PREPARATION OF THIS DOCUMENT

This paper is one of a series of studies of major fisheries commodities being undertaken by the Department of Fisheries, FAO. The present paper examines the world's major resources of marine algae, their utilization, trade and potential for further development. Other studies in this series are FAO Fish.Tech.Pap., (126), Production, Trade and Consumption of Small Shoaling Pelagic Species (Naylor, J., 1973); FAO Fish.Circ., (340), Production, Trade and Consumption of Cephalopods and Cephalopod Products (Hotta, M., 1976); and (in preparation) papers dealing with other molluscs, canned products, cured fish, and Japanese market prospects for selected imported fishery commodities.

There is a considerable wealth of literature on the biology, ecology and chemistry of seaweeds but the economic and commercial aspects of the seaweed industry have been comparatively neglected. The published data on the production and use of seaweeds and their products are, in many cases, very limited and, whilst in the preparation of this paper every attempt has been made to obtain and analyse all the official and other data available, the picture remains incomplete. Readers are, therefore, kindly invited to send any comments or proposals for addition, correction or amendment to the author.
