Zusammenfassung: | The invention discloses a tor-brevifilis pond artificial aquaculture method. The tor-brevifilis pond artificial aquaculture method includes the following steps: A, repairing and maintaining an aquaculture pond; B, carrying out disinfection and water enriching, wherein dry-method disinfection is carried out through bleaching powder, water is added, and the bleaching powder is dissolved and diluted to be evenly scattered to the whole pond; after disinfection is completed, water enriching agents and micro-ecology preparations are added to be scattered to the whole pond; C, breeding fries, wherein at the time 20 days after disinfection, breeding is carried out in the early morning or at nightfall on a fine day, and the breeding density of the young tor brevifilises ranges from 3.5 to 4 per square meter; D, carrying out pond splitting management, wherein after pond splitting is carried out, chub fries with the sizes 30 per kg are bred, the breeding density of the young tor brevifilises ranges from 2 to 2.5 per square meter, and the breeding density of the chub fries ranges from 0.15 to 0.18 per square meter; E, carrying out feeding management; F, adjusting the water quality, wherein the water change frequency is one to two times per month, the water transparency of the aquaculture pond ranges from 30 cm to 40 cm, lime water is scattered to the whole pond one time per month, composite biological agents are scattered to the whole pond one time per month, and the dosage of the composite biological agents ranges from 7.5 g per square meter to 9 g per square meter; G, carrying out fishing. |
