MINDANAO State University's Iligan Institute of Technology is developing the SmartRAS, a recirculating aquaculture system to enhance hatchery survival rates for mangrove crabs, reducing reliance on wild-caught crabs. The system improves water quality and temperature control, addressing survival and spawning rates below 40% in conventional systems.

Research indicates SmartRAS results in higher survival, spawning, and hatching rates, maintaining lower ammonia and nitrite levels. The optimal temperature for broodstock survival and reproductive performance is identified at 27 degrees Celsius. The design reduces cannibalism, leading to healthier larvae and improved seed production consistency.
