Now I'm going to ask Mr. Nghiem about the difference between these two ponds. The round pond is more advantageous when we collect fertilizer or waste water. It will be easier to clean than the round pond. In addition, when we clean the pond, the surface area will be less exposed. So it's easier to clean. The pond will be cleaner and the shrimp will be healthier. In addition, the round pond on the ground is less expensive. Whether it's a motor or electricity, it's the same. In the underground pond, we need to install a motor. This pond needs 4 fans and 4 motors. It will increase the cost of buying electricity. The round pond can only be installed with 2 fans. Because it's very strong. Is the water quality control process different between the two ponds? It's different. The round pond is easier to control. It's much easier to collect water. In the underground pond, the water level is always the same. So the round pond is a bit dirtier than the round pond. It depends on each person's preference. In general, the round pond is more convenient when we collect fertilizer or waste water. In the round pond, we only need one person to do the job. It's less labor-intensive. We only need to turn off the fan and do the job alone. We collect all the waste water and put it in the pond. Then we go out and collect it. In the underground pond, we need to install a motor. We need a person to hold a knife and a person to pull the cement out. So we need at least 2 people. What about the collecting process? The round pond is easier. We can get rid of the waste water quickly. We don't need to turn on the fan. In the round pond, we only need one person to do the job. In the round pond, we need to turn off the fan and turn on the motor. It's more convenient. We need to adjust the fan. It takes more time. What about the 100% collection process? Are there any differences? In the 100% collection process, we only need to turn off the fan. But the round pond is faster? Yes, it's faster. In the round pond, we can collect the shrimp cleaner. The shrimp don't hide in the roots. So the shrimp can be collected cleaner. In the round pond, we can collect the shrimp cleaner. But in the round pond, the shrimp can't hide in the roots. So the shrimp can be collected cleaner. In the round pond, we can collect the shrimp cleaner. Why don't people move from the round pond to the round pond? It depends on the geographical location. Some people still want to build the round pond. But the round pond costs more. They can't build the round pond on the same land. They can't build the foundation on the same land. In the round pond, we have to build the foundation on the high ground. So it's easier to collect the shrimp cleaner. We can also build the foundation under the pond. Instead of building the foundation on the ground, we can build the foundation on the bottom of the pond. But we have to set up the machine. Because the pond is below the water level. So the shrimp can't escape. The round pond is much more convenient. Most of the round ponds have just been developed. How long has the round pond been in Vietnam? About 2-3 years. In the past, people preferred the ground pond. People didn't believe that shrimp could be raised on the ground. If you have a field, you don't have to build the round pond. If you have a machine, you can still collect the shrimp from the ground. You don't have to dig the ground. As long as you have the foundation, you can build the round pond. It's fast and easy to use. If the weather is not rainy, the round pond can be built faster than the ground pond. We have to dry the soil to make the foundation stronger. So we have to cover it with mud. The same goes for the soil. We have to dry it thoroughly. Is the soil in the round pond similar to the soil in the round pond? The soil in the round pond is usually higher than the soil in the round pond. The water is less in the round pond. That's why the shrimp can't eat much. The shrimp is usually in the middle of the round pond. The water is less in the round pond. That's why it's easy to have a storm. If the water is less in the round pond, the shrimp cannot eat much. We have to do a lot of things to make sure the water is clean and fresh. We only need to water once or twice a day to make sure the water is clean and fresh. How much land do you have? We have about 1,000 to 1,200 acres. We can grow 1,500 to 1,600 acres. But it's not easy to control. We can grow 1,000 to 1,200 acres. We can grow them slowly. It's easier to control when we divide the land into smaller areas. For example, instead of growing 2,000 acres, we can grow 2,800 acres. We can't grow 2,000 acres, but we can grow 2,800 acres. If there's an accident, we can grow 1,000 acres. If there's an accident, we can't grow 1,000 acres. The smaller the area, the faster and more effective we can do it. How do you balance the land you have? We need a system to grow shrimps. Sometimes we need 3 water tanks to grow shrimps. But we have to pay attention to the system. Because we use water to grow shrimps. The better the system is, the easier it is to grow shrimps. Can you tell me how to calculate the right amount of BAC and purple medicine? The farm uses 15mg of BAC, and 3mg of purple medicine. It depends on the water level. In the western region,erapistic areas, they have a lot of water almost 30 BAC. We can grow around 10 BAC of purple medicine. But we just need about 15-20 BAC of potions. And about 30 BAC of rice paddy. We mainly take care of fresh water. We don't have any fertilizer and we don't have any weeds. It's not 99% clean. 100% must be clean. We have to use a lot of water. We have to change the water very little. We have to deal with it in 3 days or 2 days. When we can use it, we have to use it all. We have another bucket. We have to use it in 5 days. In 5 days, the weeds will come back. It's very clean. If the environment is nice, it's easy to grow. If it's sunny and warm, it's easy to grow. If it's not sunny, it's hard to grow. If it's sunny, we can get a lot of food. It's cool. If the ground is dry, it's okay. We can walk on it. If it's sunny and rainy, it's easy to grow. The water in the bucket is clear. Yes, it is. But when we walk around the processing area, it's very muddy. There is a lot of toxic water in that bucket. We have to clean it up. The water is clear, but it's still muddy. The water in the bucket is still muddy. We can use clean water to clean it up. We can't use dirty water to clean it up. We have to use a lot of filters. We can't clean it up. We have to use the water we use to clean the bucket for 24 hours. We shouldn't leave it for too long, right? Yes, we shouldn't leave it for too long. How long should we leave it for? We can use it for 3 to 5 days. If we leave it for too long, it will grow back. It will grow back, right? Yes, it will grow back. If we use it quickly, the water will be cleaner and safer. If we leave it for too long, it will grow back. If it grows back, we won't see it.
