Description

Technical Field

[0001] The present invention belongs to the technical field of aquaculture, and particularly relates to a Sebastiscus marmoratus breeding device. Background Art

[0002] Sebastiscus marmoratus has rich nutritional value and high economic value. In recent years, with the increase in fishing intensity, the resource quantity of Sebastiscus marmoratus shows a downward trend. Therefore, it is necessary to further study the breeding technology of Sebastiscus marmoratus to meet the needs of farmers for fry and at the same time, through stock enhancement, repair and protect natural resources. In order to reduce the stress response of fry during transportation, reduce the loss of released fry, and let the fry adapt to the water temperature and salinity environment of the release area in advance, the best way is to temporarily raise the fry in the release area for a certain period of time, and then release them after the fry adapt to the external environment to improve the wild survival rate of the fry.

[0003] The invention application with the publication number KR1020170009407A relates to an aquaculture device and method for aquatic organisms using a culture cage. Fresh seawater is pumped in from the seabed through a motor pump, and a feed supply device is installed at a certain part of the pipeline through which the incoming seawater flows. The aquaculture method of aquatic organisms is that after the required amount of feed drops, the incoming seawater and the feed are mixed together and supplied to a feed cage formed inside a culture cage arranged on the seabed. The feed flowing in with the seawater stays inside the feed cage, and the feed and the seawater are gradually decomposed into fine particles together and move to the culture cage outside the cage to become the food of aquatic organisms. This device plays a role in purifying the culture cage while supplying feed.

[0004] The invention patent with the authorization number ES2233186B1 discloses a composite circular floating cage for fish farming, which is composed of concentric polyethylene pipes fixed in the sea and will provide buoyancy and resistance for the whole system. The system has radial metal or plastic brackets around the pipeline and keeps it in place by dividing the system into several parts. The top of the bracket should be configured as a passable walkway. In this way, access to the cage from both sides can be guaranteed. The culture cages should be immersed in water and located in the space between every two pipe crowns and every two brackets. They are made of metal or reinforced plastic and have holes at the bottom to allow water to pass through. These cages should be subject to the main structure composed of the above-mentioned pipes and brackets through chains or wooden stakes. The purpose of this invention is to establish such a fish nursery that can operate at sea, avoiding occupying coastal areas and the cost of pumping and transferring water in existing fishing grounds.

[0005] Analyzing the above-mentioned prior art, aquaculture cages are gradually developing towards multifunctionality. However, since the survival rate of Sebastiscus marmoratus larvae is greatly affected by wind waves and predators, and most of the existing aquaculture cages have poor anti-wind and wave performance and are not very suitable for use in sea areas with large wind waves, which limits the effect of stock enhancement of Sebastiscus marmoratus. Summary of the Invention

[0006] The purpose of the present invention is to provide a brown scorpionfish breeding device for breeding and proliferation and release of brown scorpionfish, which has good wind and wave resistance and high stability, can reduce the risk of cage capsizing, and improve the survival rate of fry.

[0007] The technical solutions adopted by the present invention to achieve the above-mentioned purpose are:

[0008] A brown scorpionfish breeding device includes multiple cages, each comprising a frame and a net. The frame includes multiple vertical support rods, and the net is arranged around the frame and wrapped around the sides and bottom of the frame to form a box structure with an open top. The multiple cages are connected by flexible connectors. Specifically, the flexible connectors are used to connect the support rods or nets of two adjacent cages.

[0009] Furthermore, the net is movable, allowing for either blocking or connecting the interior of the aquaculture cage with the outside seawater, thereby facilitating the release of fry that have reached release standards. Specifically, the net can be movable by allowing the net on the side of the frame to move upward as a whole along the length of the support rods, or by allowing the bottom of the net on the side of the frame to roll up, connecting the aquaculture cage to the outside seawater from the side; or, alternatively, the net at the bottom of the aquaculture cage can be detached from the bottom of the frame, connecting the aquaculture cage to the outside seawater from the bottom.

[0010] By adopting the above technical solution, aquaculture cages can be placed in the area where brown scorpionfish are released, and used for the cultivation of fry or temporary rearing in batches. For example, fry of different ages or fry of different body length ranges can be placed in different aquaculture cages for rearing. After they reach the release standard, the internal space of the corresponding aquaculture cages can be connected to the external sea area by moving the net body to achieve reproduction and release. The structure of this device is simple. The arrangement of multiple aquaculture cages can expand the aquaculture space, and the fry can also be temporarily reared in different areas according to the situation of the fry. The provision of flexible connectors can reduce the impact between different aquaculture cages and improve the ability of the entire device to withstand wind and waves at sea. Specifically, aquaculture cage, especially aquaculture cages in the outer layer, will be in a state of constantly sinking and floating under the influence of wind and waves and its own buoyancy, and the range of movement is relatively large. Since the aquaculture cages are connected by flexible connectors, compared with rigid connections, the impact of this unstable state of the aquaculture cage on nearby aquaculture cages can be greatly reduced, thereby reducing the risk of all aquaculture cages capsizing. Furthermore, the cages' ability to rise and fall with the wind and waves also acts as a wave breaker, reducing the impact of seawater fluctuations on the inner cages or other nearby cages, thereby improving the stability of the inner cages. This allows young fry or those with insufficient body length to be placed in the inner cages for breeding, avoiding excessive stress and ensuring their normal growth. Fry close to release standards can be placed in the outer cages to facilitate their early adaptation to the aquaculture environment and improve their survival rate in the wild.

[0011] According to one embodiment of the present invention, the flexible connector includes a plurality of connecting monomers arranged in parallel, adjacent connecting monomers are flexibly connected, and the aquaculture cage is connected to the connecting monomers via a first rope body.

[0012] Furthermore, the multiple connection units are connected by flexible ropes, elastic parts or telescopic parts.

[0013] Thus, multiple connecting monomers arranged in parallel are flexibly connected. Under the action of water fluctuations, adjacent connecting monomers can move closer to or farther away from each other, and can sink or float with the water flow. The connecting monomers consume water energy during the activity, thereby reducing the impact of wind and waves on the aquaculture cages connected to them, improving stability, and preventing the device from tipping over or overturning.

[0014] According to one embodiment of the present invention, the connecting unit includes two vertically arranged first float rods, which are connected by a horizontally arranged second float rod, and floats are arranged at the upper and lower ends of the first float rod; a bending plate is arranged between the multiple connecting units, and the bending plate includes a plurality of upper bending parts and lower bending parts arranged at intervals, the upper bending part is arranged across the second float rod, and the lower bending part is arranged with a counterweight.

[0015] Specifically, the second floating rod contacts the lower surface of the bending plate, and the counterweight is arranged on the upper surface of the bending plate.

[0016] Furthermore, multiple groups of bending plates are arranged inside the flexible connecting member, and the multiple groups of bending plates are arranged along the length direction of the first floating rod.

[0017] Furthermore, a second rope body is connected between two relatively arranged first floating rods on the connecting monomer, and the counterweight is fixedly connected to the second rope body. The second rope body can slide along the length direction of the first floating rod.

[0018] Furthermore, the counterweight is spherical or oval.

[0019] Furthermore, the weight of the counterweight should be set according to the material of the bending part and the buoyancy of the connecting monomer, so as to maintain the bending state of the bending part and not drive the connecting monomer to sink.

[0020] Thus, sufficient buoyancy is provided by the first floating rod, the second floating rod and the floating ball, which can ensure that the connecting monomer floats or suspends in the water body and ensure the state stability of the entire flexible connecting member in the water. Through the connection of the first floating rod and the second floating rod, the connecting monomer has a stable frame structure. Bending plates are arranged between multiple connecting monomers to achieve flexible connection between the connecting monomers, so that the flexible connecting member becomes a unified whole that can continuously adjust the connection angle and connection height within a certain range.

[0021] Since the first floating rod, the second floating rod and the floating ball on the connecting monomer all have sufficient buoyancy, the bending plates connected thereto float up and down in the water. Therefore, the bending plates have a flow-slowing effect on the water body flowing from the space range of the flexible connecting member to the aquaculture cages connected to both sides thereof. When the fluctuating water body passes through the flexible connecting member, it is blocked by the stacked bending plates, thereby slowing down the water flow velocity, and thus the shaking of the cages caused by the relatively fast water flow velocity between the two aquaculture cages can be avoided. Since multiple upper bending parts and lower bending parts are arranged at intervals on the bending plates, when the water flow passes through the flexible connecting member, the flow direction is corrected multiple times to achieve the effect of rectifying the flow, thereby reducing the impact force of the water flow, especially large waves. Since the fry of Sebastiscus marmoratus begin to metamorphose into juveniles after 35 - 40 days of cultivation, and their inhabiting mode changes, from aggregating and floating in the water body to lurking against the wall and at the corner. Using the bending plates to intercept the water flow can reduce the adverse situations such as the fish school moving away from the side wall of the aquaculture cage and the reduction of the activity space of the fish school in the aquaculture cage due to the fish fry being disturbed by the too fast water flow.

[0022] During the process of using the bending plates to intercept or block the water flow and reduce the water body flow velocity, the second rope body and the counterweight arranged on the connecting monomer can ensure that the bending plates are always in a bent state, avoiding the bending plates from deforming under the impact of the water flow, especially preventing the reduction of the water body rectifying effect caused by the bending plates being in a flat plate structure or an approximate flat plate structure.

[0023] Specifically, in the case of relatively weak wind and waves, under the buoyancy of the connecting monomer and the gravity of the counterweight, the bending plate can maintain its bent state and be at a relatively stable height. That is to say, the multi-layer bending plates will not have a large range of up and down floating relative to the connecting monomer. When the wind and waves are large, the multiple bending plates arranged in an upper and lower stacked manner divide the space between the flexible connectors into multiple flow spaces. The water flow with a higher flow rate enters different flow spaces and impacts the bending plates at the upper and lower ends of the space. Under the impact of the water flow, the relative stability between the bending plate and the connecting monomer is damaged. For example, the upper bending part in some areas will float upward with the water flow. At this time, at the lower bending parts on both sides of this area, the upward floating amplitude is relatively weak under the restrictive action of the counterweight, so they will gather towards the upward floating upper bending part and drive the adjacent connecting monomers on the left and right sides to approach each other, causing the local space between two adjacent lower bending parts to be compressed. The water flow in this space is forced to decelerate and adjust its flow direction. Under the restrictive action of the upper bending part, lower bending part and connecting monomer on the outer side, this gathered space gradually adjusts to the initial state, and this adjustment process is not achieved in one step under the impact of the water flow, but is a continuous reciprocating process until the adjustment amplitude can be ignored. During this process, a large amount of water energy can be consumed, making the water flow towards the aquaculture net cage relatively stable.

[0024] In addition, through the up and down movement of the second rope body relative to the first floating rod, the position of the counterweight relative to the first floating rod can be adjusted, and the distance between the upper and lower bending plates can be adjusted, thereby adjusting the water flow rate passing through. When the water flow rate entering a certain flow space is large, under the impact of a large amount of water, the bending plate deforms, and it prompts the second rope body located at the lower bending part to drive the counterweight to move, thereby squeezing the two adjacent upper and lower flow spaces, so that this flow space expands relatively, which helps to reduce the water flow rate.

[0025] In addition, the bending plate can be stretched and deformed, and its deformation range is controllable. Through the deformation of the bending plate, the overall shape of the flexible connector can be adjusted, including the overall width, bending direction, angle, etc. When the flexible connector is connected to the net body of the aquaculture net cage through the first rope, it can ensure that the deformation of the net body of the aquaculture net cage under the impact of the water flow can be adjusted with the deformation of the bending plate, which helps to maintain the shape of the net body of the aquaculture net cage in the water. In addition, the deformation of the bending plate pulling the net bodies on both sides of the aquaculture net cage helps to remove attachments or blockages on the net body by pulling.

[0026] Furthermore, a sliding base is sleeved outside the support rod, and the sliding base is movably matched with the support rod; the sliding base includes a first through hole matched with the support rod and a second through hole matched with the first rope.

[0027] According to an embodiment of the present invention, a vertical rotating shaft is arranged inside the aquaculture cage, and the bottom of the rotating shaft is rotatably connected to the bottom of the frame body through a bearing or the like; a plurality of horizontally arranged net plates are connected to the outer wall of the rotating shaft, and the plurality of net plates are arranged in a staggered manner.

[0028] Furthermore, the distance between two adjacent net plates arranged vertically is 0.3 m - 1.0 m.

[0029] Furthermore, the net plate is fan-shaped.

[0030] Thus, through the cooperation of the rotatable shaft and the net plates, a habitat can be provided for Sebastiscus marmoratus fry. Especially when the fry metamorphose into juveniles and their habitat mode changes, the arrangement of the net plates can make full use of the space inside the aquaculture cage and prevent the fry from gathering in large numbers on the side walls of the aquaculture cage.

[0031] In addition, the rotation of the rotating shaft drives the net plates to rotate, which can promote the flow of water inside the aquaculture cage, promote the flow and replacement of the aquaculture water, and thus avoid the decline in the survival rate of fry caused by low dissolved oxygen content in the aquaculture space. The water flow also helps to drive the impurities (such as feed residues, fry excreta, etc.) inside the aquaculture cage to flow outside the aquaculture cage, maintaining the cleanliness inside the aquaculture space.

[0032] According to an embodiment of the present invention, the aquaculture cage is equipped with a feed feeding component. The feed feeding component includes a feeding funnel and a connecting rod. The connecting rod is rotatably connected to the bottom of the frame body, and the feeding funnel is sleeved outside the connecting rod; holes are provided on the side wall of the feeding funnel; a screening net plate is arranged inside the feeding funnel, and the outer edge of the screening net plate is elastically connected to the inner wall of the feeding funnel.

[0033] Thus, feed can be automatically fed into the aquaculture cage through the feed feeding component. Specifically, the feed is put into the feeding funnel from the top opening. After being screened by the screening net plate, the feed can be put into the aquaculture cage through the holes on the side wall of the feeding funnel for the fry to eat.

[0034] The connecting rod drives the feeding funnel to rotate. Under the action of centrifugal force, the feed inside the feeding funnel can be evenly sprinkled into the aquaculture cage, expanding the feed feeding range, improving the evenness of feed sprinkling, preventing the fry from competing due to overly concentrated feed, and reducing the injury rate and mortality rate of fry caused by fighting. In addition, the rotation of the feeding funnel can drive the water flow inside the aquaculture cage, thereby promoting the entry of fresh water into the aquaculture space, ensuring the oxygen content of the water, and improving the sewage discharge effect.

[0035] The screening net plate is connected to the feeding funnel through elastic members such as springs. Thus, during the screening process of the feed, due to the change in the weight of the feed above the screening net plate, the elastic members can deform, and then drive the vibration of the feeding funnel through the elastic members, preventing the feeding funnel from being blocked.

[0036] Furthermore, the feeding funnel can move up and down along the connecting rod. Further, the feeding funnel is made of lightweight materials and can be processed with buoyant materials such as wood and plastic.

[0037] Thus, it is convenient for precise feeding of feed. Specifically, when the feeding funnel is unloaded, it is located at the top of the connecting rod, and the feeding funnel can be exposed outside the seawater, so as to facilitate placing the feed into the interior of the feeding funnel. After the feed is put into the interior of the feeding funnel, under the action of gravity, the feeding funnel moves downward along the connecting rod until it enters the interior of the aquaculture net cage. During the downward movement of the feeding funnel, the water flow impacts the feed, which helps to improve the looseness of the feed, thereby improving the efficiency of the feed passing through the side wall of the feeding funnel and improving the feeding efficiency.

[0038] According to an embodiment of the present invention, an auxiliary feeding component is configured at the bottom of the feeding funnel. The auxiliary feeding component includes a turning plate body and a hinge shaft. The hinge shaft is arranged at the bottom edge of the feeding funnel. One end of the turning plate body is hinged to the hinge shaft. The turning plate body can rotate around the hinge shaft within a certain angle range. The other end of the turning plate body, that is, the free end of the turning plate body, extends in a direction away from the connecting rod; an intercepting plate is configured on the upper surface of the turning plate body, and the intercepting plate is inclined upward from the surface of the turning plate body.

[0039] Holes are evenly arranged on the turning plate body, and the turning plate body is processed with lightweight materials. Therefore, the turning plate body will not sink under the action of the buoyancy of the water body and is in an inclined or even horizontal state in the water body.

[0040] The free end of the intercepting plate (that is, the end far from the surface of the turning plate body) is inclined in a direction away from the feeding funnel.

[0041] The intercepting plate can be a strip-shaped plate with a length matching that of the turning plate body; the intercepting plate can also be set as multiple short plates arranged at intervals.

[0042] Thus, during the falling process of the feed discharged from the holes on the side wall of the feeding funnel, part of the feed spills onto the turning plate body and then falls through the holes on the turning plate body. When the amount of feed intercepted by the turning plate body is relatively large, the turning plate body rotates around the hinge shaft under the influence of gravity, and the feed on it is promoted to spread to the outer edge until it falls from the end. In this way, the feed can be prevented from concentrating in a certain area. During this process, the intercepting plate arranged on the upper surface of the turning plate body intercepts the moving feed, which can prevent too much feed from being dumped at one time during the rotation of the turning plate body, and can also achieve the effect of dispersing the feed and loosening the internal structure of the feed through the intercepting plate.

[0043] In addition, the setting of the turning plate body and the intercepting plate can promote the exchange of water between the upper and lower layers inside the aquaculture cage, and improve the balance of the water body in the aquaculture space. The turning plate body swings within a certain angle, causing water fluctuations and promoting water flow, which can prevent hypoxia inside the aquaculture cage. The up and down movement of the feeding funnel and the turning plate body also helps to collect plankton or garbage impurities on the upper layer or the surface layer of seawater, maintain a good aquaculture environment, and improve the survival rate of fry.

[0044] When the feed feeding stops, the feeding funnel and the turning plate body basically remain stationary, and also provide an additional habitat for Sebastiscus marmoratus fry, expanding the utilization space inside the aquaculture cage.

[0045] According to an embodiment of the present invention, the connecting rod includes a first connecting rod and a second connecting rod. The first connecting rod is vertically arranged, and the bottom of the first connecting rod is rotationally connected to the frame body through a bearing or the like. The bottom end of the second connecting rod is hinged to the top end of the first connecting rod, and a limiting member is provided at the connecting end of the first connecting rod and the second connecting rod; the feeding funnel is sleeved outside the second connecting rod.

[0046] Thus, the second connecting rod can drive the feeding funnel to swing back and forth around the axis of the first connecting rod within a certain range. In this way, on the one hand, the throwing range of the feed can be further expanded to achieve uniform feeding. The feed inside the feeding funnel is thrown out from the holes on the side wall under the action of inertia and the throwing range is expanded, which can avoid the blockage of the holes on the side wall of the feeding funnel and the sieve plate, and ensure the feeding effect of the feed. Under the limiting action of the limiting member, the swinging range of the second connecting rod is limited. When the second connecting rod swings to the limit position, the swinging feeding funnel produces a jerky motion, which can increase the amplitude of the local water body fluctuation, generate water body disturbance, improve the water body balance, and prevent local blockage of the net body. And, with the swinging of the feeding funnel, the feed inside it moves back and forth under the action of gravity. In this way, the sieve plate is unevenly stressed, and the elastic members such as springs at different positions on its outer edge are in a continuously adjusted state similar to "elongation - compression - elongation". Thus, the side wall of the feeding funnel continuously receives the vibration energy from the spring and is in an unstable state, further realizing the effect of improving sieving. In addition, this unstable state of the feeding funnel can enhance the disturbance of the nearby water body, and the water body carries the feed to flow, which can avoid the adhesion of the feed and the like on the net body.

[0047] Compared with the prior art, the present invention has the following beneficial effects:

[0048] 1. Two adjacent aquaculture cages are connected by a flexible connecting piece, which can prevent one aquaculture cage from driving the connected aquaculture cage after being affected by wind and waves, improve the overall stability of the device, and reduce the risk of capsizing;

[0049] 2. The flexible connector cooperates with the connecting unit and the bending plate. On the one hand, the bending plate has a slow flow effect, which prevents the aquaculture cage from shaking due to the fast water flow rate and ensures the utilization rate of the internal space of the aquaculture cage. In addition, the upper and lower bending plates and counterweights can be used to control the distance between the upper and lower bending plates to achieve the effect of controlling water flow.

[0050] 3. The rotating shaft is matched with the mesh plate to provide a habitat for the brown scorpionfish fry, which is in line with the living habits of the fry, improves the utilization rate of the internal space of the breeding cage, promotes water flow, improves the efficiency of water replacement, avoids the decline in the survival rate of the fry caused by low dissolved oxygen content in the breeding space, and improves the efficiency of discharging impurities from the breeding cage;

[0051] 4. Set up feed feeding components to expand the feeding range, improve the uniformity of feed throwing, and reduce the injury rate and mortality rate of fry caused by fighting; and it can drive the flow of water inside the breeding cage, ensure the oxygen content of the water, and improve the sewage discharge effect.

Specific embodiments

[0065] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0066] Embodiment 1

[0067] Figures 1 to 8 Schematically shows a Sebastiscus marmoratus breeding device according to an embodiment of the present invention. As shown in the figure, the device includes a plurality of aquaculture net cages 10 arranged side by side. The aquaculture net cage 10 includes a frame body 11 and a net body 13. The frame body 11 is a circular or square frame structure and includes a plurality of vertically arranged support rods 12. The net body 13 is disposed on the periphery of the frame body 11. The net body 13 wraps around the side and bottom of the frame body 11 to form a box structure with an open top. The net body 13 is movable relative to the frame body 11, so as to intercept or communicate between the inside of the aquaculture net cage 10 and the external sea water, so as to release the fry cultivated to the release standard. Specifically, the moving mode of the net body 13 can be that the net body 13 on the side of the frame body 11 moves upward as a whole along the length direction of the support rod 12, or the bottom of the net body 13 on the side of the frame body 11 is rolled up upward to communicate the aquaculture net cage 10 with the external sea area from the side; or, the net body 13 at the bottom of the aquaculture net cage 10 can be separated from the bottom of the frame body 11 to communicate the aquaculture net cage 10 with the external sea area from the bottom.

[0068] The breeding cages 10 can be placed in the brown scorpionfish release area for the cultivation of fry or temporary rearing in batches. For example, fry of different ages or fry of different lengths can be placed in different breeding cages 10 for breeding. After they reach the release standard, the internal space of the corresponding breeding cages 10 is connected to the external sea area by moving the net body 13 to achieve proliferation and release. Generally, fry with a shorter breeding age or insufficient body length can be placed in the inner breeding cages 10 for breeding to avoid excessive stress on the fry and ensure their normal growth; fry close to the release standard can be placed in the outer breeding cages 10 to facilitate the fry to adapt to the environment of the breeding sea area in advance and improve their survival rate in the wild.

[0069] Adjacent aquaculture cages 10 are connected by flexible connectors 20, which reduces the impact of different aquaculture cages 10 on each other and improves the overall system's ability to withstand wind and waves. Specifically, a single aquaculture cage 10, especially one in the outer layer, will constantly sink and float under the influence of wind and waves and its own buoyancy, and have a large range of movement. Because the aquaculture cages 10 are connected by flexible connectors 20, the impact of this unstable state of a cage 10 on nearby aquaculture cages 10 is significantly reduced compared to a rigid connection, thereby reducing the risk of all aquaculture cages 10 capsizing.

[0070] The flexible connector 20 includes a plurality of connecting units 21 arranged in parallel, with adjacent connecting units 21 being flexibly connected. The aquaculture cage 10 is connected to adjacent connecting units 21 via a first rope 14. In this embodiment, the flexible connector 20 is connected to the support rod 12 on the frame 11 of the aquaculture cage 10 via the first rope 14. A sliding base 15 is sleeved on the outer side of the support rod 12, and the sliding base 15 is movably engaged with the support rod 12. The sliding base 15 includes a first through hole 16 that cooperates with the support rod 12, and a second through hole 17 that cooperates with the first rope 14. The sliding base 15 can move up and down along the support rod 12 within a certain range, thereby achieving adjustable height of the flexible connector 20 relative to the aquaculture cage 10, which helps to improve the wave-breaking effect.

[0071] Specifically, the connecting monomer 21 includes two vertically arranged first floating rods 22, which are connected by a horizontally arranged second floating rod 23. Floating balls 24 are arranged at both the upper and lower ends of the first floating rod 22. Adjacent connecting monomers 21 are connected by a flexible rope, an elastic member, a telescopic member, etc. In this embodiment, the connecting monomer 21 is connected by a bending plate 31. A plurality of bending plates 31 are arranged side by side in the vertical direction between a plurality of connecting monomers 21. The bending plate 31 includes a plurality of upper bending portions 32 and lower bending portions 33 arranged at intervals. The upper bending portion 32 straddles the second floating rod 23, and a counterweight 35 is arranged on the lower bending portion 33. Through the connection between the first floating rod 22 and the second floating rod 23, the connecting monomer 21 has a stable frame structure. The bending plate 31 is arranged between a plurality of connecting monomers 21 to realize the flexible connection between the connecting monomers 21, so that the flexible connecting member 20 becomes a unified whole that can continuously adjust the connection angle and connection height within a certain range. Through the first floating rod 22, the second floating rod 23 and the floating ball 24, sufficient buoyancy is provided, which can ensure that the connecting monomer 21 floats or suspends in the water body, ensure the state stability of the entire flexible connecting member 20 in the water, and prevent the aquaculture cage 10 connected thereto from sinking due to its own gravity.

[0072] A second rope body 34 is connected between two relatively arranged first floating rods 22 on the connecting monomer 21, and the counterweight 35 is fixedly connected to the second rope body 34. And the second rope body 34 can slide along the length direction of the first floating rod 22. The counterweight 35 is spherical or oval, and its weight should be set according to the material of the bending portion and the buoyancy of the connecting monomer 21, so as to be able to maintain the bending state of the bending portion and not drive the connecting monomer 21 to sink.

[0073] The bending plate 31 floats up and down in the water under the buoyancy of the connecting monomer 21, and has a flow-slowing effect on the water flowing through the space range of the flexible connecting member 20 to the aquaculture cages 10 connected to both sides thereof. When the fluctuating water body passes through the flexible connecting member 20, it is blocked by the stacked bending plates 31, thereby slowing down the water flow velocity, and thus avoiding the shaking of the aquaculture cages 10 caused by the relatively fast water flow velocity between the two aquaculture cages 10. When the water flow passes through the flexible connecting member 20, through the interception of a plurality of upper bending portions 32 and lower bending portions 33, the flow direction is corrected multiple times to achieve the effect of rectifying the flow, thereby reducing the impact force of the water flow, especially large waves, and reducing the adverse conditions such as the fish group moving away from the side wall of the aquaculture cage 10 due to the fast water flow disturbing the fry and narrowing the activity space of the fish group in the aquaculture cage 10.

[0074] The deformation of the bending plate 31 can adjust the overall shape of the flexible connector 20, including the overall width, bending direction, angle, etc. In other embodiments, the flexible connector 20 is connected to the net body 13 of the aquaculture cage 10 through the first rope body 14. Thus, the structural adjustment of the flexible connector 20 will also drive the connected net body 13. Specifically, the deformation of the net body 13 of the aquaculture cage 10 under the action of water flow impact can be adjusted along with the deformation of the bending plate 31, which helps to maintain the shape of the net body 13 of the aquaculture cage 10 in water. In addition, the deformation of the bending plate 31 pulling the net bodies 13 of the two adjacent aquaculture cages 10 helps to remove the attachments or blockages on the net body 13 by pulling.

[0075] Inside the aquaculture cage 10, a vertically arranged rotating shaft 41 is configured. The bottom of the rotating shaft 41 is rotatably connected to the bottom of the frame body 11 through a bearing 42, etc.; a plurality of horizontally arranged fan-shaped net plates 43 are connected to the outer wall of the rotating shaft 41, and the plurality of net plates 43 are arranged in a staggered manner. And the distance between two adjacent net plates 43 arranged vertically is 0.3 m - 1.0 m.

[0076] Through the cooperation of the rotatable shaft 41 and the net plates 43, a habitat can be provided for Sebastiscus marmoratus fry. Especially when the fry metamorphose into juveniles and their habitat mode changes, the setting of the net plates 43 can make full use of the space inside the aquaculture cage 10 and prevent the fry from gathering in large numbers on the side walls of the aquaculture cage 10. In addition, the rotation of the rotating shaft 41 drives the net plates 43 to rotate, which can promote the flow of water inside the aquaculture cage 10, promote the flow and replacement of the aquaculture water, and thus avoid the decrease in the survival rate of fry caused by the low dissolved oxygen content in the aquaculture space. The water flow also helps to drive the impurities inside the aquaculture cage 10 to flow outside the aquaculture cage 10, maintaining the cleanliness inside the aquaculture space.

[0077] When using the breeding device of this embodiment to breed Sebastiscus marmoratus fry, the setting of the flexible connector 20 is used to prevent one aquaculture cage 10 from driving the connected aquaculture cages 10 after being affected by wind and waves, improving the overall stability of the device and reducing the risk of capsizing; and the flexible connector 20 rectifies the flowing water body, reducing the flow rate and adjusting the flow direction, avoiding or reducing the stress response of the fry, and improving the survival rate of the fry.

[0078] Embodiment 2

[0079] Figures 9 to 12 Schematically shows a Sebastiscus marmoratus breeding device according to another embodiment of the present invention. The difference from Embodiment 1 is that:

[0080] The aquaculture cage 10 is equipped with a feed feeding assembly, which includes a feeding hopper 51 and a connecting rod. The connecting rod is rotatably connected to the bottom of the frame 11, and the feeding hopper 51 is sleeved on the outside of the connecting rod; the side wall of the feeding hopper 51 is provided with a hole. The connecting rod drives the feeding hopper 51 to rotate. Under the action of centrifugal force, the feed inside the feeding hopper 51 is evenly distributed into the aquaculture cage 10, expanding the feeding range and improving the uniformity of feed distribution. This prevents fish fry from fighting over the feed due to excessive concentration, and reduces the injury rate and mortality rate of the fish fry caused by fighting. The rotation of the feeding hopper 51 can drive the water flow inside the aquaculture cage 10, thereby promoting the entry of fresh water into the aquaculture space, ensuring the oxygen content of the water, and improving the sewage discharge effect.

[0081] The connecting rod includes a first connecting rod and a second connecting rod 52. The first connecting rod is arranged vertically, and the bottom of the first connecting rod is rotatably connected to the frame 11 through a bearing 42, etc. The bottom end of the second connecting rod 52 is hinged to the top end of the first connecting rod, and the connecting end of the first connecting rod and the second connecting rod 52 is provided with a limit member 53; the feeding funnel 51 is sleeved on the outside of the second connecting rod 52 and can move back and forth along the length direction of the second connecting rod 52.

[0082] In this embodiment, the first connecting rod of the connecting rod and the rotating shaft 41 are the same rod body.

[0083] The feeding hopper 51 is made of lightweight material, such as wood or plastic, and can be crafted from buoyant materials. When empty, it is located at the top of the connecting rod and exposed to the seawater, making it easier to place feed inside. Once the feed is placed inside the feeding hopper 51, gravity forces it downward along the second connecting rod 52 at the top of the connecting rod until it enters the aquaculture cage 10. As the feeding hopper 51 moves downward, the water impacts the feed, helping to loosen it up and improve its efficiency in passing through the side walls of the feeding hopper 51, thereby enhancing feeding efficiency.

[0084] A sieving mesh 54 is provided inside the feeding hopper 51. The outer edge of the sieving mesh 54 is elastically connected to the inner wall of the feeding hopper 51 via a spring 55. Feed is sifted through the sieving mesh 54. During this process, the weight of the feed above the sieving mesh 54 changes, causing the elastic member to deform. This, in turn, drives the feeding hopper 51 to vibrate, preventing the feeding hopper 51 from clogging.

[0085] In addition, the second connecting rod 52 can drive the feeding funnel 51 to swing back and forth around the axis of the first connecting rod within a certain range. In this way, on the one hand, the throwing range of the feed can be further expanded. Under the limiting action of the limiting member 53, the swinging range of the second connecting rod 52 is limited. When the second connecting rod 52 swings to the limit position, the swinging feeding funnel 51 generates jerks, which can increase the fluctuation amplitude of the local water body, generate water body disturbance, improve the water body balance, and prevent local blockage of the net body 13. Moreover, as the feeding funnel 51 swings, the feed inside it moves back and forth under the action of gravity. In this way, the force on the screening mesh plate 54 is uneven, and elastic members such as the springs 55 at different positions on the outer edge of the screening mesh plate 54 are in a continuously adjusted state similar to "elongation - compression - elongation". As a result, the side wall of the feeding funnel 51 continuously receives the vibration energy from the springs 55 and is in an unstable state, further realizing the effect of improving screening. In addition, this unstable state of the feeding funnel 51 can enhance the disturbance of the nearby water body, and the water body carries the feed to flow, which can prevent the feed and the like from adhering to the net body 13.

[0086] An auxiliary feeding component is arranged at the bottom of the feeding funnel 51. The auxiliary feeding component includes a turning plate body 56 and a hinge shaft 57. The hinge shaft 57 is arranged at the bottom edge of the feeding funnel 51. One end of the turning plate body 56 is hinged to the hinge shaft 57. The turning plate body 56 can rotate around the hinge shaft 57 within a certain angle range. The other end of the turning plate body 56, that is, the free end of the turning plate body 56, extends in a direction away from the connecting rod; an intercepting plate 58 is arranged on the upper surface of the turning plate body 56, and the intercepting plate 58 is arranged obliquely upward from the surface of the turning plate body 56.

[0087] Holes are uniformly arranged on the turning plate body 56, and the turning plate body 56 is processed from a light material. Therefore, the turning plate body 56 will not sink under the action of the buoyancy of the water body and is in an inclined or even horizontal state in the water body.

[0088] One end of the intercepting plate 58 far from the surface of the turning plate body 56 is arranged obliquely in a direction away from the feeding funnel 51. In this embodiment, the intercepting plate 58 is a strip-shaped plate with a length matching that of the turning plate body 56. In other embodiments, the intercepting plate 58 can also be multiple short plates arranged at intervals.

[0089] During the fall of the feed discharged from the hole in the side wall of the feeding funnel 51, part of it spills onto the turning plate body 56 and then falls through the holes in the turning plate body 56. When the amount of feed intercepted by the turning plate body 56 is relatively large, affected by gravity, the turning plate body 56 rotates around the hinge shaft 57, and the feed on it is urged to spread towards the outer edge until it falls from the end. In this way, the concentration of feed in a certain area can be avoided. During this process, the intercepting plate 58 provided on the upper surface of the turning plate body 56 intercepts the moving feed, which can prevent too much feed from being dumped at one time during the rotation of the turning plate body 56, and can also achieve the effect of breaking up the feed and loosening the internal structure of the feed through the intercepting plate 58.

[0090] In addition, the setting of the turning plate body 56 and the intercepting plate 58 can promote the exchange between the upper and lower layers of water in the aquaculture cage 10 and improve the balance of the water body in the aquaculture space. The turning plate body 56 swings within a certain angle, causing water fluctuations and promoting water flow, which can prevent hypoxia inside the aquaculture cage 10. The up and down movement of the feeding funnel 51 and the turning plate body 56 is also helpful for collecting plankton or garbage impurities on the upper layer or surface of the seawater, maintaining a good aquaculture environment, and improving the survival rate of fry.

[0091] When the feed feeding stops, the feeding funnel 51 and the turning plate body 56 basically remain stationary, and also provide an additional habitat for the Sebastiscus marmoratus fry, expanding the utilization space inside the aquaculture cage 10.

[0092] The routine operations in the operation steps of the present invention are well known to those skilled in the art and will not be elaborated here.

[0093] The above-described embodiments have detailed the technical solutions of the present invention. It should be understood that the above is only the specific embodiments of the present invention and is not used to limit the present invention. Any modification, supplement, or substitution in a similar way within the principle scope of the present invention should be included in the protection scope of the present invention.
