    Seaweed ( Gracilaria Edulis) Farming in Vadalai and Chinnapalam, India-BOBP/WP/65 1991

    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.

    Social and economic dimensions of carrageenan seaweed farming
    FAO Fisheries and Aquaculture Technical Paper No. 580

    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.

    Understanding diseases and control in seaweed farming in Zanzibar 2020

    In view of all production and productivity problems the seaweed aquaculture industry has been facing as well as the impact of the seaweed die-off on the Island economy with sharp decline of income and revenues for thousands of farmers and traders and, recognizing the compounded problems that about 20,000 seaweed farmers' livelihood are based on a single aquaculture system affecting mostly women and youth, the FAO-funded Technical Cooperation Programme “Support to the Aquaculture Subsector of Zanzibar” (TCP/URT/3401) recognized and recommended the Biological and Economic Research on Seaweed as a relevant pillar of the Aquaculture Development Strategy Plan. This technical report is part of the FAO-TZ project “Support to Seaweed Diseases and Die-off Understanding and Eradication in Zanzibar” TCP/URT/3601/C1, and covers an initial analysis of the die-offs due to epiphyte infestation and ice-ice disease in Zanzibar. The assessment is mainly based on site visits to the seaweed farms in Unguja and Pemba and laboratorial analysis of collected seaweed samples conducted by the authors between February and June 2017. Findings were cross-checked with a literature review on the topic and presented during stakeholders’ meetings in both Islands.
