Indian aquaculture sector plays a significant position in the socio-economic improvement of the country, in view of its potential contribution to national income, nutritional security, employment opportunities and export earnings. The study has estimate the growth performance and decomposition analysis in area, production and productivity in aquaculture production of new exportable species in West Bengal during the period 2013-14 to 2020-21. The highest annual growth rate was found Sea Bass (91.96%) in production followed by Pangasius (87.72%) in Productivity and Sea Bass (78.12%) in area respectively. The significant development in area of culture in Tilapia by 41.44% in study period. The decomposition analysis of growth suggests that for Pangasius and Crab culture Productivity effect is the major source of growth in study period and Sea Bass and Tilapia for which area effect was the major source. That is source of output growth for Pangasius and Crab was the productivity effect; for Sea Bass and Tilapia, the growth source was the area effect. The change in mean productivity was primary source of growth in Pangasius and crab. Similarly, the change in mean area was major source of growth in Sea Bass and Tilapia in West Bengal during study period. The change in productivity variance contributed maximum to change in variance of crab production in all other aquaculture species, followed by Interaction between change in mean area and productivity variance.
