This book delves into various categories of fisheries resources pelagic, demersal, oceanic, deep-sea, crustacean, molluscan, and seaweed fisheries alongside discussions on major fishing gears and crafts employed in Indian marine fisheries. It also highlights contemporary concerns such as bycatch, ghost fishing, the role of Turtle Excluder Devices (TEDs), and the implementation of ecosystem-based fisheries management.With an emphasis on sustainability and conservation, the book explores issues related to illegal, unreported, and unregulated (IUU) fishing, overexploitation, and transboundary conflicts in marine fisheries. Additionally, it provides insights into fisheries policies, international regulatory instruments, and mechanisms essential for effective fisheries governance. Designed to serve as a reference guide for academia, industry, and regulatory bodies, this book is a valuable resource for anyone involved in the study and practice of marine fisheries management.'
