Fish Culture Practice and Socio Economic Status in Northern Middle Part of Bangladesh

The present study was carried out in Bhaluka upazilla, the northern middle part of Bangladesh to observe the culture technique of fish culture using of supplementary feeds and socio-economic condition of the fish farm owners. Data were collected from 39 fish farms in Bhaluka upazilla during the period from September 2010 to August 2011. Most of the studied farm owners carried out polyculture system and culture, mostly carps (Indian major carps and exotic carps), pangus and tilapia using supplementary feeds. The feeding rate varied from 1-7% of body weight of fish with frequency 1-3 times/day. The highest production was recorded as 56,810 kg/ha/yr using company feed and the lowest production was recorded as 14,210 kg/ha/yr with an average production of 34,350 kg/ha/yr. The average production of 23,520 kg/ha/yr was recorded (farm made feed). Most of the farmers did not use fertilizer and manure in their ponds, but in winter season sometimes they used poultry litter to avoid high priced feed. The overall management practice was not smoothly developed in the monoculture and polyculture farms. It may be concluded that we have to reduce all of the constraints of management practices of aquaculture to achieve sustainable growth in future aquaculture of Bangladesh.
