Water quality management. When the moray eels are first put into the pond, due to the difference between the pond environment and the marine environment, the moray eels are very active, producing "nausea" and mucus secretion. To maintain the quality of fresh water after 1-2 days in the pond, the water needs to be changed 100% every day. In the hot season, the water needs to be changed twice a day, and the daily water change volume should reach 80%. Normally, the daily water change volume is controlled at about 50%, and the water temperature drops in winter. The transparency of the pool water should be maintained at 30-50 cm, and the pool water should be kept above 1.2m in winter.

Prevention and control of fish diseases. Enteritis is the most common disease in sea eel farming. The main reasons are poor water quality in hot seasons, feeding spoiled bait, and fish overeating. Treatment should first improve water quality, not feed spoiled bait, control fish food intake, and then add 3‰ furazolidone to the bait for 3-5 consecutive days. Feeding can be done regularly from August to October to prevent fish diseases.

Other management. Regularly inspect and observe the ponds, 1-2 times a day. Check the dams, nets, and gates for gaps or holes. If there are any, repair them in time to prevent the eels from escaping. In addition, check for sick or dead fish. If found, remove them in time to prevent the spread of diseases. Pay attention to the feeding and swimming of eels, and take timely measures if any abnormalities are found.

Feeding amount for farmed conger eels. Feeding amount varies greatly with temperature, water quality, weather and eel species and specifications. Generally, under good temperature, water quality and weather conditions, the daily feeding rate of 1 gram of eel is 8%~10%, 3 grams~5 grams is 6%~8%, 5 grams~10 grams is 5%~6%, and 10 grams~20 grams is 4%~5%. When conger eels grow to more than 20 grams, they can be farmed according to the methods and feeding ratios of adult conger eels. As for the determination of the specific feeding amount, it depends on the feeding situation of the eels. Generally, it is necessary to master the training bait given each time, and it is advisable to eat it within 1 hour to 1.5 hours.

Feeding frequency of farmed conger eels. Newly farmed eels in the secondary pond can be fed three times a day. When the conger eels grow to 0.5g or more, they can be fed twice a day, from 7 am to 8 pm and from 1 pm to 2 pm. In summer, when the water temperature rises above 33℃, the feeding ability of conger eels is poor. The feeding time should be advanced to 5: 00 ~ 6: 00 and 10: 00 ~ 11: 00 in the morning. No feeding in the afternoon or once in the morning, and the afternoon feeding is postponed to after 6: 00 pm. This time will vary with the specific climate and water conditions.

The above is all about the increasing number of conger eel farmers and what kind of technology is needed for conger eel farming. I hope it will be helpful to you!

You must pay attention to the breeding density, choose varieties with a relatively high survival rate, and then replace water resources in time during the breeding process. You should choose high-quality feed for feeding, and you should be equipped with an aerator. Pay attention to the breeding site, which should be around 15 or 25. The water level must be controlled above 1.2 meters, and the surrounding buildings must be solid.

Be sure to choose a suitable breeding farm, and then you should also choose the right bait, you need to change the water source in time, and you need to keep sufficient oxygen in the water. Finally, you need to promptly remove some weeds from the water celery shed.

Conger eel is a very common and relatively large aquaculture, with great economic benefits, but certain scientific and technological skills need to be mastered in the breeding process.

2. Is it tiring to raise eels?

Eels are very easy to feed and not tiring.

Breeding temperature conditions: Eels are suitable for living in water temperatures of about 12 degrees Celsius. Therefore, when breeding eels artificially, the water temperature should be kept at about 12 degrees Celsius to allow the eels to grow faster. Breeding location: Eels live in saltwater areas, so eels can be raised in ponds. The water in the pond should not be too deep, about 1 decimeter, and the walls of the pond can be paved with bricks.

Disinfection: After the pond is built, it needs to be sterilized and disinfected, and then it can be placed in the sun before the eel fry can be placed in the pond. Feed: Eels can eat bloodworms, live water fleas, earthworms, etc. You can put some water plants in the pond for the eels to live. Generally, they can be fed twice a day.

3. I want to learn about conger eel farming. What are the online learning methods?

Eel is the general name of eels, belonging to the order Microhyliformes. It is a kind of fish in the ocean. It looks like a long snake, tastes delicious and is rich in nutrition. With the hot development of China's aquaculture industry, high-end aquatic products such as eels have become more and more common in the market in recent years, and their prices are also very expensive, but they still cannot stop people's buying craze. Because of such market prospects, my country has initially formed an eel industry sales chain integrating eel breeding, breeding, and adult eel breeding. But in fact, there are still many loopholes in my country's artificial breeding technology, which greatly increases the difficulty of eel breeding. If you don't pay attention to mastering the correct breeding methods and techniques, you may fail. So, how can you raise yellow eels well? Eel breeding eel breeding methods and precautions, seed selection. Because the price of yellow eels is very high, you should choose plump, healthy, and active larvae for breeding. Otherwise, it is easy to die, and there will be direct cost losses.

Generally speaking, this breeding method is chosen to ensure the survival rate of eels, making them easier to survive in the subsequent breeding and management process. Water quality management. As a marine organism, eels must be far away from the bad water quality environment, so it is recommended to breed them near the seaport. In order to maximize the restoration of the marine environment of eels, a special breeding farm should be established in the breeding area. The water temperature is required to be maintained between 8℃ and 30℃. At the same time, it is important to pay attention to the water flow rate not being too fast, which will easily cause the fish to disperse. In addition, oxygen tubes can be placed in the breeding site to ensure that there is enough oxygen in the water to support its activities. Eel breeding technology. Breeding density. The breeding density needs to be adjusted according to the type of eel. Generally speaking, if the eel is small, about 120 eels can be placed in one square meter. During the breeding process, special attention should be paid to the growth of eels, and weak eels can be carefully cared for separately to avoid the law of the jungle.

Disinfection. Disinfection is an important task in eel farming, which can be roughly divided into three stages: first, disinfection is required before the fry are released to remove various bacteria carried by the fry; second, disinfection of the seawater in the breeding area before harvesting is mainly to remove impurities and bacteria remaining during the breeding process. Finally, disinfection is carried out after harvesting to facilitate the next fish farming and avoid pollution of seawater. 5. Feed. Eels are carnivorous fish that mainly prey on small fish, shrimps, crabs, earthworms and other animal foods. After sexual maturity, the digestive organs of adult eels will gradually shrink and stop eating. Don't worry about this.

The above are some techniques and precautions for eel farming. In fact, eels have relatively poor adaptability to the environment, so whether the growth environment is suitable is the key to determining eel production. Only by paying special attention to the above points can eels grow well.
