Abstract: Nanophytoplankton cell was preliminary studied by using flow cytometry (FCM) at surface and bottom layers in a eutrophic lake. Three populations could be rapidly discriminated and enumerated. Nanophytoplankton cell occupied the small part of total particles that were smaller than 50 mm. They represented 21.08% and 17.87% of total particles at surface and bottom layers respectively. FCM considerably improved the method of monitoring and studying on nanophytoplankton.

Key words: flow cytometry; eutrophication; nanophytoplankton cell
