Abstract

The present investigation was mainly intended to make a recent data base of marine algal flora of Libyan coast which extend about 1900 Km. Seventy five marine algal species (53 genera) were collected and identified from two sampling stations at Tukra and Tolmeta coasts at the eastern Libyan coast. Eleven species (14.17%) belong to Chlorophyta, Seventeen species (22.67%) belonging to Phaeophyta (with special reference to genera Cystosiera) and forty seven species (62.67%) belonging to Rhodophyta which showed clear dominancy. The two coasts shared 17.33% of species (13). Tukra coast was richer of algal species (74.67%) all representing algal groups. It also characterized by 43 dominant species. Meanwhile, Tolmeta coast was relatively poor, only 32 species were found. Regarding to Chlorophyta, the similarity index between the two coasts was relatively high (70.59%). On the other hand, it was relatively low (30%, 15.69 and 27.21%) between Phaeophyta, Rhodophyta and total algae, respectively. Many of the collected algae are good ecological quality indicators having economic importance and need further investigations.
