Giant freshwater prawn, also known as the giant river prawn, white-legged prawn, or golden prawn, is native to Thailand, Myanmar, and Ecuador. It is the world's largest freshwater shrimp and is known as the "King of Freshwater Shrimp".

Giant freshwater prawns have thin shells and thick, tender meat that is rich in nutrients. In addition to these advantages, the cephalothorax of mature giant freshwater prawns is filled with gonads, which have a unique and delicious flavor similar to crab roe.

"The giant freshwater prawn is not only delicious, but also grows quickly, has a wide diet, and is large in size, making it a high-quality economic shrimp species."

Guo Daming spoke eloquently, his notebook filled with dense writing. Li Xiangdong tilted his head to take a look and saw that there was even pinyin on it.

"However, the native habitat of giant freshwater prawns is very warm, and the optimal temperature for their cultivation is between 24 and 30 degrees Celsius. Although our Huichuan doesn't experience freezing temperatures in winter, the lowest temperature is still around zero degrees Celsius. This is a challenge for their cultivation."

Looking at the juvenile giant prawns swimming happily in the bucket, Liu Yuliang said with a sigh, "Then we can't raise them in winter!"

The others also looked at Guo Daming. He had just said that it takes about four months for giant freshwater prawns to grow from larvae to marketable size. If you do the math, they can only be raised once a year.

Even if the price of giant freshwater prawns is higher, if you raise fish, you can harvest several ponds a year, so it may not be less profitable than raising giant freshwater prawns.

Guo Daming tapped his notebook. "I consulted Professor Liu Minle about this. He said that covering the shrimp ponds with plastic film can keep them warm. When it's coldest, you can light a fire to raise the temperature."

"We've built greenhouses before, but shrimp ponds are this big, how do we build greenhouses?"

The shed for cultivating tatsoi seedlings was built under the guidance of Li Jinshan and Guo Haiguang. The north side was made of rammed earth, supported by bamboo poles, and covered with agricultural film.

Li Xiangdong thought for a moment and realized that the advanced greenhouses in his previous life used steel structures and polyethylene films.

"Just weld the frame with steel pipes and then cover it with a special film."

Li Xiangdong took the notebook from Guo Daming and drew a rough outline on the paper. "To control the temperature, just put in a few artillery shell furnaces."

Everyone nodded, but the heavy responsibility of buying steel pipes and film still fell on Li Xiangdong.

Nowadays, purchasing agricultural inputs such as fertilizers and seeds requires a letter of introduction and a permit.

Without further ado, 100,000 shrimp larvae are ready to be released into the pit!

Li Xiangdong rode his bike straight to Liu Donglai's house, just in time to wish Uncle Liu a Happy New Year!

It was only after the Yanling earthquake that Liu Donglai truly became close to Li Xiangdong, treating him like a family member.

Li Xiangdong naturally wouldn't let this opportunity slip by, and his treatment of Liu Donglai was now imbued with the usual respect mixed with a sense of kinship.

This visit was both to pay New Year's greetings and to ask for help. Li Xiangdong brought a few sausages, half a basket of local eggs, and a large watermelon left over from before the New Year. The gifts were slightly more extravagant than those for visiting relatives, but not excessive.

For some reason, Liu Donglai has always lived alone in Huichuan County, and his family members have never shown up.

Li Xiangdong didn't go to Liu's house either, but went straight to the county committee compound.

Upon entering, I saw Liu Donglai indeed reading documents in his office!

"Uncle Liu, Happy New Year!"

Li Xiangdong stood at the door with a big smile and greeted everyone loudly.

Liu Donglai looked up and saw it was Li Xiangdong. A genuine smile appeared on his face. "Come in, come in! You've got a conscience, you still know to wish me a Happy New Year!"

Li Xiangdong put the basket by the door and said reproachfully, "Look at what you're saying, I came here on the 29th!"

"That happened last year, haha!"

"I brought you a watermelon. Eat some to cool down. Look, your lips are all cracked."

"Okay, okay, okay!"

Liu Donglai smiled and agreed. He was currently busy dealing with the mess left by Deputy Director Zhang. Before the Lunar New Year, taking advantage of Li Xiangdong's unjust arrest, he began investigating Wei Baoping's embezzlement, bribery, and abuse of power.

With so many things to deal with, it was impossible for him not to get angry.

Fortunately, Li Xiangdong was there. With him paving the way, the economic improvement of Huichuan County became much easier.

If the planting of "Pohong No. 1" high-yield corn, "Qiongsu" watermelon, and Wutapai is promoted throughout the county this year, it should not be difficult for farmers' income to double.

"Uncle Liu, our brigade is facing a problem and urgently needs your help!"

Seeing Li Xiangdong's serious attitude, Liu Donglai said solemnly, "Tell me, what is it?"

"Our team is planning to raise giant freshwater prawns, but they need a constant temperature to grow. We've been discussing building a cover for the prawn pits!"

"Macrobrachium rosenbergii?"

When he was in Yanjing, he ate quite a lot of seafood, so why had he never heard of giant freshwater prawns?

Li Xiangdong explained, "Yes, this is a type of shrimp from abroad. The Pengcheng Fisheries Research Institute has just bred shrimp seedlings that are adapted to aquaculture in our country!"

Liu Donglai raised an eyebrow. "The recommendation letter you asked me to write last time, was it for the giant freshwater prawns?"

He thought Li Xiangdong just wanted to buy some high-yield fish fry!

“Shrimp are more expensive than fish!” Li Xiangdong gestured with his hands. “If these shrimp grow big, they can weigh up to a pound! Have you ever seen shrimp this big?”

Wow! How much would that cost?!

Liu Donglai became very interested. Li Xiangdong was always exploring new ways to make money, and the key was that he wasn't doing things blindly; he made a lot of money from each one!

"Tell me, what do you need me to do?"

Li Xiangdong didn't mince words, "I need the steel pipes and plastic film to support the greenhouse now."

"I'll give you a slip now. Go to the agricultural supply store at the supply and marketing cooperative and buy plastic film. If they don't have it, have Director Yu get it for you right away!"

Liu Donglai walked to the table, picked up a pen, and quickly wrote a note. "As for the steel pipes, I'll write you a letter of introduction to take a look at the steel mill in Dongfang City!"

President Yu was already acquainted with Li Xiangdong, not to mention that Secretary Liu personally wrote the note.

As soon as Li Xiangdong arrived, President Yu instructed the sales clerk on duty to go to the warehouse to check the inventory.

"I remember we received a batch of agricultural film before! Xiao Zhang, go find it!"

"Xiangdong, you don't need to go all the way to Dongfang City to get steel pipes. I remember that our supply and marketing cooperative's scrap metal company has a batch of steel pipes. You can take them there, weld them together, and they'll be ready to use!"

What a great thing!

Li Xiangdong happily thanked the company president and followed Xiao Zhang to find agricultural film.

The two searched the warehouse thoroughly, finally finding ten rolls of light blue agricultural film, eight meters wide and two millimeters thick.

Will this work?

"Yes, that's it!"

Li Xiangdong handed Xiao Zhang a box of "Yunyan" cigarettes, saying, "Thank you for your hard work, Brother Zhang! I'll call someone to come and move it in a bit, you can rest for a while."

Xiao Zhang smiled as he took the cigarette and put it in his pocket.

Although it's tiring, working for Li Xiangdong is never a waste of time!

This child is sweet-talking and polite. Therefore, as soon as they heard Li Xiangdong was coming, everyone wanted to interact with him. (Adult giant freshwater prawns, giant freshwater prawn roe, giant freshwater prawn roe)
