[0002] The red porcini belongs to the order Siluriformes and family Crotalidae in the class Osteichthyes. It is a valuable and endangered freshwater benthic fish, mainly distributed in the Yuanjiang River in my country, the Red River and Ma River in Vietnam, and northern Laos. It feeds on animal matter and is a migratory river fish, laying drifting eggs during reproduction. Due to problems such as blocked migration channels and habitat shrinkage caused by water resource development, the population growth of red porcini is limited, and artificial breeding techniques are urgently needed to maintain its population size.

Moreover, red pomfret have strong territorial behavior and are prone to fighting and stress when lacking hiding space, which affects the survival rate. In addition, existing aeration systems have problems with uneven water flow or strong current impact, which does not conform to the benthic habits of red pomfret that prefer warm water flow. To address the aforementioned problems, this utility model provides an artificial breeding device for red porcini. Summary of the Invention

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5This utility model provides a technical solution for an artificial breeding device for red pomfret: an artificial breeding device for red pomfret includes a breeding box 1 and multiple support legs 11 arranged in an array at the bottom of the breeding box 1. A water circulation oxygenation system 2 is installed on the breeding box 1 to provide uniform dissolved oxygen and gentle water flow inside the breeding box 1. The water circulation oxygenation system 2 includes a water pump 21 installed at the upper middle part of the breeding box 1 via a bracket. The input end of the water pump 21 is connected to a drain pipe 22. One end of the water inlet pipe 23 extends tangentially into the breeding box 1 to form a vortex. The output end of the water pump 21 is connected to the water inlet pipe 23 and a branch pipe 25 via a three-way pipe 24. One end of the drain pipe 22 passes through the middle section of the breeding box 1 and is connected to its interior. When the water circulation oxygenation system 2 is working, the water pump 21 starts and draws water from the middle section of the breeding box 1 through the drain pipe 22. The water is then diverted through the three-way pipe 24 to the water inlet pipe 23 and the branch pipe 25. The water inlet pipe 23 enters the water tangentially to form a vortex, promoting water mixing.

[0018] A control valve 26 is also installed on the branch pipe 25, and the branch pipe 25 is fixed to the outer wall of the breeding tank 1 by the pipe bracket. The other end of the branch pipe 25 is connected to the jet injector 27, and the other end of the jet injector 27 is connected to the annular pipe 28. Multiple guide oxygenation pipes 29 are distributed in a circular array on the inner side of the annular pipe 28. The annular pipe 28 is installed on the outer side of the bottom of the breeding tank 1 by the fixing bracket, and the annular pipe 28 is connected to the jet injector 27 and the guide oxygenation pipes 29. The other end of the guide oxygenation pipe 29 passes through the bottom of the breeding tank 1 and is connected to its interior. The guide oxygenation pipe 29 is set horizontally and inclined. The flow rate of the branch pipe 25 is adjusted by the control valve 26. After the water flows into the jet injector 27, it mixes with the air to generate microbubbles, which are distributed to each guide oxygenation pipe 29 through the annular pipe 28 and evenly sent to the bottom of the breeding tank 1 to achieve oxygenation. The outer wall of the breeding tank 1 is located below the water pump 21 and has multiple drain outlets 220 arranged in a straight array. The inner wall of the drain outlet 220 is provided with internal threads. One end of the drain pipe 22 is screwed into one of the drain outlets 220 through a sealing joint to achieve a seal. The remaining drain outlets 220 are all threaded with sealing caps. Drain pipes 22 can be connected to drain outlets 220 at different positions to facilitate control of water level and flow rate, forming a "top in, middle out" circulation mode to avoid bottom disturbance. This principle is based on fluid dynamics and oxygen mass transfer theory to ensure uniform distribution of dissolved oxygen and adapt to the benthic habits of the red pomfret.

[0019] The lower section of the rearing box 1 contains multiple layers of perching boards 4 and perching tubes 5 arranged in a circular array with staggered layers. The perching boards 4 and perching tubes 5 are detachably connected to the rearing box 1. The rear ends of the perching boards 4 and perching tubes 5 are equipped with positioning screws 6. The inner wall of the rearing box 1 is provided with positioning screw holes 61 corresponding to each positioning screw 6. The perching boards 4 and perching tubes 5 are fixed to the rearing box 1 by screwing the positioning screws 6 into the positioning screw holes 61. The positioning screws 6 at the rear ends are threadedly connected to the positioning screw holes 61 on the inner wall of the rearing box 1, achieving detachable fixing. This allows for easy adjustment of the number of layers and spacing of the perching boards 4 and perching tubes 5 according to the rearing scale and the size of the red pufferfish, adapting to the needs of different rearing stages.

[0020] The surface of the perch board 4 is designed with an uneven structure to mimic rock crevices, and the perch tube 5 is a tubular structure used to simulate natural caves. Its uneven surface and tubular structure provide independent perch space for the red-billed catfish, reducing mutual interference. Through multiple layers of detachable perch boards 4 and perch tubes 5, the rock crevices and caves of the red-billed catfish's natural habitat are simulated. The vertical space is used to increase the breeding density per unit area, and the staggered design reduces direct contact between fish and reduces fighting caused by territorial behavior. Its principle is based on the environmental enrichment theory in animal behavior, which reduces stress by providing hiding places.

[0021] The breeding box 1 has a circular upper part and a conical bottom. The bottom of the breeding box 1 is connected to a sewage pipe 3. A sewage valve 31 is also installed on the sewage pipe 3. One end of the sewage pipe 3 extends to the center of the bottom of the breeding box 1 and is connected to the bottom of the box. When the sewage valve 31 is closed, it can store breeding water. When it is opened, it can discharge the feces and uneaten feed deposited at the bottom.

[0022] The working principle of this utility model is as follows: When in use, according to the red arowana breeding specifications, such as juvenile fish or adult fish, the perching board 4 and perching tube 5 are fixed in the middle and lower section of the breeding box 1 by screwing the positioning screw 6 into the positioning screw hole 61, and adjusted to a multi-layered staggered distribution. Then, the perching board 4 with the simulated rock crevice concave and convex structure simulates the natural rock surface, and the tubular perching tube 5 simulates the cave to simulate the formation of an independent perching space for the red arowana. Then, water suitable for the survival of red arowana is added to the breeding box 1 to complete the pre-breeding preparation. During the breeding process, the water pump 21 installed at the upper middle part of the breeding tank 1 is started. The water pump 21 draws water from the middle section of the breeding tank 1 through the drain pipe 22 at the input end. After being pressurized by the water pump 21, the water is divided into two streams through the three-way pipe 24 at the output end: The first stream of water enters the inlet pipe 23. Since the inlet pipe 23 extends tangentially into the breeding tank 1, the water flows along the tangential direction of the tank wall, forming a slow swirling flow inside the tank. This promotes uniform mixing of the upper and lower layers of water, avoids oxygen stratification, and prevents strong flow impact. The second water flow enters the branch pipe 25. The flow rate can be adjusted by the control valve 26 on the branch pipe 25. After the water flows into the jet injector 27, air is drawn in by the jet negative pressure principle, forming a water and air mixture and generating microbubbles, which increases the oxygen contact area. The mixed flow then enters the annular pipe 28 installed on the outside of the bottom of the breeding tank 1. It is evenly distributed to the guide oxygenation pipes 29 in the inner circumferential array through the annular pipe 28. Since the guide oxygenation pipes 29 are set horizontally and inclined and penetrate the bottom of the breeding tank 1, the microbubbles are smoothly delivered into the bottom area of ​​the tank along the inclined direction, realizing precise oxygenation of the benthic area without dead water flow. Furthermore, the outer wall of the breeding tank 1 has multiple internally threaded drain outlets 220 below the water pump 21. The pumping height can be adjusted by replacing the drain outlets 220 connected to the drain pipe 22, thereby controlling the circulation flow rate and the water level in the tank. For example, a higher drain outlet can be selected during the juvenile stage to reduce the circulation flow rate, while a lower drain outlet can be selected during the adult stage to improve the water renewal efficiency. The remaining unused drain outlets 220 are sealed with sealing caps to prevent water leakage. In addition, because the feces, leftover feed and other waste of the red porcini are denser than water, they naturally settle under the influence of gravity, slide along the inclined surface of the conical bottom towards the center of the bottom of the box, and then enter the drain outlet and be discharged through the drain pipe 3. This avoids the waste from being dispersed and deposited at the bottom of the box, and solves the problem of incomplete drainage in traditional flat-bottomed breeding boxes.

[0023] It should be added that staff can periodically open the drain valve 31 on the drain pipe 3. The drain valve 31 can be a butterfly valve or a ball valve, which is easy to open and close. After the sewage is discharged, the drain valve 31 can be closed to add a small amount of fresh water to maintain the water level, reduce the overall water change frequency, and reduce breeding costs and environmental stress.

[0024] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
