Anotace	Phosphatase activity in plankton was studied in seven subtropical shallow lakes of different exploitation management and trophic status in the urban area of Wuhan City. Bulk phosphatase activities were rather high (range: 1.1–11 µmol l–1 h–1), although concentrations of soluble reactive phosphorus (SRP) were as well high (range: 27 µg P l–1 to around 1.5 mg P l–1) in all lakes. Cell-associated extracellular phosphatase activity in phytoplankton was detected using the Fluorescence Labelled Enzyme Activity (FLEA) technique. Phytoplankton species partly contributed to bulk phosphatase activity with explicit differences in the presence of cell-associated phosphatase within the main phytoplankton groups. Furthermore, there is a certain potential of extracellular phosphatases produced by heterotrophic nanoflagellates in most of the lakes. This new finding compromises the ‘traditional’ interpretation of bulk phosphatase data as due to overall phytoplankton or bacterial P regeneration.
