Abstract

The work involved quantitative and qualitative studies of phytoplankton, together with measurement of primary productivity and of physical and chemical conditions. Investigations were made in two different ecological systems: Jijila, which is intensively cultivated and Crapina which is not. The balance of primary plankton production had positive values in both systems. In Jijila-Lake the primary production was higher and the biomass of phytoplankton was greater. This was attributed to the more intense cultivation.
