KỸ THUẬT NUÔI CÁ CHẠCH GAI, CHẠCH LẤU TRÊN AO NƯỚC SUỐI | PHẦN 3

At the beginning of the winter, I don't release the net anymore. And this is very cheap. The places for fish to live are called bamboo tubes. I use things that are not worth the money to create a place for them to live. Because this fish has to live in a stone pit. And to find out more about how to raise catfish and the biological characteristics of this fish, we will meet Mr. Viet, one of the first people in the North to bring catfish to the North. Hello, Mr. Viet. Hello, everyone. Can you tell me the characteristics of this catfish? What are its biological characteristics? How can we apply it to the environment we are raising it in? This is one of the best environments to raise catfish. The water is flowing smoothly. The oxygen is very large and the water is very clean. In the highlands of the North, it is very convenient to raise this fish. There are characteristics that are not found in other areas. The water is very clear. It has a high slope, so it flows and creates a lot of oxygen. People use it a lot. These characteristics are used to raise high-value fish that are beneficial to people. This catfish may be five to seven times more beneficial than other catfish. If people can use this source of water, they will be able to make a lot of money. Yes. I see that in most northern provinces, the natural conditions, especially the source of water that flows from the springs like this, are very high. It brings a very good water quality and oxygen system. It is suitable for many fish. A lot of fish can be raised here. We are choosing a direction. We choose high-value fish. The size of the farm in the mountains is smaller, right? That's right. We should choose models like this. Can you tell me more about this fish? How long can we raise it to harvest? When is the best time to raise it in the northern market? This fish can be raised for more than a year. This fish eats very little, so people don't have to worry about it. If the fish is big, people will harvest it first to sell it. We will get the capital back. If the fish is small, we will raise it for another month or two. When the fish is big, it consumes very little food. When the season comes, we will raise it like other fish. At the beginning of May, spring, summer, and early autumn, we can raise it. At the beginning of winter, we don't release the net anymore. This fish is very cheap. We use bamboo tubes to raise the fish. We use cheap materials to raise the fish. This fish lives in a stone pit. We use bamboo tubes and nets. The conditions of the people in the highlands are very favorable. We can raise this fish. This is the advantage that people don't know about. In Vietnam, people use gold to make money. So people should use this kind of water. In other countries, people don't have this kind of water. So people use high-tech technology to raise fish. In Vietnam, we have a very precious water and ecosystem. We can use it and reduce the production cost of the product. This fish is fed with industrial food, right? This fish is a kind of grass carp. Its nature is to eat meat. It is a kind of grass carp. People can feed it with industrial fish. It has an animal protein content of more than 40%. It can be used as a bait. The consumption of this fish is very low. It will be very low. If we feed it with industrial food, such as grass carp, how much food should we feed it? How much distance should we give it? Its mouth is quite small. So we should use a small fish. It will grow up according to its size. It is very easy. If you are interested, I will share the details for you to do it. How many fish can we feed with this system? If you have this system, you can feed a lot of fish. It depends on the amount of oxygen in the water. For example, this system can feed up to 50-70 kg of fish per meter of water. This is a very good system. It depends on the amount of oxygen in the water. This is a very good system. This system can feed up to 10 fish. We cannot feed up to 10 fish with this system without the water. So the fish in the highland area are also very good because the water is clean and the oxygen is high. This is the advantage of the highlands, where many people have but do not want to explore. I see that the people of the North do not only raise this type of fish, but also many other types of fish. People are very concerned about the problem that in winter, the temperature is low. I wonder if this fish can withstand the temperature in the North? The nature of this fish in the North is called Chach Chau. In the nature of the North, there are many types of fish. In the North, there are many types of fish in the South and Southeast Asia. The answer is very simple. Because the fish still live in the wild, they still survive the normal winter. We raise this type of fish to a certain size so that it has enough energy to resist the winter. In the winter, the fish will not be able to eat, so it needs a certain amount of fat. As you can see, the amount of fat in this fish is quite large. Can you tell me more about the market of this fish in the North? Currently, there are not many people in the North who raise this fish. No one has raised this fish. The demand for this fish is very good. Restaurants and hotels also have high demand for this fish. There are people in Hoa Binh who have already bought this fish. They have already paid the price and can sell this fish. They just have to wait until the day of sale. This fish is being deployed to the mountains. Can we raise this fish in the mountains? This fish is very easy to raise. I have already understood the nature of this fish. Many people raise this fish in the rivers and lakes. The water level in the mountains is low. The water level in the mountains is high. But the water level in the rivers is different from the water level in the mountains. The water level in the lakes and lakes is also different. Each model of raising this fish has its own characteristics. People should research and then deploy it. Thank you Mr. Viet for sharing information about this fish. In the previous video, we talked to Mr. Viet about the model of raising this fish. You can watch the video in the description. Thank you Mr. Viet for talking to us. Goodbye and see you again.
