Abstract

The objective of this study was to know the present status and decreasing causes of shellfish diversity in the Passur river of Sundarban, Bangladesh. The study was conducted over a period of five months from October 2011 to February 2012 on the Chandpai range of the Passur river, Sundarban, Bangladesh. A total of 14 shellfish species of three orders and 7 families were identified. On the basis of availability the species were categorized in four statuses that obtained as available (50%), less available (22%), rare (14%) and very rare (14%). Results of the study identified two species as very rare which may extinct near future resulting declination of the shellfish diversity. Few man made decline causes like water pollution, fishing in the sanctuaries, use of set bag and drag net to catch prawn an shrimp fry were observed as major threats for the diversity of shellfishes. The present work recommends preventing water pollution, increasing fishermen’s awareness, implementation of fisheries laws and reduction of using set bag and shore drag net to save the shellfish diversity of this important river of Sundarban, Bangladesh. Besides, counter and random survey is recommended to cross check the shellfish status for their proper management and conservation.
