This book contains the proceedings of the 18th International Seaweed Symposium, which provides an invaluable reference to a wide range of fields in applied phycology. The papers featured in this volume cover topics as diverse as systematics, ecology, commercial applications, carbohydrate chemistry and applications, harvesting biology, cultivation and more. It offers a benchmark of progress in all fields of applied seaweed science and management.
