Abstract:
The complex community of fj<;h~pecies in Bangladesh is Ilighly dependent on sea"onal
inundation and on 1100dplain access, both of which can be negatively affccltd by flood
Contl'Ol, Drainage and lrrig.ation (feD!) project. %WRDSP, with thc aim of 1100d

Unlike capture fi~hery, the cultutc fisheries In mOIlof the subprojects have increa,ed due
to Implementallon of the project. Tmal fIsh pmduetion of Khorda Baor has mcreased by

'l"h~ number of t1sh cullivalor, of all thc projects has inereaseJ but thc number of

20-85 persons during the p~rioJ 1999.2004. Wherea, lhe number of pan-time and full
lime fishernlen has Jecreased by JO-50persons.
The concept of fish friendly structLlre was adopted in the regulalOr of KIlo,da Bam
subproje,t to safeguard ilS open waler fisherie,. Iniliaily good rerum (If lhis structure was

the pf()jecl since 2003,
The water qualilies of !he four subprojects studied are suitable for fi,h cultivation except
in Narayankhali FCD subproject, which ha~ experienced severe industriai water POiIUlion
for the last few years. The extreme low DO ievel of this subproject has drasticaily iimited
the yield of fishes.
Some suggestions regarding to !he dcveiopmem of culture fishery and protection of the
fishers and capture fishery have also been included in this study.
