Summary of the reasons for the failure of Monopterus Albus Culture

Raising Monopterus Albus is also one of the special aquaculture, and the economic income of raising Monopterus Albus properly is higher than that of raising fish, so in rural aquaculture, the number of households raising Monopterus Albus has been expanding in recent years, but many farmers who raise Monopterus Albus have failed, and there are many reasons for this. But in terms of technical problems, there are mainly the following eight categories. ① buys seedlings indiscriminately. The so-called "artificially farmed" seedlings or other so-called "high-quality" seedlings purchased by many farmers are actually collected wild seedlings, and these seedlings are not scientifically operated, such as temporary culture and multi-link storage, transportation, and so on. The mortality rate in breeding is 90% and 100%, so the purchase of seedlings must be carefully investigated and identified. In general, artificially cultured ricefield eel should choose and buy high-quality seedlings locally, which is not only economical, but also guaranteed in quality. ② does not choose varieties. From the appearance, there are deep yellow spots, red spots, light yellow fine spots, green gray fine spots and other types of rice field eel. Only by selecting the first two types can we have a faster growth rate and artificial culture can achieve ideal economic benefits. Mixed culture of ③. Mixed culture in the same pool, the small eel did not dare to compete for food, but the physique weakened or even died. When the bait is insufficient, the big eel swallows the small eel, so the large and small eel are mixed. Although the big eel grows fast, the total yield of the pond is low. The ④ pool is too deep. Because there is no swim bladder in Monopterus Albus, it can not float and stay in different water layers to breathe air. The pool water is too deep, Monopterus Albus needs to swim to the surface frequently to breathe, which consumes a lot of physical energy, affecting the normal life and growth. According to the body size and water depth of the eel, the water depth of the eel should be 20 cm, while the aquaculture of eel in the cage should fill the whole water tank in order to provide good habitat and breathing conditions for the eel. Manure was applied in ⑤ eel pond. The water body of eel pond is small, and the application of manure fertilizer can easily damage the water quality and induce diseases, so the loss of "improving water quality" outweighs the gain. ⑥ neglected to cultivate aquatic plants. Aquatic plants can prevent heat and cool down Monopterus Albus and purify water quality. Eel ponds without aquatic plants can not create a good ecological environment, breeding rice field eel is also difficult to succeed, or difficult to achieve high yield benefits. ⑦ feeds on a vegetarian diet. Some farmers feed Monopterus Albus with vegetarian foods such as wheat bran, vegetable cakes, bean dregs, rice and green vegetables. When they are seriously hungry and short of bait, Monopterus Albus will swallow a small amount, but the nutrition can not meet the needs of life activities of Monopterus Albus, let alone grow and gain weight. Over a long period of time, Monopterus Albus gradually lost weight and died. Monopterus Albus is a kind of benthic fierce carnivorous fish, which should be fed with animal feed or full-price compound feed. ⑧ refueling frequently. There are often breeders who change the types of bait for feeding because of the lack of food security. Monopterus Albus feed should have a certain stability, suddenly change the type of feed, Monopterus Albus is difficult to adapt and refuse to eat, which will affect the normal growth.
