“…Seaweeds denote thousands of species of macroscopic, multicellular, marine algae, such as Chlorophyta (green) ,Rhodophyta (red) and Phaeophyta (brown) (1,2). Importance of seaweeds in provision of ecosystem services are known, for example species such as kelps provide essential nursery habitat for fisheries and other marine species and thus protect food sources (3); species of algae, play a vital role in capturing carbon, producing up to 50% of earth's oxygen (4).…”

“…Management of naturally found batches of seaweeds mainly conducted in its simplest form and full controlling the life cycle of the algae in most advanced form of farming (6). Widely cultivated seaweed taxa are Eucheuma spp., Saccharina japonica, Sargassum fusiforme, Gracilaria spp., Pyropia spp., Undaria pinnatifida andKappaphycus alvarezii (1). Seaweeds are farmed for different applications, for example Gracilaria is farmed for agar production; Eucheuma and K. alvaraezii are farmed for gelling agent (carrageenan); while the rest are for food (7,8).…”

Seaweed farming in the Western Indian Ocean (WIO) is among the income-generating activities; apart from seaweeds being primary producers, they are foundation species important for marine ecosystem capable of modifying their surrounding abiotic and biotic environments. The WIO coast provides natural and necessary environments for seaweeds farming. In this review article seaweed farming in WIO was investigated; its contribution to provision of ecosystem services; medicinal and nutritional value; role of women; challenges and the wellbeing of farmers and the whole ecosystem. It was observed that among the challenges facing seaweed farmers include lack of modernized farming tools hence farmers use low depth areas leading to attack by diseases, death of seaweed, low yields, and income. Farmers has been reported to be affected by diseases which may be contributed by inadequate of use of protective gears, indicating the need for knowledge on personal protection. This may be contributed by lack of knowledge which leads to farmers participation without using protective equipment leading to contamination from toxic chemical compounds from seaweed, epiphytic bacteria or harmful algal bloom and absorbed heavy metals from seawater as a result of long-term exposure. Farming practices such as uprooting of seaweeds during farm preparation have been observed to cause degradation and decrease fish population. Therefore, there is the need for use of modern technologies; supervision of these activities by professionals in the field, and provision of knowledge to farmers for the sustainability of WIO marine ecosystem.
