Abstract
The present study was conducted in the southwest part of Bangladesh from 2008 to 2009 in order to assess of mud crab fattening practice and its production performance between two different seasons. Generally two crab fattening seasons are observed in Bangladesh, one is the dry or peak season (October to May) and another one is lean season or wet season (June to September). Significant variation in stocking density was observed between two seasons during the study period. Comparatively higher stocking density and higher production was found in dry season in comparison to wet season. The reasons behind higher production and production rate were; the availability of the crabs and high market price for the crabs during dry season. On the other hand, rain fall, occurrence of diseases and natural disaster might be the cause of lower production of crab during wet season. Crab farming and fishery could play a sustainable alternative employment opportunity for the development of coastal people. So government should take some necessary steps for the development of this fishery.Res. Agric., Livest. Fish.2(1): 135-141, April 2015

Summary
Study area The Southwest part of Bangladesh; Khulna, Bagrhat and Satkhira; three districts were selected for this study. Three selected study areas are nearer to Sundarbon mangrove region which is the main source of crab fry for this culture practice. Data collection method A combination of following survey technique was used for data collection. A total number of 150 crab fatteners, 50 for each district were selected and were interviewed throughout the period of study. The interviews were focused on current fattening practice with its production. Fatteners were interviewed on their farms site in both dry and wet period during their production time. Secondary data collection Secondary data based on information collected from some published reports, papers and some official documents and reviews the existing information on the different aspects of the crab fattening in Bangladesh. Data processing and Analysis At each stage of survey, data were checked up, editing, and coding at the field level.
