West Bengal is a vast state with a number of agro-climatic zones with their distinctive sociological, economic, political and infrastructural features. Environment of aquaculture development varies accordingly. The intensity of fish culture, access to natural resources, infrastructural facilities, overall political environment are different for different districts. All these factors may have important impact on the performance of a fish farm. In this paper, attempt has been made to access how far such variation affects the levels of technical efficiency of individual farm. Technical efficiency has been calculated using meta-frontier data envelopment analysis (DEA) to identify whether it is possible to construct a summary measure of the efficiency of a region relative to the state as a whole. The data obtained from primary survey on 360 fish farmers in West Bengal, has revealed that medium-sized farmers of red and laterite zone has highest area efficiency followed by new alluvial region; coastal and saline zone; and old alluvial region. Study suggests that the extension and training programme of the government and financial assistance required for progressive farmers, is to be area or community specific, taking into account the different development potentials as well as constraints of each area or community.
