It is now feasible to raise ulang (giant freshwater prawn) in fish cages in lakes. The technology was developed and continues to be refined under a collaborative project on the development of a genetically improved strain of this shrimp species scientifically named Microbrachium rosenbergii. The project is being implemented in the Philippines, Indonesia, and Thailand. From 2003-2005, it was part of an ASEAN-SEAFDEC (Association of Southeast Asian Nations-Southeast Asian Fisheries Development Center) Special Five-Year Program on Sustainable Fisheries for Food Security in the Region.
