Marine bivalves are a group of mollusks that have a body enclosed by a hinged, two-part shell. These organisms include scallops, oysters, clams and mussels. They play a vital role in restoration and sustainable development as they naturally filter water, remove pollutants and improve water clarity, which benefits the entire marine ecosystem. They are found in various environments, from shallow coastal waters to the deep sea. Bivalve farming is a sustainable way to produce seafood, providing a healthy food source without depleting wild populations. Furthermore, these farms contribute to the protection of coastlines by preventing erosion and minimising storm damage, ultimately strengthening coastal resilience. By investing in bivalve restoration and sustainable farming, we support cleaner waters, healthier marine environments and robust local economies. This book provides comprehensive insights into the field of marine science. It unfolds the innovative aspects of strategies to restore and sustainably manage marine bivalve populations which will be crucial for the holistic understanding of the subject matter. This book is a complete source of knowledge on the present status of this important field.
