ProjectAgar and Alginate Production from Seaweed in India-BOBP/WP/69 1991
Also available in:
No results found.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. -
Journal, magazine, bulletinThe global status of seaweed production, trade and utilization. Globefish Research Programme Volume 124 2018
Also available in:
This report is an update of the status of the global seaweed market: production figures from culture and capture, the size of the international market for seaweed and its commercially important extracts, the leading nations by region, developments in processing and utilization technology, and innovations in the industry, as well as the challenges and outlook for the industry. As it is not possible to feature individual countries of importance in the seaweed sector, several have been selected as being representative of the different regions of the world: Asia (China, Indonesia, the Republic of Korea, Malaysia, the Philippines, Singapore and Thailand); South America (Chile); Europe (Denmark, the European Union); and Africa (Morocco, South Africa and Zanzibar (Tanzania)). The sections on Chile, China, Denmark and South Africa are based largely on previous studies commissioned by the Food and Agriculture Organization (FAO). -
MeetingAsia-Pacific Fishery Commission (APFIC) Regional Overview of the Status and Trends of Aquaculture in the Asia-Pacific Region 2016 2017
Also available in:
No results found.The aquaculture production in the Asia-Pacific Region during the two year period (2012-2014) is reviewed to see how the aquaculture sector in the region performed during these 2 years. This will allow for the determination of the driving factors that are responsible of the over-all performance of the aquaculture sector. Country production data from the FAO database is the main source of the production statistics used. The over-all performance of the aquaculture sector in the region remained healthy and strong. The region remains the largest contributor to the global supply of fishery products from aquaculture farms supplying 91% of the total global supply of aquaculture products in 2014. As in the previous years, China remained the largest producing country of aquaculture products contributing 63.7 % of the total production in the region, and 58 % to the global supply. Indonesia is fast catching up with its 2014 production up by almost 50% compared to 2012. Other countries that posted modest increase in their aquaculture production between 2012 and 2104 include India (15.9%), Bangladesh (13.4%), Viet Nam (10.2%), New Zealand (9.7%) and Myanmar (8.5%). Although the volume of the production is not much and the production data are all FAO estimates, it is noteworthy to mention that the aquaculture production of Cambodia increased by 62.2% during the 2-year period. Thailand posted the largest decline (26.5%) in its production during 2012 and 2014 largely due to more than 50% decrease in the production of the white leg shrimp as it is affected by a major disease specifically the Acute Hepatopancreatic Necrosis Disease (AHPND or popularly called Early Mortality Syndrome or EMS). The aquaculture production in Malaysia, Philippines and Australia decreased as well by 17.9, 8.7 and 8.4%, respectively. The herbivorous and omnivorous freshwater (FW) fishes like the carps remained the top commodity for culture with production volume in 2014 equivalent to 41.6% of the total fish production in the region. This has increased by 10.7 % over the 2 year period. Aside from the carps, other FW fishes like the tilapias, catfishes and the FW fishes nei also posted significant increase in production. In addition, the seaweeds particularly Eucheuma in Indonesia and Japanese kelp and Gracilaria in the China sub-region showed more than 30% increase in production between 2012 and 2014. On the other hand, the production of white leg shrimp in Thailand and giant tiger prawn in Indonesia suffered significant decline of more than 30% during the 2-year period. It must be noted, however, that white leg shrimp production in other countries like in India and Indonesia remained strong with increase in annual production of more than 50%. Some important issues like the need to prevent outbreaks of diseases in aquaculture farms, the awareness and the commitment among the players to ensure the good health of the surrounding environment where the aquaculture activities are happening, the need to ensure the sustainability of the use of pelleted feeds, and the necessary preparations that have to be put in place for the future warmer climate have to be consistently in the radar screen to ensure the sustainability and the continued growth of the sector, and thereby for humanity to continue reaping the benefits that can be derived from the industry.
