Description

Technical Field

[0001] The present invention relates to the technical field of factory farming of Babylonia areolata, and in particular to a multi-layer three-dimensional circulating water farming system for Babylonia areolata and a method for using the system. Background Art

[0002] In recent years, the Babylonia areolata farming industry has developed rapidly. However, my country's current mainstream flowing sand layer self-purification farming model has disadvantages such as low space utilization, difficulty in discharging some solid pollutants, and inconvenient manual operation. These drawbacks lead to low farming efficiency, sand layer decay, water quality deterioration, frequent diseases and other problems, which are increasingly becoming an obstacle to the green and healthy development of the Babylonia areolata farming industry.

[0003] Therefore, based on the biological characteristics of Babylonia areolata, further optimizing the breeding methods of this species, making full use of the breeding space, increasing unit yield and benefits, and reducing the incidence of diseases have become urgent problems in this field. It is necessary to provide a new Babylonia areolata breeding device to solve the above problems. Summary of the Invention

[0004] In response to the technical problems raised above, a multi-layer three-dimensional circulating water aquaculture system for Babylonia areolata and a method of use are provided, aiming to improve the utilization rate of aquaculture space, optimize sewage discharge efficiency, reduce the occurrence of diseases, and simplify the manual operation process.

[0005] The technical means adopted in the present invention are as follows: A multi-layer three-dimensional circulating aquaculture system for Babylonia areolata comprises a breeding box group, a system support, a circulating aquaculture system, a water distribution pipe, a breeding basket and a gauze. The breeding box group is arranged on the system support, one end of the breeding box group is connected to the output end of the circulating aquaculture system via a water inlet pipe, and the other end of the breeding box group is connected to the input end of the circulating aquaculture system via a return pipe. A breeding basket is provided inside each breeding box, and a gauze is provided in the breeding basket. The cultured Babylonia areolata and substrate are placed on the gauze. The water distribution pipe is connected to the water inlet pipe and is arranged below the breeding basket.

[0006] Furthermore, the circulating aquaculture system includes a sedimentation tank, a biological purification tank, an ultraviolet sterilization tank and an aeration tank connected in sequence, the sedimentation tank is connected to a return pipe, and the aeration tank is connected to a return pipe.

[0007] Furthermore, water outlet holes opening downward are provided on the water distribution pipe at preset intervals.

[0008] Furthermore, the input end of the return pipe is connected to the overflow pipe, the overflow pipe is vertically arranged inside the breeding box, and the opening of the overflow pipe is arranged at the top thereof.

[0009] Furthermore, a track is provided on the system bracket, and a roller capable of moving on the track is provided at the bottom of the breeding box.

[0010] Furthermore, the gauze is 80-120 meshes.

[0011] Furthermore, the water distribution pipe is made of PVC, and the water inlet pipe and the water return pipe are flexible rubber hoses.

[0012] Furthermore, the circulating aquaculture system is also connected to a water reservoir.

[0013] The present invention also discloses a method for using the multi-layer three-dimensional circulating aquaculture system for Babylonia areolata, comprising the following steps: Assemble the recirculating aquaculture system, with the baby snails located in the bottom sediment supported by the mesh on the culture basket; The tail water produced after the culture of Babylonia snails flows into the sedimentation tank through the overflow plate and return pipe along the upflow generated by the water distribution pipe at the bottom of the culture tank; After physical filtration, the water enters the biological purification pool through the circulation pump, and then is sterilized by UV sterilizer and oxygenated by oxygenation equipment to complete the water circulation treatment process; the treated water is then transported to the breeding box group through the water inlet pipe and water distribution pipe.

[0014] Compared with the prior art, the present invention has the following advantages: 1. Based on the characteristics of shallow-water aquaculture of Babylonia areolata, a three-dimensional aquaculture system with at least three layers is designed. At the same time, the daily maintenance and management area is transferred outside the system through a pull-out aquaculture box group, reducing the distance between layers and greatly improving the space utilization and unit output of factory-based aquaculture of Babylonia areolata.

[0015] 2. Based on the characteristics of the submerged sand culture of Babylonia areolata, the water distribution pipe is placed at the bottom of the culture box group, so that the water inlet direction is from bottom to top and eventually overflows from the top, which improves the efficiency of removing residual pollutants in the culture substrate, effectively improves the problem of substrate corruption, and reduces the incidence of diseases; at the same time, the water outlet of the water distribution pipe is ensured to face downward to avoid direct erosion of the culture substrate.

[0016] 3. Based on the characteristics of the square-spotted baby snails being cultured in the sand and being priced according to different specifications, gauze is placed on the breeding baskets in the breeding box group and the baby snails are cultured. When the baby snails are collected after they have grown, the gauze is directly removed, allowing the bottom sediment to pass through the breeding baskets and fall to the bottom of the breeding box, while the cultured baby snails are retained in the breeding baskets, which greatly facilitates the collection of the grown snails.

Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0030] like Figures 1 to 4 As shown, an embodiment of the present invention discloses a multi-layer three-dimensional circulating aquaculture system for Babylonia areolata, comprising a breeding box group 1, a system bracket 3, a circulating aquaculture system and a water distribution pipe 10, a breeding basket 13 and a gauze 14, wherein the breeding box group 1 is arranged on the system bracket 3, one end of the breeding box group 1 is connected to the output end of the circulating aquaculture system through a water inlet pipe 11, and the other end of the breeding box group is connected to the input end of the circulating aquaculture system through a return pipe 12, the breeding box group comprises several breeding boxes 2, each of which is provided with a breeding basket 13 inside, and a gauze 14 is provided in the breeding basket 13, the cultured Babylonia areolata and the bottom substrate are placed on the gauze 14, the water distribution pipe 10 is connected to the water inlet pipe 11, and the water distribution pipe 10 is arranged below the breeding basket 13.

[0031] The breeding basket 13 is a hollow structure placed in the breeding box, and the grid spacing is fixed at 0.5*0.5 cm; In this embodiment, the aquaculture tank group 1 consists of several aquaculture tanks 2 supported by a system frame 3. The recirculating aquaculture system consists of 3 to 5 layers, with each layer containing 3 to 5 aquaculture tanks. A single aquaculture tank measures 200 x 100 x 40 cm in length, width, and height. Preferably, the aquaculture tanks can be topped with an escape-prevention net.

[0032] This invention designs a three-dimensional aquaculture system with at least three layers and utilizes retractable aquaculture boxes. By reducing the spacing between layers, this system improves space utilization. It also relocates routine maintenance and management areas outside the system, facilitating operations and improving unit yield. The multi-layered structure fully utilizes vertical space, while the retractable aquaculture boxes facilitate maintenance, cleaning, and collection of baby snails. Together, these two elements create an efficient and convenient aquaculture model.

[0033] Furthermore, the recirculating aquaculture system includes a sedimentation tank 4, a biological purification tank 6, an ultraviolet sterilization tank 7, and an aeration tank 8, which are connected in sequence. The sedimentation tank 4 is connected to a return pipe 12, and the aeration tank 8 is connected to a return pipe 12. The circulating water in the aquaculture tank group 1 flows through the overflow plate and the return pipe 12 in the aquaculture tank to the sedimentation tank 4. The bottom of the aquaculture tank is tilted toward the center to form a sewage outlet. Some waste particles are collected at the bottom of the sedimentation tank 4 and then discharged through the sedimentation tank drain pipe 18. The remaining polluted particles are collected and discharged through the microfilter 5. The microfilter 5 is located in the sedimentation tank. After being filtered by the microfilter 5, the water enters the biological purification tank 6 through a circulation pump 9; the circulation pump 9 is set in the water tank where the output end of the microfilter 5 is located.

[0034] Furthermore, the water distribution pipe 10 is provided with water outlet holes with a preset interval, which are opened downward. In this embodiment, the water distribution pipe 10 is a U-shaped pipe, which is arranged at the bottom of the breeding box group 1. The breeding box 2 is made of high-quality PP sheet material, the system bracket 3 is a galvanized steel pipe, and the breeding basket 13 is made of fiberglass reinforced plastic (FRP). The water distribution pipe 10 is made of PVC, and the water inlet pipe 11 and the return pipe 12 are flexible rubber hoses with a certain margin so that the water inlet pipe 11 and the return pipe 12 can be continuously connected after the breeding box slides out of the slide rail. The daily maintenance and management area is transferred to the outside of the system by the retractable breeding box group 1, which reduces the distance between layers and greatly improves the space utilization and unit output of the factory breeding of Babylonia square-headed snails. Each breeding box has an independent water inlet pipe 11 and return pipe 12 to ensure differentiated breeding of different breeding boxes.

[0035] The present invention places the water distribution pipe at the bottom of the breeding box group, and makes the water inlet direction from bottom to top and eventually overflow from the top. Based on the characteristics of the submerged sand breeding of Babylonia areolata, it can improve the efficiency of removing residual pollutants in the breeding substrate, effectively improve the problem of substrate corruption, and reduce the incidence of diseases. At the same time, the water outlet of the water distribution pipe is ensured to be downward to avoid direct scouring of the breeding substrate, thereby protecting the living environment of Babylonia areolata. The special arrangement of the water distribution pipe and the design of the water flow direction work together to optimize the water quality conditions and the breeding environment, and improve the health and stability of the breeding.

[0036] Furthermore, the input end of the return pipe 12 is connected to the overflow pipe 16, and the overflow pipe 16 is vertically arranged inside the breeding box 2 and outside the breeding basket. The opening of the overflow pipe 16 is set at its top, a preset distance above the bottom of the breeding box.

[0037] Furthermore, a track is provided on the system support 3, and a roller 17 capable of moving on the track is provided at the bottom of the breeding box 2. The breeding box 2 is extracted from the system support through the track and the roller.

[0038] Furthermore, the gauze 14 is 80-120 mesh. The breeding basket 13 is placed in the breeding box, the gauze 14 is laid on the breeding basket 13, and the cultured baby snails and substrate (natural sand, fine ceramsite, etc.) are placed on the gauze 14; as a preferred method, the gauze 14 used is 80 mesh.

[0039] The present invention arranges a breeding basket in a breeding box, and places a gauze on the breeding basket to breed baby wind snails. When collecting the baby wind snails after they have grown, the gauze is directly removed, and the substrate passes through the breeding basket and falls to the bottom of the breeding box, while the cultured baby wind snails are retained in the breeding basket, which greatly facilitates the collection of the grown snails. The combination of the breeding basket and the gauze not only provides a suitable growth environment for the baby wind snails, but also simplifies the collection process and improves work efficiency. The two cooperate with other parts of the entire breeding system to achieve integrated breeding and collection, reducing the operation links and the stress response of the baby wind snails.

[0040] Furthermore, the circulating aquaculture system is also connected to a water reservoir 15 for water replenishment to ensure normal operation of the system.

[0041] This invention significantly increases the yield of Babylonia areolata per unit area through the multi-layer, three-dimensional arrangement of pull-out culture boxes. Water is introduced from the bottom of the culture box, optimizing water conditions and improving water purification efficiency compared to traditional water intake methods for Babylonia areolata, thereby reducing the incidence of disease. Furthermore, the addition of culture baskets to the culture box greatly facilitates the collection of Babylonia areolata after rearing.

[0042] As other optional implementation methods, water quality monitoring and automatic control functions can be configured in the circulating water system, and water quality monitoring equipment can be added, which may specifically include pH sensors, dissolved oxygen sensors, ammonia nitrogen and nitrite sensors, etc., and cooperate with the automatic control system to automatically adjust the circulating water treatment process according to the monitoring data. Specifically, the start and stop of the oxygenation equipment, adjustment of the water flow rate and other functions can be automatically controlled to achieve more accurate water quality management and improve the stability and reliability of aquaculture.

[0043] The present invention also discloses a method for using the multi-layer three-dimensional circulating aquaculture system for Babylonia areolata, comprising the following steps: Assemble the recirculating aquaculture system, with the baby snails located in the bottom sediment supported by the mesh on the culture basket; The tail water produced after the culture of Babylonia snails flows into the sedimentation tank through the overflow plate and return pipe along the upflow generated by the water distribution pipe at the bottom of the culture tank; After physical filtration, the water enters the biological purification pool through the circulation pump to remove harmful substances such as ammonia nitrogen and nitrite. It is then sterilized by UV sterilizer lamps and oxygenated by oxygenation equipment to complete the water circulation treatment process. The treated water is then transported to the breeding box group through the water inlet pipe and water distribution pipe.

[0044] After the above device was built, the actual effect of the system in cultivating Babylonia areolata was verified: Select the same batch of Babylonia areolata with uniform individual size, and use 1000 pieces / m 2 The density of the culture medium was put into the device of the present invention (experimental group) and the traditional flow-through culture pond (control group). The culture period was 3 months. During this period, the salinity was in the range of 32-35‰, the dissolved oxygen content was greater than 5 mg / L, the pH was 6.5-7.0, the ammonia nitrogen content was less than 0.8 mg / L, and the nitrite nitrogen content was less than 0.02 mg / L. During the culture period, the snails were fed with fresh ice-cold blue trevally (Decapterus maruadsi) at a weight equivalent to 5% of their body weight. The snails were weighed every 15 days to update the feeding amount. The feeding frequency was 2-3 days of continuous feeding followed by 1 day of fasting. The feeding time was 7:00 PM to 8:00 PM daily. Fish bones were cleaned and the bottom sand was rinsed regularly. After 3 months of culture, the growth and nutritional performance of the Babylonia areolata in the experimental group and the control group were compared as shown in the following table:

[0045] The average body weight, shell height, shell width and feed conversion efficiency of the experimental group were significantly increased compared with the control group.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
