Abstract : The paper gives a comparative estimate for density of population and biomass of bottom macrofauna in different biocoenoses for separate regions of the Black Sea. Total benthos biomass has been calculated for all the eight vast regions of the sea which characterizes the 'productivity' level of these regions. The most productive regions appeared to be the northwestern part of the sea and in the sea region, adjoining the Roumanian coast. High productivity of the above regions results from the great volume of continental flow carrying large quantities of nutrients. For the entire life zone of the sea botom, the total biomass of macrofauna (fish excepted) amounts to about 32,000,000 t. The average biomass of the benthic macrofauna for the entire sea will reach 305g/sq m. (Author)
