Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, and in particular to an intelligent ecological fish farming system. Background Art

[0002] According to the Food and Agriculture Organization of the United Nations (FAO), the world's aquaculture output increased from 3.9% of the total fishery output in 1970 to 41.3% in 2011, indicating that the increase in aquatic products mainly comes from aquaculture. The contribution of aquaculture to the fishery economy mainly comes from developing countries. Aquaculture is an environment-dependent industry, and the quality of the water environment determines the success or failure of aquaculture and the quality and safety of products. However, aquaculture also produces its own pollution, posing a threat to the surrounding water environment and ecosystem, thereby restricting its sustainable development. From the perspective of the entire aquaculture industry chain, the quality of the ecological environment is the key.

[0003] China is a major fishing country in the world. In 2012, the total output of aquatic products reached 59.0768 million tons, accounting for about 38% of the total global aquatic products, ranking first in the world for 24 consecutive years. In 2012, the total area of ​​aquaculture in China was 8.0884 million hm2. 2 , the total aquaculture output reached 42.8836 million tons, accounting for 72.59% of China's total aquatic product output and 70% of the world's total aquaculture output. China has become the only country in the world where aquaculture output exceeds fishing output, and aquaculture output continues to grow rapidly. However, the pressure on the ecological environment of the waters brought about by the rapid development of China's society and economy is significantly affecting the sustainable development of the aquaculture industry. In view of the important position of aquaculture in China and the special relationship between aquaculture and the environment, the control and management of aquaculture environmental pollution is increasingly attracting widespread attention from all sectors of society.

[0004] Ecological fish farming is an inevitable trend of social development and the key to pollution-free aquaculture. To optimize the farming model under the guidance of "ecological priority", it is necessary to adjust the farming structure and achieve industrial upgrading. Ecological fish farming includes many main models, such as factory-scale recirculating aquaculture, land-based circular pond recirculating aquaculture, indoor fish and vegetable symbiotic farming, offshore new cage farming, and deep-sea facility farming. These models can improve farming efficiency and output while minimizing the burden on the ecological environment.

[0005] Factory-scale recirculating aquaculture and land-based circular pond recirculating aquaculture can realize the recycling of water resources, strictly control water quality and environmental parameters, and are suitable for high-density aquaculture. However, its disadvantages are high initial investment costs, large land area, and professional technical maintenance. Indoor fish-vegetable symbiotic aquaculture can save land, achieve water purification and recycling, but its scale is limited and the investment return cycle is long. New offshore cage aquaculture and deep-sea facility aquaculture have expanded the aquaculture space and reduced local water pollution. However, in recent years, with the gradual improvement of environmental protection requirements, in order to avoid the pollution of aquaculture water bodies and the destruction of the ecological balance of the water environment, traditional cage aquaculture that relies on reservoirs, lakes, and rivers has been gradually banned. These ecological fish farming models fully reflect the concept of "ecological priority". By optimizing the aquaculture structure and improving technical means, the aquaculture efficiency and product quality have been improved, the ecological environment has been protected to the maximum extent, and the sustainable development of aquaculture has been achieved. However, each model has certain disadvantages, especially the large land area and the use of a large amount of agents to inhibit pests and diseases. Targeted measures need to be taken to further optimize and improve them to ensure the long-term promotion and application of ecological fish farming technology.

[0006] A large amount of tailwater is also generated during aquaculture. If it is not properly handled, it will cause serious pollution to the surrounding water environment. The main manifestations are eutrophication caused by excessive nutrients, organic pollution that reduces dissolved oxygen, and ecological risks caused by drug and pathogen residues. To solve these problems, we should focus on the standardized ecological transformation of ponds and the management of aquaculture tailwater, and support the upgrading and transformation of tailwater treatment facilities such as ecological ditches, ecological ponds, and subsurface wetlands. Optimize and improve technical models such as artificial wetland ecological treatment of contiguous pond aquaculture tailwater and "three ponds and two embankments" ecological treatment of pond aquaculture tailwater. Study tailwater purification technologies such as physical, chemical, and biological methods, focus on demonstrating and promoting technical models such as "mechanical filtration, ecological pond degradation, and microbial purification" for aquaculture tailwater treatment, and select a batch of new facilities and equipment with good aquaculture tailwater treatment effects and low costs.

[0007] The large-scale use of various drugs and chemical additives in aquaculture will also cause certain harm to the water environment and human health. The main manifestations are that drugs and their metabolites may remain in aquaculture water and products, posing a potential threat to human health; these chemicals can also cause serious ecological pollution and damage aquatic ecosystems through tailwater discharge; long-term improper use may also lead to drug resistance in pathogens, increasing the difficulty of future prevention and control; if the drugs and chemicals remaining in aquaculture products enter the food chain, they will endanger the health of consumers. To solve these problems, we should vigorously promote green ecological disease prevention technology, strengthen disease monitoring and early warning, effectively improve the ability to respond to emergencies, and achieve early detection, early reporting, and early disposal. We should fully implement the quarantine system for the origin of aquatic seedlings and steadily start the construction of seedling farms without prescribed aquatic animal diseases. We should make good use of the "Fish Disease Telediagnosis Network" and provide good technical guidance services. We should carry out rural activities to monitor the drug resistance of major pathogens in aquatic animals and standardize the use of drugs, and guide breeders to use fishery veterinary drugs in a scientific and standardized manner.

[0008] The aquaculture industry has long used young fish as feed, a practice that poses many serious hazards. Large-scale fishing of young fish will lead to the rapid depletion of marine fishery resources, seriously disrupt the marine ecological balance, and threaten the survival of many rare and endangered fish. The nutritional composition of young fish does not fully match the needs of farmed fish, making it difficult to meet the latter's comprehensive nutritional needs, affecting the breeding effect. In addition, large-scale fishing of young fish will also cause an imbalance in the marine food chain, and other marine organisms that rely on young fish for food will also be seriously threatened, leading to a chain of ecological disasters. At the same time, the large amount of waste and tail water generated in the production process of feed made from processed young fish will also cause serious environmental pollution.

[0009] Therefore, a series of technical measures should be taken to improve and strengthen the ecological fish farming model, enhance the disease resistance of fish, reduce production costs, and improve breeding efficiency, so as to produce safe aquatic products that meet the requirements of people and the ecological environment.

A drainage pipe is provided at the bottom of the farming pond 11, and the drainage pipe is connected to the water collection tank 12. The input end of the water purification, filtration and sterilization device 13 is connected to the water collection tank 12 (through a water pump), and the output end of the water purification, filtration and sterilization device 13 is connected to the farming pond 11 through a clean water pipe. The output end of the oxygen-enriched water production device is connected to the water collection tank 12. The oxygen-enriched water production device can be arranged in the water collection tank 12 or independently. In order to maintain good water quality, the system is equipped with an advanced water treatment system. On the one hand, an oxygen-enriched water production device with high-efficiency dissolved oxygen is integrated. The oxygen-enriched water production device can produce dissolved oxygen. Oxygen-enriched water with high oxygen concentration is transported from the output end of the oxygen-enriched water production device to the water collection tank 12.

The input end of the fish suction pump 41 is connected to the water collecting pool 12 through a pipeline, and the output end of the fish suction pump 41 is connected to the fish discharge pipe 42. The finished fish is first transported from the breeding pond 11 to the water collecting pool 12, and then the fish suction pump 41 sucks the finished fish from the water collecting pool 12 to the fish discharge pipe 42, and the fish is transported to the destination through the fish discharge pipe 42. The fish discharge pipe 42 is made of high-strength, corrosion-resistant stainless steel. The inner wall of the pipe is smooth, which can minimize the damage of the fish during transportation. The pipeline adopts a modular design, and the pipeline length and the number of branches can be flexibly configured according to the breeding scale and output requirements.

[0037] The controller 5 is electrically connected to the breeding equipment 1, the feeding equipment 2, the water quality monitoring equipment 3 and the fish-discharging equipment 4 respectively. The data detected by the water quality monitoring equipment 3 will be transmitted to the controller 5, and the controller 5 can control the breeding equipment 1, the feeding equipment 2 and the fish-discharging equipment 4. Among them, the controller 5 can control the oxygen-enriched water production device (including controlling the start and stop and output power of the oxygen-enriched water production device) according to the data detected by the dissolved oxygen sensor and the ammonia nitrogen sensor, so that the dissolved oxygen concentration of the water in the breeding pond 11 is controlled within the range of 6-8 mg / L.

[0038] The controller can receive data from various devices in real time, including data from water quality monitoring, automatic feeding, fish output and other links. The controller will conduct in-depth analysis and modeling of these massive data, explore the inherent laws and trends, and provide comprehensive data support for aquaculture management. Based on the results of data analysis, the controller can automatically formulate a scientific and reasonable aquaculture plan. For example, it can predict future water quality changes based on water quality monitoring data and intelligently adjust the operating parameters of the oxygen-enriched water production device; accurately predict the daily feed input required based on historical feed consumption; analyze market demand changes based on fish output data, optimize production plans and fish output strategies, etc. These automated decisions and executions have greatly improved aquaculture efficiency and product quality. At the same time, the controller also provides a visual data display and operation interface for farm managers. Managers can monitor various production indicators in real time and conduct manual intervention and adjustments. The controller can also continuously optimize the user interaction interface and decision support functions based on the operating habits of managers. In addition, the controller also has the ability of remote monitoring and mobile management. Through cloud servers and mobile applications, managers can grasp the production and operation status of the farm anytime and anywhere, and conduct remote management and control.

[0039] In this system, the water quality in the breeding pond can be monitored in real time through the water quality monitoring equipment, and the relevant data can be fed back to the controller; the water in the breeding pond is transported to the water collection tank through the drainage pipe, and the water pump pumps the water in the water collection tank to the water purification, filtration and sterilization device, and the water is filtered, purified and sterilized. The water is transported back to the breeding pond through the clean water pipe to form a closed-loop water circulation system, thereby continuously purifying and sterilizing the water in the breeding pond. The controller can regulate the power of the water pump, so that the water circulation rate can be automatically adjusted according to the breeding density; the controller can control the start and stop and output power of the oxygen-enriched water production device according to the data detected by the dissolved oxygen sensor, so that the dissolved oxygen concentration of the water in the breeding pond is controlled within the range of 6-8mg / L to meet the physiological needs of high-density breeding fish; the present invention adopts integrated breeding equipment, feeding equipment and fish-discharging equipment, etc., which can control the entire breeding environment Systematic management is carried out instead of being limited to a single fish pond, which improves the overall efficiency of aquaculture. The water quality in the aquaculture pond can be monitored in real time through water quality monitoring equipment, as well as fish growth status, water quality and other parameters. The controller can automatically adjust feed delivery and dissolved oxygen concentration, greatly improving the accuracy and efficiency of feeding management. Equipped with water quality monitoring equipment and water purification, filtration and sterilization equipment, it can quickly detect and deal with water quality problems, maintain good water quality in the aquaculture environment, and thus ensure aquaculture results. The controller is electrically connected to the aquaculture equipment, feeding equipment, water quality monitoring equipment and fish output equipment, respectively, to achieve global optimization and regulation, greatly improving the intelligence level and controllability of aquaculture. Through systematic and intelligent aquaculture management, it can significantly improve aquaculture efficiency and product quality, while reducing environmental load and enhancing the sustainable development capacity of aquaculture.

[0040] Exemplarily, vegetables are planted on the liquid surface of the water collection pool by the bare root method or the substrate cultivation method. The bare root method is to cover the cultivation tray with a hard foam board, open holes every 15 cm, and implant the roots of the seedlings wrapped in sponge into the holes, with the roots exposed in the immersion tray; the substrate cultivation method is to plant the seedlings in a substrate pot (with vermiculite inside), and the water overflows into the cultivation tray after filtration, is absorbed by the roots and filtered by the substrate, and the purified water flows back to the breeding pond; for freshwater aquaculture, vegetables are planted in the breeding pond to form a fish-vegetable symbiotic system. These plants can utilize nutrients in the water, such as ammonia nitrogen and phosphorus, to carry out photosynthesis, thereby effectively reducing the eutrophication of the water. At the same time, the roots of plants can provide a good hiding place for fish and reduce their stress response. For marine aquaculture, the technology of ammonia nitrogen stripping tower can be used. In marine aquaculture, the concentration of ammonia nitrogen in the water is often high and requires special treatment methods. The stripping tower uses aeration and pH adjustment to convert the ammonia nitrogen in the water into gaseous ammonia, thereby achieving the purpose of removing ammonia.

[0041] Exemplarily, the side walls of the breeding pond are covered with a corrosion-resistant smooth layer, such as corrosion-resistant fiberglass or high-density polyethylene, which makes the side walls smooth, can effectively prevent bacterial attachment and water pollution, and is easy to clean and maintain.

[0042] For example, the bottom of the breeding pond is a gradually shrinking cone, which is conducive to the automatic collection and discharge of fish feces. The diameter of the breeding pond is 10m, 20m and 30m, and the diameter of 20m is recommended. The water volume of a single breeding pond is 670m 3 The recommended stocking density is 100 fish / m 3 .

[0043] For example, multiple breeding ponds are arranged vertically, that is, vertically stacked. Multiple breeding ponds are respectively arranged on supporting buildings, that is, layered breeding technology is adopted to effectively reduce the floor space. It is understandable that the strength of the supporting building is sufficient to support multiple breeding ponds. After comparing 4-layer, 6-layer and 8-layer, the 6-layer scheme is recommended. The water volume of a single 6-layer breeding pond is 4020m 3 .

[0044] Exemplarily, the breeding equipment also includes a heating device capable of heating the water in the breeding pond and a cooling device capable of cooling the water in the breeding pond. The heating device and the cooling device are respectively electrically connected to the controller. When the water temperature deviates from the optimal range, the system can automatically start heating or cooling to adjust the water temperature to an appropriate level.

[0045] Exemplarily, the fish delivery equipment also includes a visual recognition weighing device arranged at the outlet end of the fish delivery pipe, which can take a picture of the fish body sent out from the fish delivery pipe, and obtain the type of the fish body by identifying the image of the fish body taken, and obtain the weight of the fish body by calculation. The fish delivery equipment also includes a sorting device, which can classify and store the fish body sent out from the fish delivery pipe according to the type and weight of the fish body obtained by the visual recognition weighing device, and can monitor and record the weight data of each batch of fish in real time, and automatically classify and collect finished fish of different specifications according to the preset threshold value; a temporary storage area is provided at the outlet of the fish delivery pipe, and a water tank design is adopted to keep the water clean and the water temperature suitable, so as to ensure that the fish maintain a good vitality during the short stay. The operation status of the entire fish delivery equipment will be transmitted to the controller in real time, and the management personnel can timely discover and solve problems through the monitoring interface, ensure the stability and efficiency of the fish delivery process, greatly shorten the fish delivery time, reduce the mortality rate of finished fish, and provide strong guarantee for the subsequent processing and sales of aquatic products.

[0046] Exemplarily, a metering valve is provided at one end of the feed delivery pipe connected to the breeding pond, which can accurately adjust the amount of feed delivered for each feeding.
