Abstract :In this study, the seasonal variations in the macro-algal biomass in the Gulf of Antalya (north-eastern Mediterranean) were investigated. The seasonal variations of the macro-algal biomass were found to be related to the biology of the abundant species during less favourable seasons. These variations occurred usually as a result of a significant reduction in algal density [Padina pavonica (L.) J.V.Lamour., Dasycladus vermicularis (Scopoli) Krasser, Chondrophycus papillosus (C.Agardh) Garbay & Harper] or loss of major part of their thallus [Cystoseira spp., Liagora distenta (Mertens ex Roth) J.V.Lamour., Liagora viscida (Forssk.) C.Agardh]. The highest values of biomass were found to be in the unpolluted stations, while a progressive decrease in such values was observed as the effects of the anthropogenic pressure became more marked.
