Resumo:  This study which was carried out at the different stations and sectors of Lake Burullus during the period from January till December 2000 showed that the identified species of phytoplankton community in Lake Burullus during the period of study included the classes of Bacillariophyceae, Cyanophyceae, Chlorophyceae, Euglenophyceae and Dinophyceae. The total number of species recorded during this period was 65 species. The standing crop and primary production of phytoplankton showed pronounced variations at different stations and months correlated with physicochemical conditions of water especially phosphate , nitrate and silicate contents. Stations 6,10 and 15 were the most productive in the eastern sector ,the middle sector, and the western sector respectively. The productivity was lower at stations nearby the drains mouth. Positive correlation was observed between the transparency and the net production. Levels of temperature and dissolved oxygen are among the factors affecting the productivity. In general, the dominance of Bacillariophyceae in the lake plays an important role in productivity, where it represented more than 65 % to the total count of phytoplankton during the period of study. The results obtained indicated that, Lake Burullus harboured lower phytoplankton standing crop and primary production as compared with that previously recorded .
