Description

Smart Fish Farm The present invention relates to a smart fish farm that can provide stable water quality by automating a fish farming facility that includes circulating rearing water to increase dissolved oxygen levels, supplying feed, and cleaning a filtration tank for filtering rearing water. Generally, fish farms are structured to produce large quantities of fish in a small area, enabling the production of high-density fish while creating a stable water quality environment through various water treatment processes. In these high-density fish farms, rearing water is supplied through a means of water circulation; however, to compensate for the lack of oxygen in the water, water wheels, air diffusers, or even liquid oxygen, high-pressure oxygen, and oxygen generators are used, resulting in the operation of the farms using an extremely costly and inefficient method. Furthermore, when using pure oxygen such as liquid oxygen, carbon dioxide removal devices are used to reduce toxic carbon dioxide generated by fish in the water, or foam separators are used to remove dissolved organic matter. However, since these devices are expensive, they incur high costs, and there is a problem in that maintaining and operating them also requires significant expenses. In light of this, Public Patent No. 10-2011-0090665 disclosed by the present inventor has developed an aquaculture system comprising a plurality of air lift devices, each comprising: a rearing tank; a partition wall located in the center of the rearing tank; a pipe having an air outlet with a portion of its upper end open and a fluid inlet with a portion of its lower end open; an air supply pipe supplying air from the upper end to the lower end within the pipe; and an air diffuser connected to the air supply pipe to disperse air into the lower end within the pipe, wherein the air outlet and the fluid inlet are formed in opposite directions within the pipe, and a plurality of air lift devices are arranged in parallel in one area relative to the partition wall such that the air outlet of the air lift device faces a first direction, and a plurality of air lift devices are arranged in parallel in the other area relative to the partition wall such that the air outlet of the air lift device faces the opposite direction of the first direction. The purpose is to provide a fish farm that is equipped with an integrated structure and capable of providing stable water quality, based on the technical details of the aquaculture system described above. FIG. 1 is a plan view showing an overall configuration example of a smart fish farm according to the present invention. FIG. 2 is a planar example diagram showing the circulation of rearing water and the generation of rotational water flow in a smart fish farm according to the present invention. FIG. 3 is a side cross-sectional view showing an overall configuration example of a smart fish farm according to the present invention. FIG. 4 is an enlarged plan view showing a tank portion applied to a smart fish farm according to the present invention.
