(Table 2) Plankton biomass and production in the Burgas Bay, Black Sea

Distribution of mesoplankton in the Burgas Bay in 53 bottle samples taken in October-November 1982 is discussed. Decrease in total biomass of zooplankton from north to south can be traced at the northern meridional section (Cape Krotiriya to Cape Kaliakra), probably resulting from decrease in eutrophicating effect of the Danube River in this direction. Plankton off the Bulgarian coast was in typical autumn condition. In the southern part of the Burgas Bay, where there is discharge current carrying eutrophicated sewage from the city of Burgas, various stages in development of the community, from a young community in the inner end of the bay to a mature one at its outlet, were observed.
