1. Select young eels to observe the body surface: the surface of eels is rotten with red blood clots, which is skin rot; The tail is white and fluffy, and it is water mold; The head is generally emaciated, even stiff, curly and trembling, which is a parasitic disease in the body; The anus is inflamed and inflamed, which is enteritis. In addition, young eels with weak body, little mucus and floating head are all bad eels and should be eliminated.
2. Disinfection of ponds: Before planting seedlings, the ponds should be completely disinfected. After the cement pool is soaked in quicklime water for 3 ~ 7 days, it is best to soak it in clean water for 15 ~ 30 days to make moss grow on the bottom of the pool. After disinfection, the loach was put into the pool for disinfection detection. If the loach floats, swims wildly in the water or dies within 1 ~ 4 hours, it shows that the disinfection in the cement pool has not achieved the effect. Disinfection soaking time should be extended.
3. Spreading nets and planting grass: raising eels in cages is inseparable from aquatic plants. Aquatic plants have the functions of shading and attaching Monopterus albus. Water hyacinth and rattan are generally selected as varieties. The manure of Monopterus albus is just the fertilizer for aquatic plants. Aquatic plants generally account for about 70% ~ 80% of cage or cement pool.
4. Domesticate the food under the seedlings: the trick of the seedlings is to look at the weather. Pay attention to the weather changes 5 ~ 7 days in advance to ensure that the seedlings are sunny; The water temperature is stable at around 25 degrees Celsius; The temperature difference between day and night does not exceed 5 degrees; The maximum water temperature does not exceed 35 degrees; Except the pregnancy and spawning period of Monopterus albus. When these conditions are met, all seedlings can be planted.
5. Under the classification of large and small fry, domesticating food is very important for the future growth and survival of Monopterus albus. After sowing for 3-5 days, young eels that don't open their mouths to eat or don't open their mouths much should be treated in time. Domesticated eel fry can be fed without bait for two to three days before entering the pond, and then fed at a later stage. The bait can be composed of maggots, earthworms, snail meat and feed.
6. In the process of taming food, it is best to do three things: first, listen to whether the eels eat evenly; Second, see how many eels eat with their mouths open; Third, observe the remaining amount of bait the next morning, whether the eel is abnormal, and whether the eel leaves the aquatic plants for activities during the day.
