What is RAS-IMTA?

RAS-IMTA combines two cutting-edge aquaculture technologies to create a highly efficient, environmentally sustainable shrimp farming system that is particularly well-suited for integration with solar energy.

RAS: Recirculating Aquaculture System

A closed-loop water management system that filters, treats, and recirculates water through the farm. Unlike traditional ponds that exchange water with the environment, RAS continuously cleans and reuses water, dramatically reducing water consumption and environmental impact.

Key Benefits:

  • 90% reduction in water usage
  • Controlled water quality parameters (temperature, salinity, oxygen)
  • Higher stocking densities (super-intensive farming)
  • Minimal discharge of waste water
  • Year-round production regardless of weather

IMTA: Integrated Multi-Trophic Aquaculture

A polyculture approach where multiple species from different trophic levels are farmed together. Waste from shrimp (nutrients) becomes food for secondary species (e.g., seaweed, mollusks), creating a balanced ecosystem.

Key Benefits:

  • Natural waste treatment (biological filtration)
  • Additional revenue streams (seaweed, clams, tilapia)
  • Improved water quality through nutrient uptake
  • Circular economy model
  • Enhanced environmental sustainability
Perfect Match

Why Solar4Shrimp is Ideal for RAS-IMTA

Energy-Intensive Operations

RAS systems require continuous power for aeration, water pumping, filtration, and temperature control. Electricity can represent 40-60% of operating costs. Solar drastically reduces this burden.

☀️

Daytime Load Matching

Peak solar generation (10am-3pm) coincides with maximum water treatment and pumping needs during feeding and water exchange cycles.

💰

ROI Acceleration

Higher energy consumption means greater absolute savings. A RAS farm spending 100M VND/month on electricity can save 30M+ VND/month with Solar4Shrimp.

🌱

Environmental Alignment

Both RAS-IMTA and solar are premium "green" technologies. Farms using this combination can qualify for carbon credits, eco-certifications, and premium market pricing.

RAS System Integration Points

🌀 Aeration Blowers

Largest load: 60-70% of total farm electricity. Operate 24/7. Solar powers during day, grid at night.

💧 Water Pumps

Recirculation pumps (15-20% of load). Optimized to run during peak solar hours.

🧪 Biofilters & UV Sterilization

Continuous operation, ~10% of load. Solar reduces daytime grid draw.

🌡️ Temperature Control (Seasonal)

Heating/cooling as needed. Solar offsets HVAC load during hot days.
