Mindanao State University’s Iligan Institute of Technology is developing a recirculating aquaculture system to improve hatchery survival rates for mangrove crabs, which is ultimately expected to reduce the reliance on wild-caught crabs for breeding. The Philippines is a major producer of mangrove crabs (Scylla serrata), supplying both domestic and export markets. However, most hatcheries still rely on wild-caught broodstock, which has raised sustainability concerns. The system, called SmartRAS provides controlled rearing conditions for immature adult crabs, particularly through temperature regulation and improved water quality management.
