Qualitative and quantitative analysis of the phytoplankton in the southern Adriatic, September – October 1979

Abstract

       Five groups of phytoplankton species distributed in re­gions with specific ecological conditions were established. Biomass of the phytoplankton was expressed as total cell volume per liter. The biomass at neritic stations showed 5.3 and 1.7 times higher values than in the open sea station. Bacillariophyceae were quantitatively the most significant group of microplankton at all stations. Nanoplankton, avera­ged 93.6% of the total number of phytoplankton cells. However its biomass was on the average only 15.4%. Nano­plankton biomass was increased at neritic polluted station.
