Monopterus albus culture method A Monopterus albus culture process

1. Choose a pond with good water quality, no pollution source and little external interference. Build a bracket in the pond with bamboo and fix the four corners of the cage on the bracket. There is a dining table in each cage. Monopterus albus has the habit of cannibalism, so the stocking specifications are basically the same, generally 20 to 50 grams per tail.

2. The stocking time of Monopterus albus should be in April, May or August to September to avoid the sexual mature breeding period of Monopterus albus from mid-May to July. The optimum temperature for the growth of Monopterus albus is 24 to 28 degrees Celsius.

3, feeding should be timed, eels lie down during the day, come out at night, and it is appropriate to feed from 6 pm to 8 pm. Feed should be fresh, not rotten. Before feeding, the feed should be washed, soaked in 3 to 5 grams of salt per cubic meter of water for 10-20 minutes, and then washed with clear water before feeding. Freshwater small miscellaneous fish are generally selected, and the daily feeding amount is 3%-5% of the total weight of Monopterus albus in the cage.

4. When artificially feeding, due to feeding a large amount of feed, the excrement discharged by Monopterus albus is easy to pollute the water quality, so it is necessary to replenish fresh water frequently to keep the water quality fresh. Change the water every 7 days in spring 10 day, and every 3 to 5 days in summer.

5. Cages should be disinfected regularly, each cubic meter of water should be bleached with 10g water, and the whole pool should be sprinkled with water. After stocking, a proper amount of loach can be stocked in the cage, which can divert oxygen and eliminate the residual bait of Monopterus albus by using the habit of loach running upstream and downstream. Put a certain amount of silver carp in the pond to adjust the water quality.

6. Clean the cage in time, remove excessive sundries and attached algae, and keep the water exchange inside and outside the cage smooth. It is best to plant aquatic plants in cages, especially water hyacinths and water peanuts, to provide a good place for the growth and habitat of Monopterus albus. When transplanting Alternanthera philoxeroides, it is best to remove the roots, wash them, and soak them in 5% salt water for about 10 minute to prevent harmful organisms such as leeches from being brought into the box with the grass.

7. The seedlings of Monopterus albus should be strictly disinfected before being put into the box, especially in July-September, when Monopterus albus is prone to disease, and the whole box should be sprayed with 1ppm bleaching powder every 20 days, and the sick Monopterus albus should be isolated in time. Find the disease, prescribe the right medicine in time, and minimize the loss.

8. During 65438+February every year, when the water temperature drops below 12 degrees, the feeding and growth of Monopterus albus basically stop. At this time, the eel in the cage will be arrested and listed.
