Abstract

The state of art of traditional practice of mud crab fattening was evaluated in terms of technical and economic aspects from 10 randomly selected fattening farms at Paikgacha, Khulna during April to December 2001. Most of the farmers fatten lean (empty egg and/or hepatopancreas) female mud crabs of 180-200 g individual biomass that were rejected during grading at local crab landing centers for two weeks using low coast tilapia and/or trash fish at a rate of 5-8% of stock biomass. Stocking of lean females and harvesting of ripe females were found to be a continuous process and depended on the supply of lean individuals at reasonable prices. Thus, maintaining a fixed stocking density was not observed. The survival and production rate in were recorded at 78.55±12.08% and 0.304 Kg m^-2 respectively. The net income of a farm with an average size of 310.77 m^-2 was recorded at Tk. 21,525 yr^-1.
