Book (stand-alone)The farming of seaweeds 2012
Also available in:
No results found.Through this booklet the author aims to build, step by step, a clear understanding of the methods and techniques for the farming of Spinosum and Cottonii seaweed. The booklet also describes the range of difficulties and challenges that are likely to be faced , such that the stakeholders (including the farmers, private sector investors, government, donors and NGOs) are able to benefit from past experience and achieve a win-win situation. With this understanding and shared experience, it will be f easible to develop, in partnership with coastal communities, an industry worth millions of dollars. -
Book (stand-alone)Genetic resources for farmed seaweeds
Thematic background study
2022Also available in:
No results found.The increasing global population needs to source food from the ocean, which is a much greater area than the land. The ocean is rich with diversified flora and fauna, and both are sources of proteins, vitamins, minerals, phytohormones, and bioactive compounds. Thousands of species of macroalgae (seaweed) dominate the vegetation of the seafloor from the intertidal to the subtidal zone. The domestication of several economically important seaweed such as Saccharina, Undaria and Pyropia in China, Japan and the Republic of Korea, and Kappaphycus and Eucheuma in Indonesia, Malaysia, the Philippines and the United Republic of Tanzania led to the intensive commercial cultivation of these seaweeds. Except for the United Republic of Tanzania, the commercial farming of seaweed, both temperate and tropical species, is centred in Asia. Despite the presence of several economically important seaweeds outside Asia, commercial farming is practised only in a few of non-Asian countries. These include Chile for Gracilaria and Macrocystis (Buschmann et al., 2001); France for Palmaria palmata, Porphyra umbilicalis and Undaria pinnatifida (Netalgae); and Canada for Saccharina latissima in integrated multi-trophic aquaculture (IMTA) (Chopin et al., 2013) and Chondrus crispus. Trial cultivation of Saccharina spp. and P. palmata is now taking place in Western Europe. Seaweeds are farmed mainly for food such as sea vegetables and food ingredients (Bixler and Porse, 2011), as well as feed (Wilke et al., 2015; Norambuena et al., 2015). However, there is increasing interest in their use for biorefinery products that require a vast amount of biomass which must be farmed. -
ProjectSeaweed ( Gracilaria Edulis) Farming in Vadalai and Chinnapalam, India-BOBP/WP/65 1991
Also available in:
No results found.This paper describes some trials with seaweed (Gracilaria edulis) farming in the open sea. These trials were carried out between 1987 and 1990 in Vedalai and Chinnapalarn, two coastal villages in Ramanathapuram district, Tamil Nadu, India. The purpose of the trials was to discover whether the collectors of wild seaweed in the area could augment their income by cultivating seaweed and, thereby, also possibly preserve their natural resource, which is believed to be diminishing through over-exploit ation. The trials were undertaken by the villagers themselves, with support from the Bay of Bengal Programme (BOBP) and the Tamil Nadu Department of Fisheries. The seaweed farming project, and this paper which reports on it, have been sponsored by BOBP’s “Small-Scale Fisherfolk Communities in the Bay of Bengal” (GCP/RAS/118/MUL), a project jointly funded by SIDA (Swedish International Development Authority) and DANIDA (Danish International Development Ageniy) and executed by FAO (Food and Ag riculture Organization of the United Nations). Parallel with the culture trials, attempts were made to introduce simple agar processing technology at village level and this is described elsewhere. That work was carried out but the Post-Harvest Fisheries project of BOBP which is funded and executed by the ODA (Overseas Development Administration) of the United Kingdom. The BOBP is a multi-agency regional fisheries programme which covers seven countries around the Bay of Bengal Bangladesh, India , Indonesia, Malaysia, Maldives, Sri Lanka and Thailand. The Programme plays a catalytic and consultative role: it develops, demonstrates and promotes new techniques, technologies or ideas to help improve the conditions of small-scale fisherfolk communities in member-countries.
