dc.description.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 control. drainage ami irriga(ion has been inlroduced III Banglaue,h (first phase durmg 1996.2002) hy LGED, This smdy was carricd out w'th the "hjeClivCI of finding om Ihe change in pattern and amount of n,h prodUCII(lndue to implementa(lon of these subproje<;t", e,alualing thc performance of fish t!'lendly ~trudure aml identifying the factors re'pomihle for success/failure ,)1' SSWRDSP. To perform the sludy, four subprojects in Khulna and 5atkhira dlsmct:; hav~ bcen sekcted, The study wa" ~arrieJ Out on th~ basis of both prmlary and secondary diHa.DilTerflll inJicators (In area of f'sherie<;, fi"h 'pecics, fLsllproducllon and f"heTS llavt been LlleJ to evaluatc the performance of ,he subproject, in fi,heries Jcvdopmem.

The number of fi,h cultivators has increased by 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,.

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. en_US
