“…The breeding procedure for the cultivation period extension of S. japonica in Korea was conducted from 2009 by Hwang et al (2017) in Haenam, Korea (34°38′06″ N, 126°15′57″ E). We named the F 3 generation Sugwawon No.…”

“…Following successful selective breeding research, the Sugwawon No. 301 cultivar has been developed via selective breeding for an extended cultivation period (Hwang et al 2017). The cultivar is being prepared for registration as a Korean government's new variety and will be distributed to fishermen after registration.…”

“…Developments of gametophytebased seed banks and new strains of kelp produced via hybridisation may be critical to help resolve such issues. With these technologies, temperature-tolerant kelp germplasm could be provided to growers in southern New England, similar to what has been done traditionally in Asia (Hwang et al 2017(Hwang et al , 2018(Hwang et al , 2019Zhang et al 2016Zhang et al , 2018. Kelps have been the major seaweed aquaculture species in the United States for several reasons; for example, publicly funded cultivation technologies for nursery and open-water farming have been made available through open-source portals (Connecticut Sea Grant 2014;Flavin et al 2013;Redmond et al 2014a).…”

Seaweed aquaculture is a relatively young industry in the United States compared to Asian countries. Early attempts at seaweed aquaculture in California, Washington State, New York and the Gulf of Maine in the 1980s and 1990s did not result in commercial production but provided important lessons. Since 2010, commercial cultivation of kelp (Saccharina latissima, Laminaria digitata, and Alaria esculenta) and other seaweeds (Palmaria palmata and Porphyra umbilicalis) began in the Gulf of Maine and Long Island Sound. Seaweed aquaculture is now a fast-growing maritime industry, especially in New England. If seaweed aquaculture is to maintain its momentum, it is important to (1) emphasise the environmental benefits; (2) domesticate a variety of local species; and (3) diversify seaweed products for food, animal feed, phycocolloids, cosmeceuticals, nutraceuticals, and ultimately biofuels if it becomes economically viable due to the cost of production. The exclusive economic zone (EEZ) of the United States offers opportunities for expansion of seaweed aquaculture in an area greater than the entire land mass of the United States and with limited user conflicts. This study reviews the past and current status of seaweed aquaculture in the United States and discusses potential opportunities and challenges of open-water seaweed aquaculture.

“…The rapid development of the seaweed farming industry has been supported by technological advancements for seedling-rearing and 'autumn sporeling-rearing' (Sohn 1998). Consecutive selection for three generations (F 3 ) in S. japonica targeted a cultivar with an extended cultivation period (Hwang et al 2017). The cultivar is being prepared as Sugwawon No.…”

The use of seaweeds as human food in eastern Asian countries has a long history, stretching back over a thousand years. However, it was not until the late 1940s that cultivation of seaweeds in near-shore coastal areas began. Due to their location, the Korean peninsula, the Japanese islands and the Chinese coasts share a similar seaweed flora in their coastal waters, and it is not surprising that seaweed species chosen for cultivation, methods of farming and post-harvest processing in these countries have a lot in common. In 2016, the total seaweed production in these three countries reached 16,218,406 t, approximately 53.8% of global seaweed production (FAO). In the course of seaweed farming development in eastern Asia, the development and use of seaweed cultivars have contributed significantly to the seaweed farming industry in terms of improving both the biomass yield and the quality of the food products produced. In this article, the recent development of cultivar-related research and applications practised in Korea, Japan and China are reviewed with particular reference to the key commercial species: Saccharina japonica, Pyropia spp., Undaria spp., Cladosiphon okamurarus, and Nemacystus decipiens. In the past 21 years, 47 certified seaweed cultivars have been used in commercial cultivation in these countries. While much of the development effort has focused on increasing yields, a current emphasis in cultivar breeding programs is to increase the quality of farmed seaweed products. More recently, molecular analyses have been integrated into these programs and have become indispensable tools in the breeding process.
