The study was carried out to reveal the culture and management practice of freshwater prawn (Macrobrachium rosenbergii) in different villages of Abhaynagaer upazila, Jessore, from September 2012 to January 2013. The informations were collected through interviewing 50 prawn fish farmer with a semi-open questionnaire, which include the physical condition of the prawn ghers, pre-stocking management, stocking management, post-stocking management, integrated rice-prawn farming, social condition of prawn farmers, production and cost benefit analysis of polyculture and monoculture system. In study area, most of the prawn farmer practice pond preparation procedure; use Cow dung, Urea, and TSP as fertilizers and snail meat, fish meal, bhusi, rice bran as supplementary feed. About 60% farmers practice polyculture while 35% practice crop-rotation prawn farming and only 5% monoculture of prawn. On an average total income from polyculture and monoculture are 395300 Tk./ha/year and 288000 Tk./ha/year while the expenditure is 241090 Tk./ha/year and 212290 Tk./ha/year. The net benefit was 154210 Tk./ha/year for polyculture and 75710 Tk./ha/year for monoculture and net income rate was 63.97 % and 35.67% consecutively. In study area, fish farmers do not have sufficient scientific knowledge in prawn farming management. So the farmers need to be trained in aquaculture management through aquaculture training programs.
