Technology empowers agriculture, enabling humans to eat better

Recently, the official website of the Ministry of Agriculture and Rural Affairs released 14 typical cases of smart agriculture under the special topic "Smart Agriculture in Action" (Local Practice), providing reference and inspiration for the development of smart agriculture. Among them, the intelligent aquaculture model of Guangming Fisheries Co., Ltd.'s aquatic product engineering pond, supported by Jiangsu Three&three, was successfully selected. This honor is not only a high praise and recognition of Guangming Fisheries' outstanding achievements in the field of intelligent fisheries, but also a powerful witness to Jiangsu Three&three's professional accumulation and technical strength in the field of intelligent fisheries!

1、 Basic information

Guangming Fishery Co., Ltd. is a subsidiary of Guangming Food Group Shanghai Farm Co., Ltd. It is the largest standardized aquaculture farm in Shanghai and a key leading enterprise in agricultural industrialization. It specializes in the breeding, cultivation, processing, and sales of freshwater fish. Guangming Fishery has an 80000 acre aquaculture base with an annual output of 50000 tons of freshwater fish and 2600 tons of processed frozen aquatic products. The products are sold on major fresh e-commerce platforms and traditional supermarkets, achieving full traceability from the pond mouth to the dining table.

Application status of information technology equipment

（1） Practical production issues

There are problems with difficult employment and high labor intensity in aquaculture production. Currently, the general age of the operating workers is around 60 years old, making it difficult to recruit young labor to participate in production; During the peak period of aquaculture, there are more heavy physical labor and higher labor intensity. Production experience cannot be solidified, problem handling experience cannot be summarized, and the experience accumulation and guidance of breeding personnel rely almost on word of mouth. A large amount of production management and problem handling experience has not been systematically summarized. Climate, diseases, and other factors have a huge impact on aquaculture production. Employees need to be on duty 24 hours a day in high temperature or adverse weather conditions, and they need to carry out normal production operations in adverse weather conditions, which poses a high safety risk.

（2） Practice mode

One is the digitization of aquaculture management. Build a comprehensive production management system, establish a data collection system covering the entire process of breeding, breeding, processing, and sales, integrate modules such as cost, warning, quality, performance, and analysis, establish a basic database for fishery breeding, and solidify and standardize production processes. Establish safety valves and critical warning values for relevant parameters, form a breeding warning expert system, and provide guarantees for scientific management, disease prevention, quality and safety. Establish a product quality traceability system, achieve "QR code" certification sales, and form a safety information traceability chain with traceable sources and accountability. Build a sales management platform for the entire product area, automatically settle and calculate the weight of each box, integrate base sales IoT devices, link door defense systems, establish control processes, achieve sales automation and visualization, strengthen sales internal control and security.

The second is the automation of the breeding process. Automatic control transformation of various links in fishery aquaculture production. Establish a pump room control system to achieve automation of pump room pipe water. Utilizing intelligent feeding towers for automatic remote feeding throughout the entire process, daily feeding times, feeding duration, and feeding amount are set based on breeding species, specifications, pond storage capacity, and other data to achieve automatic feeding of the system. Online integrated aquaculture water quality monitoring system, automatically collecting dissolved oxygen pH、 Water temperature and other data, real-time monitoring of water quality changes 24 hours a day, linked with an aerator to achieve automatic operation. The integrated aquaculture production video monitoring management system systematically associates feeding equipment, oxygenation equipment, monitoring equipment, and environmental monitoring equipment in the production area with the pond as the basic management unit. One pond, one interface, remotely controls the production management facilities and equipment at each pond mouth, improving the safety of fish pond production management.

The third is the precision of production operations. In the process of releasing seedlings, detailed records of key information such as the variety, tail number, and weight of the seedlings are kept. The tail number of the released seedlings is used as a key value throughout the entire breeding process, and the pond mouth data model is corrected in a timely manner based on the dead end tail number to accurately estimate the survival rate, dead end rate, and other data of the pond mouth. Accurately adjust production strategies, with a sampling cycle of 15 days, and regularly update breeding management data through sampling. The system automatically calculates the total amount of fish stored in the pond based on sampling parameters, and estimates the total amount of water products that can be sold in the pond. By combining water quality information, meteorological information, and real-time monitoring feedback video information, production measures are adjusted to achieve precise oxygenation and feeding, effectively avoiding the abuse and misuse of inputs, reducing ecological damage while saving costs, and continuously improving the ecological environment of aquaculture waters.

（3） Technological innovation

One is the linkage between video surveillance and equipment. Flexibly utilize the video surveillance equipment originally only used for observing fish feeding, set up prefabricated points, and link the operation status of the aerator in the background. When one or several aerators are remotely controlled to be turned on, the fixed position observation spherical camera will trigger a rotation of the aerator points. In addition, it can also inspect key intersections, key equipment, and other locations in the site to prevent theft.

The second is precise data control. All equipment operation data within the breeding area are stored in the central database. The wireless oxygenation control system accurately records the operating time of the aerator, calculates the distribution of main electricity usage and the cost of electricity resource usage in the area; The intelligent feeding system can monitor the operation data of the transmission tower in real time through the online weighing sensor at the bottom of the tower.

The third is intelligent pump station management. The remote control transformation of the water pump station in the aquaculture area is carried out, and the working status of the pump station is monitored in a timely manner through devices such as video, temperature, current, and voltage. Management personnel can remotely turn on the water pump according to the monitoring situation, which improves work efficiency and the ability to resist risks of frequent water changes in high-density aquaculture. The fourth is one key protection for all regional devices. In adverse weather conditions, all IoT devices in the breeding area can be powered off and remotely restored with one click through the central control room to avoid thunderstorm hazards.

3、 Cost effectiveness

The landing application of intelligent aquaculture system helps Guangming Fishery to achieve a stable transformation of aquaculture mode and plays a decisive role in reducing aquaculture costs. According to estimates, from 2021 to 2022, 1 The amount of bait used in the 20000 acre aquaculture management area decreased from 11302 tons to 8755 tons, a year-on-year decrease of 17%; The cost of feed decreased from 48.39 million yuan to 33.22 million yuan, a year-on-year decrease of 31%; The total cost of related labor (technical personnel+management personnel) decreased from 4.3 million yuan to 3.52 million yuan, a year-on-year decrease of 18%; The cost of electricity resource consumption has decreased from 1.74 million yuan to 1.29 million yuan, a year-on-year decrease of 25%. The overall hardware investment for the informationization transformation of the aquaculture management area is about 17 million yuan, software investment is about 2.44 million yuan, and the annual maintenance cost of hardware equipment is about 800000 yuan.
