[0019] Next, in combination with the accompanying drawings and specific embodiments, the present invention will be further described. It should be noted that, on the premise of non-conflict, any combination of the following-described embodiments or technical features can form a new embodiment.

[0020] Embodiment 1: Please combine Figures 1 - 9 , The hypoxia stress experiment device for Chuzhou crucian carp includes a breeding mechanism 05 for breeding and an oxygen control mechanism 04 for oxygen control. By separating the oxygen control mechanism 04 from the breeding mechanism 05, the influence of noise and the like during the operation of the device on the fish population in the breeding mechanism 05 is reduced.

[0021] The breeding mechanism 05 includes an outermost breeding box 11. A plurality of stirring rods 22 are connected to one side of the breeding box 11. A partition plate 26 is fixedly connected inside the breeding box 11. A plurality of separation pipes 24 are connected to the bottom of the partition plate 26. A slow-flow pipe 18 connected to the oxygen control mechanism 04 is connected to the bottom of the breeding box 11. A circulation sleeve 23 connected to the breeding box 11 is arranged on the partition plate 26. The breeding box 11 selects points according to the size of the crucian carp, and at the same time ensures the density of the fish population inside to ensure the stability of the experimental parameters. The stirring rods 22 can automatically extend to stir the fish population, forcing the fish population to swim for different tests. The partition plate 26 divides the space. The excrement or impurities above are discharged to the bottom through the separation pipes 24 for collection, and then discharged through the slow-flow pipe 18. Through the control of the external water pressure, the circulation sleeve 23 realizes the overflow of water with different flow rates for replenishment.

[0022] The oxygen control mechanism 04 includes a circulation tank 16 connected to the slow flow pipe 18. Inside the circulation tank 16, there is a first filter tank 30 connected to the slow flow pipe 18. One side of the first filter tank 30 is connected to a circulation pump 44.

Oxygen is filled in the aeration tank 34 to supplement oxygen. Then, through the monitoring of the first detector 36, if the oxygen content is low, part of the water returns to the second filter tank 31 through the pipe 45 and circulates again. Then, it enters the second detector 38 through the pipe 37 for secondary detection. Finally, it re-enters the circulation sleeve 23 through the buffer tank 40 and the return pipe 17 for circulation.

The oxygen pipe 14 is connected to the external oxygen supply to aerate the water body and increase the oxygen content. The water in the transparent tank 32 enters the aeration tank 34 through the drainage pipe 55 and then is discharged through the pipe 33.

[0024] Both the rotating ring 50 and the flexible pipes 51 are provided with multiple aeration holes. Multiple exhaust pipes 15 are fixedly connected to the aeration tank 34. The aeration holes ensure the passage of gas, and the exhaust pipes 15 discharge the excess gas to ensure the water pressure inside the aeration tank 34.

[0025] Inside the circulation tank 16, there is a replenishment tank 39 fixedly connected. One side of the replenishment tank 39 is fixedly connected to a pipe 43 connected to the first filter tank 30. One side of the first detector 36 is connected to a functional pipe 21 extending outside the circulation tank 16.

[0027] A control sleeve 27 is fixedly connected inside the breeding box 11. A plurality of irradiation lamps 28 are fixedly connected to the control sleeve 27. One side of the control sleeve 27 extends to the outside of the breeding box 11. A plurality of air holes are provided on the control sleeve 27. One end of the control sleeve 27 extending to the outside of the breeding box 11 is connected with a pressure control pipe, and a pressure control valve is connected to the pressure control pipe. The air pressure inside the breeding box 11 can be adjusted through the pressure control pipe to ensure the stability of the parameters inside the breeding box 11. The irradiation lamps 28 provide supplementary light, and at the same time, the control sleeve 27 is also connected with a camera for real-time monitoring of the state.

[0028] A flexible sleeve 12 is connected to one side of the breeding box 11. A grasping hole communicated with the flexible sleeve 12 is provided on the breeding box 11. A transparent plate is provided on one side of the breeding box 11, and a sunshade curtain connected to the breeding box 11 is provided on one side of the transparent plate.

[0030] The implementation principle of the embodiment of this application is as follows: When starting to work, water is injected into the breeding box 11, and then the circulation pump 44 in the oxygen control mechanism 04 is used for pumping. The water flows through the slow flow pipe 18, the first filter box 30 and the second filter box 31 and then enters the transparent box 32. The first filter box 30 and the transparent box 32 initially purify the water body. After passing through the transparent box 32, the drainage pipe 55, the aeration box 34, the pipe one 33, the detector one 36, the pipe two 37, the detector two 38, and the pipe three 41, it enters the buffer box 40. At the same time, oxygen is input through the oxygen pipe 14 and highly efficient aeration is carried out through the air holes of the rotating ring 50 and the flexible pipe 51. The detector one 36 and the detector two 38 feedback data in real time. If the dissolved oxygen is insufficient, part of the water body is returned to the second filter box 31 through the pipe five 45 for secondary oxygenation treatment. Finally, the regulated water body is transported to the circulation sleeve 23 through the buffer box 40 and the return pipe 17 to form a closed-loop cycle. When the whole system is stable, the corresponding number of crucian carps is placed in the breeding box 11. The partition plate 26 and the bottom separation pipe 24 cooperate to achieve dirt separation, and at the same time, it is circulated and cleaned through the slow flow pipe 18.

[0031] The perturbation rod 22 can be adjusted to apply a controllable perturbation to the Chuzhou crucian carp group to simulate different swimming intensities. The control sleeve 27 and the irradiation lamp 28 maintain the stability of the cabin environment, ensuring the precise control of oxygen delivery and water quality parameters. The overall device reduces external interference through physical separation and automated monitoring, ensuring the efficient acquisition and repeatability of fish group behavior, physiological responses, and environmental data in the hypoxia stress experiment.

[0032] Example 2: Combined with Figures 1 - 10 , on the basis of Example 1, the further improvement in this example is that a support plate is installed at the bottom of the breeding mechanism 05 and the oxygen control mechanism 04. One side of the support plate is connected to a vertical vertical plate 02, and the bottom of the vertical plate 02 is connected to a horizontal plate 01 fixedly connected to the ground. One side of the vertical plate 02 is connected to an air supply pipe, and one side of the vertical plate 02 is connected to a plurality of connecting pipes 03. The connecting pipes 03 are connected to the oxygen pipe 14 through pipes. Through the support of the horizontal plate 01 and the vertical plate 02, multiple groups of oxygen control mechanisms 04 and breeding mechanisms 05 can be supported in cooperation, thereby enabling multiple groups of experiments to be carried out simultaneously and increasing the overall experimental efficiency.

[0033] Filter cotton is arranged in the vertical plate 02. One side of the horizontal plate 01 is connected to a water supply pipe. One end of the water supply pipe is connected to a hose, and the other end of the hose is connected to a replenishment pipe 20 connected to the breeding box 11. The non-return air in the air is filtered through the filter cotton, and water is supplied to the breeding box 11 through the water supply pipe to replenish the water that may be lost in the breeding box 11.
