Description

Technical Field

[0001] This invention relates to the field of sea bass breeding and aquaculture technology, and in particular to a feeding method specifically for sea bass aquaculture. Background Technology

[0002] Sea bass (such as spotted sea bass and European sea bass) are mid-to-upper-level active predatory fish that are accustomed to chasing live prey or suspended feed at high speed in open water. Seawater cage culture provides them with a larger activity space compared to land-based pond culture, allowing the sea bass to swim under the impact of seawater currents, which makes the sea bass meat firmer.

[0003] Chinese patent CN103766263B discloses a floating fish bait feeding device that is bird-proof and water-resistant. The device is characterized by: a cylindrical body with openings at both ends, the upper opening of which is covered by a mesh, and the lower opening of which remains open; several floats are evenly distributed on the outer wall of the cylindrical body, and the cylindrical body is partially floating on the water surface by the buoyancy provided by the floats, with a portion of the upper part of the cylindrical body protruding above the water surface.

[0004] The aforementioned patents and prior art have the following problems: The aforementioned patent, by setting up a centralized area, or cylinder, inside the net cage, causes excessive crowding among fish during the competition for food, increasing the risk of mutual abrasion and injury. For predatory fish, this could even lead to attacks. Furthermore, fish must swim through the opening at the bottom to reach the feeding area, further increasing the distance they must travel to avoid collisions and even attacks. In addition, the cylinder in the patent needs to be placed in the water for a long time. If fish live inside, they will be blocked from water flow, reducing their activity level. This can cause fish to swim faster due to lack of water flow impact, resulting in fattening and less firm flesh. Moreover, the cylinder, when placed in the water for a long time, can interfere with the water flow inside the net cage, and its surface can also breed algae and attached shellfish, further increasing the risk of shellfish abrading the fish's skin and causing infection after the skin abrasion. Therefore, it is not conducive to the large-scale farming of bass and other fish. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A feeding method specifically for sea bass aquaculture includes the following steps: S1. Internal and external support breeding: Multiple sets of external and internal rollers are set inside and outside the breeding box in the breeding unit so that the external and internal rollers in the feeding unit can clamp and support the side net of the breeding box. S2. Rotary feeding: By placing the extruded floating feed to be fed into the top of the feeding chamber inside the feeding arm, the feeding arm rotates, causing the feeding chamber to rotate at the top of the breeding tank, and the feed is rotated and scattered onto the water surface inside the breeding tank through several openings at the bottom of the feeding chamber. S3, Movable Blocking: When the feeding arm rotates, the movable sleeve in the blocking unit is lowered and unfolded, isolating the movable sleeve between the feed spreading area and the breeding box. The downward movement of the movable sleeve will press the counterweight ring at its bottom down to the bottom of the breeding box, causing the breeding box to be pressed down and stretched, giving the bass ample room to move. S4. Feed Residual Feed Cleaning: As the feeding arm rotates, it drives the outer and inner rollers to roll on the surface of the stretched aquaculture tank's side netting, causing the attached materials on the side netting surface to be rolled away. The bottom of the movable sleeve contacts the bottom of the aquaculture tank through a counterweight ring, thereby preventing the cleaned-off attached materials from entering the feed distribution area inside the movable sleeve. After the feeding and cleaning is completed, the movable sleeve is raised and reset, allowing seawater from outside the movable sleeve to enter the feed distribution area.

[0007] As a preferred embodiment of the feeding method for sea bass aquaculture described in this invention, wherein: The aquaculture unit in S1 also includes a top frame surrounding the top of the aquaculture box, and several floats are embedded inside the top frame. The bottom of the breeding box is fixedly connected to a bottom frame.

[0008] As a preferred embodiment of the feeding method for sea bass aquaculture described in this invention, wherein: The feeding unit in S1 also includes a central platform located in the center of the breeding box. A support column is fixedly connected to the bottom of the central platform. The support column passes through the breeding box, the bottom frame, the collection hopper, and the filter chamber from top to bottom and is then fixedly connected to the seabed rock.

[0009] As a preferred embodiment of the feeding method for sea bass aquaculture described in this invention, wherein: Several floats are embedded in the central platform at the center of the breeding box along its outer contour.

[0010] As a preferred embodiment of the feeding method for sea bass aquaculture described in this invention, wherein: A rotating component is fixedly connected to the top of the central platform, and a frustum is rotatably mounted on the top of the rotating component. The top of the truncated cone has several feeding arms along its outline. The truncated cone is fixedly connected by feeding arms and connecting arms, and the end of the feeding arm that is close to the connecting arm is higher than the end of the feeding arm that is close to the truncated cone.

[0011] As a preferred embodiment of the feeding method for sea bass aquaculture described in this invention, wherein: A sleeve frame is fixedly connected to the bottom of the connecting arm, and the sleeve frame is movably fitted onto the surface of the top frame; The frame is set on the inner and outer sides of the breeding box and is connected to the inner roller and the outer roller respectively. The outer roller and the inner roller are both composed of an inner central shaft and an elastic rubber cylinder rotatably set on the outside of the central shaft. The outer roller and the inner roller are in rolling contact with the breeding box through the cylinder.

[0012] As a preferred embodiment of the feeding method for sea bass aquaculture described in this invention, wherein: The blocking unit in S3 also includes an extension arm, which is symmetrically fixed to the top of the platform. A mounting bracket is installed on the top of the extension arm. A take-up reel is rotatably mounted on one side of the mounting bracket, and a take-up drive source is fixedly connected to the other side of the mounting bracket. The output shaft of the take-up drive source passes through the mounting bracket and connects to the surface of the take-up reel, so that the take-up drive source drives the take-up reel to rotate.

[0013] As a preferred embodiment of the feeding method for sea bass aquaculture described in this invention, wherein: The side of the winding reel is wound with a winding rope, and a counterweight ring is fixedly connected to the bottom of the winding rope, so that the winding rope pulls the counterweight ring to move up and down inside the breeding box.

[0014] As a preferred embodiment of the feeding method for sea bass aquaculture described in this invention, wherein: The top of the counterweight ring extends upward with a movable sleeve, and several metal rings are spaced apart on the outer side of the movable sleeve. A movable cavity is provided between the movable sleeve and the breeding box to accommodate the movement of the inner roller. The material feeding area with the opening at the bottom of the feeding chamber is located inside the movable sleeve.

[0015] As a preferred embodiment of the feeding method for sea bass aquaculture described in this invention, wherein: The collection unit in S4 includes a collection hopper located at the bottom of the breeding box for receiving uneaten feed and cleaning up fallen attachments, and a filter chamber is installed at the center of the bottom of the collection hopper. A support column is connected through the middle of the filter chamber, and a connecting pipe is provided on the side of the filter chamber.

[0016] The beneficial effects of this invention are: 1. After the movable sleeve comes into contact with the rearing tank, the feeding area of ​​the sea bass is temporarily closed relative to the side of the rearing tank. This reduces the impact of seawater flow on the feed, reduces the amount of feed flowing out of the movable sleeve, and reduces the ineffective swimming of the sea bass in chasing the washed-away feed. Meanwhile, the outer and inner rollers will roll on the surface of the rearing tank's side netting, which is stretched and pressed down by the counterweight ring. This will rub off the attached substances on the surface of the rearing tank's side netting, thereby improving the cleanliness of the rearing tank and extending the time required for the rearing tank to be pulled out of the water for cleaning and replacement. This also prevents excessive algae from clogging the mesh or shellfish from scratching the fish's skin. At the same time, when the outer and inner rollers are not moving, they will also support the rearing tank. During this process, the movable sleeve blocks the fish and the rearing tank, preventing the moving outer and inner rollers from coming into contact with the fish and reducing the risk of the fish being scratched by the moving inner rollers.

[0017] Second, the movable sleeve is made of rubber, thus acting as a flexible barrier. It absorbs and reduces the noise and vibration generated during the cleaning process to a certain extent, reducing direct disturbance to the fish. Similarly, as a barrier placed between the fish and the breeding tank, the bottom of the movable sleeve is in direct contact with the bottom of the breeding tank without any openings. This allows the movable sleeve to block the debris removed by the outer and inner rollers from the breeding tank, reducing the accumulation of debris in the middle of the breeding tank and its contact with the fish.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: This embodiment is an example Figures 1-4 As shown, a feeding method specifically for sea bass aquaculture includes the following steps: S1. Internal and external support breeding: Multiple sets of outer rollers 305 and inner rollers 306 are set inside and outside the breeding box 101 in the breeding unit 1, so that the outer rollers 305 and inner rollers 306 in the feeding unit 3 clamp and support the side net of the breeding box 101. S2, Rotary feeding: By placing the extruded floating feed to be fed into the top of the feeding chamber 3041 inside the feeding arm 304, the feeding arm 304 rotates, causing the feeding chamber 3041 to rotate on the top of the breeding tank 101, so that several openings at the bottom of the feeding chamber 3041 rotate and scatter the feed onto the water surface inside the breeding tank 101. S3, Movable blocking: When the feeding arm 304 rotates, the movable sleeve 401 in the blocking unit 4 is lowered and unfolded, so that the movable sleeve 401 is isolated between the feed spreading area and the breeding box 101. The downward movement of the movable sleeve 401 will press the counterweight ring 402 at its bottom down to the bottom of the breeding box 101, so that the breeding box 101 is pressed down and stretched, giving the bass enough room to move. S4. Feed Residual Feed Cleaning: As the feeding arm 304 rotates, it drives the outer roller 305 and inner roller 306 to roll on the side net surface of the stretched aquaculture tank 101, causing the attached materials on the side net surface of the aquaculture tank 101 to be rolled and cleaned. The bottom of the movable sleeve 401 contacts the bottom of the aquaculture tank 101 through the counterweight ring 402, thereby preventing the cleaned-off attached materials from entering the feed distribution area inside the movable sleeve 401. After the feeding and cleaning is completed, the movable sleeve 401 is raised and reset, allowing seawater outside the movable sleeve 401 to enter the feed distribution area.

[0022] like Figure 1 and Figure 9 As shown, the breeding unit 1 in S1 also includes a top frame 102 surrounding the top of the breeding box 101, and a plurality of floats 1021 are embedded inside the top frame 102. The bottom of the aquaculture tank 101 is fixedly connected to a bottom frame 1011. Several cables 103 can be movably connected along the outline of the bottom frame 1011 on its outer side. The bottom of the cables 103 is fixed to the surface of the seabed rocks.

[0023] The breeding box 101 is preferably a wire cage, which is composed of a bottom net and a side net. The bottom frame 1011 is preferably composed of a cross plate and an outer ring of the cross plate at the bottom of the breeding box 101. Operation process: The buoy 1021 set on the top of the culture tank 101 generates buoyancy and pulls the top of the culture tank 101 upward. The bottom frame 1011 set at the bottom of the culture tank 101 pulls the culture tank 101 downward through its own weight. Several cables 103 can be set along the outer contour of the culture tank 101 to fix the bottom of the cables 103 to the seabed rocks, thereby reducing the swaying of the culture tank 101 in seawater culture and preventing it from being affected by seabed currents and shifting away from the culture area.

[0024] Example 2: This embodiment differs from the first embodiment in that: like Figures 4-5As shown, the feeding unit 3 in S1 also includes a central platform 301 located at the center of the breeding box 101. A support column 3011 is fixedly connected to the bottom of the central platform 301. The support column 3011 passes through the breeding box 101, the bottom frame 1011, the collection hopper 201, and the filter chamber 202 from top to bottom and is then fixedly connected to the seabed rock. The breeding box 101 and the bottom frame 1011 are slidably mounted on the surface of the support column 3011 through their central bushings. The collection hopper 201 and the filter chamber 202 are fixedly connected to the surface of the support column 3011. When the breeding box 101 and the bottom frame 1011 are pressed down and moved by the counterweight ring 402, there is a gap between the bottom frame 1011 and the collection hopper 201. The filter chamber 202 is preferably composed of a cylindrical frame and a filter screen covering the surface of the cylindrical frame.

[0025] like Figures 1-4 As shown, several floats 3012 are embedded inside the central platform 301 located at the center of the breeding box 101 along its outer contour.

[0026] The first float 1021 and the second float 3012 are preferably made of polyethylene or composite materials; Therefore, by fixing the middle platform 301 with the float 3012 or the support column 3011, the position of the middle platform 301 can be restricted by the floating of the float 3012 or the support of the support column 3011.

[0027] like Figure 5 , Figure 6 as well as Figure 9 As shown, a rotating component 302 is fixedly connected to the top of the central platform 301, and a frustum 303 is rotatably mounted on the top of the rotating component 302. The top of the frustum 303 is provided with a plurality of feeding arms 304 along its outline. The frustum 303 is fixedly connected by the feeding arms 304 and the connecting arm 3042, and the end of the feeding arm 304 that is close to the connecting arm 3042 is higher than the end of the feeding arm 304 that is close to the frustum 303.

[0028] The rotating component 302 is preferably composed of a waterproof motor and a cylinder on the top of the motor. The waterproof motor is fitted with a waterproof shell on its outer side, and the output shaft of the waterproof motor is fixedly connected to the cylinder and the frustum 303. The rest of the structure is the same as in Example 1.

[0029] The feeding arm 304 is inclined between the truncated cone 303 and the connecting arm 3042. When feed is put into the feeding cavity 3041 inside the feeding arm 304, the inclination of the feeding arm 304 guides the feed put into the feeding arm 304 on the side of the connecting arm 3042, so that it moves closer to the middle of the truncated cone 301 along the slope of the feeding arm 304. With the rotation of the feeding arm 304, the feed in the feeding cavity 3041 inside the feeding arm 304 can be evenly scattered on the top of the breeding tank 101, which is convenient for the bass to compete for food. Since bass are mid-to-upper-level feeding fish, the rotation of the feeding arm 304 and the longitudinal distribution of the feeding cavity 3041 along the feeding arm 304 can make the feed inside the feeding cavity 3041 evenly scattered on the water surface of the breeding tank 101, reducing the situation of excessive squeezing and competing for food by bass, which can lead to oxygen deficiency and damage from collisions.

[0030] Example 3: This example differs from other examples in that: like Figure 5 , Figure 7 as well as Figure 9 As shown, a sleeve frame 3043 is fixedly connected to the bottom of the connecting arm 3042. The sleeve frame 3043 is movably sleeved on the surface of the top frame 102. Of course, in order to make the sleeve frame 3043 move smoothly along the contour of the top frame 102, rollers or balls can be installed on the contact surface of the sleeve frame 3043 relative to the top frame 102, so that the sleeve frame 3043 is slidably connected to the surface of the top frame 102 through the rollers or balls. The frame 3043 is provided on the inner and outer sides of the breeding box 101 and is respectively connected to the inner roller 306 and the outer roller 305. The outer roller 305 and the inner roller 306 are both composed of an inner central shaft and an elastic rubber cylinder rotatably arranged on the outside of the central shaft. The outer roller 305 and the inner roller 306 are in rolling contact with the breeding box 101 through the cylinder.

[0031] The outer rollers 305 and inner rollers 306 are symmetrically clamped on the outside and inside of the breeding box 101 to reduce the shaking of the breeding box 101. This allows the side net of the breeding box 101 to be constrained and limited by the outer rollers 305 and inner rollers 306, preventing excessive displacement of the net of the breeding box 101 and thus avoiding damage.

[0032] The rest of the structure is the same as in other embodiments.

[0033] Example 4: This embodiment differs from other embodiments in that: like Figures 1-4 As shown, the blocking unit 4 in S3 also includes an extension arm 40321, which is symmetrically fixed to the top of the central platform 301. A mounting bracket 4032 is installed on the top of the extension arm 40321. A take-up reel 4031 is rotatably mounted on one side of the mounting bracket 4032, and a take-up drive source 4033 is fixedly connected to the other side of the mounting bracket 4032. The output shaft of the take-up drive source 4033 passes through the mounting bracket 4032 and connects to the surface of the take-up reel 4031, so that the take-up drive source 4033 drives the take-up reel 4031 to rotate.

[0034] The winding drive source 4033 is preferably a waterproof motor, and the surface of the winding drive source 4033 is covered with a housing.

[0035] like Figures 1-4 As shown, a winding rope 403 is wound around the side of the winding reel 4031. A counterweight ring 402 is fixedly connected to the bottom of the winding rope 403, so that the winding rope 403 pulls the counterweight ring 402 to move up and down inside the breeding tank 101. When the winding rope 403 pulls the counterweight ring 402 away from the water surface of the breeding tank 101, the counterweight ring 402 is taken in. When the winding rope 403 is released, the counterweight ring 402 falls down and presses down on the bottom of the breeding tank 101.

[0036] The winding reel 4031 is composed of a disc and a cylinder in the middle of the disc, and one end of the winding rope 403 is wound around the surface of the cylinder.

[0037] like Figures 1-4 As shown, a movable sleeve 401 extends upward from the top of the counterweight ring 402. Several metal rings are spaced apart on the outer side of the movable sleeve 401. A movable cavity 404 is provided between the movable sleeve 401 and the breeding box 101 to accommodate the movement of the inner roller 306. The material feeding area with the opening at the bottom of the feeding chamber 3041 is located inside the movable sleeve 401.

[0038] The counterweight ring 402 is preferably made of cement, ceramsite, and air bubbler. When the counterweight ring 402 is lowered, it can press against the top of the bottom frame 1011, causing the bottom frame 1011 to move downward under pressure, thus pulling the breeding box 101 straight. The movable sleeve 401 consists of a rubber sleeve and several metal rings on the surface of the rubber sleeve. The metal rings are preferably made of aluminum alloy, so that when the movable sleeve 401 is stored, the multiple aluminum alloy rings overlap, and the rubber sleeves between adjacent rings are folded and stored. When the movable sleeve 401 is unfolded, the multiple aluminum alloy rings hang down, and the rubber sleeves between adjacent rings are stretched. The aluminum alloy rings are located on the outside of the rubber sleeve, thereby reducing the impact of the bass on the aluminum alloy rings when they are feeding on the movable sleeve 401. In addition, the rubber sleeve can reduce the impact of the bass on the aquaculture net when they are feeding, and prevent shellfish attached to the aquaculture net from scratching the bass's body, which could lead to injury, infection and death.

[0039] like Figures 1-4As shown, the collection unit 2 in S4 includes a collection hopper 201 located at the bottom of the breeding box 101 for receiving uneaten feed and cleaning up fallen attachments. A filter chamber 202 is installed at the center of the bottom of the collection hopper 201. A support column 3011 is connected through the middle of the filter chamber 202, and a connecting pipe 203 is provided on the side of the filter chamber 202.

[0040] Operation process: The filter chamber 202 is connected to an external water pump through the connecting pipe 203, so that the external water pump can suck the inside of the filter chamber 202, so that the fallen objects inside the filter chamber 202 and the collection hopper 201, namely the uneaten feed and the attached objects that have fallen off the surface of the breeding box 101, are pumped out by the external water pump.

[0041] The rest of the structure is the same as in other embodiments.

[0042] Detailed operation process: Multiple sets of outer rollers 305 and inner rollers 306 are set inside and outside the breeding box 101. The outer rollers 305 and inner rollers 306 clamp and support the side net of the breeding box 101, reducing the risk of deformation of the net of the breeding box 101. The clamping and support of the breeding box 101 by the outer rollers 305 and inner rollers 306 makes the side net of the breeding box 101 flat, reducing the attachment rate of the relatively loose net to shellfish or algae. That is, the loose net is prone to wrinkles and depressions, providing attachment points for shellfish or algae. When the side net of the breeding box 101 is held by several sets of outer rollers 305 and inner rollers 306, several cables 103 can be movably connected along the outline of the outer side of the bottom frame 1011. The cables 103 pull the bottom frame 1011 and the bottom of the breeding box 101. Then, the extruded floating feed to be fed is placed into the feeding chamber 3041 by hand, which starts the motor inside the rotating part 302, causing the motor inside the rotating part 302 to drive the frustum 303. The rotation of the truncated cone 303 causes the feeding arm 304, connecting arm 3042, and sleeve frame 3043 to rotate along the top frame 102. As the feeding arm 304 rotates, the extruded floating feed rolls downward along the feeding arm 304 at an angle. In conjunction with the rotation of the feeding arm 304, the extruded floating feed inside the feeding chamber 3041 is scattered onto the water surface inside the breeding tank 101 through the opening at the bottom of the feeding chamber 3041, thereby attracting the bass to compete for the extruded floating feed. The area where the expanded floating feed is scattered in the feeding chamber 3041 is located inside the movable sleeve 401. This causes the two winding drive sources 4033 on the symmetrical extension arm 40321 to rotate synchronously under the control of the PLC and encoder. When the winding drive sources 4033 rotate, they drive the winding reel 4031 to rotate, thereby releasing the unwinding rope 403 during rotation. As the unwinding rope 403 is released, the movable sleeve 401, which is folded between the water surface and the extension arm 40321, is gradually released into the aquaculture tank 101. With the release of the unwinding rope 403, the movable sleeve 401 eventually passes through the counterweight ring at its bottom. 402 slowly falls to the bottom of the breeding tank 101, causing the bottom of the breeding tank 101 to be pressed down and stretched. The movable sleeve 401 contacts the bottom of the breeding tank 101 through the counterweight ring 402 at its bottom, making the inside and outside of the movable sleeve 401 relatively closed. The feed thrown by the feeding chamber 3041 is located inside the movable sleeve 401. Thus, during the initial period of feed throwing, after the bass receive the feeding signal that the feed is thrown to the water surface, their concentrated area is located inside the movable sleeve 401. This prevents the bass inside the movable sleeve 401 from accidentally running into the interior of the movable chamber 404, i.e., between the breeding tank 101 and the movable sleeve 401, when the movable sleeve 401 is lowered. When the movable sleeve 401 comes into contact with the rearing tank 101, the feeding area of ​​the sea bass is temporarily closed relative to the side of the rearing tank 101, thereby reducing the impact of seawater flow on the feed, reducing the amount of feed flowing out of the movable sleeve 401, and reducing the ineffective swimming of the sea bass in order to chase the feed that has been washed away. In addition, with the rotating feeding chamber 3041, the sea bass in all positions inside the movable sleeve 401 can be fed, further reducing the ineffective swimming of the sea bass, thereby improving the feeding efficiency.

[0043] As the feeding arm 304 rotates with the truncated cone 303, its outer roller 305 and inner roller 306 roll on the surface of the side net of the aquaculture tank 101, which is being pressed and stretched by the counterweight ring 402. This rubs away any adhering substances on the surface of the side net, improving the cleanliness of the aquaculture tank 101 and extending the interval between cleaning and replacement. This prevents excessive algae from clogging the mesh or shellfish from scratching the fish's skin. Simultaneously, when the outer roller 305 and inner roller 306 are not moving, they also support the aquaculture tank 101, reducing excessive deformation of the net. During this process, the movable sleeve 401 blocks the fish from contacting the aquaculture tank 101, preventing the moving outer roller 305 and inner roller 306 from scratching the fish. Furthermore, the movable sleeve 401 is made of rubber, thus acting as a flexible barrier. It absorbs and reduces the noise and vibration generated during the cleaning process to a certain extent, reducing direct disturbance to the fish. Similarly, the movable sleeve 401 serves as a barrier between the fish and the rearing tank 101. Its bottom is in direct contact with the bottom of the rearing tank 101 without any openings. This allows the movable sleeve 401 to block the debris removed by the outer roller 305 and inner roller 306 from the rearing tank 101, reducing the accumulation of debris in the middle of the rearing tank 101 and its contact with the fish, which could scratch the fish skin or adhere to the fish's surface, increasing the possibility of contamination. After the sea bass are fed, the movable sleeve 401 is pulled back to its original position by the release rope 403, allowing the fish inside the movable sleeve 401 to come into contact with the external environment. This allows the seawater to continue to move the sea bass, enabling them to continue swimming in the flowing seawater and ensuring the quality of the sea bass meat.

[0044] Of course, in order to increase the speed at which the outer roller 305 and inner roller 306 remove the attached material, a water pump can be added to the top of the movable chamber 404, that is, the top of the breeding box 101 and the movable sleeve 401. The water pump outputs water flow to impact the internal space of the movable chamber 404, so that the water flow carries the fallen attached material through the collection hopper 201 into the interior of the filter chamber 202 for collection, which is convenient for subsequent cleaning.

Claims

1. A feeding method specifically for sea bass aquaculture, characterized in that, Includes the following steps: S1. Internal and external support breeding: Multiple sets of outer rollers (305) and inner rollers (306) are set inside and outside the breeding box (101) in the breeding unit (1) so that the outer rollers (305) and inner rollers (306) in the feeding unit (3) clamp and support the side net of the breeding box (101); S2, Rotary feeding: By placing the extruded floating feed to be fed onto the top of the feeding chamber (3041) inside the feeding arm (304), the feeding arm (304) rotates, causing the feeding chamber (3041) to rotate on the top of the breeding tank (101), so that the feed is rotated and scattered onto the water surface inside the breeding tank (101) through several openings at the bottom of the feeding chamber (3041); S3, Movable blocking: When the feeding arm (304) rotates, the movable sleeve (401) in the blocking unit (4) is lowered and unfolded, so that the movable sleeve (401) is isolated between the feed feeding area and the breeding box (101). The downward movement of the movable sleeve (401) will press the counterweight ring (402) at its bottom down to the bottom of the breeding box (101), so that the breeding box (101) is pressed down and stretched, so that the bass have enough room to move. S4. Feeding and cleaning: While the feeding arm (304) is rotating, it will drive the outer roller (305) and inner roller (306) to roll on the side net surface of the stretched breeding box (101), so that the attached objects on the side net surface of the breeding box (101) are rolled and cleaned. The bottom of the movable sleeve (401) is in contact with the bottom of the breeding box (101) through the counterweight ring (402), thereby preventing the attached objects that have fallen off from entering the feed distribution area inside the movable sleeve (401). After the feeding and cleaning is completed, the movable sleeve (401) is raised and reset, so that the seawater outside the movable sleeve (401) enters the feed distribution area.
