Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, specifically to an integrated aquaculture model based on the co-cultivation of agricultural planting and aquaculture. Background Technology

[0002] Fish-shrimp polyculture is an ecological polyculture model that combines fish farming with shrimp farming (usually Litopenaeus vannamei, also known as whiteleg shrimp) as the main farming method. This model significantly improves aquaculture success rates and economic benefits, promotes increased production and income for fishermen, fosters green, healthy, and high-quality development of the aquaculture industry, and ensures the quality and safety of aquatic products and food.

[0003] In mixed aquaculture and crop farming, animal excrement provides abundant nutrients for crop growth, while the water purified and absorbed by the crops can be returned to the aquaculture system. This harmonious symbiosis between species creates a mutually beneficial ecological relationship, representing a sustainable, cyclical, and low-carbon production model. To explore better farming models and ensure increased income from multiple sources, new integrated farming approaches need to be developed. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the present invention provides an integrated aquaculture model based on the co-cultivation of agricultural planting and aquaculture.

[0005] To achieve the above objectives, the present invention provides an integrated aquaculture pond for combined agricultural planting and aquaculture, wherein: the aquaculture pond includes a first aquatic animal breeding area, a second aquatic animal breeding area, and a planting area; the first aquatic animal breeding area is used for raising fish, the second aquatic animal breeding area is used for raising shrimp and crabs, and the planting area is used for planting crops; the planting area is located between the first aquatic animal breeding area and the second aquatic animal breeding area, and a net is installed on the side closer to the first aquatic animal breeding area; when the first aquatic animal breeding area and the second aquatic animal breeding area... When the water bodies in the animal breeding areas are connected, the water levels in the first and second aquatic animal breeding areas are at the same height. Water transfer equipment is installed in the first and / or second aquatic animal breeding areas to transfer and oxygenate the water. The barrier net is divided into an upper barrier net, a lower baffle, and a supporting plate. Water flows through the upper barrier net, and the netting of the upper barrier net is set below the top to prevent shrimp and crabs from crawling out. The lower baffle intercepts suspended solids and organic matter with high content in the lower water. The supporting plate is set on one side of the lower baffle and connected to the collection device.

[0006] Preferably, the barrier net is used to prevent fish from passing through.

[0007] Preferably, the water transfer equipment includes an aerator or a waterwheel.

[0009] Preferably, the water depth of the first aquatic animal breeding area is greater than that of the second aquatic animal breeding area.

[0010] Preferably, the water depth ratio between the first aquatic animal breeding area and the second aquatic animal breeding area is (2-5):(1-3).

[0011] This invention provides an integrated aquaculture method for combining agricultural planting and aquaculture in the aforementioned ponds. The integrated aquaculture involves selecting the start time for each of the three aquatic animal breeding areas (first, second, and planting areas) and periodically operating the supporting plate to promote crop growth in the planting area, thereby increasing the yield and income of fish, shrimp, crabs, and crops.

[0012] The beneficial effects of this invention are as follows:

[0013] The aquaculture ponds used in this application are designed with varying depths and areas to meet different water resource needs. This allows for the survival of fish and shrimp / crab within a limited area. Although the area allocated to each aquaculture species is reduced, the overall yield is increased. The residual fertilizer produced by aquaculture can be used in crop cultivation, thus increasing the production and income of fish, shrimp / crab, and crops. Attached Figure Description

[0018] To better illustrate the purpose, technical solution, and advantages of this invention, the following will provide further explanation of this application in conjunction with specific embodiments.

[0019] Example 1

[0020] This embodiment provides an integrated aquaculture model based on the combined operation of agricultural planting and aquaculture to improve the overall effect of aquaculture and agricultural planting. This application achieves this through integrated aquaculture in specific aquaculture ponds, such as... Figure 1-2 The details are as follows:

[0021] The aquaculture pond comprises a first aquatic animal breeding area 100, a second aquatic animal breeding area 200, and a planting area 300. The first aquatic animal breeding area 100 is used for fish farming, the second aquatic animal breeding area 200 is used for shrimp and crab farming, and the planting area 300 is used for crop cultivation. The planting area 300 is located 200 meters between the first and second aquatic animal breeding areas, with a net 400 installed on the side closest to the first aquatic animal breeding area 100. When the water bodies of the first and second aquatic animal breeding areas 100 and 200 are connected, the water levels in both areas are the same. Water transfer equipment 500 is installed within the first and / or second aquatic animal breeding areas 100 for water transfer and aeration. This water transfer equipment includes aerators, waterwheels, or water pumps. The bottom of the first aquatic animal breeding area 100 is deeper than that of the second aquatic animal breeding area 200, meeting the water volume requirements of fish. Preferably, the area ratio of the first aquatic animal breeding area 100, the second aquatic animal breeding area 200, and the planting area 300 is (15-45):(50-75):(5-10), and the water depth ratio of the first aquatic animal breeding area 100 to the second aquatic animal breeding area 100 is (2-5):(1-3). When the water bodies of the first aquatic animal breeding area 100 and the second aquatic animal breeding area 200 are connected, the topsoil layer of the planting area 300 is below the water surface.

[0022] A vertical barrier net 400 is installed on one side of the planting area 300. It consists of an upper barrier net 401, a lower baffle 402, and a supporting plate 403. Water flows between the first aquatic animal breeding area 100 and the second aquatic animal breeding area 200 through the upper barrier net 401. The netting of the upper barrier net 401 is positioned below the top to intercept fish and prevent shrimp and crabs from climbing out using the netting. The lower baffle 402 intercepts suspended solids and organic matter with high concentrations in the lower water layer. A collection device 600 is installed within the planting area 300. The supporting plate 403 is located on one side of the lower baffle 402, providing support and coordination. The supporting plate 403 is connected to the collection device 600, which is used to collect sediment accumulated at the bottom of the planting area 300.

[0023] Integrated aquaculture involves selecting the start time for aquaculture in the first aquatic animal breeding area 100, the second aquatic animal breeding area 200, and the planting area 300, respectively, and periodically operating in conjunction with plate 403 to promote crop growth in the planting area, thereby increasing the production and income of fish, shrimp, crabs and crops.

[0024] Example 2

[0025] This embodiment provides an integrated aquaculture model based on the co-cultivation of agricultural planting and aquaculture. Unlike the above embodiments, the collecting device 600 is used in the gaps between crops in the planting area 300 to ensure that the moving plate does not affect the planted crops.

[0026] Specifically, such as Figure 3 The collection device 600 includes a track 601, a roller 602 mounted on the track, and a collection plate 603. One end of the collection plate 603 is connected to the roller 602, while the other end is free. The flat or rolled-up state of the collection plate 603 can be adjusted by changing the rotation direction of the roller 602. When the roller 602 is moved along the track 601, the placement position of the collection plate 603 can be changed. Preferably, the collection plate 603 is placed in the gap between crop cultivation in the planting area 300, at which point the collection plate 603 is in a flat state. After a period of time, rotating the roller 602 slowly rolls up the collection plate 603, thus collecting the sediment. Preferably, the track 601 is fixed to the bottom of one side of the planting area 300 by a base or support rod, and a mating plate 403 is connected to the base or support rod of the track 601. The middle part of the roller 602 is fitted onto the track 601. When an external force is applied to the roller 602, it rotates around the passage 601, thereby achieving the winding of the collection plate 603. Then, the roller 602 is moved to remove the sediment accumulated in the area.

[0027] Furthermore, one end of track 601 extends into the first aquatic animal breeding area 100, allowing the wound roller 602 to be directly moved into the first aquatic animal breeding area 100. Reversing the roller 602 unfolds the collection plate 603, dispersing the wound sediment into the first aquatic animal breeding area 100, enabling the sediment to be reused, such as improving the water quality of the first aquatic animal breeding area 100 or being consumed. To better achieve sediment dispersion, track 601 is separated between the tracks in the first aquatic animal breeding area 100 and the planting area 300, forming the first track 6011 and the second track 6012 respectively. Preferably, the shaft diameters of the first track 6011 and the second track 6012 are the same, ensuring that the roller 602 can be stably mounted. After the roller 602 is wound up, it is removed from the second track 6012 and placed onto the first track 6011. After the collecting plate 603 is unwound, the roller 602 is connected to the vibrating device 700. The vibrating device 700 is turned on, and the frequency is controlled to quickly disperse the sediment on the collecting plate 603 into the water. The vibrating device can be a vibrator or a rotating machine. In use, the roller 602 can also be directly connected to the vibrating device 700, and the collecting plate 603 can be unfolded and vibrated after the vibrating device 700 is turned on. Preferably, the track 601 is also provided with a third track 6013. The third track 6013 is arranged parallel to the second track 6012, and the ends of the two are connected away from the first track 6011. The roller 602 and collecting plate 603 taken out from the first aquatic animal breeding area 100 can be placed on the third track 6013, moved to an appropriate position, and continued to be used, without affecting the unwound roller 602 and collecting plate 603 in the planting area 300. Preferably, the height of the end of the third track 6013 closest to the first aquatic animal breeding area 100 is greater than the height of the other end, which facilitates the positioning of rollers 602, etc. Preferably, multiple rollers 602 can be set up, and the collecting plates 300 are spread out in the gaps between crops in the planting area 300.

[0028] Better, such as Figure 4The collecting sheet 300 is made of a retractable material, consisting of an upper mesh sheet 301 and a bottom stainless steel plate or other material plate 302. The two can collect and hold sediment. In an aquatic environment, the plate provides greater stability, and the mesh can adhere to the sediment, maintaining a stable bottom environment in the planting area 300. Preferably, the mesh sheet 301 is movably connected to the plate 302, such as through a collar. For easy retraction, the plate 302 is relatively thin, and has a free end during sediment collection, resulting in a slight curvature. Once the crops in the planting area 300 are mature, the mesh sheet 301 can be removed, and the other end of the plate 302 can be connected to a tractor or other mobile device. The roller 602 moves synchronously with the mobile device towards the first aquaculture area 100 or the second aquaculture area 200. At this point, the curvature of the plate 302 is flattened, allowing for crop harvesting or bottom tillage, preparing for subsequent planting.

[0029] Although the area allocated to each cultured species in the aquaculture ponds used in this application is reduced, the overall yield is increased. This is because fish, with their gregarious lifestyle, live in groups in the water, requiring a smaller water volume and thus a smaller area. However, shrimp and crabs, which are more dispersed, require a larger water surface area for growth. Therefore, by designing the depth and area of ​​the ponds to meet the different needs of water resource utilization, the survival of fish and shrimp / crabs can be satisfied within the limited aquaculture ponds.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
