Description

A method for constructing artificial breeding nests for crayfish in sandy soil in arid Northwest China Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to a method for making artificial breeding nests for crayfish in sandy soil in arid areas of Northwest China. Background Technology

[0002] With societal development, people's demands for food are increasing, with higher expectations for the nutritional value and health benefits of ingredients. Crayfish, due to their delicious meat and high nutritional value, are widely loved by young people, leading to the rapid development of the crayfish farming industry. In recent years, more and more people have started farming crayfish, resulting in a year-on-year increase in demand. Because crayfish are averse to light, farms typically provide them with shaded areas. In crayfish farming, habitats are placed in the ponds, mainly consisting of piles of dead branches. However, these branches rot in water over time, affecting water quality and cannot be recycled. Alternatively, artificial nests can be built using mud in the ponds. However, mud nests not only make the water turbid but also take a long time to construct. Adding artificial nests based on crayfish farming density requires significant time.

[0003] While current technologies provide a foundation for crayfish breeding, traditional methods of artificial nest construction are labor-intensive, inefficient, and struggle to ensure nest consistency and stability. Furthermore, research on the unique environment of sandy soil in the arid Northwest region is relatively limited. The poor water retention and high permeability of sandy soil impose special requirements on nest construction materials, structures, and maintenance methods, necessitating further improvement. Therefore, a more suitable crayfish breeding nest design is urgently needed to address the prominent problems in artificial breeding nests for native Xinjiang crayfish in the sandy soil of the arid Northwest region, resolving the aforementioned technical challenges. Summary of the Invention

[0004] In view of the shortcomings of the above-mentioned technologies, such as the inability of traditional crayfish breeding nests to provide a suitable growth environment for crayfish in sandy soil water bodies, the present invention provides a method for making artificial breeding nests for crayfish in sandy soil in arid areas of Northwest China.

[0005] To achieve the above objectives, this invention provides a method for constructing artificial breeding nests for crayfish in sandy soil in arid Northwest China, comprising the following steps:

[0006] S1. First, cut a section of opaque tube as the breeding tube for crayfish, and make openings at both ends of the breeding tube for crayfish to enter and exit the breeding tube.

[0007] S2, set up flow holes on the breeding tube to enhance the flow of water in the breeding tube, and then set up a breeding net between two identical breeding tubes. Fix the breeding net to the breeding tube with PP cable ties to form a breeding device.

[0008] S3: Multiple breeding devices are stacked to form a breeding nest, and a baffle is set on each side of the breeding nest to block crayfish.

[0009] As an improvement of the present invention, the breeding tube is a tube segment with a diameter of 50-75mm and a length of 30cm.

[0010] As an improvement of the present invention, the breeding tube is made of PVC pipe.

[0011] As an improvement of the present invention, the flow holes are arranged at 5cm intervals along the length of the breeding tube, and the diameter of the flow holes is 5mm.

[0012] As an improvement of the present invention, the breeding net is a mesh with a width of 30mm and a length of 100mm.

[0013] As an improvement of the present invention, the breeding net is a stacked net sheet with a mesh diameter of 0.05 mm.

[0014] As an improvement of the present invention, the breeding net and the breeding tube are bound and fixed together by PP cable ties.

[0015] The beneficial effects of this invention are as follows: Compared with the prior art, this invention provides a method for constructing artificial breeding nests for crayfish farming in sandy soil in arid Northwest China. The artificial breeding nests are formed by stacking multiple breeding devices. Each breeding device includes a breeding tube with an entrance / exit for crayfish on one side. The breeding tube has strip-shaped through holes and multiple flow holes along its length. At least two breeding tubes are arranged opposite each other, and both ends of a breeding net pass through the strip-shaped through holes of the two breeding tubes respectively. The breeding net and the breeding tubes are fixed together with cable ties. By stacking multiple breeding devices... This invention creates an ecosystem for crayfish farming nests. The breeding device is simple to manufacture and has low production costs. Furthermore, its structural design is suitable for the aquatic environment of arid Northwest China, providing a favorable environment for crayfish growth and reproduction without polluting the water. This generates economic benefits for crayfish farmers. The PVC pipe used in this invention, with its flow holes, ensures the water retention and stability of the breeding device, effectively solving the problems faced by traditional nests in sandy water bodies and improving crayfish breeding efficiency and survival rate.

[0022] To more clearly illustrate the present invention, the invention will be further described below with reference to the accompanying drawings.

[0023] In the following description, specific examples are given to provide a more in-depth understanding of the invention. It is obvious that the described embodiments are merely some, not all, of the embodiments of the invention. It should be understood that the specific embodiments described are for illustrative purposes only and are not intended to limit the scope of the invention.

[0024] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0025] Because existing technologies cannot guarantee the breeding and reproduction of crayfish in the special environment of sandy soil in the arid Northwest region, traditional crayfish breeding nests are not suitable. Compared with soil, sandy soil in the Northwest region has poor water retention, which easily leads to water loss. At the same time, its permeability is even worse. Traditional breeding nests cannot maintain a constant internal temperature, making it difficult to provide a good growth environment for crayfish. Therefore, this invention provides a method for making artificial breeding nests for crayfish in sandy soil in the arid Northwest region to solve the above-mentioned technical problems.

[0026] Please refer to Figures 1-4. A method for constructing artificial breeding nests for crayfish in sandy soil in arid Northwest China, according to the present invention, includes the following steps:

[0027] S1. First, cut a section of opaque tube as the breeding tube 1 for crayfish, and make openings at both ends of the breeding tube 1 for crayfish to enter and exit the breeding tube 1.

[0028] S2, set flow holes 3 and strip-shaped through holes 4 on the breeding tube 1 to enhance the flow of water in the breeding tube 1, and then set a breeding net 2 between two identical breeding tubes 1. The two ends of the breeding net pass through the strip-shaped through holes 4 of the two breeding tubes respectively. Fix the breeding net 2 to the breeding tube 1 with PP cable ties to form a breeding device.

[0029] S3, multiple breeding devices are stacked to form a breeding nest, and a baffle 5 is set on each side of the breeding nest to block crayfish.

[0030] Due to the light-avoiding characteristics of crayfish, openings are provided at both ends of the breeding tube 1 for crayfish to enter and exit. The breeding tube 1 should be made of a pipe with low light transmittance to ensure that crayfish can enter the tube and live there for a long time. After the crayfish enter the breeding tube 1, the crayfish carrying eggs will detach the eggs from the mother on their own and fall through multiple flow holes 3 on the breeding tube 1 to attach to the breeding net 2 for incubation. The breeding net 2 can prevent the hatched crayfish from escaping and does not affect the normal flow of water. It maintains the flow of the breeding device and ensures that the crayfish can grow and develop normally in the breeding device. The breeding device of the present invention can form crayfish nests by stacking, which can cover a large area of ​​the bottom of the water, or multiple breeding devices can be laid flat on the bottom surface.

[0031] In an embodiment of the present invention, the breeding tube 1 is a PVC pipe segment with a diameter of 50-75mm and a length of 30cm. Since the normal size of crayfish is between 50-75mm, the diameter of the breeding tube is configured to match the size of the crayfish. Because the PVC material breeding tube 1 is generally inexpensive in terms of production and manufacturing costs, and is suitable for long-term use in water or humid environments, it has good corrosion resistance and heat insulation properties, and does not release harmful substances such as formaldehyde and heavy metals. It has an environmental protection effect on maintaining the ecological environment of the water body, and is suitable as a breeding nest for crayfish, especially suitable for the water environment of the arid Northwest region.

[0032] Since there is a lot of gravel, crayfish need to reproduce and thrive in the breeding tube 1. The flow holes 3 are set at 5cm intervals along the length of the breeding tube 1, and the diameter of the flow holes 3 is 5mm. By setting the flow holes 3 with a diameter of 5mm, the water in the tube can flow normally, ensuring the flow between water bodies. This allows the water in the breeding tube 1 to be constantly renewed and flowing, increasing the dissolved oxygen in the tube, increasing the water retention of the breeding device, and the flowing water will carry away the feces or foreign objects excreted by the crayfish, creating a more suitable growth environment for the crayfish.

[0033] In an embodiment of the present invention, the breeding net 2 is a stacked net sheet with a width of 30mm and a length of 100mm. The mesh diameter of the net sheet is 0.05mm. Due to the poor water quality in the Northwest region, most of the water consists of fine gravel, with a diameter generally ranging from 1mm to 0.05mm. The mesh size of ordinary breeding net 2 sheets is larger than that of gravel. In flowing water, gravel will pass through the mesh of breeding net 2 and slowly accumulate and cover the shrimp eggs that have fallen from the crayfish, preventing the shrimp eggs from hatching successfully and causing certain economic losses to farmers. Therefore, configuring the mesh diameter of breeding net 2 to 0.05mm can block most of the gravel from passing through, ensuring that the shrimp eggs can hatch normally.

[0034] The breeding net 2 and the breeding tube 1 are tied and fixed together with PP cable ties. The PP cable ties can be used to connect and fix different breeding devices, and the distance between different breeding devices can be adjusted to ensure the stability and consistency of the breeding nests.

[0035] In this embodiment, in order to make the environment of the breeding device more suitable for crayfish breeding, baffles 5 are provided on both sides of the breeding device. By setting baffles 5, crayfish eggs can be prevented from escaping, and the light-blocking and heat-preserving properties of the breeding device can be increased, so that crayfish can live stably in the breeding device.

[0036] The advantages of this invention are:

[0037] 1. The breeding device of the present invention is simple to manufacture and has low production cost. At the same time, the structural design of the breeding device is suitable for the water environment in the arid Northwest region, and can provide a good growth and reproduction environment for crayfish.

[0038] 2. The breeding tube made of PVC pipe of the present invention has flow holes on the breeding tube to ensure the water retention and stability of the breeding device, effectively solving the problem faced by traditional nests in sandy soil and water, and improving the breeding efficiency and survival rate of crayfish.

[0039] The above-disclosed embodiments are merely a few specific examples of the present invention, but the present invention is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
