Experience of overwintering and seed conservation of cultivated ricefield eel

Practice has proved that good overwintering and seed conservation of Monopterus Albus can ensure high yield and harvest in the coming year.

Harvesting Monopterus Albus: cultivated Monopterus Albus should be harvested in Qingtang before overwintering. The collection methods are as follows: 1. A number of eel cages made of bamboo are used to put baits such as pig liver and earthworms around the pond or at the bottom of the pond, which can be taken at night and in the morning, which can capture more than 80%. 2. Put a net sheet of 2mur4 square meters in the water, place the bait that Monopterus Albus likes to eat, then cover the Reed mat or straw bag and sink to the bottom. After about 15 minutes, lift the four corners quickly, lift the Reed mat or straw bag, and you can collect a large number of Monopterus Albus, with an initial capture rate of about 90%. 3. Dry pond mud control: before overwintering, when most of the rice field eel is lurking in the soil surface, the pond water can be drained and mud can be turned thoroughly to catch the eel. Choose parent eel: the male and female parent eel reserved for breeding should be at least one winter age, strong, disease-free, fast swimming and bright body color. The body length of female parent eel is about 20ml 30cm, and that of male parent eel is 40cm. The suitable retention ratio of male and female is 2:1. From March to April next year, the selected parent eel can be spawned and reproduced by intensive feeding. Keep enough eel species: when collecting rice field eel, we should not only sell some of it, but also keep enough small eel as seedlings according to the scale of production in the coming year. Generally, each square meter pool should prepare about 25 grams of small eel 5Mel 6 kilograms, which will be kept for next year's breeding. Eel species should choose small eels that are golden or brown on the back and are healthy and disease-free. Overwintering protection: it should be strictly protected from November of that year to February of the following year. Methods: 1. Overwintering with water. Leave a certain depth of water in the yellow eel pond to ensure that the cold does not freeze in the end. In this way, Monopterus Albus can sneak into the depths of the cave in the bottom of the pond to spend the winter. If the temperature is high, you can go out to breathe and hunt during the day. 2. Drain water through the winter. Drain the pool water and keep the soil moist. In order to prevent freezing, the pool can be covered with a layer of straw, straw bags and other warmth to prevent freezing. This method is applicable to the eel ponds to be collected before and after the Spring Festival.
