This volume provides a selection of papers presented at the 15th International Seaweed Symposium in Valdivia, Chile, in January 1995. Plenary lectures featured seaweed research and utilization in Chile by Bernabe Santelices, ethnobotany of seaweeds by Isabella Abbott, host-virus interactions in marine brown algae by Dieter Muller, DNA analysis methods for recognizing species invasion by Annette Coleman, and recent developments in manufacturing and marketing carrageenan by Harris Bixler. Also included are sections on integrated aquaculture using seaweeds and marine invertebrates or fishes and on diseases in seaweeds. The remaining papers cover recent advances in floristics and systematics, population studies, pollution, cultivation, economics, physiology, biochemistry, cell biology, and chemistry and chemical composition of seaweeds, particularly species of Gracilariales, Gigartinales, Gelidiales, Laminariales and Fucales.
