Ecological Propagation techniques of cultivated Monopterus Albus
1. Induced ripening and spawning of parent eel: after late May, when the water temperature reached 25 ℃, each parent eel was injected with LRH-A (luteinizing hormone-releasing hormone) 12.5mg, 0.5ml dose 0.5ml to promote gonadal maturation, and 7 days later, DOM 0.5ml or LRH- was injected.

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. Some eel cages are made of bamboo, and baits such as pig liver and earthworms are placed around or at the bottom of the pond at night.

1. The selection and cultivation of parent eel as breeding eel requires strong physique and lively swimming. The body color should be thick black mud, yellowish brown or black flowers, green brown. According to the source of parent eel, the wound caught in cage on the same day was smaller. Monopterus Albus has the characteristics of sexual transformation. Monopterus Albus is basically female at the age of 1 and 2, the proportion of males increases gradually after spawning at the age of 2, and is basically male at the age of 6. In the non-spawning season, it is difficult to distinguish between male and female, generally based on body length and weight, with a body length of 37cm to 50cm and a body weight of 7.

How to choose to kiss eel
If we want to choose the seedlings with more eggs, high fertilization rate, emergence rate and good quality, we must choose the rice field eel with a certain age, weight, strong physique, no serious disease and trauma as the parent eel. In the non-breeding season, it is difficult to distinguish between female and male eel in appearance, and usually stay on the basis of body length. Most of the ricefield eels are female when their body length is 20 cm-35 cm, and most of them are male when their body length is more than 45 cm. Under normal circumstances, you can choose to stay at 3:1 according to the above two body length groups.
