The commercially valuable seaweeds of the Gulf of California

Botanica Marina 39(3): 201-206

The commercially valuable seaweeds of the Gulf of California

A list of potentially commercial seaweed species from the Gulf of California is reported based on a review of available literature and our own studies. At least 55 commercial species are listed based upon availability. The most abundant species are the phaeophytes Sargassum johnstonii and S. sinicola (a source of alginates and fertilizers), and the rhodophytes Eucheuma uncinatum and Gigartina pectinata (a source of carageenan). The most abundant chlorophytes are Ulva lactuca and Enteromorpha spp, which are used in medicine as well as for human consumption. The rhodophyte genera Gracilaria, Gelidium, Pterocladia and Laurencia are widely used as sources of agar and are represented by 19 species. the most abundant being Gracilaria lemanefromis. All the species found to have commercial application are annual. therefore commercial exploitation would necessitate culturing or careful planning of harvesting natural populations.
