The coastal and estuarine zone of West Bengal is noted for its rich biodiversity owing to the presence of Sundarbans mangrove ecosystem. However, due to intense industrialization and urbanization, many of the pockets have become ecologically sensitive. The present paper is an attempt to evaluate the Ecologically Sensitive Zone (ESZ) through enumeration of Aquatic Health Index (AHI). In the present programme, three stations in and around Indian Sundarbans namely Canning, Junput and Sagar Island were selected and the aquatic health index value of these stations varied as per the order Sagar Island > Canning > Junput. The lower value of the index reflects deteriorated condition of the coastal water due to excessive industrial, agricultural and domestic run-off. The high values of the index are the indicators of congenial coastal environment.
