Artificial breeding of conger eels is very common. What is the approximate output of artificial breeding of conger eels?

The base has put into production 20 mu, 38 breeding ponds, and the second and third phases of the base are in progress. How to ensure water quality, water temperature and dissolved oxygen in high-density eel farming? Zhang Xu, a breeder at the base, introduced that in order to meet the water quality requirements of eel farming, the breeding water is taken from the seepage water of the Yangtze River (a total of 172 indicators are tested), and a 6,000 cubic meter reservoir is set up in the upper left corner of the base to ensure emergency water supply for 12 hours.

The company has built feed and drug testing rooms, breeding facilities, personnel disinfection rooms and bloodworm breeding pools to ensure breeding safety. In order to prevent sudden power outages, the breeding base is equipped with a special power distribution room and a high-power generator to ensure 24-hour emergency power supply for the breeding base. Science and technology are developing rapidly, and technological progress continues to promote industrial upgrading. In response to the country's requirements for river water management and ecological environmental protection, Huize Fisheries took the lead in opening a new chapter in recirculating water ecological eel farming. The world's largest inland recirculating water eel ecological breeding base will be built in Nanping, Fujian.

Zhaili Town is a provincial town with beautiful environment. The air quality meets the national secondary standard and the drinking water quality meets the national secondary standard. It is an important ecological barrier at the source of the Minjiang River. For recirculating aquaculture, high-quality water source is the key to success. The superior natural environment of Baishi Village has laid a good foundation for eel farming. Located in Wuyishan Nature Reserve, the eels raised here are eels that grow up drinking mineral water!

The total investment of Fujian Huize Fishery Eel Breeding Base is 1.9989 billion yuan. The total area of ​​the project is 800 mu and it will be completed in two phases. After the first phase is put into production, it will produce 6,000 tons of eels per year, and after the second phase is put into production, it will produce 9,000 tons of eels per year. The total construction period is expected to be two years. The first phase is expected to be put into use by the end of 2019, and the second phase is expected to be put into use in 2020. The project covers the entire industrial chain of eel breeding, eel deep processing, feed production, logistics and R&D center.

I think that artificial breeding of conger eels is very common now. The output of artificial breeding of conger eels is about several tons. The profit of this industry is very considerable. Many people choose to do this.

Generally, one acre can produce about 15,000 kilograms. If the scientific breeding conditions are better, it may reach about 20,000 kilograms. The future prospects are still very good.

The output is still relatively high, and the general output is about two tons. And the cost is also quite high, about 20,000 yuan, the income is also relatively high, and the profit can reach more than 30,000 yuan.

Around four to five thousand. Because the technology of artificial breeding is relatively scarce and there may be risks in breeding, the approximate output is not very high.

2. When farmers decide to raise eels, what should they pay attention to when choosing an eel site?

1. Fish ponds for eel farming can be divided into soft ponds and hard ponds

Hard ponds are fish ponds built with cement, stone or reinforced concrete. Advantages: It is more convenient to operate and can prevent eels from escaping. Soft ponds are called soft ponds. Advantages: It is similar to the original living environment of eels. Eels raised in earthen ponds are yellowish blue and more attractive.

Shape: In the early days, the Japanese design was mainly octagonal, in order to avoid dead corners for air circulation. Later, most eel ponds had sufficient oxygenation design, and the shape was designed according to the geographical conditions of the farmers. The eel ponds in my hometown are mostly rectangular.

2. Size

Most of them are from several dozen pings to five or six hundred pings in size.

3. Depth

Four feet deep, about 100-120 centimeters deep.

4. Quantity

More than five eel ponds. The structure, size, and depth of the eel ponds depend on the scale of eel farming. What is the scale? To achieve the greatest farming benefits? In the early days when the price of eels was high, there were many corporate eel farms. However, after the price of adult eels dropped sharply, these corporate eel farms closed down one after another. Instead, family-style eel farms can operate permanently. Mr. Huang Jinyue, who has 20 years of experience in eel farming, mentioned the latest specifications for eel farming, that is, to maintain the scale that is most suitable for oneself and can be afforded by oneself, and the smoother the operation will be.

5. When choosing an eel site, usually consider

The water quality is good, without any toxic components, and the pool is not built in any place with toxins. The land is of good quality and has considerable water retention capacity. It is best to choose a place with sandpaper soil, and try to avoid acidic soil. There is abundant water source, no flooding in the flood season, no drought in the water shortage period, and no water quality disputes. The feed supply is sufficient, the price is low, and there is a place to store it. Convenient transportation, where vehicles can pass; convenient communication, and electricity can reach here. The terrain is suitable for injection and drainage. Easy to manage, good public sentiment, avoid excessive places.

Particularly strengthened measures were taken to prevent eels from escaping.

Be sure to pay attention to the cleanliness of the site. Sanitary problems require hardening the ground as early as possible to avoid problems. Be sure to pay attention to disinfection in the combustion shed.

You need to pay attention to the size, the depth, the structure of the construction, and the specific conditions of the hard pool.

It is necessary to choose excellent varieties for breeding, pay attention to water quality, and try to remove impurities in the water regularly.

3. Do you know what the eel breeding and management technology is?

Eel is a general term for species under the classification of Anguilla. It is a marine fish. It looks like a long snake, tastes delicious and is rich in nutrition. It has always been called the ginseng in the water. With the hot development of my country's aquaculture industry, high-end aquatic products such as eels have become more and more common in the market in recent years, and the price is also very expensive, but it still can't stop people's buying tide. Based on this market prospect, my country has initially formed an eel industry sales chain integrating eel breeding and adult eel breeding.

Since eels are expensive, it is necessary to select plump, strong and active seedlings for breeding, otherwise it is easy to cause death and direct cost losses. Generally speaking, this kind of seedlings is selected to ensure the survival ability of eels, and it is easier to survive in the later breeding management process. Water quality management. As a marine organism, eels are of course inseparable from a high-quality water quality environment. It is recommended to breed near Haikou. In order to restore the marine environment to the maximum extent, a special breeding site should be built in the breeding site. The water temperature should be maintained between 8℃ and 30℃. At the same time, it should be noted that the water flow speed should not be too fast, which is easy to defeat and disperse the fish. In addition, oxygen pipes can be placed in the breeding ground to ensure that there is enough oxygen in the water to support their activities.

Breeding density. The breeding density needs to be adjusted according to the species of eels. Generally speaking, if it is a small eel, about 120 eels can be placed in one square meter. During the breeding process, we also need to pay special attention to the growth of eels. Those who grow slowly can be taken care of separately to avoid the law of the jungle.

Disinfection. Disinfection of eel farming is an important task in eel farming, which can be roughly divided into three stages. First, before storage, the fry need to be disinfected to remove various bacteria carried by the fry; second, the seawater in the breeding area is disinfected before harvesting, mainly to remove bacteria bred by impurities left over during the breeding process; finally, disinfection is performed after harvesting to facilitate the next fish farming and avoid polluting the seawater. Feeding. Eel is a carnivorous fish. It mainly catches small fish, shrimp, crabs, earthworms and other animal foods. After adult eels reach sexual maturity, their digestive organs will gradually atrophy and stop feeding. Don't worry. After spawning, they will eat independently.

First of all, you should choose the right temperature and environment, and change the water in time during the normal breeding process to keep the water clean. You should also pay attention to sufficient oxygen in the water, choose some high-quality feed, and do a good job of disinfection and cleaning.

First of all, eels live in saltwater areas, so eels can be raised in ponds, but the water in the pond must not be too deep, about one decimeter is enough. After the pond is built, it is necessary to kill bacteria and disinfect it, and then expose it to the sun before the eel seedlings can be placed in the pond. In addition, sufficient feed should be prepared for the eels, such as red worms, live water fleas, earthworms, etc., and they should be fed twice a day, so that the eels can grow healthier and more nutritious.

The most important thing in raising eels is to control the number of eels and the water temperature. Eels have very high requirements for water temperature, and it must be a temperature suitable for them to reproduce.

The first sign is that you need to choose a place with better water quality, and the ventilation must be very good. The area should not be too large, and the height should be about one meter. Then you need to set up some fences or guardrails, and filter them. At the same time, you also need to choose high-quality eel seeds, and choose a mixed feeding method, choose high-quality feed, and then you need to strengthen daily management.
