[0045] FIG. 1 is a schematic diagram of an underwater spawning protection device for marine animals according to one embodiment of the present invention.

[0046] Referring to FIG. 1, an underwater spawning protection device for marine animals according to one embodiment of the present invention may include a cage body (100) formed as a mesh structure, a plurality of spawning structures (200) installed inside the cage body (100), a supply unit (300) connected to the upper part of the cage body (100) and formed with a structure extending in the direction of the water surface and having an open top so as to provide food for the transplantation of adult animals, a buoyancy unit (400) connected to the upper part of the supply unit (300) to cause the supply unit (300) to float toward the water surface, and a tension member (500) connected between the cage body (100) and the supply unit (300) to maintain the supply unit (300) in a vertical state.

[0047] Although the present invention is designed to be applied primarily to cuttlefish (Sepiella japonica), it can be equally applied to mollusks with similar spawning and habitat habits, such as spotted squid (Sepioteuthis lessoniana). Therefore, the technical scope of the present invention is not limited to specific species and can be utilized for spawning, concealment, and habitat creation for various mollusks.

[0049] A cage body (100) according to one embodiment of the present invention is installed underwater to form an internal space, a scattering structure (200) is disposed in the internal space, and a supply unit (300), a tension member (500), etc. are connected to the outside.

[0050] The above cage body (100) is formed with a mesh structure to allow the flow of seawater to pass freely while preventing the intrusion of external predators. The mesh structure may be manufactured from a material such as stainless steel wire mesh or synthetic resin net (e.g., polypropylene net, etc.) to minimize corrosion or biological attachment in a marine environment.

[0051] The above cage body (100) may be formed in a polyhedron or hexahedron shape with a combination of multiple planes for stable anchoring and fixation to the seabed. For example, it may include at least a top surface, a bottom surface, left and right sides, and a front and rear surface, and each plane may be configured in a right angle or an inclined shape.

[0052] The above internal space provides sufficient size and openness to allow for the activity and spawning of adult organisms, as well as the initial growth and autonomous escape of larvae. According to one embodiment, the cage body (100) may be formed in the shape of a rectangular prism with a width of approximately 3,000 mm, a length of 2,000 mm, and a height of 1,500 mm. It may be formed in various shapes and sizes depending on the seabed environment.

[0054] A cage body (100) according to one embodiment of the present invention may be in the shape of a polyhedron or a hexahedron formed of a plurality of planes.

[0055] The above cage body (100) is formed with a plurality of planes, and these planes are connected to each other to form a polyhedron or a hexahedron shape, thereby having a three-dimensional and closed shape.

[0056] The above cage body (100) is based on a hexahedron structure composed of six planes including a top surface, a bottom surface, left and right sides, and a front and rear surface, and can be transformed into a polyhedron shape such as an octahedron or a dodecahedron by adding the number of planes as needed.

[0057] Each plane is formed with a net structure to enable the flow of seawater or the discharge of waste, and to prevent the intrusion of external predators. The connections between planes are secured by supports (120) to maintain structural rigidity, and in particular, a fixing member (140) is formed at a vertex located at the plane boundary to ensure that the supports (120) are stably secured.

[0058] FIG. 1 illustrates an underwater spawning protection device for marine animals with attached eggs according to the present invention, showing that the cage body (100) is formed in a cuboidal structure. FIG. 2 shows the cage body (100) in an underwater spawning protection device for marine animals with attached eggs according to one embodiment of the present invention.

[0059] As described above, the cage body (100) is preferably in a rectangular shape to maximize internal space and to ensure ease of installation and maintenance of the entire device.

[0060] According to one embodiment, the cage body (100) is formed as a rectangular prism with a width of approximately 3,000 mm, a length of 2,000 mm, and a height of 1,500 mm, and each plane is formed of stainless steel wire mesh or synthetic resin net, etc. Each plane can be manufactured independently and then interconnected, and a support (120) is formed at each corner and a fixing member (140) is placed at each vertex to stably maintain the entire outer perimeter. This structure has high durability against external forces such as ocean currents and waves, and deformation or damage can be minimized even during long-term installation.

[0062] According to one embodiment of the present invention, a support member (120) for supporting the outer edge of the cage body (100) may be attached along each planar boundary line of the cage body (100).

[0063] The above support (120) is installed along the boundary line of each plane constituting the cage body (100) to physically support the outer edge of the cage body (100) and stably maintain the overall shape.

[0064] In one embodiment, the support member (120) is positioned along the joint between each plane in a cage body (100) that is formed by connecting a plurality of planes in a polyhedral or hexahedral shape, thereby fixing the position of each plane and ensuring structural rigidity. In particular, since the cage body (100) in the present invention is formed as a net structure, by positioning the support member (120) along the outer edge, the net is prevented from sagging or being crushed, and is able to withstand external forces such as water pressure in a marine environment or repetitive waves or ocean currents.

[0065] The material and type of the support member (120) can be selected according to the underwater installation environment or installation assembly method of the underwater spawning protection device for marine animals attached to it. The support member (120) according to one embodiment of the present invention is formed from one or more of a rope, a rod, a cable, and a pipe, and may be composed of a single material or may use multiple materials in combination.

[0066] FIG. 2 shows a cage body (100) of a protection device for underwater spawning of marine animals according to an embodiment of the present invention, and includes a support member (120) arranged along each planar boundary line. As shown, the support member (120) is formed at the boundary line where the top, bottom, left side, right side, front, and rear planes meet, thereby maintaining the outer perimeter of the entire cage body (100) and improving structural rigidity.

[0068] According to one embodiment of the present disclosure, a fixing member (140) is formed at the vertex of the cage body (100), and the fixing member (140) can connect the ends of a plurality of adjacent supports (120) to each other.

[0069] In one embodiment, the fixing member (140) is formed in the form of a prism-shaped block or a three-way bridge at each vertex of the cage body (100), and a plurality of fasteners or coupling grooves (142) are provided on the inner or outer surface so that a plurality of supports (120) can be fitted or fixed in each direction.

[0070] In this way, the fixing member (140) according to one embodiment of the present invention connects the ends of adjacent support members (120) to each other, thereby further reinforcing the structural rigidity of the cage body (100) and minimizing deformation caused by external impact or underwater pressure.

[0072] According to one embodiment of the present invention, the fixing member (140) may include a fastener or a coupling groove (142) into which the end of the support member (120) is inserted or which surrounds the end of the support member (120).

[0073] The above fastening member or coupling groove (142) is formed to correspond to the shape and position of the support member (120), and the end of each support member (120) is inserted or fastened at a certain angle and direction.

[0074] For example, the above-mentioned fastener may be formed as a cylindrical or square insertion hole, and the coupling groove may be formed in a shape that covers the end of the support from the outside to wrap around the end of the support, and may be fixed using auxiliary materials such as a fixing pin, screw, or fastening band.

[0075] FIG. 3 illustrates a specific structure of a fixing member (140) according to one embodiment of the present invention, formed in the shape of a three-way bridge, and shows the ends of a support member (120) inserted into a fastening member (142) formed in each direction.

[0076] Specifically, the fixing member (140) may be formed from a durable material, such as reinforced plastic, stainless steel, or aluminum alloy, and its external shape may be formed as a prismatic block of approximately 100mm x 100mm x 100mm, with a circular fastening member (142) formed on each side into which a support member (120) with a diameter of 10mm can be inserted. Additionally, it may be formed in the shape of a three-way bridge with a length of approximately 100mm, with a circular fastening member (142) formed on each bridge into which a support member (120) with a diameter of 10mm can be inserted. A locking projection or a screw groove for fastening may be formed on the inner surface of the fastening member (142) to adjust the insertion depth, and a structure may be included in which a fastening pin or a fixing bolt is coupled to prevent the end of the support member (120) from coming out. Such a fixing member (140) may be implemented by a pre-assembly method or an on-site fastening method, and can be repeatedly installed and disassembled.

[0078] According to one embodiment of the present invention, a fixing ring (144) is formed on the fixing member (140) so as to be coupled to the end of the tension member (500).

[0079] The above fixing ring (144) enables the tension member (500) to be stably connected to the fixing member (140), and enables the position fixing and tension maintenance of the tension member (500), thereby maintaining the vertical state of the supply unit (300).

[0080] The above fixing ring (144) is generally formed in a ring shape or a hanging structure and can be connected to the tension member (500) by a knot, or can be connected in correspondence with the tension ring (520) formed at the end of the tension member (500). The shape of the fixing ring (144) can be circular, D-shaped, or U-shaped, and the material can be formed from reinforced plastic, stainless steel, or aluminum alloy, etc., capable of withstanding corrosion in seawater and repeated loads.

[0081] The above fixing ring (144) may be integrally formed on the outer surface of the fixing member (140) or subsequently attached by welding. Depending on the direction of the tension member (500) connected to the supply member (300), the installation location may be selectively positioned on the outer surface or the upper part of the fixing member (140), and multiple fixing rings (144) may be installed at each vertex.

[0082] According to one embodiment, the fixing ring (144) is formed of a stainless steel ring, and one or more are formed on the side of the fixing member (140) at regular intervals or at regular angles. The tension member (500) is formed of a synthetic fiber rope or cable, and a stainless steel tension ring (520) is formed at the end and is connected to the fixing ring (144) to be fixed. Such a structure allows for rapid connection and disconnection even underwater, thereby increasing work efficiency during maintenance, and maintains a constant tension even after connection, preventing tilting or shaking of the supply unit (300).

[0084] A spawning structure (200) according to one embodiment of the present invention is installed inside a cage body (100), particularly on a bottom surface adjacent to the bottom or bottom of the cage body (100), and provides a spawning surface on which cuttlefish can attach eggs.

[0085] The above-mentioned spawning structure (200) reflects the spawning habits of cuttlefish, namely cloaked spawning in shaded areas and surface attachment habits, and multiple structures may be arranged at regular intervals.

[0086] Fibers or artificial seaweed, etc., to increase adhesion may be attached to the outer surface of the above-mentioned spawning structure (200), thereby inducing the fertilized egg to naturally settle.

[0087] The scattering structure (200) is formed of polypropylene, polyethylene, or PVC material having corrosion resistance and strength suitable for a marine environment, and according to one embodiment, is formed in a conical shape with a narrow top and a wide bottom.

[0089] According to one embodiment of the present invention, the scattering structure (200) can be arranged at regular intervals on the bottom surface of the cage body (100).

[0090] The spawning structure (200) is placed at regular intervals on the bottom surface of the cage body (100), taking into account the ecological habits of cuttlefish, which prefer areas that are concealed from the outside or physically fixed areas, thereby inducing spawning activity to be distributed among individuals without structural interference.

[0091] The above spawning structure (200) is formed as an independent individual structure, and multiple structures may be arranged uniformly or, if necessary, non-uniformly on the bottom surface of the cage body (100). It is preferable that each spawning structure (200) be spaced at intervals of 500 mm or more to minimize interference between structures during installation and to ensure there are no problems with the movement paths of adult cuttlefish approaching, spawning, and leaving. The bottom arrangement reflects the natural flow of the spawned eggs descending.

[0092] FIGS. 1 and 2 illustrate a state in which a plurality of spawning structures (200) are arranged inside a cage body (100) according to an embodiment of the present invention, specifically showing a state in which the spawning structures (200) are arranged in a row or grid arrangement on the bottom surface. Such an arrangement disperses the spawning area to reduce the density of fertilized eggs and can provide an autonomous escape path after larval development.

[0093] According to one embodiment, the spawning structure (200) is formed in a conical shape with an upper diameter of 200 mm, a lower diameter of 300 mm, and a height of 500 mm, and a load-bearing fixed body is attached to the bottom so that it can be stably positioned on the bottom surface. The spawning structure (200) can be fixed to the bottom net of the cage body (100) using a fastening band or a fastening hook.

[0094] The outer surface of the above-mentioned spawning structure (200) is covered with an attachment substrate such as artificial seaweed, nylon fiber bundles, or plastic ribbons, which can increase the spawning induction effect of cuttlefish and improve the implantation rate of fertilized eggs.

[0096] According to one embodiment of the present invention, the scattering structure (200) may be formed in an upwardly reduced shape in which the upper width is smaller than the lower width.

[0097] The above upwardly reducing shape is generally formed as a conical, trapezoidal cylinder, or polygonal prism with an inclined structure, and has a structure in which the width gradually narrows from the bottom to the top. Such a shape stably induces the movement of the adult during spawning, ensures that fertilized eggs are evenly distributed on the attachment substrate attached to the spawning structure (200), and is also effective in maintaining the fertilized eggs so that they are not lost.

[0098] FIGS. 1 and 2 illustrate the external shape and arrangement of scattering structures (200) installed inside a cage body (100), each scattering structure (200) is shown in an upwardly reduced shape with a width that narrows as it goes toward the top.

[0099] As such, the spawning structure (200) according to one embodiment of the present invention is arranged at regular intervals on the bottom surface of the cage body (100) to prevent spawning interference between adult bodies and to induce dispersed implantation of fertilized eggs.

[0101] According to one embodiment of the present invention, a buoyancy body (220) may be coupled to the upper portion of the scattering structure (200) so that the scattering structure (200) maintains a vertical state underwater.

[0102] The spawning structure (200) is installed inside the cage body (100) so that adult cuttlefish can attach eggs, and its shape and arrangement, as well as its maintenance of shape underwater, can have a direct effect on the spawning success rate. The spawning structure (200) according to one embodiment of the present invention must maintain a stable vertical state underwater, and to this end, a buoyancy body (220) may be attached to the upper part of the spawning structure (200).

[0103] The above buoyancy body (220) is located inside the upper portion or externally connected in the direction of the central axis of the scattering structure (200), and is designed to provide sufficient buoyancy considering the overall length and weight of the scattering structure (200). Generally, it can be formed of an air-inflated float, a foamed polyethylene buoyancy body, a foamed polyurethane buoyancy body, etc.

[0104] FIGS. 1 and 2 illustrate a state in which a plurality of scattering structures (200) are arranged at regular intervals on the bottom surface of a cage body (100), and a circular buoyancy body (220) is attached to the upper part of each scattering structure (200) to maintain a vertical state.

[0105] According to one embodiment, the scattering structure (200) is formed in an upwardly reduced shape with a height of approximately 500 mm, a bottom diameter of approximately 300 mm, and a top diameter of approximately 200 mm, and a circular foam buoyancy body (220) with a diameter of approximately 150 mm and a thickness of 50 mm is attached to the upper part. A fixing body may be attached to the bottom of the scattering structure (200) and fixed to the bottom surface of the cage body (100) by a fastening band, so that the scattering structure (200) can float vertically in the water or maintain a fixed position through combination with the buoyancy body (220).

[0106] In this way, by maintaining the spawning structure (200) in a vertical state, the adult can stably approach the surface of the structure, and the spawned fertilized eggs are evenly attached to the outer surface of the spawning structure (200), providing an excellent growth environment.

[0108] According to one embodiment of the present invention, the supply unit (300) is a structure connected to and coupled to the upper part of the cage body (100), serving as a passage for transplanting an adult into the interior from the outside or injecting food. The supply unit (300) extends in the direction of the water surface and is formed with an open top so as to allow direct access from the outside. The supply unit (300) may be formed with a mesh-like structure to allow the flow of seawater in and out.

[0109] In addition to the supply path, the supply unit (300) can serve as a location identification standard when installing the device, and in one embodiment, it is positioned on the central axis of the cage body (100) and formed as a vertical structure with a diameter of 300 mm and a length of approximately 7,000 mm. An insertion opening (340) is formed at the top of the supply unit (300), and if necessary, a shielding opening (360) is formed to prevent the intrusion of external substances or external organisms.

[0111] A supply unit (300) according to one embodiment of the present invention may be formed as a mesh-like structure located on the central axis of the cage body (100) and vertically extended in the direction of the water surface.

[0112] The above supply unit (300) provides a path for transplanting and feeding adult cuttlefish, is connected to the upper part of the cage body (100), and is formed as an open structure connected from the water surface to the internal spawning space.

[0113] A supply unit (300) according to one embodiment of the present invention is structurally balanced by being located on the central axis of the cage body (100), and can implement the transplant path and food input path of an adult in a centralized manner.

[0114] The above supply unit (300) is formed as a mesh-like structure that extends vertically in the direction of the water surface. This connects the internal space of the cage body (100) and the water surface in a straight line, and the extension length can be adjusted according to the underwater depth, and forms a sufficient diameter and an insertion opening (340) to facilitate the entry of adult animals.

[0115] FIG. 1 illustrates a state in which a supply unit (300) is installed on the central axis of a cage body (100) and extended vertically, and FIG. 4 and FIG. 5 illustrate various embodiments of the supply unit (300). FIG. 4 illustrates the shape of the supply unit (300) including an insertion opening (340) and a shielding opening (360), and FIG. 5 illustrates an example in which an extension supply member (380) is detachably coupled so that the length of the supply unit (300) can be adjusted as needed.

[0116] Specifically, the supply unit (300) is formed as a mesh-like structure with a diameter of 300 mm and an overall length of approximately 7,000 mm, the upper end is formed to be close to the water surface or protrude about 300 mm above the water surface, and the lower end can be connected to the central upper surface of the cage body (100). The material of the supply unit (300) can be formed from a durable material resistant to corrosion and ocean currents, such as polypropylene, polyethylene, or marine PVC.

[0117] Thus, the arrangement of the supply unit (300) according to one embodiment of the present invention balances the buoyancy of the entire structure and promotes the efficiency of the supply path, and in particular, allows the tension member (500) to be symmetrically connected so that the supply unit (300) can be maintained in a vertical state. In addition, the central arrangement structure can be expected to have the effect of naturally guiding adult cuttlefish to the spawning structure (200) after they enter.

[0119] According to one embodiment of the present invention, an insertion port (340) for transplanting and feeding an adult is formed at the top of the supply unit (300), and the insertion port (340) may include a closable shielding port (360).

[0120] According to one embodiment of the present invention, the supply unit (300) can insert adult squid or feed through the top that is exposed above the water surface or close to the water surface from the outside. To this end, an insertion port (340) is formed at the top. The insertion port (340) is formed with an open structure to allow adult squid or feed to enter the supply unit (300), and includes a closable shield (360) to prevent contamination from the external environment, the entry of external organisms, or the escape of adult squid.

[0121] The insertion port (340) typically has a circular, elliptical, or square cross-section and is formed within a range that matches or is slightly larger than the inner diameter of the supply unit (300). The insertion port (340) is formed at the top of the supply unit (300) and may be installed at a position protruding about 200 to 500 mm from the outer water surface so that it is accessible to a worker above the water surface. However, it may be formed close to the water surface if necessary.

[0122] The insertion port (340) is provided with a shielding port (360), which can be implemented in a hinge structure or zipper manner to allow the operator to easily open and close it over the water surface, and may also be equipped with a locking latch or a magnetic locking structure. The material of the shielding port (360) is formed from a material with excellent flame resistance, such as polycarbonate, polypropylene, or stainless steel, and is formed to operate without damage even during repeated opening and closing operations.

[0123] FIGS. 1, FIGS. 4, and FIGS. 5 show an insertion opening (340) and a shielding opening (360) formed at the top of a supply unit (300), and as shown in FIG. 4, the insertion opening (340) is formed at the top of the supply unit (300), and the openable shielding opening (360) is connected in a hinge manner.

[0124] Specifically, the insertion opening (340) is formed from a circular polycarbonate plate with a diameter of approximately 300 mm and a thickness of approximately 5 mm and a diameter of approximately 320 mm, and a stainless steel hinge is installed on one edge and a locking latch or magnetic locking structure is formed on the opposite side so that it can be easily opened and closed from the outside. The shielding opening (360) may include a locking structure that prevents opening by wind, waves, or currents in a sealed state, and may also be implemented as a locking mechanism if necessary.

[0125] As such, the insertion port (340) and shielding port (360) according to one embodiment of the present invention serve to ensure the safe transplantation of an adult through the supply unit (300), as well as to protect the internal ecosystem from the external environment and facilitate the feeding process.

[0127] According to one embodiment of the present invention, the supply unit (300) is detachably coupled to the cage body (100), and the open area of ​​the cage body (100) formed when the supply unit (300) is separated can be closed by the detachable cover unit (160).

[0128] In one embodiment, the supply unit (300) is detachably coupled to the cage body (100), thereby facilitating transportation, storage, or maintenance. This detachable coupling structure is implemented through a zipper-type fastening structure (392) or a fastening band, rather than a fixed structure, between the cage body (100) and the supply unit (300), allowing a worker to easily disassemble and reassemble it as needed.

[0129] When the supply unit (300) is separated, an open area is formed on the upper part of the cage body (100). Since this open area can cause adult animals to escape and foreign substances to penetrate, a detachable cover unit (160) is provided to close the open area. In one embodiment, the detachable cover unit (160) is made to be easily disassembled and reassembled on the cage body (100) through a zipper-type fastening structure (392).

[0130] FIG. 1 illustrates a state in which the supply unit (300) is coupled to the top of the cage body (100), and FIG. 2 illustrates a cage body (100) with the supply unit (300) separated, showing a state in which a detachable cover unit (160) is fixed to an open area of ​​the cage body (100) by a zipper-type fastening structure (392).

[0131] The detachable structure of the cage body (100) and the supply unit (300) allows for maintenance to be easily performed by separating only the supply unit (300) without disassembling the entire device when repair or replacement of the supply unit (300) is required, and also enables the internal ecosystem of the cage body (100) to be protected from being exposed to the outside even after the supply unit (300) is removed.

[0133] According to one embodiment of the present invention, the supply unit (300) may have an extension supply member (380) detachably coupled to the upper or lower end of the supply unit (300) so that the length in the longitudinal direction can be adjusted.

[0134] The above supply unit (300) can adjust its height appropriately according to external environmental conditions, such as the distance between the water surface and the cage body (100), installation depth, and wave height conditions. To this end, an extension supply member (380) can be detachably coupled to the top or bottom of the supply unit (300) so that the length of the supply unit (300) can be adjusted in the longitudinal direction.

[0135] The extension supply member (380) can be optionally attached to the basic supply unit (300) to extend the total length, or detached when necessary to return to the original length. The extension supply member (380) can be optionally detachably coupled to the top or bottom of the supply unit (300), and each coupling position can be adjusted according to the installation environment.

[0136] FIG. 5 shows a state in which an extension supply member (380) is coupled to the lower end of a basic supply unit (300) according to one embodiment of the present invention. The extension supply member (380) can be coupled to the basic supply unit (300) by a zipper-type fastening structure (382) so as to be easily attached and detached.

[0137] Specifically, the supply unit (300) is basically formed as a cylindrical structure with a diameter of 300 mm and a length of 7,000 mm, and the extension supply member (380) is provided as 2 to 3 modules configured in units of 300 mm in diameter and 1,000 mm in length. Depending on the installation environment, the user can select one or more extension supply members (380) to extend the length of the supply unit (300) up to a maximum of 10,000 mm.

[0138] In this way, the extension supply member (380) according to one embodiment of the present invention can maintain a stable adult transplantation and food supply route even in areas with deep water or severe changes in water level.

[0140] A buoyancy unit (400) according to one embodiment of the present invention is coupled to the upper end of a supply unit (300) so as to cause the supply unit (300) to float, thereby causing the insertion port (340) to be exposed to the outside or the water surface, or to be close to the water surface.

[0141] The buoyancy unit (400) provides a sufficient amount of buoyancy to offset the gravity and water pressure acting on the supply unit (300), thereby keeping the supply unit (300) from tilting or sinking below the water surface. The buoyancy unit (400) is generally formed of a circular buoy, a ring float, or a tubular foam and has a light weight while possessing a certain structural rigidity.

[0142] In one embodiment, two circular buoys are placed on both sides of the top of the supply unit (300), and the diameter of each buoy is about 300 mm.

[0144] A tension member (500) according to one embodiment of the present invention connects the cage body (100) and the supply unit (300) and serves to maintain the vertical state of the supply unit (300).

[0145] The above tension member (500) is formed in the shape of a rope or cable and connects the upper vertex of the cage body (100) and the upper part of the supply unit (300). The above tension member (500) is installed to generate tension to minimize shaking or tilting of the supply unit (300) in seawater and to stably maintain the supply unit (300) in a vertical state with respect to the central axis.

[0146] The above tension member (500) is manufactured using materials such as stainless steel cable, nylon rope, or synthetic fiber cable, taking into consideration seawater resistance and tensile strength, and a tension loop (520) is formed at the end so that it can be connected to a fixing member (140) or a fixing loop (144).

[0148] A tension member (500) according to one embodiment of the present invention is formed of a rope or cable and is connected in multiple numbers between a fixing member (140) formed at a plurality of vertices located at the upper part of the cage body (100) and a fixing member (320) formed at the upper part of the supply unit (300), and can be arranged symmetrically with respect to each other with respect to the supply unit (300).

[0149] Here, "arranged symmetrically" means that the tension member (500) is connected at equal intervals and angles from a plurality of vertices of the cage body (100) with respect to the central axis of the supply unit (300).

[0150] The above tension member (500) is formed of a material that is structurally flexible and has high tensile strength, and is generally implemented as a rope or cable. The above tension member (500) is installed while maintaining a constant tension, and the vertical state of the supply unit (300) is maintained by minimizing relative displacement between structures.

[0151] The symmetrical connection structure of these tension members (500) ensures that the supply unit (300) does not deviate from its central position due to various external forces that may occur in the ocean, and promotes the efficiency of the internal adult transplantation and feed input path.

[0153] According to one embodiment of the present disclosure, a tension ring (520) is formed at both ends of a tension member (500), and a fixing ring (144) and (322) are formed on the fixing member (140) and (320), so that the tension ring (520) and the fixing ring (144) and (322) can be combined.

[0154] A tension member (500) is connected between a cage body (100) and a supply unit (300) to maintain the vertical state of the supply unit (300). Tension rings (520) are formed at both ends of the tension member (500), and fixing rings (144) and (322) are provided on fixing members (140) and (320) respectively formed on the supply unit (300) and the cage body (100), and the tension rings (520) and the fixing rings (144) and (322) are connected to each other.

[0155] The above tension ring (520) is a ring-shaped fastening means formed at both ends of the tension member (500), enabling stable fastening even when the tension member (500) is subjected to a tension load caused by external force or gravity. The above tension ring (520) is formed as a carabiner, snap hook, or locking ring structure and can be attached to the end of a rope or cable by compression, molding, or knotting.

[0156] The above fixing rings (144) and (322) are formed on the supply unit (300) and the fixing member (140) and (320) of the cage body (100), respectively, and are directly connected to the tension ring (520) to fix the tension member (500) so that it does not move out of the installation position. The fixing rings (144) and (322) are generally formed as D-shaped rings, circular rings, or slit-insertion ring structures, and are formed integrally with the fixing member (140) or fixed via screws or welding. In particular, the fixing rings (144) and (322) may be designed to protrude at a certain angle for convenience during installation, and connection with the tension ring (520) is easily achieved using a carabiner, snap hook, or locking ring structure.

[0157] FIG. 3 illustrates a fixing member (140) installed on a cage body (100) and a fixing ring (144) formed thereon, and FIG. 6 illustrates a tension member (500) having tension rings (snap hook type) (520) formed at both ends. As shown in FIG. 1, the underwater spawning protection device for marine animals attached to the cage shows a structure in which the tension member (500) is connected to the supply unit (300) and the cage body (100) and to the respective fixing members (140) and (320), and is formed so that the tension member (500) maintains tension even underwater.

[0158] Specifically, the tension member (500) is formed from a polyester or nylon rope with a diameter of 8 mm, and a total of 4 to 8 ropes are symmetrically arranged. The length of each rope is approximately 2,000 mm to 4,000 mm. A fixing member (320) with a fixing ring (322) formed thereon is positioned at the top of the supply member (300), and a fixing member (140) and a fixing ring (144) are provided at the apex of the cage body (100), and the tension rings (520) at both ends of the tension member (500) can be easily fastened through a carabiner, a snap-hook, or a locking ring structure.

[0160] According to one embodiment of the present disclosure, an opening (180) for internal inspection or maintenance is formed on one side of the cage body (100), and the opening (180) may be formed as a zipper-type fastening structure that can be repeatedly opened and closed in an underwater environment.

[0161] The opening (180) is formed on one side plane or one side corner of the cage body (100) and is used as an entry or hand insertion path for a worker to visually inspect the interior while underwater or to maintain the spawning structure (200), fertilized egg settling part (720), etc. installed inside. The opening (180) is preferably opened and closed using a zipper-type fastening structure so that it prevents unauthorized leakage of adult cuttlefish or larvae, while allowing the worker to easily operate it even while wearing gloves during underwater work.

[0162] The zipper-type fastening structure is integrally joined or sewn to the mesh structure of the cage body (100) or fixed using a fastening band. The zipper may include a stainless steel slider and a polyurethane zipper tape, taking into consideration the repeatability of opening and closing and underwater durability.

[0163] FIG. 2 shows a cage body (100) with the supply unit (300) separated, allowing the location of the opening (180) installed on one side to be confirmed. In one embodiment, the opening (180) is formed in an elliptical shape and is opened and closed by a zipper-type fastening structure. The zipper-type fastening structure is manufactured in the form of a slider so that it can be easily opened and closed with one hand even underwater, and a fastening hook is attached to the end of the slider to fix the open and closed state.

[0164] As such, according to one embodiment of the present invention, access to the inside of the cage body (100) is made possible by means of an opening (180) of a zipper-type fastening structure, thereby enabling rapid maintenance work such as checking the condition of fertilized eggs attached to the spawning structure (200), replacing the attachment substrate, removing contaminants, and monitoring biological reactions.

[0166] According to one embodiment of the present invention, a weight or fixing part (620) may be attached to the lower part of the cage body (100) so as to be fixed to the seabed.

[0167] Since the cage body (100) is installed in an underwater environment that is susceptible to external environmental influences such as waves or changes in currents, in one embodiment of the present invention, a weight or a fixing part (620) is attached to the lower part of the cage body (100) so that the entire device can be stably fixed to the seabed.

[0168] A weight according to one embodiment pulls the device downward by its own weight and may be formed of a concrete block, a metal plate, a high-density plastic weight, etc. The weight is uniformly distributed at the bottom of the four corners or on the entire bottom surface of the cage body (100) and may be positioned at the bottom structure of the cage body (100) and secured via a rope or a fastening band.

[0169] According to one embodiment, the fixing part (620) is a method of mechanically fastening the cage body (100) to the seabed using a structure such as a separate fixing device or an anchor.

[0170] These weights or fixed parts (620) are provided with a fastening ring so as to be coupled with a fixed ring (144) formed on a fixed member (140) of the cage body (100), thereby facilitating the convenience of fastening and fixing.

[0171] According to the embodiment, four concrete blocks weighing 50 kg or more are fastened to the bottom of the four corners of the cage body (100), and each weight is connected to the cage body (100) through a stainless steel fastening band or chain. Additionally, the fixing part (620) is fixed to the seabed by an anchor with a diameter of 30 mm having a fastening loop formed thereon, and is fastened to the fixing loop (144) of the bottom fixing member (140) of the cage body (100).

[0172] This configuration minimizes the movement of the underwater spawning protection device for marine animals attached to the eggs due to external impacts such as waves or changes in currents, thereby allowing the spawning structure (200) and the fertilized egg settling part (720) installed inside to function stably. In particular, since the weight and the fixing part (620) can be applied in parallel or selectively, they are applied according to the water depth, seabed conditions, current strength, etc. of the installation area.

[0174] According to one embodiment of the present invention, an egg attachment portion (720) made of a net or a flexible material may be disposed in the upper inner part of the cage body (100) so that fertilized eggs can be attached or settled thereon. The egg attachment portion (720) allows fertilized eggs of cuttlefish to be attached or naturally settled after spawning.

[0175] The above-mentioned fertilized egg attachment portion (720) has a structure that is spread out in a horizontal direction and is formed of a material with a rough surface and adhesive properties so that fertilized eggs can be freely dispersed and attached. In particular, because fertilized eggs are attached in a cluster form to ceiling-type or side-type structures due to the spawning characteristics of cuttlefish, the present invention positions the fertilized eggs in the upper part of the interior of the cage body (100) to induce the floating or drifting fertilized eggs to naturally come into contact with the attachment portion.

[0176] FIG. 7 illustrates a state in which a fertilized egg settling portion (720) is installed in a marine animal underwater spawning protection device according to an embodiment of the present invention, and a net or mesh structure is formed horizontally spread out on the upper side inside the cage body (100). The fertilized egg settling portion (720) may be formed of a polypropylene net, a nylon net, or a polyester fabric, etc.

[0177] The above-mentioned fertilized egg mounting portion (720) is connected to the inner wall or support (120) of the cage body (100) through a fastener or a fastening ring, and can be formed in a detachable structure for maintenance or replacement when necessary.

[0179] According to one embodiment of the present invention, the fertilized egg settling portion (720) can be positioned without interference between the bottom of the supply portion (300) and the top of the spawning structure (200).

[0180] The above-mentioned fertilized egg attachment portion (720) is positioned so as not to interfere with other components within the internal space of the underwater spawning protection device for marine animals, and is formed in a position particularly suitable for the spawning and attachment ecology of cuttlefish fertilized eggs.

[0181] In the present invention, the supply unit (300) is for transplanting adult squid and supplying food, and is installed by extending along the upper central axis of the cage body (100) in the direction of the water surface. Additionally, the spawning structure (200) is an attachment structure arranged at regular intervals on the bottom or lower area of ​​the cage body (100), and serves as an attachment support for the squid to perform spawning. Accordingly, the fertilized egg attachment unit (720) is preferably located in the space between the bottom of the supply unit (300) and the top of the spawning structure (200), so that the transplanting path of the adult squid, the food supply path, the spawning behavior, and the stable attachment environment of the fertilized egg are not mutually interfered with.

[0182] FIG. 7 shows that the fertilized egg attachment section (720) is formed in a horizontal structure and is positioned with sufficient clearance between the lower outlet of the supply section (300) and the uppermost part of the spawning structure (200). The fertilized egg attachment section (720) is formed in a flexible net or mesh structure so as not to obstruct the free passage of adult cuttlefish descending from the bottom of the supply section (300), and to induce the fertilized eggs that occur after spawning to naturally attach.

[0183] Specifically, the fertilized egg settling portion (720) is formed of a mesh sheet made of polyester material and is connected to the inner wall of the cage body (100) or the support (120) between the lower portion of the supply portion (300) and the upper portion of the spawning structure (200) through a fastening band or the like.

[0184] Accordingly, by setting the position of the fertilized egg settling part (720) according to one embodiment of the present invention, the movement path of the adult cuttlefish is not interfered with when approaching the spawning structure (200) or descending from the supply part (300), and the fertilized egg can be stably settled on the fertilized egg settling part (720) without being lost.

[0186] As such, the underwater spawning protection device for marine animals with attached eggs according to one embodiment of the present invention comprises a cage body, a spawning structure, a supply unit, a buoyancy unit, and a tension member, thereby enabling the transplantation of adult animals, feeding, spawning, and protection of fertilized eggs to be performed within a single device while maintaining structural stability underwater.

[0188] The description above is merely an example of applying the principles of the present invention, and other configurations may be further included without departing from the scope of the present invention. For example, at least some of the various embodiments of the present invention described above may be combined. Explanation of the symbols
