Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and in particular to a Huangshi scad culture device and method. Background Art

[0002] The Yellowstone Crawler (Euchiloglanis kishinouyei), a member of the order Siluriformes, family Euchiloglanidae, genus Euchiloglanis, also known locally as "stone crawler" and "grouper catfish," is endemic to the upper Yangtze River. Its unique habitat, reproductive habits, and evolutionary status make it the most primitive species of catfish, aside from the genus Protocatechus, making it an important subject for studying fish evolution. The Yellowstone Crawler is found in the Jinsha and Minjiang River systems of the upper Yangtze River. It is a small to medium-sized benthic fish that often crawls on river gravel beaches and feeds on aquatic insects and their larvae.

[0003] In recent years, the construction of cascade water conservancy projects in the upper reaches of the Yangtze River has destroyed the habitat of the Yellowstone catfish. Coupled with increasing human fishing, the wild germplasm resources of the Yellowstone catfish have declined sharply, and the population has plummeted, currently endangered. The low temperatures of the plateau environment where it lives result in slow growth and a long time to sexual maturity, making it difficult for the damaged population to recover spontaneously under natural conditions. Therefore, the protection of the Yellowstone catfish is particularly important and urgent. Artificial propagation of the Yellowstone catfish aims to produce more seedlings and restore and replenish its wild population. The effective implementation of these fishery resource protection measures can effectively protect fishery resources and maintain the stability of aquatic ecosystems.

[0004] Due to the lack of domesticated Yellowstone catfish, current artificial breeding of Yellowstone catfish requires only natural populations from their natural water habitats, requiring conditions similar to their natural environment to adapt to their living habits. Due to their benthic nature, Yellowstone catfish require flowing water at the bottom of the culture area. Existing aquaculture systems, such as conventional ponds without significant water flow and recirculating aquaculture systems that pump water through culture tanks, lack significant bottom water flow and are therefore unsuitable for artificial breeding of Yellowstone catfish. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a device and method for breeding yellow stone catfish, which provide a stable flowing water body for yellow stone catfish at the bottom of the breeding water body and improve the breeding quality.

[0006] In order to solve the above technical problems, the present invention provides a Huangshi climbing catfish breeding device, including a breeding box, a partition is provided inside the breeding box, the partition separates the breeding box into a water inlet tank and a breeding tank, a plurality of water holes are provided at intervals at the bottom end of the partition, a water outlet hole is provided on the bottom surface of the breeding tank away from the partition, and the water inlet tank is connected to a water inlet pipe.

[0007] In the above-mentioned Yellowstone catfish breeding device, the water in the water inlet tank flows into the breeding tank through the water hole. Since the water hole and the water outlet hole are both located at the bottom layer of the water flow in the breeding tank, a stable flowing water body is generated at the bottom layer of the breeding water in the breeding tank, simulating the water environment suitable for the life of Yellowstone catfish and improving the breeding quality.

[0008] As an improvement to the Huangshi climbing catfish breeding device of the present invention, during breeding, the liquid level of the water inlet tank is higher than that of the breeding tank, so that the water in the water inlet tank can automatically flow into the breeding tank through the water hole at a certain flow rate, and a flowing water body can be generated at the bottom of the breeding water body.

[0009] As another improvement of the Huangshi climbing catfish breeding device of the present invention, the top surface of the breeding bin is open, and the top surface of the water inlet bin is provided with a closed cover.

[0010] By closing the cover plate to form a closed space in the water inlet bin, the pressure in the water inlet bin can be changed by controlling the water flow rate of the inlet pipe, and then the water flow rate out of the water hole can be adjusted, and finally the flow rate of the aquaculture water in the breeding bin can be adjusted to meet the water flow rate requirements of the Yellowstone catfish.

[0011] Furthermore, a regulating valve is provided on the water inlet pipe to adjust the pressure within the water inlet tank, thereby adjusting the water outflow rate of the water outlet. The regulating valve can be a pressure regulating valve or a flow regulating valve. The regulating valve controls the flow rate of the water inlet pipe, thereby adjusting the water outflow rate of the water outlet, and thus adjusting the bottom water flow rate in the aquaculture tank.

[0012] As another improvement to the Huangshi climbing catfish aquaculture device of the present invention, the water holes are evenly spaced along the length of the bottom end of the partition plate to form a long fish comb structure. The fish comb structure has a simple structure and uniform flow distribution, generating a uniform water flow at the bottom of the aquaculture water body.

[0013] Furthermore, the breeding box is rectangular, and the water hole is rectangular. The long side and wide side of the water hole are parallel to the long side and wide side of the breeding box respectively. Compared with the round hole, the water flow out of the rectangular hole is more uniform and stable.

[0014] As another improvement of the Huangshi climbing catfish breeding device of the present invention, a water outlet pipe is provided on one side of the breeding box, and the water outlet pipe is an inverted U-shape, including a first pipe section and a second pipe section arranged at intervals, and a third pipe section connecting the first pipe section and the second pipe section, the first pipe section is connected to the water outlet hole, and the second pipe section is connected to a return pipe.

[0015] Preferably, the third pipe section is horizontal and is set at a distance d above the bottom surface of the breeding bin. The value of d determines the height of the liquid level in the breeding box and can be determined according to the living environment of the Yellowstone catfish.

[0016] The inverted U-shaped outlet pipe can effectively control the liquid level in the breeding tank. During the design, the height of the third pipe section relative to the bottom of the breeding tank is designed according to the required liquid level, thereby ensuring that the breeding tank always has an appropriate amount of breeding water.

[0017] Furthermore, the middle portion of the first pipe section is connected to the water outlet pipe, the bottom end of the first pipe section is connected to a sewage pipe, and a sewage valve is provided at the connection between the sewage pipe and the first pipe section.

[0018] By connecting with the water outlet in the middle of the first pipe section, the water flowing out of the water outlet will flow upward into the third pipe section in the first pipe section, and the impurities such as feces carried by it will be precipitated into the lower pipe of the first pipe section. In the breeding process, the sewage valve can be opened regularly to clean the water conveniently and quickly, which is convenient for breeding management.

[0019] Furthermore, the invention further comprises a support on which a plurality of rows of the aquaculture boxes are supported, each row comprising a plurality of vertically spaced aquaculture boxes, and all the aquaculture boxes in each row share a common water inlet pipe, a common return pipe, and a common sewage pipe. Placing multiple aquaculture boxes on the same support conserves space; and each vertical row of aquaculture boxes shares a common water inlet pipe, a common return pipe, and a common sewage pipe, effectively reducing equipment costs, facilitating aquaculture management, and improving aquaculture efficiency.

[0020] In order to solve the above technical problems, the present invention provides a method for cultivating Huangshi scaly catfish based on the above Huangshi scaly catfish cultivation device, comprising the following steps:

[0021] A breeding water body with a water depth of 15 to 25 cm and a water temperature of 10 to 18°C is established in the breeding box, and a row of water inlets are set at the bottom of one end of the breeding water body. Each water inlet continuously sprays breeding water, and a water outlet is set on the bottom of the other end to make the breeding water body flow.

[0022] Preferably, the water inlet is in the shape of a rectangular hole.

[0023] In the above breeding method, the above-mentioned Huangshi Climbing Catfish breeding device can form a breeding water body for the Huangshi Climbing Catfish to live in, and form a relatively uniform water flow layer at the bottom of the breeding water body, thereby maximally imitating the water environment suitable for the natural life of the Huangshi Climbing Catfish and improving the breeding quality.

[0024] To sum up, the above-mentioned Huangshi climbing catfish breeding device and method can not only form a relatively uniform water flow at the bottom of the breeding water layer, but also control and adjust the water flow speed at the bottom of the breeding water layer, thereby maximally imitating the water environment suitable for the life of Huangshi climbing catfish and improving the breeding quality; in addition, the outlet pipe of the breeding box adopts an inverted U-shaped structure, which has both sewage discharge and water return functions. The design is ingenious, which makes sewage discharge easy and greatly reduces manpower consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following further describes the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0033] Example 1

[0034] Figure 1-5 The present invention shows a Huangshi climbing catfish breeding device. Figure 1As shown, the Huangshi climbing catfish breeding device includes a breeding box 1, and a partition 11 is provided inside the breeding box 1. The partition 11 separates the breeding box 1 into a water inlet bin 101 and a breeding bin 102. A plurality of water holes 12 are provided at intervals at the bottom end of the partition 11. A water outlet hole 13 is provided on the bottom surface of the breeding bin 102 away from the partition 11. The water inlet bin 101 is connected to a water inlet pipe 14.

[0035] The water in the water inlet tank 101 flows into the breeding tank 102 through multiple water holes 12. Since the water holes 12 and the water outlet holes 13 are both located at the bottom of the water flow in the breeding tank 102, a relatively stable flowing water body is generated at the bottom of the breeding water in the breeding tank 102, simulating the water environment suitable for the life of the Yellowstone catfish and improving the breeding quality.

[0036] Optionally, during aquaculture, the liquid level in the water inlet tank 101 is higher than that in the aquaculture tank 102. Under the influence of gravity, the water in the water inlet tank 101 automatically flows through the water flow holes 12 into the aquaculture tank 102 at a certain flow rate, creating a flowing water body at the bottom of the aquaculture water body. Furthermore, by adjusting the flow rate of the water inlet pipe 14, the difference in the liquid level between the water inlet tank 101 and the aquaculture tank 102 can be varied, achieving flow rate regulation at the water flow holes 12 within a small range.

[0037] Optionally, in order to increase the flow rate of the water flow at the water hole 12 and the adjustability of the flow rate, as shown in FIG. Figure 2 As shown, the top surface of the breeding chamber 102 is open, and the top surface of the water inlet chamber 101 is provided with a closed cover plate 15, forming a closed space within the water inlet chamber 101. A regulating valve 141 is provided on the water inlet pipe 14. The regulating valve 141 controls the flow rate of the water inlet pipe 14, changes the pressure of the water inlet chamber 101, and adjusts the water outlet speed of the water hole 12, thereby adjusting the water flow speed within the breeding chamber 102. This is flexible and easy to adjust to meet the water flow speed requirements of the Yellowstone catfish.

[0038] In addition, when the top of the water inlet bin 101 is closed by the closing cover 15, an exhaust valve can be set on the closing cover 15 of the water inlet bin 101. When water is initially added to the water inlet bin 101, the water hole 12 is blocked and the exhaust valve is opened so that a certain height of water can be injected into the water inlet bin 101; after the water filling is completed, the exhaust valve is closed to maintain the closed state.

[0039] Optionally, the aquaculture box 1 may be a rectangular parallelepiped structure, with dimensions of 900 mm * 450 mm * 300 mm. The aquaculture water depth is typically approximately 25 cm. According to aquaculture standards for recirculating aquaculture systems, a minimum biomass of 2 kg is acceptable. If the aquacultured organisms weigh 30 g, 66 can be cultured. If the aquacultured organisms are 5 cm long, based on ornamental fish farming experience, 20 can be cultured.

[0040] Optionally, the water holes 12 are evenly spaced along the length of the bottom end of the partition 11 to form a long fish comb structure. The interval and width of the water holes 12 of the fish comb are set to 1-5 mm, which can play a role in uniform water inflow and control flow rate.

[0041] Optionally, the water hole 12 is in the shape of a rectangular hole, and the long side and wide side of the water hole 12 are parallel to the long side and wide side of the breeding box 1 respectively. Compared with the round hole, the water flow out of the rectangular hole is more uniform and stable.

[0042] Optional, such as Figure 2 As shown, a water outlet pipe 16 is installed on one side of the culture tank 1. This inverted U-shape pipe 16 includes a first pipe section 161 and a second pipe section 162 spaced apart, and a third pipe section 163 connecting the first and second pipe sections 161 and 162. The first pipe section 161 is connected to the water outlet 13, and the second pipe section 162 is connected to the return pipe 17. An isolation net is installed at the water outlet 13 to prevent the yellow stone catfish from escaping the culture tank 102. The third pipe section 163 is horizontal and is set above the bottom surface of the culture tank 102 by a distance d. The value of d is determined by the living environment of the yellow stone catfish and is generally 20 to 40 cm.

[0043] The third pipe section 163 of the inverted U-shaped water outlet pipe 16 can effectively control the liquid level in the breeding bin 102. During design, the height of the third pipe section 163 relative to the bottom of the breeding bin 102 is designed according to the required liquid level, thereby ensuring that the breeding bin 102 always has a suitable capacity of breeding water.

[0044] Optionally, the middle of the first pipe section 161 is connected to the water outlet 13 pipeline, the bottom end of the first pipe section 161 is connected to the sewage pipe 19, and a sewage valve 18 is provided at the connection between the sewage pipe 19 and the first pipe section 161.

[0045] The middle part of the first pipe section 161 is connected to the water outlet 13, so that in the process of the water flowing out of the water outlet 13 flowing upward into the third pipe section 163 in the first pipe section 161, the impurities such as feces carried by it are precipitated into the lower pipe of the first pipe section 161. Then, during the breeding process, the sewage valve 18 can be opened regularly for convenient and quick cleaning, which is convenient for breeding management.

[0046] Optional, such as Figure 3-5 As shown, the Huangshi climbing catfish breeding device also includes a bracket 4, on which several rows of breeding boxes 1 are supported. Each row includes several breeding boxes 1 arranged vertically at intervals, and all breeding boxes 1 in each row share a water inlet pipe 14, a return pipe 17 and a sewage pipe 19.

[0047] Placing multiple breeding boxes 1 on the same bracket 4 saves space; and each row of vertical breeding boxes 1 shares a water inlet pipe 14, a return pipe 17 and a sewage pipe 19, effectively reducing equipment costs, facilitating breeding management, and improving breeding efficiency.

[0048] Optionally, six breeding boxes 1 are arranged on a single rack 4, with two boxes 1 secured on each floor. Each rack 4 layer is 50 cm high, with two racks 4 arranged in a horizontal row, 10 cm apart, for piping installation. Two rows of racks 4 are spaced 1 meter apart and placed in a container, with 50 cm between the sides, to form a single breeding workshop. The workshop is constructed from a converted container measuring 5.8 meters long, 2.9 meters wide, and 2.4 meters high.

[0049] Optionally, the Huangshi scaly fish farming apparatus further includes a circulating water pump 2 and a water treatment device 3. The pumping port of the circulating water pump 2 is connected to the outlet of the water treatment device 3, which in turn is connected to the water inlet pipe 14. The water inlet of the water treatment device 3 is connected to the outlet hole 13 via a pipeline. The farming water flowing out of the outlet hole 13 of the farming chamber 102 enters the water treatment device 3, where it undergoes filtration, sterilization, oxygenation, and / or cooling processes. The circulating water pump 2 then pumps the water back into the water inlet chamber 101 for recycling, thus conserving water.

[0050] Optionally, the circulating water pump 2 and the water treatment device 3 are arranged at the bottom layer of the bracket 4, and each row of breeding boxes 1 shares a set of circulating water pump 2 and water treatment device 3.

[0051] Optionally, the water treatment device 3 includes a filter tank, an aeration device and / or a water cooling device.

[0052] The filter tank can be a model CPA-75000 from Guangzhou Wilma Electromechanical Co., Ltd. The working principle of the filter tank is as follows: water entering the filter tank first passes through coarse and fine filter cotton to filter out impurities, which can be discharged through the sewage outlet. Then, nitrifying bacteria cultivated on the biochemical cotton decompose feces and harmful substances. After that, ultraviolet light is used to inhibit pathogens in the water. Finally, clean filtered water flows out.

[0053] The aeration device is used to add oxygen to the return water, including an oxygen machine and an oxygen gas disk, which continuously aerates the water flow, increases the contact area between the circulating water and the atmosphere, and increases the dissolved oxygen content.

[0054] The water cooling device includes: a chiller, a pipe-type heat exchanger and a temperature sensor. Since the growth environment of the Yellowstone catfish requires low-temperature water flow, the returning aquaculture water needs to be kept at a relatively low temperature. By setting a temperature sensor in the aquaculture bin 102 to monitor the water temperature, the chiller can provide cooling water for the pipe-type heat exchanger, and the water flowing out of the outlet pipe 16 flows through the pipe of the pipe-type heat exchanger. When the temperature sensor detects that the temperature of the aquaculture bin 102 is higher than the set value, the set value is usually 10 to 18°C, the chiller is started to cool the circulating aquaculture water flowing through the pipe-type heat exchanger to the set value, preferably 15°C, to achieve cooling of the aquaculture water and continuously keep the circulating water at a low temperature.

[0055] Optionally, the water inlet of the water treatment device 3 is also connected to a water supply system for providing raw water for aquaculture. This water supply system provides a source of water for aquaculture and allows for timely replenishment of water when water loss occurs during the circulation process. A liquid level sensor can be installed in the aquaculture tank 102. When the liquid level falls below a set value, the water supply system is automatically activated to add raw water from the water inlet of the water treatment device 3.

[0056] The entire aquaculture water usage process is as follows:

[0057] First, open the water supply system, close the drain valve 18 and water outlet 13, seal the water hole 12, and inject raw aquaculture water into the water treatment device 3 through the pipeline. After the raw water is cooled, filtered, sterilized, and / or oxygenated, the circulating water pump 2 continuously injects aquaculture water into the water inlet tank 101 through the water inlet pipe 14, so that the water level in the water inlet tank 101 reaches a certain level. Note that when the top of the water inlet tank 101 is closed by the cover plate 15, the exhaust valve needs to be opened for the initial water addition and closed after the water filling is completed.

[0058] Next, the water hole 12 is opened, and aquaculture water is injected into the aquaculture bin 102 through the water hole 12. When the water reaches a certain height higher than the third pipe section 163 of the U-shaped outlet pipe 16, an aquaculture water body is formed.

[0059] Then, the water outlet 13 is opened to allow the aquaculture water to continuously flow out of the water outlet 13 and circulate through the water treatment device 3 and the water inlet tank 101 through the action of the circulating water pump 2 for recycling.

[0060] Finally, the Yellowstone trout breeding population is placed in the breeding warehouse 102. In addition, during use, the drain valve 18 needs to be opened regularly, and the larger excrement and other impurities of the precipitation are discharged from the drain pipe 19. The filtering equipment of the water treatment filter is regularly cleaned to ensure filtering efficiency.

[0061] This aquaculture device maintains a low-temperature aquaculture environment while maintaining water flow at the bottom of the aquaculture layer. It also controls the water flow rate, minimizing the aquatic environment suitable for the Yellowstone catfish and preventing environmental damage during the aquaculture process. The device's outlet piping cleverly combines wastewater discharge and return water, facilitating wastewater discharge, significantly reducing labor consumption, and significantly conserving aquaculture water.

[0062] The present invention provides a method for using the aforementioned Huangshi climbing catfish aquaculture device, comprising the following steps: establishing an aquaculture water body with a water depth of 15 to 25 cm and a water temperature of 10 to 18°C within an aquaculture box 1; providing a row of water inlets at the bottom of one end of the aquaculture water body, each of which continuously sprays aquaculture water; and providing a water outlet on the bottom of the other end to keep the aquaculture water body in a flowing state. This enables a relatively uniform water flow to be formed at the bottom of the aquaculture water layer, thereby improving aquaculture quality.

[0063] Optionally, the water inlet is in the shape of a rectangular hole.

[0064] 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 its scope of protection. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that after reading the present invention, those skilled in the art may still make various changes, modifications or equivalent substitutions to the specific implementation methods of the invention, but these changes, modifications or equivalent substitutions are all within the scope of protection of the pending claims of the invention.
