    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.
