Ocean and marine vegetation is dominated by algae, rocky shores being abundantly covered with macrovegetation that is almost exclusively seaweeds. Although the Black Sea shore is not very long and the conditions of the water are particular compared with other seas, we can find here some species that develop large biomass that make them suitable for harvesting and utilisation in different ways. In this paper we evaluated macroalgal biomass of some common genera of green and red alga (Chlorophyta and Rhodophyta) from our coasts. As the values are quite noticeable it is possible to use this valuable biomass as fertilizing resource, food for animals or as row material source for medicine and pharmacy.
