Abstract
A study of phytoplankton primary productivity was carried out on Lake Lugano before the installation of sewage treatment plants.
Average day rates of 1.9 g C·m2 and annual production of 690 g C·m2 were estimated. Primary productivity was also evaluated by calculations based upon Secchi disc and light data. The results show the high cultural eutrophication state of this lake.
