Hello everyone, today we come to visit a 7-hectare shrimp farm. This shrimp is raised clean, that is, no antibiotics, no drugs. We will explore why people can do that. Let's start visiting. We are standing at the source of the river. The water comes from the channel, the salty sea water. This is the tank. The water comes from the channel, the salty sea water. Let's go over there and see. This is the system that pumps water into the treatment tank. This is the reservoir. In the early days, people dug this reservoir to prevent the garbage from entering the pump. The pump then pumps the water into this tank. The pump then pumps the water into this reservoir. The water then flows into this reservoir. This system is 250 meters long. You can see that this tank is being washed. It's been raining a lot lately, so it's a bit dirty. This tank is being washed. This is the treatment of BAC and anti-inflammatory drugs. The pump has stopped, so I can't show you. There are two types of chemicals that are used in this treatment. BAC and anti-inflammatory drugs. The color of BAC is still yellow in this tank. Normally, the water level reaches that yellow line. The water does not flow through this tank. If the pump is too strong, the water will overflow. The water leaves holes at the bottom of the tank. There are many chemicals here. Here are the chemicals. There are many chemicals here. If the pump is too strong, the water will overflow. The water will overflow. Now let's go around this 250m long water treatment system. This is the water treatment system. This is the first stage. The length of this net is about 20m. The depth is about 2m from the top to the bottom. The design is from this side to the other side. This is to prevent the water from splashing. This is the back side. The water flows from the left to the right. The length is about 20m. 20m is the length of a net. The weather today is stormy, so the air is cool. It's not sunny and it's not raining. It's very convenient for us to go around like this. This is the area where people are cleaning up. It's raining, so the area is empty. There are 5-6 layers of nets, but there is still a lot of mud here. This is one of the wells to collect the water. The water is being collected here. This is almost the end of the water treatment system. There is still a lot of mud here. It sticks to the bottom, the net, and the shore. This is where the water is being collected. The water is being collected here. This is the end of the treatment system. From that end to this end is 250m. At the end of this stage, we start to treat chlorine. This is the decision step of the treatment system. Let's go to the chlorine treatment box. This is the chlorine treatment box. We haven't used the fuel pump yet. We only use the pump to release the chlorine. The chlorine is mixed at a rate of 20 or 15 BPM. Or 10 BPM. The experience of mixing chlorine is that we pour the water in first. Then we put the chlorine in later. Don't pour it all at once. If you pour it all at once, the chlorine will explode. It's scary. The principle of chlorine is that the chlorine goes after the water. The chlorine goes after the water. The chlorine flows at a fixed rate. The water flows in according to the flow rate. The chlorine is processed here. The chlorine goes into this tube. The chlorine is transferred to the other tanks. After the water goes through the 250-meter treatment tube, the water goes into the ready ponds. This is pond 3. Over there is ready pond 1. The water stays in here for 24 hours. The water stays in here for 48 hours. The amount of chlorine in the water is almost zero. The water is ready to be used. We have 4 ready ponds here. This is Mr. Vuong, the farm manager here. He is in charge of the infrastructure. He is in charge of the design of water pipes and oxygen. Mr. Vuong, how many ready ponds are there in total? There are 4-5 ready ponds. This one has more than 3,000 ready ponds. Over there is 8,000 ready ponds. This one is smaller. It has 6,000 ready ponds. 6,000 ready ponds? 6,000 square meters. The reason why the water level is so low is that the water level in these 15 ponds is about 70%. The water level in these 15 ponds is about 70%. When the water level reaches this level, how can you make sure that the chlorine is gone? It depends on the amount of BVM. The amount of BVM we use per day. We calculate the amount of BVM when the water level reaches this level. How long does it take to reach this level? It takes about 20 hours to reach this level. So you start from the outside, from the processing of BVM and BVM? BVM is processed from here to here. It takes about 48 hours to reach this level. It takes about 24 hours to reach this level. BVM and BVM are processed in order to get the right amount of BVM. When the water level reaches this level, the chlorine is processed. When the water level reaches this level, the chlorine is processed. It takes about 24 hours to reach this level. If we don't use a lot of BVM, the water level will be low. We use a 240-meter pump and we use more than 5,000 tons of BVM. We use more than 5,000 tons of BVM. The water level is just right. It will be more effective. The water level will be more effective. Some people can use a pump directly to the sun and then use the chlorine to fill the tank. That's one way. It will help the sea level. If people live in the lowlands, or in the highlands, we can build it from the beginning in order to get the right amount of BVM. We pump the water from the river and use a big bucket to fill the tank. When it's clear, we use the chlorine. Because the water level is high, it's hard to control the amount of BVM. How much BVM do you use? It depends. We use a pump. We know the water level. Then we calculate the time to pump the chlorine. When we pump the chlorine, we follow the flow of the chlorine. It will be more stable. How much BVM do you pump to get the right amount of BVM? It depends on the weather, the water level, and whether it's clear or muddy. How long does it take to pump? It depends on the flow of the chlorine. We calculate the time to pump the chlorine. The same goes for BVM? Yes, we follow the flow of the chlorine. The other guy pumps it 5 times. How much BVM do you use? We use 3 kg of chlorine and 15 kg of BVM. It takes 4 hours. If we pump 250 kg of chlorine, it will be 1,000 BVM. It depends on the weather. 3 kg of chlorine for 1,000 BVM. 3 kg of chlorine for 15 kg. 13 kg of chlorine for 1,000 BVM, 15 kg of BVM for 250 kg. If you clean the pond, what happens to the water? After cleaning, we pump it for 24 hours. We save the water for 2 days. We collect the water first. We use the pump to process it. When we pump it, we filter it. After filtering, we collect the water. We use the pump to process it. How do you clean the pond? Depending on the amount of water we use, we have a plan to clean it. It usually takes 10 to 15 days depending on the water level. If we use less water, the pond will be damaged. If we use more water, it will take another 10 to 15 days. If the shrimp grows from 200 km to 100 km, we need to adjust the water level. If the shrimp grows too much and the water level is low, the shrimp can get sick. We need to control it. You have to find a way to keep it clean first. So that the people can breathe. To breathe? Yes, the shrimp. And so they can eat. If it's clean, the shrimp won't eat as much. But important is that you need to clean it well. To separate all the food. So that it's clean. If it's clean, the water won't be dirty. Because the shrimp The water is cleaner. Sometimes, when we don't have enough food, the shrimp will get stuck in the mud and get dirty. When the shrimp grows stronger, it will be more fertile. When it's fertile, it will be weak. When the shrimp eats, it will get sick. So we have to control it. It's not good for the shrimp, right? The old people said that the disease comes from the mouth. The disease comes from the mouth. The shrimp lives by eating and drinking. We have to control it. If the environment is clean, the shrimp will be healthy. This farm is more than 7 hectares. The investor here is still maintaining two models. One is the bottom layer. There are about 5 to 6 bottom layers here. There are still cotton, bottom layer, and fan. On my left is the new model. On top of it, there is a net and a net. You can see the net here. The net is big to protect the net. The net is big to reduce direct sunlight. The system is about 15 acres. People here do it very quickly. In May, they started the construction of this 7-hectare project. Today is November. In 6 months, they designed the system. The system consists of a pipe system, a water supply system, a round-tube system, an oxygen supply system, a net system, and a water treatment system. The construction started in May. Today, it has been more than 5 months. The shrimp is about to be harvested. The shrimp is in size 25 and 30. I will show you the details later. Let's go into the bottom layer. This is the bottom layer. This is the oxygen system. There are 4 fans. I will show you the bottom layer later. Let's take a look at the shrimp. This is the bottom layer. It is in Japanese. The dirt will be collected here. I will remove it by hand. These are dead corners. The oxygen cannot reach here. The water will be collected here. The shrimp is in size 25. Last week, the shrimp was harvested. This is a bag of food. The bag is full. The stairs are made of stone. These are the water drainage pipes. The shrimp is packed in a bag like this. It will be dried and burned. In addition to burning and throwing away the shrimp, it can also be used as a chitosan in agriculture. This is the oxygen pipe. This is a pipe with a capacity of about 200. This is a feature of the oxygen blower. This pipe mainly uses stone and concrete. This is the oxygen pipe. This is a pipe to pump biological waste into the sewer. This is one of the ventilation systems. There are 5 machines here. There are several machines like this. It's a bit noisy, so I have to speak loudly. Let me show you. This is the size of the shrimp. This size is about 30. The shrimp is very strong. The shell is beautiful. The shell is shiny and clean. The shrimp is full of vegetables. The vegetables are fresh and beautiful. This is the second pipe. This pipe has a small area of about 200 square meters. It is about 1.4 meters high. I will compare the height of the pipe and the height of the pipe. It is 4 times higher than the pipe. It looks very cool. Normally, I only use one ventilation system. The other one is for storage. Compare with this pipe. It looks very different. The oxygen system here is also distributed in numbers. The distribution is the same as the sewage pipe. It is about 248 cubic meters. This is a ventilation station. There are 5 engines running. In this 15-kilogram system, the farmers designed 2 ventilation systems like this. Each system has 5 engines. This is a water meter. According to the date, the water level of the sewage system is about 8.1 to 8.7. The water level is about 7.9 to 8.1. The water level is about 107 to 106. The water level is about 106 to 107. The water level is about 107 to 106. But I can't find any sign of these. I'm observing the weather forecast. 5 degrees Celsius. 5, 5, 5. No, I can't see anything.
