Kappaphycus alvarezii, the elkhorn sea moss, is a species of red algae. The elkhorn sea moss varies in size, weight, and age. It is a dark greenish-brown hue and can sometimes be deep purple. The moss is cylindrical in shape throughout the seaweed. Its diameter averages 1.526 mm when dried. [1]
Eucheuma, commonly known as sea moss or gusô (/ ɡ u ˈ s ɔː ʔ /), is a rhodophyte seaweed that may vary in color (purple, brown, and green). Eucheuma species are used in the production of carrageenan, an ingredient for cosmetics, food processing, and industrial manufacturing, as well as a food source for people in the Philippines, Caribbean and parts of Indonesia and Malaysia.

Kappaphycus is a genus of red algae. Species are distributed in the waters of East Africa, Indonesia, Malaysia, Hainan Island, the Philippines, and Micronesia. [1] Genus Kappaphycus is "morphologically plastic", [2] with few visible characters that can be used to separate the taxa, so distinguishing the species can be difficult. In addition ...
The most commonly used sources are Eucheuma cottonii, Kappaphycus alvarezii, and Eucheuma spinosum, which together provide about three-quarters of the world production. [citation needed] These grow from the sea surface to a depth of about 2 m (6.6 ft). The seaweed is normally grown on nylon lines strung between bamboo floats, and it is ...
Sometimes lines are kept within net cages, to keep wild herbivores out. Growth takes two to three months, and most farmers are small-scale. This Eucheuma farming method is used for species such as Eucheuma denticulatum, but also species that were once considered Eucheuma but are now otherwise classified, such as Kappaphycus alvarezii.
The seven most cultivated taxa are Eucheuma spp., Kappaphycus alvarezii, Gracilaria spp., Saccharina japonica, Undaria pinnatifida, Pyropia spp., and Sargassum fusiforme. Eucheuma and K. alvarezii are attractive for carrageenan (a gelling agent); Gracilaria is farmed for agar; the rest are eaten after limited processing. [1]

The disease is known from seaweeds including Kappaphycus alvarezii and Eucheuma denticulatum, economically important sources of carrageenan. [2] [3] In countries where seaweed is harvested as a crop, ice-ice can wreak havoc on yields. Zamboanga, Philippines, had an outbreak of ice-ice in 2004, [1] and Bali, Indonesia, experienced an outbreak in ...
