Problems solved by technology

Seedlings are produced from January to November every year. However, due to the immature technology of eel seedlings transformed from wild eel seedlings into cultivable eel seedlings, there are problems such as low survival rate, unstable production and high risk. In practice, fishermen also came to the conclusion that the seedlings purchased from January to June cannot be used for breeding. The seedlings during this period are used for breeding, and the mortality rate reaches 100% within 3-15 days, even if the seedlings purchased from June to August When seedlings are used for artificial breeding, their survival rate cannot be guaranteed
As for why the eel seedlings produced from January to June could not be cultivated as seedlings in the past, and how to raise them as seedlings, no scientific and technical personnel have reported research on this aspect, and there is no way to solve this difficulty.

Embodiment 1

[0016] Embodiment 1: Breeding in pond cages.

[0017] 10 vinyl net cages, size 2 m * 2 m * 1.2m; water surface, 2 acres of pond; on March 25, the pond water was added to a depth of 1.5m, and fish were stocked, including 600 bighead carp and silver carp 100 fish, 200 grass carp, installed a 2KW water jet aerator; on April 5, hung the net cage in a 2-acre pond, and filled the net cage with 70-80cm of water; On April 10, a 50L microbial culture container was installed; on April 19, the faucet of the microbial culture container was opened, and the bacteria containing microorganisms entered the pond, and the water pump was continuously turned on to continuously pump water into the container, allowing it to flow into the pond; on April 25, ricefield eel seedlings were purchased 75 kg of seeds were put into 10 net cages at a rate of 7.5 kg per case; water earthworms were fed on April 28, and compound feed was added to water earthworms on the second day, and the compound feed and fish...

Embodiment 2

[0018] Embodiment 2: Cement pond breeding.

[0019] 2 cement ponds, size 10m*2m*1.5m; on April 3rd, inject water 50cm deep, stock fish, 25 bighead carp, 5 silver carp, grass carp do not stock, move into philodendron chinensis, equipped with inflatable Aeration machine 150W; 10L microbial culture container was installed on April 14, the tap of the microbial culture container was opened on April 20, and the flow rate was controlled by a micro-pump to allow the microorganisms to flow into the breeding facility; 30 kg of eel seedlings were purchased on May 3 and put into the cement pool; from May 5th, with the ratio described in Example 1, water earthworms were used to induce the eels to open their mouths, and then water earthworms were added with compound feed to gradually reduce water earthworms, replaced with fish meat, and increased compound feed. After 5 days, water earthworms were Replaced with fish meat, mixed with compound feed and fed, until May 25, the survival rate reac...

Abstract

The invention relates to a method for cultivating and domesticating monopterus fries, which comprises the following steps: 1) choosing the fries; 2) pre-processing cultivating facilities; 3) processing cultivating water quality; 4) inputting initial feed and domesticating with food; 5) inputting secondary cultivated fish; 6) equipping with oxygenation; 7) cultivating successfully when the feeding rate of mixed feed of the monopterus fries reaches 2% of the weight of the monopterus fries, and entering into regular cultivation. The entire cultivating process is without spraying disinfectant and using antibiotics; the cultivating method is easy to understand and learn; the monopterus fries are easy to cultivate after the domestication; the survival rate is high. The method also solves the difficult problem that monopterus wild fries caught from January to July can not be used for cultivating at present. The method cultivates the fries successfully, can save 50% of the fry cost, and can obtain remarkable economic benefit whether selling to other farmers to cultivate or employing people to cultivate continuously.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating and domesticating eel seedlings. Background technique [0002] At present, the eel breeding depends on natural fishing, and the production of natural fishing seed is limited. There are a lot of information about ricefield eel breeding technology, but according to these techniques, even the same pond and the same management personnel will have different breeding results, and the success of ricefield eel farming is accidental. Seedlings are produced from January to November every year. However, due to the immature technology of eel seedlings transformed from wild eel seedlings into cultivable eel seedlings, there are problems such as low survival rate, unstable production and high risk. In practice, fishermen also came to the conclusion that the seedlings purchased from January to June cannot be used for breeding. The seedlings during this period are used for br...
