The portion of small Flagellata in the total amount and biomass of phytoplankton is determined. It is found that in some periods it may reach from 40 to 70-80% of the amount and above 20% of the biomass. Proceeding from the data on the division rate and on biomass, the diurnal production values are calculated which vary from 4 to 67 mgC/m³ for a year and may account for 3 to 93% of total diurnal production of phytoplankton.ru
