Abstract

Seasonal changes of nutrient concentrations, density and composition of phytoplankton and chlorophyll a contents in Bunnari lake were investigated to assess limnological conditions and trophyc status. Only 19 phytoplanktonic species are identified and only 2 species, during the seasonal succession, show high density and biomass; however seasonal succession is altered by a Cupper treatment with purpose of algal control. The 100% dominance of some species allow a good evaluation of chlorophyll aphytoplankton volume ratios. Since many of species found in the lake are typical of productive environments and the values of phytoplankton density and biomass, chlorophyll a and nutrient concentrations are very high, it has been argued a high eutrophic level of the lake.
