Synopsis (short abstract) The publication describes the production, properties and main applications of the three major phyco-colloids extracted from seaweed: agar, alginate and carrageenan. There is also a supplementary chapter on the preparation and marketing of seaweeds as food. Although this is based mainly as Japanese experience it is included in order to encourage increased consumption of seaweeds as human food. The authors of the three phyco-colloid chapters have considered raw material sources, post-harvest tr eatment, methods of extraction, chemical composition of the colloids, evaluation of quality, and uses, with some details of economics and marketing.

    Case study of seven commercial seaweeds resources 1987

    Seven case studies are presented on commercial seaweed resources; five on wild crops, respectively Ascophyllum nodosum, Chondrus crispus, Gelidium, Laminaria longicruris and Macrocystis , are provided along with case studies of the farmed crops of Eucheuma and Laminaria japonica . Individually the cases range from descriptions of the wild crops and their management to the managed production of farmed crops including, in several examples, some information on economics and/or processing. These ini tial seven cases range from those emphasizing but one species from but one part of one country, to studies of a genus as it occurs commercially throughout the world.

    Survey of commercial seaweeds in South-East Viti Levu (Fiji Islands)
    A preliminary study on farming potential of seaweed species present in Fiji
    1999

    Several seaweed species found in Fiji have economic potential as sources of industrial phycocolloids, judging from reports for closely-related species in overseas countries. Some of these species are already used as food in Fiji and are a commodity traded in municipal markets. This survey was planned to determine, in preliminary fashion, the distribution, abundance and seasonality of economic seaweeds in South-East Viti Levu, and find out whether there would be any demand for them as sources of phycocolloids. The most common economic seaweeds found in Suva Harbour and Tailevu during this survey were Gracilaria maramae, Gracilaria edulis, Hypnea pannosa and Caulerpa racemosa. Other common seaweeds found in the localities visited included Acanthophora spicifera, Laurencia spp., Gelidiella sp., Enteromorpha spp., and Sargassum sp. Occasionally plants of Solieria (an edible seaweed) and Kappaphycus alvarezii (an exotic species introduced from Phillipines that was farmed in Tailevu up unt il 1993) were also found, but were not common. Gelidium pusillum has been previously reported as present in Suva Harbour in small quantities. Hypnea nidulans is common on some back-reef areas. Near Serua Island four types of Gracilaria were found; G. maramae, G. edulis, G. arcuata var. snackeyi, and a possibly new, undescribed species.
