Sensing: Sensors (pH, DO, water level, ultrasonic flow)
Transmission: Data loggers (default 5-minute sampling), gateways
Control: Water exchange, aeration, feeding systems
Video: Underwater robots for inspection/thermal cameras (fish behavior analysis)
High-definition cameras deployed at critical points (e.g., drainage outlets, feeding stations)
Parameter | Sensor Type | Optimal Range | Risks Beyond Range |
---|---|---|---|
Dissolved Oxygen (DO) | Optical/Electrode Sensor | ≥5mg/L (breeding) | <3mg/L: Mass mortality |
Ammonia Nitrogen | Ion-Selective Electrode | ≤0.2mg/L (hatchery) | >2mg/L: Acute toxicity |
Temperature | Waterproof Probe | Species-specific* | ±5°C disrupts metabolism |
pH | Glass Electrode | 6.5–8.5 (freshwater) | <6.5 or >9.0: Gill damage |
Turbidity | Optical Scattering | <50 NTU (clear water) | High turbidity reduces respiration efficiency |
Leveraging digital twin technology, the system integrates sensor data and video surveillance to build an interactive 3D aquaculture environment model. This enables:
Data visualization and remote management via mobile APP/PC terminals.
Tiered alerts (critical/over-threshold) for real-time monitoring.
Automated pond control (water exchange, aeration, feeding triggered by thresholds), significantly reducing labor and resource use while achieving precision farming.
1. Efficiency Improvement & Cost Reduction
Reduces labor dependency through automated equipment (smart feeding, aeration) and data-driven management, minimizing feed and energy waste.
2. Risk Mitigation
Real-time water quality monitoring (DO, ammonia nitrogen) and fish health analysis for disease prediction and early warnings, preventing large-scale losses.
3. Green & Sustainable Practices
Reduces pollution via recirculating aquaculture systems and biocontrol methods, aligning with environmental policies for eco-friendly production.
4. Quality Assurance & Traceability
Full-process data logging using blockchain technology to meet consumer demands for food safety and transparency.
5. Standardization & Scalability
Unified technical standards enable modular system expansion, supporting intelligent upgrades for aquaculture farms of all scales.
Hatchery Management: Strict control of NH₃-N ≤0.2mg/L and DO ≥5mg/L.
Feeding Optimization: Adjust feed based on ORP to reduce waste.
Disease Prevention: Detect pH fluctuations (±0.5/hour) signaling potential outbreaks.
