How many jin does Monopterus Albus yield per mu?

Monopterus Albus scientific name eel, also known as snake fish, blood eel, Changyu, etc., is a freshwater fish of the family Monopterus Albus. Two species are distributed in China, one is the common Monopterus Albus, and the other is Monopterus Albus. It is distributed in Sichuan, Yunnan, Guizhou, Chongqing, Hunan, Hubei, Anhui, Henan and Liangguang. Let's take a look at how many jin Monopterus Albus produces per mu.

How many jin does Monopterus Albus yield per mu?

Monopterus Albus generally can produce 14,15kg per square meter, and the yield per mu (666.6 square meters) can reach 10000 jin, but the number of jin of Monopterus Albus per mu mainly has a lot to do with the way of breeding. At the same time, because Monopterus Albus is not prone to disease and grows fast, so there is still a certain guarantee in terms of yield.

How many seedlings per mu of Monopterus Albus?

1. One mu of field is directly farmed in the purse seine on all sides, which can imitate ecological aquaculture. The average square seedling is 1 kg per square meter, and if it grows well, 667 kg is released in one mu of field. If 2 kilograms per square meter, 1334 kilograms of seedlings can be released.

2. If you switch to a cement pond for soilless culture, you can release seedlings according to 2.5kg per square meter, that is, 1667 kg.

How to increase the yield of Monopterus Albus?

1. Choose the address: the Monopterus eel pond must be in a quiet, sheltered, sunny and near-water place. The size of the pool can be determined according to the number of seedlings to be raised. The pool wall should repair as many holes as possible so that the rice field eel can make holes and latent. The bottom of the pool uses soil containing more organic matter. The soil is soft and moderate and the thickness is about 15 cm. The modified ditches, canals and culverts must be silt-clearing. In addition, the height of the pool wall can not be less than 1 meter, conditional walls can be built to keep quiet.

2. Water release construction: after selecting the address, disinfect the whole pool with an appropriate amount of quicklime, release water after 7 to 10 days to create a natural environment, plant some floating plants in the pool, and decorate the pond with an appropriate amount of poplar and willow trees. For 10-20 days, there are 3 fish and shrimps per square meter, so that the pond is full of vitality, and pay special attention to avoid using well water. Because not only the oxygen content of the well water is low, but also many minerals in the well water can easily make the environment of the fish pond inconsistent with the surrounding environment. In addition, the water in the pool should be drained and irrigated frequently to make it active.

3. Batch stocking: after the Spring Equinox, some local wild eels were caught and put into the pool, so that they first "set up camp." If the farmers are not eager for success, stay for about 15 days, release a batch of parent eel, because of its strong fecundity, a release, can be caught continuously, 12 pairs per square meter is the best. In the future, farmers can be put in batches according to their bearing capacity, but the total quantity should not be more than 20 per square meter.

4. Build a runway: Monopterus Albus living in groups in the pond are eager to find another "place to live" at night or in snow and rain. In order to let nature take its course, one or two "runways" can be built beside the pond (can be carried out at the same time in the pond). The runway can be recycled into the pond by cement pipes (sealed, no mud filling, the length is 2 to 3 meters), or lead to another fish pond, so that the wild nature of Monopterus Albus can be brought into full play and growth is promoted. If possible, you can also use the runway to irrigate the rice field eel to play and strengthen its physique.

5. Feed well: Monopterus Albus grows fastest at the turn of spring and summer, and can be fed with snail meat, earthworms, mussel meat, fly maggots, borers, animal offal and so on. In autumn, in addition to the above feed, properly feed some plant feed such as wheat bran, cooked wheat, vegetable leaves and duckweed. Do not feed too much or deteriorate feed. You should choose to eat at a fixed place, when the sun goes down and at noon in June.

6. disease prevention and treatment: local wild ricefield eel is the best (because it adapts to the environment) when stocking, do not put in one time, do not throw in the traumatic eel body, lest infect the bacteria to get sick and die, or even die in the whole pond. The eel seedlings are washed with bleach (10 grams per meter of water) before entering the pool. It is found that there are yellow spots on the belly of Monopterus Albus in the pond, which can be washed with cupric sulfate solution (8 grams per meter), but the new water must be changed after 1 hour.
