Description

Technical Field

[0001] The invention relates to a shrimp circulating water culture method and system, belonging to the technical field of shrimp culture. Background Art

[0002] Macrobrachium rosenbergii is favored by farmers because of its delicious meat and strong market demand. However, due to its strong aggressiveness, it has been difficult to increase the stocking density in recirculating aquaculture. This is mainly due to the fact that Macrobrachium rosenbergii has a life habit of periodic molting. During the molting period, the shrimp is fragile and less active, making it very easy to be cannibalized by its own kind. As a result, the stocking density in the recirculating water system cannot be effectively increased, which has become an important problem in the recirculating aquaculture of Macrobrachium rosenbergii. Traditional feeding methods often make it difficult to accurately control the amount of feed, resulting in feed waste and water pollution. At the same time, it also affects the growth uniformity of Macrobrachium rosenbergii, resulting in inconsistent sizes, which ultimately affects the farming results. The traditional soil pond farming model consumes a lot of water and has a low utilization rate, which causes a large waste of water resources and is difficult to meet the requirements of modern efficient and water-saving farming. Since inland areas are far away from coastal shrimp production areas, it is difficult to ensure a stable supply of fresh shrimp by relying on traditional farming and transportation methods.

[0003] Therefore, the existing rosenbergii shrimp farming has the following technical problems:

[0004] 1) It is difficult to increase the breeding density: Due to the living habits of Macrobrachium rosenbergii, it is difficult to breed it at a high density in a circulating water system. This is because Macrobrachium rosenbergii generally undergoes multiple moltings when it grows from a juvenile to an adult. Molting is the weakest period of life activity. Generally, shrimps are inactive and are easily eaten by other organisms and their own kind, resulting in the inability to increase the breeding density.

[0005] 2) Inaccurate and uneven feeding amount: Under the traditional feeding method, farmers often find it difficult to accurately control the feeding amount. This uneven feeding method will cause feed waste, and will also affect the uniformity of shrimp growth, making the shrimp sizes inconsistent, reducing the overall breeding efficiency.

[0006] 3) Problems of high water consumption and low efficiency: Inland areas are far away from coastal shrimp production areas, and traditional breeding and transportation methods cannot guarantee a stable supply of fresh shrimp. The traditional soil pond breeding model consumes a lot of water and has a low utilization rate, which causes a great waste of water resources. Summary of the invention

[0007] In order to solve the above technical problems, the present invention aims to provide a high-density, high-efficiency, water-saving Macrobrachium rosenbergii farming method and system, change the shrimp farming method in inland areas, and improve production and sustainability.

[0008] The present invention adopts the following technical solutions:

[0012] Preferably, the feeding machine support frame 4 is a pair of parallel beams.

[0013] Preferably, the avoidance groove A4 is smooth and burr-free.

[0014] Preferably, the rectangular cement pool 1 has square cut corners, the water inlet pipe 8 is arranged at a pair of square cut corners of the diagonal support, a row of water inlet holes are opened on the side wall of the water inlet pipe 8, and the water inlet holes on the two water inlet pipes 8 are oriented clockwise or counterclockwise, so that the water in the pool has a tendency to rotate; the drainage system includes a drainage hole located in the center of the pool bottom.

[0015] Preferably, an anti-jumping net 9 is arranged on the top of the rectangular cement pool 1, and the anti-jumping net 9 is arranged in two pieces with the feeding machine support frame 4 as the central axis.

[0016] Preferably, the size of the rectangular cement pool 1 is 4×4m, the foundation beam 2 is an I-beam, and there are two feeding machines 5. The feeding machine 5 can slide with the feeding support frame 4 to facilitate the addition of feed.

DETAILED DESCRIPTION

[0028] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] See also Figure 1-Figure 2 A circulating water culture system for Macrobrachium rosenbergii comprises a rectangular cement pool 1, a multi-layer avoidance nest 3, a feeder 5, a water inlet pipe 8, and a drainage system; a plurality of foundation beams 2 are arranged along the X direction on the upper edge of the rectangular cement pool 1, and a feeder support frame 4 is arranged along the Y direction in the middle of the upper part of the plurality of foundation beams 2; adjacent foundation beams 2 form a supporting component for the multi-layer avoidance nest 3, and the multi-layer avoidance nest 3 is in a rectangular shape and is arranged vertically and horizontally in the rectangular cement pool 1 along the X and Y directions; the multi-layer avoidance nest 3 comprises a top cover A2, a pair of vertical plates are connected below the top cover A2, a multi-layer porous interlayer A3 is fixedly arranged in the middle of the vertical plates, and a multi-layer avoidance groove A4 is fixedly arranged on the outer side of the vertical plates; the outer edge of the top cover A2 exceeds the avoidance groove A4 when viewed from a top view, and is used to be hung on the foundation beam 2, and the top of the top cover A2 has a handle; the feeder 5 is fixed on the feeder support frame 4, and the shrimp feeding area 6 is within a certain spacing range on both sides below the feeder support.

[0030] In this embodiment, the top cover A2 can be fixed to the base beam 2 by bolts (the bolts are not shown in the drawings), or can be directly placed on the base beam 2.

[0031] In this embodiment, the avoidance groove A4 is an L-shaped plate structure with the flange facing upward. Figure 2 shown.

[0032] In this embodiment, the feeding machine support frame 4 is a pair of parallel beams in the Y direction.

[0033] In this embodiment, the avoidance groove A4 must be smooth and free of burrs, because the shrimps after molting will randomly fall to a place due to stress bouncing, and must avoid being scratched by burrs. Since the light inside the pool is relatively dim, there is a certain probability that the molting shrimps can avoid being eaten by other shrimps.

[0034] In this embodiment, see Figure 1The rectangular cement pool 1 has square cut corners, and the water inlet pipe 8 is arranged at a pair of square cut corners of the diagonal brace. A row of water inlet holes is opened on the side wall of the water inlet pipe 8. The directions of the water inlet holes on the two water inlet pipes 8 are the same clockwise or counterclockwise, so that the water in the pool has a tendency to rotate; the drainage system includes a drainage hole located at the center of the pool bottom. Because there are multiple escape nests distributed in the shrimp pond, it will cause the flow problem of the shrimp pond, so multiple high and low water inlets are provided to alleviate the water flow problem of the pool.

[0035] In this embodiment, an anti-jumping net 9 is arranged on the top of the rectangular cement pool 1. The anti-jumping net 9 is arranged in two pieces with the feeding machine support frame 4 as the central axis. The attached figure shows only a small part of the anti-jumping net. In fact, there should be two anti-jumping nets 9 covering the upper part of the rectangular cement pool 1. Because there is a feeding machine in the middle, the anti-jumping net 9 is divided into two pieces.

[0036] In this embodiment, the size of the rectangular cement pool 1 is 4×4m, the foundation beam 2 is an I-beam, and the number of feeding machines 5 is two. The feeding machine 5 can slide with the feeding support frame 4 to facilitate the addition of feed. Figure 1 shown.

[0037] In this embodiment, an underwater high-definition camera 7 is provided in the shrimp feeding area 6 .

[0038] In the above-mentioned Macrobrachium rosenbergii recirculating water culture method, the high-definition underwater camera 7 captures the picture of the shrimp feeding and transmits it to the terminal, and the terminal program identifies the shrimp feeding desire, feed residue and shrimp size in real time;

[0039] If the camera 7 identifies that the shrimps have a strong desire to eat, the terminal will control the feeding machine to feed until the shrimps are full. If the camera 7 identifies that there are some shrimps of large sizes, then trapping should be adopted to isolate the large shrimps for breeding, because the individual differences are too large, which will cause a sudden drop in breeding density. Through the capture of the camera 7 and the terminal analysis, the system can be effectively monitored and warned in real time.

[0040] The multi-layer hiding nest 3 is an independent design. The top cover A2 is provided with a handle for easy grasping. The top cover A2 is slightly wider than the box A1 and can be directly placed on the crossbeam 2 and fixed with bolts. The box A1 has a porous partition A3, which is convenient for Macrobrachium rosenbergii to hide and live. The porous structure is to allow some sediment to fall to the bottom of the pool. The hiding grooves A4 are installed on both sides of the box A1. The hiding grooves must be smooth and free of burrs, because the shrimps after molting will randomly fall to one place due to stress bouncing. Since the light inside the pool is dim, there is a certain probability that the molting shrimps can avoid being eaten by other shrimps.

[0041] The breeding density of the present invention is improved. In view of the fact that the crayfish is susceptible to the residual food of other organisms and the same species when molting, a multi-layer and multi-layer avoidance nest is specially designed. The multi-layer avoidance groove adopts a rectangular body structure that matches the rectangular pool body, and forms a layout distributed vertically and horizontally along the X and Y directions in the pool, providing a habitat for the crayfish to molt and a space for bouncing and avoiding, and finally greatly improving the breeding density of the crayfish recirculating water culture; the multi-layer avoidance nest is an independent structure, made of acrylic material, light in weight, and provided with a handle, which can be easily extracted and arranged, and can be used for the structural optimization of various fish ponds, and is convenient for disassembly and cleaning. The addition of a multi-layer avoidance nest can increase the plane utilization area of ​​the fish pond by 2 times, and at the same time provide a safe space for shrimps in the molting period, so that the survival rate is increased by 50% (the system survival rate can reach more than 75%, effectively improving the yield and breeding benefits, and can achieve four crops a year, helping efficient and sustainable crayfish production). The feeding amount is accurate and uniform: the feeding amount is precisely controlled. This uniform feeding method will not cause feed waste, and will also improve the uniformity of shrimp growth, making the shrimp of the same size and size, improving the overall farming efficiency. High-density recirculating water farming uses less water and is highly efficient; the system integrates artificial intelligence feeding and alarm functions, which improves the intelligence and management efficiency of the farming process, reduces manual intervention, and achieves scientific farming. This model is suitable for promotion and use in inland areas, effectively solving the problem of local fresh shrimp supply, meeting the market demand for Macrobrachium rosenbergii in Xinjiang, Ningxia and other places, helping farmers increase their income, and promoting the development of Macrobrachium rosenbergii farming industry.

[0042] The above are preferred embodiments of the present invention. A person skilled in the art may make various changes or improvements on this basis. Without departing from the general concept of the present invention, these changes or improvements should fall within the scope of protection claimed by the present invention.
