The culture mode of eel

With the progress of culture technology, the culture of eel has been greatly improved, thus increasing the output of eel in our market. But how much do you know about the model of eel farming? Is the eel farming still the same as before? Well, today we are mainly here to learn about several common culture models of eel farming at present. Let's take a look.

1. Open-air aquaculture

Open-air aquaculture is the most important way for raising eel in China. It is an aquaculture pond built in the open air, and then it uses nearby rivers, rivers and other water resources for breeding. The most troublesome way is the management of water quality, we need to change water every day, and we also need to artificially replenish the oxygen content in the water to improve the water quality to achieve the conditions for raising eels. In the time of breeding, we also need to divide the eel ponds into first-class, second-class, third-level and seedling ponds, so as to facilitate management. The reason why open-air aquaculture is widely used is that its breeding cost is low, which is very important for farmers, but the yield of farming in this way will not be very high, because the management is more complex, so it is necessary to reasonably control the quantity of farming.

2. Soil pond culture

Soil pond culture is actually similar to what we call pond culture, but the focus of soil pond culture is that its bottom is soil and does not need to be repaired by cement. Secondly, when we choose soil ponds, it is best to choose sunny places with adequate water sources, do a good job of drainage and diversion system, and at the same time, we also need to do a good job of anti-escape measures and fence around. There is the silt in the pond should not be too deep, generally about 20 centimeters is appropriate. Finally, it is necessary to sterilize the fish ponds before stocking, pour fertilizer into the fish ponds after disinfection, and cultivate the water body before breeding. This is one of the most traditional farming models, and I believe most people know it better.

3. Warm running water culture

Warm running water aquaculture is a relatively advanced way of breeding at present, which adopts the mobile way of warm water. In aquaculture, we should control the water temperature, generally at about 27 degrees, and keep running water to form a self-flowing way of imitating living water. In this way, it has the characteristics of fast growth, few diseases and insect pests and high yield, but it costs a lot in construction and requires high professionalism in breeding technology. In addition to water supply and water control, warm water aquaculture and open-air aquaculture are basically similar.

4. Greenhouse waterproof type

Greenhouse water-stop culture is a culture mode opposite to open-air water culture, but it can also be said that it is a matching culture mode with open-air culture. Water-stop culture in greenhouse and open-air culture are basically the same in terms of culture methods and construction, mainly because of the difference in temperature. the water temperature in the greenhouse should be controlled at about 25 degrees Celsius. In this way, the survival rate is much higher than that of open-air culture, and the culture cycle is much shorter.

How many of the above farming models do you know? What is the most common breeding mode in peacetime? Is there a breeding model that everyone is interested in? In fact, the editor's favorite is warm water aquaculture, but the cost is larger, so the risk is also greater, but the profit is also very attractive.
