Delineation of phytoplankton communities in this study was based on : 1 ) cluster analysis by Preston’s Equation (1962) and 2) analysis of the number of individuals . Results obtained by these two methods were very similar to that obtained in a previous study (Fig . 1 , Gu and Guo , 1982) based on analysis of the number of planktonic species of different ecological nature . Among these three methods , that based on cluster analysis (by which some subcommunities could be recognized ) proved to be the best.
