I. Building a 24/7 All-Weather Surveillance Network
1. Comprehensive Coverage Capability
China has established the world's largest coastal radar network (covering 92% of its 12,000 km coastline), integrated with satellite radars to form a "space-air-coast-sea" four-dimensional monitoring system. This enables 24-hour dynamic surveillance of the 200-nautical-mile exclusive economic zone. In 2024, illegal fishing cases in the East China Sea dropped by 48%, thanks to the radar system processing 230 million vessel trajectory data points daily.
2. Dark Vessel Identification Revolution
The fusion of radar, AIS, and optical technologies exposes vessels with disabled tracking devices. In the Zhoushan Archipelago pilot project, the system identified 17,000 "ghost ships" and intercepted illegal catches equivalent to three West Lake volumes of fish resources.
II. Redefining Maritime Law Enforcement Efficiency
3. Smart Law Enforcement Trigger
Electronic fencing in the Yangtze River decade-long fishing ban zone triggered 56,000 annual alerts, coordinating drones and unmanned boats for precise interceptions. In 2024, interception success rates surged 3.2-fold compared to traditional methods. The Bohai Bay phased-array radar reduced violation response times to 8 seconds, achieving a "violation-instant exposure" deterrent effect.
4. Non-Contact Evidence Chain
Radar trajectory data was recognized as judicial evidence by China’s Supreme Court. In 2024, 87% of national fisheries litigation cases used radar trajectory maps as core evidence, shortening trial cycles by 22 days on average.
III. Enabling Sustainable Fisheries Resource Management
5. Precision Fishing Intensity Measurement
Radar scanning frequency and trajectory density analysis in Zhoushan, Zhejiang, reduced single-vessel catch measurement errors to ±12%. Dynamic quota adjustments boosted hairtail resources by 39% over three years. This model will expand to 11 major fishing grounds nationwide by 2025.
6. Scientific Resource Regeneration Assessment
Radar-monitored large yellow croaker spawning grounds expanded to a historic 12,000 km². Combined with sonar data, optimized restocking strategies accelerated wild population recovery by 2.8 times.
IV. Safeguarding Marine Ecological Security
7. Environmental Pollution Sentinel
Radar oil-film detection systems in the Bohai Sea identified 0.01 mm-thick pollutants, tracing 56 illegal discharge cases in 2024 and reducing ecological losses by ¥18 billion. Qingdao’s coastal radar network provided 48-hour red tide warnings, saving aquaculture farmers ¥930 million.
8. Ecological Restoration Benchmark
Radar 3D modeling of artificial reefs in the Pearl River Estuary achieved <2 cm settlement error, enabling precise restoration assessments. By 2025, this technology will guide 38 marine ranch projects nationwide, boosting biomass capacity by 41%.
V. Constructing an Intelligent Emergency Management System
9. Disaster Early Warning Vanguard
Real-time radar tracking of 120,000 fishing vessels during typhoons ensured zero casualties in the 2024 "Plum Blossom" typhoon, guiding 32,000 vessels to safety. Radar current inversion improved storm surge prediction accuracy to 95%, saving coastal cities ¥2.7 billion annually in disaster costs.
10. Search-and-Rescue Coordination Hub
The BeiDou-radar fusion system narrowed search areas for missing targets to a 500-meter radius. In 2024, 137 fishermen were rescued in the South China Sea, with average rescue times cut to 4.7 hours.
VI. Establishing Global Governance Leadership
11. Standardization Authority
China-led ISO 21780 *Fisheries Radar Data Specifications* was adopted by 43 nations. Qingdao’s radar equipment exports reached 17 Belt and Road countries. The 2025 Global Fisheries Monitoring Summit in Xiamen will showcase China’s expertise.
12. Blue Economy Catalyst
Smart fisheries governance boosted China’s distant-water fishing compliance rate to 98%. The EU lifted trade restrictions on 32 Chinese seafood firms, with 2025 exports projected to rise by ¥24 billion.
Conclusion: From Technological Revolution to Governance Revolution
When radar data flows synchronize with oceanic rhythms, and electromagnetic beams weave a protective grid for ecosystems, smart fisheries governance transcends mere technology—it becomes the core engine of modern marine governance. This transformation not only reshapes the spatiotemporal dimensions of fisheries regulation but also, at the intersection of data and ecology, writes a new chapter of human-ocean symbiosis. Here, every radar echo pulses with sustainable development, and every trajectory trace defines a new philosophy of governance for our blue planet.
