Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] Example:

[0028] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, in the embodiments of this utility model are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0029] It should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0032] The bottom-enclosed artificial reef type marine ranching platform provided by this utility model includes a main hull 1 and a fish protection wall 4. The main hull 1 is provided with a number of columns 2. The columns 2 are arranged around the main hull 1 and adjacent columns 2 are connected by netting to form aquaculture cages 3. The fish protection wall 4 is set inside the aquaculture cages 3. The two ends of the fish protection wall 4 are respectively connected to two adjacent columns 2 to reinforce the bottom edge of the aquaculture cages 3. The fish protection wall 4 has a number of independent cavities 5.

[0033] Specifically, compared to traditional aquaculture cages on deep-sea platforms, this invention adds a fish-protecting wall 4 to the bottom of the aquaculture cage 3. The fish-protecting wall 4 contains multiple cavities 5, which can serve as shelters. This design draws inspiration from the iconic Hakka walled village, a building embodying the survival wisdom and cultural heritage of the Hakka people over thousands of years. With the addition of the "walled village" (i.e., the fish-protecting wall), on the one hand, it provides an additional physical barrier when ocean currents change abruptly, allowing fish to swim into the cavities and avoid adverse effects from the currents, thus improving their survival rate. On the other hand, the "walled village" further strengthens the stability of the aquaculture cage 3, resisting various ocean current impacts and preventing damage to the cage, which could lead to fish escaping.

[0034] As an optional implementation, in some embodiments, various artificial reefs (not shown in the figure) are set up within the space enclosed by the fish protection wall 4. These artificial reefs provide fish with a habitat similar to natural reefs, allowing them to find hiding places and reducing stress responses caused by environmental discomfort or predator threats. Simultaneously, the presence of artificial reefs makes fish feel safer, helping them stabilize their emotions, reduce energy consumption, and thus promote growth. Furthermore, the installation of artificial reefs increases water flow and exchange area, facilitating oxygen dissolution and increasing dissolved oxygen levels, providing a better living environment for fish. Additionally, biofilms easily form on the surface of the artificial reefs; the microorganisms on these biofilms can decompose organic matter and harmful substances in the water, helping to purify the water and reduce aquaculture pollution.

[0035] In the above embodiments, the artificial reef further includes a biomimetic coral reef, a spiral upwelling reef, or a multi-tiered composite reef. The biomimetic coral reef, with its branching structure mimicking natural coral and a porosity >60%, provides shelter for juvenile fish, increasing their survival rate by 40%-60%. The spiral upwelling reef's spiral blades induce vertical seawater flow, creating nutrient-rich zones that can increase plankton density by 3 to 5 times. The multi-tiered composite reef has a concrete base (for pressure resistance), an alloy frame (for attached organisms), and a floating plastic tube surface (for light collection). This vertical spatial layering allows it to adapt to the habits of different fish species.

[0036] As an optional implementation, in some embodiments, the fish enclosure 4 has several openings 6, which are respectively located on the inner wall and top of the enclosure 4. This structural design, which increases the accessibility of the cavity 5 for fish, can promote fish behavior and physiological health. First, the cavity 5 provides a natural shelter for fish, allowing them to avoid predators, rest, and reproduce. This sense of security helps reduce stress responses in fish and promotes their healthy growth. Second, fish have an instinct to explore their environment. Increasing the accessibility of the cavity 5 can stimulate exploratory behavior in fish, promote their physical activity, and help maintain their vitality and health. Finally, some fish tend to reproduce within the concealed cavity 5. Increasing the ease of access to the cavity 5 can improve the reproductive success rate of fish and contribute to the propagation of the population.

[0037] As an optional implementation, in some embodiments, the fish enclosure 4, which is set along the width direction of the main hull 1, also has a channel 7 that penetrates through the fish enclosure 4. In this way, the fish swimming from one small enclosure to another helps the flow and circulation of water, improves water quality, reduces the accumulation of harmful substances, and the design of multiple small enclosures also makes water quality monitoring and control more flexible and precise, allowing for corresponding control measures to be taken according to the water quality conditions of different enclosures.

[0038] As an optional implementation, in some embodiments, a ballast tank 8 is provided inside the column 2. The buoyancy of the aquaculture cage 3 can be adjusted by changing the ballast water volume in the ballast tank 8, thereby also adjusting the submersion depth of the fish protection wall 4, which can better resist the impact of deep-sea currents on the fish in the aquaculture cage 3.

[0039] As an optional implementation, in some embodiments, a sewage tank 9 is also provided inside the column 2, and a sewage outlet (not shown in the figure) is also provided in the cavity. The sewage outlet is connected to the sewage tank 9 through a pipe. In order to maintain the balance of the aquatic ecosystem in the cavity, after the sewage outlet is set, the organic matter such as fish feces and uneaten food will be discharged from the cavity in a timely manner through the action of water flow, reducing their accumulation in the cavity. Furthermore, the discharged fish feces and uneaten food and other organic matter are transported to the sewage tank 9 through the pipe for treatment, so that they meet the discharge standards or are transformed into valuable resources, realizing green environmental protection and resource recycling.

[0040] As an optional implementation, in some embodiments, the fish enclosure 4 is made of polyethylene or polypropylene. Polyethylene possesses excellent corrosion resistance, abrasion resistance, and flexibility, enabling it to withstand the erosion of seawater, the impact of waves, and friction from marine life in the complex environment of the deep sea. Its relatively low density facilitates processing and installation, and its relatively low cost makes it suitable for large-scale deep-sea aquaculture applications. Polypropylene also exhibits excellent corrosion resistance and mechanical properties, with high strength capable of withstanding significant tensile and compressive forces, helping to maintain the shape and stability of the net cage. Polypropylene also has good heat resistance, maintaining good performance even in aquaculture environments with high temperatures.
