5. Current trends in use of open waters for
aquaculture production
o Rapid development of aquaculture technologies,
improvement in supply of inputs and increase demand
of fish
o Decrease in fish production from open waters created
demands on use it for fish culture
o Increase trends to use floodplains, beels for fish culture
like pond
o Cage and pen culture in river, canal and floodplain
o Construction of road and highway, embankment
accelerate the process due to advantages

6. Fish culture in floodplains and impacts
o Stocking of exotic and endemic carps at high densities
o Removal of small fish and not allow natural fish to enter
from outside
o Removal of aquatic vegetation
o Restricted access of users for fish and other uses
Useful to get higher fish production but negatively impacts
on access and benefits of the users, ecosystem services
and aquatic biodiversity

7. Outline of the Presentation
o Aquaculture System in i open waters (floodplain) using
Community Based Fish Culture (CBFC) and Integrated
Floodplain Management (IFM)Approaches Integrating with
small fish (CGIAR funded PN35 and RIU PN35 Projects)
o Abrief onAquaculture System in closed waters - small
homestead ponds involving women in poor farming households
(IFAD funded small fish and nutrition project and CSISA-BD
project of WorldFish NW], CSISA-BD andAIN Projects in region
of Bangladesh.

8. Community Based Fish Culture in Floodplains
o Ensure access and increase
benefits of the users of
floodplains especially the poor
including fishers
o Use CBFC/IFM approach -
establishment of good
governance
o Develop strategies on
stocking and management of
fish fingerlings

9. Stocking large fingerlings of suitable species at
optimum density and combination in the floodplain

10. CBFC in floodplains – strategies to increase
production of small fish
o Stock enhancement by stocking broodfish of small fish
‘mola’, use innovative techniques in collection,
transportation and stocking of small fish as live
o Use conservation and regulation measures - establish
sanctuaries, improve habitat useful for the fish at different
stages of life cycle
o Use simple devices in the inlets and outlets of the
floodplains to ensure access of small fish avoiding the
escape of large carp fingerlings
o Regulation in use of large gears during the breeding
season effective to get higher production of un-stocked
small fish

11. Stocking of mola brood in Bhelakoba floodplain,
Sadar, Gaibandha after collection and
transportation from Rangpur

12. Use CBFC/IFM to get increase production of small
fish
o Use effective strategy to harvest
small fish together with stocked fish
by allowing to grade without any
stress
o Use effective strategies to
harvest and sale small fish based
on local market demand
o Use IFM approach to grow crops
which demand less water, involve
poor women in such crop production
to get benefits directly
o Use water in ditches of
floodplains saved to conserve
small fish

15. Regular harvest of mola and other small fish from
the floodplain
o Regular harvest of mola and
other small fish from the floodplain
making cash flow and supply of
fish for household consumption
o Continued employment of poor
members involved in fishing (11
for Kola Beel floodplain in
Bagmara, Rajshahi and 5-6
people involved in selling of fish in
market)
oSupply small fish regularly in
local markets useful for local
consumers including the poor

16. Good harvest of fish from floodplain generated local
employment for the poor involved in market value chain

17. Fish production from Bhelakoba
floodplain, Sadar, Gaibandha in 2012

Bhelakoba Floodplain in 2012

Sadar, Gaibandha in 2012
Figure 3 & 4 Income from stocked fish and un-stocked fish (Taka)
earned from Bhelakoba Floodplain in 2012

19. Challenges of CBFC
Increased fish production and income but
discontinuation of the activities in few floodplains
occurred due to:
o Dominance of the Leader
o Inequity in distribution of benefits
o Lack of transparency in investment and distribution of
income
o Poor coordination of Leader with other members
Managing Committee of the CBO

20. Use of closed waters for aquaculture production
o Pond, seasonal waters under fish culture, ox-bow lakes
and shrimp farms are under closed waters
o Fish culture done under semi-intensive, intensive and
extensive systems
o Intensive mono-culture of commercial fish species using
industrial feeds
o Semi-intensive - use of fertilizers and supplementary feed
using polycutlure
o Small fish removed and not allowed to enter in ponds
considered as constraints to get good production
o Small fish has high demand to people and with good
market price

Carp polyculture in ponds of small scale farming households in NW
Bangladesh : communities and households selected for the study

23. o Does the small seasonal ponds of poor farming households is effective to
produce small fish along with carps polyculture?
o To what extent the production of small fish (mola) with having high market
price has been taken by the poor farming households regularly for household
fish consumption and how it is make important to use by pregnant women,
lactating mother and minor children of poor households ?
o What are the innovative things useful to understand and to follow in getting
success in culture of carp with small fish?
o What is needed to disseminate carp polyculture with small fish to other
farming households in shortest possible time?
