Second round table discussion on the development of genetically improved strain of Macrobrachium: A collaborative research under the Aquaculture Component of the ASEAN-SEAFDEC Special Five-Year Program on Sustainable Fisheries for Food Security in the ASEAN Region
The Second Round Table Discussion on the Development of Genetically Improved Strain of Macrobrachium was held in the Philippines in September 2004 to evaluate the progress of activities of the collaborative research and as a follow-up to the First Round Table Discussion, which was convened in Indonesia in 2003. During the said Round Table Discussion, the delineation of responsibilities was agreed upon by the participating countries – Indonesia, the Philippines, and Thailand. One of the recommendations during the First Round Table Discussion was to conduct a yearly evaluation of the project activities to enable the experts to get to know of each other’s activities and come up with a consistent and improved technology on production of good quality freshwater prawn seeds that can be made available for rural aquaculture in the region.
This publication contains the progress of the collaborative research presented during the Second Round Table Discussion.

Freshwater prawn program of BFAR
Tayamen, Melchor M.
The giant freshwater prawn (Macrobrachium rosenbengii) is one of the indigenous prawns found in many parts of the country. Locally known as ulang, it is a hardy species that is easily farmed. On the average, farmed ulang weighs from 30 to 100 grams, which translates to 10 to 25 pieces per kilo. This is very much comparable to the medium to large or jumbo sizes of brackishwater tiger shrimps or sugpo. In the wild, ulang grow as much as 500 g and sells at 300 to 350 pesos/kg ($1=P55.50), however, the quantity harvested is limited and is dependent on its seasonality.
Despite the development of both hatchery and grow-out technologies for ulang, there is really no significant commercial production in the country yet, except in BFAR-operated hatcheries in Muñoz and in Dagupan. To date, the only private ulang hatchery is MBL Farms producing up to 150,000 PL or post-larvae per run (45 days), although there are entrepreneurs trained in Muñoz who are also operating small backyard hatcheries for prawns.
With the emerging global market on this giant freshwater prawn coupled with improved technologies, it is but imperative to speed up the development of the industry in the country. However, the industry is faced with problems and constraints that include:
• insufficient breeders
• insufficient supply of post-larvae or PL for stocking
• limited market supply
• limited funds for interested stakeholders
• insufficient information
• inadequate promotion of technology transfer
• very few skilled and/or trained technicians
• research and development of ulang hatchery and grow-out are still wanting new technologies
