The key to the cultivation of Monopterus Albus

Several key points in the cultivation of Monopterus Albus are "species should be selected", "water should be adjusted", "water plants should be planted", "bait should be just right", and "disease prevention should be done".

Prepare the seedlings of Monopterus Albus: the seedlings of Monopterus Albus mainly come from the artificial propagation of Monopterus Albus seedlings, but the number is relatively small at present. The key is to cultivate and selectively mature Monopterus Albus seedlings, and then use artificial insemination to hatch the same fish by injecting oxytocin. Semi-artificial method, without artificial insemination, let them spawn naturally after injecting spawning agents and then hatch with domestic fish. From May to September, natural seedlings were collected and incubated in 25 ℃ ~ 30 ℃ water after searching for foam-gathered spawning nests in paddy fields, ditches, lake shoal weed areas or adult eel culture ponds. Cultivation of eel seedlings: eel seedlings should be cultivated in a small cement pool with deep 30px~1000px, and the soil at the bottom of the pond should be covered with 125px, which can be sterilized with "Jingbo strong chlorine essence" or quicklime cleaning pond; apply organic fertilizer or "amino acid fertilizer paste" or "fat spider treasure" according to 0.5kg / m2 ~ 1kg / m2 to cultivate water quality; transplant silk earthworms and breed aquatic plants such as water hyacinth or water peanut. Silk earthworms are the best bait for opening, and they can also be fed to zooplankton such as "red worms" or surimi, egg yolks, etc., or "soy milk feeding method"; the breeding density is 1000 / m2 ~ 2000 / m2, and the density should be reduced in the later stage. Pay attention to separate the size in time so as not to kill each other. Eel species selection: artificially cultivated eel species can be selected in the process of cultivation, but at present, most of them are purchased from the field, so we should pay more attention to the selection. Seedlings with body surface injury, electric capture (with blood stasis), hook catch, abnormal posture, abnormal body color and obviously less mucus can not be purchased. The common species of eel are: dark yellow spotted eel, dark yellow, irregular brown spots all over the body, this kind of fast growth, strong adaptability, large individual, is the best species for breeding; red eel, red body color, full of spots, good adaptability, fast growth, individual size, is the high quality object of culture. Light yellow fine spotted eel, with light yellow body color, small and fine speckled flowers, faster growth rate and better adaptability, because it is the main cultivated species at present, because it comes from a wide range of sources; others, such as cyan, light black, light white, etc., grow slowly, especially the cyan spotted eel almost does not grow big, and the adaptability is poor. Domestication: the cost and feed source should be considered in the artificial cultivation of eel, so it is necessary to domesticate in time, do not feed for the first 3 days, and then feed earthworms, yellow powder insects, mussel meat and fly maggots, and then gradually mix a small amount of other feed. The fixed feed ratio can be put into stable after 7 days. The time of domestication begins in the evening or at night, and if necessary, it can be fed during the day, and then slowly lead to the day, but Monopterus Albus is usually fed in the evening to facilitate its feeding at night. Eel species should be disinfected before putting in: use 3%-5% salt water or "Shidujing" or "povidone iodine solution" for 10 minutes. And pay attention to the temperature difference less than 2 ℃ to avoid catching a cold.
