Zusammenfassung: | The invention discloses a summer-pond-leaving-young-tor-brevifilis double-pond breeding method. The summer-pond-leaving-young-tor-brevifilis double-pond breeding method includes the following steps: A, repairing and maintaining a storage pond, wherein the storage pond provided with a high-power heating device is a rectangular cement pond; B, disinfecting a breeding pond, and enriching water; C, managing the storage pond, wherein micro flowing water is held in the storage pond, the young-tor-brevifilis density ranges from 4,000 to 4,500 per square meter, eight to ten powdery yolks are fed into each pond every day, and water changing is carried out at the time one hour after feeding; D, managing the quality of the water in the breeding pond, wherein the micro flowing water state of the young-tor-brevifilis breeding pond is kept, young tor brevifilises are placed into the breeding pond at eight o'clock to nine o'clock in the morning of a fine day, and 25,000 to 35,000 young tor brevifilises are placed in every 667 square meters; E, managing feeding of the breeding pond, wherein when the body length of the young tor brevifilises is 1.5 cm, manual taming feeding is carried out through adult eel feed, feeding is carried out at eight o'clock in the morning and four o'clock at nightfall every day, and 48 g to 52 g of adult eel feed is fed in every 667 square meters each time; when the young tor brevifilises grow to be 2 cm in length, artificial feed is fed, and the everyday feeding amount is 6% to 8% of the weight of the young tor brevifilises. |
