Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and in particular to a low-feeding aquaculture system based on the control and utilization of Cranaria officinalis. Background Art

[0002] In current sea cucumber and shrimp aquaculture, pond water quality can easily reach two extremes: excessive fertility in the middle and late stages of aquaculture, resulting in high turbidity and drastic water quality fluctuations, leading to low seedling survival rates; and excessive leanness in the water, which can lead to explosive growth of filamentous algae, Enteromorpha, and Scutellaria spp., encroaching on the habitats and feeding areas of the aquatic species in the mid-stage of aquaculture. When water temperatures rise, these algae die in large numbers, further deteriorating water quality. However, nutrients (i.e., water with a certain fertility level) and benthic macroalgae are essential in aquaculture environments, playing a crucial role in maintaining water stability and promoting the growth of aquatic animals. A certain fertility level in water promotes the growth and diversity of aquatic biomass and inhibits the overgrowth of macroalgae. A certain amount of benthic macroalgae in aquaculture water stabilizes the sediment, reduces sediment disturbance caused by wind and waves, promotes the deposition of leftover bait and feces, absorbs excess nutrients, and provides diverse habitats for microorganisms, further increasing the amount of feeding and shelter for aquatic animals. In view of this, the purpose of the present invention is to establish a three-dimensional aquaculture model for the ecological polyculture of ginseng and shrimp without feeding, and the feeding of grouper or puffer fish in cages, taking the common benthic macroalgae Sichuan algae type ponds in coastal areas as a representative, and utilize the low-feeding measures of the system and the excretion of the predatory cultured species to moderately increase the fertility of the water body. Through the existence of the overall equipment and the implementation of relevant aquaculture technologies, a low-feeding aquaculture system based on the control and utilization of Sichuan algae is provided to solve the shortcomings of the existing technology.

[0014] The present invention provides a low-feeding aquaculture system based on the control and utilization of Sichuan algae.

[0015] Beneficial effects:

[0016] 1. The present invention connects the hull to a fixed anchor in the pond via a steel cable, and utilizes the tension of the steel cable and the anchoring effect of the fixed anchor to stabilize the hull in a designated position. Simultaneously, a motor drives the impeller, and an air pump sprays air to create a directional water flow. This achieves the technical effect of creating a directional water flow in the pond, promoting the sedimentation of leftover bait and feces in a designated area, achieving pond water circulation, purifying water quality, and creating a favorable aquaculture ecological environment. Compared with the existing technical solutions that may have poor pond water flow and nutrient circulation and untimely water purification, this solves the problems of easy diffusion of leftover bait and feces in the water, easy deterioration of local water quality, and unstable aquaculture ecological environment.

[0017] 2. This invention employs a lifting assembly consisting of a hoist, ropes, a fixing frame, and connecting ropes positioned above the cage. A controller controls the hoist to raise and lower the cage. This allows the cage to be lifted during rainy weather, allowing the cultured organisms to receive a freshwater bath for disease prevention or treatment, thereby reducing medication usage and promoting healthy farming. Compared to existing solutions that may lack the flexibility to adjust the cage position and utilize natural conditions for disease control, this solution addresses the limitations of limited disease control methods, high medication requirements, and challenges associated with healthy farming. It also simplifies the net-catching operation, saving significant manpower.

[0018] 3. The present invention employs a feeding assembly consisting of an electric slide, an electric slider, a fixed block, an electric push rod, a feeding machine, and a feeding tube, which is installed on an operating table. By controlling the electric slide, the electric push rod, and the feeding tube to feed the fish at a short distance close to the water surface, the present invention achieves a technical solution for accurately feeding the fish cages. This achieves the technical effect of accurately feeding each fish cage in sequence, improving feeding efficiency and accuracy. Compared with the existing technical solutions that may have problems such as inconvenient feeding operation, inaccurate feeding position, feed dispersion, and gulls snatching food, which result in significant feed waste, this solution solves the shortcomings of low feeding efficiency, low feed utilization rate, and increased breeding costs.

[0019] 4. The present invention employs a detection assembly consisting of a connecting plate, support rods, a mounting plate, and a temperature sensor mounted on the inner wall of the support frame, and a sunshade assembly consisting of a sunshade net, a fixing rope, a hoist, a connecting seat, a winding roller, a connecting shaft, and a motor mounted on the upper side of the cage. The temperature sensor detects water temperature and controls the deployment or retraction of the sunshade net. This achieves the technical effect of real-time water temperature detection, automatically adjusting the sunshade net according to the appropriate water temperature for the aquaculture species, and providing a suitable lighting environment for the aquacultured organisms. Compared to existing technical solutions that may be unable to monitor water temperature in real time and flexibly adjust the aquaculture environment according to water temperature changes, this solves the shortcomings of existing technologies that have inaccurate aquaculture environment control and are not conducive to the growth of aquacultured organisms.

[0020] 5. The leftover bait and feces produced by feeding grouper or puffer in the present invention can provide bait for ginseng and shrimp. The coverage of the sediments such as the leftover bait and feces can inhibit the photosynthesis of the cribriformis to a certain extent, thus preventing its over-reproduction. The soluble nutrients produced can stimulate the reproduction of algae in the water body, so that the water body maintains a certain fertility and inhibits the over-reproduction of the cribriformis. Part of the excrement of fish, shrimp and ginseng can be absorbed and utilized by the cribriformis, and the deposited algae and dead cribriformis can be used as bait for ginseng and shrimp. In short, the addition of cage feeding aquaculture avoids the explosive growth, sudden death or excessive thinness or fatness of the cribriformis, and promotes the formation of a self-purification cycle balance in the aquaculture water body. In the system, only the farmed fish are fed, which realizes the low-feeding strategy and resource recycling of the entire system. In addition, the introduction of farmed species such as ginseng, shrimp, grouper or puffer achieves the comprehensive and effective utilization of space, and greatly improves the aquaculture output and output.

[0021] 6. The present invention effectively limits the expansion of the R. chuanxiensis by providing shelter from the net cages and sunshade nets, covering the remaining bait and feces, feeding by ginseng and shrimp, and competition among microalgae for nutrients. Nutrients released from the remaining bait and feces, circulating water flow, and appropriate local illumination can maintain a stable and long-term biomass of the R. chuanxiensis, purifying the water quality. This achieves the control and utilization of the R. chuanxiensis.

[0022] 7. The four cage systems described in the present invention are suitable for being arranged on the north side of the pond where the cribriformis grows densely to maximize their effectiveness; they can be used as a unit and expanded according to the shape and area of the pond.

[0023] 8. The present invention is also applicable to ponds before the infestation of other large benthic algae such as Cladophora and Enteromorpha. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Please see the attached Figure 1 -Attached Figure 7, an embodiment of the present invention provides; a low-feeding aquaculture system based on the control and utilization of Sichuan algae, including a pond 1, an operating table 2 is fixedly installed inside the pond 1, an air-pumping water-pushing component 20 is provided inside the operating table 2, the air-pumping water-pushing component 20 includes an air pump 201, the air pump 201 is installed on the upper side of the operating table 2, the left side of the air pump 201 is fixedly connected to an air intake pipe 204, the side of the air pump 201 away from the air intake pipe 204 is fixedly connected to a connecting pipe 202, the front side of the connecting pipe 202 is fixedly installed with an air jet pipe 203, the front side of the air jet pipe 203 is fixedly connected There is a fixed pipe 205, and a plurality of spray holes 206 are opened inside the fixed pipe 205. Four frames 22 are fixedly installed on the front side of the operating platform 2. The inside of the frame 22 is provided with a net cage 3. The upper side of the net cage 3 is provided with a lifting component 13. The upper side of the operating platform 2 is provided with a bait throwing component 4. The side of the operating platform 2 away from the net cage 3 is provided with hull 1 7, hull 2 8 and hull 3 9. The hull 1 7, hull 2 8 and hull 3 9 are arranged on the rear side of the operating platform 2 in order from left to right. The hull 1 7, hull 2 8 and hull 3 9 are all provided with a fixing component 12. The fixing component 12 includes a steel cable 121, which is fixedly connected to hull 1 7, hull 2 8 and hull 3 9. A fixed anchor 122 is fixedly connected to the side of the steel cable 121 away from hull 1 7, hull 2 8 and hull 3 9. The fixed anchor 122 is fixedly connected to the inside of the pond 1. The upper sides of hull 1 7 and hull 3 9 are fixedly connected to a fixing rod 116. The impeller shaft 114 is rotatably connected to the inside of the fixing rod 116. The upper side of hull 2 8 is fixedly connected to a fixing seat 10. The interior of the fixing seat 10 is provided with a drive assembly 11. The drive assembly 11 includes a motor 111. Motor 111 is fixedly connected to the inside of the fixing base 10, and the output end of motor 111 is fixedly connected to gear 112, and the lower side of gear 112 is meshedly connected to gear 2 113, and the inside of gear 2 113 is fixedly connected to an impeller shaft 114, and the outer side of the impeller shaft 114 is fixedly connected to four impellers 115. The left side of the pond 1 is fixedly connected to support frame 17, and the inner wall of support frame 17 is provided with a detection component 14. The right side of the pond 1 is fixedly connected to support frame 2 18, and the upper sides of support frame 17 and support frame 2 18 are provided with a sunshade component 19;

[0038] Specifically, the hull 1 7, the hull 2 8 and the hull 3 9 are tightly connected to the fixed anchor 122 fixed inside the pond 1 through the steel cable 121, and the fixed anchor 122 is deeply embedded in the bottom of the pond 1. By virtue of its own weight and the friction between the barb and the bottom of the pond, it provides a stable anchoring effect for the hull. Under the combined influence of the tension of the steel cable 121 and the anchoring effect of the fixed anchor 122, the hull can stay stably in the designated position. The distance between the hull and the operating platform 2 is 5 to 8 meters. The length of the frame 22 and the cage 3 is preferably 12 meters, the width of the frame 22 and the cage 3 is preferably 5 meters, and the spacing between adjacent frames 22 is preferably The hull is 0.5 meters. When the hull is stably in place, the motor 111 in the fixing seat 10 is started. After the motor 111 is started, its output end starts to rotate at high speed, driving the gear 112 connected thereto to rotate synchronously. Since the gear 112 and the gear 2 113 are in a meshing state, according to the principle of gear transmission, the rotation of the gear 112 will accurately drive the gear 2 113 to rotate, and the rotation of the gear 2 113 will drive the impeller shaft 114 fixedly connected thereto to rotate, thereby causing the four impellers 115 outside the impeller shaft 114 to start rotating. During the rotation of the impeller 115, the impeller 115 exerts pressure on the surrounding water. The air pump 201 also starts to work. The air pump 201 continuously inhales air through the air inlet pipe 204, sucks the outside air into the air pump 201 and compresses it. The compressed gas has a high pressure and is transported to the air jet pipe 203 through the connecting pipe 202. The gas is ejected at a high speed from the nozzle 206 of the fixed pipe 205 on the front side of the air jet pipe 203, and acts on the water in the cage 3 with a strong impact force. Under the joint action of the impeller 115 and the gas ejected from the air jet pipe 203, the water in the cage 3 forms a directional water flow, which can make the cage Driven by the water flow, the remaining bait and feces in 3 are smoothly settled in the designated sedimentation area, avoiding the random diffusion of the remaining bait and feces in pond 1, thereby keeping the water quality of pond 1 clean. At the same time, the directional water flow promotes the circulation of water in the entire pond 1, and timely exchanges the purified water in the Sichuan algae area with the nutrient-rich water in pond 1. During its growth, Sichuan algae can absorb nitrogen, phosphorus and other nutrients in the water body, which plays a role in purifying the water quality, and the nutrient-rich water provides the necessary nutrients for the growth of Sichuan algae. Through this water circulation, living water is formed in pond 1, creating a good ecological environment for aquaculture.

[0039] Please see the attached Figure 1 -Attached Figure 2 , a pond slope 5 is provided on the front side of the cage 3, an aquatic plant cultivation area 16 is provided on the upper side of the pond slope 5, a pond bottom 6 is fixedly connected to the left side of the pond slope 5, and a sedimentation area 15 is provided on the upper side of the pond bottom 6;

[0040] Specifically, in terms of aquaculture species, in order to address the problem of idle resources due to the summer hibernation "window period" in sea cucumber farming, species such as grouper and Chinese shrimp were introduced for mixed farming. This mixed farming model fully utilizes time and space resources. Fish such as grouper and pufferfish have the characteristics of fast growth and wide temperature adaptability. They are farmed in cages 3. During the farming process, the leftover bait, feces and excrement produced by the fish will settle into the sedimentation area 15 of the pond bottom 6, while the aquatic plant cultivation area 16 on the pond slope 5 is planted with Sichuan algae. Sichuan algae can absorb the nutrients in these leftover bait, feces and excrement to achieve self-purification cycle. Under such a farming model, ginseng and shrimp do not need to be fed with additional feed, because Sichuan algae is not only easy to obtain, but also has a strong absorption capacity for nitrogen and phosphorus, and can increase the food source of ginseng and shrimp.

[0041] Please see the attached Figure 2 -Attached Figure 4 The lifting assembly 13 includes a hoist 131, which is fixedly connected to the inner walls of the support frame 17 and the support frame 2 18. A rope 133 is wound around the inside of the hoist 131, and one end of the rope 133 away from the hoist 131 is fixedly connected to a fixing frame 134. The lower side of the fixing frame 134 is fixedly connected to a connecting rope 132, and the connecting rope 132 is fixedly connected to the four corners of the upper side of the net box 3;

[0042] Specifically, when it is necessary to lift the cage 3, when it rains, due to the low density of rainwater, it will gather on the surface of the pond 1. At this time, the controller 21 controls the winch 131 to start, and the winch 131 starts to retract and release the rope 133. The movement of the rope 133 drives the fixed frame 134 to rise or fall. The fixed frame 134 is connected to the cage 3 through the connecting rope 132, thereby realizing the lifting of the cage 3. After lifting the cage 3, a pulley can be added on both sides as needed to assist in lifting the cage 3. The cultured organisms can receive a freshwater bath on the surface of the pond 1, which is helpful for disease prevention or treatment. In addition, the breeders can also choose to artificially sprinkle fresh water to further achieve the goal of reducing the use of medicines and healthy breeding.

[0043] Please see the attached Figure 5 The bait throwing assembly 4 includes an electric slide rail 41, which is fixedly connected to the upper side of the operating table 2. An electric slider 42 is slidably connected to the interior of the electric slide rail 41. A fixed block 43 is fixedly connected to the upper side of the electric slider 42. An electric push rod 44 is fixedly connected to the front side of the fixed block 43. A telescopic end of the electric push rod 44 is fixedly connected to a bait throwing machine 45. A feeding pipe 46 is fixedly connected to the lower side of the bait throwing machine 45.

[0044] Specifically, when it is necessary to feed the farmed organisms, the operator can start the electric slide 41 on the control console 2, and the electric slider 42 slides smoothly along the track inside the electric slide 41, driving the fixed block 43 to move left and right. At the same time, the electric push rod 44 is started, and the electric push rod 44 performs telescopic movement back and forth. The feeding machine 45 is installed at the telescopic end of the electric push rod 44. With the movement of the electric slider 42 and the electric push rod 44, the feeding machine 45 can accurately reach the top of each net cage 3, and the feed stored in the feeding machine 45 is delivered to the net cage 3 through the discharge pipe 46, so that each net cage 3 is accurately fed in turn.

[0045] Please see the attached Figure 8 -Attached Figure 11 The detection component 14 includes a connecting plate 142, which is fixedly connected to the operating table 2. The lower side of the connecting plate 142 is fixedly connected to a support rod 143, and the lower side of the support rod 143 is fixedly connected to a mounting plate 144. The lower side of the mounting plate 144 is fixedly installed with a temperature sensor 141, and the rear side of the temperature sensor 141 is fixedly installed with a PH sensor 145, and the rear side of the PH sensor 145 is fixedly installed with a DO probe 146; the sunshade component 19 includes a sunshade net 191, the sunshade net 191 is installed on the upper side of the net box 3, and the left side of the sunshade net 191 is fixedly connected with a fixing rope 193, and the upper side of the support frame 17 is fixedly installed with two winches 192, and the winches 192 A winding rope 198 is wound around the inside, and a fixing rope 193 is fixedly connected to the winding rope 198. A connecting seat 194 is fixedly connected to the upper side of the supporting frame 18. A winding roller 195 is provided inside the connecting seat 194. A connecting shaft 197 is fixedly connected to the inside of the winding roller 195. A motor 2 196 is fixedly installed on the rear side of the connecting seat 194. The motor 2 196 is fixedly connected to the connecting shaft 197. A controller 21 is fixedly installed on the inner wall of the supporting frame 17. The controller 21 is electrically connected to the electric slide rail 41, the motor 111, the winch 131, the temperature sensor 141, the pH sensor 145, the DO probe 146, the winch 2 192, the motor 2 196 and the air pump 201.

[0046] Specifically, during the breeding process, a connecting plate 142 is installed on the upper right side of the operating table 2, and the connecting plate 142 is connected to the mounting plate 144 through a support rod 143. The temperature sensor 141 at the bottom of the mounting plate 144 detects the temperature of the water in the pond 1 in real time and accurately transmits the detected temperature data to the controller 21. The breeding personnel can make timely adjustments to the breeding environment according to the temperature changes. When the breeding species is pufferfish and the water temperature exceeds 28°C, or the breeding species is grouper and the water temperature exceeds 30°C, in order to avoid the adverse effects of high temperature on the breeding organisms, the system will automatically pull up the sunshade net 191. When the sunshade net 191 is pulled up, the controller 21 controls the motor 2 196 to reverse, and the reversal of the motor 2 196 drives the connecting shaft 197 and the winding roller 195 to rotate, winding the fish. The sunshade net 191 wound on the winding roller 195 is gradually released. At the same time, the controller 21 controls the winch 192 to release the winding rope 198, and the fixed rope 193 connects the sunshade net 191 and the winding rope 198 together, assisting the sunshade net 191 to unfold smoothly, so that it covers the upper side of the cage 3, providing a suitable lighting environment for the cultured organisms, and reducing the impact of water temperature on the cultured organisms. When the water temperature drops and the sunshade net 191 is no longer needed, the motor 196 rotates forward to reel up the sunshade net 191, and the winch 192 retracts the winding rope 198 at the same time, assisting the sunshade net 191 to complete the winding operation. At the same time, the PH sensor 145 can check the PH value of the pond 1, and the DO probe 146 can measure the dissolved oxygen content in the pond water 1, which will be reflected on the display screen of the controller 21 for easy observation.

[0047] Working principle: When using this device, hull 1 7, hull 2 8 and hull 3 9 are connected to the fixed anchor 122 fixed inside the pond 1 through the steel cable 121. The tension of the steel cable 121 and the anchoring effect of the fixed anchor 122 are used to stabilize the hull in the specified position. Then, the motor 111 in the fixed seat 10 is started. After the motor 111 is started, its output end drives the gear 112 to rotate. Since the gear 112 is engaged with the gear 2 113, the gear 11 The rotation of 2 will drive the gear 2 113 to rotate, and the gear 2 113 will drive the impeller shaft 114 to rotate, and then drive the four impellers 115 on the outside to rotate. At the same time, the air pump 201 sucks air through the air inlet pipe 204, and transmits the compressed gas to the jet pipe 203 through the connecting pipe 202. The gas is ejected at high speed from the nozzle 206 of the fixed pipe 205 on the front side of the jet pipe 203, exerting force on the water in the pond 1, pushing the water to flow and form a directional water flow, which is beneficial to the removal of residual bait and feces. Sedimentation in the designated sedimentation area is beneficial to the circulation of water in the entire pond 1, and the purified water in the Sichuan algae area and the nutrient-rich water in the pond 1 are exchanged in time to form living water, creating a good aquaculture ecological environment. In sea cucumber aquaculture, its summer dormancy "window period" causes idle resources. For this reason, grouper, Chinese shrimp, etc. are introduced for mixed culture to make full use of time and space resources. Grouper, puffer fish and other fish grow fast and have a wide temperature adaptability. They are cultured in cages 3. During the aquaculture, the remaining bait, feces and excrement of the fish are deposited into the sedimentation area 15 of the pond bottom 6, and form a self-purification cycle with the Sichuan algae planted in the aquatic plant cultivation area 16 on the pond slope 5. The sea cucumbers and shrimps grow by eating the feces produced by the cage 3 aquaculture and the biological bait in the pond 1 without feeding. The system forms a low-feeding technology. Relying on the characteristics of the widely distributed and easily accessible large algae represented by Sichuan algae, which have a strong ability to absorb nitrogen and phosphorus in the water body, which is beneficial to increasing the biomass and diversity of bait in the aquaculture environment, an ecological aquaculture system is formed.

[0048] When feeding is needed, the operator can start the electric slide 41 on the control console 2, and the electric slider 42 slides inside the electric slide 41, and the electric slider 42 drives the fixed block 43 to move left and right, and at the same time starts the electric push rod 44 to extend and retract forward and backward, and the feed in the feeding machine 45 is fed into the net cage 3 through the feeding pipe 46, and each net cage 3 is fed in turn;

[0049] The temperature of the water in the pond 1 is detected in real time by the temperature sensor 141, and the temperature data is transmitted to the controller 21. The breeder can automatically pull up the sunshade net 191 according to the temperature change when the fish is pufferfish (water temperature exceeds 28°C) or grouper (water temperature exceeds 30°C). When the sunshade net 191 needs to be unfolded, the controller 21 controls the motor 196 to reverse, drive the connecting shaft 197 and the winding roller 195 to rotate, and release the sunshade net 191 from the winding roller 195. At the same time, the controller 21 controls the motor 196 to rotate. The second winch 192 releases the reeling rope 198, and the fixed rope 193 connects the sunshade net 191 and the reeling rope 198, which helps the sunshade net 191 to be unfolded and covered on the upper side of the cage 3, providing a suitable lighting environment for the cultured organisms; when the sunshade net 191 needs to be retracted, the second motor 196 rotates forward to reel in the sunshade net 191, and the second winch 192 retracts the reeling rope 198 to assist in the operation. At the same time, the pH sensor 145 can check the pH value of the pond 1, and the DO probe 146 can measure the dissolved oxygen content in the water of the pond 1;

[0050] When it is necessary to lift the net cage 3, the controller 21 controls the winch 131 to start, the winch 131 retracts and releases the rope 133, the rope 133 drives the fixed frame 134 to rise or fall, and the fixed frame 134 is connected to the net cage 3 through the connecting rope 132, thereby realizing the lifting and lowering of the net cage 3. When it rains, the net cage 3 is lifted, and the density of rainwater is low and gathered on the surface of the pond 1, so that the cultured species can be bathed in fresh water to prevent or treat diseases. Fresh water can also be artificially sprinkled to achieve healthy breeding with reduced medication, and it also makes it simple and easy to catch the fish in the net.

[0051] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
