s1: purchasing healthy and alive eel fries at the bottom of 4 months to the beginning of 6 months, wherein the standard is 25-30/jin, temporarily culturing in a greenhouse, sterilizing by povidone iodine and/or thioether sand before temporarily culturing, resisting stress by using anti-excitant and liver relaxing, preventing common cold by using Ganmaoling granules, not feeding during temporarily culturing, and timely fishing out dead eel fries;
s2: the method comprises the following steps of erecting a water circulation layered eel culture system, placing a proper amount of eel nests and black plastic bags in each culture cavity (4) of a culture tank (1) for resting and shading finless eels, and simultaneously adding a proper amount of water into the culture tank (1) and a water tank (7);
s3: at the bottom of 6 months to the beginning of 7 months, the eel seedlings are transferred into a culture tank (1) for culture, and the stocking density is 3-5 jin/m2Meanwhile, a proper amount of the lion is put in, and then the water pump (14) is started to enable the water in the culture tank (1) and the water in the water tank (7) to form circulation, so that the water in the culture tank (1) is kept clean;
s4: opening with water earthworms and/or earthworms after eel fries are bred, gradually adding minced fillet after one week, gradually reducing the using amount of the water earthworms and/or earthworms, stopping feeding the water earthworms and/or earthworms after another week, gradually adding compound feed into the minced fillet until the ratio of the minced fillet to the compound feed is 1:1, and gradually increasing the feeding amount by 5-6% after stable feeding;
s5: during the culture process, the residual bait is cleaned every day, and one or more of nitrobacteria, bacillus and lactic acid bacteria are added into the bacteria culture cavity (9) of the water circulation module every other week in the feeding period, so that the water quality is improved, and the physique of the finless eel is enhanced.
