Abstract :

The distribution and diversity of marine molluscs were collected in relation to their species richness and relative abundance in family wise and species wise in different season at five coastal sites in north–east coast of India during June,2011 to May,2014. A total of 63 species of marine molluscs were recorded, among them 31 species of gastropods belonging to 19 families and 23 genera and 32 species of bivalves belonging to 15 families and 24 genera .An increase of species density and diversity in the post monsoon season was observed at maximum selected sites. The maximum density of molluscs fauna was recorded in Bakkhali and Chandipur and highest diversity was recorded in Digha from selected localities during study period. From these localities is a wide chance of research to further explore both on the possibility of commercial purpose and ecosystem conservation.
