Abstract
Of the 1500 km coast of Namibia, only 80 km is predominantly rocky, the remaining 1420 km being sandy with only minor rocky outcrops. At present two species are utilized, Gracilaria verrucosa for agar and Laminaria schinzii for human consumption. Other potentially utilizable seaweeds occurring on the coast are Ecklonia maxima for alginates, Suhria vittata for agar, Gigartina radula, G. stiriata and Aeodes orbitosa for carrageenans and Porphyra capensis for human consumption. Laminaria schinzii also can be used for alginate production. Due to the diamond-mining areas around the 80 km rocky area at Luderitz (26° 39′ S), only 20 km are accessible; hence, at present the seaweeds are being exploited almost to their full potential. The species currently not being utilized could be used, however, to support the industry that already exists at Luderitz. To increase production, access to the diamond areas would have to be gained or a cultivation program initiated.
