To build a breeding pond for interplanting Monopterus albus and Misgurnus anguillicaudatus, it is necessary to choose a place sheltered from the wind and sunny, with quiet environment and convenient water sources, using cement ponds or upper ponds, or nesting in cages in reservoirs, weir ponds, small ditches and rivers, with an area of 25 ~150 square meters. In case of intercropping in cement ponds, dealkalization should be carried out before the seedlings are released, so that the seedlings of Monopterus albus and loach seedlings can be released. If the soil pond is used for breeding, it is required that the soil is hard and the bottom of the pond is compacted. The depth of the pond is 0.8 ~1.5 meters. Whether it is a cement pond or a soil pond, the bottom of the pond should be filled with a 30 cm layer of fat mud, and the fat mud with more organic matter is the best, which is beneficial to the digging of the eel and the loach. When the pool is built, the inlet and outlet should be set, and the water depth should be kept at15 ~ 20cm. The inlet and outlet should be tied with fish nets to prevent eel and loach from fleeing. Thoroughly disinfect the culture pond with quicklime about 10 days before seedling release, drain the pond water 3 ~ 4 days before seedling release, and then inject new water. Seedling is the key to interplanting Monopterus albus and Misgurnus anguillicaudatus. It is best to choose artificially cultivated and domesticated deep yellow big spotted eel or golden small spotted eel as the seedling of Monopterus albus, but not variegated eel seedlings. 60 ~ 80 Monopterus albus seedlings per kg are suitable, and the stocking density is generally1~1.5 kg/m3. Monopterus albus seedlings will be released to loach seedlings at the ratio of110 after 20 days, and it is best to cultivate them in loach seedlings, because the survival rate of artificially cultured monopterus albus seedlings is high. To feed the compound feed, it is necessary to install the feed box first, and the feed table can be made of wood or plastic. The area depends on the size of the pool, and it should be 5 cm below the pool surface. After the rice field eel seedlings are released, no feed is fed for the first 3-6 days, and after the rice field eel adapts to the environment, feed is fed on the 4th-7th day, and it is best to feed at around 7 o'clock every afternoon. Artificial rearing of Monopterus albus and loach is mainly based on compound feed, and some earthworms, river snails and Tenebrio molitor are appropriately fed. The formula of self-made compound feed is: fish meal 2 1%, cake 19%, energy feed 37%, earthworm (dried) 12%, mineral 1%, yeast 50%, multivitamins 2% and binder 3%. Feeding1~ 2 times a day, using the principle of timing and quantification, the rice field eel seedlings with a tail weight of 20 grams can grow to 0.25 ~ 0.3 kg a year. Misgurnus anguillicaudatus mainly feeds on feces excluded by Monopterus albus and inexhaustible feed in the culture pond. Feeding wheat bran once a day can satisfy the loach's food intake. Scientific feeding and management from May to September is the peak season for the growth of Monopterus albus and Misgurnus anguillicaudatus. What should we do during this period? Diligent? And? Fine? , that is, patrol the pool frequently, manage diligently, and solve problems in time when found. Both Monopterus albus and Misgurnus anguillicaudatus lie in the daytime and come out at night, so we should carefully observe the growth dynamics of Monopterus albus and Misgurnus anguillicaudatus so as to take corresponding measures in time. At the same time, the water quality should be kept fresh, and the pH value should be between 6.5 and 7.5.
Doing a good job in disease prevention practice has proved that once Monopterus albus gets sick, the treatment effect is often poor. This requires farmers to prevent diseases first and treat diseases early. Bleaching powder with a concentration of 1-2 parts per million can be commonly spilled in the whole pool, and the whole pool can be disinfected regularly with Fenbingling and Monopterus albus, so as to prevent diseases, and crystal trichlorfon can be used for deworming in spring and autumn every year.
Through the introduction of the new method of breeding Monopterus albus, we now know that the benefit of interplanting Monopterus albus and loach is good, which is what we need to pay attention to when breeding at ordinary times, and we should also pay attention to the management methods when breeding at ordinary times, so as to promote the increase of benefits in many ways.
