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 floodplaino Construction of road and highway, embankment

accelerate the process due to advantages

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

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 A brief on Aquaculture 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 and AIN Projects in region of Bangladesh.

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

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

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

Stocking of mola brood in Bhelakoba floodplain, Sadar, Gaibandha after collection and

transportation from Rangpur

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 stresso 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

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

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

Income from fish production in Bhelakoba floodplain, Sadar, Gaibandha in 2012

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

Challenges of CBFC

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

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

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?
