Abstract
The qualitative and quantitative data on phytoplankton of Sinoe lake
in a five years period, is summarised. The dominant systematic groups
had remained the same throughout the period. The Diatomeans have 
riched a peak in 1976-77 (54.28% and 53.52% respectively); the
Chlorophyceans in 1974 (32.05%) and Cyanophyceans in 1975 (25.00%).
Also, in all of the years, the freshwater species prevailed, both
qualitatively and quantitatively.
