Catfish breeding method

Abstract

The invention discloses a catfish breeding method. The catfish breeding method comprises the steps that a breeding pond is arranged to have the area of 5 mu and the depth of 1.5 m, multiple oxygen increase devices are arranged in the breeding pond, and a layer of river mud of 20 cm is arranged at the bottom of the pond; comprehensive disinfection and sterilization are conducted on the breeding pond in 10 days before fry putting, fries are cleaned by using potassium permanganate during fry putting, and 2500 fries are put in the breeding pond per mu; a fodder and a green fodder are mainly adopted, feeding is performed for one time every day, feeding is performed for one time every half a month in winter, disinfection liquid is scattered to the whole pond at regular intervals, and ritodrine and other drugs can be mixed in the fodders to serve as a bait for treatment; starting for oxygen increase is performed every day for 2 hours, 1 / 3 of pond water is replaced every week, coarse salt is put, the transparence of the pond water is kept to be 30-40 cm, quick lime is scattered to the pond water every month, and aquatic plants are put in the fish pond every two months, wherein the putting amount of the aquatic plants is 10-15 kg per mu. By the adoption of the catfish breeding method, a water body environment can be improved, and the farming cost of farmers can be also reduced.

Description
