The method of preventing cheating by purchasing rice field eel seedlings

Spring is a good time to raise eels and buy seedlings. In recent years, the market of Monopterus Albus is good, and the price is constantly rising. Every winter, there is basically no price in the market, so many people are investing or preparing to invest in raising Monopterus Albus. When choosing and buying rice field eel seedlings, you must be on guard against the following phenomena so as not to be deceived.

First, the number of artificial domestication and cultivation of wild rice field eel seedlings as artificial breeding seedlings is limited, and there are not many real artificial domestication and cultivation of rice field eel seedlings in China. Many frying units use the wild rice field eel seedlings purchased on the market as artificial breeding seedlings. There are more than 20 species of Monopterus Albus in China. The real domesticated seedlings of Monopterus Albus are deep yellow spot eel or golden small spot eel, and other varieties are not suitable for artificial breeding. Wild ricefield eel is mostly mixed color eel or gray light ricefield eel.

Second, use ordinary rice field eel seedlings as "extra large eel" and "hybrid eel" many stir-fry units, use domestic common rice field eel seedlings as "Thai extra large eel" and "hybrid eel", and claim to purchase their so-called "extra large eel" seedlings. The seedlings can grow 500g ~ 1000 grams in 3 months to 5 months, and the investment in 20 kilograms of seedlings can earn 100000 yuan a year. The author has been engaged in the research of rice field eel culture for many years and has been deceived many times. The conclusion is that such efficient culture can not be trusted. At present, there is no "hybrid eel" or "extra-large eel" in China, and the Thai eel really imported from Thailand is not suitable for the climatic conditions of our country. According to the survey, no one has succeeded in raising "extra-large eels" or "hybrid eels".

Identification method 1: the high quality seedling is dark yellow eel with dark yellow surface color, body shape and black spots. The seedling was domesticated artificially and was raised to masculinity with compound feed. 20 grams of seedlings can grow to 150 grams ~ 250 grams after 5 ~ 6 months. The body weight of other varieties of eel seedlings was less than doubled after 5 ~ 6 months, and some of them were even less.

Method 2: under the premise of regular, quantitative and fixed point, the compound feed or earthworms of Monopterus Albus were fed in the compound feed test method, and the really domesticated high-quality seedlings of Monopterus Albus can eat normally. It is impossible for wild rice eel seedlings or rice field eel seedlings with poor physique to eat formula feed or earthworms. When buying rice eel seedlings, you must go to the regular breeding farm, do not take rice field eel seedlings that do not feed.

Method 3: drug flooding screening method: soak rice field eel seedlings with 6 grams of copper sulfate per liter of water, or soak rice field eel seedlings with eel disease spirit by adding 10 grams of this medicine per cubic meter of water for 15 minutes. The high-quality rice field eel seedlings move regularly in the potion and end up in a static state. The seedlings of yellow eel of poor quality are the opposite to those of rice field eel with disease and injury.

Method 4: seedling price discrimination method Rice eel seedlings and other seedlings, the price of seedlings should be fair and reasonable, now the market commodity ricefield eel (Datiao) about 40 yuan per kilogram. Because the seedling needs a certain time and equipment in the process of cultivation, the price of the seedling is about 20% higher than that of the adult ricefield eel, which is a normal and reasonable price. Some fried seeds "companies" fried rice field eel seedlings to about 100 yuan per kilogram, while others even as high as 160 yuan, which is completely against the laws of nature.

But the seedlings whose price is lower than the market price should also be careful. Friends who are investing or preparing to invest in the cultivation of ricefield eel should learn more about breeding, explore more experience, and examine more formal manufacturers, so that the advantages and disadvantages of ricefield eel can be distinguished, and the breeding will be smooth.
