Specific details for implementing the invention

[0033] Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. However, the following drawings attached to this specification are intended to illustrate preferred embodiments of the present invention and serve to further enhance understanding of the technical concept of the present invention together with the aforementioned description; therefore, the present invention should not be interpreted as being limited only to the matters described in such drawings.

[0034] In this specification, the singular form includes the plural form unless specifically stated otherwise. Throughout the specification, the same reference numerals refer to the same components.

[0035] As used herein, "comprises" and / or "comprising" are used in the sense that they do not exclude the presence or addition of one or more other components other than the mentioned components.

[0036] Spatially relative terms such as "below," "underside," "lower side," "bottom," "lower part," "top," "top surface," "upper side," "top," and "upper part" may be used to easily describe the relationship between one component and another, as illustrated in the drawings. When spatially relative terms are used in addition to the directions depicted in the drawings, they should be understood as terms that encompass different directions.

[0037] For example, if a component illustrated in a drawing is flipped, a component described as being "below" or "lower" of another component may be placed "above" the other component. Therefore, the exemplary term "below" may include both the downward and upward directions.

[0038] As used in this specification, the term "connection" may be used to include both indirectly connecting and directly connecting a plurality of components.

[0039] As used in this specification, "vertical" or "horizontal" is used as a concept to describe the relative directional relationship of a specific component with respect to another component, the seabed, the sea surface, etc. Such terms should be understood as a concept that includes not only the direction depicted in the drawings but also directions that may vary depending on the installation state or environment of the device, and do not necessarily imply an absolute vertical or horizontal state.

[0040] Therefore, "vertical" should be interpreted to include a direction that is vertical or nearly vertical with respect to a relative component or the seafloor, etc., while "horizontal" should be interpreted to include a direction that is orthogonal or generally orthogonal to this. Additionally, "right angle" means that they are generally orthogonal to each other.

[0041] The present invention is designed to be applied primarily to cuttlefish (e.g., spotted cuttlefish, small cuttlefish, true cuttlefish; hereinafter collectively referred to as "cuttlefish" or "cuttlefish" for convenience), and can be applied in the same way to mollusks having similar spawning and habitat habits. 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.

[0043] FIG. 1 shows a spawning habitat for cuttlefish according to one embodiment of the present invention.

[0044] As illustrated in FIG. 1, a spawning habitat for cuttlefish according to one embodiment of the present invention comprises a net (120) fixed to the seabed, a net spawning structure (100) including a support block positioned in the center of the net (120) and tensioning the net (120) upward, a plurality of concrete supports (220) placed on the seabed, a bamboo spawning structure (200) including bamboo (240) vertically connected to the upper surface of each support, and a food structure (300) including a horizontal rope (320) positioned between the net spawning structure (100) and / or the bamboo spawning structure (200) on which seaweed (380) inhabits the surface, wherein the net spawning structure (100), the bamboo spawning structure (200), and the food structure (300) are arranged to be spaced apart from each other on the seabed.

[0045] FIG. 2 shows a net scattering structure (100) according to one embodiment of the present invention.

[0046] As illustrated in FIG. 2, a net scattering structure (100) according to one embodiment of the present invention includes a net (120) fixed to the seabed and a support block positioned in the center of the net (120) to tension the net (120) upward.

[0047] The above net (120) may be made of synthetic fiber material such as polyethylene or polypropylene and is formed in a flat shape of a square or polygon. The net (120) is spread out widely and fixed on the seabed, and its outer edge is fixed to the seabed through a rope support (122). A support block is placed in the center of the net (120), and the support block has a flat bottom so that it is stably settled on the seabed and lifts the net (120) upward from the center.

[0048] The upper part of the support block may include a gentle slope, and accordingly, the net (120) has a sloped or three-dimensional structure in which the center protrudes and gradually becomes lower toward the outer edge. This structure forms a natural space where cuttlefish can spawn or hide, and provides a structure efficient for adhesive spawning.

[0050] In one embodiment of the present invention, the net (120) of the net scattering structure (100) has a rope support (122) attached to its outer edge, and the rope support (122) can be attached to a fixed part (400) installed on the seabed.

[0051] The net (120) of the above-mentioned net scattering structure (100) is spread out and fixed to the seabed, and in the present invention, it can be formed as a flat net (120) made of a flexible synthetic fiber material.

[0052] The above net (120) is tensioned upward by a support block positioned in the center, and its outer edge is extended in all directions and arranged in a planar manner. A rope support (122) is attached to the outer edge of the net (120). The rope support (122) may be formed of a flexible member in the form of a rope or strap and is connected to a fixing part (400) installed at each corner or vertex of a polygon.

[0053] The above rope support (122) is coupled to a fixing part (400) installed on the seabed. The fixing part (400) is a means for fixing the four directions of the net (120) from the outer edge of the net scattering structure (100), and is formed of a heavy body or a fastening member having fastening force, such as a concrete block, a square stone, or an anchor, depending on the seabed ground condition or environmental conditions of the installation site.

[0054] Concrete blocks are formed into rectangular or polygonal shapes with sufficient weight to settle on the seabed under their own weight, satisfying both structural stability and ease of construction. Square stones are artificial or natural stones with a specific shape and mass; materials available on-site can be selected and applied according to marine site conditions, making them effective in areas requiring eco-friendly installation. Anchors are structures inserted into the seabed to secure anchoring force and can be used in conjunction with concrete blocks or square stones, primarily in sandy seabeds or areas with strong currents.

[0055] Each fixed part (400) is installed by being buried or settled on the seabed, and a fastening ring (420) is formed on the upper surface of the fixed part (400). The fastening ring (420) is a fixing means for directly connecting the end of the rope support (122), and can be formed as a metal ring, ring, hook, or clamp structure, and can be embedded in the fixed part (400) or integrally molded. The rope support (122) is connected to the fastening ring (420) by a fixing tie, or the end of the rope support (122) includes a fixing ring (122a) and is connected to the fastening ring (420) of the fixed part (400).

[0056] FIG. 2 shows a configuration in which each corner of a net (120) spread out in all directions on the seabed is connected to a fixed part (400) through a rope support (122), and a fastening ring (420) protrudes from the upper center or edge of each fixed part (400) and is connected to a corresponding fixing ring (122a) formed at the end of the rope support (122).

[0057] This connection structure minimizes vibration and displacement caused by seabed currents or waves, and prevents the net (120) from being deformed or pushed away, thereby stably maintaining the spawning space of cuttlefish. In addition, the fixing part (400) is easy to maintain after installation, and when replacing the net (120) or rope support (122), it can be easily replaced by separating the connecting link (fixing link (122a) and fastening link (420)).

[0059] A support block (140) according to one embodiment of the present invention has a flat lower surface formed to rest on the seabed and is formed in the shape of a square column or a cylinder, and a net (120) is in contact with the upper surface of the support block (140) so that the net (120) can be stretched in all directions from the center.

[0060] The support block (140) is intended to tension the central part of the net (120) installed on the seabed upward, is positioned below the net (120), and lifts the center of the net (120) upward. Due to the support block (140), the net (120) is not laid flat but is formed in a three-dimensional shape with a raised center.

[0061] The lower part of the support block (140) is formed flat and rests on the seabed. By forming the contact surface with the seabed as a flat plane, a stable support base is formed, and it can be positioned correctly on the seabed without the need for separate fixing means during installation.

[0062] The support block (140) is formed in the shape of a square column or a cylinder. The square column shape provides structural support from four sides, which can evenly distribute the tensile force of the net (120), and has the advantage of being able to be stably positioned without rotation or twisting during construction. The cylinder shape has the same radius in all directions, so it can minimize resistance to flow in the seabed environment. The shape can be selectively applied depending on the shape of the habitat, flow conditions, and installation conditions.

[0063] The upper surface of the support block (140) is formed in a structure in which the net (120) comes into direct contact. The net (120) is in close contact with the upper surface of the support block (140) at the center and is lifted upward by the support block (140). As a result, the net (120) is stretched in all directions from the center and maintains an upwardly raised shape.

[0064] FIG. 2 illustrates a state in which the support block (140) is positioned at the center of the mesh (120). The external shape of the support block (140) can be changed according to the installation conditions and can be formed from cement mortar, concrete, or high-density plastic material.

[0065] Accordingly, by stably settling the support block (140) according to one embodiment of the present invention on the seabed, the center of the net (120) is lifted upward to tension the entire net (120) three-dimensionally, and the stability of the net spawning structure (100) by the central tension structure can be maintained. Accordingly, a spawning surface preferred by cuttlefish is naturally formed, and the efficiency of attaching fertilized eggs can be improved.

[0067] A support block (140) according to one embodiment of the present invention includes an upper surface that is gently inclined upward, and a net (120) is stretched along the inclined upper surface so that the net (120) can form an inclined structure or a three-dimensional structure.

[0068] The support block (140) is a central tension structure that is placed on the seabed and lifts the center of the net (120) upward. The upper surface of the support block (140) is formed in a gently inclined shape, thereby having a structure that induces the net (120) to be uniformly tensioned from the center toward the outer direction.

[0069] The slope of the upper surface can be formed in the form of a straight slope, a curved slope, or a stepped slope, and the range of the slope can be adjusted according to the installation environment and the required angle of the net (120). In a general embodiment, the height of the support block (140) can be formed between approximately 200 mm and 400 mm, and the angle of inclination of the upper surface can be set within the range of approximately 10 degrees to 30 degrees.

[0070] The inclined upper surface is a surface to which the net (120) is in contact, and has a structure that gradually slopes downward from the center, thereby inducing the net (120) to spread out naturally from the top to the bottom. This structure ensures that when the net (120) is tensioned in all directions from the center of the support block (140), uniform tension is distributed outward, and the entire net (120) can stably maintain a centrally protruding three-dimensional structure. By maintaining a wide contact area with the net (120), the inclined surface ensures that the net (120) is stably tensioned across the entire surface without being concentrated at a specific point or compressed.

[0071] This allows for a more stable and effective spawning and concealment environment for cuttlefish. In particular, maintaining the three-dimensional structure of the net (120) prevents shaking and sagging due to seabed currents or changes in current speed, thereby allowing the net spawning structure (100) to maintain stability over the long term.

[0073] FIG. 3 shows a bamboo spawning structure (200) according to one embodiment of the present invention.

[0074] As shown in FIG. 3, a bamboo spawning structure (200) according to one embodiment of the present invention includes a plurality of concrete supports (220) that are placed on the seabed and bamboo (240) that is vertically connected to the upper surface of each support.

[0075] The above concrete support (220) is formed in a flat rectangular shape and is manufactured with self-weight so as not to be easily moved by ocean currents. In addition, considering ease of construction, it may be provided as a concrete precast structure or a cast-in-place structure.

[0076] A plurality of insertion holes (222) are formed on the upper surface of each concrete support (220), and a cut bamboo (240) is inserted vertically into the insertion holes (222).

[0077] The bamboo (240) is used as a rod-shaped material with a diameter of 25 mm to 30 mm and a length of 600 mm to 1000 mm, and is joined so as to protrude a certain height from the seabed. The bamboo (240) is arranged individually or in multiples, and each serves as a vertical spawning column for attaching the adhesive eggs of cuttlefish. The bamboo (240) has a rough surface and is made of natural material, so it is suitable for spawning, is environmentally friendly, and has the advantage of maintaining shape stability over a certain period of time.

[0078] The above bamboo spawning structure (200) is arranged at regular intervals in the direction of ocean current flow or in a direction perpendicular to it, and the spawning efficiency can be increased by adjusting the arrangement density.

[0080] A bamboo spawning structure (200) according to one embodiment of the present invention has a plurality of insertion holes (222) formed on the upper surface of each concrete support (220), and cut bamboo (240) is inserted and fixed in a vertical direction into the insertion holes (222) and formed to protrude a certain height above the seabed.

[0081] The insertion hole (222) has a cylindrical or square cross-section and is machined to a diameter that matches or is close to the outer diameter of the bamboo (240). Generally, the depth of the insertion hole (222) is formed within the range of 50 mm to 150 mm so that the bamboo (240) is not easily shaken or detached by external force even after being inserted.

[0082] A cut bamboo (240) is inserted and fixed in a vertical direction into the insertion hole (222). The bamboo (240) is a rod-shaped cut material with a diameter of 25 mm to 30 mm and a length of 600 mm to 1000 mm, and is inserted vertically into the insertion hole (222) so as to protrude upward from the upper surface of the concrete support (220).

[0083] The lower end of the bamboo (240) can be fixed inside the insertion hole (222) using friction or adhesive, and bolt fastening or wedge insertion methods may be used in combination as needed.

[0084] The installed bamboo (240) protrudes vertically above the seabed and serves as a vertical support column to which cuttlefish can attach adhesive eggs. This reflects the spawning habits of cuttlefish, which attach adhesive eggs to seaweed or crevices in rocks in the natural environment.

[0086] A concrete support (220) according to one embodiment of the present invention is formed in a flat rectangular shape, and a plurality of concrete supports (220) can be regularly arranged at regular intervals on the seabed based on the direction of ocean current flow or a direction perpendicular to it.

[0087] The above concrete support (220) is formed in a flat rectangular shape, so that it can be arranged without interference during construction and placement, and insertion holes (222) can be uniformly distributed and a large contact area with the seabed can be secured, allowing for stable seating.

[0088] In addition, the rectangular shape provides a reference plane that reduces interference with adjacent concrete supports (220) and clearly sets the spacing between the net spawning structure (100) and the feeding structure (300). In a general embodiment, the size of the supports can be formed in the range of length 500 mm, width 300 mm, and height 80 mm.

[0089] Multiple concrete supports (220) are arranged in a regular pattern at regular intervals on the seabed based on the direction of ocean current flow or a direction perpendicular to it. The arrangement criteria are selected based on the arrangement direction of the entire habitat and seawater flow conditions, and depending on the ocean current, a parallel arrangement (in the same direction as the current velocity) or a cross arrangement (perpendicular direction) method may be applied.

[0090] The spacing between each concrete support (220) is generally set to between about 500mm and 1000mm, which is a range that takes into account the arrangement density between the bamboo (240).

[0091] Accordingly, according to one embodiment of the present invention, by forming a concrete support (220) in a flat rectangular shape and arranging it at regular intervals on the seabed based on the direction of ocean current flow or a direction perpendicular to it, the repeated installation and maintenance of the bamboo spawning structure (200) can be facilitated, and structural stability and construction convenience can be improved.

[0093] A concrete support (220) according to one embodiment of the present invention has a length of 400 mm to 600 mm, a width of 300 mm to 350 mm, and a height of 70 mm to 100 mm, and the bamboo (240) may have a diameter of 25 mm to 30 mm and a length of 600 mm to 1000 mm.

[0094] The above concrete support (220) is a structure that settles on the seabed by its own weight and is formed in a flat rectangular shape, with a length of 400mm to 600mm, a width of 300mm to 350mm, and a height of 70mm to 100mm. This range is sufficient to satisfy the convenience of the worker during construction and structural stability against seabed currents, and in particular, the flat surface area is secured to provide the stability necessary for supporting the bamboo (240).

[0095] In one embodiment, the concrete stand (220) is manufactured using a precast method, making on-site installation easy, and has a weight of approximately 20 kg, which is sufficient for a single worker to perform underwater installation work. A plurality of insertion holes (222) are formed on the upper surface of the stand, and bamboo (240) is vertically inserted into these insertion holes (222) and fixed.

[0096] The bamboo (240) is a natural material with a diameter of 25 mm to 30 mm and a length of 600 mm to 1000 mm, and is harmless to the marine ecosystem. The bamboo (240) has a rough surface texture and the cut surface is easy to provide friction, so it can maintain fixation without a separate fastener when inserted into the insertion hole (222). If necessary, it can be fixed inside the insertion hole (222) using friction or adhesive, and bolt fastening or wedge insertion methods may be used in combination.

[0097] By limiting the dimensions of the concrete support (220) and the bamboo (240) in this way, the modularization of the bamboo spawning structure (200) is made possible, and concrete support (220) and bamboo (240) of the same dimensions can be mass-produced and arranged, making it easy to establish and maintain the habitat. In addition, considering the spawning habits of cuttlefish, bamboo of the above length can provide a suitable surface for attaching adhesive eggs.

[0099] FIG. 4 shows a feed structure (300) according to one embodiment of the present invention.

[0100] As illustrated in FIG. 4, the feeding structure (300) is positioned between the net spawning structure (100) and / or the bamboo spawning structure (200) and includes a horizontal rope (320) on which seaweed (380) inhabits the surface.

[0101] The horizontal rope (320) is made of a material with high seawater resistance, such as synthetic fibers like polyester, nylon, or polypropylene, and has an uneven or woven structure formed on its surface to facilitate the attachment of seaweed (380). Both ends of the horizontal rope (320) are connected to a vertical rope (340), and a buoyancy body (360) is attached to the upper end of the vertical rope (340) so that the horizontal rope (320) rises to a certain height above the seabed.

[0102] The height of the horizontal rope (320) is generally adjusted within tens of centimeters from the seabed and is set considering the photosynthetic conditions of seaweed and ocean current circulation. Native seaweed (380), such as kelp and wakame, grows on the surface of the horizontal rope (320), which serves as a shelter and initial food source for cuttlefish larvae. Additionally, the food structure (300) can increase the ecological diversity of the habitat by simultaneously providing a habitat for various marine organisms as well as cuttlefish.

[0104] In a feeding structure according to one embodiment of the present invention, both ends of a horizontal rope (320) are connected to a vertical rope (340), and a buoyancy body (360) is attached to the upper end of the vertical rope (340), so that the horizontal rope (320) rises to a certain height from the seabed.

[0105] The above-described feeding structure (300) includes a horizontal rope (320) that rises a certain distance upward from the seabed, and both ends of the horizontal rope (320) are connected to a vertical rope (340). The horizontal rope (320) is formed from a material with high seawater resistance, such as polyester, nylon, or polypropylene, and is installed in a horizontal direction while maintaining a certain tension. Both ends of the horizontal rope (320) are each connected to a vertical rope (340) by a connecting part (344), and the vertical rope (340) is a rope having the same material or similar strength as the horizontal rope (320), fixed to the seabed, and positioned by being stretched upward.

[0106] The connection between the horizontal rope (320) and the vertical rope (340) can be made by a knot without a separate member, or by a connecting part (344) provided at the connection point between the end of the horizontal rope (320) and the vertical rope (340). The end of the horizontal rope (320) connected to the connecting part (344) can be compressed and fixed to the vertical rope (340). This connection structure allows the horizontal rope (320) to be stably supported at both ends and minimizes shaking or sagging due to changes in the marine environment even after installation.

[0107] A buoyancy body (360) is attached to the upper end of the vertical rope (340). The buoyancy body (360) generates lift in the water and can be formed in the shape of a buoy or a buoyancy rod.

[0108] The above buoy is a circular or elliptical structure mainly filled with air or foam resin, and is formed from a material such as polyethylene or polyurethane that has durability and resilience. The buoyancy rod is formed from a foamed material or plastic material in the form of a thin rod, and by continuously connecting multiple rods to the upper part of the vertical rope (340), the vertical tensile force can be maintained at a constant level.

[0109] The lower end of the vertical rope (340) can be secured to a fastening loop (420) of a fixed part (400) formed on the seabed. The vertical rope (340) can be secured to the fastening loop (420) in a knot-like manner, or it can be secured by connecting it to a fixed loop (342a) formed at the end of the vertical rope (340). A buoyancy body (360) is attached to the upper end of the vertical rope (340) to maintain an upward tension state, thereby maintaining the vertical balance of the entire feeding structure (300).

[0110] By this structure, the horizontal rope (320) is maintained at a certain height above the seabed and is located in the middle layer of seawater where the flow is stabilized, providing a space for the attachment of seaweed (380) and for the hiding and movement of cuttlefish larvae.

[0111] In this way, a floating structure capable of attaching to seaweed (380) and concealing larvae can be formed, thereby providing a stable feeding environment suitable for the squid's ecology.

[0113] A horizontal rope (320) according to one embodiment of the present invention has an uneven surface or a woven structure formed on its surface, so that seaweed (380) can be attached to the outer surface of the horizontal rope (320).

[0114] The above-mentioned uneven structure is in the form of protrusions and depressions at regular intervals and depths, which can increase the adhesion of seaweed (380) and prevent detachment after attachment. The spacing of the unevenness is set to a range of 3mm to 10mm and the depth to a range of 0.5mm to 3mm, which affects the spore attachment density and initial attachment stability of the seaweed (380).

[0115] The above woven structure is formed by weaving the rope itself into a multi-strand or composite structure, and the rough fiber surface provides a structure favorable for the attachment of seaweed (380), and naturally occurring fine grooves help the attachment of seaweed spores or thread-like stems.

[0116] As such, according to one embodiment of the present invention, by forming an uneven structure or a woven structure on the surface of the horizontal rope (320), seaweed (380) can be naturally induced to attach to the outer surface of the horizontal rope (320), thereby forming a hiding space and habitat ecosystem for cuttlefish larvae and providing a food environment.

[0118] According to one embodiment of the present invention, the net spawning structure (100), the food structure (300), and the bamboo spawning structure (200) are arranged spaced apart from each other and arranged in order with respect to the direction of ocean current flow, and the structures can be repeatedly arranged in the same arrangement pattern.

[0119] The habitat is constructed by installing multiple structures on the seabed to ensure that the spawning, concealment, and feeding activities of cuttlefish are carried out continuously and stably. The habitat includes a net spawning structure (100), a feeding structure (300), and a bamboo spawning structure (200), and these components are arranged in a mutually complementary manner, taking into account not only structural functions but also ecological functions.

[0120] Specifically, a net spawning structure (100) is placed upstream of the ocean current, a food structure (300) is placed midstream, and a bamboo spawning structure (200) is placed downstream to minimize interference between the structures. This arrangement ensures that oxygen, nutrients, and food particles transported by the ocean current reach each structure evenly, and creates an environment favorable for the attachment and growth of seaweed, the dispersion of cuttlefish larvae, and the securing of spawning grounds. In addition, it creates an environment that is compatible with the habit of cuttlefish moving to nearby structures for concealment or feeding after spawning.

[0121] As a result, the arrangement of structures according to the embodiment of the present invention promotes spatial efficiency, minimizes interference between components, and allows each structure to be installed and maintained independently.

[0123] FIG. 5 shows a method for creating a spawning habitat for cuttlefish according to one embodiment of the present invention.

[0124] As illustrated in FIG. 5, a method for constructing a spawning habitat for cuttlefish according to one embodiment of the present invention may include the steps of: arranging support blocks at intervals on the seabed, positioning a net on the support blocks, fixing the net to the seabed, and tensioning the net upward to form a net spawning structure (S510); vertically joining cut bamboo to the upper surface of a concrete stand and arranging the concrete stand at intervals to form a bamboo spawning structure (S520); arranging a horizontal rope between the net spawning structure and / or the bamboo spawning structure and allowing seaweed to inhabit the horizontal rope to form a food structure (S530); and repeatedly arranging the net spawning structure, the bamboo spawning structure, and the food structure so as to be spaced apart with respect to the direction of seawater flow (S540).

[0125] First, a method for constructing a spawning habitat for cuttlefish according to one embodiment of the present invention forms a net spawning structure (S510).

[0126] Multiple support blocks are spaced apart on the seabed. The support blocks are formed with a flat bottom to rest stably on the seabed, and their tops are formed in a square or cylindrical shape with a center protruding upward, allowing the center of the net to be tensioned upward.

[0127] Next, the net is positioned on the support block, and a rope support is attached along the outer edge of the net. Then, the end of the rope support is fastened to a fixed part on the seabed to secure the net.

[0128] These fixed parts are secured to the seabed using concrete blocks, square stones, anchors, etc., and a fastening loop is formed on the upper surface of the fixed parts to connect with the end of the rope support. As a result, the net, with its center tensioned by the support blocks and its outer edge fixed, forms an inclined or three-dimensional structure, which provides a space suitable for the attachment of cuttlefish eggs.

[0130] And, a method for constructing a spawning habitat for cuttlefish according to one embodiment of the present invention forms a bamboo spawning structure (S520).

[0131] Multiple concrete supports are placed on the seabed at regular intervals. The concrete supports are formed in a flat rectangular shape with dimensions of 400mm to 600mm in length, 300mm to 350mm in width, and 70mm to 100mm in height. Multiple insertion holes are formed on the upper surface of each concrete support, and cut bamboo pieces with a diameter of 25mm to 30mm and a length of 600mm to 1000mm are vertically inserted into these holes and fixed so as to protrude. Bamboo is a natural material that is harmless to the marine ecosystem, and its rough surface texture is suitable for spawning and concealment. By arranging the concrete supports regularly based on the direction of ocean current flow or a direction perpendicular to it, the repeated installation and maintenance of the bamboo spawning structure are facilitated, and structural stability and ease of construction can be improved.

[0133] And, a method for constructing a spawning habitat for cuttlefish according to one embodiment of the present invention forms a food structure (S530).

[0134] A horizontal rope is placed in the gap between the above-mentioned net spawning structure and / or the bamboo spawning structure. Both ends of the horizontal rope are connected to a vertical rope, and a buoyancy body is attached to the upper end of the vertical rope to cause the horizontal rope to rise to a certain height above the seabed. The vertical rope is fixed to the seabed, and its upper end is tensioned by the buoyancy body. An uneven or woven structure is formed on the surface of the horizontal rope to allow seaweed to naturally attach. This creates an environment favorable for providing a hiding place and an initial food source for cuttlefish larvae.

[0136] And, a method for creating a spawning habitat for cuttlefish according to one embodiment of the present invention involves repeatedly arranging the entire structure so as to be spaced apart with respect to the direction of seawater flow (S540).

[0137] Net spawning structures, feeding structures, and bamboo spawning structures are arranged sequentially based on the direction of ocean currents, and the same structure arrangement pattern is repeated to form a habitat uniformly across the entire seafloor. The repetition interval is a minimum of 2m to 3m between structures, and they are arranged with consideration for the efficiency of construction and maintenance.

[0139] FIG. 6 shows an example of the arrangement of a cuttlefish spawning habitat in a marine environment according to one embodiment of the present invention.

[0140] As shown in Fig. 6, a natural hatching environment is created by a marine cage installed in the sea, through which naturally hatched fry move in the direction of the arrow to a habitat installed on the seabed.

[0141] The habitat consists of multiple net spawning structures, bamboo spawning structures, and feeding structures arranged on the seabed, and each structure is spaced apart on the seabed in consideration of the ecological characteristics of the fry.

[0142] In addition, multiple food structures (feeding grounds) are dispersed around the habitat, thereby inducing fry to voluntarily enter the habitat and grow.

[0144] As such, a cuttlefish spawning habitat according to one embodiment of the present invention can provide an integrated habitat environment that reflects the ecological habits of cuttlefish, such as spawning, concealment, and feeding activities, by forming a net spawning structure, a bamboo spawning structure, and a feeding structure, each reflecting structural and ecological functions.

[0145] In addition, the arrangement of structures according to one embodiment of the present invention promotes spatial efficiency, minimizes interference between components, and allows each structure to be installed and maintained independently.

[0147] 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
