The present study deals with the habitat ecology of freshwater molluscan species of wetland of Dhemaji District of Assam. Freshwater molluscs (bivalves and gastropods) were found in a wide range of freshwater habitats, have varied life-history strategies and exhibit complex ecological interactions. Total eleven species of freshwater molluscan species were found in the study. The snail, Brotia costula and the bivalve Lamellidens marginalis were the most ubiquitous species in the study area. The study indicates that the molluscan community could be explored for possible use as food value and ethno-medicinal purpose in the rural area of the people of Dhemaji district, Assam.
Key words: Mollusc, Bivalves, gastropods, food value, ethno-zoology, habitat ecology.
