The main goal of the Annual CBD Reporting for Black Sea is monitoring and assessment of Black Sea biodiversity. According to the terms of reference the purpose of the Advisory Group on Conservation of the Biological Diversity (AG CDB) is to provide the commission with best possible advice and information on the state of biological diversity in the Black Sea and propose measures for its protection, conservation and sustainable use as it deems necessary for the implementation of the Bucharest Convention, its Protocols, and the Black Sea Strategic Action Plan. The source of information is the Black Sea Information System (BSIS) the CBD Data Base. The format for the data base (EXCEL) was elaborated at meeting of the Advisory Group on Conservation of Biological Diversity BSC. It consists of 22 sections in separate sheets by which all Black Sea states annually contribute information on the main components of the Black Sea ecosystem, protected species, territories, changes in environmental legislation, etc. MEFRI, as the Black Sea Regional Activity Center for Biodiversity Conservation collected materials which characterize the state of the Georgian Black Sea coast and sent El-format CBD Report in Black Sea Commission (Turkey, Istanbul). To study the biodiversity of the Georgian shelf of the Black Sea have been used the conventional research methods. By our last data the phytoplankton species composition includes 203 species and subspecies which related to the following systematic groups: Bacillariophyta, Dinophyta, Chlorophyta, Cyanophyta, Chrizophyta, Euglenophyta. In total 215 zoobenthic species have been recorded in the region. The intensity of development of the benthic fauna is as follows: 78 species worms, 66 species molluscs, 57 species is crustaceous and other 13 species. From 184 fish species and subspecies occurring in the Black Sea (Rass, 1987), at the beginning of the 80s in Georgian coastal zone were spread 104 species (Meskhidze, Burchuladze, 1984), at the beginning of the 21st century were recorded 69 species and subspecies (Komakhdze et al, 2003).
