This collaborative SEAFDEC/ASEAN project aimed to develop sustainable shrimp culture technology packages to address the problems in shrimp culture (e.g. discharges from shrimp farms threatening mangrove and marine ecosystems, clearing of mangrove forests to make way for shrimp ponds, etc.). In this context, a closed recirculating shrimp farming system is discussed touching on: pond preparation, water preparation, stocking, feeding, management, DO level, problems, record keeping, and harvesting.
