Management practices and environmental quality of the crab (Scylla serrata) farming ponds in Gosaba and Basanti blocks, 24 Parganas (South), West Bengal has been investigated. Split bamboo fenced rectangular culture units are preferred by over 70% of the farmers with highly variable stocking density. Total inorganic nitrogen and BOD increased with the increasing biomass of the crabs in both the sites. Salinity, total alkalinity and hardness played direct roles in body weight gain and survival rate. Water salinity of 17.50 to 20.0 ppt and hardness upto 1000 mg l-1 were found to be optimal for body weight gain of the cultured crabs.
