have a way to make money with Brother Yu." ”

The uncle continued: "By the way, there is a good news that I almost forgot to tell you, the cooperation between the institute and your company is estimated to be able to continue." ”

And they have plans to save the money in the first half of the year, and at the end of this year, they will directly raise kelp with this Li Duoyu, and strive to build him a scale of 50 acres.

The Zhao family brothers, who were originally drying the net today, instantly put their eyes up after listening to Li Duoyu's broadcast.

But almost everyone in the village didn't like him, and only those few village committees were willing to accompany him to say a few words.

As long as this thing is destroyed, the female shrimp will not be suppressed, and will quickly mate and lay eggs under the domination of the reproductive impulse.

made him feel like a clown, although he was the village party secretary, but he, the village party secretary, was like air, without any sense of existence.

But after this set of operations, there is a feeling of flowing water, giving people a sense of disobedience, as if they were often operated before.

Chen Dongqing wanted to scold Gan Niniang, but thinking about Li Duoyu's aunt, she was his sister, wouldn't this become scolding his sister.

Near the wharf, a young comrade was nibbling on dried fish with one hand and drinking beer with the other, and couldn't help but scold:

Li Duoyu smiled and rubbed his fingers: "If you want to learn, you can, pay the tuition first." ”

However, Li Duoyu really didn't say anything wrong this time, and this matter is not entirely related to him, it is one thing for Zhang Xianjin to write a report.

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

And because of the fear of ripping off the skin, it is generally not sold to ordinary tourists, but to fishmongers who specialize in buying it.

In this era, this kind of pliers is not easy to buy, and the supply and marketing cooperatives are definitely not available.

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

Whether it was shrimp fry, clove fish, or the prawns they were catching now, they used to catch them often, and the two brothers often caught extra-large shrimp on the tidal flats.

From clove fish, eel fry, if you add this live shrimp, they have already made a lot of money.

But if it is about the taste, Li Duoyu thinks that Chinese prawns are more delicious than South American white prawns, otherwise there would be no Qingdao prawns for 38 yuan a piece.

Li Duoyu half-squinted his eyes, in fact, cutting the shrimp eyes was not really cut with scissors, but burned off with high temperature.

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

Then it proved to be effective, Chen Dongqing hurriedly said: "Duoyu, you have to keep this technology secret, there are really not many people in China who know this technology." ”

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

Li Duoyu said to the end, and then said: "Everyone, pay attention, the price of live prawns is one Wu Jiao." ”

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

The uncle looked around and said:

"I've also heard people say, it's the Zhang Xianjin who has been at odds with us, he seems to have been unlucky recently, not only criticized by the county's leader, as far as I know, he must write a report on "Why Terminate the Cooperation between the Fisheries Research Institute and Minlong Fishery", and in the past two days, he was also called to the city for a meeting."

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.

In the previous life, when everyone cut shrimp eyes, they used a kind of forceps that were very similar to the hemostats used by doctors for sutures.

Since the eel fry were caught, the two brothers have never made a lot of money, and now the catch is only five or six yuan a day, which is boring to catch.

"Fuck your uncle's Li Duoyu."

And at this time, a voice echoed: "Well said, I finally found a comrade, and I also hate that Li Duoyu very much." ”

The young comrade sitting on the reef was stunned, and looked at the young man in front of him who was similar to himself, and always felt a little familiar, as if he had seen it somewhere. (End of chapter)
