“…Production of propagules of eucheumatoids produced from spores has not yet been adopted for commercial cultivation. This compares unfavourably to investments made in the commercial cultivation of cultivated seaweeds such as Hizikia (Pang et al 2005, Ecklonia (Hwang et al 2009), Palmaria (Pang & Lüning 2006) (Hwang et al 2006;Pang et al 2009) and Undaria (Hwang et al 2011(Hwang et al , 2014 which have variously produced gametophytes and sporophytes for seedlings, as developed from sexual or asexually derived spores (i.e. meio-or mitospores).…”

Kappaphycus and Eucheuma, known collectively as 'eucheumatoids', are two related genera of red seaweeds which currently lead the rankings for volume of global production of farmed macroalgae. Since 2009, the combined cultivated volume of these carrageenophytes overtook that of the brown seaweeds Laminaria (Saccharina) and Undaria for global production tonnages, according to statistics of the Food and Agriculture Organization of the United Nations (FAO). The Southeast Asian region, particularly Indonesia, the Philippines, Malaysia, Tanzania, and East Africa are the major producers of eucheumatoid biomass. Despite several success stories of red seaweed cultivation and the economic and socioeconomic value of their ecosystem services, there remain a number of salutary lessons to be learned from 'agronomic' practices applicable to their extensive cultivation. These case studies should be further developed, analysed, and adopted as best-practice recommendations for future socioeconomic prosperity, as well as both economic and environmental sustainability. In this review, we propose the use of the term 'phyconomy' (i.e. large-scale production of marine macroalgae for economic and industrial purposes) as an alternative to the term agronomy (i.e. terrestrial plant production).

“…These were then dried in dark and humid conditions for 1 h. The sorus subsequently released zoospores when it was reimmersed in seawater. Sterilized seed fiber segments (polyvinylchloride fiber, 4 cm in length, 1.43 ± 0.12 mm in diameter) were used for zoospore seeding instead of seed frame normally used for kelp cultivation in Korea (Hwang et al 2014). Seedlings of Sugwawon No.…”

“…Some success has been achieved by rearing hybrids of U. peterseniana (Kjellman) Okamura (male) and U. pinnatifida (female) to provide algal biomass for abalone when U. pinnatifida is not readily available (Hwang et al 2011(Hwang et al , 2012. This hybrid continued growing even after the growth of U. pinnatifida ceased in April (Hwang et al 2014a). Trials showed that the hybrid not only provided an extended production period, it also provided greater biomass than U. pinnatifida.…”

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.
