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.
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.
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.
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.
Peak solar generation (10am-3pm) coincides with maximum water treatment and pumping needs during feeding and water exchange cycles.
Higher energy consumption means greater absolute savings. A RAS farm spending 100M VND/month on electricity can save 30M+ VND/month with Solar4Shrimp.
Both RAS-IMTA and solar are premium "green" technologies. Farms using this combination can qualify for carbon credits, eco-certifications, and premium market pricing.
