Description

Technical Field

[0001] This invention relates to the field of shrimp farming technology, and in particular to a circular integrated intelligent farming system and farming method for Litopenaeus vannamei. Background Technology

[0002] Existing Pacific white shrimp farming systems feed shrimp larvae in the rearing ponds until harvest, neglecting the different feeding needs of shrimp during the juvenile and adult stages. These systems primarily rely on water changes to address declining water quality, which is not only wasteful of resources but also time-consuming and labor-intensive. Furthermore, the presence of a certain number of diseased shrimp in existing farming methods can easily affect the entire shrimp population, thus threatening shrimp farming. Summary of the Invention

[0003] To address the aforementioned problems in the existing technology, this invention aims to provide a circular integrated intelligent aquaculture system and method for Litopenaeus vannamei, which solves the problems of neglecting the different feeding needs of shrimp during the juvenile and adult stages, wasting water resources, and threatening shrimp farming due to the inability to remove diseased shrimp in existing Litopenaeus vannamei aquaculture systems.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0005] A recirculating intelligent aquaculture system for Litopenaeus vannamei is provided, which includes an aquaculture module and a bottom water circulation module. The aquaculture module includes a shrimp larvae rearing pond and a mature shrimp rearing pond, which are connected by pipes and valves.

[0006] The top of the shrimp fry rearing pond and the mature shrimp farming pond are equipped with multiple holding tanks, each with a green bottom plate.

[0007] The bottom water circulation module includes a circulation pump, and a sewage pipe is installed on one side of the circulation pump. The sewage pipe is connected to the bottom of the aquaculture module, including the shrimp fry rearing pond and the mature shrimp rearing pond.

[0008] A filter unit is installed on the other side of the circulation pump, and a circulation pipeline is installed on the other side of the filter unit. Two branch pipes are installed at the free end of the circulation pipeline. The circulation pipeline is connected to the top of the aquaculture module, including the shrimp fry rearing pond and the mature shrimp rearing pond, through the two branch pipes respectively.

[0009] Furthermore, the integrated intelligent aquaculture system for Litopenaeus vannamei also includes multiple feeding modules, which are respectively set on top of the shrimp larvae rearing pond and the mature shrimp farming pond. Each feeding module includes a hopper, and a feeding cycle regulating valve is installed at the outlet at the bottom of the hopper. The feeding cycle regulating valve is used to periodically open or close the outlet at the bottom of the hopper.

[0010] The hopper at the top of the shrimp larvae rearing pond is filled with a mixture of juvenile shrimp feed, while the hopper at the top of the mature shrimp farming pond is filled with a mixture of mature shrimp feed.

[0011] Furthermore, the feeding cycle regulating valve device includes a valve plate located at the outlet at the bottom of the hopper. The valve plate is rotatably connected to the outlet at the bottom of the hopper via a rotating shaft. A rotating motor is fixedly connected to the rotating shaft on the outer wall of the hopper. A PLC controller is installed on the rotating motor. The PLC controller integrates a timing module. The PLC controller periodically controls the rotating motor to drive the rotating shaft and valve plate to rotate through the timing module.

[0012] Furthermore, the integrated intelligent aquaculture system for Litopenaeus vannamei also includes a temperature control module, which includes an insulated shed that covers the shrimp larvae rearing pond and the mature shrimp rearing pond. The insulated shed is equipped with a heating unit and a temperature sensor. The heating unit adjusts its own heating temperature based on the temperature information collected by the temperature sensor inside the insulated shed. Multiple feeding modules are fixedly connected to the top of the insulated shed.

[0013] Furthermore, the heating unit includes a combustion furnace installed inside an insulated shed, a combustion stove installed inside the combustion furnace, an air inlet pipe installed inside the combustion stove, and an electromagnetic air volume control valve installed on the air inlet pipe.

[0014] A control module electrically connected to a temperature sensor is installed on the outside of the combustion furnace. The control module uses the temperature sensor to collect temperature information inside the insulation shed and controls the opening and closing of the electromagnetic gas volume control valve.

[0015] Furthermore, the integrated intelligent aquaculture system for Litopenaeus vannamei also includes a biogas module, which is connected to the filtration unit through a recycling module. The recycling module is used to collect uneaten feed and shrimp excrement.

[0016] The biogas module includes a biogas digester. The bottom of the biogas digester is connected to the recovery module through a pipe, and the top of the biogas digester is connected to the air inlet pipe through a gas supply pipe.

[0017] Furthermore, the integrated intelligent aquaculture system for Litopenaeus vannamei also includes an oxygenation module, which comprises multiple oxygen content detection units and aeration units. These units are respectively located in shrimp larvae rearing ponds and mature shrimp rearing ponds; each oxygen content detection unit is an oxygen content sensor.

[0018] Furthermore, the integrated intelligent aquaculture system for Litopenaeus vannamei also includes a water quality regulation module, which comprises a pH detection unit and a pH regulation unit.

[0019] This invention also provides a method for cultivating a recirculating intelligent aquaculture system for Litopenaeus vannamei, comprising:

[0020] Step 1, Pond Treatment: Clean the silt from the shrimp larvae rearing pond and mature shrimp rearing pond, then disinfect with quicklime, and rinse with clean water. The edges of the shrimp larvae rearing pond and mature shrimp rearing pond need to be cut and processed to enlarge the pond opening. Then, multiple continuous V-shaped containment troughs are processed downwards in the enlarged part. Finally, a green bottom plate is laid in the containment trough to create a color difference with the shrimp. Taking advantage of the fact that diseased and weak shrimp move along the edge and have poor activity, they will find it difficult to leave after entering, stay away from the normal shrimp group, and increase the risk of exposure to birds. This is used to remove diseased and weak shrimp.

[0021] Step 2, introducing seawater: lay mud and sand on the bottom of the shrimp larvae rearing pond and the mature shrimp farming pond, then introduce seawater into the shrimp larvae rearing pond and the mature shrimp farming pond, and carry out water purification treatment, including disinfection and transparency adjustment. After completion, the water is allowed to sit and dry.

[0022] Step 3, water quality control: During the stabilization process, the pH value of the pool water needs to be measured and adjusted to 7.3-8.6 before introducing algae;

[0023] Step 4, shrimp larvae release: Select juvenile white shrimp from Pacific white shrimp and release them into the shrimp larvae rearing pond;

[0024] Step 5, Feeding and Rearing: A mixture of Litopenaeus vannamei feed and zooplankton nauplius is introduced into the shrimp larvae rearing pond via the feeding module. This mixture contains 40% protein. Once the larvae reach 5cm in length, they are transferred to the mature shrimp rearing pond. The feeding module then introduces a mixture of Litopenaeus vannamei feed, aquatic insects, and small mollusks into the mature shrimp rearing pond. This mixture contains 35% protein.

[0025] Step Six, Rotational Harvesting of Shrimp: After two months of cultivation, rotational harvesting of shrimp is carried out. Shrimp guide nets with mesh sizes that match the adult shrimp size are used to catch the mature shrimp.

[0026] The beneficial effects of this invention are as follows:

[0027] Compared to existing Pacific white shrimp farming systems, this invention features a unique farming module that separates juvenile and mature shrimp for feeding, providing different feeding environments and feeds to improve the overall quality of the shrimp. The bottom-level water circulation module collects uneaten feed and shrimp excrement, which are then processed by a biogas module to generate biogas for the heating unit. This heating unit maintains the temperature of the shrimp farming environment close to the optimal temperature for shrimp growth, facilitating faster growth. The combination of the bottom-level water circulation module, biogas module, and heating unit not only slows down water quality degradation but also saves energy and resources. Furthermore, this invention utilizes a method of creating containment troughs around the farming pond and laying green bottom plates within them. The green bottom plates create a color contrast with the shrimp, and by exploiting the fact that diseased and weak shrimp tend to move along the edges and have lower activity levels, they are difficult to remove once inside the containment troughs, thus keeping them away from the normal shrimp population and increasing their risk of exposure to birds. This method effectively solves the problem of diseased and weak shrimp easily infecting the shrimp population when mixed in. Attached Figure Description

[0035] The specific embodiments of the present invention are described below to enable those skilled in the art to understand the present invention. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they are within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.

[0036] like Figures 1-2 As shown, the present invention provides a circular integrated intelligent aquaculture system for Litopenaeus vannamei, which includes an aquaculture module 1 and a bottom water circulation module 2. The aquaculture module 1 includes a shrimp larvae rearing pond 101 and a mature shrimp rearing pond 102, which are connected by pipes and valves.

[0037] By setting up shrimp larvae rearing pond 101 and mature shrimp rearing pond 102 in the aquaculture module 1, juvenile shrimp and mature shrimp are fed separately, providing different feeding environments and feeds during the shrimp farming period, which meets the different feeding needs of shrimp in the juvenile and adult stages, thereby improving the overall quality of shrimp; after the shrimp larvae are raised, the pipeline valve can be opened directly to transfer the shrimp larvae to the mature shrimp rearing pond 102 for rearing.

[0038] like Figure 3 As shown, multiple containment troughs 3 are continuously arranged around the top of the shrimp larvae rearing pond 101 and the mature shrimp farming pond 102. Each containment trough 3 is lined with a green bottom plate 4. Specifically, the containment troughs 3 are V-shaped. The arrangement of multiple containment troughs 3 can take advantage of the fact that diseased and weak shrimp move along the edge and have poor activity, making it difficult for them to leave after entering the containment troughs 3 and stay away from the normal shrimp population. At the same time, the green bottom plate 4 creates a color difference with the shrimp, increasing the risk of exposure to birds. This achieves the purpose of removing diseased and weak shrimp and reducing the risk of shrimp farming.

[0039] The bottom water circulation module 2 includes a circulation pump 201, and a sewage pipe 202 is provided on one side of the circulation pump 201. The sewage pipe 202 is connected to the bottom of the aquaculture module 1, which includes a shrimp fry rearing pond 101 and a mature shrimp rearing pond 102.

[0040] A filter unit 203 is provided on the other side of the circulation pump 201, and a circulation pipe 204 is provided on the other side of the filter unit 203. Two branch pipes are provided at the free end of the circulation pipe 204. The circulation pipe 204 is connected to the top of the aquaculture module 1, including the shrimp fry rearing pond 101 and the mature shrimp rearing pond 102, through the two branch pipes respectively.

[0041] The circulating pump 201 discharges excrement and uneaten feed from the shrimp larvae rearing pond 101 and the mature shrimp rearing pond 102 via the drain pipe 202, thus purifying the pond water. The excrement and uneaten feed in the drain pipe 202 are then filtered by the filter unit 203, which can be a filter screen with a mesh size set according to actual conditions. The filtered water is then circulated back to the shrimp larvae rearing pond 101 and the mature shrimp rearing pond 102 through the circulating pipe, achieving the goal of saving water resources.

[0042] like Figure 2 and Figure 4 As shown, preferably, the integrated intelligent aquaculture system for Pacific white shrimp also includes multiple feeding modules 5, which are respectively set on the top of the shrimp larvae rearing pond 101 and the mature shrimp rearing pond 102. Each feeding module 5 includes a hopper 501, and a feeding cycle regulating valve device 502 is provided at the outlet at the bottom of the hopper 501. The feeding cycle regulating valve device 502 is used to periodically open or close the outlet at the bottom of the hopper 501.

[0043] The hopper 501 located at the top of the shrimp larvae rearing pond 101 is filled with juvenile shrimp mixed feed, and the hopper 501 located at the top of the mature shrimp farming pond 102 is filled with mature shrimp mixed feed.

[0044] The feeding cycle regulating valve device 502 includes a valve plate 5021 located at the outlet at the bottom of the hopper 501. The valve plate 5021 is rotatably connected to the bottom outlet of the hopper 501 via a rotating shaft 5022. A rotating motor 5023 is fixedly connected to the rotating shaft 5022 on the outer wall of the hopper 501. A PLC controller is installed on the rotating motor 5023. The PLC controller integrates a timing module. The PLC controller periodically controls the rotating motor 5023 to drive the rotating shaft 5022 and the valve plate 5021 to rotate through the timing module.

[0045] By adjusting the feeding cycle valve device 502, the valve plate 5021 is periodically opened or closed, thereby enabling the hopper 501 to periodically feed the shrimp larvae rearing pond 101 and the mature shrimp farming pond 102. The opening and closing cycle of the valve plate 5021 can be realized by a PLC controller and a timing module, thus achieving automated shrimp farming.

[0046] like Figure 5 As shown, the integrated intelligent aquaculture system for Litopenaeus vannamei also includes a constant temperature module 6, which includes a heat preservation shed 601. The heat preservation shed 601 covers the shrimp larvae rearing pond 101 and the mature shrimp rearing pond 102. Specifically, the heat preservation shed 601 is a plastic film frame structure. The heat preservation shed 601 has doors and windows to facilitate the entry and exit of people and birds, so as to remove diseased and weak shrimp in the shrimp larvae rearing pond 101 and the mature shrimp rearing pond 102.

[0047] The insulated shed 601 is equipped with a heating unit 602 and a temperature sensor 603. The heating unit 602 adjusts its own heating temperature based on the temperature information collected by the temperature sensor 603 inside the insulated shed 601. Multiple feeding modules 5 are fixedly connected to the top of the insulated shed 601. The constant temperature module 6 keeps the temperature of the shrimp farming environment close to the temperature suitable for shrimp growth, which helps to improve the growth rate of shrimp.

[0048] Specifically, the heating unit 602 includes a combustion furnace 6021 installed inside the insulation shed 601, a combustion stove 6022 installed inside the combustion furnace 6021, an air inlet pipe 6023 installed inside the combustion stove 6022, and an electromagnetic gas flow control valve 6024 installed on the air inlet pipe 6023. A control module electrically connected to a temperature sensor 603 is installed outside the combustion furnace 6021. The control module collects temperature information inside the insulation shed 601 through the temperature sensor 603 to control the opening and closing degree of the electromagnetic gas flow control valve 6024. The gas source for the heating unit 602 can be natural gas, biogas, or bottled coal gas, etc.

[0049] Preferably, but not limited to, in this embodiment, the gas source of the heating unit 602 is biogas; the Litopenaeus vannamei circular integrated intelligent aquaculture system also includes a biogas module 8, which is connected to the filter unit 203 through a recovery module 7, which is used to collect uneaten feed and shrimp excrement; the biogas module 8 includes a biogas fermenter 801, the bottom of which is connected to the recovery module 7 through a pipe, and the top of which is connected to the air inlet pipe 6023 through a gas supply pipe.

[0050] By collecting uneaten feed and shrimp excrement, the uneaten feed and shrimp excrement are processed by the biogas module 8 to generate biogas for the heating unit 602, thus achieving the effect of saving energy.

[0051] Specifically, the integrated intelligent aquaculture system for Litopenaeus vannamei also includes an oxygenation module 9, which includes multiple oxygen content detection units 901 and aeration units. The multiple oxygen content detection units 901 and aeration units are respectively set in the shrimp larvae rearing pond 101 and the mature shrimp rearing pond 102; each oxygen content detection unit 901 is an oxygen content sensor.

[0052] Specifically, the integrated intelligent aquaculture system for Litopenaeus vannamei also includes a water quality regulation module 10, which includes a pH detection unit and a pH regulation unit.

[0053] like Figure 6 As shown, the present invention also provides a method for aquaculture using a recirculating integrated intelligent aquaculture system for Litopenaeus vannamei, comprising:

[0054] Step 1, Treatment of the breeding ponds: Clean the silt in the shrimp larvae rearing pond 101 and the mature shrimp rearing pond 102, then disinfect with quicklime, and rinse with clean water. The shrimp larvae rearing pond 101 and the mature shrimp rearing pond 102 need to be cut and processed along the edges to enlarge the pond opening. Then, multiple continuous V-shaped receiving troughs 3 are processed downwards in the enlarged part. Finally, a green bottom plate 4 is laid in the receiving trough 3 to create a color difference with the shrimp. Taking advantage of the fact that diseased and weak shrimp move along the edge and have poor activity, they will find it difficult to leave after entering, stay away from the normal shrimp group, and increase the risk of exposure to birds. This is used to remove diseased and weak shrimp.

[0055] Step 2, introduce seawater: lay mud and sand on the bottom of shrimp larvae rearing pond 101 and mature shrimp rearing pond 102, then introduce seawater into shrimp larvae rearing pond 101 and mature shrimp rearing pond 102, and carry out water purification treatment, including disinfection and transparency adjustment. After completion, the water is allowed to dry in the sun.

[0056] Step 3, water quality control: During the stabilization process, the pH value of the pool water needs to be measured and adjusted to 7.3-8.6 before introducing algae;

[0057] Step 4, shrimp larvae release: Select juvenile white shrimp and release them into shrimp larvae rearing pond 101;

[0058] Step 5, Feeding and Rearing: Through the feeding module 5, a mixture of special feed for Litopenaeus vannamei and zooplankton nauplius is added to the shrimp larvae rearing pond 101. The protein content of this mixture is 40%. After the juvenile shrimp grow to 5cm, they are transferred to the mature shrimp rearing pond 102. The feeding module 5 then adds a mixture of special feed for Litopenaeus vannamei, aquatic insects, and small mollusks to the mature shrimp rearing pond 102. The protein content of this mixture is 35%.

[0059] Step Six, Rotational Harvesting of Shrimp: After two months of cultivation, rotational harvesting of shrimp is carried out. Shrimp guide nets with mesh sizes that match the adult shrimp size are used to catch the mature shrimp.

[0060] In summary, compared to existing Pacific white shrimp farming systems, the present invention's designed farming module 1 separates juvenile and mature shrimp for feeding, providing different feeding environments and feeds, thereby improving the overall quality of the shrimp. The bottom-level water circulation module 2 of this invention collects uneaten feed and shrimp excrement, which, after being processed by the biogas module 8, generates biogas for the heating unit 602. The heating unit 602 maintains the temperature of the shrimp farming environment close to the optimal temperature for shrimp growth, facilitating faster shrimp growth. The bottom-level water circulation module 2 and the biogas module... The installation of module 8 and heating unit 602 not only slows down the decline in water quality but also saves energy and resources. This invention, by processing a containment tank 3 around the aquaculture pond and laying a green bottom plate 4 inside the containment tank 3, creates a color difference between the green bottom plate 4 and the shrimp. At the same time, it utilizes the principle that diseased and weak shrimp move along the edge and have poor activity, making it difficult for them to leave after entering the containment tank 3, thus keeping them away from the normal shrimp population and increasing their risk of exposure to birds. This method of removing diseased and weak shrimp effectively solves the problem of diseased and weak shrimp easily infecting the shrimp population when mixed in.
