    Selective breeding program for genetic improvement of Macrobrachium rosenbergii in Thailand. 

    SU Uraiwan & PK Sodsuk - 2005 - Aquaculture Department, Southeast Asian Fisheries Development Center (SEAFDEC/AQD)
    Although the giant freshwater prawn (Macrobrachium rosenbergii) has been domesticated in Thailand for over decades, appropriate selective breeding program has yet to be achieved. Good quality seeds for the Machrobrachium aquaculture industry is therefore not regularly produced. One of the selective breeding programs on improving growth performance of the domesticated strain have been carried out at the Aquatic Animal Genetics Research and Development Institute (AAGRDI), Department of Fisheries of Thailand. AAGRDI has now developed improved and domesticated stock of Macrobrachium rosenbergii for two generations. Meanwhile, domesticated stocks from private hatcheries have also been acquired.

    There is, therefore, the need to develop another improved stock of this species basically from these two domesticated stocks together with a wild stock in order to improve the genetic diversity of the base population for further selective breeding program. Macrobrachium wild stock has been domesticated under hatchery conditions at the AAGRDI for one generation. Generally, a good base population for genetic improvement program requires high genetic variation as well as an ideally suitable stock that can be well adapted for each of different local environments. Therefore, all proper crosses of these three stocks need to be cultured in different areas of the country and then evaluated on both performance and genetic variation before selective breeding program takes place.

    The freshwater prawn research at SEAFDEC/AQD. 

    MR Eguia - 2005 - Aquaculture Department, Southeast Asian Fisheries Development Center (SEAFDEC/AQD)
    Research and commercial production of the freshwater prawn, Macrobrachium sp., in the Philippines are yet not well-developed. Although studies on Macrobrachium sp. (or ulang as it is locally known), started at the Binangonan Freshwater Station (BFS) of SEAFDEC/AQD in the mid-1980s, research efforts were discontinued soon thereafter because of: (a) inadequate technical skills; (b) problems with larval rearing and the domestication of wild stocks; and (c) the Macrobrachium sp. is being considered in the Philippines as a low priority species in contrast to commercially important freshwater commodities like tilapia and milkfish.

    That was two decades ago and in retrospect, researches continued and the freshwater prawn in the Philippines could have been successfully domesticated and current problems concerning the limited aquaculture production of genetically depauperate non-indigenous stocks could have been resolved. With the renewed interest in the culture of alternative species like the freshwater prawn, researchers at the Binangonan Freshwater Station (BFS) started to conduct some studies on the refinement of breeding, larval rearing and culture of Macrobrachium rosenbergii since 2003.

    Freshwater prawn program of BFAR 

    MM Tayamen - 2005 - Aquaculture Department, Southeast Asian Fisheries Development Center (SEAFDEC/AQD)
    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
