Abstract:

   Seasonal variability of phytoplankton biomass, “pure” primary production and its share consumed micro¬zooplankton, as well as the specific microzooplankton grazing rate of phytoplankton for the surface layer (0-1 m) in coastal waters of the Black Sea was studied. Almost 80% of the total annual primary’ produc¬tion of phytoplankton is created by phytoplankton with the average cell volume .from 150 to 4000 mm3. The main share of annual primary production, eaten by microzooplankton (86%) is also associated with these algae sized groups.

Key words: primary production, phytoplankton biomass, specific microzooplankton grazing rate of phytoplankton.
