The phycocolloids of two species of red algae, Eucheuma denticulatum and Eucheuma striatum, were studied. Eucheuma denticu/atum was found to contain mainly iota carrageenan, while kappa carrageenan was the main component in Eucheuma striatum. The carrageenan content in E. denticu/atum varied from 50 to 55'Yo; in E. striatum it varied from 42 to 51 %. Considering these yields and the abundance of these species in the Toliara area, the two Eucheuma spp. Are attractive for industrial exploitation. Industrial exploitation of carrageenans started in the 1930s, and by 1989 the worldproduction was at 17000 tons (Amat, 1989). Among the species of sea weeds which areconsidered to have economic interests (Andriamampandry, 1976), Eucheuma denticu/atum (Burman) Collins and Harvey, and Eucheuma striatum (Schmitz) exist in abundance on the Toliara reef (southwest of Madagascar).Journal
