Laminaria was harvested for food and 1949 yielded 40.3 metric tons of dry weight. [9] Laminaria need cold water to survive and can only live above 36° N latitude. [citation needed] In 1949, the Chinese started to commercially grow laminaria as a crop. This increased the production of dry weight to 6,200 metric tons.
One is that it originated from the on'yomi (Sino-Japanese reading) of the Chinese name 昆布 (kūnbù). [8] The kanji itself already could be seen in Shōsōin Monjo (8th century) and Shoku Nihongi (797) in Japan, and furthermore trace back in China, as early as 3rd century, to the book Wupu Bencao (around 239).
