Seaweed in the Spratly Islands are diverse and distributed unevenly , the research focused mainly in two directions is the geographical distribution ( distribution width) and vertical distribution ( depth distribution ).
Spratly Islands, Spratly district, Khanh Hoa province, comprising about 100 islands, coral reefs and beaches. It has many seaweed species survival and development, of which 62 species have economic value and are an important marine resources .

High value seaweed in Spratly islands

About cuisine, it has long been known seaweed as a food resource has more nutritional value and healing effects . Besides, even seaweed as raw materials for many industries such as food , textiles , cosmetics , pharmaceuticals , …. In Vietnam today , seaweed is one of the many subjects prospects exploited for socio-economic development , contributing to significantly change the face of rural areas especially rural areas and coastal islands .
To have a scientific basis , and additional resource materials on this group , over time , scientists from the Institute of Oceanography in Haiphong (now the Institute for Marine Resources and Environment ) has research on seaweed resources Spratlys and achieved many positive results .
The study showed that in 10 islands of the Spratly Islands ( Truong Sa large , Bill South , Son Ca , Song Tu Tay , Vinh Phan , Tan Speed , Fishing Boat , West Rock , Southern Rock and Conservation Biology ) , has identified 255 species of seaweed are 4 branches of the cyanobacteria ( Cyanophyta ) , red algae ( Rhodophyta ) , brown algae ( Phaeophyta ) and Luc algae ( Chlorophyta ) . In particular , the dominant red algae than 136 species accounted for 53.3 % , followed by Luc algae : 69 species accounted for 27.0 % , brown algae and cyanobacteria have equal number of species : 25 species accounting for 9 , 8 % .

Accordingly , the geographical distribution ( widely distributed ) of seaweed in the Spratly islands, not the same , the number of species in the islands range from 17 species ( Phan Vinh Island ) to 127 species ( Stone Island West ) and average 72.9 species .
The vertical distribution ( depth distribution ) of seaweed in the Spratlys only within the limits of the tide back down and concentrate mainly in the low tide . Some species may be distributed under 0m 20m deep or deeper charts .

Groups of algae

Based on the value in use, the scientists classify algae in the Spratlys group of six specific ingredients such as materials processing group gum Carrageenan , materials processing group agar ( agar ) , pharmaceutical , food , fertilizer and green vegetables .

Issues related resource extraction seaweed , Vietnam Academy of Science and Technology recommends : ” Should the term exploitation , exploitation alternating ( similar to the following ) in accordance with the laws of the flora tropical , and zoning should protect some species have small amounts of , in danger of extinction ” .
