Stagewise fish pond with automatic catching function for freshwater aquaculture

Abstract

A graded automatic fish farming pond for freshwater aquaculture, comprising: a fish pond, an oxygen delivery device, and a graded fishing device, wherein, the graded fishing device includes at least two gathering nets, and the gathering nets Once set on the inside of the adjacent gathering net, the mesh density of the gathering net increases from the inside to the outside, and the surface of the fish pond is provided with a control panel, and the control panel passes through the circuit and Each layer of folding net is connected. The invention can increase the oxygen content in the fish pond through the oxygen increasing tube; when the fish in the fish farm are mature, the control panel can be used to control the layer-by-layer folding nets, and the fish of different sizes can be fished in the corresponding The net is gathered, and finally the water in the fish pond is discharged through the water-permeable pores, and the fish fry remaining after being caught by the net are gathered for fishing.

Description

technical field [0001] The invention belongs to freshwater aquaculture equipment, in particular to a freshwater aquaculture graded automatic fishing pond. Background technique [0002] The dissolved oxygen content of the water body is the main limiting factor of the density of fish farming. In high-density fish farming, the continuous flow and exchange of the fish farming water body provides dissolved oxygen for the fish and takes away metabolic waste. [0003] At present, there have been many improvements in oxygen utilization and breeding density in industrialized high-density flowing water fish farming, but the equipment is complicated, the oxygen utilization rate is low, and the breeding density is difficult to further increase, and the relevant fish ponds still exist in the actual application process. Many problems, such as the need for manual observation and manual operation to supplement oxygen, and the difficulty in fishing and cleaning fish ponds. Contents of the ...
