Introduction to Fisheries and Aquaculture  Technologies
             9. Integrated  Duck cum Fish Farming


              oI.  Contact division/person/unit        Freshwater  Station, Bangladesh  Fisheries  Research
                                                       Institute, Mymensingh.
              02.  Location of application             In any pond which is not flood prone.
              03.  Key characteristics of the      a.  Produces  enough  fish food organisms  in the pond
                   technology                          because of discharge of fresh duck manure.
                                                   b.  No supplementary feed is necessary for fish.
                                                   c.  Minimize  space through construction  of duck shed
                                                       over the pond.
                                                   d.  Maximize production with minimum land & inputs.
              04.  Production guidelines
                   Pond selection and preparation  a.  Perennial pond is preferred. Dyke should be repaired,
                                                       liming @ 1 to 1.S kg/decimal is done & predators are
                                                       controlled.
                   Stocking                        b.  @ 6000 fingerlings  (S-IO ern size)/ha.  Ratio  of
                                                       different  carps in the population  are surface feeder
                                                       40%, column feeder 30% and bottom feeder 30%.
                   Construction of duck shed       a.  The recommended  floor space for one duck is 2.1 sq.
                                                       meter.  Wide  space  111 between  slits  of floor  to
                                                       facilitate duck manure dropping into the pond.
                                                   b.  Duck house height should be 1.2-1.Sm from the floor.
                   Duck rearing                    a.  Type of duck should be khaki cembell/Indian runner.
                                                   b.  Density SOO/haof pond.
                                                   c.  Feeding with supplementary feed.
              OS.  Risk involvement and            a.  Theft of duck/fish to be checked.
                   management in adopting the      b.  Flooding should be checked.
                   technology
              06.  Impact of environment           a.  No adverse effect on aquatic environment.
                                                   b.  Recycling of duck dropping into fish food organisms
                                                       keep the pond soil and water quality intact.
              07.  Procedure of transfer           a.  Training.
                                                   b.  Demonstrations.
                                                   c.  Extension services.
              OS.  Expected outcome                a.  Increase fish production and income generation.
                                                   b.  Help in rural economy and development.
                   Benefit and cost involvement        Total cost: Tk. 1,66,SIS/ha.
                                                       Total income: Tk. 3,27,326/ha.
                                                       Net Benefit: Tk. 1,60,SII/ha.
 [            09.  Recommendations                     This technology  should be transferred  to the rural
                                                       poor through GOINGO agencies.
