Breeding equipment and method for improving disease resistance of grass carps

Abstract

The invention discloses breeding equipment for improving disease resistance of grass carps, and belongs to the technical field of grass carp breeding equipment. The breeding equipment comprises a collecting box, four sets of supporting legs are fixedly installed on the outer wall of the bottom of the collecting box, hydraulic cylinders are fixedly installed on the outer walls of the supporting legs, and hydraulic rods at the tops of the four sets of hydraulic cylinders are fixedly connected with a bottom plate; and open holes are evenly formed in the outer wall of the collecting box. Accordingto the breeding equipment, the grass carps are guided into the collecting box, the bottom of the collecting box is shielded through upward movement of the bottom plate, and small grass carps are driven out from the open holes, so that large grass carps stay in the collecting box, the grass carps are conveniently fished, and damage to the grass carps during fishing is reduced. Through communucation through through holes, the upper side and the lower side of the bottom plate are communicated, so that in the process that the bottom plate moves upwards to shield the bottom of the collecting box,the change of water flow at the bottom plate is small, the probability of disturbing fish schools in the collecting box is reduced, and the probability that the fish schools swim away from the bottomof the collecting box when the bottom plate moves upwards is reduced.

Description

technical field [0001] The invention relates to the technical field of grass carp breeding equipment, in particular to a breeding equipment and method for improving disease resistance of grass carp. Background technique [0002] In the process of grass carp breeding, in order to increase the disease resistance of grass carp, it is necessary to catch the farmed grass carp, catch the big fish, and keep the small fish in the breeding area, which can reduce the density of grass carp in the pond and improve the quality of grass carp in the pond. living environment, so as to enhance the disease resistance of grass carp. When fishing grass carp in breeding areas, it is generally fished by means of fishing nets. Grass carp squeezed together may easily cause damage or death of the caught grass carp. Therefore, we propose a breeding equipment and method for improving disease resistance of grass carp. Contents of the invention [0003] The object of the present invention is to provi...
