The Proceedings of the 19th International Seaweed Symposium provides an invaluable reference to a wide range of fields in applied phycology. Papers cover topics as diverse as the systematics, ecology, physiology, integrated multitrophic aquaculture, commercial applications, carbohydrate chemistry and applications, harvesting biology, cultivation of seaweeds and microalgae and more. Contributions from all parts of the world give the volume exceptional relevance in an increasingly global scientific and commercial climate. Like its predecessors, this volume provides a benchmark of progress in all fields of applied seaweed science and management, and will be referred to for many years to come.
