[0027] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] Reference Figure 1 , Figure 2 The fish egg hatching system proposed in this embodiment includes a hatching tank 100, a net 200, and a surging device 300. The hatching tank 100 contains water for hatching, the net 200 is adapted to float in the water within the hatching tank 100, and fertilized fish eggs are laid flat on the net 200. The surging device 300 is used to agitate the water within the hatching tank 100, causing the water to surge. The hatched fish fry fall to the bottom of the hatching tank 100 as the water surges. This fish egg hatching system, through the surging device 300, creates a surge in the water within the hatching tank 100 to simulate a natural environment, ensuring sufficient oxygen for the fish eggs, which is beneficial for hatching. Furthermore, the surging of the water prevents the fish eggs from accumulating.

[0030] It should be noted that the sticky net 200 is suitable for being suspended in the water in the hatching tank 100. In other words, the sticky net 200 can be suspended in the water in the hatching tank 100 through a suspension mechanism or a support mechanism, which will not be described in detail here.

[0031] It is understandable that the fish egg hatching system of this utility model can be used for hatching fish eggs of catfish and other fish species.

[0032] Reference Figure 1 , Figure 2 In some embodiments, the surging device 300 includes a circulation pump 310 and a water outlet pipe 320 connected to the circulation pump 310. The water outlet pipe 320 is positioned above the hatching tank 100, and the outlet of the water outlet pipe 320 is located on the water body in the hatching tank 100. The water pressurized by the circulation pump 310 flows out through the water outlet pipe 320, which can impact the water body in the hatching tank 100, causing the water body in the hatching tank 100 to surge, so as to simulate the natural environment, so that the fish eggs have sufficient oxygen, which is conducive to the hatching of the fish eggs and prevents the fish eggs from accumulating.

[0033] Reference Figure 1 , Figure 2 In some embodiments, the fish egg hatching system further includes a water level controller 400 and a circulation tank 500. The water level controller 400 is used to control the water level in the hatching tank 100. The circulation tank 500 is used to receive water flowing out of the water level controller 400, and a circulation pump 310 is located in the circulation tank 500. It is understood that when the surging device 300 creates a surge in the water in the hatching tank 100, the circulation pump 310 will continuously inject water into the hatching tank 100. If the circulation pump 310 uses an external water source, the water level in the hatching tank 100 will continuously rise, and the water in the hatching tank 100 will overflow from the side wall of the hatching tank 100, causing water waste and damaging the environment of the hatching site. By setting up the water level controller 400 and the circulation tank 500, the water in the hatching tank 100 can be recycled to save water resources.

[0034] Reference Figure 3In some embodiments, the water level controller 400 includes an inlet pipe 410, a connecting pipe 420, and an overflow pipe 430. The inlet pipe 410 is located near the bottom of the hatching tank 100. The overflow pipe 430 is located vertically inside the hatching tank 100. One end of the overflow pipe 430 near the bottom of the hatching tank 100 extends to the outside of the hatching tank 100. One end of the connecting pipe 420 is connected to the inlet pipe 410, and the other end is connected to the end of the overflow pipe 430 away from the bottom of the hatching tank 100. Water in the hatching tank 100 enters the connecting pipe 420 through the inlet pipe 410. When the fish egg hatching system is in use, circulating water is pressurized by the circulating pump 310 and injected into the hatching tank 100 through the outlet pipe 320, causing turbulence in the hatching tank 100 to simulate the natural environment. At the same time, as the circulating pump 310 continuously replenishes water to the hatching tank 100, the water level in the hatching tank 100 continues to rise, and the water level in the connecting pipe 420 rises synchronously. When the water level rises to the connection port of the connecting pipe 420 and the overflow pipe 430 away from the bottom of the hatching tank 100, the water in the hatching tank 100 is discharged into the overflow pipe 430 through the connecting pipe 420, and then into the circulation tank 500 through the overflow pipe 430. It is then pumped back into the hatching tank 100 by the circulating pump 310. This cycle creates turbulence in the hatching tank 100 while ensuring that the hatching tank 100 operates at a normal water level.

[0035] It is understandable that the water level controller 400 may also adopt other structures, such as setting an overflow port on the side wall of the hatching tank 100 to control the water level in the hatching tank 100 through the overflow port, which is not limited here.

[0036] Reference Figure 1 , Figure 2 In some embodiments, the circulation tank 500 is equipped with a filter 510 to filter impurities and viscous substances in the water to keep the water clean and maintain the incubation environment.

[0037] It is understandable that the filter 510 can be a microporous plate filter, a sponge filter, etc., and the circulation tank 500 can be divided into two or more compartments, each of which is equipped with a filter 510, so that the circulating water passes through multiple layers of filtration, further improving the cleanliness of the water and optimizing the incubation environment.

[0038] Reference Figure 1 , Figure 2 In some embodiments, the fish egg hatching system further includes a frame 600, an incubation tank 100 and a circulation tank 500, both of which are located on the frame 600, and the circulation tank 500 is configured to allow water in the incubation tank 100 to be naturally injected into the circulation tank 500 via a water level controller 400.

[0039] Specifically, refer to Figure 1 , Figure 2In this embodiment, the hatching tank 100 is mounted on the frame 600, and the circulation tank 500 is mounted inside the frame 600 and located below the hatching tank 100. The water in the hatching tank 100 can flow into the circulation tank 500 along the water level controller 400 under its own gravity.

[0040] Reference Figure 1 , Figure 2 In some embodiments, the hatching tank 100 is provided with multiple hatching chambers 110, each of which is equipped with a net 200. The surging device 300 can agitate the water in the multiple hatching chambers 110, causing the water in the corresponding hatching chambers 110 to surge. By setting multiple hatching chambers 110 in one hatching tank 100, the space of the hatching chambers 110 can be reduced. The surging device 300 can cause the water in the hatching chambers 110 to surge under relatively low power conditions, which not only meets the needs of fish egg hatching but also saves energy.

[0041] It is understandable that multiple incubation chambers 110 can be interconnected or disconnected. When multiple incubation chambers 110 are interconnected, only one water level controller 400 needs to be installed.

[0042] When multiple incubation chambers 110 are not interconnected, each incubation chamber 110 is equipped with a water level controller 400 (e.g., Figure 1 , Figure 2 As shown, the overflow pipes 430 of each water level controller 400 are collected into an overflow manifold 440, and then discharged into the circulation tank 500 through the overflow manifold 440.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
