The farming of the seaweed cottonii, Eucheuma striatum, began in the Philippines in the 1960s under the auspices of the University of Hawaii, USAID and Marine Colloids, a US carrageenan firm. However, mariculture started seriously only in 1973 when a cultivar was discovered by a Sitangkai farmer called Tambalang.
This variety was later recognized as a totally different species (and genus) and renamed Kappaphycus alvarezii var. tambalang in honor of Mr. Vicente Alvarez, a biologist of the Bureau of Fisheries and Aquatic Resources who became the first Manager of Marine Colloids and Mr. Tambalang, the true pioneers of cottonii cultivation.
Today, the Philippine still leads in the red seaweed farming and carrageenan manufacturing in the world.
