Human use of seaweed is known from the Neolithic period. [4] Cultivation of gim (laver) in Korea is reported in books from the 15th century. [71] [72] Seaweed farming began in Japan as early as 1670 in Tokyo Bay. [73] In autumn of each year, farmers would throw bamboo branches into shallow, muddy water, where the spores of the seaweed would ...
Saccharina japonica is a marine species of the Phaeophyceae (brown algae) class, a type of kelp or seaweed, which is extensively cultivated on ropes between the seas of China, Japan and Korea. [1] It has the common name sweet kelp. [2] It is widely eaten in East Asia. [3]
An alternative offset would be to cultivate kelp forests. Kelp can grow at 2 feet per day, 30 times faster than terrestrial plants. Planting kelp across 10% of the oceans (4.5 x the area of Australia) could provide the same offset. Additionally, the kelp would support a fish harvest of 2 megatons per year and reduce ocean acidification. Large ...
Kombu is a loanword from Japanese.. In Old Japanese, edible seaweed was generically called "me" (cf. wakame, arame) and kanji such as "軍布", [3] 海藻 [4] or "和布" [5] were applied to transcribe the word.

Ascophyllum nodosum is harvested for use in alginates, fertilisers, and the manufacture of seaweed meal for animal and human consumption. Due to the high level of vitamins and minerals that bioaccumulate in A. nodosum, it has been used in Greenland as a dietary supplement. [6] It was also been used for certain herbal teas, particularly kelp teas.
Natural seaweed ecosystems are sometimes under threat from human activity. For example, mechanical dredging of kelp destroys the resource and dependent fisheries. Other forces also threaten some seaweed ecosystems; for example, a wasting disease in predators of purple urchins has led to an urchin population surge which has destroyed large kelp ...
Kelp have had to adapt dispersal methods that can make successful use of ocean currents. Buoyancy of certain kelp structures allows for species to disperse with the flow of water. [21] Certain kelp form kelp rafts, which can travel great distances away from the source population and colonize other areas.
