The RAS (Recirculating Aquaculture System) for industrial indoor mud crab farming is a modern farming solution based on high-density, controlled environment technology. This system utilizes recirculating water treatment combined with biological, mechanical, and electronic components to simulate natural growth conditions while achieving water purification, temperature regulation, and disease prevention.

• Farming Unit: Three-dimensional "crab apartment" design with food-grade polypropylene (PP) boxes that simulate natural cave environments
• Water Treatment System: Includes high-speed sand filter, protein skimmer, and biological filter for comprehensive water purification
• Disinfection Equipment: UV sterilizers or ozone equipment for pathogen control
• Monitoring System: Real-time sensors for pH, dissolved oxygen, salinity and other critical parameters
• Recirculating Facilities: Water pumps, storage tanks, and sewage disposal for efficient water recycling

• High Efficiency: Enables continuous year-round production with significantly increased output
• Environmental Control: Reduces disease transmission risk and increases survival rates by 4x
• Resource Conservation: Minimal power consumption (≈100 kWh/month) and small footprint (1/10 of traditional farming)
• Quality Assurance: Produces uniform, high-quality crabs free from antibiotic residues
• Sustainability: Reduces wastewater discharge and environmental impact
