Mindanao State University Develops SmartRAS to Enhance Mangrove Crab Hatchery Success
Mindanao State University's Iligan Institute of Technology is developing the SmartRAS, a recirculating aquaculture system aimed at improving hatchery survival rates for mangrove crabs and reducing dependence on wild-caught populations. This innovative system enhances water quality and temperature control, resulting in higher survival and spawning rates while minimizing ammonia and nitrite levels. Research indicates that maintaining an optimal temperature of 27 degrees Celsius significantly boosts broodstock survival and reproductive performance.

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.
