Molluscs are the second largest phylum of animals, next to the arthropods. Majority of molluscs are marine, although many also occupy freshwater and terrestrial environments. The molluscs constitute a significant part of the world fishery today. This book is a outcome of a research report that describes the abundance, uses and marketing system of mollusc in the coastal region of Bangladesh. Questionnaire interview, participatory rural appraisal tools, market visit and case studies have been employed to generate data. It identifies a range of mollusc species that have been exploited at the Bangladesh coast and investigates their utilization for edible and non edible purposes. It also provides a comprehensive analysis of different stakeholders in the mollusc distribution chain. This book is useful for students and researchers in biological and fisheries sciences.
