The feeding pond of Monopterus albus should have certain wind resistance, sufficient light and high quality water source. According to the number of aquaculture, control the size of aquaculture ponds, then lay drainage and irrigation measures, and set barbed wire at the entrance and exit to prevent eels from fleeing. After the establishment of the aquaculture pond, the disinfection of the pond should be done well. First, fill the pond with water to see if there is any leakage. Then soak for 3 days and soak for about 4 times. After soaking, put soil and farmyard manure at the bottom of the pool, and then plant an appropriate amount of aquatic plants. It can not only adjust the temperature of the pond, but also let the eel rest, and its water level is kept at about 15 cm.
Step 2 stock fry
About a week before stocking fry, the pond should be disinfected and evenly sprinkled with quicklime. After disinfection, water should be injected into the pond, and the temperature of the pond water should not be too different from that before stocking. It is necessary to ensure the high quality and strong growth ability of eel fry, and adapt to the culture environment as soon as possible, and the size of all eel fry is not much different, otherwise it is easy to have insufficient food. Then the breeding density should be controlled according to the number and conditions of breeding. It is best to mix a small amount of loach, which can effectively improve dissolved oxygen in water.
3. Breeding management
The food intake of Monopterus albus will change with its growth stage. Therefore, in order to meet the nutritional needs of Monopterus albus, the feed should be adjusted reasonably. For example, for a week, the main feed for eel fry is plankton, so it is necessary to improve the fertility of water and cultivate plankton. Monopterus albus has the habit of eating at night, so we need to feed it properly every evening in the early stage of breeding. Then, with the growth of Monopterus albus, the feeding time can be advanced appropriately. After about two weeks, feed it three times a day to ensure sufficient nutrition for the growth of Monopterus albus.
4. Water quality regulation
Water quality is a point that we need to pay attention to in the process of breeding. Because the weather, bait feeding and eel feces will pollute the water quality, it is necessary to adjust the water quality regularly. Pay attention to remove the unfinished bait of Monopterus albus in time after each feeding. It is necessary not only to prevent water pollution, but also to prevent eel from eating by mistake due to bait deterioration. We should adjust the frequency of changing water according to the change of seasons, such as changing water once a week in spring and once every four days in summer. And inject new water at any time to ensure water quality.
