[0002] Fish fry stocking boxes in aquaculture protect fry from attacks by larger fish, reducing losses due to predation or competition. These boxes concentrate fry in a specific area, facilitating feeding, disease prevention, and management for farmers. The moderate fry density within the boxes promotes healthy growth and development. Using fish fry stocking boxes increases fry survival rates and growth rates, thereby improving aquaculture efficiency.

[0003] Fish fry stocking boxes in aquaculture increase dissolved oxygen through water pump circulation and promote water exchange while protecting the fry through tank and filter design. However, some existing fish fry stocking boxes suffer from insufficient oxygen dissolution, leading to fry mortality due to inadequate dissolved oxygen in the water. Therefore, this proposed fish fry stocking box for aquaculture aims to address this problem. Utility Model Content

[0022] 1. In this utility model, the water pump is then turned on to extract the internal water. The water flows through the connecting pipe into the three-way pipe and through the three internal negative pressure pipes. First, it passes through the first-stage negative pressure pipe, where a negative pressure is generated through the small-diameter opening, drawing air into the water and increasing the oxygen content. When it passes through the second-stage negative pressure pipe, a negative pressure is generated again, and the air inlet further absorbs air into the water, increasing the oxygen content. The negative pressure is then released, allowing the oxygenated water to enter the fish fry tank, thus achieving water circulation and increasing the oxygen content in the water, which can ensure the survival rate of the fish fry in the tank.

One end of the water inlet pipe 6 is detachably connected to a T-connector 1 to facilitate the introduction of air. A primary negative pressure pipe 2 is fixedly connected to the inner wall of the T-connector 1. Negative pressure is generated through the small-diameter opening of the negative pressure pipe 2, drawing air into the water. In this process, to increase the oxygen content in the water, a secondary negative pressure pipe 3 is fixedly connected to the inner wall of the three-way pipe 1. The diameter of the secondary negative pressure pipe 3 is larger than that of the primary negative pressure pipe 2. The secondary negative pressure pipe 3 generates negative pressure, which is then introduced into the water through the air inlet 5, further increasing the oxygen content. A tertiary negative pressure pipe 4 is fixedly connected inside the three-way pipe 1. The diameter of the tertiary negative pressure pipe 4 is larger than that of the secondary negative pressure pipe 3, allowing the negative pressure to be released and facilitating the entry of oxygenated water into the fish fry stocking tank 8, further increasing the oxygen content of the water. The fish fry stocking tank 8 is made of... PUR polyurethane insulation material provides long-lasting insulation for up to ten hours. The openings of the primary negative pressure pipe 2, secondary negative pressure pipe 3, and tertiary negative pressure pipe 4 increase progressively to facilitate negative pressure and oxygen absorption. A connecting pipe 9 is detachably connected to the outer wall of the three-way pipe 1 to facilitate water flow. An air inlet 5 is provided inside the three-way pipe 1 for air intake. A water pump 10 is connected to the outer wall of the connecting pipe 9, and a water pump pipe 12 is fixedly connected to the outer wall of the water pump 10 for pumping water from the fish fry tank 8. The inner wall of the fish fry tank 8... A water outlet 11 is fixedly connected to the outer wall of the fish fry release tank 8. A water-absorbing gauze 13 is fixedly connected to the outer wall of the fish fry release tank 8 to prevent the fish fry from being pulled out when pumping water. A fixing box 7 is fixedly connected to the outer wall of the fish fry release tank 8. A three-way pipe 1 is detachably connected to the inner wall of the fixing box 7 for fixing the three-way pipe 1. A heating device 21 is fixedly connected to the inner wall of the fish fry release tank 8 for heating the entire inside of the fish fry release tank 8 to a suitable temperature. A heating motor 22 is fixedly connected to the outer wall of the fish fry release tank 8 for controlling the heating device.

[0032] Reference Figure 1 , Figure 2 , Figure 3The batch fish fry release assembly includes a fish inlet 16, which is fixedly connected to the outer wall of the fish fry release tank 8 to facilitate the entry of fish fry into the tank. A fish fry release hopper 15 is fixedly connected to the outer wall of the fish inlet 16 for storing a large number of fish fry. A control motor 20 is fixedly connected to the top of the fish inlet 16 to control the rotation of two rotating rods 17. Two rotating columns 17 are fixedly connected to the inner wall of the fish inlet 16, and a switch door 18 is fixedly connected to the outer wall of the two rotating columns 17. The rotation of the rotating rods 17 drives the switch. The door 18 is opened and closed to control the quantitative release of fish fry. The top of the fish fry release tank 8 is detachably connected to a sealing door 19 to seal the fish fry release tank 8 and prevent heat loss. It can be removed when not needed. The other ends of the two rotating columns 17 are rotatably connected to the drive end of the control motor 20 to drive the rotating columns 17 to rotate. The inner wall of the fish fry release tank 8 is fixedly connected to the fish fry release port 14 to facilitate the entry of fish fry into the fish fry release tank 8. The other end of the fish fry release port 14 is fixedly connected to the inner wall of the fish inlet 16.

[0033] Working principle: Before releasing the fish fry, a large amount of water is poured into the fish fry release tank 8. The heating motor 22 is turned on, controlling the heating device 21 to heat the water inside. Then, the water pump 10 is turned on to pump out the water. The water flows through the connecting pipe 9 into the three-way pipe 1. It then passes through the three negative pressure pipes inside. First, it passes through the first-stage negative pressure pipe 2. The small-diameter opening of the first-stage negative pressure pipe 2 generates negative pressure, drawing air into the water and increasing the oxygen content. The diameter of the second-stage negative pressure pipe 3 is larger than that of the first-stage negative pressure pipe 2. When passing through the second-stage negative pressure pipe 3, negative pressure is generated again. The air intake 5 further absorbs air into the water, increasing the oxygen content. The diameter of the third-stage negative pressure pipe 4 is larger than that of the second-stage negative pressure pipe 3, which releases the negative pressure and facilitates the oxygenated water to enter the fish fry stocking tank 8, further increasing the oxygen content. Finally, the oxygenated water enters the fish fry stocking tank 8 through the water inlet pipe 6. When the water is sprayed into the fish fry stocking tank 8, the pressure difference causes water surface ripples, further increasing the oxygen content and achieving water circulation. This increases the oxygen content in the water and ensures the survival rate of the fish fry in the fish fry stocking tank 8.

[0034] When it is time to release fish fry, the fry are placed into the fry release hopper 15. The control motor 20 controls the rotating rod to open the switch door 18. Then the fry flow into the fry release tank 8 through the fry release port 14. After a certain period of time, the control motor 20 controls the rotating rod to close the switch door 18. The switch door 18 will generate resistance to push the fry away, preventing them from being harmed. After the switch door 18 is closed, the fry stop flowing in. After a period of time, the switch door 18 is reopened to release the fry in batches, which can avoid overcrowding during release, oxygen deficiency, and fry death.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
