1, pond renovation and disinfection: after the Spring Festival on the pond renovation, dry pond exposure, in mid-April with 35 kilograms of quicklime per acre and water sprinkled throughout the pond (including the pond) disinfection, in early May into the water 15 to 20 cm, per acre with 20 pounds of tea seed cake for pond clearing, clearing miscellaneous, fertilization.

2, fish stocking: in order to extend the optimal growth period of eel, eel fry has been equipped with a boiler, the temperature of 28 ℃ of the greenhouse constant temperature room culture, the beginning of June, the water temperature is constant at 24 ℃ above into the earth pool, stocking specifications for 60 ~ 100 tail / kg, put the fry with potassium permanganate disinfection, and sub-specification of the sub-ponds, stocking amount of about 1800 tails per acre.

3, water quality management: do a good job of water quality control is the key to high yield and efficiency of the eel. First, change the water diligently, plus water change 2 to 3 times a month, each time 15 centimeters, especially in the later stages of breeding need to change the water diligently, and increase the amount of water change. The second is to open the oxygen, the pond is equipped with a water tanker type oxygenator, depending on the weather conditions to adjust the oxygen time, in the late breeding, especially in the high temperature season, the oxygen time is not less than 8 hours a day, to improve the dissolved oxygen to improve the water environment in the pond. Third, the regular use of biological agents, in the late stage of aquaculture due to the pond stock, residual bait, feces, water quality is easy to deteriorate, 1 to 2 times a month with EM bacteria original dew 500 g / mu, in addition to the appropriate use of photosynthesis bacteria and bacillus spores, and so on.

4, feed feeding: according to the eel's different growth period to adjust the formula of the feed, feed protein is not less than 45%, fat content is less than 8%, depending on the water temperature, weather and eating / day day, the amount of feed accounted for the volume of fish 2 ~ 3%. Every 7 to 10 days to adjust the feeding amount, the number of times a day feeding for 2 times, before feeding with a feed mixer and add the right amount of soybean oil, feed are cast on a fixed food table to reduce feed loss, easy to observe the eel eating dynamics.

5, disease control. Breeding period every 15 days sterilization, insecticide, while the regular use of biological agents and water quality improver, in addition to the use of 2 times a month rhubarb, Huanglian, garlic and other herbs crushed and mixed with the feed and feeding, so that can effectively prevent and reduce the incidence of disease, in recent years the farm to take the listed measures after the survival rate of more than 90%.
