Description

Technical Field

[0001] This invention relates to the field of breeding equipment technology, and in particular to an artificial, eco-friendly, natural breeding device and method for amphibians. Background Technology

[0002] The Zhenhai spiny salamander is a rare amphibian endemic to China and is listed as a Class I protected wild animal in China. Its wild population is extremely small, distributed only in Zhenhai District of Ningbo City, Zhejiang Province and a very small area around it. Due to factors such as habitat fragmentation, increased human interference, and low success rate of natural reproduction, the population is facing a serious survival crisis and urgently needs to expand its population through artificial breeding technology in order to achieve effective protection and recovery of the species.

[0003] In its natural environment, the reproductive process of the Zhenhai spiny newt exhibits highly specific requirements for habitat conditions. Its reproductive cycle involves four key stages: terrestrial spawning, egg hatching, aquatic larval development, and adult migration to land. Each stage is strictly dependent on factors such as temperature, humidity, water quality, light, concealment, and food resources within the microhabitat. However, due to global climate change, habitat destruction, and water pollution, habitats meeting these reproductive conditions in the wild are continuously shrinking, resulting in a natural reproduction rate of less than 5% for the Zhenhai spiny newt, and its natural population regeneration capacity is on the verge of collapse.

[0004] To save the species, research has been conducted on artificial breeding techniques for the Zhenhai spiny salamander. However, existing artificial breeding methods mostly involve artificial propagation in indoor breeding devices, followed by release into the wild after the animals have developed into adults. These breeding devices are not only costly, but the labor costs for releasing the adults are also relatively high. Furthermore, adults developed in these devices have a relatively weak ability to adapt to the natural environment after being released into the wild. Summary of the Invention

Furthermore, the terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit the scope of this application.

[0038] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0039] like Figure 1 , Figure 2 , Figure 3 As shown, an artificial, simulated natural breeding device for amphibians includes a breeding pond 1, which comprises a pond body 11 made of stainless steel, exhibiting excellent corrosion resistance. The stainless steel is 3mm-5mm thick, and the pond body 11 is 3m-5m long and 2m-3m wide. A breeding area 12, with a rectangular structure, is located in the center of the pond body 11. Inclined crawling areas 14, with a frosted surface, are located on both sides of the breeding area 12, facilitating the easy exit of adults breathing through gills from the pond body 11. The crawling areas 14 are connected to the breeding area 12 via a transition area 13. The angle between the crawling areas 14 and the ground is 10°-20°, and the angle between the crawling areas 14 and the transition area 13 is 130°-180°, facilitating the exit of juveniles.

[0040] like Figure 4 As shown, the bottom layer of the breeding area 12 is a compacted soil layer 123. Above the soil layer 123 is a silt layer 124, which provides food for the animals. The silt layer 124 contains insect eggs that provide food for the developing *Echinochloa crus-galli*. Above the silt layer 124 is a layer of dead leaves 125, which provides a hiding area for the larvae of *Echinochloa crus-galli*. Above the dead leaves layer 125 is a still water layer 126. In this embodiment, the soil layer 123 is 20 cm thick, the silt layer 124 is 40 cm thick, the dead leaves layer 125 is 5 cm thick, and the still water layer is 30 cm thick.

[0041] like Figure 9 As shown, several breeding frames 15 for animal reproduction are arranged along the length of the pool body 11 between the crawling area 14 and the transition area 13. During their reproductive period, the Zhenhai spiny salamander enters the breeding frame 15 from the land via the crawling area 14 and lays its eggs within the breeding frame 15. The bottom of the breeding frame 15 is provided with a flow hole 122 communicating with the rearing area 12, located within the still water layer 126. Water in the still water layer 126 enters the breeding frame 15 through the flow hole 122, providing sufficient moisture for egg development. Crawling pathways are provided between the breeding frames 15 for adult animals to return to the land surface. Adults that have completed development in the pool body 11 crawl back to land via the crawling area 14 and the transition area 13.

[0042] The top of the breeding frame 15 has an opening, and a vertical section 120 is provided on the side of the breeding frame 15 near the still water area, with an outflow hole 122 located on the vertical section 120. The interior of the breeding frame 15 is filled with filter sand 127, which filters the water entering the breeding frame 15. A filter screen is provided at the outflow hole 122 to prevent the filter sand from flowing from the breeding frame 15 into the breeding area 12. The top of the filter sand 127 is covered with dead leaves, and aquatic plants that provide shade and shelter are planted inside the filter sand 127. Both the plants and the dead leaves provide shelter, shade, and warmth. An outflow hole 128 is provided at the top of the vertical section 120 to facilitate the entry of larvae into the pool 11. The outflow hole 128 is located at the position of the dead leaves, allowing larvae hatching inside the dead leaves to enter the pool 11 by means of the water ripples within the pool 11. The top of the filter sand 127 is a slope that gradually slopes downward from the outside to the inside. The top of the slope is fixed by a fixing net, so that water can enter the filter sand 127 on the side close to the still water layer 126, while the other side is not submerged, which facilitates the hatching of eggs and the jumping of larvae into the water.

[0043] Several diversion plates 16 are evenly distributed on the upper surface of the crawling area 14 to block water from the breeding frames 15, reducing the scouring of eggs within the breeding frames 15 by runoff and improving the survival rate. Several parallel diversion plates 16 are located above the breeding frames 15. Several flow-slowing blocks 17 are evenly distributed on the upper surface of the crawling area 14 to buffer the runoff from the surface of the abrasive layer.

[0044] like Figure 5 , Figure 6 As shown, the rearing area 12 is equipped with a hiding structure for juveniles. The hiding structure includes a support rod 19, on which several hiding umbrellas 18 are fixedly mounted. The hiding umbrellas 18 can be made of corrosion-resistant plastic. A connecting rod 110 is fixedly mounted at the bottom of the pool body 11, with each connecting rod 110 corresponding to one of the hiding umbrellas 18. The connecting rod 110 is connected to the support rod 19 via a connector.

[0045] like Figure 7As shown, the connector includes a connecting seat 111, with a connecting block fixedly mounted on the top of the connecting seat 111. The connecting seat 111 is fixedly connected to the support rod 19 via the connecting block. The connecting block and the support rod 19 can be connected by a threaded connection, facilitating the assembly of the support rod 19 and the connector. A slider 112 is slidably mounted inside the connecting seat 111, and a first spring 113 is provided between the slider 112 and the connecting seat 111 to apply an outward pushing force to the slider 112. Several locking blocks 116 are hinged to the slider 112. An inclined surface is provided on the bottom outer surface of the connecting seat 111 to push the locking blocks 116 to rotate. A locking platform 117 is fixedly mounted on the top of the connecting rod 110, and the connecting seat 111 drives the locking blocks 116 to rotate and lock them onto the locking platform 117 via the inclined surface. A torsion spring is provided on the pivot shaft where the locking blocks 116 and the slider 112 are hinged, causing one end of the locking blocks 116 to move away from the locking platform 117, facilitating the separation of the locking blocks 116 from the locking platform 117.

[0046] like Figure 8 As shown, a locking structure is provided between the connecting seat 111 and the support rod 19 to lock the connecting seat 111. The locking structure includes several insert rods 114 fixedly disposed on the lower surface of the connecting seat 111, and a slot 115 adapted to the insert rods 114 is provided on the locking platform 117 at the top of the connecting rod 110. The insert rods 114 are located in the slots 115. A locking pin 118 is slidably disposed on the locking platform 117, and a locking hole is provided on the insert rod 114. A second spring 119 is provided between the locking pin 118 and the locking platform 117 to allow the locking pin 118 to be inserted into the locking hole. The connecting seat 111 and the locking platform 117 are fixed by the locking pin 118 and the locking hole, so that the locking block 116 is stably locked on the locking platform 117, improving the stability of the connection between the support rod 19 and the connecting rod 110.

[0047] like Figure 10 As shown, a protective mechanism 2 is installed on the exterior of the breeding pond 1. The protective mechanism 2 includes a base 21, which is fixed to the ground. A column 22 is installed in the middle of the base 21, and a support structure is installed on the column 22. A protective net 23 is installed on the support structure. The protective net 23 is unfolded by the support structure, facilitating its installation. The column 22, base 21, and support structure are all made of stainless steel. The edge of the protective net 23 is fixed to the base 21 with a flexible rope, and a passage for adults to pass through is provided between the bottom edge of the protective net 23 and the base 21. The protective net 23 protects against natural enemies of the *Zhenhai spiny newt*, such as dragonflies, and protects the larvae of the *Zhenhai spiny newt*, improving their survival rate.

[0048] like Figure 11As shown, the support structure includes two opposing support units. Each support unit includes a first link 25, a second link 26, and a third link 27 connected end-to-end. One end of the first link 25 is equipped with a first gear 28 that drives the first link 25 of the other support unit. A motor 24 is mounted on the column 22 to rotate the first link 25. The motor 24 drives the first link 25 to rotate, and the first link 25 drives the other first link 25 via the first gear 28, achieving synchronous operation of the two support units. The other end of the first link 25 meshes with a third gear 210 at one end of the second link 26 via a second gear 29. A fourth gear 211 at the other end of the second link 26 meshes with a fifth gear 212 at one end of the third link 27. The first link 25 and the second link 26 are hinged together by a first connecting plate 214. The two ends of the first connecting plate 214 are fixedly equipped with opposing first vertical plates 215 and second vertical plates 216. The first vertical plate 215, the first connecting rod 25, the column 22, and the first transmission rod 213 form a parallelogram, ensuring that the first connecting plate 214 remains vertical and enabling synchronous transmission between the first connecting rod 25 and the second connecting rod 26. The second connecting rod 26 and the third connecting rod 27 are hinged together by the second connecting plate 218, on which the third vertical plate 219 is fixedly mounted. The second vertical plate 216, the second connecting rod 26, the third vertical plate 219, and the second transmission rod 217 form a parallelogram, ensuring vertical movement of the second connecting plate 218 and enabling smooth transmission between the second connecting rod 26 and the third connecting rod 27. The protective net 23 is unfolded and laid above the pool body 11 via the first connecting rod 25, the second connecting rod 26, and the third connecting rod 27.

[0049] To ensure the water volume in the pool 11, an inlet pipe can be installed inside the pool 11 to inject water into the pool 11, thus ensuring the water volume in the pool 11.

[0050] The breeding method based on the above-mentioned artificial ecological natural breeding device for amphibians includes the following steps:

[0051] S1. Excavate a foundation pit on land and place the pool body 11 into the pit. Fill the bottom of the pool body 11 with soil layer 123 and compact it. Lay a silt layer 124 and a dead leaf layer 125 on top of the soil layer 123 and fill it with water. Fix the base 21 on the land, deploy the protective mechanism 2 above the pool body 11, and cover the pool body 11 with protective netting 23.

[0052] S2. Adults in their reproductive period enter the breeding box 15 from the land via the reptile area 14, where they reproduce. Water in the still water layer 126 enters the breeding box 15 through the flow hole 122 and is filtered through the sand layer 127, providing moisture for the eggs to hatch. Dead leaves and green plants in the breeding box 15 provide shelter for the eggs.

[0053] S3. The eggs develop in the breeding frame 15. After hatching, the eggs crawl out from the exit hole 128 and enter the still water layer 126 to undergo metamorphosis. The dead leaves and hiding umbrellas 18 in the pool 11 provide hiding and shade places for the larvae, and the insect eggs in the silt provide food for the larvae.

[0054] S4. After the larvae have developed in pool 11, they crawl out of pool 11 and onto land through transition zone 13 and crawling zone 14.

[0055] Therefore, the artificial, eco-friendly natural breeding device and method for amphibians described in this invention can solve the problems of high cost and poor environmental adaptability of the existing artificial propagation of Zhenhai spiny salamander.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. 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 still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.

8. A breeding method based on the artificial, eco-friendly, natural breeding device for amphibians as described in claim 7, characterized in that: Includes the following steps: S1. Excavate a foundation pit on land, place the pool into the pit, fill the bottom of the pool with soil and compact it, lay a layer of silt and dead leaves on top of the soil, and fill it with water; fix the base on land, deploy the protective mechanism above the pool, and cover the pool with a protective net. S2. During the reproductive period, adults enter the breeding box from the land through the reptile area and reproduce in the breeding box. Water in the still water layer enters the breeding box through the flow hole and is filtered by the filter sand to provide moisture for the eggs to hatch. The dead leaves and green plants in the breeding box provide shelter for the eggs. S3. The eggs develop in the breeding box. After hatching, the eggs crawl out from the hatch and enter the still water layer to undergo metamorphosis. The dead leaves and shading umbrellas in the pool provide hiding places and shade for the larvae, while the insect eggs in the silt provide food for the larvae. S4. After the larvae have developed in the pool, they crawl out of the pool and onto land through the transition zone and crawling zone.
