[0023] The buoyancy chamber 1 provides overall buoyancy to ensure that the fish reef is suspended in the target water layer, the combination of the load bearing ring 5 and the vertical strip tentacles 2 simulates the form of a jellyfish, the strip tentacles 2 are hinged to swing naturally in the ocean current, enhancing the visual attraction to fish, and the strip tentacles 2 are automatically triggered by wave energy, the wave-encountering plate 10 is pushed by the wave impact to drive the arc-shaped moving plates 7, the kinetic energy is released after the spring 9 is compressed to periodically press down the pressing ring 11, the water pressure flows into the through holes 6 to force the strip tentacles 2 to swing at high frequency to simulate the movement mode of a jellyfish escaping from a natural enemy, effectively improving the dynamic collection effect on fish, and the anchoring assembly 4 is connected to the buoyancy chamber 1 through the connecting cable group 3 to allow the fish reef to swing within a limited range under the action of the wave while ensuring the stability of the position of the fish reef, avoiding structural damage caused by rigid fixation, solving the problem that the traditional bottom-sinking fish reef cannot effectively collect upper-layer fish, and the synergistic effect of the floating structure and the wave response makes the fish reef become a "living body" habitat, improving the fish aggregation efficiency.

[0024] Preferably, as shown in the drawings, Figures 1-2 The strip tentacles 2 comprise a plurality of woven belts 201 and a plurality of buoyancy balls 202, the buoyancy balls 202 are made of silica gel, the plurality of woven belts 201 and the plurality of buoyancy balls 202 are alternately connected in series, and the topmost woven belt 201 is located in the through hole 6.

The surface of the braided belt 201 is provided with degradable baiting fibers, which can be made of corn protein or chitin, continuously releasing glycine, nucleotides and other baiting agents.

[0030] Preferably, as shown in Figures 2-3 The braided belt 201 fixedly connected with a hinge ball 13 in the through hole 6, and a limiting groove 14 for limiting the hinge ball 13 is arranged in the through hole 6. There is a gap between the surface of the hinge ball 13 and the limiting groove 14. A plurality of inclined guide plates 16 are fixedly connected to the top of the hinge ball 13, and the plurality of guide plates 16 are arranged in the through hole 6.

[0031] In this embodiment, the gap between the hinge ball 13 and the limiting groove 14 allows the strip tentacle 2 to swing in multiple directions in wind and waves, avoiding breakage caused by rigid connection. The guide plates 16 are arranged on the top of the hinge ball 13, and the high-speed water flow is divided to reduce the vortex-induced vibration of the bearing ring 5, solving the structural failure problem of the floating fish reef in severe sea conditions, and achieving maintenance-free in the life cycle.

[0032] Preferably, as shown in Figures 1-4As shown, the connecting cable group 3 includes a center cable 301 and a plurality of main cables 302, one end of the plurality of main cables 302 is evenly articulated to the bottom of the buoyancy cabin 1, the other end converges to the center cable 301, the center cable 301 is fixedly connected with the anchoring assembly 4, the anchoring assembly 4 is provided as a ladder-shaped concrete block, a plurality of guide grooves 15 are formed on the surface of the anchoring assembly 4, a bite-proof sleeve 17 is sleeved on the surface of the center cable 301, and the bite-proof sleeve 17 is woven by stainless steel woven mesh.

[0034] The use method of the jellyfish-imitating structure floating fish reef is as follows:

[0035] According to the marine environment of the target water area and the target fish species, the weight of the anchoring base is selected, the buoyancy of the buoyancy cabin 1 is adjusted, the strip tentacle 2 is suspended in the target water layer, the center cable 301 of the connecting cable group 3 is fixed with the anchoring base, a plurality of main cables 302 are evenly articulated to the bottom of the buoyancy cabin 1, and a umbrella-shaped traction structure is formed as shown in Figure 4 .

[0036] When the wave impacts the wave-impingement plate 10, the arc-shaped moving plate 7 is pushed to slide along the surface of the buoyancy cabin 1, and the compression spring 9 is compressed to store energy; when the compression spring 9 is compressed to a critical point, the compression spring 9 quickly releases kinetic energy, drives the arc-shaped moving plate 7 to move in the opposite direction, and drives the extrusion ring 11 to extrude the surface of the bearing ring 5 downward.

[0037] The extrusion of the extrusion ring 11 forces the water in the bearing ring 5 to form a high-speed water flow through the through hole 6 as shown in Figure 3 The water flow impacts the articulated ball 13 at the top of the strip tentacle 2, and since there is a gap between the articulated ball 13 and the limiting groove 14, the strip tentacle 2 generates multidirectional high-frequency shaking, simulating the movement form of the jellyfish escaping from the natural enemy.

[0038] The shaking of the strip tentacle 2 forms a visual stimulus, attracts middle and upper layer fish to gather, the attachment groove 12 on the surface of the buoyancy ball 202 promotes the attachment of algae and barnacles, forms a natural bait library, and the degradable baiting fiber on the surface of the woven belt 201 continuously releases amino acid substances, so that the attraction radius is expanded to 50 meters.

[0039] In the ocean current, the gradually changing length of the braided band 201 and the gradually changing diameter of the buoyancy ball 202 reduce the vortex resistance, avoid the strip tentacle 2 winding the surface of the stainless steel anti-bite sleeve 17 of the central cable 301 to resist shark biting; the guide groove 15 of the ladder-shaped anchor base reduces sediment deposition and prevents displacement, and the guide plate 16 in the through hole 6 divides the high-speed water flow, reducing the vibration of the bearing ring 5.
