Determination of the biomass and phycocolloid contents of some marine algae from Eritrea

الملخص EN

Specimens of five marine species of the brown (Cystoseira myrica, Sargassum torvum and Turbinaria ornata) and red (Gracilaria cortica and Gracilaria crassa) algae collected from the Red Sea coast of Eritrea were analyzed for their content of biomass and phycocolloids.

Sargassum torvum was found to be the dominant species of a maximum biomass.

Among the brown species, Turbinaria ornata was distinctive for its high content of alginic acid.

Amount of agar did not fluctuate greatly in Gracilaria species.
