No Thumbnail AvailableProjectSurvey of commercial seaweeds in South-East Viti Levu (Fiji Islands)
A preliminary study on farming potential of seaweed species present in Fiji
1999Also available in:
No results found.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. -

Regional Seafarming Development and Demonstration Project
1990Also available in:
No results found.Gracilaria is a group of warm water seaweeds. There are more than one hundred species in the world, some of which have very important economic value. Gracilaria is used as food and in the preparation of food products. It is also an important raw material in agar-agar production. At present, the world's annual output of Gracilaria is about 30,000 tons, dry weight, most of which comes from natural production. For example, the natural production in Chile, Argentina, and Brazil accounts for one thir d of this total output. With the increasing demand for Gracilaria, greater attention has been focused on the development of its artificial culture by many countries, especially those in Southeast Asia. China is the earliest country that artificially cultured Gracilaria. Today, the culture area in South China is about 2,000 ha producing 3,000 tons dried material annually. Taiwan produces 1,000 tons dried Gracilaria yearly from 400 hectares under cultivation. Nowadays, Gracilaria is cultured mai nly using the following methods: bottom culture, raft culture, stake-rope culture and pond culture. Pond culture can be divided into two systems, monoculture and polyculture with shrimp and other species. The varieties of culture methods can be adapted for different areas. In view of the importance of Gracilaria as a seafarming commodity, the National Coordinators of the Regional Seafarming Project recommended the dissemination of its culture and processing technology, through a regional train ing and demonstration activity, as a means to further increase the opportunities to develop the seafarming industry of the region. This manual has been prepared for the training course on Gracilaria culture under the Regional Seafarming Development and Demonstration Project (RAS/90/002) to be held at Zhanjiang Fisheries College, Zhanjiang, China in August, 1990. -
