Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, specifically to a method and apparatus for domesticating Yao's plateau loach. Background Technology

[0002] *Triplophysayaopeizhii*, belonging to the order Cypriniformes, family Cobitidae, subfamily Triplophyinae, and genus *Triplophys*, is one of the main native fish species in the Jinsha River basin and plays an important role in the Jinsha River's aquatic ecosystem. The Jinsha River, the upper reaches of the Yangtze River, has a vast basin area spanning a wide range of latitudes and longitudes, with complex topography and abundant water resources, providing a rich and diverse aquatic environment for the evolution of numerous organisms, including *Triplophysayaopeizhii*. However, in recent years, the development and construction of hydropower stations on the Jinsha River, while promoting economic development, have also brought many challenges to the stability of the ecosystem. In addition, the natural ecological environment of the Jinsha River basin is fragile, facing long-term pressures such as overfishing and invasive alien species, leading to a sharp decline in the population of native fish species such as *Triplophysayaopeizhii*. Because *Triplophysayaopeizhii* prefers to inhabit cold, shallow waters and grows slowly, its population is difficult to recover once destroyed; therefore, conservation efforts for *Triplophysayaopeizhii* are urgently needed.

[0003] The most important aspect is the artificial breeding of *Leptobrachium yaoense*, aiming to cultivate more fry and increase the population of *Leptobrachium yaoense* in the Jinsha River through stock enhancement and release, thereby effectively protecting fishery resources and maintaining the stability of the aquatic ecosystem. However, existing artificial breeding facilities for *Leptobrachium yaoense* are lacking. Directly using other aquaculture equipment cannot simulate the growth environment of *Leptobrachium yaoense*: flowing, shallow water is insufficient to meet its feeding requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a method and device for domesticating Yao's plateau loach, which can simulate the flowing water environment in which Yao's plateau loach grows, is suitable for the growth of Yao's plateau loach, and makes artificial breeding highly efficient.

[0005] To address the aforementioned technical problems, this invention provides a method for domesticating Yao's plateau loach, comprising the following steps:

[0006] To simulate the growth environment of the Yao's plateau loach, a low-temperature, flowing aquaculture water body was established, with a water depth of 10-20 cm and a temperature of 10-20℃.

[0007] In the above-mentioned method, by simulating the growth environment of Yao's Plateau Loach, a low-temperature, flowing aquaculture water body is established to better cultivate Yao's Plateau Loach.

[0008] Furthermore, the flow rate of the aquaculture water is 1.0–2.0 cm / s, allowing the Yao's Plateau Loach to grow in flowing water, which is closer to its natural growth environment.

[0009] To address the aforementioned technical problems, this invention provides a breeding device for *Leptodon yaoi* based on the domestication of *Leptodon yaoi*, comprising a breeding tank, a return water pool, and a water circulation device. The breeding tank has an elongated cavity with a circulating return water pipe at one end and an outlet window at the other end. The return water pool is located on one side of the outlet window, and the height of the return water pool is lower than that of the breeding tank cavity. The breeding water flowing out of the outlet window can flow into the return water pool. The water circulation device is used to return the water in the return water pool to the breeding tank through the circulating return water pipe, so that the breeding water circulates repeatedly within the breeding tank from one end to the other, forming a low-temperature, flowing breeding water body that simulates the growth environment of *Leptodon yaoi*.

[0010] In the aforementioned Yao's Plateau Loach domestication device, the aquaculture water flowing out of the breeding tank is returned to the breeding tank through a water circulation device, so that the aquaculture water flows repeatedly from one end to the other in the breeding tank, establishing a low-temperature, flowing aquaculture water body, thereby simulating the flowing water growth environment of Yao's Plateau Loach, improving the breeding quality. Moreover, the aquaculture water is low-temperature water, and recycling can reduce equipment energy consumption, save water, and save operating costs.

[0011] Furthermore, the breeding tank, the return water tank, and the water circulation device are all located within a space with a constant temperature range. Within this constant temperature space, the temperature of the circulating breeding water can be kept constant within a lower set range, eliminating the need for repeated cooling and reducing energy consumption.

[0012] As an improvement to the Yao's plateau loach domestication device of the present invention, the breeding box is a rectangular box set on the ground; the return water pool is formed by a pit in the ground; multiple breeding boxes are stacked vertically by supports and share a single return water pool and water circulation device. Because the breeding boxes are relatively small, multiple sets can be set up for simultaneous breeding, improving efficiency, and sharing a single return water pool and water circulation device saves space and cost.

[0013] As another improvement to the Yao's Plateau Loach domestication device of the present invention, the breeding box is a rectangular box set on the ground; the return water pool is formed by a depression in the ground. By setting the return water pool below the ground, the water in the breeding box can flow out under the action of gravity, so that the breeding box forms a simulated environment of natural water flow; the return water pool also plays a role in buffering and storing water, ensuring that the water circulation is normal.

[0014] Furthermore, the water outlet window is an elongated opening on the end face of the culture tank, with the height between its top edge and the bottom surface of the culture tank being lower than the depth of the culture water, and the length of the water outlet window being the same as the width of the culture tank. Through the design of the water outlet window, water flows from the culture tank to the return water pool under the influence of gravity, making the water flow in the culture tank similar to natural water flow, thus better simulating the growth environment of the Yao's Plateau Loach.

[0015] As a further improvement of the Yao's Plateau Loach domestication device of the present invention, the water circulation device includes a water pump, the inlet of the water pump is connected to the return water pool, the outlet is connected to the circulation return water pipe, and a filter device is provided on the pipeline connecting the water pump and the breeding box.

[0016] A water pump powers the water circulation, and a filtration system removes impurities and food residue from the aquaculture water, keeping the water clean.

[0017] As an improvement of the Yao's Plateau Loach domestication device of the present invention, the Yao's Plateau Loach domestication device further includes a water supply device, which is used to inject breeding water into the breeding tank through a water injection pipe.

[0018] Furthermore, the water supply device includes a water supply pipeline connected to an external water supply system, as well as a sterilization device and a cooling device installed on the water supply pipeline, so that the aquaculture water entering the aquaculture tank is cooled and sterilized.

[0019] Furthermore, the water supply device also includes an aeration device, which is used to increase the oxygen content of the water flow in the water supply pipeline.

[0020] In summary, the above-mentioned method and device for domesticating Yao's plateau loach can recycle aquaculture water and simulate naturally flowing water in the breeding tank, thus better simulating the flowing water environment for the growth of Yao's plateau loach. The device has low energy consumption, low cost, and high breeding efficiency. Attached Figure Description

[0027] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions of the embodiments are for the purpose of helping to understand the present invention, but do not constitute a limitation thereof.

[0028] Example 1

[0029] The present invention discloses a method for domesticating Yao's plateau loach, comprising the following steps: establishing a low-temperature, flowing aquaculture water body to simulate the growth environment of Yao's plateau loach, wherein the water depth of the aquaculture water body is 10-20cm and the temperature is 10-20℃.

[0030] Optionally, the flow rate of the culture water is 1.0–2.0 cm / s, so that the Yao's plateau loach grows in flowing water, which is closer to its natural growth environment.

[0031] The optimal water depth is 15cm, the optimal flow rate is 1.3mm / s, and the optimal temperature is 15 degrees Celsius. These parameters can be obtained based on observations and tests in nature. Field tests were conducted in the meadow ditches where the Yao's Plateau Loach lives. Water depths were measured at 10-18cm along the way, and water temperature variations were observed between 10 and 18 degrees Celsius over three consecutive days. The water flow was relatively slow. Based on these actual aquaculture conditions, a flow rate of 1.0-2.0cm / s was set to allow the Yao's Plateau Loach to live in an environment similar to its natural growth, thus improving the quality of Yao's Plateau Loach farming.

[0032] Figure 1-4 This invention illustrates a device for domesticating Yao's plateau loach. (Example:) Figure 1As shown, the Yao's plateau loach domestication device includes a breeding tank 1, a return water pool 2, and a water circulation device 3. The breeding tank 1 has a long, narrow cavity, with a circulating return water pipe 12 at one end and an outlet window 11 at the other end. The return water pool 2 is located on one side of the outlet window 11. The height of the return water pool 2 is lower than that of the breeding tank 1, and the breeding water flowing out of the outlet window 11 can flow into the return water pool 2. The water circulation device 3 is used to send the water in the return water pool 2 back to the breeding tank 1 through the circulating return water pipe 12, so that the breeding water circulates repeatedly in the breeding tank 1 from one end to the other, forming a low-temperature, flowing breeding water body that simulates the growth environment of Yao's plateau loach.

[0033] Optionally, filters or other devices are installed at the water outlet 11 to prevent the Yao's plateau loach population from leaving the breeding tank 1.

[0034] Optionally, the breeding tank 1, the return water tank 2, and the water circulation device 3 are all located in a space with a constant temperature range. Since the Yao's plateau loach mainly grows in low-temperature water, this device can be installed indoors with good insulation and no direct sunlight, reducing heat exchange between the low-temperature water and the ambient temperature, avoiding water temperature rise during water circulation, and reducing equipment operating costs.

[0035] like Figure 4 As shown, the breeding box 1 is a rectangular box placed on the ground; the return water pool 2 is formed by a depression in the ground. Multiple breeding boxes 1 are stacked vertically via supports 5, sharing a single return water pool 2 and water circulation device 3. Figure 2 As shown, there are multiple sets of breeding tanks 1, return water tanks 2, and water circulation devices 3 in the horizontal direction, all located within a space with a constant temperature range. Installing multiple sets of breeding tanks 1 simultaneously in the same room improves breeding efficiency and the utilization rate of the constant temperature room, while reducing costs.

[0036] Optionally, the breeding box 1 can be designed with an overall length of 2.4m, a width of 0.6m, a height of 0.6m, and an effective volume of 0.72m³. 3 The breeding boxes 1 are arranged horizontally side by side, 0.2m apart. The return water pool 2 is located below the ground, which allows the water in the breeding boxes 1 to flow out under the action of gravity, so that the breeding boxes 1 form a simulated environment of natural water flow; in addition, the return water pool 2 also plays a role in buffering and storing water, ensuring that the water circulation is normal.

[0037] Optionally, the water outlet window 11 is a long strip-shaped opening on the end face of the culture tank 1, the height between the top edge and the bottom surface of the culture tank 1 is lower than the depth of the culture water, and the length of the water outlet window 11 is the same as the width of the culture tank 1.

[0038] The length of the water outlet window 11 is the same as the width of the breeding tank 1. The water flows from the breeding tank 1 to the return water pool 2 under the action of gravity, making the water flow in the breeding tank 1 similar to the natural water flow, thus better simulating the growth environment of the Yao's plateau loach.

[0039] Optionally, an overflow drain pipe 21 is installed in the return water tank 2. When the liquid level in the return water tank 2 is higher than the set height, the water in the return water tank 2 will flow out from the overflow drain pipe 21. When the water circulation fails or other reasons cause the water in the return water tank 2 to increase rapidly, it can be discharged through the overflow drain pipe 21 to avoid overflowing to the bottom.

[0040] Optionally, the water circulation device 3 includes a water pump 31, the inlet of which is connected to the return water tank 2, and the outlet of which is connected to the circulation return water pipe 12. A filter device 32 is installed on the pipe connecting the water pump 31 and the breeding tank 1 to keep the water clean.

[0041] Optionally, the Yao's plateau loach domestication device also includes a water supply device 4, which is used to inject aquaculture water into the breeding tank 1 through the water injection pipe 13. Since the aquaculture water of this device can be recycled, it only needs to be injected when used for the first time, or when the water depth of the breeding tank 1 is insufficient.

[0042] Optionally, the water supply device 4 includes a water supply pipeline 41 connected to an external water supply system, and a sterilization device 42 and a cooling device 43 installed on the water supply pipeline 41, so that the aquaculture water entering the aquaculture tank 1 is cooled and sterilized. The water supply device 4 also includes an aeration device 44, which is used to increase the oxygen content of the water flow in the water supply pipeline 41.

[0043] The sterilization device 42 can use an ozone generator to inject ozone into the water supply pipe 41 to achieve sterilization. The cooling device 43 can use a refrigeration system to locally cool the pipes, reducing the temperature of the flowing water. The suitable water temperature is 10-20℃, with the optimal temperature being 14-16℃. The filtration device 32 uses a conventional water filter or water filter tank to separate water from impurities. The filtered water is returned to the breeding tank 1, and the impurities can be discharged through the drain pipe 33. The aeration device 44 introduces external oxygen into the water supply pipe 41 through aeration micropores to increase the oxygen content.

[0044] The filter device 32 can be adopted as follows: Figure 3 The filter tank structure shown has a water pump 31 that draws water into the filter tank through the inlet 321. The water flows sequentially through coarse and fine filter cotton 323, biochemical cotton 324, and ultraviolet lamp 325, and finally flows out through the outlet 322. The coarse and fine filter cotton 323 filters impurities, which can be discharged through the drain outlet 326. The biochemical cotton 324 cultivates nitrifying bacteria to decompose feces and harmful substances. The ultraviolet lamp 325 inhibits bacteria in the water.

[0045] Optionally, the water supply pipe 41 has a diameter of 9cm, the water injection pipe 13, the circulating water return pipe 12 and the sewage pipe 33 all have a diameter of 5cm, and the pipe that connects multiple sewage pipes 33 is the main sewage pipe with a diameter of 11cm.

[0046] When using it, first: turn on the aeration device 44 to collect aeration water in the water supply pipeline 41; the aeration water enters the cooling device 43 to make the water flow into a low temperature state of 14-16℃; turn on the ozone generator switch to sterilize the cooled water and complete the preparation of the water intake for aquaculture.

[0047] Then: The treated aquaculture water is transported to the aquaculture tank 1 through the water injection pipe 13. At this time, the water outlet window 11 is closed first, and the set amount of aquaculture water is injected into the aquaculture tank 1. Usually, the water level in the aquaculture tank 1 is first raised to 40-60cm.

[0048] Next: Open the water outlet window 11 to allow the water in the breeding tank 1 to flow into the return water tank 2. When the liquid level in the return water tank 2 reaches the set height, start the water circulation device 3 to return the breeding water in the return water tank 2 to one end of the breeding tank 1, thereby allowing the breeding water to circulate repeatedly in the breeding tank 1 from one end to the other.

[0049] During the reflux process, the water in the return water tank 2 first enters the filter tank, and the waste residue in the aquaculture water is removed through the filtration and sewage discharge action. It can be discharged through the sewage outlet 326 and the sewage pipe 33 to achieve the purpose of waste discharge. At the same time, the aquaculture water with the waste residue removed is transported back to the aquaculture tank 1 through the circulating return water pipe 12 to realize cold water recovery and recycling. The filter tank is cleaned regularly to ensure filtration efficiency.

[0050] Finally: Place the Yao's Plateau Loach into breeding box 1, add the breeding population, and begin breeding.

[0051] This device can control the water temperature for aquaculture, and through the filtration and sewage discharge of the filter tank and the cold water recovery of the water pump 31, it maintains the flow of water throughout the device, effectively simulating the living environment of Yao's Plateau Loach in natural water bodies. It also recycles the cooled aquaculture water, ensuring a suitable water temperature and good water quality in the breeding tank 1, reducing the energy consumption of the entire device, greatly reducing production costs, and making it suitable for the large-scale domestication and breeding of Yao's Plateau Loach.

[0052] 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 its scope of protection. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that after reading the present invention, they can still make various changes, modifications or equivalent substitutions to the specific implementation of the invention, but these changes, modifications or equivalent substitutions are all within the scope of protection of the pending claims of the invention.
