Abstract

Phytoplankton community composition at Cau Khau Lake consists of 70 species and sub-species belonging to 6 algae phylum including Cyanobacteria, Bacillariophyta, Chlorphyta, Euglenophyta, Cryptophycophyta and Dinophycophyta. Cyanobacterial group predominates (77 to 85%) in the phytoplankton community. Nutrients from different land use types have a significant effect on the phytoplankton community structure in Cau Khau reservoir, Thach That Ha Noi. Land for growing rice and waste water added to Cua Khau lake have altered the phytoplankton community structure with reduced cell density and the diatom and Chlorphyta predominate in the Cyanobacterial group.

Keywords: Phytoplankton, Cua Khau, diatom
