3. INTRODUCTION
  • Bangladesh is a small country with large
    populations
  • Poverty reduction Central Theme of national
    policy
  • Agricultural land area constantly declining
  • Farmers need income increase from their limited
    and shrinking lands to meet minimum necessities
    of life
  • Freshwater prawn Macrobrachium rosenbergii
    farming has emerged as a significant economic
    activity in rural Bangladesh since early 1990s
  • Prawn farming quickly expanding

4. PRAWN FARMING QUICKLY EXPANDING

5. FACTORS ENCOURAGING PRAWN FARMING EXPANSION
  • Compatible with agriculture
  • Small farmers can practice in their own land
  • Opportunities for womens involvement
  • No interference with mangrove or environment
  • Safer not susceptible to WSSV disease or
    frequent tidal bores as in marine shrimp
  • Can be normally grown in salinity up to 8 ppt
  • Large suitable areas all over the country

6. PRAWN FARMING REDUCING POVERTY
  • Prawn farming reducing poverty in many areas
  • More than 80 of the farms less an acre and
    handled by small farmers
  • Large numbers of mono-crop low-yielding paddies
    now converted into farms producing high priced
    prawn and fish in rotation with paddy
  • Pond embankments grow vegetables and fruits
    fetching extra income and providing better
    nutrition
  • Womens directly involved in increasing family
    income

7. SPECIES, FARMING AREAS AND EXPORT
  • Out of over 20 species of prawn, only
    Macrobrachium rosenbergii is cultured
  • M. rosenbergii is the second most important
    cultured crustacea after marine black tiger
    shrimp Penaeius monodon in Bangladesh
  • Culture area 35,000 40,000 ha covering 15
    20 of total crustacean farms of about 200,000 ha
  • Principal prawn farming areas are in the
    southwest
  • 15 (US54 mill.) to total export earning of US
    362 million from shrimp and prawn in 2003-2004

9. SOME CURRENT PROBLEMS
  • Inadequate PL supply Currently 350 million PL
    used
  • Hatcheries supply only 30 mill PL most PL from
    wild
  • Culture mostly dependent on rain water no
    assured perennial water supply or drainage
    network
  • Short time PL availability restricts culture
    period
  • Available commercial feeds are either of
    inadequate quality or are too expensive
  • Poor nursery practices
  • Declining wild brood-stock population due to
    over-fishing

10
10. DEVELOPMENT NEEDS
  • Farm water supply and drainage infrastructure in
    farming areas under local level Master Plans
  • Extended hatchery operation to extend farming
    from the existing July - November to
    February-November
  • Increased PL production corresponding to needs
  • Cheap but effective feed availability
  • Nursery raising of male juveniles including
    over-wintered juveniles to raise two full crops
    of prawn
  • Conservation of wild brood prawn stocks for
    hatcheries
  • Extension materials for all stakeholders on GAP,
    food safety, environment and social issues
