Controllable environment-friendly type fish culture box

Abstract

The invention relates to a controllable environment-friend fish box, which is formed by a floating support, a box, and a box bottom. The floating support comprises a floater, a support, a suspending ring, and a hook of fish box. The box comprises a frame, a mesh plate, a leaf side baffle plate, a suspending plate, a positioning plate, a lifting ear, a floating cylinder, a support of floating cylinder, a gas tube, a gas frame, and an aeration disc. The box bottom comprises a drainage groove, a hook of drainage groove, and a drainage tube. The frame of the fish box is arranged with outside leaf side baffle plate. The fish box mesh plate is arranged around the box and at the bottom. The floating cylinder, the gas frame, and the aeration disc are concentrically connected, via the support of floating cylinder to be fixed at the center of frame of fish box. The box bottom is arranged with the reverse-taper drainage groove, which is connected to the fixing hole of positioning plate via the hook of drainage groove. The floating support is partly arranged with a floater arranged on the support. The hook of fish box is connected with the lifting ear of positioning plate. The invention has simple structure.

Description

technical field [0001] The invention relates to an intensive aquaculture device, in particular to a controllable and environment-friendly fish culture box. Background technique [0002] It is recognized in practice that the scientific farming of fish is of great importance in increasing fish production. In recent years, people have adopted multi-species breeding methods, widely used aerators to increase oxygen, increased stocking density in ponds and other methods, tapped the production potential of water bodies, and significantly increased the yield per mu of ponds. However, the natural water purification and oxygen dissolving capacity of aquatic organisms in fish ponds is limited. Using aeration devices such as aerators can improve water quality and increase the oxygen content of pond water, which can increase the breeding capacity. Fish excrement and a large amount of residual bait cause the deterioration of water quality, so the stocking density of fish in ponds cannot ...

AI Technical Summary

Problems solved by technology

Although industrialized fish farming has many advantages, due to the huge investment in breeding facilities and equipment, and the large investment in the breeding process, it is difficult to promote and implement it on a large scale, and it is impossible to carry out large-scale factory transformation of traditional fish farming ponds

Because the traditional breeding mode produces a large amount of residual bait and feces during the breeding process and cannot be effectively removed, it will cause great pollution to the water body of the farming pond, so the breeding capacity of the pond is restricted, and the use efficiency of the water body is still very low
