Description

Technical Field

[0001] This invention belongs to the field of marine ecological fishery carbon sink monitoring technology, specifically relating to a marine ranch ecological fishery carbon sink data acquisition device. Background Technology

[0002] Marine ranching is an important model for achieving sustainable utilization of fishery resources and ecological restoration, as it can generate significant carbon sinks through large-scale aquaculture activities. Accurate monitoring and assessment of this carbon sink process is crucial for developing a blue carbon economy and quantifying the ecological benefits of aquaculture.

[0003] Currently, relevant monitoring largely relies on independent and decentralized sampling and measurement. Carbon sequestration data is typically acquired through fixed-point, intermittent water sampling and laboratory analysis, making it difficult to achieve continuous and synchronous monitoring of the spatiotemporal dynamics of carbon sequestration within aquaculture areas. Furthermore, observations of fish behavior, distribution, and environmental factors (such as ocean currents) are often separated from carbon sequestration monitoring, making it difficult to reveal the coupling mechanisms between biological activity and environmental drivers on carbon sequestration formation. At the aquaculture management level, operations such as feeding rely heavily on experience, lacking precise control based on real-time environmental and biological feedback. This can not only lead to feed waste but also affect the stability of carbon sequestration due to undue disturbance.

[0004] Therefore, existing technologies suffer from problems such as sparse monitoring points, limited data dimensions, and inefficient management and control, which hinder a deeper understanding and efficient management of the carbon sequestration mechanism in marine ranches. There is an urgent need for an integrated device capable of multi-parameter, three-dimensional, synchronous monitoring and intelligent feedback control based on data. Summary of the Invention

[0005] The present invention aims to provide a data acquisition device for carbon sinks in marine ranching ecological fisheries, in order to solve the problems of isolated monitoring data and extensive management in the existing technology, thereby achieving efficient collection of carbon sink data and precise optimization of aquaculture management.

[0006] A marine ranch ecological fishery carbon sequestration data acquisition device includes a buoy, with a culture cage installed below the buoy. The bottom of the culture cage is anchored to the seabed by ropes. The device is characterized by ropes evenly distributed around the perimeter of the culture cage along the bottom edge of the buoy. Floats are installed at equal intervals along the height direction on the ropes, and each float is equipped with a current meter. An integrated box is installed at equal intervals along the height direction on the sidewall of the culture cage, in the same manner as the floats. The integrated box houses a carbon sequestration measurement device, a feeding device, and a fish finder. This invention is used to collect water carbon sequestration data at different locations in marine ranches. The buoy provides the main buoyancy for the device, ensuring its stable floating on the sea surface. The anchor is connected to the bottom of the culture cage via ropes, maintaining the stability of the entire device in wind, waves, and strong currents. The floats surrounding the culture cage are all equipped with current meters, which can detect wave and current velocities in all directions around the culture cage in real time. Each float is equipped with an integrated box on the side wall of the aquaculture cage. The box contains a carbon sink measurement device, a feeding device, and a fish finder, which are used to monitor the carbon sink content in the area, to feed or release attractants to attract fish when necessary, and to detect fish aggregation.

[0007] A marine ranching ecological fishery carbon sequestration data acquisition device is characterized by an opening in the central area of ​​the top of the buoy for feeding and releasing fish. The opening's central location on the top of the buoy facilitates feeding, releasing, and harvesting operations. This structure allows for centralized and efficient feeding and harvesting operations, reducing disturbance to fish in the aquaculture cages and facilitating fixed-point management by personnel or automated equipment.

[0008] A marine ranching ecological fishery carbon sequestration data acquisition device is characterized by a measuring rope suspended vertically from the center of the opening, with carbon sequestration measuring devices installed at equal intervals along the same vertical direction as the floats. By arranging the carbon sequestration measuring devices at equal intervals along the vertical direction of the measuring rope suspended vertically from the center of the opening, a continuous monitoring line is formed running through the water body. This design can simultaneously acquire carbon sequestration data at different water depths at the center of the aquaculture cage, facilitating comparative analysis of the vertical distribution characteristics of carbon sequestration. Furthermore, it forms a coordinated three-dimensional monitoring network with the integrated boxes on the outer sidewalls of the aquaculture cages, further enhancing the comprehensiveness and spatial resolution of data acquisition.

[0009] A data acquisition device for carbon sequestration in marine ranching ecological fisheries is characterized by a weather station mounted on the top surface of the pontoon. This weather station detects wind speed, wind direction, air pressure, rainfall, and photosynthetically active radiation (RALED). Integrated into the top of the pontoon, the weather station can monitor multi-dimensional meteorological parameters such as wind speed, wind direction, air pressure, rainfall, and RLED in real time. This design enables simultaneous acquisition of meteorological conditions above the aquaculture environment, providing direct data support for analyzing the impact of meteorological factors on the carbon sequestration process. It also helps establish a correlation model between carbon sequestration changes and meteorological fluctuations, thereby improving the systematic nature and interpretability of carbon sequestration monitoring.

[0010] A marine ranch ecological fishery carbon sink data acquisition device is characterized by including a control unit. This control unit is communicatively connected to the current meter, carbon sink measurement device, feeding device, and fish finder, respectively. It receives and processes data collected by each device and controls the start / stop and feeding position of the feeding device according to a preset strategy. By setting up a control unit communicatively connected to the current meter, carbon sink measurement device, feeding device, and fish finder, multiple previously independently operating detection and execution devices are integrated into a unified intelligent monitoring and control system. This design achieves centralized acquisition, processing, and analysis of environmental data (waves, carbon sinks, fish schools), and can automatically control the start / stop and position of feeding operations according to a preset strategy, thereby significantly improving the synergy of data acquisition, the scientific nature of management decisions, and the automation and precision of aquaculture control.

[0011] A marine ranch ecological fishery carbon sequestration data acquisition device, characterized in that the control unit is configured as follows: Based on the wave velocity data detected by current meters in various directions, identify the fast-flow and slow-flow areas around the aquaculture cages; Based on the fish distribution data detected by the fish finder, combined with information on the rapid and slow current zones, a feeding control command is generated. The system controls the feeding device to attract fish and deliver food to areas with slow currents or sparse fish populations, guiding the fish to gather in suitable areas. The control unit, by integrating wave data from a current meter, can identify fast and slow current zones around the aquaculture cages in real time and generate intelligent control strategies based on fish distribution data from a fish finder. On this basis, the system can control the feeding device to perform precise feeding in stages: when fast currents occur, a special attractant is released first into the target slow current zone to guide the fish to gather in suitable areas; after the fish have gathered, food is then delivered for concentrated feeding, thereby improving feeding efficiency and reducing food loss. After the fast current subsides, the system can gradually resume the regular feeding mode, prompting the fish to redistribute naturally within the aquaculture cages. This design, through a proactive control mechanism of "induction first, then feeding, and then equalization," achieves effective management of fish distribution and feeding behavior in dynamic ocean current environments, providing behavioral-level technical support for optimizing aquaculture structure and improving the stability of carbon sink formation. As described in the Global Alliance for Rewilding and Regeneration's article "Fish: The excretion effect boosts the oceanic carbon pump," fish are key bio-drivers in aquaculture ecosystems. Their feeding behavior accelerates the conversion and transfer of carbon contained in primary producers such as phytoplankton in water bodies; their excrement (especially fecal particles floating in the ocean) is an important carrier of the ocean's "biological carbon pump." Studies have shown that the carbon flux from farmed fish fecal particles is considerable, and its settling rate and stability are influenced by the intensity of fish activity, distribution, and environmental hydrodynamic conditions. Furthermore, the system can analyze the spatial coupling relationship between fish distribution hotspots and high carbon sink concentrations, identifying potential carbon sink advantage zones (such as slow-flowing areas). When fish populations are sparse, they are guided to gather in these areas to enhance bio-driven carbon sink processes. When strong currents are detected as potentially causing carbon resuspension, fish are guided away from highly disturbed areas to reduce disturbance to already fixed carbon. When a certain water layer has a low carbon sink concentration, stratified feeding is used to guide fish to increase activity in that layer, stimulating the carbon sink potential of the entire water body.

[0012] A marine ranch ecological fishery carbon sequestration data acquisition device, characterized in that the control unit is further configured as follows: Collect carbon sequestration data from the carbon sequestration measurement device in real time or at regular intervals; Link and store carbon sink data, fish distribution data, ocean current speed data, and feeding records; A correlation model was established based on historical data to link carbon sink levels with fish aggregation and ocean current flow. The control unit collects monitoring data from various carbon sink measurement devices in real-time or at set intervals, enabling continuous and synchronous recording of carbon sink levels in different areas inside and outside the aquaculture cages. More importantly, the system can spatially and temporally correlate and integrate carbon sink data with corresponding fish distribution, ocean current velocity, and feeding records, constructing a multi-parameter coupled aquaculture environment database. Based on this database, a quantitative correlation model can be further established through data analysis between carbon sink changes and fish aggregation status, ocean current dynamics, and feeding management. This design not only upgrades carbon sink monitoring from single data collection to multi-source information fusion but also provides a data foundation and analytical methods for revealing the biological and hydrological coupling mechanism of carbon sink formation and assessing the impact of aquaculture activities on carbon sinks, strongly supporting scientific and model-based ecological fisheries carbon sink management.

[0013] A data acquisition device for carbon sequestration in marine ranching ecological fisheries is characterized by an integrated box divided into upper, middle, and lower zones along the height of the aquaculture cage. Each zone has at least six measurement positions evenly distributed along its circumference, enabling three-dimensional data acquisition. By dividing the float and integrated box into upper, middle, and lower layers along the height of the aquaculture cage, and evenly arranging at least six measurement positions along the circumference of each layer, a three-dimensional gridded monitoring system is constructed. This structure enables simultaneous, high-density data acquisition of the water inside and around the aquaculture cage in both vertical and horizontal directions, significantly improving the spatial resolution and coverage of the monitoring. This arrangement not only more accurately reflects the spatial heterogeneity of parameters such as carbon sequestration, fish populations, and ocean currents, but also provides a reliable data foundation for analyzing the three-dimensional coupling relationship between environmental factors and carbon sequestration formation, thus comprehensively supporting the refined assessment and management of carbon sequestration processes in marine ranching.

[0014] A marine ranch ecological fishery carbon sequestration data acquisition device is characterized in that the top of the buoy is provided with at least one feeding port, the feeding port is connected to the feeding channel around the aquaculture cage, the feeding channel is divided into a first vertical pipe, a second vertical pipe, and a third vertical pipe, the first vertical pipe, the second vertical pipe, and the third vertical pipe are connected by a horizontal pipe, the horizontal pipe is provided with at least two pumps, which are respectively used to transport feed from the first vertical pipe to the second vertical pipe or the third vertical pipe, the first vertical pipe, the second vertical pipe, and the third vertical pipe are all provided with feed inlet pipes connected to feed dispensing devices, and each feed inlet pipe is provided with an electrically controlled shut-off valve at the connection between the vertical pipe and the feed inlet pipe, which is used to supply feed to the corresponding feed dispensing device.

[0015] Referring to the attached diagram, the integrated tank is composed of a carbon sink measuring device, a feeding device, and a fish finder. The feed pipe is directly connected to the feeding device, and a suction pump is installed between the feeding device and the feed pipe to draw bait from the feed pipe into the feeding device. By adjusting the opening and closing of each shut-off valve (the shut-off valve opens to allow bait to pass through, while closing it blocks the bait), the operation of each pump can directly deliver bait from the feeding port at the top of the float into the designated integrated tank, achieving rapid bait replenishment. Referring to the attached diagram, taking the first integrated tank needing bait replenishment as an example, the bait is fed into the first vertical pipe from the feeding port and blocked by the third shut-off valve. The first pump draws the bait from the first vertical pipe into the second vertical pipe. At this time, the second and fourth shut-off valves open, and the first shut-off valve closes. The bait falls directly into the feed pipe connected to the first integrated box due to gravity. The suction pump inside the first integrated box draws in the bait for replenishment. This system enables centralized delivery and independent replenishment of bait to each integrated box, significantly improving the flexibility and efficiency of bait preparation and ensuring continuous and reliable feeding capabilities. Similarly, other integrated boxes can be replenished by controlling the stop valves and the operation of the first and second suction pumps.

[0016] A marine ranch ecological fishery carbon sequestration data acquisition device is characterized by a solar panel covering the top of the buoy. This solar panel provides a continuous and stable green energy supply to the device's weather station and control unit, among other electronic equipment. This design achieves energy self-sufficiency for the monitoring system in the marine environment, significantly reducing reliance on external power supplies or frequent battery replacements. This ensures long-term, continuous data acquisition capabilities and enhances the operational reliability and environmental adaptability of the entire carbon sequestration monitoring device.

[0017] This invention constructs a three-dimensional monitoring network surrounding the aquaculture cages, integrating multi-dimensional sensors such as carbon sink measurement, fish school detection, and wave and current velocity monitoring. This enables high-resolution, synchronized data acquisition of the carbon sink formation process in marine ranches. Furthermore, by leveraging an intelligent control unit to fuse and analyze environmental and biological data, it proactively adjusts feeding locations and strategies, guides fish distribution, and optimizes feeding behavior. This improves the precision of aquaculture management and feed utilization while enhancing the stability and observability of carbon sink formation. It achieves a closed loop from data acquisition to management and control, promoting the systematic, intelligent, and model-based development of ecological fishery carbon sink monitoring and management.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0022] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Example 1: This embodiment provides a data acquisition device for carbon sinks in marine ranching ecological fisheries. Its core lies in the synergy of a three-dimensional monitoring network and an intelligent feedback control system to achieve refined management and proactive optimization of the carbon sink formation environment and biological processes.

[0024] See attached document Figure 1 , 2 As shown, the main body of the device includes a buoyancy-providing float 1 and an aquaculture cage 2 suspended below it, which is stably anchored by a bottom anchor 62. The device constructs a high-resolution three-dimensional sensing network. The solar panel 13 on top of the float 1 provides a continuous and stable green energy supply for the weather station 14 and other electronic equipment such as the control unit within the device. This design achieves energy self-sufficiency for the monitoring system in the marine environment, significantly reducing dependence on external power supply or frequent battery replacements, thereby ensuring long-term, continuous data acquisition capabilities and improving the operational reliability and environmental adaptability of the entire carbon sink monitoring device.

[0025] See attached document Figure 1-3 As shown, the culture cage 2 is clearly divided into an upper layer 21, a middle layer 22, and a lower layer 23 along its height. In each layer, six measuring positions are evenly arranged around the perimeter of the culture cage. At each position, an external current meter float 31 is installed via a suspension rope 3, and an integrated box 4 is installed at the same height on the side wall of the culture cage. Each integrated box 4 integrates a carbon sink measuring device 41, a feeding device 42, and a fish finder 43. This structure forms at least 18 (3 layers × 6 positions) synchronous monitoring points, enabling real-time, three-dimensional acquisition of wave velocity (current meter), fish distribution (fish finder 43), and the core parameter—water carbon sink content (carbon sink measuring device 41)—at various locations and water depths around the culture cage.

[0026] The control unit continuously executes the following enhanced control cycle: See attached document Figure 2 , 6 As shown, the control unit is located in the waterproof compartment of the float 1 and is electrically connected to equipment such as the meteorological station (14). The control unit receives and integrates data from all monitoring points in real time: based on the data from the flow velocity meters in each direction, it generates two-dimensional and three-dimensional flow field maps of the periphery of the aquaculture cage in real time, accurately identifying the rapid flow zone, the slow flow zone, and the "suitable zone" where the water flow is relatively stable and conducive to the suspension of bait and feeding of fish. It can also integrate the data from all fish finders 43 to construct a real-time three-dimensional density distribution map of the fish population in the aquaculture cage, clearly understanding the aggregation and sparseness of the fish population in the horizontal and vertical directions. In addition, it simultaneously collects the data from each integrated box 4 and the carbon sink measuring device 41 on the central measuring rope 12 to generate a spatial distribution model of carbon sink concentration, identifying carbon sink hot spots and low value areas.

[0027] Its decision-making logic aims to respond to dynamic environmental changes and attempt to optimize aquaculture management. The system does not presuppose complete control over fish behavior, but rather, based on real-time data, its direct goal is to "reduce the loss of feed in rapid currents and guide fish to gather in more suitable feeding areas," thereby potentially creating more favorable biological conditions for carbon sink formation.

[0028] Based on real-time monitoring data, the system may perform or recommend the following control measures: Scenario A (Guided Aggregation): When a slow-flowing area is identified and the fish population in that area is sparse, the system can initiate feeding and release of attractants in that area to attract fish and observe their aggregation effect, allowing the fish to move around in a more stable area.

[0029] Scenario B (Avoidance of Disturbance): Strong currents not only cause food loss, but the turbulence they generate may also resuspend and diffuse fixed carbon (such as particulate organic carbon). The system will decide to guide the fish from these highly turbulent areas to more stable regions, reducing disturbance to deposited carbon and ensuring the fish can continue to produce carbon sinks in a more suitable and stable environment.

[0030] Scenario C (Balanced Promotion): When carbon sink monitoring shows a significantly low carbon sink concentration in a certain water layer (below), it may be due to insufficient biological activity. The system can decide to guide some fish to increase their activity in that water layer by providing stratified feeding, and try to form a higher carbon deposition flux in a suitable area (such as a slow-flowing zone) by utilizing the characteristic of fish excrement as an efficient carbon export carrier.

[0031] Based on the above decisions, the control unit generates specific material feeding control commands: See attached document Figure 2 , 3As shown in Figure 5, the command precisely specifies the particular feeding device 42 to be activated (down to a specific layer and location). The feeding behavior is dynamic and guided. For example, if the first integrated box 4a in the lower layer 23 is a fast-flowing area, and the sixth integrated box 4f in the upper layer 21 is a relatively stable slow-flowing area, in order to guide the fish from the fast-flowing area of ​​the lower layer 23 to the target slow-flowing area of ​​the upper layer 21, the system may control the second integrated box 4b, the fourth integrated box 4d, the fifth integrated box 4e, and the sixth integrated box 4f to release small amounts of highly palatable agents in sequence, forming an induction signal flow, gradually guiding the fish to the target area, and guiding the fish to gather in the target slow-flowing area; after the fish have partially gathered, quantitative and slow-release feed will be started in the target area to consolidate the distribution of the fish and promote feeding and carbon sink cycling. After the feeding guidance is started, the control unit continuously monitors the data of the fish finder 43 to observe the trend of fish distribution changes; at the same time, it pays attention to the data changes of the carbon sink measurement device to assess the actual impact of the control action on the local carbon sink concentration. This feedback is used to optimize subsequent control parameters, forming an adaptive closed-loop management system encompassing perception, decision-making, execution, and evaluation. The system achieves full automation and intelligence in data acquisition, strategy analysis, actuator control, and effect feedback through its control unit. This closed loop not only improves the accuracy of aquaculture management and feed utilization efficiency, but more importantly, the multi-source correlated time-series data generated during its operation provides crucial data support for constructing and validating a coupled model of "hydrological physics, fish behavior, and carbon biogeochemistry," greatly deepening our understanding of the carbon sequestration mechanism in ecological fisheries.

[0032] This embodiment combines a three-dimensional grid layout (upper, middle, and lower layers and multiple horizontal directions) with a core vertical layout to achieve high spatiotemporal resolution synchronous acquisition of carbon sink parameters (such as dissolved inorganic carbon and carbon dioxide partial pressure), hydrodynamics (waves and current velocity), and biological distribution (three-dimensional fish density). This provides an unprecedentedly refined data foundation for analyzing the biogeochemical processes and environmental driving mechanisms of carbon sink formation.

[0033] Example 2: This embodiment details how the control unit in the marine ranch ecological fishery carbon sink data acquisition device realizes the association, storage, and model construction of multi-source data, thereby elevating the device from a data acquisition tool to an analysis platform for carbon sink mechanism research and intelligent management.

[0034] See attached document Figure 1 , 2As shown in Figures 3 and 5, this embodiment is built upon the hardware system of Embodiment 1. The device constitutes a three-dimensional monitoring network through three layers of integrated boxes 4 distributed around the perimeter of the aquaculture cages in six directions, along with carbon sink measurement devices 41, fish finders 43, flow meters, and carbon sink measurement devices 41 on the central vertical measuring rope 12. The carbon sink measurement devices 41 are used to measure the particulate organic carbon (POC) concentration in each area to assess the fishery carbon sink (especially fecal particulate carbon deposition) in that area. This network can continuously and synchronously generate three types of core data streams: point carbon sink concentration data (C), three-dimensional fish population distribution and abundance data (F), and three-dimensional flow velocity and wave data (H). In addition, the start / stop time, location, and feeding amount of all feeding devices 42 triggered by the control unit are recorded as management activity data (M).

[0035] The control unit (with built-in large-capacity memory and data processing chip) acts as the data hub, performing the following core operations: The system adds a high-precision timestamp (UTC time) and spatial coordinate label (e.g., upper layer - azimuth 1, middle layer - center vertical line, etc.) to each data packet. Through a built-in synchronization clock, it ensures that data from different sensors, even with slight transmission delays, are precisely aligned on the time axis. The control unit does not store the received C, F, H, and M data independently, but rather stores them in a structured database indexed by a "spatiotemporal grid." For example, a record in the database might contain: "Time T, Location P, Carbon sink value C at that location." tp Fish density F tp Flow velocity H tp And whether there was a baiting event M at that location before or after time T. tp Data such as wind speed and photosynthetically active radiation collected by meteorological station 14 are also stored as environmental background field data. The above-mentioned associated data continue to accumulate, forming a long-term, multi-dimensional dynamic database of aquaculture environment and carbon sink covering different seasons, tidal cycles, weather events, and management intervention history.

[0036] The data processing capabilities of the control unit extend beyond storage; its advanced function lies in offline or online analysis to establish quantitative relationship models between carbon sink capacity and multiple driving factors. The specific steps are as follows: The system cleans the historical database and extracts key features. For example, it extracts dynamic features such as average velocity, turbulent kinetic energy, and shear stress from velocity data H; behavioral features such as total biomass, aggregation index, and vertical migration amplitude from fish population data F; and calculates vertical gradient, horizontal heterogeneity, and diurnal variation amplitude from carbon sink data C. Using statistical analysis methods or machine learning algorithms, the control unit can fit and establish one or more of the following correlation models to quantitatively analyze the statistical relationship between carbon sink concentration (e.g., particulate organic carbon, POC) in a specific area and the biomass or feeding activity intensity of fish in that area, identifying the direct contribution rate of fish activity to carbon sinks. It establishes the correlation between carbon sink flux or concentration and hydrological parameters such as velocity and turbulence intensity. For example, the model can reveal that slow-flowing areas are more prone to carbon deposition "hotspots," while fast-flowing areas are strongly correlated with carbon resuspension and horizontal transport (potential "leakage"). This study analyzes the response trajectory of fish population distribution (F) after a feeding event (M), and the subsequent changes in local carbon sink (C). This model can be used to assess the impact coefficients of different feeding strategies (such as location and timing) on ​​carbon sink formation efficiency.

[0037] The established correlation model has significant scientific research and management value. The model can quantitatively distinguish how much of the observed carbon sink changes are attributable to fish biological activity and how much is controlled by hydrophysical processes, thus deepening the scientific understanding of the carbon sink formation mechanism in ecological fisheries. The model can also guide intelligent regulation. For example, if the "carbon sink-hydrodynamic drive model" shows that a specific flow velocity range is most favorable for carbon preservation, the control unit can fine-tune its target flow velocity threshold for guiding fish schools, achieving more refined management. Combined with real-time monitoring of fish biomass and hydrological data, the trained model can be used to estimate or predict the carbon sink flux of aquaculture cage systems in real time or in the short term, providing dynamic, process-based methodological support for carbon sink measurement and verification.

[0038] This embodiment integrates isolated sensor readings into a multi-parameter coupled dataset with clear ecological significance through spatiotemporal correlation storage. The device itself becomes a mobile laboratory, and the accumulated data and established models can directly reveal the biogeochemical carbon cycle processes and environmental control mechanisms under fish farming activities on-site. The constructed correlation model provides a quantitative and model-based decision-making tool for optimizing aquaculture management (such as feeding and layout) to maximize carbon sequestration synergy benefits, promoting the transformation of ecological fisheries management from experience-based judgment to a data-driven and model-predictive scientific paradigm.

[0039] Example 3: The embodiment specifically illustrates the bait delivery and replenishment system. This system is a key component of the marine ranch ecological fishery carbon sink data acquisition device, designed to achieve centralized, precise, and efficient bait replenishment to the feeding devices 42 distributed within each integrated tank 4, thereby ensuring the long-term and reliable execution of the intelligent baiting control strategy. (Refer to...) Figure 1-4 As shown, the bait supply system is mainly integrated at the top and inside of the buoy 1, and its core is a distributed material conveying network consisting of pipes, valves and pumps.

[0040] See attached document Figure 3-6 As shown, the feeding port 51 is located at the top of the buoy 1, serving as a centralized interface for external feed input, facilitating batch feeding by operating vessels or automatic feeding equipment. The feeding channel 52 originates below the feeding port 51 and is a multi-branched pipeline system. The first vertical pipe 52a receives feed from the feeding port 51, while the second vertical pipe 52b and the third vertical pipe 52c are parallel conveying vertical pipes, extending to different depth areas of the breeding cage 2. The horizontal pipe 52d horizontally connects the upper parts of the first, second, and third vertical pipes 52b and 52c. A first pump 521 and a second pump 522 are installed on the horizontal pipe 52d for pumping feed between the vertical pipes. Multiple feed pipes 52e are horizontally led out from different height positions of the second and third vertical pipes 52b and 52c, with each feed pipe 52e correspondingly connected to a feeding device 42 of a specific integrated box 4. Each feed pipe 52e is equipped with an electrically controlled shut-off valve 53e at the connection point with the vertical pipe (as shown in the attached diagram). Figure 4 As shown, the system includes a first shut-off valve 531e, a second shut-off valve 532e, a third shut-off valve 533e, a fourth shut-off valve 534e, etc., used to control the opening and closing of the feed channel leading to the corresponding integrated box 4. Each integrated box 4 has a feeding device 42 equipped with a suction pump 42a. The suction pump 42a is connected to the outlet of the corresponding feed pipe 52e.

[0041] The system operates under the coordination of a control unit, enabling on-demand replenishment of designated integrated containers. Its core principle involves controlling the coordinated action of the pump and shut-off valve 53e to guide the bait from the central feeding port to the target integrated container. (See attached diagram.) Figure 4As shown, the following describes the workflow in detail, taking the replenishment of bait to the first integrated box 4a located in the lower area 23 as an example. Operators or automatic feeding equipment feed bait into the feeding port 51. The bait falls into the first vertical pipe 52a by gravity. The control unit generates a replenishment command based on the position information of the first integrated box 4a. First, it closes the first shut-off valve 531e, and simultaneously opens the second shut-off valve 532e and the fourth shut-off valve 534e leading to the first integrated box 4a. The third shut-off valve 533e is normally closed, blocking the bait within the horizontal pipe 52d. The first pump 521 starts, pumping the bait located in the first vertical pipe 52a into the second vertical pipe 52b through the horizontal pipe 52d. Since the second shut-off valve 532e and the fourth shut-off valve 534e are open, the bait falls in the second vertical pipe 52b into the corresponding feed pipe 52e of the first integrated box 4a. When the falling bait passes the valve position, it enters the feed pipe 52e connected to it and accumulates at the end of the feed pipe (i.e., at the interface of the dispensing device 42). Upon receiving a command from the control unit, the suction pump 42a in the first integrated box 4a starts, sucking the bait accumulated at the end of the feed pipe 52e into the bait chamber of the dispensing device 42, completing the replenishment. After replenishment is completed, the second shut-off valve 532e closes, the first pump 521 stops, and the system prepares for the next replenishment task. By programming and controlling different combinations of shut-off valves and the operation of the first pump 521 or the second pump 522 (for example, the first pump 521 is used to feed the integrated box 4 connected to the second vertical pipe 52b; the second pump 522 is used to feed the integrated box 4 connected to the third vertical pipe 52c), the bait can be transported to either the second vertical pipe 52b or the third vertical pipe 52c, regardless of its layer or orientation. Each feed pipe 52e and its shut-off valve 53e are independent, ensuring that the replenishment operations of different integrated boxes do not interfere with each other. Theoretically, this can support sequential or (under the condition that the pipeline flow allows) near-parallel replenishment of multiple boxes. The use of multiple vertical pipes and dual pumps provides path redundancy. For the structural design of the discharge device 42, please refer to the appendix. Figure 6 As shown, a two-layer layout is adopted: the upper layer is dedicated to storing and quantitatively dispensing attractants, while the lower layer is mainly used to contain and transport the main bait. The attractants are consumed at a low rate during actual use and can usually be replenished manually periodically. For high-efficiency centralized replenishment, a parallel feeding pipeline system can be added, referring to the parallel pipeline design method demonstrated in this embodiment, thereby significantly improving replenishment efficiency. The detailed implementation scheme of this parallel pipeline is similar to that of the main bait dispensing pipeline and will not be elaborated further here.

[0042] This embodiment enables remote, targeted, and quantitative replenishment of the distributed intelligent feeding device, seamlessly integrating with the upper-level intelligent feeding control strategy. Centralized feeding at the top feeding port of the buoy allows the control system to distribute feed to all lower-level units, significantly reducing the complexity, manpower requirements, and time costs of offshore operations. The system allows the device to operate long-term with minimal or no human intervention, ensuring that each feeding device is always ready to execute fish-attracting or feeding commands, thereby guaranteeing the continuity and reliability of carbon sink data collection and active management functions.

[0043] Example 4: This embodiment will deploy an experiment to test internal carbon sink growth in a stable marine ranch environment. The observation period is 50 days, and the monitoring points cover the three-dimensional network described in Embodiment 1 (upper, middle, and lower layers, with 6 points in each layer, totaling 18 points, plus the central vertical measurement point). To eliminate the complex influence of natural processes, additional sensors are added to the device integration box 4: a chlorophyll a sensor (for monitoring phytoplankton productivity), a dissolved oxygen sensor (for monitoring microbial degradation), and a salinity sensor (for monitoring water exchange). These sensors communicate with the control unit, and data is collected synchronously. Measurement parameters include particulate organic carbon concentration (POC), fish density, current velocity, chlorophyll a concentration, dissolved oxygen, salinity, and feeding events. Data is collected hourly, and through multi-parameter correlation, carbon sink changes are assessed more scientifically. The entire experimental data is shown in Table 1.

[0044] Table 1. Comparison of Particulate Organic Carbon (POC) Concentration Monitoring Data between Target and Control Sites

[0045] The experimental data clearly demonstrate the technical effectiveness of the device. As shown in the data, in the initial stage of the experiment (day 1), the baseline values ​​of particulate organic carbon (POC) concentration at the target point A (preset slow-flow zone) and the control point B (preset fast-flow zone) were similar, indicating that the initial environmental conditions were consistent and met the requirements of the control experiment. Point C is located in the central area of ​​the middle layer of the breeding cage. Its flow velocity environment is between that of point A (slow-flow zone) and point B (fast-flow zone), belonging to the medium flow velocity zone (e.g., 0.5 m / s). This location was chosen to avoid placing the control point in an extreme flow zone (such as fast flow or near-still water), thereby obtaining a more general and comparable background value.

[0046] By the seventh day, after the system continuously fed and guided fish to point A, the fish population at that point increased significantly, and the POC concentration increased slightly. The POC concentration at points B and C, which were not regulated, only showed slight fluctuations. Meanwhile, the chlorophyll a concentration, dissolved oxygen, and salinity in each area did not change significantly.

[0047] On the fifteenth day of the experiment, the POC concentration at point A increased again to 1.91 mg / m³. 3 The POC concentrations at points B and C were not significantly different from those on the first day. Meanwhile, the chlorophyll a concentration, dissolved oxygen, and salinity in each region did not change strongly. This indicates that the initial increase in POC concentration was mainly due to the fish aggregation effect caused by the feeding guidance strategy of the device, rather than regional environmental changes.

[0048] From day 30 to day 50, with continuous feeding to attract fish, the POC concentration at point A steadily increased to 2.1 mg / m³. 3 The fish population density has remained stable at around 2.8 individuals / m² for a long period. 3 Around 100°C, during this period, the chlorophyll a concentration, dissolved oxygen, and salinity in various areas did not change significantly compared to the first day, indicating that the water area was relatively stable. This eliminates the complex influence of natural processes such as phytoplankton productivity, water exchange, and microbial degradation on carbon sinks. This proves that under the conditions of this experiment, the fish aggregation effect induced by feeding was the dominant factor in increasing POC concentration.

[0049] In summary, the experimental data demonstrates that the device of the present invention can effectively attract fish to gather through its feeding device 42, and achieve and maintain an increase in the concentration of particulate organic carbon in the target area by regulating the feeding strategy, thus demonstrating certain technical effects in carbon sink regulation.
