“…Nearly all kelp production occurred in Asia: China 88.3%; Korea (south) 6.6%; and Korea (north) 4.4% (FAO 2017). Kelp has been utilized mostly for human consumption, but recently, it also has been increasingly utilized as abalone feed due to low production costs (Hwang et al 2012(Hwang et al , 2013. Since the early part of this decade, Undaria and Saccharina production have continuously increased due to demand for abalone feeds in Korea (Hwang et al 2012).…”

Seaweed aquaculture technologies have developed dramatically over the past 70 years mostly in Asia and more recently in Americas and Europe. However, there are still many challenges to overcome with respect to the science and to social acceptability. The challenges include the development of strains with thermo-tolerance, disease resistance, fast growth, high concentration of desired molecules, the reduction of fouling organisms and the development of more robust and cost efficient farm systems that can withstand storm events in offshore environments. It is also important to note that seaweed aquaculture provides ecosystem services, which improve conditions of the coastal waters for the benefit of other living organisms and the environment. The ecosystem services role of seaweed aquaculture and its economic value will also be quantitatively estimated in this review.

“…Transplantation of Japanese varieties of S. japonica into Korea occurred in the 1960s (Chang and Geon 1970), and selective breeding to extend cultivation periods has recently been undertaken (Hwang et al 2017). Newly introduced species into Korean seaweed cultivation include three green seaweeds, Codium (Hwang et al 2008b), Capsosiphon (Sohn 1998, Hwang et al 2003, and Ulva (Yoon et al 2003, Park and; five brown seaweeds, Ecklonia (Hwang et al 2013), Eisenia, Costaria, Undariopsis (Hwang et al 2011), and Sargassum (Sohn 1998, Hwang et al 2007; and one red seaweed, Gracilariopsis (Sohn 2009(Sohn ). 1977).…”

“…The increasing demand for fresh algae from the abalone industry has provided the opportunity to investigate the culture of these species further. These algae are perennial and continue to grow and produce valuable biomass for abalone feed during the summer when other species of brown seaweed are not abundant (Hwang et al 2013). Gracilariopsis chorda is cultured as human food and is mainly eaten in a steamed salad.…”

Tribute to This paper is dedicated to the memory of Professor Chul Hyun Sohn (1943~2019) Mariculture is regarded as the only option to supply the increasing demands for seaweeds as human food, feeds, fodder, and phycolloids in a sustainable manner. Technologies for culturing a range of seaweed species have been developed successively in Korea since the 1970s. In 2017, Korean marine farms produced 1,761,526 t of seaweed. The key focus of the industry is on the production of Pyropia (523,648 t), Undaria (622,613 t), and Saccharina (542,285 t). Pyropia is economically the most important species in Korea, accounting for up to 68% of total production value. As the top exporter of Pyropia in the world, Korea exported up to US $525 million of Pyropia products to 110 countries in 2018. Other economically important genera include Sargassum, Ulva, Capsosiphon, Codium, and Gracilariopsis, all of which are used for food, and Gelidium, Pachymeniopsis, and Ecklonia which are used as raw material for phycocolloid extraction. Significant work has gone into developing more productive strains of key seaweed species, and in 2012 the Korean government began to certify seaweed varieties. To date, 19 seaweed cultivars have been registered including 13 Pyropia, 5 Undaria, and 1 Saccharina. The industry is now seeking not only to increase productivity but also to add value through processing. Convenience foods and snacks have been developed that target health-conscious consumers and utilize the nutritional properties of seaweeds. The industry is also seeking to promote the sustainability of seaweed farming. One seaweed company in Korea obtained the world's first ASC-MSC (Aquaculture Stewardship Council-Marine Stewardship Council) certification in 2019 and more are expected to follow their lead. With continued research support, the Korean seaweed industry plans to continue to expand to meet new market demands at a sustainable pace.

“…E. cava, is popular as a food ingredient, fertilizer, as an ingredient in folk medicine, and animal feed stock in Korea and Japan (Le et al, 2009). Specifically, E. cava, is commercially cultivated to supply a summer feed for the abalone industry in Korea (Hwang et al, 2012a). E. cava has been identified as a potential source of a wide spectrum of secondary metabolites such as phlorotannins, sulfated polysaccharides, and carotenoids.…”

Seaweeds play a vital role as a source of food and ingredients in traditional Korean medicine. Koreans consume seaweed as fresh vegetables, salad, soups, or snacks. There are several edible brown seaweed species are abundant along the shores of the Korean peninsula, such as Ecklonia cava, Hizikia fusiforme, Laminaria japonica, Pelvetia siliquosa, Sargassum fulvellum, and Undaria pinnatifida. With the growing body of scientific evidence, it is clear that these brown seaweeds are not only good substitutes for land vegetables but also a good source of bioactive secondary metabolites. The secondary metabolites identified from edible Korean brown seaweeds (phlorotannins, sulfated polysaccharides, pigments, and sterols) have the potential to be developed as functional food ingredients. However, seaweeds consumption and their industrial level applications as functional materials are limited compared to the land vegetables. Insufficient awareness about health benefits of seaweeds might be the reason for this issue. Thus, in this review health promotion properties associated with edible Korean brown seaweeds are summarized. The present study might therefore increase consumption and industrial use of brown seaweeds.
