    Social and economic dimensions of carrageenan seaweed farming

    Carrageenan is a gelling agent extracted from red seaweeds and it has multiple applications in the food processing and other industries. Increasing demand for carrageenan has led to rapid expansion of carrageenan seaweed (primarily Kappaphycus and Eucheuma) farming in tropical areas. This expansion is expected to continue, but many issues need to be addressed to enable the sector to develop its full potential in contributing towards sustainable livelihoods, human development and social well-bein g. Including six country case studies and a global synthesis, this document provides a comprehensive and balanced assessment of the economic, social and governance dimensions of carrageenan seaweed farming. Information and insights provided by this document should facilitate evidence-based decision-makings in both the public and private sectors.

    The rediscovered potential of seaweed dietary additives 2022

    The cellular structure of seaweeds comprises indigestible fibres or complex polysaccharides, which are used as thickening additives or gelling agents in a range of processed foods and in cosmetics, pharmaceuticals, nutraceuticals and other industries. To date, only a handful of seaweed species have been used commercially as animal feed additives. Two main reasons underpin the use of seaweeds as dietary additives are to bolster the immune system of farmed animals and to improve their productivity and meat quality. Southeast Asia could play a significant role in the production of tropical seaweeds for animal feeds. Due to the vast number of seaweed species, novel seaweed additives, with the potential for animal production, are being discovered.

    Agar and Alginate Production from Seaweed in India-BOBP/WP/69 1991

    Although small by world standards, Indian production of agar and alginates— natural gums derived from certain species of seaweed — contributes to the national economy by supplying materials to the market that would otherwise need to be imported. It is also important in providing income opportunities to many fishing communities, particularly the women, who harvest the seaweed from coastal waters. This paper surveys the Indian seaweed industry and its principal products, agar and sodium alginate . Technical and economic aspects of seaweed collection and processing, and the markets for the products, are examined. Trials undertaken by BOBP to cultivate Gracilaria seaweed and to employ it as a source of raw material for villagescale agar production are briefly described. The work presented is based on information collected during visits made in 1988 and 1989 to harvesting centres along the south-eastern coastline of Tamil Nadu, Kerala, Andhra Pradesh and Gujarat. The seaweed industries a re not well documented and the report relies heavily on first-hand information gained through visits and discussions with the seaweed collectors, agents and processors. The authors would like to thank all these people for their kind assistance during the implementation of this study as well as the Post-Harvest Fisheries Adviser and local consultants involved in the collection of data and the organization of this visit. The work described in this paper has been sponsored by BOBP’s Post-Harves t Fisheries Project. It is executed by the Natural Resources Institute (NRI), UK, and funded by the ODA (Overseas Development Administration) of the United Kingdom.
