Description

A land-based sea cucumber culture pond and a sea cucumber culture method Technical Field

[0001] This invention relates to a land-based aquaculture pond, and more particularly to a land-based aquaculture pond for sea cucumbers. Background Technology

[0002] Sea cucumber is currently the most valuable single-species economic animal in my country's marine aquaculture industry. Land-based pond aquaculture is the main production mode for my country's sea cucumber industry. However, due to the impact of global climate change, frequent high-temperature periods in summer have significantly affected land-based pond aquaculture, causing serious economic losses.

[0003] It is reported that the optimal growth temperature for sea cucumbers is 8-15℃. Above 20℃, they enter a state of summer dormancy, and the maximum water temperature for cultivation should not exceed 30℃, with an extreme tolerance temperature of 33℃. However, since 2013, the bottom temperature of ponds in northern my country during the summer high-temperature period has reached 33-34℃, exceeding the temperature tolerance limit of sea cucumbers, resulting in a mortality rate of over 50%, and in some years even reaching 90%. Therefore, how to effectively reduce the bottom water temperature and sea cucumber mortality is the most pressing issue for farmers. Currently, to cope with the high-temperature sea cucumber farming environment, some farmers choose to build sunshades on top of land-based farming ponds. However, this only achieves partial surface coverage for some small sea cucumber farming ponds; areas not covered by sunshades are still affected by high temperatures. This method is not only slow in reducing the pond bottom temperature but also difficult to operate and manage. Therefore, these problems need to be solved. Summary of the Invention

[0004] This invention provides a land-based sea cucumber culture pond and a sea cucumber culture method, which solves the problem of how to lower the bottom water temperature of the land-based sea cucumber culture pond, thereby improving the survival rate of sea cucumbers during summer dormancy.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: a sea cucumber land-based culture pond, comprising: placed within the land-based culture pond:

[0006] Several aquaculture units, each of the aquaculture units including a net reef and a pond near the net reef for aquaculture of sea cucumbers;

[0007] The heat exchange pipes include a third pipe laid near the aquaculture unit and cold water in the third pipe. The cold water flowing through the heat exchange pipes reduces the temperature of the pool water near the reef by 2-5°C.

[0008] As a further improvement, the positional relationship between the third pipeline and the reef includes one or both of the following:

[0009] 1) The third pipeline passes through the inside of the reef, and the surface of the third pipeline is in contact with the bottom surface of the reef.

[0010] 2) The third pipeline is laid between the bottom of the reef and the bottom of the land-based aquaculture pond, and the surface of the third pipeline is in contact with the outer surface of the bottom of the reef.

[0011] As a further improvement, it also includes a liquid storage unit for storing cold water, the outlet of the liquid storage unit being connected to the inlet of a third pipe through a first pipe, the outlet of the third pipe being drained through a second pipe, and a water pump being installed on the first or second pipe.

[0012] As a further improvement, the third pipeline is formed by the body itself forming a first passage that runs through both ends. The liquid storage unit is connected to the inlet of the first passage through the first pipeline, and the outlet of the first passage drains water through the second pipeline. A water pump is installed on the first pipeline or the second pipeline.

[0013] As a further improvement, the storage unit is a cold water well.

[0014] As a further improvement, the liquid storage unit is a tank-shaped container, and the first pipeline is connected to the bottom of the liquid storage unit.

[0015] As a further improvement, a refrigeration unit is also included. The liquid storage unit is provided with left and right water inlets and a return port at its upper part. The refrigeration unit is installed on the second pipeline, and the second pipeline is connected to the return port.

[0016] As a further improvement, the top and bottom surfaces of the body are integrally formed with an upper protrusion structure and a lower protrusion structure, respectively. There is a gap between adjacent upper and lower protrusion structures. A second passage is formed inside the upper and lower protrusion structures, penetrating both ends of them. The two ends of the second passage are connected to the first pipe and the second pipe, respectively.

[0017] As a further improvement, a first connector and a second connector are respectively fixedly provided on the side wall surfaces of two adjacent bodies, and the ends of the first connector and the second connector away from the body can be disconnected.

[0018] To achieve the above objectives, the technical solution of the present invention is: a method for cultivating sea cucumber, comprising cultivating sea cucumber using the above-mentioned land-based sea cucumber cultivation pond.

[0019] The above-described technical solution of the present invention has the following beneficial effects:

[0020] 1. When the temperature at the bottom of the land-based aquaculture pond is too high and temperature regulation is required, the water pump is turned on, so that the water in the storage unit enters the third pipe along the first pipe. The water will exchange heat at the bottom of the land-based aquaculture pond in the third pipe, thereby regulating the temperature at the bottom of the land-based aquaculture pond. After heat exchange, the water flows out from the third pipe and enters the second pipe for discharge. The third pipe is arranged in parallel inside the bottom surface of the land-based aquaculture pond, so that the water can pass through quickly and complete the heat exchange, thereby quickly achieving temperature regulation.

[0021] 2. The integrated molding of the main body with the upper and lower protruding structures enhances structural stability. After the main body is installed inside the land-based aquaculture pond, the end of the lower protruding structure furthest from the main body contacts the bottom surface of the pond. Due to the spacing between adjacent upper and lower protruding structures, water flows through these spaces. A second passageway is formed within the upper and lower protruding structures, increasing the contact area between the main body and the water. This allows for faster temperature regulation of the bottom surface and water in the land-based aquaculture pond. The bottom of the pond has fine mud and sand, and the raised structure can be further inserted into the fine mud and sand. This eliminates the need to use heavy objects such as stones or woven bags filled with sand to press down and fix the body. It is convenient to use during actual installation, ensures that the body does not shake, and after the cold water flows in the first and second channels, the temperature of the fine mud and sand at the bottom of the land-based aquaculture pond will be further reduced. This further reduces the water temperature at the bottom of the entire land-based aquaculture pond rapidly and uniformly in all areas, ensuring the survival environment of algae, various plankton, and microorganisms at the bottom of the land-based aquaculture pond, thereby improving the survival rate of sea cucumbers.

[0031] The following embodiments further illustrate the content of the present invention, but should not be construed as limiting the present invention. Any modifications or substitutions made to the methods, steps, or conditions of the present invention without departing from the spirit and essence of the invention are within the scope of the present invention.

[0032] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings and examples.

[0033] Example 1

[0034] Please refer to Figures 1 to 3. This invention discloses a sea cucumber land-based aquaculture pond, comprising: several aquaculture units, each including a net reef 13 and pond water near the net reef 13 for sea cucumber cultivation; and several heat exchange pipes, including a third pipe 2 laid near the aquaculture units and cold water within the third pipe 2. The cold water flowing through the heat exchange pipes lowers the temperature of the pond water near the net reef 13 by 2-5°C, preferably 2-3°C. The sea cucumber land-based aquaculture pond of this application has a net reef 13 set at the bottom of the land-based aquaculture pond, where sea cucumbers inhabit the net reef 13. For sea cucumber cultivation, when the reef 13 is placed at the bottom of the land-based aquaculture pond, the water from the land-based aquaculture pond enters the reef 13 through the mesh due to the reef 13's mesh structure. A third pipeline is laid in the vicinity of the reef 13. It should be noted that the aquaculture unit includes the reef 13 and the water in the vicinity where sea cucumbers are cultivated. The water in the vicinity of the reef 13 includes the water in contact with the surface of the reef 13 and the water that permeates into the interior of the reef 13. Heat exchange is achieved through the cold water flowing in the third pipeline 2, thereby lowering the water temperature at the bottom of the land-based aquaculture pond and inside the reef 13 near the bottom of the land-based aquaculture pond. At 2-5℃, the temperature of the pond water in contact with the sea cucumber decreases. The land-based aquaculture pond of this application increases the survival rate of sea cucumbers during the summer by more than 30%. It should be further noted that the aquaculture unit can also be other devices providing habitat for the sea cucumbers, such as net troughs or net cages, preferably net reefs 13. Net reefs 13 are multiple interconnected cage-like structures woven from thread. The lengths of the net reefs 13 can be the same or different. To place several aquaculture units parallel to each other at the bottom of the land-based aquaculture pond 3, the interval between each aquaculture unit is 3.5m-4.5m, preferably 4m. The third pipeline can be... For horticultural drip irrigation, the length of the third pipe can be the same as the length of the reef 13, or the length of the third pipe 2 can be the same as the length of the bottom surface of the land-based aquaculture pond. The third pipe 2 can be laid below the reef 13, with the bottom surface of the third pipe 2 in contact with the bottom surface of the land-based aquaculture pond 3. Alternatively, the third pipe 2 can be laid on both sides of each reef 13, with one side wall of the third pipe 2 in contact with one side outer surface of the reef 13. Or, the third pipe 2 can be laid at the bottom of the land-based aquaculture pond, with the outer surface of the intersection of the third pipe 2 and the reef 13 in contact with each other. The diameter of the third pipe 2 can be 1-2 inches, preferably 1 inch.The cold water source can be a reservoir, a cold water well, or a storage tank. Since sea cucumber farming is located along the coast, and there are numerous cold water wells near the sea, natural resources can be fully utilized, reducing costs. The storage tank is a tank-shaped structure for storing cold water. A third pipeline is connected to one end of the reservoir, cold water well, or storage tank. A water pump circulates the cold water within the third pipeline and eventually discharges it, lowering the water temperature in the reef 13 by 2-5°C, thus reducing the mortality rate of sea cucumbers caused by high temperatures. This application also includes a temperature measuring device, including a temperature sensor and a temperature display. The sensor and display are electrically connected. The temperature sensor is placed at the bottom of the land-based aquaculture pond 3. When the display shows that the bottom of the land-based aquaculture pond 3 reaches 30°C, the water pump is turned on to cool the water at the bottom of the pond through the third pipeline.

[0035] Example 2

[0036] Referring to Figures 1 to 3, based on the technical solution of Embodiment 1, the positional relationship between the third pipeline 2 and the reef 13 includes any one or a combination of the following:

[0037] 1) The third pipe 2 passes through the inside of the reef 13, and the surface of the third pipe 2 is in contact with the bottom surface of the reef 13, which lowers the water temperature near the sea cucumber and improves the survival rate of the sea cucumber.

[0038] 2) The third pipeline 2 is laid between the bottom of the net reef 13 and the bottom surface of the land-based aquaculture pond 3. The surface of the third pipeline 2 is in contact with the outer surface of the bottom of the net reef 13, which makes the temperature of the pond water inside the net reef 13 drop faster and further improves the survival rate of sea cucumbers.

[0039] Example 3

[0040] Referring to Figures 1 to 3, based on the technical solution of Embodiment 1, several third pipes 2 are laid on the bottom surface of the land-based aquaculture pond 3. The outer surfaces of the third pipes 2 and the reef 13 at their intersections are in contact with each other. The intersecting third pipes 2 and the reef 13 cover the bottom surface of the land-based aquaculture pond 3 between the reef 13. Since sea cucumbers feed on algae, various debris, microorganisms, etc. at the bottom of the land-based aquaculture pond 3, excessively high temperatures will reduce the abundance of various foods consumed by sea cucumbers, affecting their growth and survival. Therefore, this method of laying third pipes can not only reduce the temperature of the water in the reef 13 quickly, but also reduce the water temperature at the bottom of the entire land-based aquaculture pond 3 rapidly, ensuring the abundance of food at the bottom of the land-based aquaculture pond 3, thereby improving the survival rate of sea cucumbers. Experiments show that when the overall water temperature at the bottom of the land-based aquaculture pond 3 decreases by 2-3℃, planktonic microorganisms become more active, further improving the survival rate of sea cucumbers.

[0041] Example 4

[0042] Referring to Figures 1 to 3, based on the technical solution of Embodiment 1, the present invention discloses a sea cucumber land-based aquaculture pond, which further includes a storage unit for storing cold water. The outlet of the storage unit is connected to the inlet of the third pipe 2 through a first pipe 4. The outlet of the third pipe 2 drains water through a second pipe 5. A water pump 6 is installed on the first pipe 4 or the second pipe 5. In the land-based aquaculture pond of this application, the third pipe 2 is laid on the bottom surface of the land-based aquaculture pond 3. The two ends of the third pipe 2 are connected to the first pipe 4 and the second pipe 5, respectively. The storage unit 1 is used for storing cold water. When the bottom temperature of the land-based aquaculture pond 3 reaches 30°C, the water pump 6 is turned on, so that the water in the storage unit 1 enters the third pipe 2 along the first pipe 4. The cold water exchanges heat with the bottom of the land-based aquaculture pond 3 in the third pipe 2, thereby reducing the temperature of the bottom of the land-based aquaculture pond 3. The water that has undergone heat exchange flows out from the third pipe 2 and is discharged into the second pipe. The number of storage units 1 can be set according to actual needs.

[0043] Example 5

[0044] Please refer to Figures 1 to 3. Based on the technical solution of Embodiment 1, and as shown in Figures 5 to 7, the third pipeline 2 is formed by a first passage 8 extending through both ends of the main body 7. The liquid storage unit 1 is connected to the inlet of the first passage 8 via the first pipeline 4. The outlet of the first passage 8 drains water through the second pipeline 5. A water pump 6 is installed on the first pipeline 4 or the second pipeline 5. In the land-based aquaculture pond 3 of this application, the main body 7 is installed on the bottom surface inside the land-based aquaculture pond 3, and the first pipeline 4 and the second pipeline 5 are connected to the first passage 8. The second pipe 5 is connected to the first passage 8, so that both ends of the first passage 8 are connected to the first pipe 4 and the second pipe 5 respectively. The storage unit 1 is used for storing cold water. When the bottom temperature of the land-based aquaculture pond 3 reaches 30°C, the water pump 6 is turned on, so that the water in the storage unit 1 enters the first passage 8 along the first pipe 4. The water in the first passage 8 exchanges heat with the bottom of the land-based aquaculture pond 3, thereby regulating the temperature of the water at the bottom surface and bottom position of the land-based aquaculture pond 3. The water that has undergone heat exchange flows out from the first passage 8 and enters the second pipe 5 for discharge. The number of units 1 can be set according to actual needs. The body 7 can be a plate-like structure. The body 7 has a first passage 8 that runs through both ends. There can be one or more first passages 8. When there is one first passage 8, the body 7 is hollow. Cold water automatically flows into the body 7 along the first pipe 4 for storage. When the bottom of the land-based aquaculture pond 3 starts to heat up, the large amount of water stored in the body 7 will first absorb heat from the bottom of the land-based aquaculture pond 3. When the temperature continues to rise to 30°C, the water pump 6 will be started, and the water will flow to further exchange heat and achieve temperature regulation. Alternatively, multiple first passages 8 can be formed inside the body 7 to further achieve heat exchange and achieve temperature regulation. The above scheme can also be further improved by: several through holes 14 are opened vertically from the surface of the body 7 to the inside of the first passage 8. The through holes 14 are connected to the inside of the first passage 8. When the water pump 6 is turned on, the cold water in the first passage 8 can seep out through the through holes 14 to achieve faster cooling of the bottom of the land-based aquaculture pond 3 and especially the pond water near the reef 13.

[0045] Example 6

[0046] Referring to Figures 1 to 3, based on the technical solution of Embodiment 1, a further solution could be that the liquid storage unit 1 is a cold water well (not shown in the figure). The cold water well could contain groundwater or be a cold water well commonly found along the coast. During the high-temperature period in summer, heat exchange is used to lower the temperature of the water around the sea cucumber by 3-4°C during sea cucumber farming, thereby improving the survival rate of sea cucumbers during the high-temperature period in summer. When using a cold water well commonly found along the coast, the end of the second pipeline away from the third pipeline can be connected to another cold water well. In this way, when the water pump 6 is started, water circulation is activated, and the water discharged from the second pipeline 5 is recycled for reuse, thus recycling resources, reducing resource waste, making full use of natural resources, eliminating the need for refrigerants, and reducing energy consumption.

[0047] Example 7

[0048] Please refer to Figures 1 to 3. Based on the technical solution of Embodiment 1, and please refer to Figure 4, the liquid storage unit 1 is a tank-shaped container. The first pipeline 4 is connected to the bottom of the liquid storage unit 1. Cold water is stored in the tank-shaped container. The cold water enters the first pipeline 4 more quickly under the assistance of gravity to achieve heat exchange.

[0049] Example 8

[0050] Referring to Figures 1 to 3, based on the technical solution of Embodiment 7, and referring to Figure 4, it further includes a refrigeration unit 9. The upper part of the liquid storage unit 1 is provided with left and right water inlets and a return port. The refrigeration unit 9 is installed on the second pipeline 5, which is connected to the return port. The refrigeration unit 9 is used to cool the circulating water and then return it. When the water pump 6 is started, the water circulation is activated, and the water discharged from the second pipeline 5 is recycled for reuse, thus recycling resources and reducing waste.

[0051] Example 9

[0052] Referring to Figures 1 to 3, based on the technical solution of Embodiment 5, and referring to Figure 7, the top and bottom surfaces of the body 7 are integrally formed with an upper protrusion structure 10 and a lower protrusion structure 11, respectively. Adjacent upper protrusion structures 10 and lower protrusion structures 11 are spaced apart. A second passage 12 is formed inside each of the upper and lower protrusion structures 10 and 11, penetrating both ends. The two ends of the second passage 12 are respectively connected to a first pipe 4 and a second pipe 5. The body 7 is connected to the upper protrusion structure 10 and the lower protrusion structure 11. The integral molding of the protruding structures 11 makes the structure more stable. After the main body 7 is installed inside the land-based aquaculture pond 3, the end of the lower protruding structure 11 away from the main body 7 contacts the bottom surface of the land-based aquaculture pond 3. Since there is a gap between the adjacent upper protruding structures 10 and lower protruding structures 11, the gap allows water to flow in the land-based aquaculture pond 3. A second passage 12 is formed inside the upper protruding structure 10 and lower protruding structure 11, which runs through both ends, increasing the contact area between the main body 7 and the water, and at the same time, achieving faster water flow to the bottom surface of the land-based aquaculture pond 3. The temperature of the water at the bottom of the land-based aquaculture pond 3 is regulated. Since the bottom of the land-based aquaculture pond 3 has fine silt, the protruding structure can be further inserted into the fine silt. This eliminates the need to use stones or woven bags filled with sand to weigh down and fix the main body, making it convenient to use during actual installation and ensuring the main body does not shake. Furthermore, after the cold water flows in the first passage 8 and the second passage 12, the temperature of the fine silt at the bottom of the land-based aquaculture pond 3 will further decrease, further causing the water temperature at the bottom of the entire land-based aquaculture pond 3 to drop rapidly and in different areas. The uniform temperature of the area ensures the survival environment of algae, various plankton, microorganisms, etc. at the bottom of the land-based aquaculture pond 3, thereby improving the survival rate of sea cucumbers. The above scheme can be further improved by: several through holes 14 are vertically opened from the surface of the upper protruding structure 10 into the interior of the second passage 12, and the through holes 14 are connected to the interior of the second passage 12. When the water pump 6 is turned on, the cold water in the second passage 12 can seep out through the through holes 14, so as to achieve faster cooling of the pond water at the bottom of the land-based aquaculture pond 3 and especially near the reef 13.

[0053] Example 10

[0054] Referring to Figures 1 to 3, based on the technical solution of Embodiment 9, and referring to Figure 8, a first connector 19 and a second connector 20 are respectively fixedly disposed on the sidewall surfaces of two adjacent bodies 7. The ends of the first connector 19 and the second connector 20 away from the body 7 are detachably connected, and the bodies 7 are detachably connected. This allows the number of bodies 7 to be adjusted according to the size of the land-based aquaculture pond 3 and the area requiring temperature regulation. The first connector 19 and the second connector 20 have the same shape. The first connector 19 includes a base 22, a connecting part 23, and a fixing part 24 that are fixedly connected in sequence. The base 22, the connecting part 23, and the fixing part 24 are all rectangular block structures. The end of the base 22 away from the connecting part 23 is fixedly connected to the outer surface of two adjacent bodies 7. The connecting part 23 is perpendicular to the base 22 and the fixing part 24, and the base 22 is parallel to the fixing part 24. The length of the base 22 is greater than the length of the fixing part 24. The distance between the end of the fixing part 24 away from the connecting part 23 and the surface of the connected body 7 is the same as the width of the connecting plate. When two adjacent bodies 7 are spliced ​​together, the two bodies 7 are first staggered so that the positions of the first connecting piece 19 and the second connecting piece 20 correspond. The connecting part 23 passes through the distance between the end of the fixing part 24 away from the connecting part 23 and the surface of the connected body 7, and the first connecting piece 19 and the second connecting piece are spliced ​​together. At this time, the two fixing parts and the two connecting parts 23 are located between the two bases 22. The distance between the two adjacent bodies 7 is the same as the width of the base 22. Splicing in this way makes the connection of the first connecting piece 19 and the second connecting piece 20 more stable, and the connection structure is simple and convenient, making it easy to assemble and disassemble. At the same time, it prevents multiple bodies 7 from shaking due to the flow of water during temperature adjustment.

[0055] The present invention discloses a method for cultivating sea cucumbers, including cultivating sea cucumbers using the above-mentioned land-based sea cucumber cultivation pond;

[0056] Further methods include the following:

[0057] 1) Increase water depth and reduce transparency: During the high-temperature period, raise the water level to 2-2.5m, add appropriate bacteria, and cultivate a lush and vibrant water color. At the same time, combine with swirls or use chemical light-blocking agents (such as chloroform, sodium humate, etc.) to reduce light intensity.

[0058] 2) Install oxygenation equipment: Add waterwheel-type aerators to the aquaculture ponds. Turn them on at night when the air temperature is lower than the water temperature. This can effectively break up water stratification, ensure sufficient dissolved oxygen in the water, and at the same time, it can dissipate heat and lower the water temperature.

[0059] 3) Remove excess aquatic plants from the bottom of the pond to prevent oxygen depletion and heat generation caused by the death and decay of the plants.

[0060] 4) Water conditioning and bottom improvement: Regularly use water conditioning and bottom improvement products to prevent the "red water" phenomenon caused by excessive algae growth, monotonous algae composition, and acute algal bloom collapse during the high-temperature season.

[0079] Compare with Example 1

[0080] Comparative Example 1 is a method for cultivating sea cucumbers, which differs from the embodiment in that the land-based sea cucumber cultivation pond of this application is not used.

[0081] Experimental Example 1: Survival Rate Test of Sea Cucumber during High Temperature Period

[0082] 3000 sea cucumber seedlings (30-50 heads / catties) were cultured according to the methods of Examples 11-13 and Comparative Example 1, respectively. The sea cucumber seedlings were purchased from Tangshan Caofeidian District Fengying Aquaculture Co., Ltd. The sea cucumbers in Examples 11-13 and Comparative Example 1 were cultured in a 1-acre enclosure. The survival rates of the sea cucumbers after the summer high-temperature period are shown in the table below:

[0083] Group Experiment Quantity Outdoor Maximum Air Temperature / Maximum Water Temperature Number of Fish Catch Survival Rate

[0084] Example 1: 1300037℃ / 30℃ 235078.3%

[0085] Example 1: 2300037℃ / 30℃ 239679.9%

[0086] Example 1: 3300037℃ / 29℃ 246882.3%

[0087] Comparison Example 1: 3000℃ / 33℃ = 104634.9%

[0088] According to the experimental results, the survival rate of sea cucumbers cultured using the culture methods of Examples 11-13 was 43%-47% higher than that of sea cucumbers cultured using the culture method of Control Example 1. Based on the experimental comparison results, the survival rate of sea cucumbers cultured using the culture method of Example 13 after surviving the high temperature period in summer was higher than that of Control Example 1 and other examples. In other words, using the sea cucumber culture pond of this application for sea cucumber culture can effectively improve the survival rate of sea cucumbers during the high temperature period in summer.

[0089] The above-described embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
