On June, 30 - July, 6, 2010 in the different districts of the Crimean Black Sea coastal zone the total number (TNB) and biomass of bacterioplankton (BP), the abundance and species composition of metazoan microzooplankton (MZP) in the upper ~50 m layer of water were determined. TNB and biomass of BP ranged from 215 to 1.202 thousand cells ml-1 and 4.3 to 24.1 mg C m-3, respectively. Both middle for all array of data and the elevated concentrations of bacteria at some stations in the layers of peak (0.9 – 1.2 million cells ml-1) testified to the mesotrophic state of Crimean waters in an investigated period. The maximal concentrations of bacteria in south and south-west waters of the Crimean coast were typical for the layer of temperature "jump", and in south-east aquatoriums - in a layer under "thermocline". The waters in the Karadag area were the poorest, and the richest waters were in the seaward part of Kalamitsky Bay and near the Yalta coast. Nauplii of Copepoda and copepodites accounts for more than half the total number of MZP in the upper mixed layer, on the surface their share was often 70 – 80 % or more.
