Preparation and some skillful techniques for overwintering of cultivated Monopterus Albus

After entering October, those engaged in eel farming should pay attention to it, because in another month, it will almost reach the hibernation period of eel. Therefore, before eel overwinters, what should we do for eel?

1, to let eel full, have enough physical fitness;2, to manage the water, a lot of black and algae water to cure;3, to kill the insects on the peanut, you can also spread straw on the peanut to keep warm;4, to prevent enemies, water rats, birds, thieves. In addition, eel winter there are some clever ways. 1. Overwintering with water. Monopterus albus is a cold-blooded fish with variable temperature and strong adaptability to the environment. When the temperature drops below 10℃ (growth temperature 15-30℃), it rarely eats and hibernates in the cave. At this time, in order to safely overwinter Monopterus albus, the water level of the culture pond should be increased to 30-50 cm to ensure that the water temperature at the bottom of the pond in winter is above 0℃. If the pond is full of ice, the ice must be opened every day to prevent the eel from lacking oxygen. 2. Dry pond overwintering method. Drain the pond water when the water temperature is below 10 DEG C, ensure that the soil at the bottom of the pond is wet, and cover a layer of straw or wheat straw or corn stalk on the surface of the pond soil with a thickness of 30 cm. 3. Indoor overwintering method. When the temperature is below 10 DEG C, the finless eel cultured in the pond is transferred indoors for overwintering, the finless eel is put into a pond or a bucket according to the proportion of 1 kilogram of finless eel and 2 kilograms of water in the indoor pond or bucket, the water is changed once a day, and the indoor temperature is ensured to be between 2 and 5 DEG C. 4. Plastic greenhouse overwintering method. When the water temperature in winter is lower than 12℃, the effect of plastic greenhouse is also very good. The water level of the pond in the plastic shed is slightly higher than that of the breeding water level, and the temperature in the shed is guaranteed to be between 2 and 8℃. When the temperature is highest at noon every day, open the vent hole of the greenhouse to make the air in the greenhouse fresh, and install the vent hole at the top of the greenhouse to prevent the eel from dying of hypoxia.
