Sažetak
During seven year period (1999-2005) phytoplankton assemblages of reservoir systems in Croatian part of Drava River (input/output waters and inner waters) were investigated. According to the Regulation on Water Qualification in Republic of Croatia the relevant water quality factors are abundance (cells per liter) of net-phytoplankton and Pantle-Buck saprobity index. Phytoplankton and water chemistry samples were collected seasonally four times a year at six different sites of three reservoirs. Phytoplankton samples were taken by filtrating 10 l of water through 25 μ m phytoplankton net. Index of saprobity was calculated for each sample. To explore the value of such monitoring procedure, on phytoplankton data set several more indices were calculated: Trophic Diatom Index that measures the effect of nutrients (mostly phosphorus) on the communities, tool for developing monitoring system according to the Water Framework Directive.
