Description

Technical Field

[0001] The present invention relates to a breeding frame, which is used for breeding mollusks, fish, seaweed and the like including high value-added aquatic products, namely sea cucumbers, abalones, other shellfish or octopuses, and more specifically, to a stepped multi-layer breeding frame and a setting method thereof, which is a stepped or pyramidal (inclined) structure with a wider area toward the bottom and provides multi-layer breeding space to improve production efficiency, and improves construction efficiency by adding connection technology. Background Art

[0002] The content in this section only provides background information related to the content of this application and is not necessarily prior art.

[0003] Most of the existing sea cucumber or abalone farming techniques are to set up independent habitats in the form of small-scale artificial structures or evenly paving rocks or piling stones on the bottom of the water, and then spread seedlings (about 1 to 5 cm), and harvesting depends on underwater work by divers, etc., so it is actually impossible to harvest aquatic products that live deep in the rocks. In addition, the sea cucumber farming in the cage frame of the seawater cage farm is a single-layer farming structure, so the farming quantity and output are very limited, and because it is in contact with the seawater surface, it is a structure that is vulnerable to high seawater temperatures in summer and frost damage in winter.

[0004] In addition, sea cucumbers and abalones cultured in indoor tanks on land are mainly cultured in tanks. The culture structure of sea cucumbers is a single-layer form, so the output is limited. Although the culture structure of abalone uses corrugated plates to increase the culture volume, the output is also limited.

[0005] In recent years, the feasibility of feeding sea cucumbers with abalone excrement has been confirmed, so there is an urgent need to introduce a mixed culture device for abalone and sea cucumbers. It is very necessary for fishermen to introduce a stepped multi-layer culture frame that can eliminate the overcrowding caused by high-density breeding required to increase production in land tank farming or inland waters, facilitate management such as supplying food, and shorten the breeding and harvesting cycle. Summary of the invention

[0006] Problems to be solved by the invention

[0007] The present invention is proposed to solve the above-mentioned problems, and its purpose is to provide a stepped multi-layer breeding frame and a setting method thereof, wherein the stepped multi-layer breeding frame forms a breeding space in a multi-layer form, so that a high harvest can be obtained in a narrow area, and the breeding surface is formed in an inclined or stepped manner, so that stability can be provided, and at the same time, food is gathered at the edge of each layer to easily supply food, and the breeding environment is improved by dividing the breeding space and the food supply space. The setting method can not only use the breeding frame alone, but also continuously connect and set more than two breeding frames in one direction.

[0008] Methods used to solve problems

[0009] The stepped multi-layer farming frame according to the present invention is characterized in that the stepped multi-layer farming frame comprises: a farming frame body, which is a three-dimensional shape with an open periphery, and includes a farming surface that gradually widens from the upper part to the lower part or widens in a stepped manner on one or more sides; a porous and multi-layer farming layer, which is formed in a multi-level form inside the farming frame body and provides a farming space on its upper and lower surfaces, and has holes for allowing water to flow up and down; and a non-porous food supply part, which is formed at the edge of the farming surface of the farming frame body so as to be connected to the farming layer and prevent the food scattered from the upper part from falling to the lower layer and gathering.

[0010] The present invention is characterized in that the continuous connection setting method can not only use the breeding frame alone, but also can continuously set more than two breeding frames along one direction.

[0011] Effects of the Invention

[0012] The stepped multi-layer aquaculture frame and the setting method thereof according to the present invention have the following effects: the production efficiency is improved by setting the aquaculture space into multiple layers, and a large amount of aquatic products can be cultured even in a narrow area through the vertical structure, especially when used in a land tank type, high profits can be obtained while reducing costs, and different types of aquatic products can be cultured in different layers, so that stable income can be guaranteed through diversity, and a small number of people can be invested in management to reduce labor costs, thereby improving profit margins and maximizing high profit effects.

[0013] Moreover, it has the following effects: the structural characteristics of the breeding frame can concentrate the food around each breeding layer to reduce the amount lost to the outside of the breeding frame, thereby reducing cost losses, and the production efficiency can be improved through a stable food supply.

[0014] Not only can the breeding frame be used alone, but more than two breeding frames can also be continuously arranged in one direction, thereby being able to reduce costs during arrangement and harvesting.

[0015] In addition, in order to form a seaweed (seaweed) forest that has a very strong effect in absorbing carbon, the culprit of greenhouse gases caused by the global greenhouse effect due to excessive carbon emissions, seaweed (seaweed) spores are applied to the cultivation frame, and underwater carbon sinks that utilize blue carbon functions are actively formed. This is expected to make a certain contribution to the problem of global warming.

[0016] At the same time, the aquaculture technology of the present invention can be used in various aquaculture methods such as underwater setting, hanging, cage, land tank, celebration, inland aquaculture, etc., and can be selectively used by fishermen according to their needs. In particular, in the case of sea cucumber aquaculture, as a promising aquatic product, if sea cucumber aquaculture is popularized through the aquaculture technology of the present invention, it will help increase the income of fishermen and also bring benefits from the national perspective.

[0043] When describing the present invention below, if it is judged that the detailed description of the known functions or structures related to the present invention confuses the main purpose of the present invention, the detailed description will be omitted. In addition, the terms described below are defined according to the functions in the present invention, and the terms may vary according to the intention or convention of the user or operator. Therefore, the definition should be determined based on the content of the entire specification.

[0044] <1. Farming framework main body 10>

[0045] like Figures 1 to 3 As shown, the basic structure of the stepped multi-layer farming frame 100 according to the present invention is as follows: a farming frame body 10, which is a three-dimensional shape, and has a farming surface 11 that becomes wider toward the bottom on one or more sides; a porous farming layer 20, which is formed in a multi-level (multi-layer) form on the farming frame body 10; and a food supply part 30, which is formed on the farming surface 11 of the farming frame body 10 and is used to concentrate food.

[0046] The aquaculture frame body 10 provides multiple layers of aquaculture space, supplies food to aquatic products (sea cucumbers, abalones and other aquatic organisms) cultured in the aquaculture space of each layer, and includes, for example, a tilted ( Figure 1 and Figure 2 ), Stepped( Figure 3 ) has a breeding surface 11, wherein the breeding surface is a shape in which the area widens from the top to the bottom in order to form a food space (food supply portion 30) at the edge while forming a breeding space (breeding layer 20) inside.

[0047] The breeding frame body 10 is three-dimensional, and the inclined (stepped) breeding surface 11 is formed with more than one side. Figures 1 to 3 The figure shows an example of a truncated quadrangular pyramid (a pyramid shape with a flat upper portion and a quadrangular bottom and four inclined breeding surfaces 11) in which all four surfaces except the bottom surface are breeding surfaces 11. Figure 4 is a diagram illustrating an example of a farm having four stepped farming surfaces 11, Figure 5 1 is a diagram illustrating an example of a stepped (or inclined) farming surface 11. Figure 6 is a top view showing an example of having two breeding surfaces 11, Figure 7 is a top view showing an example having three breeding surfaces 11, Figure 8 This is an example of an upper hemispherical shape that is circular when viewed from above. Fig. 9 This is an example diagram of a semicircle when viewed from above.

[0048] The aquaculture frame body 10 is a skeleton capable of fixing the aquaculture layer 20 and the food supply part 30 and maintaining their shape. It is a structure with an open periphery. That is, the aquaculture layer 20 and the food supply part 30 are separated by a certain space and combined into multiple layers, thereby forming a space for aquaculture water (including seawater from the sea and seawater from land farms) to flow between the upper and lower adjacent aquaculture layers 20 and food supply parts 30.

[0049] For example, the skeleton is a shape in which four racks are combined into a rectangular frame to form a bottom, the racks are erected obliquely at the four corners of the bottom, and the heads (upper parts) of the racks are connected to rectangular or circular plates of different sizes. The racks can be made of various materials such as metal, concrete, synthetic resins, wood, FRP (fiber reinforced composite material), GFRP (glass fiber reinforced plastic), etc.

[0050] The farming frame body 10 may be a large structure, and thus may be transported and set up using a crane, and may include a lifting ring 12 for connection with the crane.

[0051] Preferably, the bottom of the aquaculture frame body 10 includes legs to separate the lowest aquaculture layer 20 from the seabed or the ground, thereby preventing the aquaculture frame body 10 from tilting due to uneven road surfaces. At the same time, it is also fixed to the seabed using anchors, stakes, etc., so as to prevent it from moving or losing due to seawater when it is set at sea.

[0052] As a technology for confirming the position of the stepped multi-layered aquaculture frame 100 and monitoring the aquaculture environment, various technologies can be applied, for example, a position detection device 13 can be included, which has the following functions: when the stepped multi-layered aquaculture frame 100 fails to maintain the setting state on the seabed and is lost, the stepped multi-layered aquaculture frame 100 can be found and recovered by the position detection device, and if necessary, the position of the aquaculture frame can be grasped by the position detection device and then food is sprinkled from the sea surface. The position detection device 13 includes an acoustic wave sensor including ultrasonic wave, GPS mode, radar mode, echo sounder, multi-beam, etc., and the position detection device 13 is set at the upper position of the aquaculture frame body 10 that does not interfere with aquaculture, and the management personnel can determine the position of the stepped multi-layered aquaculture frame 100 by confirming the signal. In addition, it can also be a buoy connected to the aquaculture frame body 10 and capable of floating on the water surface (it is a floating object floating on the water surface, which can confirm the position of the stepped multi-layered aquaculture frame 100).

[0053] In addition, an underwater camera for monitoring the stepped multi-layer farming frame 100 and the farming environment around it may also be included.

[0054] <2. Multi-layered culture layer 20>

[0055] The breeding layer 20 provides a space for aquatic life and is made of a porous component with multiple holes so that the breeding water can flow up and down, and the size of the holes in each layer can be different. For example, the breeding layer 20 can be divided into two types: large holes and small holes. Then, the breeding layer 20 with large holes is set in the upper part, and the breeding layer 20 with small holes is set in the lower part. At this time, when abalone is cultured in the upper part and sea cucumbers are cultured in the lower part, the excrement of the abalone falls into the breeding layer 20 at the lower part after passing through the large holes and gathers, so it can be provided as food for the sea cucumbers. Moreover, since the areas of the breeding layers 20 of each layer are different, different types of aquatic products can be distinguished, and the breeding layer 20 suitable for breeding can be selected to breed aquatic products.

[0056] As the culture layer, a net, a metal mesh, a frame, a synthetic resin sheet, a cloth, a concrete slab, a wooden board, etc. can be used.

[0057] On the stepped multi-layer breeding frame 100, the area of ​​each breeding layer 20 becomes wider as it goes down, and the area of ​​the food supply part 30 connected to the breeding layer 20 can also become wider accordingly. The porous components of the multi-layer breeding layer 20 are directly or indirectly fixed on the breeding frame body 10 or the food supply part 30.

[0058] In addition, the culture layer 20 can also be configured as a storage type, so that the growth of aquatic products cultured in the culture layer 20 can be easily confirmed, and it can be easily harvested and cleaned. The structure of the storage type culture layer 20 (including the food supply part) has, for example: a sliding method is provided on the culture frame body 10, and the culture layer 20 is stored or extracted in a drawer-like manner through the sliding method. Preferably, the sliding method is a structure that wraps the upper and lower parts of the culture layer 20 to prevent the culture layer 20 from shaking up and down, and a fixing piece can be included at the entrance, etc. to prevent the culture layer 20 from detaching.

[0059] In order to provide a safe growth space for aquatic products growing in the breeding layer 20 and to protect small seedlings from predators (natural enemies), a partition 21 can be formed. The partition 21 is arranged in various structures so as to divide the breeding layer 20 into two or more hiding places. The various structures at this time include plates, tubes, shaped or amorphous structures, cloth balls and other shapes, and their materials include synthetic resins, shells, metals, concrete, wood, stone, cloth, etc., and can also include holes through which only aquatic products and seedlings can move, but relatively large predators cannot pass through.

[0060] Fig.10 The figure shows a top view of the partition 21. A partition 21 is a shape with multiple hiding places formed on both sides based on the middle partition wall. Multiple partitions 21 can be arranged on the breeding layer 20 across the channel.

[0061] In addition, if Figures 11 to 13As shown, a moving channel 40 is included so that aquatic products grown in each layer of the culture layer 20 can be moved to other culture layers 20. The moving channel 40 may include: a first moving channel 41, which is connected to all (or part of a plurality of) culture layers 20; and a second moving channel 42, which is connected to the upper and lower adjacent culture layers 20. The first moving channel 41 is formed on one or more sides in a shape that conforms to the structure of the inclined or stepped culture frame body 10 and is long in the vertical direction (the length that can connect more than two layers of culture layers 20).

[0062] Preferably, the length of the second movable channel 42 is a length that can only be moved between the upper and lower adjacent breeding layers. While being connected to the first movable channel 41, a portion of it is connected to the bottom surface of the breeding layer 20, so that the aquatic products grown on the bottom surface of the breeding layer 20 can move to the upper or lower breeding layer 20 after passing through the first movable channel 41. The second movable channel 41 is configured to have a gentler slope than the first movable channel 41 (the slope of the first movable channel 41 is about 35 to 50 degrees, and the slope of the second movable channel 42 is about 20 to 30 degrees).

[0063] The second moving channel 42 may be used alone without being connected to the first moving channel 41. In this case, since the second moving channel 42 is connected to only two adjacent layers, it can only move between the two layers.

[0064] In addition, seaweed (seaweed) spores can be firmly set on the edge of one side or more than one layer of the breeding frame body 10, the breeding layer 20 and the food supply part 30 (seaweed (seaweed) is firmly suspended on the spores) to create an underwater seaweed forest, thereby forming blue carbon (blue carbon) with self-sufficiency in food and carbon sink and carbon storage effects.

[0065] <3. Food Supply Department 30>

[0066] The food supply part 30 is a part with food for aquaculture. It is different from the aquaculture layer 20 composed of porous components. The food supply part 30 is composed of a non-porous component without holes to prevent the loss of food due to the flow of water. It is fixed on the aquaculture frame body 10 and the aquaculture layer 20, and the food supply part 30 is a connection structure that communicates with the edge of the aquaculture layer 20, so that the aquatic products growing in the aquaculture layer 20 move to the food supply part 30 to eat food and then return to the aquaculture layer 20. The food supply part 30 can be a concave structure to accommodate a large amount of food, or it can be formed by tilting downward toward the aquaculture layer 20 so as to move the food to the aquaculture layer 20. In addition, according to the inclined or stepped structure of the aquaculture frame body 10, the upper part is naturally opened to receive and store food dropped from the upper part. At this time, in the case of an artificial aquaculture farm, the food is provided by the management personnel, and in the case of a natural aquaculture farm, the food is natural food in the seawater or food artificially sprinkled on the water surface.

[0067] The anti-collision wall 31 may be manufactured in the shape of a curtain, which is used to prevent the food gathered in the food supply portion 30 from falling outside the food supply portion 30 .

[0068] As another method of protecting aquatic products, a protection cage 50 ( Fig.15 ), the protection cage 50 includes: a net 51 for the aquaculture water to pass through; and a net frame 52, which is used to maintain the shape of the stepped multi-layer aquaculture frame 100. The net 51 can be formed on all surfaces (upper part, bottom part and periphery), or only formed on the upper part and periphery, and the bottom adopts other structures. At this time, preferably, the upper part is set to be able to use the ring 12 applied to the upper part of the aquaculture frame body 10.

[0069] <4. Connection and setting device 60 of the breeding frame>

[0070] The stepped multi-layer farming frame 100 constructed as described above can be used alone or in combination of two or more and connected in series. In this case, the stepped multi-layer farming frames 100 are connected by a connecting device.

[0071] Fig.16 2 is a diagram illustrating a preferred embodiment of the connection setting device, wherein the connection setting device 60 includes a first connection rod 61 and a second connection rod 62. A plurality of first connection rods 61 and second connection rods 62 may be used.

[0072] One side of the first connecting rod 61 is rotatably connected to the upper part of the breeding frame body 10 (it can be connected to a hanging ring already applied to the breeding frame body 10, or connected through an additional hinge protrusion), and the other side is a free part not connected to the breeding frame body 10. One side of the second connecting rod 62 is rotatably connected to the approximate center position of the bottom surface of the breeding frame body 10.

[0073] When the first connecting rod 61 and the second connecting rod 62 are not in use, and after the stepped multi-layer breeding frame 100 is connected, in order to prevent damage caused by the shaking of the first connecting rod 61 and the second connecting rod 62 and the stepped multi-layer breeding frame 100, and in order to maintain the connection state of the stepped multi-layer breeding frame 100, the first connecting rod 61 and the second connecting rod 62 can be fixed to the breeding frame body 10 by the fastening device 65. When in use, the first connecting rod 61 and the second connecting rod 62 can be freely rotated by releasing the fixation of the fastening device 65, and the fastening device 65 can use conventional clamps, metal wires, etc.

[0074] The initial state of the first connecting rod 61 and the second connecting rod 62 is that the free ends are not adjacent to each other but are arranged on opposite sides. This initial state is also the position for horizontally connecting the stepped multi-layer farming frame 100.

[0075] As described above, by continuously connecting the adjacent first stepped multi-layer breeding frames 100-1 and second stepped multi-layer breeding frames 100-2, second stepped multi-layer breeding frames 100-2 and third stepped multi-layer breeding frames 100-3 along the horizontal direction, the effect of connecting all the first stepped multi-layer breeding frames 100-1, second stepped multi-layer breeding frames 100-2 and third stepped multi-layer breeding frames 100-3 is achieved, and the upper and lower adjacent first stepped multi-layer breeding frames 100-1 and second stepped multi-layer breeding frames 100-2 are arranged in a row along the upper and lower directions. At this time, the uppermost breeding frame is fixed according to the setting status at sea and on land. For example, in the case of land breeding, the uppermost breeding frame can be hung on the bracket, and in the case of seawater breeding, the uppermost breeding frame can be fixed on a buoy floating on the water surface, or fixed on a wooden pile set on the seabed. In the case of seawater breeding, when the water level changes, the breeding frame can move up and down without damaging its connecting part through the hinge connection structure of the first connecting rod 61-1, the first connecting rod 61-2, the first connecting rod 61-3, the second connecting rod 62-1, the second connecting rod 62-2, and the second connecting rod 62-3.

[0076] The shape of the stopper 64 is formed on the rotation path of the first connecting rod 61 so that the first connecting rod 61 cannot rotate. Preferably, the angle of the stopper is slightly smaller than a right angle (90 degrees), that is, about 75 to 87 degrees, instead of a right angle (90 degrees).

[0077] The connection technology of the stepped multi-layer farming frame 100 using the connection setting device 60 described above is not limited to the aforementioned farming frame body 10, farming layer 20 and food supply part 30, and is an independent technology that can be applied to other types of farming frames.
